HomeBackend DevelopmentPHP TutorialPHP采用curl模仿用户登陆新浪微博发微博的方法_php技巧

本文实例讲述了PHP采用curl模仿用户登陆新浪微博发微博的方法。分享给大家供大家参考。具体实现方法如下:

现在用php做模仿用户登录我们都会使用到PHP curl函数了,因为只有它才可以实现像用户一样的去访问别人网站了,下面就给大家介绍一下curl登陆新浪微博发微博应用例子。

前天接到一个需求需要模拟登陆微博然后进行发微博,以前干过很多的模拟登录阿里妈妈,微信,还有些其他的内部系统,至今没有出现不能登录的,哈哈,所以也就没有当一回事情,可是当分析新浪的登陆过程的时候才感觉到压力
遇到sha1(sha1(sha1(pwd)).once.servertime) ,肯定都用不了,主要使这个加密算法搞不定所以密码都搞不定别谈登录的,接着就在网上各种找代码,一个小时毫无所获。
是不是我用微博的帐号密码也能登录到新浪邮箱或者其他新浪产品去,感觉希望很大,果然微博的帐号可以直接登录所有的新浪产品,再次访问微博我已经在登录状态了,证明这个有神马用呢?

其实很有用的,一个大公司在一个项目投入的技术和这个项目盈利和前景有很大关系,微博他可以花很大的心思去做,但是其他就不一定,万一找到那个地方的密码没有加密那岂不是很好说了。(PS:对网络安全比较感兴趣,这个方式对黑客来说叫做旁注,旁注就是,当黑客在攻击一个网站的时候,这个网站安全做的非常好,没有什么已知漏洞,攻破难度较大,所以黑客会找找该网站下服务器下其他网站,然后找一个比较容易攻破的,通过这个网站挂马,shell,提权,然后目标网站也就沦陷,以为在同一个服务器,所以….目标就是拿到目标站,无论哪种方法只要拿下就行,很淫荡的想法有没有)

https://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.15)&_=1403138799543简单抓抓包发现密码并没有加密,我们不是能模拟登录了吗? 嗯,其实这里高兴的有点早了
先登录新浪的吧,代码分分钟就搞定了。返回的是一个json数组

复制代码 代码如下:
$password = $p;
$username = base64_encode($u);
$loginUrl = 'https://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.15)&_=1403138799543';
$loginData['entry'] = 'sso';
$loginData['gateway'] = '1';
$loginData['from'] = 'null';
$loginData['savestate'] = '30';
$loginData['useticket'] = '0';
$loginData['pagerefer'] = '';
$loginData['vsnf'] = '1';
$loginData['su'] = base64_encode($u);
$loginData['service'] = 'sso';
$loginData['sp'] = $password;
$loginData['sr'] = '1920*1080';
$loginData['encoding'] = 'UTF-8';
$loginData['cdult'] = '3';
$loginData['domain'] = 'sina.com.cn';
$loginData['prelt'] = '0';
$loginData['returntype'] = 'TEXT';
//var_dump($loginData);exit;
$login = json_decode(loginPost($loginUrl,$loginData),true);
var_dump($login);exit;function loginPost($url,$data){
global $cookie_file ;
//echo $cookie_file ;exit;
$tmp = '';
if(is_array($data)){
foreach($data as $key =>$value){
$tmp .= $key."=".$value."&";
}
$post = trim($tmp,"&");
}else{
$post = $data;
}
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$post);
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file);
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file);
$return = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
return $return;
}

返回的是一个json数据转成数组即可

复制代码 代码如下:
array (size=4)
  'retcode' => string '0' (length=1)
  'uid' => string '1920109964' (length=10)
  'nick' => string '毕姥爷讲故事' (length=18)
  'crossDomainUrlList' =>
    array (size=2)
      0 => string 'https://passport.weibo.com/wbsso/login?ticket=ST-MTkyMDEwOTk2NA%3D%3D-1403228192-gz-AB37DC0C18BA3BFCD90AEFAC6115149D&ssosavestate=1434764192' (length=140)
      1 => string 'https://crosdom.weicaifu.com/sso/crosdom?action=login&savestate=1434764192' (length=74)

这个时候说明我们登录成功了,但是其实我们的微博首页的地址并不是weibo,com,而是 http://weibo.com/bipeng0405/home?wvr=5 这样地址,我们怎么获取这个地址了,很简单,直接抓取weibo。com然后他会自动给你跳转回去的,你只需要把跳转的地址记录下来即可

复制代码 代码如下:
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://weibo.com");
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file);
$return = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

这里还有一个问题,这个时候你可能发现没有跳转到自己微博的首页,这是什么原因呢,可以看看登陆时候有两个连接地址,其中有一个weibo域下的一个地址,猜测应该是进行了cookie的设置所以先获取一边他吧。

复制代码 代码如下:
get($login['crossDomainUrlList'][0]);

这个代码要在刚才weibo.com获取之前,否则会出现问题的。

希望本文所述对大家的PHP程序设计有所帮助。
