错误:redirect_uri_mismatch Google API oauth2获取访问令牌 [英] Error: redirect_uri_mismatch google api oauth2 to get access token

问题描述

在我的代码中出现以下错误.

Getting following error in my code.

400错误的请求 { 错误":"redirect_uri_mismatch" }

400 Bad Request { "error" : "redirect_uri_mismatch" }

我不明白这是怎么回事.我似乎在正确地使用Google api的规范中所定义的.在开发人员控制台中创建安装的应用程序后，我从浏览器获取了授权代码并将其插入.从控制台中提取了redirect_uri.谁能指出我redirect_uri出了什么问题.我一直无法弄清楚该参数出了什么问题.

I don't understand what is wrong. I seemed to be using google api's correctly as defined in their specifications. After creating a installed app in the developer console I got the authorization code from the browser and plugged it in. The redirect_uri was picked from the console. Can anyone point to me what is wrong with the redirect_uri. I haven't been able to figure out what is wrong with that parameter.

推荐答案

您的指针正确.

我为错误的问题on了两天.

I was scratching my head for two days on what was wrong.

显然，redirect_uri需要在auth和令牌请求之间匹配.

Apparently the redirect_uri need to match between auth and token requests.

如果不是，则将引发redirect_uri_mismatch.

The redirect_uri_mismatch will be thrown if it is not.

google api的文档说要使用 developer-console 中的 redirect_uri .
但是，他们自动生成并粘贴到浏览器中的URL不会执行此操作，而是使用与 localhost + port 不同的url.
这是问题的根本根源.

The documentation for google api says to use the redirect_uri from the developer-console.
However, the url that they auto-generate, to paste in the browser, doesn't do that, and uses a localhost + port url that is different.
This was fundamental source of problem.

如果您使用身份验证URL，他们会要求您剪切并粘贴到浏览器中，然后从控制台插入正确的 redirect_uri "urn:ietf:wg:oauth:2.0:oob"并获取代码，然后使用相同的redirect_uri获取令牌，然后没有redirect_uri_mismatch.
感谢您的回答.

If you take the auth url, that they asked you to cut and paste in browser, and plug in the correct redirect_uri "urn:ietf:wg:oauth:2.0:oob" from the console and get the code, then use the same redirect_uri to get the token, then there is no redirect_uri_mismatch.
Thanks for your answer.
