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）：

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%;
