无法使 Gmail 上下文小工具工作 - 2015 API 版本

Question

我目前正在为一家非营利组织开发 Gmail 上下文小工具。我们遵循 https://developers.google.com/gmail/contextual_gadgets 上的官方 Google 教程，目标是构建 Hello World 应用程序。

我们做了以下工作：

在 https://console.developers.google.com/
激活Google Marketplace SDK
使用适当的提取器和小工具 URL 激活 GMail 上下文小工具。
为非营利组织用户部署应用程序。
向我们发送包含 "Hello World".

但是，我们无法让它工作（它应该在电子邮件下方打印 Hello World）。我们检查了托管 XM 的服务器，Google 肯定命中了我们的 gadget_helloworld.xml 文件。

文件内容如下。有人可以帮忙解决这个问题吗？

很难找到关于此主题的最新文档，因为 Google API 改变了很多东西。我认为提供一个在 2015 年最后更新的开源工作代码示例会对社区有所帮助。

最佳，

Answer 1

我有一个类似的问题，它没有激活，我的解决方案是将 "Extractor param name" 设置为 "hello" 并将 "Extractor param value" 设置为“.*” - - According to the docs 重要的部分是值域：

If you really do want your gadget to be triggered by all possible values in the extractor's default output, explicitly set the regular expression as value=".*". This makes it clear that you have cast a wide net by design.
