目前为止似乎还没有看到过Web版的普通消息测试工具（除了官方针对高级接口的），现有的一些桌面版的几个测试工具也都是使用XML直接请求，非常不友好，我们来尝试做一个“面向对象”操作的测试工具。
测试工具在线DEMO：http://weixin.senparc.com/SimulateTool
Senparc.Weixin.MP是一个开源的微信SDK项目，地址：https://github.com/JeffreySu/WeiXinMPSDK （其中https://github.com/JeffreySu/WeiXinMPSDK/tree/master/Senparc.Weixin.MP.Sample 包含了本文所讲的所有源代码）
也可以通过Nuget直接安装到项目中：https://www.nuget.org/packages/Senparc.Weixin.MP
Senparc.Weixin.MP教程索引：http://www.cnblogs.com/szw/archive/2013/05/14/weixin-course-index.html
下面大致解释一下源代码及工作原理：
一、界面
界面分为4大区域：接口设置、发送参数、发送内容和接收内容
其中接口设置用于提供类似微信公众账号后台的Url和Token的对接参数设置，指定目标服务器。
在发送参数中，根据选择不同的消息类型，下面的参数选项会对应变化。
发送内容显示的是提交参数之后，模拟发送到目标服务器的XML，这里摆脱了之前一些需要手动输入XML的麻烦。
根据发送内容，在接收内容框中，显示目标服务器返回的实际内容。
二、服务器端代码
由于使用了Senparc.Weixin.MP SDK，所有的XML生成、代理操作、XML流等操作都变得非常简单，一共只用了100多行代码就实现了XML生成及模拟发送、接收等2大块功能，这里为了让大家看得更明白，将所有代码都尽量平铺直叙，实际还可以有很多缩减或重用的地方（文件位于源代码/Senparc.Weixin.MP.Sample/Senparc.Weixin.MP.Sample/Controllers/SimulateToolController.cs）：
using System;
using System.IO;
using System.Web.Mvc;
using System.Xml.Linq;
using Senparc.Weixin.MP.Agent;
using Senparc.Weixin.MP.Entities;
using Senparc.Weixin.MP.Helpers;
namespace Senparc.Weixin.MP.Sample.Controllers
{
public class SimulateToolController : BaseController

};
break;
//case RequestMsgType.Link:

case RequestMsgType.Event:
if (eventType.HasValue)
{
RequestMessageEventBase requestMessageEvent = null;
switch (eventType.Value)
{
//case Event.ENTER:

case Event.LOCATION:
requestMessageEvent = new RequestMessageEvent_Location()
{

break;

}; break;
case Event.VIEW:
requestMessageEvent = new RequestMessageEvent_View()
{

}; break;
case Event.MASSSENDJOBFINISH:

{

default:

}
requestMessaage = requestMessageEvent;
}
else
{

}
break;

}
requestMessaage.CreateTime = DateTime.Now;
requestMessaage.FromUserName = requestMessaage.FromUserName ?? "FromUserName（OpenId）";//用于区别不同的请求用户
requestMessaage.ToUserName = "ToUserName";
return requestMessaage.ConvertEntityToXml();
}

三、View代码
下面是MVC中View（razor）的代码（200行左右，文件位于源代码/Senparc.Weixin.MP.Sample/Senparc.Weixin.MP.Sample/Views/SimulateTool/Index.cshtml）：
1 @{ 2 ViewBag.Title = "微信消息模拟测试工具"; 3 Layout = "~/Views/Shared/_Layout.cshtml"; 4 5 var nonce = "JeffreySu"; 6 var timestamp = DateTime.Now.Ticks.ToString(); 7 var echostr = DateTime.Now.Ticks.ToString(); 8 var token = ViewData["Token"] as string; 9 } 10 @section HeaderContent 11 { 12 <style> 13 .param { 14 display: none; 15 } 16 17 .messageXmlArea { 18 width: 100%; 19 } 20 21 .messageXmlArea textarea { 22 width: 100%;

51 var paramId = 'param' + requestType; 52 $('div[id^=param]').hide(); 53 $('#' + paramId).show(); 54 } 55 56 function checkEventType() { 57 var requestType = $('#eventType').val(); 58 var eventId = 'event' + requestType;

67 var eventType = $('#eventType').val(); 68 var param = { url: url, token: token, requestType: requestType }; 69 var paramId = 'param' + requestType; 70 var eventId = 'event' + eventType; 71 //设置参数 72 if (requestType != 'Event') { 73 $.each($('#' + paramId).find('input'), function (i, item) { 74 param[$(item).attr('name')] = $(item).val(); 75 }); 76 } else { 77 param.eventType = eventType; 78 $.each($('#' + eventId).find('input'), function (i, item) { 79 param[$(item).attr('name')] = $(item).val(); 80 }); 81 } 82 83 var txtResponseMessageXML = $('#responseMessageXML'); 84 var txtRequestMessageXML = $('#requestMessageXML'); 85 86 txtResponseMessageXML.html('载入中...'); 87 txtRequestMessageXML.html('载入中...'); 88 89 $.post('@Url.Action("Index")', param, function (result) { 90 txtResponseMessageXML.html(result); 91 }); 92 93 $.post('@Url.Action("GetRequestMessageXml")', param, function (result) { 94 txtRequestMessageXML.html(result); 95 }); 96 } 97 </script> 98 } 99 @section Featured 100 { 101 102 } 103 <section class="content-wrapper main-content clear-fix"> 104 <h1>消息模拟工具</h1> 105 <div class="clear-fix"></div> 106 <div id="simulateTool"> 107 <div class="paramAreaLeft"> 108 <h3>接口设置</h3> 109 <div> 110 URL：@Html.TextBox("Url", Url.Action("Index", "Weixin", null, "http", Request.Url.Host))<br /> 111 Token：@Html.TextBox("Token", token) 112 </div> 113 <h3>发送参数</h3> 114 <div> 115 类型：<select id="requestType"> 116 <option value="Text">文本</option> 117 <option value="Location">地理位置</option> 118 <option value="Image">图片</option> 119 <option value="Voice">语音</option> 120 <option value="Video">视频</option> 121 @*<option value="Link">连接信息</option>*@ 122 <option value="Event">事件推送</option> 123 </select> 124 </div> 125 <div> 126 参数： 127 <div id="paramText" class="param"> 128 Content：<input name="Content" /> 129 </div> 130 <div id="paramLocation" class="param"> 131 Label：<input name="Label" /><br /> 132 Location_X：<input name="Location_X" type="number" value="0" /><br /> 133 Location_Y：<input name="Location_Y" type="number" value="0" /><br /> 134 Scale：<input name="Scale" type="number" value="0" step="1" /><br /> 135 </div> 136 <div id="paramImage" class="param"> 137 PicUrl：<input name="PicUrl" /><br /> 138 </div> 139 <div id="paramVoice" class="param"> 140 Format：<input name="Format" value="arm" /><br /> 141 Recognition：<input name="Recognition" /><br /> 142 </div> 143 <div id="paramVideo" class="param"> 144 MsgId：<input name="MsgId" type="number" value="@DateTime.Now.Ticks" step="1" /><br /> 145 ThumbMediaId：<input name="ThumbMediaId" /><br /> 146 </div> 147 @*<div id="paramLink" class="param"></div>*@ 148 <div id="paramEvent" class="param"> 149 事件类型：<select id="eventType"> 150 @*<option value="ENTER">进入会话</option>*@ 151 <option value="LOCATION">地理位置</option> 152 <option value="subscribe">订阅</option> 153 <option value="unsubscribe">取消订阅</option> 154 <option value="CLICK">自定义菜单点击事件</option> 155 <option value="scan">二维码扫描</option> 156 <option value="VIEW">URL跳转</option> 157 <option value="MASSSENDJOBFINISH">事件推送群发结果</option> 158 </select> 159 @*<div id="eventENTER" class="param"></div>*@ 160 <div id="eventLOCATION" class="param"> 161 Latitude：<input name="Event.Latitude" type="number" value="0"/><br /> 162 Longitude：<input name="Event.Longitude" type="number" value="0"/><br /> 163 Precision：<input name="Event.Precision" type="number" value="0"/><br /> 164 </div> 165 <div id="eventsubscribe" class="param"> 166 EventKey：<input name="Event.EventKey" /><br /> 167 </div> 168 <div id="eventunsubscribe" class="param"></div> 169 <div id="eventCLICK" class="param"> 170 EventKey：<input name="Event.EventKey" /><br /> 171 </div> 172 <div id="eventscan" class="param"> 173 EventKey：<input name="Event.EventKey" /><br /> 174 Ticket：<input name="Event.Ticket" /><br /> 175 </div> 176 <div id="eventVIEW" class="param"> 177 EventKey：<input name="Event.EventKey" value="http://" /><br /> 178 </div> 179 <div id="eventMASSSENDJOBFINISH" class="param"> 180 ErrorCount：<input name="Event.ErrorCount" type="number" value="0"/><br /> 181 FilterCount：<input name="Event.FilterCount" type="number" value="0"/><br /> 182 SendCount：<input name="Event.SendCount" type="number" value="0"/><br /> 183 Status：<input name="Event.Status"/><br /> 184 TotalCount：<input name="Event.TotalCount" type="number" value="0"/><br /> 185 </div> 186 </div> 187 <div> 188 <input type="button" value="提交" onclick="sendMessage()" /> 189 </div> 190 </div> 191 </div> 192 <div class="paramArearight"> 193 194 <div class="messageXmlArea"> 195 <h3>发送内容（根据参数自动生成）</h3> 196 <textarea id="requestMessageXML" readonly="readonly"></textarea> 197 </div> 198 <div class="messageXmlArea"> 199 <h3>接收内容</h3> 200 <textarea id="responseMessageXML"></textarea> 201 </div> 202 </div> 203 </div> 204 </section>
