我需要創建一個WCF服務以從C#中的SQL數據庫中檢索數據,並使用JSON在HTML5中使用該WCF服務。在HTML頁面中調用WCF服務時出錯
我創建了WCF服務及其工作,但是當我嘗試在HTML中使用它時,它顯示「對象對象錯誤(無法加載資源:服務器響應的狀態爲415(無法處理消息,因爲內容類型'應用/ JSON的;字符集= UTF-8' 是不是預期的類型 '文本/ XML的,字符集= utf-8')」
幫我解決這個

我也嘗試通過把POST而不是GET,仍顯示**對象對象錯誤無法加載資源:服務器響應狀態415(無法處理消息,因爲內容類型'application/json'是而不是期望的類型'text/xml; charset = utf-8'。)* 幫助我如何解決此問題 – Sathiya 2014-09-11 09:48:06
