我们收到了来自用户的报告，称我们的谷歌课堂集成中的事情无法正常工作。在摸索了一下之后，我们让用户发送他们的 HAR 文件，其中包含他们使用我们的 API 时的所有网络信息。在其中我们发现我们提出的请求：

 gapi.client.request({
   root: 'https://classroom.googleapis.com',
   path: 'v1/courses',
   params: {
     'pageSize': 1,
     'teacherId': 'me'
   }
 })

返回带有 nextPageToken 属性集但没有课程属性集的响应。

以下是 HAR 文件中的实际条目（减去 Authorization 标头）：

我已经让用户通过“试试看！”填写请求。api 描述中没有 pageSize 设置为 1 的区域，它会返回正确的格式。我们也无法使用我们的测试帐户进行复制，并且我们没有听到任何其他类似问题的报告。

有没有其他人遇到过这种情况或对可能发生的事情有任何想法？

没有任何关于 JSON 响应的格式不正确。pageSize设置 API 应返回的最大结果数，而不是最小值。您的代码应该处理设置的情况，nextPageToken但courses不是通过检索下一页直到它返回课程。

出于好奇，您为什么只检索一门课程？
