Question

@天体图 你好，帮我看看代码好吗：

String username = req.getParameter("username");
String pwd = req.getParameter("pwd");
try {
HttpClient httpclient = new DefaultHttpClient();
 
// 创建SSLContext对象，并使用我们指定的信任管理器初始化
TrustManager[] tm = { new MyX509TrustManager() };
SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
sslContext.init(null, tm, new java.security.SecureRandom());
// 创建SSLSocketFactory对象 
SSLSocketFactory ssf = new SSLSocketFactory(sslContext);  
 
   httpclient.getConnectionManager().getSchemeRegistry().register(new Scheme("https", 443, ssf));
 
   HttpPost post = new HttpPost("https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN");
    
   //Header cookie = new BasicHeader("Cookie", "ac=1,016,001; pt2gguin=o0503530115; RK=wD5qAuCPls; ptcz=2803611a23e59b710519c46b792d8df22cab01e413ca7b38e70465b1d6bc1df0; uin_cookie=1308300842; euin_cookie=70E0A746F5C21CF73A8B45D76B3098B3D71ECF8CF7C1D178; pgv_pvid=7669182920; cert=yAk4mLW8EJ02hefUt3BrpDoZSVPxpYmY");

   nvps.add(new BasicNameValuePair("f", "json"));
   nvps.add(new BasicNameValuePair("imgcode", ""));
   
   post.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));
 
   // 发送请求
   HttpResponse response = httpclient.execute(post);
   // 输出返回值
   java.io.InputStream is = response.getEntity().getContent();
   BufferedReader br = new BufferedReader(new InputStreamReader(is)); 
   String line = printAll(br);
   
   //printAll(br);
   br.close();
   String token = line.split("token=")[1].split(""")[0]; 
   HttpGet get = new HttpGet("https://mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token="+token);
   
   response = httpclient.execute(get);
   // 输出返回值
   is = response.getEntity().getContent();
   br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
   //printAll(br); 
   //br.close();
   res.getWriter().write(line);
} catch (Exception e) {
// TODO: handle exception

}
return null;

Answer 1

先提高下问问题的技巧，谢谢

Answer 2

你还是使用  htmlunit 好些 ，可以模拟  浏览器触发js，比较方便

Answer 3

我绝对不是大神，可能是我的博文标题让你产生了误解，我说的模拟登录是指“不用浏览器、用代码”实现登录并获取消息（因为不登录获取不了公众平台上的消息啊！），所以叫模拟登录。而你的是在你网站上点一个按钮，你后台访问了一下网址，然后想要前台的也跳转到这个网址，我说的那些是没法实现的，不好意思。你可以在站内问问真正的大神们
