接口无非就是拼接字符串发动到指定的网站

POST 与 Get 一样,改下参数就行

例如:

http://localhost:8080/axis2/services/AAAA/getVerifyCode?args0=abc

返回信息

<ns:getVerifyCodeResponse xmlns:ns="http://wserver">

    <ns:return>C</ns:return>

</ns:getVerifyCodeResponse>

使用方法

 WebServiceHelper webServiceHelper = new WebServiceHelper();

string url="http://localhost:8080/axis2/services/AAAA";

 Hashtable ht = new Hashtable(); //创建一个Hashtable实例                   

//正式库
ht.Add("args0", "abc");

//发送数据
string msg = webServiceHelper.QueryGetWebService(url, "getVerifyCode", ht);
 if (msg.Substring(0, 2)=="NG")
 {
      MessageForm mf = new MessageForm("总成,加密接口通信异常!", msg, true);
      mf.ShowDialog();
      return; 

}

//接收反馈信息

string EnBarCode = webServiceHelper.GetReturnInnerMsg(msg);
