前言

兄弟们来了来了，最近有人在问如何模拟新浪微博登陆抓取数据，我听后默默地抽了一口老烟，暗暗的对自己说，老汉是时候该你出场了，所以今天有时间就整理整理，浅谈一二.

首先:

要想登陆新浪微博需要预登陆，即是将账号base64加密，密码rsa加密以及请求http://login.sina.com.cn/sso/prelogin.php链接获取一些登陆需要参数，返回的接送字符串如:

?
1
{ "retcode" : 0 , "servertime" : 1487292003 , "pcid" : "gz-9e1f24c9acdefb111e1c8078558c7d9c0bf2" , "nonce" : "VHRDG1" , "pubkey" : "EB2A38568661887FA180BDDB5CABD5F21C7BFD59C090CB2D245A87AC253062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443" , "rsakv" : "1330428213" , "is_openlock" : 0 , "lm" : 1 , "smsurl" : "https:\/\/login.sina.com.cn\/sso\/msglogin?entry=weibo&mobile=18360903574&s=ea7a2e91c5f1d6da7f42aa87fe6963d0" , "showpin" : 0 , "exectime" : 222 }

，接下来是预登陆处理代码:

/**

  public boolean preLogin(){
  boolean flag = false ;
  try {
  su = new String(Base64.encodeBase64(URLEncoder.encode(username, "UTF-8" ).getBytes()));
  String url = "http://login.sina.com.cn/sso/prelogin.php?entry=weibo&rsakt=mod&checkpin=1&" +
   "client=ssologin.js(v1.4.5)&_=" + getTimestamp();
  url += "&su=" + su;
  String content;
  content = HttpUtils.getRequest(client, url);
  System.out.println( "content------------" + content);
  JSONObject json = JSONObject.fromObject(content);
  System.out.println(json);
  servertime = json.getLong( "servertime" );
  nonce = json.getString( "nonce" );
  rsakv = json.getString( "rsakv" );
  pubkey = json.getString( "pubkey" );
  flag = encodePwd();
  } catch (UnsupportedEncodingException e) {
  System.out.println( "抛出UnsupportedEncoding异常" );
  } catch (ClientProtocolException e) {
  System.out.println( "抛出ClientProtocol异常" );
  } catch (IOException e) {
  System.out.println( "抛出IO异常" );
  }
  return flag;
  }

其次:

获取登陆需要的参数后使用post请求http://login.sina.com.cn/sso/login.php，将上述预登陆后处理数据作为参数代入请求，得到结果如下:

try{sinaSSOController.setCrossDomainUrlList({"retcode":0,"arrURL":["http:\/\/passport.97973.com\/sso\/crossdomain?action=login&savestate=1518828005","http:\/\/passport.weibo.cn\/sso\/crossdomain?action=login&savestate=1"]});}
  catch(e){
  var msg = e.message;
  var img = new Image();
  var type = 1;
  img.src = 'http://login.sina.com.cn/sso/debuglog?msg=' + msg +'&type=' + type;
  }try{sinaSSOController.crossDomainAction('login',function(){location.replace('http://passport.weibo.com/wbsso/login?ssosavestate=1518828005&url=http%3A%2F%2Fweibo.com%2Fajaxlogin.php%3Fframelogin%3D1%26callback%3Dparent.sinaSSOController.feedBackUrlCallBack&ticket=ST-NTUwODg3MjkxMQ==-1487292005-gz-FF56C545999F864FC6C7AB86FCA9FA4A-1&retcode=0');});}
  catch(e){
  var msg = e.message;
  var img = new Image();
  var type = 2;
  img.src = 'http://login.sina.com.cn/sso/debuglog?msg=' + msg +'&type=' + type;
  }
</ script >
</ body >
</ html >

然后用正则截取其中我们想要的部分：location.replace（''）中间部分，正则表达式为:

String regex = "location.replace\\('([\\s\\S]*?)'\\);",

将正则得到的结果进行处理，如果成功则使用get请求得到的链接，登陆部分的代码如下:

  InputStream con= HttpUtils.getRequests(client, "http://weibo.com/u/" +uniqueid+userdomain);//请求个人主页获取输入流
  String cont = readStreamByEncoding(con, "UTF-8" ); //将返回的输入流转换为字符串
  String sb =HttpUtils.getText(cont); //通过jsoup获取text内容部分
  //readStreamOutFileByEncoding(sb);也可已将获取的内容写入文件中
  } else {
  System.out.println( "登录失败！" );
  }
  }

得到的结果为:
