java 接口中模拟浏览器 请求webservice 接受返回数据

1、使用HttpClient 

2、所需的依赖jar包: commons-codec-1.9.jar

          commons-httpclient-3.1.jar

3、具体代码

   

 1 try {
 2   HttpClient client = new HttpClient(new HttpClientParams(),new  SimpleHttpConnectionManager(true));
 3   HttpMethod method = null;
 4   String uri = "{接口的uRL直接带参数}}";
 5   method = new GetMethod(uri);
 6 
 7   //浏览器的requestHeader 模拟浏览器
 8    method.setRequestHeader("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36");
 9   method.setRequestHeader("Accept","image/webp,image/*,*/*;q=0.8");
10   method.setRequestHeader("Cookie","ORA_BIPS_LBINFO=157b18e65d9; ORA_BIPS_NQID=jifecsdccfgkctabqnhk687a48hdaqsthos17jofllohscns");
11   try { 
12     //执行getMethod 
13     int statusCode = client.executeMethod(method);
14     if (statusCode != HttpStatus.SC_OK) { 
15       System.err.println("Method failed: "+ method.getStatusLine()); 
16     } 
17     //读取内容 
18       String dataXml = method.getResponseBodyAsString();
19     //处理内容 
20       System.out.println(new String(dataXml)); 
21     JSONObject json = Xml2JsonUtil.xml2JSON(dataXml);
22     response.setContentType("text/plain; charset=UTF-8");
23     response.getWriter().write(json.toString());
24     response.getWriter().flush();
25     response.getWriter().close();
26   } catch (HttpException e) 
27   { 
28       //发生致命的异常,可能是协议不对或者返回的内容有问题 
29       System.out.println("Please check your provided http address!"); 
30      e.printStackTrace(); 
31   } catch (IOException e) { 
32     //发生网络异常 
33       e.printStackTrace(); 
34   } finally { 
35     //释放连接 
36       method.releaseConnection(); 
37   } 
38 }catch(Exception e)
39 { 
40   e.printStackTrace();
41 }
