Google 身份工具包 API PHP returns INVALID_CLIENT

Google Identity Toolkit API for PHP returns INVALID_CLIENT

我正在尝试让 Google Identity Toolkit API 为基于 PHP 的应用程序工作。

我一直在关注 Google 中的快速入门指南,此处提供: https://developers.google.com/identity/toolkit/web/quickstart/php

我已经完全按照步骤进行了(并反复检查)。

登录按钮显示在 index.php 页面上。单击此重定向到 widget.php 页面。我可以 select 我想用哪个帐户登录,然后当返回成功登录页面时(再次 index.php )我收到以下错误消息:

Fatal error: Uncaught exception 'Google_Auth_Exception' with message 'Error refreshing the OAuth2 token, message: '{ "error" : "invalid_client", "error_description" : "The OAuth client was invalid." }'

我尝试在 Google 开发人员控制台中重新创建 OAuth 客户端。提到检查电子邮件和项目名称字段的一些搜索结果已在 OAuth 同意屏幕上完成,所有这些我都完成了。

如有任何帮助和建议,我们将不胜感激。 注意:我只使用身份工具包 API 设置下的可用提供程序中的 "Google"。

我的 gitkit-server-config.json 文件:

{
  "clientId": "<my-client-id-here>",
  "projectId": "<my-project-id-here>",
  "serviceAccountEmail": "<my-serviceAccountEmail-here>",
  "serviceAccountPrivateKeyFile": "<my-p12-KeyFile-location-here>",
  "widgetUrl": "http://local.myfakedomain.com/gitkit",
  "cookieName": "gtoken"
}

在您的 gitkit-server-config.json 文件中,serviceAccountEmail 不应为空。您可以从 Google Developers Console 项目设置页面复制服务帐户电子邮件。

以及服务帐户电子邮件(类似于 "app-example-com@appname.example.com.iam.gserviceaccount.com",项目 ID 导致我出现问题。

我找到的解决方案是如果google说你的projectId是"example.com:appname",把它改成"appname"

我遇到了同样的问题,我通过在服务器配置代码中插入 "correct" 服务帐户电子邮件解决了这个问题:

{
  "clientId": "<my-client-id-here>",
  "projectId": "<my-project-id-here>",
  "serviceAccountEmail": "<Correct-serviceAccountEmail-here>",
  "serviceAccountPrivateKeyFile": "<my-p12-KeyFile-location-here>",
  "widgetUrl": "http://local.myfakedomain.com/gitkit",
  "cookieName": "gtoken"
}

诀窍是 serviceAccountEmail 不是您的 google 电子邮件,要找到正确的电子邮件,请转到 Credentials 然后在下面服务帐户密钥单击右侧的管理服务帐户 link,转到正在使用的服务并记下电子邮件字段。电子邮件很长,格式类似于 service-name@project-name.xxx.xxxxxxxxx.xxx
