我正在尝试检索 oauth 访问 token 以调用 asp.net mvc 中的某些 google api,并且我为操作编写了以下代码:
public ActionResult GetOAuthToken()
{
String url = "https://accounts.google.com/o/oauth2/token";
// Create a request using a URL that can receive a post.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
// Set the Method property of the request to POST.
request.Method = "POST";
request.Host = "accounts.google.com";
// Create POST data and convert it to a byte array.
string postData = String.Format("code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type=authorization_code", Request.QueryString["code"].ToString(), OAuthConfig.client_id, OAuthConfig.client_secret, OAuthConfig.token_redirect_uri);
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] byteArray = encoding.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// SOME CODE TO PROCESS THE RESPONSE
Response.Redirect("/Home");
return View();
}
OAuthConfig 只是一个包含客户端 ID、客户端密码等的类。
我不断收到“远程服务器返回错误:(400) 错误请求”。在 request.GetResponse() 行。我哪里错了?
最佳答案
Google 确实提供了一个更高级别的库来处理其服务,它处理 url 的格式,我发现它使使用他们的 api 变得容易得多。参见 http://code.google.com/p/google-api-dotnet-client/
