调用Web服务的.asmx使用AJAX

我已经实现在一个asp.net web应用程序，它允许用户选择的东西，并产生一个电子邮件模板弹出的JavaScript。完成所有必填字段后，用户通过单击按钮发送电子邮件。调用Web服务的.asmx使用AJAX

此按钮调用JavaScript函数，我收集所有喜欢从，到，主题，正文用户输入数据，并希望将此数据发送到我创建了一个Web服务将发送邮件。

我不想用邮寄地址，所以我与web服务去了。

的问题是，我不能发送数据：

$.ajax({ 
      type: 'POST', 
      url: "Services/MailService.asmx/SendMail", 
      dataType: "json", 
      contentType: 'application/json; charset=utf-8', 
      data: { 'loginName': "'" + loginName + "'", 'fromAddress': "'" + fromAddress + "'", 'toAddress': "'" + toAddress + "'", 'mailSubject': "'" + mailSubject + "'", 'mailBody': "'" + mailBody + "'"}, 
      success: function() 
      { 
       alert("The email was sent successfully!"); 
      }, 
      error: function(data) 
      { 
       alert("An error occurred while trying to send the email. " + data.responseText); 
      } 
     });

我知道，我在插入数据属性是错误的。我曾尝试以下，（一次一个）：

data: JSON.stringify({ 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody }), 
data: { 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody }, 
data: { loginName: loginName, fromAddress: fromAddress, toAddress: toAddress, mailSubject: mailSubject, mailBody: mailBody }, 
data: "{ 'loginName': '" + loginName + "', 'fromAddress': '" + fromAddress + "', 'toAddress': '" + toAddress + "', 'maliSubject': '" + mailSubject + "', 'mailBody': '" + mailBody + "' }",

所有这些选项给我下面的错误：

An error occurred while trying to send the email. {"Message":"Invalid web service call, missing value for parameter: \u0027mailBbody\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

或

An error occurred while trying to send the email. {"Message":"Invalid JSON primitive: loginName.","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject()\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

我不明白是什么我做错了。

Web服务是这样的：

[System.Web.Script.Services.ScriptService] 
public class WebService1 : System.Web.Services.WebService 
{ 
    [WebMethod] 
    public void SendMail(string loginName, string fromAddress, string toAddress, string mailSubject, string mailBody) 
    { 
     MailMessage mailMsg = new MailMessage(fromAddress, toAddress); 
     mailMsg.Subject = mailSubject; 
     mailMsg.Body = mailBody; 

     string pathToCreate = "~/Upload/" + loginName + "/"; 
     if (Directory.Exists(Server.MapPath(pathToCreate))) 
     { 
      if (Directory.GetFiles(Server.MapPath(pathToCreate)).Length > 0) 
      { 
       string[] attachedFiles = Directory.GetFiles(Server.MapPath(pathToCreate)); 
       foreach (string a in attachedFiles) 
       { 
        Attachment data = new Attachment(a); 
        mailMsg.Attachments.Add(data); 
       } 
      } 
     } 

     SmtpClient smtp = new SmtpClient(); 
     smtp.Send(mailMsg); 
    } 
}

请与我分享我还能有什么办法来解决这个问题。

谢谢！

我能够通过成功地发送数据：

data: '{loginName:' + JSON.stringify(loginName) + ', fromAddress:' + JSON.stringify(fromAddress) + ', toAddress:' + JSON.stringify(toAddress) + ', mailSubject:' + JSON.stringify(mailSubject) + ', mailBody:' + JSON.stringify(mailBody) + '}',

我不知道这是正确的方式，但它的工作。
