Google OAuth 403刷新访问令牌时 [英] Google OAuth 403 when refreshing access token

问题描述

在UWP应用程序中，我首先使用以下端点获取刷新令牌和访问令牌：

  string tokenRequestBody = string.Format（code = {0}& redirect_uri = {1}& client_id = {2}& scope& grant_type = authorization_code，
 code，
 System.Uri.EscapeDataString （redirectURI），
 clientID 
）; 
 StringContent content = new StringContent（tokenRequestBody，Encoding.UTF8，application / x-www-form-urlencoded）; 
 HttpResponseMessage response = new HttpClient（）。PostAsync（https://www.googleapis.com/oauth2/v4/token，content）.Result; 
  

在响应中的这一点，我有一个刷新令牌和一个全功能的1小时访问令牌。这是行得通的。

现在我想使用刷新令牌来更新访问令牌：

  string tokenRequestBody = string.Format（client_id = {0}& refresh_token = {1}& grant_type = refresh_token，clientID，_refreshToken）; 
 StringContent body = new StringContent（tokenRequestBody，Encoding.UTF8，application / x-www-form-urlencoded）; 
 
 HttpResponseMessage tokenResponse = new HttpClient（）。PostAsync（https://www.googleapis.com/oauth2/v4/token，body）.Result; 
  

而不是获取新的访问令牌，我有以下错误：

  [{domain：usageLimits，reason：dailyLimitExceededUnreg，message：未经验证的使用的每日限制超出。注册。，extendedHelp：https://code.google.com/apis/console}]，code：403，message：未经验证的使用的每日限制超出，继续使用需要注册。 } 
  

我在这里错过了什么？

感谢您的帮助。

解决方案

好的，我真的很蠢。

上面的代码没有任何问题。

基本上我是这样做的：

  var dataResponse = getSomeStuffFromRestApi（）; 
 if（api授权失败）
 {
 var tokenResponse = getATokenFromRestApi（）; 
 lookForTokenInResponse（dataResponse）; //应该是tokenResponse ............. 
} 
  

对不起，浪费时间。至少有一些工作代码供参考....

In a UWP app, I first get a refresh token and an access token using the following endpoint :

string tokenRequestBody = string.Format("code={0}&redirect_uri={1}&client_id={2}&scope=&grant_type=authorization_code",
                code,
                System.Uri.EscapeDataString(redirectURI),
                clientID
                );
StringContent content = new StringContent(tokenRequestBody, Encoding.UTF8, "application/x-www-form-urlencoded");
HttpResponseMessage response = new HttpClient().PostAsync("https://www.googleapis.com/oauth2/v4/token", content).Result;

At this point in the response, i have a refresh token and a fully functional 1 hour access token. This is working fine.

Now i want to use the refresh token to renew the access token :

string tokenRequestBody = string.Format("client_id={0}&refresh_token={1}&grant_type=refresh_token", clientID, _refreshToken);
StringContent body = new StringContent(tokenRequestBody, Encoding.UTF8, "application/x-www-form-urlencoded");

HttpResponseMessage tokenResponse = new HttpClient().PostAsync("https://www.googleapis.com/oauth2/v4/token", body).Result;

Instead of getting a new access token, i have the following error :

[{"domain":"usageLimits","reason":"dailyLimitExceededUnreg","message":"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.","extendedHelp":"https://code.google.com/apis/console"}],"code":403,"message":"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."}

What am i missing here ?

Thanks for the help.

解决方案

Well, i'm amazingly stupid.

Nothing at all is wrong with the above code. I just parsed the wrong response.

Basically i did :

var dataResponse = getSomeStuffFromRestApi();
if (api authorization fails)
{
  var tokenResponse = getATokenFromRestApi();
  lookForTokenInResponse(dataResponse); // should've been tokenResponse.............
}

Sorry for the waste of time. At least there is some working code for reference now....
