将C#实体类传递给json-jquery时，HTTPGET失败 [英] HTTPGET fail when passing C# entity class to json-jquery

问题描述

这是我的jquery:

$.ajax({
        type: 'GET',
        url: '/services/Service.asmx/FamilyHistory',
        data: JSON.stringify({
            userID: 10,
            historyID: famid
        }),
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        success: function(val) {
            var famHist = val.d;
            alert(famHist.ID);
        },
        error: function() {
            parent.$.jGrowl('<b>Failed</b>',
                 {
                     header: 'User Action:',
                     life: 3000
                 });
        }
    });

我的班级:

public sealed class FamilyHistoryEntity
{
    public string ID { get; set; }
    public string RelativeName { get; set; }
}

我的Web服务:

    [WebMethod(EnableSession = true)]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = true)]
    public FamilyHistoryEntity FamilyHistory(int userID, string historyID)
    {
         return GetFamilyHistory(historyID, userID); // returns a FamilyHistoryEntity class
    }

问题是，我什至无法使其成为Web服务的断点，它只会引发jquery ajax事件错误.

Problem is, i can't even make it do a breakpoint onto the webservice, it just throws the jquery ajax event of error.

推荐答案

为什么要使用stringify函数?似乎正在寻找使用字符串参数而不是方法具有的两个参数的方法.

Why are you using the stringify function? It would seem like it is looking to call a method with a string parameter rather than the two parameters you have for your method.

也许我错过了什么?

因此，您将data属性更改为:

So you would change the data property to:

data: { userID: 10, historyID: famid },

特别是因为您将contentType指定为json.

Especially since you specify the contentType as json.
