以编程方式登录 Instagram [英] Instagram login programmatically
问题描述
我正在尝试通过我自己的网站以编程方式登录 Instagram，因为我想从 Instagram 检索直接消息(这需要登录，因为 Instagram API(尚)不支持它).但是 Instagram 登录页面需要 cookie 才能登录.
I'm trying to programmatically login to Instagram via my own website because I want to retrieve direct messages from Instagram (this requires a login as it is not supported in the Instagram API (yet)). But the Instagram login page requires cookies to login.
我不断收到无法加载页面并且我可能需要启用 cookie 的消息.
I keep getting the message that the page could not be loaded and that I might need to enable cookies.
有没有办法通过 PHP 以编程方式登录 Instagram?
Is there any way possible to login programmatically via PHP to Instagram?
这是我目前所拥有的.
$ch = curl_init('https://instagram.com/accounts/login/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);
preg_match_all('/^Set-Cookie:s*([^
]*)/mi', $result, $ms);
$cookies = array();
foreach ($ms[1] as $m) {
list($name, $value) = explode('=', $m, 2);
$cookies[$name] = $value;
}
$ccode = substr($cookies['ccode'], 0, 2);
$mid = array_shift(explode(';', $cookies['mid']));
$csfrtoken = array_shift(explode(';', $cookies['csrftoken']));
$header = array();
$header[] = 'Accept: */*';
$header[] = 'Accept-Encoding: gzip,deflate';
$header[] = 'Accept-Language: nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4';
$header[] = 'Connection: keep-alive';
$header[] = 'Content-Length: 46';
$header[] = 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8';
$header[] = 'X-Instagram-AJAX: 1';
$header[] = 'X-Requested-With: XMLHttpRequest';
$ch = curl_init('https://instagram.com/accounts/login/ajax/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=*****&password=*****&intent=');
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36');
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__).'/test.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__).'/test.txt');
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIE, 'mid='.$mid.'; ccode='.$ccode.'; csrftoken='.$csfrtoken.';');
curl_setopt($ch, CURLOPT_ENCODING, '');
$response = curl_exec($ch);
推荐答案
我非常尊重 @Fatih Kısa 的代码，非常好.我已经尝试过这段代码，但现在它不起作用，可能是因为 Instagram 服务器端的一些更改.我已经用他的代码玩了 2 天，并强制它与我的小改动一起工作.这段代码非常重要的部分是 Instagram 只接受包含 cookie 数据(csrftoken 和 mid)的带有 curl 引用的帖子表单.同样重要的部分是您必须使用 https://www.instagram.com/accounts/login/?force_classic_login，仅用于 WWW 并在创建 cookie 后删除有关 curl 信息的字符串:
My great respect to @Fatih Kısa for his code, very good job. I have tried this code, but for now it doesn't work, probably, because of some Instagram server-side changes. I have played 2 days with his code and force it to work with my small changes. Very important part of this code is that Instagram accepts only post form with curl referrer which contains the cookies data (csrftoken and mid). Also important part is that you must use https://www.instagram.com/accounts/login/?force_classic_login, only with WWW and to remove after cookies creation the strings about curl info:
#Netscape HTTP Cookie 文件
#Netscape HTTP Cookie File
#http://curl.haxx.se/docs/http-cookies.html
#http://curl.haxx.se/docs/http-cookies.html
#这个文件是libcurl生成的！编辑风险自负.
#This file was generated by libcurl! Edit at your own risk.
这是工作代码，享受吧！
