用HTTP GET调用web service

下面的网址提供了国内飞机航班时刻表 WEB 服务
http://webservice.webxml.com.cn/webservices/DomesticAirline.asmx

wsdl如下：
http://webservice.webxml.com.cn/webservices/DomesticAirline.asmx?wsdl

调用web service可以采用很多方式 比如axis2、xfire、cxf都可以根据wsdl反向生成客户端代码 简化开发

下面我采用的是http get的方式调用其web service，采用的是HttpClient4

import java.net.URLEncoder;

import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.HttpProtocolParams;

public class DomesticAirlineTest {
        public static void main(String[] args) throws Exception{
        String url = "/webservices/DomesticAirline.asmx/getDomesticAirlinesTime";
        String host = "www.webxml.com.cn";
        String param = "startCity="+URLEncoder.encode("北京", "utf-8")+"&lastCity="+URLEncoder.encode("上海", "utf-8")+"&theDate=&userID=";

        HttpClient httpclient = new DefaultHttpClient();
        httpclient.getParams().setParameter(HttpProtocolParams.HTTP_CONTENT_CHARSET,"UTF-8");

        HttpGet httpget = new HttpGet("http://"+host+url+"?"+param);

        ResponseHandler<String> responseHandler = new BasicResponseHandler();
        String responseBody = httpclient.execute(httpget, responseHandler);
        System.out.println(responseBody);
        httpclient.getConnectionManager().shutdown();
        }
}
