Question

我正在尝试将Mule 3.5连接到Google API（任务，日历等），但我遇到了OAuth2身份验证的各种问题。

有人可以给我一个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 API控制台中的设置）。

链接也可以。

Answer 1

您需要使用创建项目按钮在Google Developer帐户（https://console.developers.google.com/）中创建应用程序。请注意您在Google连接器配置中需要的项目ID。

然后，您需要点击该应用程序，然后转到 API＆amp;验证即可。确保您需要的API设置为“ON”状态。在这种情况下，您可能希望打开日历以及其他任何不需要的东西。请注意，对日历服务的大量调用可能会产生费用或配额限制。

同样在API＆amp;在Google开发者控制台左侧的Auth部分，您需要选择凭据。然后点击红色按钮创建新客户ID 。这将为您提供两个关键信息：

客户端ID - 这将进入Mule
客户端秘密 - 这将进入骡子中的“consumerSecret” 连接器

设置的另一个重要事项是重定向URI。这需要像：

http://localhost:8081/oauth2callback

这需要与您在连接器配置中添加的内容相匹配。如果您在防火墙后面运行Mule服务器，则需要配置代理等内容，以便此回调可以到达您的服务器。

这是一个粗略的例子，我已经设法开始工作。请务必根据需要替换clientID clientSecret和应用程序名称。
