一个php创建webservice，并通过c#调用的真实实例

最近需要用php创建webservice供C#和JAVA来调用，通过3天的搜索和尝试，终于成功在C#下调用，JAVA的调用还没开始，为防止忘记，在这里记录下来全过程。

本文参考了许多文章，文中也采用了其中的示例。

本文目录如下

一、php创建webservice

二、生成.wsdl文件

三、c#调用php的webservice

一、php创建webservice

1、php环境

我用的是windows的apache，php.ini文件中 extension=php_soap.dll 去掉注释即可，前提是已经安装了 php_soap.dll。

环境测试，在cmd窗口中输入如下命令来检测soap是否正常

c:\>php --ini　　　　;用来查看ini文件中的soap模块是否正常，它和phpinfo()看到的未必一致

c:\>php -i |findstr "soap"　　;用来看soap模块是否正常

c:\>php -r "new SoapClient('http://localhost/wsdl/person.wsdl');"　　;用来直接运行soap

2、php服务端文件（TestWebService.php）

<span>php  
</span><span>class</span><span> TestWebService  
{  
    </span><span>public</span><span>function</span><span> HelloWorld()  
    {  
        </span><span>return</span><span>array</span>("HelloWorldResult"=>"welcome to dongzi world"<span>);  
    }  
 
    </span><span>public</span><span>function</span> GetArray(<span>$args</span><span>)  
        {  
          </span><span>/*</span><span>
           注意，Web Service的方法在声明时至多一个参数，  
            可是在调用该方法时就必须传value1,value2两个参数。  
            (这一点十分令人费解，我的理解是，在调用该方法时，系统把所有参数都放到一个<strong>对象</strong>里传过来的)  
          </span><span>*/</span><span>$value1</span> = <span>$args</span>-><span>value1;    
        </span><span>$value2</span> = <span>$args</span>->value2;<span>//</span><span>这两句是获取真正的参数  </span><span>$arry</span> = <span>array</span>(<span>$value1</span>,<span>$value2</span><span>);  
 
        </span><span>//</span><span>返回值也很特别，不是直接返回$arry，而是把它放到一个<strong>对象</strong>里再返回。  </span><span>return</span><span>array</span>("GetArrayResult"=><span>$arry</span><span>);  
    }  
}  
</span><span>//</span><span>创建WebSevice实例  </span><span>$server</span> = <span>new</span> SoapServer("TestWebService.wsdl"<span>);  
</span><span>//</span><span>指定类名  </span><span>$server</span>->setClass("TestWebService"<span>);  
</span><span>$server</span>-><span>handle();  
</span>?>

二、生成.wsdl文件

本来我想简单一点，用SoapDiscovery.class.php来生成，可是总是出现各种奇葩问题；迫不得已安装了Zend Studio12.5，可是还是出现另外的奇葩问题；最终我找到一个可行的方案，是用vs2010来生成，C#调用没有问题。

1、打开vs2010，新建项目-ASP.NET空Web应用程序；

2、解决方案资源管理器-项目（右键）-添加-新建项-web服务，名称修改为TestWebService.asmx，代码如下：

<span>using</span><span> System;
</span><span>using</span><span> System.Collections.Generic;
</span><span>using</span><span> System.Linq;
</span><span>using</span><span> System.Web;
</span><span>using</span><span> System.Web.Services;

</span><span>namespace</span><span> Web<strong>Application</strong>1
{
    </span><span>///</span><span><summary></summary></span><span>///</span><span> TestWebService 的摘要说明
    </span><span>///</span><span></span>    [WebService(Namespace = <span>"</span><span>http://tempuri.org/</span><span>"</span><span>)]
    [WebServiceBinding(ConformsTo </span>=<span> WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(</span><span>false</span><span>)]
    </span><span>//</span><span> 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
    </span><span>//</span><span> [System.Web.Script.Services.ScriptService]</span><span>public</span><span>class</span><span> TestWebService : System.Web.Services.WebService
    {

        [WebMethod]
        </span><span>public</span><span>string</span><span> HelloWorld()
        {
            </span><span>return</span><span>""</span><span>;
        }

        [WebMethod]
        </span><span>public</span><span>string</span>[] GetArray(<span>string</span> a,<span>string</span><span> b)
        {
            </span><span>return</span><span>null</span><span>;
        }
    }
}</span>

View Code

HelloWorld()和GetArray()是我们希望暴露的方法，我写成空方法了。

3、F5运行，在弹出的IE浏览器中复制运行的url地址

http://localhost:63463/TestWebService.asmx

打开一个新的IE浏览器窗口，粘贴并修改为，然后回车，此时窗口会展示wsdl文件的xml格式内容：

http://localhost:63463/TestWebService.asmx?wsdl

4、点击IE浏览器的文件-另存为菜单，保存为TestWebService.wsdl文件，放到和TestWebService.php同目录下。

代码如下：

把 http://localhost:63463/TestWebService.asmx 修改为你最终要访问的网址，我的是：

http://192.168.1.5/wsdl/006/TestWebService.php

三、c#调用php的webservice

1、新建网站-ASP.NET网站；

2、解决方案资源管理器-项目（右键）-添加Web引用，在URL中输入：

http://192.168.1.5/wsdl/006/TestWebService.php?wsdl

会显示出如下窗口：

点击[添加引用]

3、修改Default.aspx.cs代码为：

<span>using</span><span> System;
</span><span>using</span><span> System.Collections.Generic;
</span><span>using</span><span> System.Linq;
</span><span>using</span><span> System.Web;
</span><span>using</span><span> System.Web.UI;
</span><span>using</span><span> System.Web.UI.WebControls;

</span><span>public</span><span>partial</span><span>class</span><span> _Default : System.Web.UI.Page
{
    </span><span>protected</span><span>void</span> Page_Load(<span>object</span><span> sender, EventArgs e)
    {
        </span><span>//</span><span>初始化WebService  </span>        WebReference.TestWebService srv = <span>new</span><span> WebReference.TestWebService();
        </span><span>//</span><span>调第一个方法  </span><span>string</span> str =<span> srv.HelloWorld();
        </span><span>//</span><span>调第二个方法  </span><span>string</span>[] arry = srv.GetArray(<span>"</span><span>string1</span><span>"</span>, <span>"</span><span>string2</span><span>"</span><span>);
        Response.Write(str);
    }
}</span>

4、CTRL+F5运行，看到最上面出现“welcome to dongzi world”，表示成功调用！

 

以上就介绍了一个php创建webservice，并通过c#调用的真实实例，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
