Round 400 Bad Request responsed when getting the Access Token
I am trying to authenticate my remote access app, I can successfully get the code in the first step but when I send the second post to https://login.salesforce.com/services/oauth2/token I get a 400 Bad Request. Here is the .net code I am using, anyone have any ideas why this might not be working?
public string PostWebRequest(string postUrl, string paramData, Encoding dataEncode)
{
string ret = string.Empty;
try
{
byte[] byteArray = dataEncode.GetBytes(paramData);
HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(postUrl));
webReq.Method = "POST";
webReq.ContentType = "application/x-www-form-urlencoded";
webReq.ContentLength = byteArray.Length;
Stream newStream = webReq.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);//写入参数
newStream.Close();
HttpWebResponse response = (HttpWebResponse)webReq.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.Default);
ret = sr.ReadToEnd();
sr.Close();
response.Close();
newStream.Close();
}
catch (WebException e)
{
Response.Write(e.Message);
}
return ret;
}
