curl 模拟登录微信公众平台带验证码

　　这段时间一直写个项目，从切图到前端到后台都要搞定，真tm累。今天下午手残，不停用错误的密码去模拟登录微信公众平台，结果后来出现验证码，瞬间悲剧(菜鸟从来没搞过带验证码的)。

　　研究了一下，发现其实很简单，直接把生成的二维码图片拉过来，让用户自己输入，再提交一遍表单即可。其实中间还是有些坑，比如生成验证码的时候，要把cookie保存下，登录的时候要带上这个cookie，要不然会总是提示需要验证码。

客户端:

 <body>

 <form>

 <p><input type="text" name="user" value="" />帐号</p>

 <p><input type="password" name="pass" value="" />密码</p>

 <div style="display:none">

 <input type="text" name="code" />验证码

 <img src="" id="imgcode" /><a href="javascript:;" id="changCode">换一张</a>

 </div>

 <input type="button" class="submit" value="绑定"/>

 </form>

 <script src="http://code.jquery.com/jquery-1.9.0.js"></script>

 <script type="text/javascript">

 $(function(){

     $('.submit').on('click', function(){

         var user = $('input[name=user]').val(),

             pass = $('input[name=pass]').val();

         var data = {

             'user' : user,

             'pass' : pass

         };

         if ( $('img').attr('src') != '' ) {

             var code = $('input[name=code]').val();

             data.code = code;

         }

         $.post('wx-login.php', data, function(res){

             var oRes = JSON.parse(res);

             //console.log(oRes);

             // -8 需要验证码

             if ( oRes.base_resp.ret == '-8') {

                 $('img').attr('src','code.php?u='+user);

                 $('div').show();

             } else if( oRes.base_resp.ret == 0 ){

                 alert('登录成功');

             } else {

                 alert('登录失败');

             }

         });

     });

     $('#changCode').on('click', function(){

         var user = $('input[name=user]').val();

         $('img').attr('src','code.php?u='+user+'&s='+Math.random(1));

     });

 });

 </script>

 </body>

　　服务端-验证码:

　　code.php

 $username = $_GET['u'];

 $url = "https://mp.weixin.qq.com/cgi-bin/verifycode?username={$username}&r=".time();

 //必须绝对路径

 $file = dirname(__FILE__).'/cookie/cookie_'.$username.'.txt';

 $curl = curl_init();

 curl_setopt($curl, CURLOPT_URL, $url);

 curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, 0 );

 curl_setopt ( $curl, CURLOPT_SSL_VERIFYHOST, 2 );

 curl_setopt ($curl, CURLOPT_TIMEOUT, 10 );

 curl_setopt($curl, CURLOPT_HEADER, 0);

 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($curl, CURLOPT_COOKIEJAR, $file);

 $res = curl_exec ($curl);

 curl_close ( $curl );

 header("Content-type:image/jpeg");

 echo $res;

服务端-登录:

　 wx-login.php

 $arr = array(

     'username'=>$_POST['user'], //wx公众帐号

     'pwd'=>md5($_POST['pass']), //wx公众帐号密码

     'f'=>'json'

 );

 if (isset($_POST['code'])) {

     $arr['imgcode'] = $_POST['code'];

 }

 $file = dirname(__FILE__).'/cookie/cookie_'.$arr['username'].'.txt';

 $headers = array(

     'User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.107 Safari/537.36',

     'Referer:https://mp.weixin.qq.com/',

 );

 $curl = curl_init();

 curl_setopt($curl, CURLOPT_URL, 'https://mp.weixin.qq.com/cgi-bin/login');

 curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, 0 );

 curl_setopt ( $curl, CURLOPT_SSL_VERIFYHOST, 2 );

 curl_setopt ($curl, CURLOPT_TIMEOUT, 10 );

 curl_setopt($curl, CURLOPT_HEADER, 0);

 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_POST, 1);

 curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($arr));

 curl_setopt($curl, CURLOPT_HTTPHEADER,$headers);

 if (!empty($arr['imgcode'])) {

     curl_setopt($curl, CURLOPT_COOKIEFILE, $file);

 }

 $result = curl_exec ($curl);

 curl_close ( $curl );

 echo $result;
