下面的代碼適用於大多數的學生在教室裏時,他們提交asignment調用返回400錯誤,但它拋出一個400錯誤的異常對一些學生:ModifyAttachments使用C#客戶端庫
var classroom = GetClassroomService();
var studentSubmissionsResponse = classroom.Courses.CourseWork.StudentSubmissions.List(courseId, courseWorkId).Execute();
var submission = studentSubmissionsResponse.StudentSubmissions.FirstOrDefault(s => s.AssociatedWithDeveloper ?? false);
var modifyAttachmentRequest = new global::Google.Apis.Classroom.v1.Data.ModifyAttachmentsRequest();
var link = new global::Google.Apis.Classroom.v1.Data.Link() { Url = url };
var attachment = new global::Google.Apis.Classroom.v1.Data.Attachment() { Link = link };
modifyAttachmentRequest.AddAttachments = new System.Collections.Generic.List<global::Google.Apis.Classroom.v1.Data.Attachment>();
modifyAttachmentRequest.AddAttachments.Add(attachment);
submission = classroom.Courses.CourseWork.StudentSubmissions.ModifyAttachments(modifyAttachmentRequest, courseId, courseWorkId, submission.Id).Execute();
/// submission code is after this; the exception is thrown by the call above
唯一的例外是:
The service classroom has thrown an exception: Google.GoogleApiException: Google.Apis.Requests.RequestError
Request contains an invalid argument. [400]
Errors [
Message[Request contains an invalid argument.] Location[ - ] Reason[badRequest] Domain[global]
]
不幸的是,C#客戶端庫目前不支持詳細的錯誤信息的顯示呢。
關於可能發生什麼的任何想法?如何解決問題?
我希望我能做到這一點。當學生在(物理)課堂上完成作業時,會拋出異常。該錯誤消息表明存在無效參數。在那個調用中,改變的唯一參數是URL。我嘗試過使用我自己的帳戶失敗的網址,他們的工作。所以,這不是網址。其他學生的課程和課程工作。只留下提交.Id,但我認爲我正確得到提交。 –
