使用json / jquery将更长的字符串发布到Web服务 [英] Post a longer string to a webservice using json/jquery

问题描述

我向Webservice发送的数据很少。

=============================== ====

I am sending few data to Webservice.
===================================

function test() {
        var dataURL = "data:image/png;base64,iVBORw0KGgoAAAAN";
        var dataUrlJson = [{ "imageData": dataURL }];       
        $.ajax({
            type: "POST",
            url: "LP18WS.asmx/CreateMarkers",
            // The key needs to match your method's input parameter (case-sensitive).
            data: JSON.stringify({ Markers: dataUrlJson }),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) { alert(data); },
            failure: function (errMsg) {
                alert(errMsg);
            }
        });

==== === ====================================
LP18WS.asmx文件中的
< br $>
==================

===========================================
in LP18WS.asmx file
==================

public class Marker
        {
            string imageData { get; set; }            
        }
        

        [WebMethod]
        public string CreateMarkers(List<Marker> Markers)
        {
            foreach (Marker mk in Markers)
            {
              //string aa = mk.imageData//Error
            }

            return "Received " + Markers.Count + " markers.";
        }

============================== ==============

调试器正在执行而没有任何错误。



但我是无法读取数据。

任何人都可以告诉我如何读取数据（即标记[imageData]）

============================================
Debugger is hitting and executing without any error.

But I am not able to read the data.
Can anyone tell me how to read the data (ie. Markers["imageData "])

推荐答案

.ajax（{
type： POST，
url：< span class =code-string> LP18WS.asmx / CreateMarkers，
/ / 密钥需要匹配方法的输入参数（区分大小写）。
data： JSON .stringify（{Markers：dataUrlJson}），
contentType： application / json; charset = utf-8，
dataType： json，
成功： function （data）{alert（data）; }，
失败： function （errMsg）{
alert（errMsg）;
}
}）;

.ajax({ type: "POST", url: "LP18WS.asmx/CreateMarkers", // The key needs to match your method's input parameter (case-sensitive). data: JSON.stringify({ Markers: dataUrlJson }), contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { alert(data); }, failure: function (errMsg) { alert(errMsg); } });
