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'm trying to send a POST request to the Livecoin API. I have ensured that every parameter and the encoding is correct, but I keep getting a weird response:
{"success":false,"exception": "Unknown currency pair [currencyPair={1}]|null"}
This is what I'm trying to post:
string response = PrivatePostQuery("exchange/buymarket", "currencyPair=BTC/USD&price=12&amount=12");
And this is the method:
public string PrivatePostQuery(string requestUrl, string parameters = "")
{
parameters = http_build_query(parameters);
string Sign = HashHMAC(this.Exchange.ExchangeConnection.ApiSecretKey, parameters).ToUpper();
string uri = this.Exchange.ExchangeConnection.ApiUrl + requestUrl + "?" + parameters;
byte[] bytes = Encoding.UTF8.GetBytes(parameters);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;
request.Headers["Api-Key"] = this.Exchange.ExchangeConnection.ApiKey;
request.Headers["Sign"] = Sign;
Stream dataStream = request.GetRequestStream();
dataStream.Write(bytes, 0, bytes.Length);
try
{
WebResponse WebResponse = request.GetResponse();
dataStream = WebResponse.GetResponseStream();
StreamReader StreamReader = new StreamReader(dataStream);
return StreamReader.ReadToEnd();
}
catch (WebException ex)
{
return new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
}
}
I have succeeded getting tickers and my balance from the API, so the problem is not because of the signature or headers.
I have tried changing the request to upper / lower case, and adding the parameters as request headers, with and without them in URL.
Thanks for the help!
Ok so there was no problem at all, LiveCoin exchange doesn't work with BTC-USDT pair, only with BTC-USD. So the response was correct, even tough it was a bit messy.

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 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?
