I'm struggling with google api for a few days while sending a post request to Google sites API via C# application.
First I redeem the authorization code from google's servers by a GET request:
https://accounts.google.com/o/oauth2/auth?
scope=email%20profile&
state=security_token%3D138r5719ru3e1%26url%3Dhttps://oa2cb.mydomain/myHome&
redirect_uri=http://localhost&
response_type=code&
client_id= // CLIENT ID here...
access_type=online&
approval_prompt=auto
In the redirect uri I got the authorization code which I use to claim the
access token:
string RequestUrl;
RequestUrl = "https://www.googleapis.com/oauth2/v3/token";
WebRequest request = WebRequest.Create(RequestUrl);
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "code=4/aPJAhLvlGLxw1fjKDCOpEQjfoVtNDZYq7FzvrziUero#&" +
"client_id=//cilent id here&" +
"client_secret=client secret here&" +
"redirect_uri=http://localhost&" +
"grant_type=authorization_code";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = request.GetResponse();
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();
Console.WriteLine(responseFromServer);
reader.Close();
dataStream.Close();
response.Close();
The response containing the token looks like that:
{
"access_token": "ya29.pAGX8f4e0ZyBazzq5rxWVS6lL1jRyj0_GCog5UEO3FiGT2h4cj10jee4ziAoA09vHRoVejN5p7Iw",
"token_type": "Bearer",
"expires_in": 3600,
"id_token": "eyJhbGciOiJSUzI1NiIsImtpZCI6IjE2NWQ2MzcwZTgzOTI5YmE4Y2E4ZWU5OTMzZTExZjg2Yzg4YzAwNjUifQ.eyJpc3MiOiJhY2NvdW50cy5nb29nbGUuY29tIiwic3ViIjoiMTA1OTc0NjQwMTUzNzU0NjU1MDE5IiwiYXpwIjoiOTkwMzUxMjA1MzY4LXBudGYxZXNtaXQ3a3Zlbmg5cnRvbW5pMmdhMmY0N2ZsLmFwcHMuZ29vZ2xldXNlcmNvbnRlbnQuY29tIiwiZW1haWwiOiJuaXIuazFAaGFpZmFuZXQub3JnLmlsIiwiYXRfaGFzaCI6Imc5MU5wOVRYS2JUaVEzcFpTM2Ewa1EiLCJlbWFpbF92ZXJpZmllZCI6dHJ1ZSwiYXVkIjoiOTkwMzUxMjA1MzY4LXBudGYxZXNtaXQ3a3Zlbmg5cnRvbW5pMmdhMmY0N2ZsLmFwcHMuZ29vZ2xldXNlcmNvbnRlbnQuY29tIiwiaGQiOiJoYWlmYW5ldC5vcmcuaWwiLCJpYXQiOjE0MzU4MjI2ODAsImV4cCI6MTQzNTgyNjI4MH0.CeaQ8S3GG-yeAwqjU1ixdB7ro2SVKp2QdVTXNWl6196oJeQU1LFLpZ9FtrpNEGSDKHXrO5zx0ldE52RYw8TwMKILUqqCHLOewVJQMjZ6tiPzt-b-qeUta6Op4Z9HerwkMK2sofl88G-XZ6jKc7gk1gGPVcATBU7x0-QPRhQxmDUzP7zceVeoOtBD8g7liVHakK9sA5RNonGt-N6SvzECqhSLss7kDuXc4dStnENhyv_9oTIpvVsQplE-cJz7fDHC7mkW7BfwsgKBE8XbruBz5-o3AG5RVGyUTYqDaoq9qr3_NqckiRISUS127scaYwcYPE22Q8L_2AnpfJU0vuxo6g"
}
And the final step is to call the google api using the access_token
this way:
HttpWebRequest req = (HttpWebRequest)System.Net.WebRequest.Create("https://sites.google.com/feeds/site/mydomain");
req.ContentType = "application/atom+xml";
req.Host = "sites.google.com";
req.Method = "POST";
req.Headers["Gdata-version"] = "1.4";
req.Headers["Authorization"] = "Bearer ya29.pAGX8f4e0ZyBazzq5rxWVS6lL1jRyj0_GCog5UEO3FiGT2h4cj10jee4ziAoA09vHRoVejN5p7Iw";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes("<entry xmlns='http://www.w3.org/2005/Atom' xmlns:sites='http://schemas.google.com/sites/2008'><title>Source Site</title><summary>A new site to hold memories</summary><sites:theme>slate</sites:theme></entry>");
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
try
{
using (System.Net.WebResponse resp = req.GetResponse())
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()))
{
string i = sr.ReadToEnd().Trim();
}
}
}
catch (WebException ex)
{
using (var stream = ex.Response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
Console.WriteLine(reader.ReadToEnd());
}
}
But at the end of this step I get a 401 http error.
Token invalid - AuthSub token has wrong scope
What am I doing wrong?
Thanks in advance
you are authenticating your users using the following scopes
scope=email%20profile&
The Sites Data API uses the following scope: https://sites.google.com/feeds/.
I got problem on oauth2 handshake, as the eventbrite documentation is not very clear.
http://developer.eventbrite.com/doc/authentication/oauth2/ -> number 4
what i currently do is like this
WebRequest webRequest = WebRequest.Create("https://www.eventbrite.com/oauth/token");
string URLEncoded = "code=" + token + "&client_secret=" + APISecret + "&client_id=" + APIKey + "&grant_type=authorization_code";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.UTF8.GetBytes(URLEncoded);
Stream os = null;
try
{
os = await webRequest.GetRequestStreamAsync();
os.Write(bytes, 0, bytes.Length);
WebResponse response = await webRequest.GetResponseAsync();
os = response.GetResponseStream();
StreamReader reader = new StreamReader(os);
string responseFromServer = reader.ReadToEnd();
}
catch (WebException ex)
{
string err = ex.ToString();
}
finally
{
if (os != null)
{
os.Dispose();
}
}
Can someone give tips on this? i keep getting BAD REQUEST as a result. Thank you
edited : the response say : code is invalid or expired
I know its clear, but i already implement and get the token to exchange, use Secret API key and API Key to get it, but how come its invalid/expired?
I'm writing a window application by C# to auto login & post topic to a website. I've tried to pass username & password as the method following but the responseText did not changed. I meant if I passed the incorrect username or password the responseText would be included the "Error text such: wrong password or username" or if I passed to right username & password the responseText would be included "Login successfully" but the responseText I received was like a original login page
Do you have any idea? Thank you so much
private string Login()
{
HttpWebRequest request;
CookieContainer cookieContainer = new CookieContainer();
string cookieHeader = string.Empty;
byte[] byteArray = Encoding.UTF8.GetBytes("username=abc#gmail.com&password=123");

request.Method = "POST";

request.ContentLength = byteArray.Length;
using (Stream os = request.GetRequestStream())
{

}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string pageSource;
using (StreamReader sr = new StreamReader(response.GetResponseStream()))

I spent too much hours to overcome this, till now with no success
From my site which is developed in MVC im trying to send a login request to a remote site, for example, facebook.
From fiddler It seems that the following inputs are required charset_test, lsd, locale,email, pass.
lsd key seems to be the unique token
Here is my code
CookieContainer cookies = new CookieContainer()
private string GetToken()
{
Uri uri = new Uri("http://www.facebook.com");
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.CookieContainer = cookies;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string htmlText = reader.ReadToEnd();
HtmlDocument document = new HtmlDocument(); --> HtmlAgilePack object
document.LoadHtml(htmlText);
//Need to check xpath doesn't return null object
HtmlNode node = document.DocumentNode.SelectNodes("//input[#name='lsd']").First();
return node.Attributes["Value"].Value;
}
private void Login()
{
string postData = string.Format("charset_test=fixcharset_test&lsd={0} &locale=en_US&email=myemail&pass=mypass", HttpUtility.UrlEncode(GetToken()));
Uri uri = new Uri("http://www.facebook.com/login.php");
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.CookieContainer = cookies;
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postData.Length;
request.Method = "POST";
request.AllowAutoRedirect = true;
StreamWriter requestWriter = new StreamWriter(request.GetRequestStream());
requestWriter.Write(postData);
requestWriter.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
}
//After login to facebook suppose to
public string void AddFriend()
{
Uri uri = new Uri("http://www.facebook.com");
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.CookieContainer = cookies;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string status = response.StatusDescription;
StreamReader responseReader = new StreamReader(response.GetResponseStream());
string responseData = responseReader.ReadToEnd();
responseReader.Close();
return responseDat
}
Keep in mind, that facebook is just an example, Im aware of its API, Im trying to login to site with no API.
sadly, the response return a facebook page with a sorry message for unrecognizing my browser.
Any help will be more than appreciate.
Thanks,
Are you setting HTTP_USER_AGENT on your request?
