最近弄了一個工具,希望能獲取自己百度網盤里面的數據但又不想公開數據,于是想到了模擬登陸百度,用常規的模擬登陸測試了下發現不行,抓取登陸時的數據才發現,其實百度登陸過程中跳轉了幾次頁面,如果僅僅對http://passport.baidu.com/v2/api/?login一個頁面獲取cookie是不完整的那樣就只有BAIDUID的值,而僅僅這個cookie值是沒有多少作用的.

通過對抓包數據的分析,實際登陸過程中是先請求了一次http://passport.baidu.com/v2/api/?getapi&class=login&tpl=mn&tangram=true這個頁面,服務器同時給瀏覽器設置兩個cookie,一個BAIDUID的cookie值,這個應該是與seesion id相關的;另一個是

Set-Cookie:

HOSUPPORT=1; expires=Thu,19-Aug-2021 15:41:37 GMT; path=/; domain=passport.baidu.com; httponly

推測這個應該是百度檢測瀏覽器是否支持cookie；

再次請求該頁面,獲取網頁數據會得到一個token值用于登陸;

然后登陸成功會得到BDUSS等相關的cookie值,以上才是登陸成功,記錄下上面的cookie即可！

下面是簡單的請求及登陸函數集合,作為基礎類吧,可能簡單了點,以后再完善吧！

代碼如下:

<?php

class baidu{

private $cookie = '';

private $username = '';

private $password = '';

const COOKIE_DIR = 'temp';   //cookie存放目錄

const COOKIE_VALIDATE = 604800; //cookie有效期,默認為7天

const SECRET_KEY = 'hAFS6as8askNBVSuiealkkw'; //密鑰用于加密cookie文件名，防止保存的cookie路徑被猜測

private function http_request($url, $post_data, $referef,$header = true){

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, $url);

  if ($post_data != ""){

   curl_setopt($ch, CURLOPT_POST, 1);

   curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

  }

  if ($referef != ""){

   curl_setopt($ch, CURLOPT_REFERER, $referef);

  }

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

  curl_setopt($ch, CURLOPT_HEADER, $header);

  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31");

  if ($this->cookie != ""){

   curl_setopt($ch, CURLOPT_COOKIE, $this->cookie);

  }

  $data = curl_exec($ch);

  curl_close($ch);

  if ($header){

   preg_match_all('/Set-Cookie:((.+)=(.+))$/m ', $data, $cookies);

   if(is_array($cookies) && count($cookies) > 1 && count($cookies[1]) > 0){

    foreach($cookies[1] as $i => $k){

     $cookieinfos = explode(";", $k);

     if(is_array($cookieinfos) && count($cookieinfos) > 1){

      $this->cookie .= $cookieinfos[0];

      $this->cookie .= "; ";

     }

    }

   }

  }

  return $data;

}

private function login(){

  //生成一個cookie

  $ret = $this->http_request("https://passport.baidu.com/v2/api/?getapi&class=login&tpl=mn&tangram=true", "", "");

  //獲取token并保存cookie

  $ret = $this->http_request("https://passport.baidu.com/v2/api/?getapi&class=login&tpl=mn&tangram=true", "", "");

  preg_match_all('/login_token='(.+)'/', $ret, $tokens);

  $login_token = $tokens[1][0];

  //登陸并保存cookie

  $post_data = array();

  $post_data['username'] = $this->username;

  $post_data['password'] = $this->password;

  $post_data['token'] = $login_token;

  $post_data['charset'] = "UTF-8";

  $post_data['callback'] = "parent.bd12Pass.api.login._postCallback";

  $post_data['index'] = "0";

  $post_data['isPhone'] = "false";

  $post_data['mem_pass'] = "on";

  $post_data['loginType'] = "1";

  $post_data['safeflg'] = "0";

  //記錄下所有cookie

  $this->writeCookie();

}

private function writeCookie(){

  if(!file_exists(self::COOKIE_DIR)){

   @mkdir(self::COOKIE_DIR) && touch(self::COOKIE_DIR.'/index.html');

  }

  $filename = self::COOKIE_DIR.'/'.md5($this->username.self::SECRET_KEY);

  file_put_contents($filename, $this->cookie);

}

public function baidu($username,$password){

  $this->username = $username;

  $this->password = $password;

  $filename = self::COOKIE_DIR.'/'.md5($this->username.self::SECRET_KEY);

  if ((@filemtime($filename)+ self::COOKIE_VALIDATE > time()) && ($cookie = file_get_contents($filename))!= ''){

  //如果cookie在有效期內且不為空

   $this->cookie = $cookie;

  }else {

   $this->login();

  }

}

/** www.49028c.com

  * 請求頁面

  * @param string $url  ：頁面地址

  * @param string $referef ：引用頁面

  * @param string $post_data ：post數據,如果填寫則為post方式否則為get方式

  * 返回頁面數據

  */

public function request($url,$referef = '',$post_data = ''){

  return $this->http_request($url,$referef,$post_data,false);

}

}

這個只是基本的類,只涉及登陸及請求與提交數據,可在此基礎上使用,例如請求百度云網盤,代碼如下:

$baidu = new baidu('用戶名','密碼');

$data = $baidu->request('http://pan.baidu.com/api/list?channel=chunlei&clienttype=0&web=1&num=100&page=1&dir=%2F','http://pan.baidu.com');

echo $data;
