java 使用HttpC'lient 解析webService

如果你的webService 地址直接类似于（天气预报：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx）这样的：

 

 

点击你要解析的方法，进入如下：

 

 

  然后使用HttpClient 解析webService :

 

package com.example.util;

import org.apache.http.HttpEntity;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.Charset;
import java.util.List;

public class WebServiceUtil {

    private static Logger log = LoggerFactory.getLogger("webServiceUtil-log");
    private static int socketTimeOut = 30000;//请求超时时间
    private static int connectTimeOut = 30000;//传输超时时间

    public static void main(String[] args){
        String storeInfoUrl = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx";
        String contentType = "text/xml; charset=utf-8";//soap1.1 的conetentType
        String soapAction = "http://WebXml.com.cn/getSupportCity";
//        String soapAction ="";
//        String contentType = "application/soap+xml; charset=utf-8"; //soap1.2 的conetentType
        String ProvinceName = "上海";
        String soapXml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
                "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" +

                "  </soap:Body>\n" +
                "</soap:Envelope>";
        InputStream input = WebServiceUtil.soap(storeInfoUrl, soapXml, soapAction, contentType);
        //下面是解析 返回的 XML
        SAXReader saxReader = new SAXReader();
        Document document = null;
        try {
            document = saxReader.read(input);
            Element root = document.getRootElement();
          Dom4jUtils.getNodes(root);
          Element body = root.element("Body");
          Element getSupportCityResponse = body.element("getSupportCityResponse");
          Element getSupportCityResult = getSupportCityResponse.element("getSupportCityResult");
            List<Element> strings =  getSupportCityResult.elements();
            for(Element e : strings){
               System.out.println(e.getTextTrim());
            }

        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }



    public static InputStream soap(String url,String soapXml,String soapAction,String ContentType)  {


        InputStream soapResponseData = null;
        // 创建HttpClientBuilder
        HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
        // HttpClient
        CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
        HttpPost httpPost = new HttpPost(url);
         //设置请求超时时间 和 传输超时时间
        RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(socketTimeOut)
                .setConnectTimeout(connectTimeOut).build();
        httpPost.setConfig(requestConfig);

        httpPost.setHeader("Content-Type",ContentType);
        httpPost.setHeader("SOAPAction",soapAction);
        StringEntity data = new StringEntity(soapXml, Charset.forName("UTF-8"));
        httpPost.setEntity(data);
        CloseableHttpResponse response = null;
        try {
            response = closeableHttpClient.execute(httpPost);
            HttpEntity httpEntity = response.getEntity();
            if (httpEntity !=null){
                //打印响应内容
                byte[]  bytes = EntityUtils.toByteArray(httpEntity);
                soapResponseData =new ByteArrayInputStream(bytes);
                log.info("---请求webService之后的返回值是----"+new String(bytes));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }finally {
            try {
                closeableHttpClient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }



        return soapResponseData;






    }
}

 

 

 如果 接口地址是 http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl 带 ?wsdl

需要使用 soapUI 等工具：

然后后面的的解析和上面的一样。
