一個php建立webservice，並透過c#呼叫的真實實例

最近需要用php創建webservice供C#和JAVA來調用，透過3天的搜尋和嘗試，終於成功在C#下調用，JAVA的調用還沒開始，為防止忘記，在這裡記錄下來全過程。

本文參考了許多文章，文中也採用了其中的範例。

本文目錄如下

一、php建立webservice

二、產生.wsdl檔案

三、c#調用php的webservice

、創建環境我用的是windows的apache，php.ini檔案中extension=php_soap.dll 去掉註解即可，前提是已經安裝了php_soap.dll。

環境測試，在cmd視窗中輸入如下命令來檢測soap是否正常

c:>php --ini　　　　;用來查看ini檔案中的soap模組是否正常，它和phpinfo()看到的未必一致

c:>php -i |findstr "soap"　　;用來看soap模組是否正常

c:>php -r "new SoapClient('http://localhost/wsdl/person.wsdl');"　　;用用來直接運行soap

2、php服務端檔案（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、生成想php來生成，可是總是出現各種奇葩問題；迫不得已安裝了Zend Studio12.5，可是還是出現另外的奇葩問題；最終我找到一個可行的方案，是用vs2010來生成，C#調用沒有問題。

1、開啟vs2010，新專案-ASP.NET空Web應用程式；2、解決方案資源管理器

-專案（右鍵）-新增-新建項目-web服務，名稱修改為TestWebService.asmx，程式碼如下：

<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()是我們希望暴露的方法，我寫成空方法了。

3、F5運行，在彈出的IE瀏覽器中複製運行的url位址http://localhost:63463/TestWebService.asmx

打開一個新的IE瀏覽器窗口，貼上並修改為，然後回車，此時視窗會展示wsdl檔案的xml格式內容：

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

4、點擊IE瀏覽器的檔案-另存為選單，儲存為TestWebService. wsdl文件，放到和TestWebService.php同目錄下。

代碼如下：

把 http://localhost:63463/TestWebService.asmx 修改為你最終要訪問的網址，我的是1.5/wsdl/006/TestWebService.php

三、c#呼叫php的webservice

1、新網站-ASP.NET網站；2、解決方案資源管理器

-專案新增器

-專案（右鍵）- Web引用，在URL中輸入：

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

會顯示如下視窗：

點擊[新增引用] Default.aspx.cs程式碼為：

<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運行，看到最上面出現“welcome to dongzi world”，表示成功調用！

 

以上就介紹了一個php建立webservice，並透過c#呼叫的真實實例，包含了面向的內容，希望對PHP教學有興趣的朋友有幫助。
