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
|
1 |
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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
public static void main(String[] args) { try { String url= "http://xxx.xxx.xxx.xxx:8081/APIService.svc" ; String params= "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\" xmlns:hn=\"http://schemas.datacontract.org/2004/07/hn.DataAccess.bll\">\n" + " </tem:input>\n" + " </soapenv:Body>\n" + "</soapenv:Envelope>" ; 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 ); 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 ：
|
1 |
http: //xxx.xxx.xxx.xxx:8081/APIService.svc?wsdl |
url ：
|
1 |
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:8081 SOAPAction ：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
|
1 2 |
//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。
