Instagram以编程方式登录 [英] Instagram login programmatically
问题描述
我正在尝试通过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尚不支持登录).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.
我不断收到消息，指出该页面无法加载，并且可能需要启用Cookie.
I keep getting the message that the page could not be loaded and that I might need to enable cookies.
是否可以通过PHP以编程方式登录到Instagram?
Is there any way possible to login programmatically via PHP to Instagram?
这是我到目前为止所拥有的.
This is what I have so far.
$ch = curl_init('https://instagram.com/accounts/login/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);
preg_match_all('/^Set-Cookie:\s*([^\r\n]*)/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
我非常感谢@FatihKısa的代码，做得很好.我已经尝试过此代码，但由于某些Instagram服务器端更改，目前暂时不起作用.我用他的代码玩了2天，并强迫我进行一些小的更改. 此代码非常重要的部分是，Instagram仅接受带有curl引荐来源网址的帖子形式，其中包含cookie数据(csrftoken和mid).同样重要的是，您必须使用 https://www.instagram.com/accounts/login /?force_classic_login ，仅用于WWW，并在cookie创建后删除有关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
#此文件由libcurl生成！编辑风险自负.
#This file was generated by libcurl! Edit at your own risk.
这是工作代码，请尽情享受！
