Instagram登录程序 [英] Instagram login programatically
本文介绍了Instagram登录程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想通过我自己的网站以编程方式登录到Instagram，因为我想从Instagram检索直接消息（这需要一个登录，因为它不支持在Instagram的API（还））。但是Instagram的登录页面需要cookie才能登录。
我一直收到无法加载网页的消息，我可能需要启用Cookie。
有什么办法可以通过PHP以编程方式登录到Instagram吗？
这是我到目前为止。
$ 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\\\
] *）/ 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/'）;

解决方案
我非常尊重@FatihKısa的代码，非常好的工作。我试过这个代码，但现在它不工作，可能是因为一些Instagram服务器端的更改。我已经玩了2天他的代码，并强迫它与我的小变化。
这段代码的非常重要的部分是，Instagram只接受包含cookie数据（csrftoken和mid）的curl referrer的post形式。另一个重要的部分是您必须使用 https://www.instagram.com/accounts/login/ ？force_classic_login ，仅限于使用WWW并在Cookie创建关于curl info的字符串后删除：
#Netscape HTTP Cookie文件
#http：//curl.haxx.se/docs/http-cookies.html
＃此文件由libcurl生成！

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.
I keep getting the message that the page could not be loaded and that I might need to enable cookies.
Is there any way possible to login programmatically via PHP to Instagram?
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);
解决方案
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 File
#http://curl.haxx.se/docs/http-cookies.html
#This file was generated by libcurl! Edit at your own risk.
Here is working code, enjoy!
