我執行下面的代碼:用Sharepoint Rest API創建列表項;結果是400錯誤的請求

結果是:
A távoli kiszolgáló a következő hibát küldte vissza: (400) Hibás kérelem.
{"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"hu-HU","value":"Invalid JSON. The property name '' is not valid. The name of a property cannot be empty."}}}
英語匈牙利文: 遠程服務器返回錯誤:(400)錯誤的請求。
我不想忽略哪個屬性是空的。如果第一個和最後一個字符的內容不是{和},那麼錯誤是「無效的JSON。JSON內容中沒有識別出令牌。」 如果內容爲空{}或{},則誤差同上(屬性名稱「」是無效的。......「)
你能幫我嗎? 感謝
之間任何其他字符串
不幸的是,這是不行的,拋出一個延伸: 類型的未處理的異常「System.Net .ProtocolViolationException'發生在System.dll中 此異常是因爲此代碼未設置httpWebRequest.ContentLength屬性。 –
它返回什麼樣的錯誤,它適用於我 –
@LászlóH。發生此錯誤的原因是,在刪除行'httpWebRequest.ContentLength = 0;'後,請求體長顯式設置爲0,錯誤應該消失。 –
