安装应用程序的OAuth 2.0 - 我在哪里获得redirect_uri [英] OAuth 2.0 for Installed Applications - where do I get a redirect_uri

问题描述

我正在按照说明使用OAuth2在安装的（Windows）应用程序中访问Gmail，网址 https://developers.google.com/identity/protocols/OAuth2InstalledApp 。这一切似乎很简单，直到我接触到做出令牌请求的部分。我需要做的一个参数是redirect_uri，它表示您从开发者控制台获得的重定向URI。

我已经获得了我的ClientID和ClientSecret从开发者控制台，但看不到任何我从它redirect_uri。

我缺少什么？感谢。

解决方案

身份验证基本上是一个三步或四步的过程

第一步是获取认证码。此链接可以放在任何浏览器窗口中的HTTP GET

https://accounts.google.com/o/oauth2/auth?client_id= {clientid} .apps.googleusercontent.com& redirect_uri = urn ：ietf：wg：oauth：2.0：oob& scope = https：// www。 googleapis.com/auth/analytics.readonly&response_type=code

一旦用户接受访问权限，您将获得一个认证码。

该代码被发送回服务器以获取刷新令牌和第一个访问令牌。这是一个HTTP POST。

  https://accounts.google.com/o/oauth2/token 
 code = 4 / X9lG6uWd8-MMJPElWggHZRzyFKtp.QubAT_P-GEwePvB8fYmgkJzntDnaiAI& client_id = {ClientId} .apps.googleusercontent.com& client_secret = {ClientSecret}& redirect_uri = urn：ietf：wg：oauth：2.0：oob& grant_type = authorization_code 
  

回复将如下所示

  {
access_token：ya29.1.AADtN_VSBMC2Ga2lhxsTKjVQ_ROco8VbD6h01aj4PcKHLm6qvHbNtn-_BIzXMw，
token_type：承载者，
expires_in：3600，
refresh_token：1 / J-3zPA8XR1o_cXebV9sDKn_f5MTqaFhKFxH-3PUPiJ4
} 
  

访问令牌只能运行一个小时，并且在此之后您将需要使用刷新令牌来获取新的访问令牌。

这也是一个HTTP Post

  https://accounts.google.com/o/oauth2/token 
 client_id = {ClientId} .apps .googleusercontent.com& amp; client_secret = {ClientSecret}& refresh_token = 1 / ffYmfI0sjR54Ft9oupubLzrJhD1hZS5tWQcyAvNECCA& grant_type = refresh_token 
  

response

  {
access_token：ya29.1.AADtN_XK16As2ZHlScqOxGtntIlevNcasMSPwGiE3pe5ANZfrmJTcsI3ZtAjv4sDrPDRnQ，
token_type：Bearer ，
expires_in：3600 
} 
  

代码已从我的教程谷歌3 lega oauth2 它有比这更多的解释。

I'm working through the instructions to use OAuth2 to get access to Gmail in an installed (Windows) application, on the page https://developers.google.com/identity/protocols/OAuth2InstalledApp. It all seems straightforward until I get to the part about "making a token request". One of the parameters to the POST I have to do is redirect_uri, which it says is "The redirect URI you obtained from the Developers Console."

I have obtained my ClientID and ClientSecret from the Developers Console, but can't see anywhere that I get a redirect_uri from it.

What am I missing? Thanks.

解决方案

Authentication is baslicy a three or four step process

Step one is just getting the authentication code. this link can be placed in any browser window its a HTTP GET

https://accounts.google.com/o/oauth2/auth?client_id={clientid}.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=https://www.googleapis.com/auth/analytics.readonly&response_type=code

Once the user has accepted access you will be given an authentication code.

That code is sent back to the server to get a refresh token and the first access token. this is a HTTP POST.

https://accounts.google.com/o/oauth2/token
code=4/X9lG6uWd8-MMJPElWggHZRzyFKtp.QubAT_P-GEwePvB8fYmgkJzntDnaiAI&client_id={ClientId}.apps.googleusercontent.com&client_secret={ClientSecret}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&grant_type=authorization_code

The response will be something like this

{
"access_token" : "ya29.1.AADtN_VSBMC2Ga2lhxsTKjVQ_ROco8VbD6h01aj4PcKHLm6qvHbNtn-_BIzXMw",
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : "1/J-3zPA8XR1o_cXebV9sDKn_f5MTqaFhKFxH-3PUPiJ4"
}

The access token will only work for one hour and it will expire after that you will need to use the refresh token to get a new access token.

This is also a HTTP Post

https://accounts.google.com/o/oauth2/token
client_id={ClientId}.apps.googleusercontent.com&client_secret={ClientSecret}&refresh_token=1/ffYmfI0sjR54Ft9oupubLzrJhD1hZS5tWQcyAvNECCA&grant_type=refresh_token

response

{
"access_token" : "ya29.1.AADtN_XK16As2ZHlScqOxGtntIlevNcasMSPwGiE3pe5ANZfrmJTcsI3ZtAjv4sDrPDRnQ",
"token_type" : "Bearer",
"expires_in" : 3600
}

code has been ripped from my tutorial Google 3 legged oauth2 it has more explanation than this.
