java 接口中模擬瀏覽器 請求webservice 接受返回數據


1、使用HttpClient 

2、所需的依賴jar包: commons-codec-1.9.jar

          commons-httpclient-3.1.jar

 

3、具體代碼

   

 1 try {
 2   HttpClient client = new HttpClient(new HttpClientParams(),new  SimpleHttpConnectionManager(true));
 3   HttpMethod method = null;
 4   String uri = "{接口的uRL直接帶參數}}";
 5   method = new GetMethod(uri);
 6 
 7   //瀏覽器的requestHeader 模擬瀏覽器
 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     //執行getMethod 
13     int statusCode = client.executeMethod(method);
14     if (statusCode != HttpStatus.SC_OK) { 
15       System.err.println("Method failed: "+ method.getStatusLine()); 
16     } 
17     //讀取內容 
18       String dataXml = method.getResponseBodyAsString();
19     //處理內容 
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       //發生致命的異常,可能是協議不對或者返回的內容有問題 
29       System.out.println("Please check your provided http address!"); 
30      e.printStackTrace(); 
31   } catch (IOException e) { 
32     //發生網絡異常 
33       e.printStackTrace(); 
34   } finally { 
35     //釋放連接 
36       method.releaseConnection(); 
37   } 
38 }catch(Exception e)
39 { 
40   e.printStackTrace();
41 }
