I'm unable to access the Google spell check service located at this address:
https://www.google.com/tbproxy/spell
is anyone else having this problem? I keep getting "bad gateway" when I try to connect. I'm pretty sure the service is offline.
Is there any news on what's going on? I know Google Drive went down a few weeks ago with the same set of error messages.
You can try this below Java code. This doesn't require any API Key. But please note, if you run it frequently, it will stop working as google blocks the IP Address from making future calls. You can use it on small data set. Not ideal solution, but if it is part of some batch job which runs in a while, then this approach may be acceptable to you.
public static String getSpellCheckedText(String Text) throws Exception {
String google = "http://www.google.com/complete/search?output=toolbar&q=";
String search = Text;
String charset = "UTF-8";
String spellCheckedText = Text;
URL url = new URL(google + URLEncoder.encode(search, charset));
Reader reader = new InputStreamReader(url.openStream(), charset);
BufferedReader bufReader = new BufferedReader(reader);
String line = bufReader.readLine();
StringBuffer sBuffer = new StringBuffer();
while (line != null) {
sBuffer.append(line).append("\n");
line = bufReader.readLine();
}
String content = sBuffer.toString();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
InputSource is = new InputSource(new StringReader(content));
Document document = builder.parse(is);
NodeList nodeList = document.getElementsByTagName("suggestion");
if (nodeList != null && nodeList.getLength() > 0) {
org.w3c.dom.Node elm = nodeList.item(0);
if (elm.getNodeType() == Node.ELEMENT_NODE) {
Element suggestionElement = (Element)elm;
String suggestedString = suggestionElement.getAttribute("data");
if (suggestedString != null && suggestedString.trim().length() != 0) {
spellCheckedText = suggestedString.trim();
System.out.println(Text + " => "+ spellCheckedText);
}
}
}
return spellCheckedText;
}
I am also having this problem. I am getting a 503 Server Error. The problem is definitely on Google's end. (N.B. I am on Safari 6.0.3)
In specific...
503. That's an error.
The service you requested is not available at this time.
Service error -27. That’s all we know.
It seems as though Google is having some problems with their services. Hopefully they fix it soon!
Ditto, here. I really depend on it to check spelling in text boxes. It says "Unable to connect to Google spelling servers. Please check your internet connection and try again"

I'm trying to get google report activity by calling https://www.googleapis.com/admin/reports/v1/activity/users/all/applications/meet
I created a service account and I have to use the generated private key (json file) as access token.
My code was:
String PROTECTED_RESOURCE_URL = "https://www.googleapis.com/admin/reports/v1/activity/users/all/applications/meet?eventName=call_ended&maxResults=10&access_token=";
String graph = "";
try
{
JSONParser parser = new JSONParser();
JSONObject data = (JSONObject) parser.parse(
new FileReader("C:/Users/Administrateur/Desktop/GoogleApis/Interoperability-googleApis/target/classes/my-first-project-274515-361633451f1c.json"));//path to the JSON file.
String json_private_key = data.toJSONString();
URL urUserInfo = new URL(PROTECTED_RESOURCE_URL + json_private_key);
HttpURLConnection connObtainUserInfo = (HttpURLConnection) urUserInfo.openConnection();
if (connObtainUserInfo.getResponseCode() == HttpURLConnection.HTTP_OK)
{
StringBuilder sbLines = new StringBuilder("");
BufferedReader reader = new BufferedReader(new InputStreamReader(connObtainUserInfo.getInputStream(), "utf-8"));
String strLine = "";
while ((strLine = reader.readLine()) != null)
{
sbLines.append(strLine);
}
graph = sbLines.toString();
}
}
catch (IOException ex)
{
ex.printStackTrace();
}
System.out.println("--------------- Result: " + graph);
but I got null value.
Could you please tell me what I misses ?.
Big Thanks.
The Access Token is not part of your request URL. You can read here about the OAuth2 protocol and how it works.
However, Google built an API that enables you to authenticate your requests without worrying about the underlying OAuth2 process.
You should be using the Java Google Reports API to access activities. Here you can find the Java Quickstart that will help you with the first set up of your Java Application.
Here the Java translation of what you are trying to do, using the Google Reports API:
Reports service = new Reports.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
.setApplicationName(APPLICATION_NAME)
.build();
String userKey = "all";
String applicationName = "meet";
String eventName = "call_ended";
Activities result = service.activities().list(userKey, applicationName)
.setEventName(eventName)
.setMaxResults(10)
.execute();
Edit:
Be sure to use the last version of the Java API package. You can find the Java API docs here: https://developers.google.com/resources/api-libraries/documentation/admin/reports_v1/java/latest/
If you are using Gradle be sure to have this line in the dependencies parameter.
dependencies {
...
compile 'com.google.apis:google-api-services-admin-reports:reports_v1-rev89-1.25.0'
}

I have a question about this create/Update leads API, http://developers.marketo.com/documentation/rest/createupdate-leads/.
There is no sample code for C# or JAVA. Only ruby available. So I have to try it by myself. But I always get null return from the response.
Here is my code:
private async Task<CreateLeadResponseResult> CreateLead(string token)
{
string url = String.Format(marketoInstanceAddress+"/rest/v1/leads.json?access_token={0}", token);
var fullUri = new Uri(url, UriKind.Absolute);
CreateLeadResponseResult createLeadResponse = new CreateLeadResponseResult();
CreateLeadInput input = new CreateLeadInput { email = "123#123.com", lastName = "Lee", firstName = "testtesttest", postCode = "00000" };
CreateLeadInput input2 = new CreateLeadInput { email = "321#gagaga.com", lastName = "Lio", firstName = "ttttttt", postCode = "00000" };
List<CreateLeadInput> inputList = new List<CreateLeadInput>();
inputList.Add(input);
inputList.Add(input2);
CreateLeadRequest createLeadRequest = new CreateLeadRequest() { input = inputList };
JavaScriptSerializer createJsonString = new JavaScriptSerializer();
string inputJsonString = createJsonString.Serialize(createLeadRequest);
using (var client = new HttpClient())
{
HttpResponseMessage response = await client.PostAsJsonAsync(fullUri.OriginalString, inputJsonString).ConfigureAwait(false);
// I can see the JSON string is in the message body in debugging mode.
if (response.IsSuccessStatusCode)
{
createLeadResponse = await response.Content.ReadAsAsync<CreateLeadResponseResult>();
}
else
{
if (response.StatusCode == HttpStatusCode.Forbidden)
throw new AuthenticationException("Invalid username/password combination.");
else
throw new ApplicationException("Not able to get token");
}
}
return createLeadResponse;}
//get null here.
Thank you.

The best way to debug this is to capture the exact URL, parameters and JSON that are submitted by your app and try submitting those manually via a tool like Postman (Chrome plug-in) or SOAP UI. Then you see the exact error message, which you can look up here: http://developers.marketo.com/documentation/rest/error-codes/. Based on that you can update your code. I don't know much about Java, but this is how I got my Python code to work.
Your example code was really helpful in getting my own implementation off the ground. Thanks!
After playing with it for a bit, I realized that the JavaScriptSerializer step is unnecessary since PostAsJsonAsync automatically serializes whatever object you pass to it. The double serialization prevents Marketo's API from processing the input.
Also, I agree with Jep that Postman is super helpful. But in the case of this error, Postman was working fine (using the contents of inputJsonString) but my C# code still didn't work properly. So I temporarily modified the code to return a dynamic object instead of a CreateLeadResponseResult. In debugging mode this allowed me to see fields that were discarded because they didn't fit the CreateLeadResponseResult type, which led me to the solution above.
As I was reminded here, I need to probably use "ppp_peer" to programmatically connect from my Compact Framework app to my Web API app running on my PC.
I have tried this (replacing an IPAddress with "ppp_peer"):
string uri = string.Format("http://ppp_peer:28642/api/FileTransfer/GetHHSetupUpdate?serialNum={0}&clientVersion={1}", serNum, clientVer);
...but I get, "NullReferenceException" in "Main" (prior to this I got "Unable to Connect to the Remote Server").
I have a breakpoint in the server code, but it doesn't reach that, so it must be somewhere in the client where this is occurring.
The client code in context is:
string uri = string.Format("http://ppp_peer:28642/api/FileTransfer/GetHHSetupUpdate?serialNum={0}&clientVersion={1}", serNum, clientVer);
RESTfulMethods.DownloadNewerVersionOfHHSetup(uri);
. . .
public static void DownloadNewerVersionOfHHSetup(string uri)
{
string dateElements = DateTime.Now.ToString("yyyyMMddHHmmssfff", CultureInfo.InvariantCulture);
var outputFileName = string.Format("HHSetup_{0}.exe", dateElements);
try
{
var webRequest = (HttpWebRequest)WebRequest.Create(uri);
var webResponse = (HttpWebResponse)webRequest.GetResponse();
string statusCode = webResponse.StatusCode.ToString();
if (statusCode == "NoContent")
{
MessageBox.Show("You already have the newest available version.");
}
else
{
var responseStream = webResponse.GetResponseStream();
using (Stream file = File.Create(outputFileName))
{
CopyStream(responseStream, file);
MessageBox.Show(string.Format("New version downloaded to {0}", outputFileName));
}
}
}
catch (WebException webex)
{
string msg = webex.Message;
string innerEx = webex.InnerException.ToString();
string status = webex.Status.ToString();
MessageBox.Show(string.Format("Message: {0}; Status: {1}; inner Ex: {2}", msg, status, innerEx));
}
}
Do I need an IPAddress in addition to ppp_peer, or is my formatting of the URI wrong, or...???
UPDATE
After the "NRE" I also see, ""...encountered a serious error and must shut down"
I changed the code from above to see just what ppp_peer is translated as:
IPAddress ipAd = Dns.Resolve("PPP_PEER").AddressList[0];
string IPAddr = ipAd.ToString();
MessageBox.Show(IPAddr);
string uri = string.Format("http://{0}:28642/api/FileTransfer/GetHHSetupUpdate?serialNum={1}&clientVersion={2}", IPAddr, serNum, clientVer);
The MessageBox call shows me "192.168.55.100" which is different from what I thought my PC's IPAddress was...???
I get the same with:
IPAddress ipAd = Dns.GetHostEntry("PPP_PEER").AddressList[0];
UPDATE 2
Using this instead (I got it from here [Get ip address of host pc from windows mobile when connected via ActiveSync):
IPAddress ipAd = Dns.GetHostEntry(Dns.GetHostName()).AddressList[0];
...the IP Address displayed is "one up" (192.168.55.101), and instead of an NRE, I get:
Message: Unable to connect to the remote server; Status: ConnectFailure; inner Ex: System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it at System.Net.Sockets.SocketConnectNoCheck(EndPoint remoteEP) ...
So it seems I'm doing all I can on the client end, and the server hears the knock, but is not opening the door - am I right?
BTW, out of curiosity I also added this code:
string hostName = Dns.GetHostName();
MessageBox.Show(string.Format("host name is {0}", hostName));
...and I see "WindowsCE"
UPDATE 3
According to this post by Andy Wiggly (the cat/bloke who wrote "MS .NET Compact Framework"), you do use "ppp_peer":
HttpWebRequest request = REST.CreateRequest(#"http://ppp_peer/DataServicesWebsite/NorthwindService.svc/Customers",
HttpMethods.GET, String.Empty, #"application/atom+xml", "", "");
The interestingest thing about this is the lack of a port assignment (":28642" or whatever); however, this style also gives me an NRE (yes, kind of like a Null Ready to Eat).
UPDATE 4
So what uri will it take to access the host machine from the handheld device?
I have tried all of the following permutations from the client/Compact Framework app, and none work:
IPAddress ipAd = Dns.GetHostEntry(Dns.GetHostName()).AddressList[0];
string IPAddr = ipAd.ToString();
//string uri = string.Format("http://ppp_peer/api/...
//string uri = string.Format("http://ppp_peer:28642/api...
//string uri = string.Format("http://PPP_PEER/api/...
string uri = string.Format("http://PPP_PEER:28642/api/...
//string uri = string.Format("http://{0}:28642/api/...
//string uri = string.Format("http://192.168.125.50:28642/api/...
//string uri = string.Format("http://Platypus:28642/api/...
RESTfulMethods.DownloadNewerVersionOfHHSetup(uri);
The error is happening somewhere in that client code (can't step through it, so I don't know exactly where), because I have a breakpoint on the last line shown, and it is never reached.
SERVER (Web API) code:
[Route("api/FileTransfer/GetUpdatedHHSetup")]
public HttpResponseMessage GetUpdate(string serialNum, string clientVersion)
{
return _fileTransfer.GetHHSetupUpdate(serialNum, clientVersion);
}
public HttpResponseMessage GetHHSetupUpdate(string serialNum, string clientVersion)
{
HttpResponseMessage result;
string filePath = GetAvailableUpdateForCustomer(serialNum); // <= breakpoint on this
line
I put some debug lines in DownloadNewerVersionOfHHSetup() so that it now looks like this:
public static void DownloadNewerVersionOfHHSetup(string uri)
{
MessageBox.Show("Made it into DownloadNewerVersionOfHHSetup");
string dateElements = DateTime.Now.ToString("yyyyMMddHHmmssfff",
CultureInfo.InvariantCulture);
var outputFileName = string.Format("HHSetup_{0}.exe", dateElements);
try
{
var webRequest = (HttpWebRequest)WebRequest.Create(uri);
MessageBox.Show("Made it into DownloadNewerVersionOfHHSetup #2");
var webResponse = (HttpWebResponse)webRequest.GetResponse();
MessageBox.Show("Made it into DownloadNewerVersionOfHHSetup #3");
. . .
I never see "#3", so it must be a problem inside the call to GetResponse(), but how can I find out exactly what? I get the NRE, then "...encountered a serious error and must shut down"
This is where it tries to call the server but, as mentioned, it never makes it to the server method being called...
UPDATE 5
It turns out that this now works:
http://192.168.125.50:28642/api/
...and the main reason that it does is because there was a mismatch between my routing attribute (GetUpdatedHHSetup) and what I was calling from the client (GetHHSetupUpdate). Once I aligned those planets, the NRE went away, and I got the expected result.
PPP_PEER is not needed in the uri/connection string. Using the host PC's IP Address (and port number for the server/Web API app) works now (after fixing the mismatch between the routing attribute and what the client was calling it).
I reckon using the machine name would work just as well, too.
i am developing an windows phone 8 app , in my app i am calling services and downloading some data into my app.
i am testing my app in windows phone 8 emulator, many times it throws this error :
"The remote server returned an error: NotFound."
This is how i have created and used my httpwebrequest :-
public async Task<string> ServiceRequest(string serviceurl, string request, string methodname)
{
string response = "";
try
{
var httpwebrequest = WebRequest.Create(new Uri(serviceurl)) as HttpWebRequest;
httpwebrequest.Method = "POST";
httpwebrequest.Headers["SOAPAction"] = "http://tempuri.org/" + iTestservice + "/" + methodname + "";
httpwebrequest.ContentType = "text/xml";
byte[] data = Encoding.UTF8.GetBytes(request);
using (var requestStream = await Task<Stream>.Factory.FromAsync(httpwebrequest.BeginGetRequestStream, httpwebrequest.EndGetRequestStream, null))
{
await requestStream.WriteAsync(data, 0, data.Length);
}
var httpTask = httpRequest(httpwebrequest);
var completeTask = await Task.WhenAny(httpTask, TaskEx.Delay(300000));
if (completeTask == httpTask)
return await httpTask;
else
httpwebrequest.Abort();
throw new TimeoutException("Service Timed Out");

i am really not able to figure what was the issue
Please note :-
i tried to open the site (service URL which my app is trying to access) in my emulator browser , it opened correctly , i wasn't facing any issues.
1)is that the problem with my code, if so i request you please correct me ??
2)is this any emulator issue or any connectivity issue ??
3)is this any certification issue opening in emulator ??
Even after a long research to how to fix the issue i was not able to fix it .
Please Help me out.
Thanks in Advance.
I have come across this issue when the webservice requests take longer than 60 seconds. I have read reports that the emulator does not throw this error, but only an actual device. In my experience however, I have had this happen on both emulator and device. This is a default timeout setting that cannot be altered, even if you change it in the config. This issue has been around since WP7.
I've only found this question asked/blogged about once elsewhere. Seems that not a lot of people have picked this up.
AFAIK, Microsoft are aware of this, but don't plan on fixing it. (Proven by the fact that it has been around since WP7, and wasn't fixed for WP8). My guess is that they are of the opinion that web calls shouldn't be taking longer than 60 seconds in any case.
I just resolved it adding empty credentials to https requests, like this
httpwebrequest.Credentials = new NetworkCredential("", "");
here he explains why

i wrote a function for download a webpage : function like:
public string GetWebPage(string sURL)
{
System.Net.WebResponse objResponse = null;
System.Net.WebRequest objRequest = null;
System.IO.StreamReader objStreamReader = null;
string sResultPage = null;
try
{
objRequest = System.Net.HttpWebRequest.Create(sURL);
objResponse = objRequest.GetResponse();
objStreamReader = new System.IO.StreamReader(objResponse.GetResponseStream());
sResultPage = objStreamReader.ReadToEnd();
return sResultPage;
}
catch (Exception ex)
{
return "";
}
}
But my problem is that. when this function working at that time application goto freeze (not response) and that time my can't not do any thing. How can i solve this problem. when downloading at time user can do other thing in my application.
Welcome to the world of blocking IO.
Consider the following:
You want your program to download a web page and then return the first 10 letters it finds in the source html. Your code might look like this:
...
string page = GetWebPage("http://example.com"); // download web page
page = page.Substring(0, 10);
Console.WriteLine(page);
....
When your program calls GetWebPage(), it must WAIT for the web page to be fully downloaded before it can possibly try to call Substring() - else it may try to get the substring before it actually downloads the letters.
Now consider your program. You've got lots of code - maybe a GUI interface running - and it's all executing line by line one instruction at a time. When your code calls GetWebPage(), it can't possibly continue executing additional code until that request is fully finished. Your entire program is waiting on that request to finish.
The problem can be solved in a few different ways, and the best solution depends on exactly what you're doing with your code. Ideally, your code needs to execute asynchronously. c# has methods that can handle a lot of this for you, but one way or another, you're going to want to start some work - downloading the web page in your case - and then continue executing code until your main thread is notified that the webpage is fully downloaded. Then your main thread can begin parsing the return value.
I'm assuming that since you've asked this question, you are very new to threads and concurrency in general. You have a lot of work to do. Here are some resources for you to read up about threading and implementing concurrency in c#:
C# Thread Introduction
.NET Asynchronous IO Design
the best was is to use thread
new Thread(download).Start(url);
and if your download page size is large use chunk logic.
HttpWebRequest ObjHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(Convert.ToString(url));
ObjHttpWebRequest.AddRange(99204);
ObjHttpWebRequest.Timeout = Timeout.Infinite;
ObjHttpWebRequest.Method = "get";
HttpWebResponse ObjHttpWebResponse = (HttpWebResponse)ObjHttpWebRequest.GetResponse();
Stream ObjStream = ObjHttpWebResponse.GetResponseStream();
StreamReader ObjStreamReader = new StreamReader(ObjStream);
byte[] buffer = new byte[1224];
int length = 0;
while ((length = ObjStream.Read(buffer, 0, buffer.Length)) > 0)
{
downloaddata += Encoding.GetEncoding(936).GetString(buffer);
