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
{
/// <summary>

private XDocument GetrequestMessaageDoc(string url,string token,RequestMsgType requestType,Event? eventType)
{
RequestMessageBase requestMessaage = null;
switch (requestType)
{
case RequestMsgType.Text:
requestMessaage = new RequestMessageText()
{
Content = Request.Form["Content"],};
break;
case RequestMsgType.Location:
requestMessaage = new RequestMessageLocation()
{

requestMessaage = new RequestMessageImage()
{
PicUrl = Request.Form["PicUrl"],};
break;
case RequestMsgType.Voice:
requestMessaage = new RequestMessageVoice()
{
Format = Request.Form["Format"],Recognition = Request.Form["Recognition"],};
break;
case RequestMsgType.Video:
requestMessaage = new RequestMessageVideo()
{
MsgId = long.Parse(Request.Form["MsgId"]),ThumbMediaId = Request.Form["ThumbMediaId"],};
break;
//case RequestMsgType.Link:
// break;
case RequestMsgType.Event:
if (eventType.HasValue)
{
RequestMessageEventBase requestMessageEvent = null;
switch (eventType.Value)
{
//case Event.ENTER:
// break;
case Event.LOCATION:
requestMessageEvent = new RequestMessageEvent_Location()
{
Latitude = long.Parse(Request.Form["Event.Latitude"]),Longitude = long.Parse(Request.Form["Event.Longitude"]),Precision = double.Parse(Request.Form["Event.Precision"])
};
break;
case Event.subscribe:
requestMessageEvent = new RequestMessageEvent_Subscribe()

break;

break;

{
EventKey = Request.Form["Event.EventKey"]
};
break;
case Event.scan:
requestMessageEvent = new RequestMessageEvent_Scan()
{
EventKey = Request.Form["Event.EventKey"],Ticket = Request.Form["Event.Ticket"]
}; break;
case Event.VIEW:
requestMessageEvent = new RequestMessageEvent_View()
{
EventKey = Request.Form["Event.EventKey"]
}; break;
case Event.MASSSENDJOBFINISH:
requestMessageEvent = new RequestMessageEvent_MassSendJobFinish()
{
FromUserName = "mphelper",//系统指定
ErrorCount = int.Parse(Request.Form["Event.ErrorCount"]),FilterCount = int.Parse(Request.Form["Event.FilterCount"]),SendCount = int.Parse(Request.Form["Event.SendCount"]),Status = Request.Form["Event.Status"],TotalCount = int.Parse(Request.Form["Event.TotalCount"])
}; break;
default:
throw new ArgumentOutOfRangeException("eventType");
}
requestMessaage = requestMessageEvent;
}
else
{
throw new ArgumentOutOfRangeException("eventType");
}
break;
default:
throw new ArgumentOutOfRangeException("requestType");
}
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();
}
/// <summary>

public ActionResult Index()
{

}

[HttpPost]
public ActionResult Index(string url,Event? eventType)
{
using (MemoryStream ms = new MemoryStream())
{
var requestMessaageDoc = GetrequestMessaageDoc(url,token,requestType,eventType);
requestMessaageDoc.Save(ms);
ms.Seek(0,SeekOrigin.Begin);
var responseMessageXml = MessageAgent.RequestXml(null,url,requestMessaageDoc.ToString());
return Content(responseMessageXml);
}
}

}
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 23 height 200px 24 25 26 .paramAreaLeft 27 float left 28 45% 29 margin-right 6% 30 31 32 .paramArearight 33 34 35 36 37 #requestType,#eventType 38 padding 5px 39 40 </ 41 script 42 $(function () { 43 $('#requestType).change(checkRequestType); 44 #eventType).change(checkEventType); 45 checkRequestType(); 46 checkEventType(); 47 }); 48 49 checkRequestType() { 50 var requestType = $().val(); 51 paramId = param' + requestType; 52 div[id^=param]).hide(); 53 # paramId).show(); 54 } 55 56 checkEventType() { 57 58 eventId event 59 div[id^=event] 60 eventId).show(); 61 62 63 sendMessage() { 64 url #Url 65 token #Token 66 67 eventType 68 param { url: url,token: token,requestType: requestType }; 69 70 eventType; 71 //设置参数 72 if (requestType != Event) { 73 $.each($( paramId).find(input), (i,item) { 74 param[$(item).attr(name)] $(item).val(); 75 }); 76 } else { 77 param.eventType 78 eventId).find( 79 80 81 } 82 83 txtResponseMessageXML #responseMessageXML); 84 txtRequestMessageXML #requestMessageXML 85 86 txtResponseMessageXML.html(载入中... 87 txtRequestMessageXML.html( 88 89 $.post(@Url.Action("Index"),param,1)"> (result) { 90 txtResponseMessageXML.html(result); 91 }); 92 93 @Url.Action("GetRequestMessageXml") 94 txtRequestMessageXML.html(result); 95 96 97 98 99 @section Featured 100 101 102 103 section class="content-wrapper main-content clear-fix"104 h1>消息模拟工具105 div ="clear-fix"></div106 id="simulateTool"107 ="paramAreaLeft"108 h3>接口设置109 110 URL：@Html.TextBox("Url",Url.Action("Index","Weixin",null,"http",Request.Url.Host))br /> 111 Token：@Html.TextBox("Token",token) 112 113 >发送参数114 115 类型：select ="requestType"116 option value="Text">文本option117 ="Location">地理位置118 ="Image">图片119 ="Voice">语音120 ="Video">视频121 @*="Link">连接信息>*@ 122 ="Event">事件推送123 select124 125 126 参数： 127 ="paramText" class="param"128 Content：input name="Content" 129 130 ="paramLocation"131 Label：="Label" /><132 Location_X：="Location_X" type="number" value="0" 133 Location_Y：="Location_Y"134 Scale：="Scale"="0" step="1" 135 136 ="paramImage"137 PicUrl：="PicUrl" 138 139 ="paramVoice"140 Format：="Format"="arm" 141 Recognition：="Recognition" 142 143 ="paramVideo"144 MsgId：="MsgId"="@DateTime.Now.Ticks"145 ThumbMediaId：="ThumbMediaId" 146 147 @*="paramLink"148 ="paramEvent"149 事件类型：="eventType"150 @*="ENTER">进入会话151 ="LOCATION"152 ="subscribe">订阅153 ="unsubscribe">取消订阅154 ="CLICK">自定义菜单点击事件155 ="scan">二维码扫描156 ="VIEW">URL跳转157 ="MASSSENDJOBFINISH">事件推送群发结果158 159 @*="eventENTER"160 ="eventLOCATION"161 Latitude：="Event.Latitude"="0"162 Longitude：="Event.Longitude"163 Precision：="Event.Precision"164 165 ="eventsubscribe"166 EventKey：="Event.EventKey" 167 168 ="eventunsubscribe"169 ="eventCLICK"170 EventKey：171 172 ="eventscan"173 EventKey：174 Ticket：="Event.Ticket" 175 176 ="eventVIEW"177 EventKey：="Event.EventKey"="http://" 178 179 ="eventMASSSENDJOBFINISH"180 ErrorCount：="Event.ErrorCount"181 FilterCount：="Event.FilterCount"182 SendCount：="Event.SendCount"183 Status：="Event.Status"184 TotalCount：="Event.TotalCount"185 186 187 188 type="button"="提交" onclick="sendMessage()" 189 190 191 192 ="paramArearight"193 194 ="messageXmlArea"195 >发送内容（根据参数自动生成）196 textarea ="requestMessageXML" readonly="readonly"textarea197 198 199 >接收内容200 ="responseMessageXML"201 202 203 204 section>
