java如何實現(xiàn)post請求webservice服務(wù)端

這篇文章主要介紹了java如何實現(xiàn)post請求webservice服務(wù)端，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教
post請求webservice服務(wù)端
當生成webService的客戶端不好實現(xiàn)時，通過java的post請求不失為一種好辦法。
1.例如我此時有一個wsdl文件
http://xxx.xxx.xxx.xxx:8081/APIService.svc?wsdl
2.通過SoapUI 我們可以將swdl文件轉(zhuǎn)換。從而模擬發(fā)送請求。以及參數(shù)
(不懂soapui請自行百度)
2.點擊row查看具體的發(fā)送參數(shù)
具體參數(shù)對應(yīng)規(guī)則（以下對應(yīng)代碼上應(yīng)該發(fā)送的參數(shù)是什么）
3.代碼實現(xiàn)
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";
//接受返回報文
String result = new String();
URL u = new URL(url);
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.setDoInput(true);
//允許對外輸出數(shù)據(jù)
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");
//定義輸出流
OutputStream output = conn.getOutputStream();
if(StringUtils.isNotBlank(params)){
byte[] b = params.getBytes("UTF-8");
//發(fā)送soap請求報文
output.write(b,0,b.length);
output.flush();
output.close();
//定義輸入流，獲取soap報文
InputStream input = conn.getInputStream();
//設(shè)置編碼格式
result = IOUtils.toString(input,"UTF-8");
input.close();
}
System.out.println("請求返回報文：" + result);
}catch (Exception e){
System.out.println(e.getMessage());
}
}3.1參數(shù)說明
url：這個地址即wsdl文件地址去掉后綴 “?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：這個即是請求的參數(shù)host：這個是對方的主機地址和端口號。 如此例為： xxx.xxx.xxx.xxx:8081SOAPAction：具體service路徑
用post請求調(diào)用webservice
先說下遇到的坑，最先用post請求的時候一直返回500的錯誤碼
最終通過打印錯誤信息分析，請求頭必須添加SOAPAction
//請求頭必須設(shè)置SOAPAction
connection.setRequestProperty("SOAPAction","application/soap+xml; charset=utf-8");?xml轉(zhuǎn)json需要用到hutool-all-4.0.12.jar，解析json比xml要簡單得多。
如果不需要用xml轉(zhuǎn)json，除需要jdk自帶的包不再需要引入其他的包。
package com.baidu.util;
import cn.hutool.json.XML;

public class SoapUtil {
/**

* @param strUrl
* @param requestSoapXml

public static String soapPost(String strUrl, String requestSoapXml) throws IOException {
//第一步：創(chuàng)建服務(wù)地址，不是WSDL地址
URL url = new URL(strUrl);
//第二步：打開一個通向服務(wù)地址的連接
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
//第三步：設(shè)置參數(shù)
//3.1發(fā)送方式設(shè)置：POST必須大寫
connection.setRequestMethod("POST");
//3.2設(shè)置數(shù)據(jù)格式：content-type
connection.setRequestProperty("content-type", "text/xml;charset=utf-8");
//3.3設(shè)置輸入輸出，因為默認新創(chuàng)建的connection沒有讀寫權(quán)限，
connection.setDoInput(true);
connection.setDoOutput(true);
//請求頭必須設(shè)置SOAPAction
connection.setRequestProperty("SOAPAction","application/soap+xml; charset=utf-8");
//第四步：組織SOAP數(shù)據(jù)，發(fā)送請求
OutputStream os = connection.getOutputStream();
//os.write(requestSoapXml.getBytes());這個方法遇到一個大坑記錄下
//當時在開發(fā)工具中通過這個方法調(diào)用接口一切都OK，但是放到客戶服務(wù)器上發(fā)送post
//請求就返回500錯誤，錯誤信息太少，走了很多彎路，百度無果后，
//后面靈機一動，會不會是傳輸?shù)臄?shù)據(jù)編碼不對，
//導致接口服務(wù)端解析請求數(shù)據(jù)報錯從而返回500錯誤碼，
//其實我是不知道服務(wù)端到底用的什么編碼，
//經(jīng)過嘗試 os.write(requestSoapXml.getBytes("utf-8"));
//結(jié)果成功了，根據(jù)實際情況這個編碼會改動
os.write(requestSoapXml.getBytes());
//第五步：接收服務(wù)端響應(yīng)，打印
int responseCode = connection.getResponseCode();
//==============打印錯誤信息
// try{
// InputStream iss = connection.getErrorStream(); //通過getErrorStream了解錯誤的詳情
// InputStreamReader isrs = new InputStreamReader(iss,"utf-8");
// BufferedReader ins = new BufferedReader(isrs);
// String inputLine;
// BufferedWriter bws = new BufferedWriter(new OutputStreamWriter(
// new FileOutputStream("result.xml")));// 將結(jié)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) {//表示服務(wù)端響應(yīng)成功
