菜刀Customize类型服务端asmx版

作者:RedFree

前些天刚学了点ASP.NET的知识，怕学的东西忘了，于是趁热打铁，顺道看了下WebService。WebService这东西以前没有接触过，比较陌生，一点点的搜索，勉勉强强完成了菜刀Customize类型服务端的asmx版。若有错误还请看官指出。
    和其它类型的服务端一样，要完成和服务端的交互，必须具备这两点：1、可以获取参数 2、可以返回内容。于是就从这两个最基本的点入手。
    VS2012新建一个网站，如下图设置：

  可以看到，设置完毕后VS已经生成好了一部分代码。
    按F5键调试一下看看吧：

 点击一下HelloWorld，页面中已经给出了请求和响应的示例：

由于菜刀使用的是HTTP POST协议，所以SOAP请求是用不上了，点击下调用按钮看看吧：

 返回了XML，string标签中包含了代码中返回的"Hello World"。
那么如何获取参数呢？
    尝试改写代码如下：

 出现了错误，经过好一番搜索，得到了解决方法（基础知识太差，这点小问题都耗费了我非常多的时间）。

using System; using System.Collections.Generic; using System.Web; using System.Web.Services;  [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]  public class Service : System.Web.Services.WebService {     public Service () {          //如果使用设计的组件，请取消注释以下行         //InitializeComponent();     }      [WebMethod]     public string HelloWorld() {         String Z = HttpContext.Current.Request.Form["z"];         return Z;     }      }

  终于得到了理想的效果：

 既然可以获得参数又可以返回结果，把菜刀自带Customize.aspx的代码拿来修改下看看是什么效果。

return 执行结果，浏览器中请求下看效果：

看起来结果似乎是让我满意的，然而当我使用菜刀连接的时候却成了这样：

查看网页源码：

  我去，一些字符被转义了。。。通过：http://www.cnblogs.com/qiantuwuliang/archive/2010/03/29/1699361.html得知可以使用CDATA来解决转义的问题。
    修改源码如下，浏览器中请求下看效果：

获得到了满意的结果（菜刀获取的是->||<-之间的内容，其它的字符不会影响结果的）。当然直接

HttpContext.Current.Response.Write("/x2D/x3E/x7C" + R + "/x7C/x3C/x2D");

也是可行的，虽然会报出XML错误，但不影响执行效果（完美主义者不可选）。
    将cs文件是的代码写到asmx文件中去，最终获得asmx后缀的服务端：
