出现问题“服务方法名称无效” [英] Getting issue "Service method name is not valid"

问题描述

大家好，



我无法在下面的案例中找出问题所在。我有一个webmethod并使用jquery ajax调用调用相同的方法。下面是代码。

Hi All,

I couldn't be able to figure out the problem in the below case. I have a webmethod and calling the same using jquery ajax call. Below is the code.

[WebMethod(EnableSession = true)]
    [ScriptMethod()]
    public void SaveSearch(cnt strProp)
    {
    }

其中cnt是班级。



当我使用ajax调用来调用它时。

where cnt is the class.

When i calling this using ajax call like.

var strArray = {
                 cntName : "1",
                 cntEmail : "2",
                 cntMsg : "3"
            }

$.ajax({
               url: '/getproductsservice.asmx/SaveSearch',
               method: 'POST',
               data:  { strProp : strArray},
               contentType: 'application/json; charset=utf-8',
               success: function (data) {
                   var showMsg = ''
                   alert(showMsg);
               },
               error: function (data) {
                   alert('Save Search Failed');
               }
           });

运行时，我得到了一个例外，说明SaveSearch服务方法名称无效。



但是如果我用像string或int这样的原始数据类型替换参数它运行良好。问题在于对象类型（列表或对象等）。



如果我使用原始类型，它仅在ajax内容类型为content /时才有效xml不使用content / json。如果我使用json类型获得另一个例外尝试使用GET请求调用方法\ u0027SaveSearch \ u0027，这不允许
。



请帮忙解决这个问题。

When running this, i got the exception stating that "SaveSearch Service method name is not valid".

But if I replace the parameter with primitive data type like string or int it is working well. Problem is with the object types (list or object etc).

And if I use the primitive type, it is working only if the ajax content type is "content/xml" not working with "content/json". If I use the json type getting another exception of "An attempt was made to call the method \u0027SaveSearch\u0027 using a GET request, which
is not allowed."

Kindly help to resolve this.

推荐答案

.ajax（{
url：' / getproductsservice.asmx / SaveSearch'，
method：' POST'，
data：{strProp：strArray}，
contentType：' application / json; charset = utf-8'，
成功：功能（数据） {
var showMsg = ' '
alert（showMsg）;
}，
错误： function （data）{
alert（' 保存搜索失败）;
}
}）;

.ajax({ url: '/getproductsservice.asmx/SaveSearch', method: 'POST', data: { strProp : strArray}, contentType: 'application/json; charset=utf-8', success: function (data) { var showMsg = '' alert(showMsg); }, error: function (data) { alert('Save Search Failed'); } });
