Question

当我使用url "http:\\localhost\Webservice.asmx"访问服务时，我编写了webservice来向我的数据库插入数据和webservice。如果我使用jquery ajax调用相同的url，它返回（500）内部服务器。这是我的源代码。

//插入客户详细信息的代码

$('#submitAddDetail').on('click', function (e) {

        //alert('Hello World');
        var custId = $(".addcustomer-body #custId").val();
        var custName = $(".addcustomer-body #custName").val();
        var custCity = $(".addcustomer-body #custCity").val();
        var custPostalCode = $(".addcustomer-body #custPostalCode").val();
        var custCountry = $(".addcustomer-body #custCountry").val();
        var custPhone = $(".addcustomer-body #custPhone").val();
        var custFax = $(".addcustomer-body #custFax").val();
        debugger;
        //alert(custName);
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            url: "WebService.asmx/AddCustomers",
            data: "{ 'sCustomerId': '" + custId + "','sCompanyName': '" + custName + "','sCity':'" + custCity + "','sPostalCode':'" + custPostalCode + "','sCountry':'" + custCountry + "','sPhone:'" + custPhone + "','sFax':'" + custFax + "'}",                
            success: function (data) {
                debugger;
                if (data.d == 'true') {
                    location.reload();
                }
                else {
                    debugger;
                    alert('Error in Inserting data');
                }
            }
        });
    });

//我的Web服务插入客户数据。 [的WebMethod]

 public string AddCustomers(string sCustomerId, string sCompanyName, string sCity, string sPostalCode, string sCountry, string sPhone, string sFax)
    {
        string msg = string.Empty;
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (SqlConnection con = new SqlConnection(constr))
        {
            string sQuery = "INSERT INTO Customers (CustomerID,CompanyName,City,PostalCode,Country,Phone,Fax)VALUES" +
                            "(@CustomerID,@CompanyName,@City,@PostalCode,@Country,@Phone,@Fax)";
            using (SqlCommand cmd = new SqlCommand(sQuery))
            {
                cmd.Connection = con;
                cmd.Parameters.AddWithValue("@CustomerID", sCustomerId);
                cmd.Parameters.AddWithValue("@CompanyName", sCompanyName);
                cmd.Parameters.AddWithValue("@City", sCity);
                cmd.Parameters.AddWithValue("@PostalCode", sPostalCode);
                cmd.Parameters.AddWithValue("@Country", sCountry);
                cmd.Parameters.AddWithValue("@Phone", sPhone);
                cmd.Parameters.AddWithValue("@Fax", sFax);
                con.Open();
                int i = cmd.ExecuteNonQuery();
                if (i == 1)
                {
                    msg = "true";
                }
                else
                {
                    msg = "false";
                }
            }
        }
        return msg;
    }//End

我需要你的帮助来解决这个问题。谢谢。

我在Jquery语法中更改了一行并且它有效。

data：'{“sCustomerId”：“'+ custId +'”，“sCompanyName”：“'+ custName +'”，“sCity”：“'+ custCity +'”，“sPostalCode”：“'+ custPostalCode +'“，”sCountry“：”'+ custCountry +'“，”sPhone“：”'+ custPhone +'“，”sFax“：”'+ custFax +'“}'，

感谢。

使用jquery调用Web服务会返回500内部服务器错误？
