我正在尝试将 Mule 3.5 连接到 Google API（任务、日历等），但我在 OAuth2 身份验证方面遇到了各种问题。

谁能给我一个 Mule 项目的示例 .xml 文件，其中包含一个有效的 Google OAuth2 示例（可能还有 Google 的 API 控制台中的设置），拜托。

一个链接也可以。

您需要使用创建项目按钮在您的 Google 开发者帐户 ( https://console.developers.google.com/ ) 中创建一个应用程序。记下您的项目 ID，您将在 Google 连接器配置中使用它。

然后，您需要单击应用程序并转到APIs & Auth。确保您需要的 API 设置为“开启”状态。在这种情况下，您可能想要打开日历并关闭您不需要的任何其他内容。请注意，对日历服务的大量调用可能会产生成本或配额限制。

此外，在 Google 开发者控制台左侧的 APIs & Auth 部分下，您需要选择凭据。然后点击红色按钮Create new client ID。这将为您提供两个关键信息：

  1. 客户端 ID - 这将进入 Mule 中 Google 连接器中的“consumerKey”
  2. Client Secret - 这进入 Mule 连接器中的“consumerSecret”

另一个重要的设置是重定向 URI。这将需要是这样的：

http://localhost:8081/oauth2callback

这需要与您放入连接器配置的内容相匹配。如果你在防火墙后面运行你的 Mule 服务器，你需要配置一些东西，比如你的代理，这样这个回调就可以到达你的服务器。

这是我设法开始工作的粗略示例。请务必根据需要替换 clientID clientSecret 和应用程序名称。

用于 Mule的Google 连接器套件有一个完整的示例，包括一个Mule XML 配置。

我们已经发布了关于如何使用 OAuth 连接器的文档。让我们知道它是否有帮助。
