谷歌+ API错误禁止403

问题描述：

我使用这个网址来获得的accessToken谷歌+ API错误禁止403

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

下面是我使用

步骤获得一个代码授权

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";

以上url返回一个代码并使用我使用的代码交换accesstoken的代码。

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

这里是我的代码来获取的accessToken

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; 
     }

它未能在WebResponseGet方法。返回一个HTTP 403禁止编辑：可能我以前不清楚。为了解释这里的错误是它是什么代码在其请求失败的访问令牌

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" 
} 
}

您的问题是什么？ – Oded

答

http://www.googleapis.com/plus/v1/people/me是获取用户的个人资料（见docs for people.get）的端点。这是后您只能获得访问令牌。

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