无法在 POSTMan 上获取 Google oAuth 2 令牌 [英] Could not obtain Google oAuth 2 token on POSTMan

问题描述

好吧，由于 其他问题(已解决)仍未解决，我想使用POSTMan对Client库将要执行的每个步骤进行试错.

Well, since the Other problem(solved) remain unsolved, I was thinking to use POSTMan to do Trial and Error on each steps that the Client library will do.

所以我再次阅读了 Google OAuth2 的基本步骤，创建了另一个开发控制台Api Manager > Credentials中的OAuth 2 ID，ID类型为Web Application，填入POSTMan:

So I read the Basic steps of Google OAuth2 again, created another OAuth 2 ID at Api Manager > Credentials in Dev Console and ID type is Web Application, and filled them into the POSTMan:

1. POSTMan 中的新选项卡，然后单击授权标签.
2. 选择类型为 OAuth 2.0 并选择向 url 添加令牌"
3. 身份验证网址:https://accounts.google.com/o/oauth2/v2/auth
4. 访问令牌网址:https://www.googleapis.com/oauth2/v4/token
5. 客户 ID:[我刚刚收到的客户 ID]
6. 客户端密码:[我刚刚收到的客户端密码]
7. 范围:[空]
8. 授权类型:授权码
9. 在本地请求访问令牌:已选择
10. 点击请求令牌"
11. 邮递员回复我:无法完成 OAuth2.0 登录"

我错过了什么吗?

推荐答案

只有当 Google 用户通过 google 登录页面登录时，您才能获得访问令牌.

You get access Token only when a Google User Logs in through the google signin page.

第 1 步:重定向https://accounts.google.com/o/oauth2/auth?client_id=" + GoogleClientID + "&redirect_uri=" + Url.Encode(GoogleRedirectURL) + "&response_type=code&scope=email"

Step 1: Redirect https://accounts.google.com/o/oauth2/auth?client_id=" + GoogleClientID + "&redirect_uri=" + Url.Encode(GoogleRedirectURL) + "&response_type=code&scope=email"

第 2 步:现在您在 google 登录页面上，您将输入您的 google 凭据.

Step 2: Now you are on google signin page and you would enter your google credentials.

第 3 步:Google 会将您重定向回您在 Google Developer Console 中配置的 redirect_uri，您可以从 QueryString 中获取代码"

Step 3 : Google will redirect you back to the redirect_uri that you have configured in the Google Developer Console and you can get the "code" from the QueryString

第 4 步:现在您将表单发布到 https://www.googleapis.com/oauth2/v4/token使用 client_id、client_secret、redirect_uri、代码(您在第 3 步中获得)和 grant_type=authorization_code

Step 4: Now you post a form to https://www.googleapis.com/oauth2/v4/token with client_id, client_secret, redirect_uri, code(you obtained in Step 3), and the grant_type=authorization_code

结果:您现在应该会收到来自 Google 的 access_token

Result: You should now receive the access_token from Google
