完整的webservice接口调用过程

查看调用方法

调用地址：http://localhost:8080/WP_FOTON_FSOA/APP_FACTOR_SERVICES/Proxy_Services/TA_SAP/FACTOR_SYC_238_SendEarnestMoneyInfo_PS?wsdl

根据接口的wsdl文档可以看到调用的接口方法（FACTOR_SYC_238_SendEarnestMoneyInfoService）以及反馈参数（getFACTOR_SYC_238_SendEarnestMoneyInfoResponse）里的SIGN，MESSAGE。

 查看调用格式

可以用解析webservice的框架解析也可以使用外部工具，如SoapUI解析，如下（SoapUI示例）；通过SoapUI即可查看调用接口的SOAP格式

 调用接口

调用接口可通过wsimport编译，将接口的wsdl编译成本地实体类，然后调用实体类的方法即可，下面演示使用Post直接请求的方式。

一、post请求方法

package com.lwl.util;

import sun.misc.BASE64Encoder;

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.nio.charset.StandardCharsets;

/**
 * post请求
 *
 * @author liuwenlong
 * @create 2021-12-04 12:25:00
 */
@SuppressWarnings("all")
public class SendPost {

    /**
     * Post请求一个地址
     *
     * @param URL         请求地址
     * @param requestBody 请求的body
     * @param Authorization 账号密码
     * @return 返回调用结果
     */
    public String doPost(String URL, String requestBody,String Authorization) {
        OutputStreamWriter out = null;
        BufferedReader in = null;
        StringBuilder result = new StringBuilder();
        HttpURLConnection conn = null;

        try {
            java.net.URL url = new URL(URL);
            conn = (HttpURLConnection) url.openConnection();
            BASE64Encoder base = new BASE64Encoder();
            String encodedPassword = base.encode(Authorization.getBytes("UTF-8"));
            //System.out.println("加密后的密码：" + encodedPassword);
            //将加密的账号密码放到请求头里，这里注意Basic后面要加空格
            conn.setRequestProperty("Authorization", "Basic " + encodedPassword);
            conn.setRequestMethod("POST");
            //发送POST请求必须设置为true
            conn.setDoOutput(true);
            conn.setDoInput(true);
            //设置连接超时时间和读取超时时间
            conn.setConnectTimeout(3000);
            conn.setReadTimeout(3000);
            conn.setRequestProperty("Content-Type","text/xml;charset=UTF-8");
            //conn.setRequestProperty("Accept", "application/json");
            //获取输出流，写入请求的json或者xml报文
            out = new OutputStreamWriter(conn.getOutputStream(),"utf-8");
            //System.out.println(requestBody);

            out.write(requestBody); //获取请求的body,
            out.flush();
            out.close();
            //取得输入流，并使用Reader读取
            if (200 == conn.getResponseCode()) {
                in = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8));
                String line;
                while ((line = in.readLine()) != null) {
                    result.append(line);
                    //System.out.println(line);
                }
            } else {
                System.out.println("ResponseCode is an error code:" + conn.getResponseCode());
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (out != null) {
                    out.close();
                }
                if (in != null) {
                    in.close();
                }
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
        }
        return result.toString();
    }

}

二、组装报文，调用方法

package com.restful.client.config.FFS;

import com.lwl.util.SendPost;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;

/**
 * @author liuwenlong
 * @create 2021-12-04 12:25:31
 */
@SuppressWarnings("all")
public class SYC_238 {
    public static void main(String[] args) {
        //请求地址
        String test_URL_SYC_238 = "http://localhost:8080/WP_FOTON_FSOA/APP_FACTOR_SERVICES/Proxy_Services/TA_SAP/FACTOR_SYC_238_SendEarnestMoneyInfo_PS?wsdl";
    
        SendPost sendPost = new SendPost();
        String username = "admin"; //账号
        String password = "admin111"; //密码
        String Authorization = username + ":" + password;

        String sendMessage = "请求报文放这里";

        String requestBody = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:fac=\"http://www.***.com.cn/FACTOR_SYC_238_SendEarnestMoneyInfo\">\n" +
                "   <soapenv:Header/>\n" +
                "   <soapenv:Body>\n" +
                "      <fac:FACTOR_SYC_238_SendEarnestMoneyInfoService>\n" +
                "         <fac:DATA><![CDATA[" + sendMessage + "]]></fac:DATA>\n" +
                "      </fac:FACTOR_SYC_238_SendEarnestMoneyInfoService>\n" +
                "   </soapenv:Body>\n" +
                "</soapenv:Envelope>";
        System.out.println("requestBody\n" + requestBody);
        String responseBody = sendPost.doPost(test_URL_SYC_238, requestBody, Authorization);
        System.out.println("responseBody:\n" + responseBody);

    }
}

三、获取反馈，获取反馈可以直接根据wsdl里getFACTOR_SYC_238_SendEarnestMoneyInfoResponse方法，并取出WSDL文档里描述的SIGN，MESSAGE；

        Document doc = null;
        try {
            doc = DocumentHelper.parseText(responseBody.trim());
        } catch (
                DocumentException e) {
            e.printStackTrace();
        }
        Element root = doc.getRootElement();// 指向根节点
        String message = root.element("Body").element("getFACTOR_SYC_238_SendEarnestMoneyInfoResponse").elementTextTrim("MESSAGE").trim();
        String sign = root.element("Body").element("getFACTOR_SYC_238_SendEarnestMoneyInfoResponse").elementTextTrim("SIGN").trim();

        System.out.println("\n反馈报文:" + message);
        System.out.println("标识:" + sign);
        String result = "";
        if ("0".equals(sign)) {
            result = "调用成功！";
        } else {
            result = "调用失败！";
        }
        System.out.println(result);
