Question

Hiii 更新2： 感谢4的帮助。 我现在得到了饼干，但我被困在同一页面上。 我添加了cookie作为标题与请求，但我得到了相同的页面作为响应。 不知道我做错了。 请指导我。

org.apache.http.impl.client.AbstractHttpClient httpclient = new org.apache.http.impl.client.DefaultHttpClient(); 
    try { 
     // Create a local instance of cookie store 
     CookieStore cookieStore = new BasicCookieStore(); 

     // Create local HTTP context 
     HttpContext localContext = new BasicHttpContext(); 
     // Bind custom cookie store to the local context 
     System.out.println("Binding Cookie from Cookie Store="+this.cookies); 
     String c=this.cookies.replaceAll("Set-Cookie: ", ""); 
     String c1=c.replaceAll(";path=/", ""); 
     System.out.println("c="+c1); 
     String []ar=c1.split("="); 
     System.out.println("a[0]="+ar[0]); 
     System.out.println("a[1]="+ar[1]); 
     BasicClientCookie cookie = new BasicClientCookie(ar[0], ar[1]); 
     cookie.setDomain("indianvisa-bangladesh.nic.in"); 
     cookie.setPath("/"); 
     cookieStore.addCookie(cookie); 
     httpclient.setCookieStore(cookieStore); 


     localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); 

     HttpGet httpget = new HttpGet("http://indianvisa-bangladesh.nic.in/visa/Get_Appointment"); 

     System.out.println("executing request " + httpget.getURI()); 

     // Pass local context as a parameter 
     HttpResponse response = httpclient.execute(httpget, localContext); 
     HttpEntity entity = response.getEntity(); 

     System.out.println("----------------------------------------"); 
     System.out.println(response.getStatusLine()); 
     if (entity != null) { 
      System.out.println("Response content length: " + entity.getContentLength()); 
     } 
     List<Cookie> cookies = cookieStore.getCookies(); 
     for (int i = 0; i < cookies.size(); i++) { 
      System.out.println("Local cookie: " + cookies.get(i)); 
     } 
     BufferedReader rd = new BufferedReader(
       new InputStreamReader(response.getEntity().getContent())); 
     StringBuffer result = new StringBuffer(); 
     String line = ""; 
     while ((line = rd.readLine()) != null) { 
      result.append(line); 
     } 
     System.out.println("Page contect="+result); 

     // Consume response content 
     EntityUtils.consume(entity); 

     System.out.println("----------------------------------------"); 

    } finally { 
     // When HttpClient instance is no longer needed, 
     // shut down the connection manager to ensure 
     // immediate deallocation of all system resources 
     //httpclient.getConnectionManager().shutdown(); 
    }

尝试迭代httpclient.getCookieStore();
