}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);
