Phonegap Ajax調用返回內部服務器錯誤

我是Phonegap Android應用程序開發的新手。我試圖將我的應用程序與遠程MS SQL Server數據庫連接起來，我寫了一個ASP.Net Web服務來連接這兩個。但是當我通過JQuery ajax（）方法調用這個Web服務時，它返回「Internal Server Error」。Phonegap Ajax調用返回內部服務器錯誤

代碼：

<html> 
<head> 
    <title>PhoneGap Example</title> 
    <script type="text/javascript" charset="utf-8" src="js/cordova.js"></script> 
    <link rel="stylesheet" href="css/jquery.mobile.css" /> 
    <script type="text/javascript" src="js/jquery.js"></script> 
    <script type="text/javascript" src="js/jquery.mobile.js"></script> 
    <script type="text/javascript" > 
     function button_clicked(){ 
      var name = $.trim($("#txtName").val()); 
      var contact = $.trim($("#txtContactNumber").val()); 
      var type = $.trim($("#txtType").val()); 

      if(name.length > 0) 
      { 
       $.ajax({ 
        type: "POST", 
        url: "http://my-domain.com/DocNote_WebService/DoctorMaster.asmx/insertDoctor", 
        data: "{doctorName: "+ name + ",contactNumber: "+ contact + ",doctorType: " + type +"}", 
        contentType: "application/json; charset=utf-8", 
        dataType: "json", 
        success : function(data) {    
         alert('Record Saved Sucessfully.....!!!!'); 
        }, 
        error: function(xhr, ajaxOptions, thrownError) { 
         alert('ERROR: '+thrownError); 
        } 
       }); 
      } 
     } 
    </script> 
</head> 
<body> 
    <section id="page1"> 
     <header><h1>DocNote</h1></header> 
     <div class="content" data-role="content"> 
      <h3>Enter Doctor Info</h3> 

       <div data-role="fieldcontain"> 
        <input type="text" data-clear-btn="true" name="txtName" id="txtName" placeholder="Enter Name"/> 
        <br/> 
        <input type="text" data-clear-btn="true" name="txtContactNumber" id="txtContactNumber" placeholder="Contact Number"/> 
        <br/> 
        <input type="text" data-clear-btn="true" name="txtType" id="txtType" placeholder="Type"/> 
        <br/> 
        <button id="btnSubmit" class="ui-btn ui-btn-inline ui-corner-all" onclick="button_clicked()">Submit</button> 
        <button id="btnCancel" class="ui-btn ui-btn-inline ui-corner-all">Cancel</button> 
       </div> 

     </div> 
    </section> 
</body> 
</html>

我的Web服務方法：

[WebMethod] 
    public void insertDoctor(String doctorName, String contactNumber, int doctorType) { 
     using (SqlConnection connection = ConnectionFactory.getConnection()) 
     { 
      SqlCommand sqlCommand = new SqlCommand("Insert into DOCTOR_MASTER (DOCTOR_NAME, DOCTOR_CONTACT_NUMBER,DOCTOR_TYPE) values (@name,@contact,@type)",connection); 
      sqlCommand.Parameters.AddWithValue("@name", doctorName); 
      sqlCommand.Parameters.AddWithValue("@contact",contactNumber); 
      sqlCommand.Parameters.AddWithValue("@type", doctorType); 

      sqlCommand.ExecuteNonQuery(); 
     } 
    }

告訴我我提前做錯了..... 感謝...... ...

您是否嘗試過調試服務器上的代碼以查看導致錯誤的原因？沒有這個，「內部服務器錯誤」根本沒有任何幫助。 – Archer 2014-10-20 14:30:31

嘗試使用request.form [「keyword」]在服務器端獲取發佈的數據並以這種方式發佈數據： data：{name：name，contact：contact，type：type} – Emre 2014-10-21 07:45:51

@Archer：我測試了我的Web服務使用[測試工具]（https://wizdl.codeplex.com/），並且工作正常。 – 2014-10-21 21:11:10

最後，我發現解決方案Here。

data: "{ firstName: 'Aidy', lastName: 'F' }"

然後，我修改了我的代碼並工作。

$.ajax({ 
     type: "POST", 
     url: "http://my-domain.com/DocNote_WebService/DoctorMaster.asmx/insertDoctor", 
     data: "{doctorName:'" + doctorName + "', contactNumber:'" + contactNumber + "', doctorType:'" + doctorType + "'}", 
     contentType: "application/json; charset=utf-8", 
     dataType: "json", 
     success : function(response) {    
      alert('Record Saved Sucessfully.....!!!!');      
     }, 
     error: function(xhr, ajaxOptions, thrownError) { 
      alert('ERROR: '+thrownError); 
     } 
});

將數據作爲對象傳遞，而不是字符串...

$.ajax({ 
    type: "POST", 
    url: "http://my-domain.com/DocNote_WebService/DoctorMaster.asmx/insertDoctor", 
    data: { 
     "doctorName": name, 
     "contactNumber": contact, 
     "doctorType": type 
    }, 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    success : function(data) {    
     alert('Record Saved Sucessfully.....!!!!'); 
    }, 
    error: function(xhr, ajaxOptions, thrownError) { 
     alert('ERROR: '+thrownError); 
    } 
});
