Microsoft Graph-POST请求错误20132

Question

我似乎无法获得使用Microsoft Graph创建作业的POST请求。

在Graph Explorer和PHP中，我都遇到相同的错误："message": "The content of the request is invalid. Common causes are an invalid Content-Type header or no content in the body.",

端点：https://graph.microsoft.com/beta/education/classes/class-id/assignments

请求标头：content-type: application/json

身体：

{
  "dueDateTime": "2014-02-01T00:00:00Z",
  "displayName": "Midterm 1",
    "instructions":  {
      "contentType": "Text",
      "content": "Read chapters 1 through 3"
    },
      "grading": {
        "@odata.type": "#microsoft.education.assignments.api.educationAssignmentPointsGradeType",
        "maxPoints": 100
      },
      "assignTo": {
        "@odata.type": "#microsoft.education.assignments.api.educationAssignmentClassRecipient"
      },
      "status":"draft",
      "allowStudentsToAddResourcesToSubmission": true
}

任何帮助将不胜感激！

弄清楚了。从有效的说明中删除"contentType": "Text"属性。
