ASP.NET通过WebMethod返回JSON对象 [英] ASP.NET return JSON object via WebMethod

问题描述

我有ASP.NET代码

I have ASP.NET code

public class OrderInformationResponse
{
    public GetOrderLookupResponseType orderLookupResponse { get; set; }
}
[System.Web.Services.WebMethod]
public static OrderInformationResponse GetOrderInformation(string jobId, string userId, string jobDetails) {
    OrderInformationResponse response = new OrderInformationResponse();
    JobDetails jobDetailsEnum = (JobDetails)Enum.Parse(typeof(JobDetails), jobDetails);
    response.orderLookupResponse = GetOrderLookup(jobId, userId);
    return response;
}

我尝试用jQuery调用它：

I try calling this from jQuery with:

$.ajax({
            type: "POST",
            url: "somePage.aspx/GetOrderInformation",
            data: "{'jobId':" + jobId + ", " + 
            " 'userId':" + userId + ", " +
                  " 'jobDetails':" + jobDetails +
                  "}",
            contentType: "application/json; charset=utf-8",
            datatype: "json",
            async: true,
            cache: false,
            success: function (msg) {
                p_Func(msg);           // This is a pointer to function.
            }
        });

声明 GetOrderLookupResponseType ：

[System.CodeDom.Compiler.GeneratedCodeAttribute("svcutil", "4.0.30319.17929")] 
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]   [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://schemas.somewhere.uk/MessageContracts/OrderManagement/OrderInfo/2010/02")]
public partial class GetOrderLookupResponseType { ... }

我无法在客户端获得任何东西。在此之前，我试图从标记为 [WebMethod] 的另一个方法返回 GetOrderLookupResponseType 并且它有效，但是当我尝试把它放在一个新创建的 OrderInformationResponse 它停止工作。 （我打算用其他东西填充 OrderInformationResponse ，这就是为什么我没有使用有效的方法）。

I can't get anything on client side. Before this I was trying to return GetOrderLookupResponseType from another method marked [WebMethod] and it worked, but when I tried to put it in a newly created OrderInformationResponse it stopped working. (I plan to fill OrderInformationResponse with additional stuff, that's why I'm not using the method that worked).

推荐答案

我收到HTTP错误500。 jobDetails 以字符串形式发送，但我没有在其周围添加任何引号。

I was getting HTTP Error 500 . jobDetails is sent as a string, but I didn't put any quotes around it.
