javascript - 使用 Javascript 通过 Google 客户端库进行批量请求

Question

我正在尝试使用 Google 的客户端库 API 请求多个记录。我正在尝试获取与单个谷歌类(class)相关的学生列表和单独的作业列表。我正在使用 Google Classroom API ( https://developers.google.com/classroom/reference/rest/ )。

这是我到目前为止所得到的:

    let batch = gapi.client.newBatch();

    let courseWorkRequest = function(courseId) {
        return gapi.client.request({
            'path': `/v1/courses/${courseId}/courseWork`,
        });
    };

    let studentRequest = function (courseId) {
        return gapi.client.request({
            'path': `/v1/courses/${courseId}/students`
        });
    };

    listOfGoogleClasses.forEach(function (course) {
        let courseAssignments = courseWorkRequest(course.id);
        batch.add(courseAssignments);
        let courseStudents = studentRequest(course.id);
        batch.add(courseStudents)
    });

    batch.then(function(response){
        console.log(response);
    });

请求有效，但对于响应，我只是得到一系列如下所示的对象:

  body:"Not Found"
  headers:Object
  result:false
  status:404
  statusText: "Not Found"

从错误本身推断，这意味着您缺少请求正文的一些必需属性，例如 Content-Type、Content-Length 等。示例可以在 Example batch request 中查看。

POST https://classroom.googleapis.com/batch HTTP/1.1
Authorization: Bearer your_auth_token
Content-Type: multipart/mixed; boundary=batch_foobarbaz
Content-Length: total_content_length

--batch_foobarbaz
