我在网上做了一些搜索，似乎无法弄清楚这一点。如何强制响应只是 JSON？

网络配置 

<httpHandlers>
            <remove path="*.asmx" verb="*" />
            <add path="*.asmx" verb="*" validate="false"
                 type="System.Web.Script.Services.ScriptHandlerFactory, 
                 System.Web.Extensions, Version=3.5.0.0,
                 Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

</httpHandlers>

function get_data() {            
            var objdata = new Object;
            objdata.tool = '1';
            objdata.product = 'Something';
            objdata.details = '9';
            objdata.bogus = 'should not pass validation';
            var server = 'http://crossdomainserver:87';
            var webMethod = '/LogInfo.asmx/LogInfo?';
            var url = server + webMethod + "tool=" + objdata.tool + "&" +
                "product=" + objdata.product + "&" +
                "details=" + objdata.details + "&" +
                "bogus=" + objdata.bogus;
            $('#url').html("<p>" + url + "</p>");

            $.ajax({
                url: url,
                cache: false,
                dataType: "jsonp",
                contentType: "application/json; charset=utf-8",
                success: function (data) {
                    $('#get').html("<p>" + data + "</p>");
                },
                error: function (e) {

                }
            });


            $('#result').html("<p>" + result.statusText + "</p>");
        }

JSON 是不可能的，.asmx您需要使用WCFWeb 服务以 json 格式返回数据。
