httpclient登录百度https登录地址

1、先get请求https://passport.baidu.com/v2/?login获取cookie

2、再通过get请求https://passport.baidu.com/v2/?login获取token

3、设置参数post请求https://passport.baidu.com/v2/api/?login登录地址，登录。

4、最后将请求百度首页就能查看到已登录。

（每次都得把cookie往后传递）

//获取cookie  请求get
        Result r1 = SendRequest.sendGet("https://passport.baidu.com/v2/?login", null, null, "GBK");
        //设置参数
        Map<String, String> params = new HashMap<String, String>();
        params.put("class", "login");
        params.put("tpl", "mn");
        params.put("tangram", "true");
        //获取头部信息
        Map<String, Header> headers = r1.getHeaders();
        //设置头部参数
        Map<String, String> headerMap = new HashMap<String, String>();
        for(String str : headers.keySet()){
        headerMap.put(str, headers.get(str).toString().substring(str.length()+2));
        }
        //设置cookie
        headerMap.put("Cookie", r1.getCookie());
        //请求获取token
        Result r = SendRequest.sendGet("https://passport.baidu.com/v2/api/?getapi&class=login&tpl=mn&tangram=true", headerMap, params, "GBK");
        //设置登录参数
        Map<String, String> params2 = new HashMap<String, String>();
        params2.put("class", "login");
        params2.put("tpl", "mn");
        params2.put("tangram", "true");
        params2.put("username", "账号");
        params2.put("password", "密码");
       
        params2.put("token", r.getToken());
        params2.put("isPhone", "false");
        params2.put("loginType", "1");
        params2.put("verifycode", "");
       
        params2.put("callback", "parent.bdPass.api.login._postCallback");
         
        //设置cookie   只需设置cookie  设置其他header参数会导致报错
        Map<String, String> headerMap2 = new HashMap<String, String>();
        headerMap2.put("Cookie", r.getCookie());
        //post登录请求
        Result result = SendRequest.sendPost("https://passport.baidu.com/v2/api/?login", headerMap2, params2, "UTF-8");
        //判断是否登录成功
        Map<String, String> headerMap3 = new HashMap<String, String>();
        //一定要设置cookie  否则会未登录
        headerMap3.put("Cookie", result.getCookie());
        //请求百度首页
        SendRequest.sendGet("http://www.baidu.com", headerMap3, null, "UTF-8");
