WebService學習筆記(一)

一、基礎進階

  1. httpclient調用WebService
package com.demo;

import com.midea.gls.MobileCodeWS;
import com.midea.gls.MobileCodeWSSoap;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class WSHttpClient {



    public static void main(String[] args) {
        String mobileCode = "18680586568";

       // get(mobileCode);
//        post(mobileCode);

        soap(mobileCode);
    }

    public static void get(String mobileCode){
        HttpClient client = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet("http://ws.webxml.com.cn//WebServices/MobileCodeWS.asmx/getMobileCodeInfo?mobileCode="+mobileCode+"&userID=");
        try {
            HttpResponse response = client.execute(httpGet);
            System.out.println("executing request " + httpGet.getURI());
            // 獲取響應實體
            HttpEntity entity = response.getEntity();
            System.out.println("--------------------------------------");
            // 打印響應狀態
            System.out.println(response.getStatusLine());
            if (entity != null) {
                // 打印響應內容長度
                System.out.println("Response content length: " + entity.getContentLength());
                // 打印響應內容
                System.out.println("Response content: " + EntityUtils.toString(entity));
            }
            System.out.println("------------------------------------");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void post(String mobileCodeVal){
        HttpClient client = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost("http://ws.webxml.com.cn//WebServices/MobileCodeWS.asmx/getMobileCodeInfo");
        try {
            //設置參數
            List<NameValuePair> list = new ArrayList<NameValuePair>();
            list.add(new BasicNameValuePair("mobileCode",mobileCodeVal));
            list.add(new BasicNameValuePair("userID",""));
            UrlEncodedFormEntity requestEntiry = new UrlEncodedFormEntity(list);
            httpPost.setEntity(requestEntiry);
            HttpResponse response = client.execute(httpPost);
            System.out.println("executing request " + httpPost.getURI());
            // 獲取響應實體
            HttpEntity httpEntity = response.getEntity();
            System.out.println("--------------------------------------");
            // 打印響應狀態
            System.out.println(response.getStatusLine());
            if (httpEntity != null) {
                // 打印響應內容長度
                System.out.println("Response content length: " + httpEntity.getContentLength());
                // 打印響應內容
                System.out.println("Response content: " + EntityUtils.toString(httpEntity));
            }
            System.out.println("------------------------------------");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void soap(String mobileVal){
        MobileCodeWS mobileCodeWS = new MobileCodeWS();
        MobileCodeWSSoap mobileCodeWSSoap = mobileCodeWS.getMobileCodeWSSoap();
        String address = mobileCodeWSSoap.getMobileCodeInfo(mobileVal, null);
        System.out.println(address);
    }
}
  1. wsimport調用WSDL
wsimport -s . -p com.midea.gls http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx?WSDL

找到WSDL中關于service的調用

    public static void soap(String mobileVal){
        MobileCodeWS mobileCodeWS = new MobileCodeWS();
        MobileCodeWSSoap mobileCodeWSSoap = mobileCodeWS.getMobileCodeWSSoap();
        String address = mobileCodeWSSoap.getMobileCodeInfo(mobileVal, null);
        System.out.println(address);
    }

二 、 發布自己的WSDL

發布自己的WSDL時候,需要注意，地址欄后面要自己加?WSDL

package com.demo;

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

/**
 * \* Created with IntelliJ IDEA.
 * \* Author: huyi
 * \* Date: 2017/2/20 13:32
 * \* Description:
 * \
 */
@WebService
public class MyWS {

    public String sayHello(String name) {
        String reVal = name + ", 你好!";
        System.out.println(reVal);
        return reVal;
    }

    public static void main(String[] args) {
        String address = "http://10.74.96.29/ws";
        Endpoint.publish(address , new MyWS());
        System.out.println("發布的地址是:"+address);
    }
}

訪問http://10.74.96.29/ws?WSDL，可以見到

<soap:operation soapAction="" style="document"/>
<wsdl:input name="sayHello">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="sayHelloResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="MyWSService">
<wsdl:port binding="tns:MyWSServiceSoapBinding" name="MyWSPort">
<soap:address location="http://10.74.96.29/ws"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

三 、客戶端訪問

  1. 首先在CMD中調用wsimport工具生成本地WebService代碼
wsimport -s . -p com.ws http://10.74.96.29/ws?WSDL
  1. 導入代碼到本地項目后，直接調用即可
    public static void soap2(String mobileVal){
        MyWS mobileCodeWS = new MyWS();
        String name = "huyi";
        String reVal = mobileCodeWS.sayHello(name);
        System.out.println(reVal);
    }

注意：一個端口可以發布多個Webservice服務

四 、ajax訪問WebService

ajax不能直接訪問WebService，因為存在跨域的問題，需要變通一下，通過ajax調用工程下的客戶端訪問WebService，客戶端可以是一個servlet，或者spring下的controller

ws.jsp
