PHP Curl simulates logging into the WeChat public platform and Sina Weibo example code, curl example

Open the curl configuration before using curl. The specific method can be found on Baidu. Turn on the curl extension. The password is encrypted with md5. This has been successfully tested. Just change the user and password to yours.

The following code introduces how PHP uses curl to simulate logging into the WeChat public platform. The specific code is as follows:

<&#63;php 
//模拟微信登入 
$cookie_file = tempnam('./temp','cookie'); 
$login_url = 'https://mp.weixin.qq.com/cgi-bin/login'; 
$pwd = md5("********");
$data = "f=json&imgcode=&pwd=$pwd&username=*****@***.com"; 
$ch = curl_init($login_url); 
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); 
curl_setopt($ch,CURLOPT_POST,1); 
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false); 
curl_setopt($ch,CURLOPT_REFERER,'https://mp.weixin.qq.com'); 
curl_setopt($ch,CURLOPT_POSTFIELDS,$data); 
$content = curl_exec($ch); 
curl_close($ch); 
$newurl = json_decode($content,1); 
//var_dump($newurl);
//exit;
$newurl = $newurl['redirect_url']; 
//获取登入后页面的源码 
$go_url = 'https://mp.weixin.qq.com'.$newurl; 
$ch = curl_init($go_url); 
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); 
curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file); 
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,0); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
$content = curl_exec($ch); 
//var_dump(curl_error($ch)); 
print_r($content); 
curl_close($ch);

Use PHP CURL to simulate logging into Sina Weibo

Sometimes we get some Sina Weibo data, but we don’t want to use the API, so we have to use simulated login.

I found that the CURL simulation login code that could be used before was invalid. I Googled it and found that many people had encountered this problem. But I couldn’t find a solution, so I did some research myself and found the reason.

It may be because Sina restricts simulated login. With the same login parameters, everything is normal when logging in through the web page, but when logging in using CURL, the returned COOKIES are temporary.

So it seems that the login was successful and the user information was obtained, but the status is still not logged in when accessing again. My solution is relatively simple, just modify the validity of COOKIES directly.

Attached is the PHP code that I tested and passed as follows. I hope it will be useful to friends who have the same problem. If you have a better solution, please share it.

I found that as long as the CURLOPT_COOKIESESSION parameter is not set, there is no need to modify COOKIE_FILE.

<&#63;php
class sina
{
/*
一个简单的新浪微搏curl模拟登录类. 来源: http://chenall.net/post/sina_curl_login/
使用方法:
http函数是一个简单的curl封装函数,需要自己去实现,
http函数原型如下:
http($url,$post_data = null)
返回网页内容.
第一个参数$url,就是要访问的url地址,$post_data是post数据,如果为空,则代表GET访问.
1.使用加密后密码登录 加密方法: sha1(sha1($pass))
$sina = new sina($username,$sha1pass)
2.直接使用原始密码登录
$sina = new sina($username,$sha1pass,0)
执行之后如果$sina->status非空,则登录成功,否则登录失败.
登录成功之后,你就可以直接继续使用http函数来访问其它内容.
使用 unset($sina) 会自动注销登录.

public $status;
function __construct($su,$sp,$flags = 1) {
$this->status = $this->login($su,$sp,$flags);
}
function __destruct()
{
//注销登录
$this->logout();
}
function logout()
{
http("http://weibo.com/logout.php");
unset($this->status);
}
/*不需要了,只要不设置HTTP函数中不设置CURLOPT_COOKIESESSION参数就行了,要设可以设为false.
function ResetCookie()//重置相关cookie
{
global $cookie_file;
$str = file_get_contents($cookie_file);
$t = time()+3600;//设置cookie有效时间一个小时
$str = preg_replace("/\t0\t/", "\t".$t."\t", $str);
$f = fopen($cookie_file,"w");
fwrite($f,$str);
fclose($f);
}

function login($su,$sp,$flags = 0)
{
$su = urlencode(base64_encode($su));
$data = http("http://login.sina.com.cn/sso/prelogin.php&#63;entry=miniblog&client=ssologin.js&user=".$su);
if (empty($data))
return null;
//$data = substr($data,35,-1);
$data = json_decode($data);
