Question

我正在使用此网址获取accessstoken

http://www.googleapis.com/plus/v1/people/me?access_token?client_id=*********.ps.googleusercontent.com&redirect_uri=http://localhost:49261/Default.aspx&client_secret=*******************

以下是我正在使用的步骤

获取授权代码

 string url = string.Format("{0}?client_id={1}&redirect_uri={2}", AUTHORIZE, this.ConsumerKey, CALLBACK_URL);
 url += "&scope=https://www.googleapis.com/auth/plus.me&response_type=code";

上面的url返回一个代码并使用我正在使用的代码交换代码以进行访问。

 http://www.googleapis.com/plus/v1/people/me?access_token?client_id=*********.ps.googleusercontent.com&redirect_uri=http://localhost:49261/Default.aspx&client_secret=*******************

这是获取accessstoken

的代码

public void AccessTokenGet(string authToken)
        {
            this.Token = authToken;
            string accessTokenUrl = string.Format("{0}?client_id={1}&redirect_uri={2}&client_secret={3}&code={4}",
            ACCESS_TOKEN, this.ConsumerKey, CALLBACK_URL, this.ConsumerSecret, authToken);

            string response = WebRequest(Method.GET, accessTokenUrl, String.Empty);

            if (response.Length > 0)
            {
                //Store the returned access_token
                NameValueCollection qs = HttpUtility.ParseQueryString(response);

                if (qs["access_token"] != null)
                {
                    this.Token = qs["access_token"];
                }
            }
        }


        public string WebRequest(Method method, string url, string postData)
        {

            HttpWebRequest webRequest = null;
            StreamWriter requestWriter = null;
            string responseData = "";

            webRequest = System.Net.WebRequest.Create(url) as HttpWebRequest;
            webRequest.Method = method.ToString();
            webRequest.ServicePoint.Expect100Continue = false;
            webRequest.UserAgent = "[You user agent]";
            webRequest.Timeout = 20000;


            if (method == Method.POST)
            {
                webRequest.ContentType = "application/x-www-form-urlencoded";

                //POST the data.
                requestWriter = new StreamWriter(webRequest.GetRequestStream());

                try
                {
                    requestWriter.Write(postData);
                }
                catch
                {
                    throw;
                }

                finally
                {
                    requestWriter.Close();
                    requestWriter = null;
                }
            }

            responseData = WebResponseGet(webRequest);
            webRequest = null;
            return responseData;
        }


        public string WebResponseGet(HttpWebRequest webRequest)
        {
            StreamReader responseReader = null;
            string responseData = "";

            try
            {
                responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
                responseData = responseReader.ReadToEnd();
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                webRequest.GetResponse().GetResponseStream().Close();
                responseReader.Close();
                responseReader = null;
            }

            return responseData;
        }

WebResponseGet方法失败。返回禁止的HTTP 403 编辑：可能我早些时候不清楚。要解释这里的错误是什么代码对访问令牌

的请求失败

error: {
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "dailyLimitExceededUnreg",
    "message": "Daily Limit Exceeded. Please sign up",
    "extendedHelp": "https://code.google.com/apis/console"
   }
  ],
  "code": 403,
  "message": "Daily Limit Exceeded. Please sign up"
 }
}

http://www.googleapis.com/plus/v1/people/me是获取用户个人资料的端点（请参阅docs for people.get）。只有在获得访问令牌后才能调用。

实际获取访问令牌的端点是https://accounts.google.com/o/oauth2/token。根据您要使用的OAuth2流，您传递给该端点的确切参数会略有不同，但所有参数都记录在http://code.google.com/apis/accounts/docs/OAuth2.html
