java如何实现post请求webservice服务端

目录post请求webservice服务端1.例如我此时有一个wsdl文件2.点击row查看具体的发送参数3.代码实现3.1参数说明用post请求调用webservice

post请求webservice服务端

当生成webService的客户端不好实现时，通过java的post请求不失为一种好办法。

1.例如我此时有一个wsdl文件

http://xxx.xxx.xxx.xxx:8081/APIService.svc?wsdl

2.通过SoapUI 我们可以将swdl文件转换。从而模拟发送请求。以及参数

(不懂soapui请自行百度)

2.点击row查看具体的发送参数

具体参数对应规则（以下对应代码上应该发送的参数是什么）

3.代码实现

public static void main(String[] args) {

try{

String url="http://xxx.xxx.xxx.xxx:8081/APIService.svc";

String params="\n" +

" \n" +

"";

String host="xxx.xxx.xxx.xxx:8081";

String SOAPAction="http://aaa/aaa/aaa";

//接受返回报文

String result = new String();

URL u = new URL(url);

HttpURLConnection conn = (HttpURLConnection) u.openConnection();

conn.setDoInput(true);

//允许对外输出数据

conn.setDoOutput(true);http://

conn.setUseCaches(false);

conn.setDefaultUseCaches(false);

conn.setRequestProperty("Host",host);

conn.setRequestProperty("Content-Type","text/xml;charset=UTF-8");

//soap

conn.setRequestProperty("SOAPAction",SOAPAction);

conn.setRequestProperty("Content-Length",String.valueOf(params.length()));

conn.setRequestMethod("POST");

//定义输出流

OutputStream output = conn.getOutputStream();

if(StringUtils.isNotBlank(params)){

byte[] b = params.getBytes("UTF-8");

//发送soap请求报文

output.write(b,0,b.length);

output.flush();

output.close();

//定义输入流，获取soap报文

InputStream input = conn.getInputStream();

//设置编码格式

result = IOUtils.toString(input,"UTF-8");

input.close();

}

System.out.println("请求返回报文：" + result);

}catch (Exception e){

System.out.println(e.getMessage());

}

3.1参数说明

url：这个地址即wsdl文件地址去掉后缀 “?wsdl”。如此例就是：wsdl：

http://xxx.xxx.xxx.xxx:8081/APIService.svc?wsdl

url：

http://xxx.xxx.xxx.xxx:8081/APIService.svc

params：这个即是请求的参数host：这个是对方的主机地址和端口号。如此例为： xxx.xxx.xxx.xxx:8081SOAPAction：具体service路径

用post请求调用webservice

先说下遇到的坑，最先用post请求的时候一直返回500的错误码

最终通过打印错误信息分析，请求头必须添加SOAPAction

//请求头必须设置SOAPAction

connection.setRequestProperty("SOAPAction","application/soap+xml; charset=utf-8");

xml转json需要用到hutool-all-4.0.12.jar，解析json比xml要简单得多。

如果不需要用xml转json，除需要jdk自带的包不再需要引入其他的包。

package com.baidu.util;

import cn.hutool.json.XML;

import net.sf.json.JSONObject;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.net.HttpURLConnection;

import java.net.URL;

/**

* 发送http post调用webservice

* @param strUrl

* @param requestSoapXml

* @return

* @throws IOException

public static String soapPost(String strUrl, String requestSoapXml) throws IOException {

//第一步：创建服务地址，不是WSDL地址

URL url = new URL(strUrl);

//第二步：打开一个通向服务地址的连接

HttpURLConnection connection = (HttpURLConnection) url.openConnection();

//第三步：设置参数

//3.1发送方式设置：POST必须大写

connection.setRequestMethod("POST");

//3.2设置数据格式：content-type

connection.setRequestProperty("content-type", "text/xml;charset=utf-8");

//3.3设置输入输出，因为默认新创建的connection没有读写权限，

connection.setDoInput(true);

connection.setDoOutput(true);

//请求头必须设置SOAPAction

connection.setRequestProperty("SOAPAction","application/soap+xml; charset=utf-8");

//第四步：组织SOAP数据，发送请求

OutputStream os = connection.getOutputStream();

//os.write(requestSoapXml.getBytes());这个方法遇到一个大坑记录下

//当时在开发工具中通过这个方法调用接口一切都OK，但是放到客户服务器上发送post

//请求就返回500错误，错误信息太少，走了很多弯路，百度无果后，

//后面灵机一动，会不会是传输的数据编码不对，

//导致接口服务端解析请求数据报错从而返回500错误码，

//其实我是不知道服务端到底用的什么编码，

//经过尝试 os.write(requestSoapXml.getBytes("utf-8"));

//结果成功了，根据实际情况这个编码会改动

os.write(requestSoapXml.getBytes());

//第五步：接收服务端响应，打印

int responseCode = connection.getResponseCode();

//==============打印错误信息

// try{

// InputStream iss = connection.getErrorStream(); //通过getErrorStream了解错误的详情

// InputStreamReader isrs = new InputStreamReader(iss,"utf-8");

// BufferedReader ins = new BufferedReader(isrs);

// String inputLine;

// BufferedWriter bws = new BufferedWriter(new OutputStreamWriter(

// new FileOutputStream("result.xml")));// 将结果存放的位置

// while ((inputLine = ins.readLine()) != null)

// {

// System.out.println(inputLine);

// bws.write(inputLine);

// bws.newLine();

// }

// bws.close();

// }catch (Exception e){

// }

//==============

StringBuilder sb = new StringBuilder();

if (200 == responseCode) {//表示服务端响应成功

InputStream is = connection.getInputStream();

InputStreamReader isr = new InputStreamReader(is);

BufferedReader br = new BufferedReader(isr);

String temp = null;

while (null != (temp = br.readLine())) {

sb.append(temp);

}

is.close();

isr.close();

br.close();

}else{

throw new RuntimeException("调用webservice失败：服务器端返回HTTP code " + responseCode + "信息：" );

}

os.close();

return sb.toString();
