[英]The remote server returned an error: (401) Unauthorized
我正在嘗試通過使用此代碼從Windows Live Connect API獲取訪問令牌
字符串requestUrl =“ https://consent.live.com/AccessToken.aspx”;
// Request the access token.
string postData = string.Format("{0}?wrap_client_id={1}&wrap_client_secret={2}&wrap_callback={3}&wrap_verification_code={4}&idtype={5}",
requestUrl,
"000000004C039809",
"l4VJekL1vFL1iFVmcP5qLkWv9ukY4mdl",
"http://ewshops.com",
"dac5d71d-d640-30d1-ebed-3576b132b3ec",
"cid");
byte[] postDataEncoded = System.Text.Encoding.UTF8.GetBytes(postData);
WebRequest req = HttpWebRequest.Create(requestUrl);
req.Method = "POST";
// req.
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = postDataEncoded.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(postDataEncoded, 0, postDataEncoded.Length);
WebResponse res = req.GetResponse();
string responseBody = null;
using (StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.UTF8))
{
responseBody = sr.ReadToEnd();
}
// Process FORM POST.
NameValueCollection responseCollection = System.Web.HttpUtility.ParseQueryString(responseBody);
return responseCollection["wrap_access_token"];
但我收到以下錯誤
遠程服務器返回錯誤:(401)未經授權。
向我們顯示響應正文,它通常包含更多信息。 在將其添加到uri之前,您還應該urlencode http://ewshops.com
。
我遇到了同樣的問題,並按以下步驟進行修復。 刪除requestUrl(“ https://consent.live.com/AccessToken.aspx”)和后續的“?” 從您的postData中。 POST數據應采用x-www-form-urlencoded格式,並且不包含請求URL。 也是HttpUtility.UrlEncode()的所有參數。
