使用php以编程方式获取access_token

Question

I have a login and password to connect to a platform. After login from browser I will get an access_token it's stored in cookie (I guess). How to get the access token programmatically using PHP (maybe using cURL) ?

I found a solution but it's written in python, how to do the same with PHP ?

Here is the solution with python

import urllib
import urllib2
import cookielib
import json
import logging


class GISTokenGenerator:
    def __init__(self, email, password):
        self.cj = cookielib.CookieJar()
        self.opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(self.cj))
        self.email = email
        self.login_data = urllib.urlencode({'user[email]': email, 'user[password]': password})

    def generate_token(self):
        logging.info('Generating a token for {0}...'.format(self.email))
        self.opener.open('https://site/users/sign_in', self.login_data)
        for cookie in self.cj:
            if cookie.name == 'aiesec_token':
                token_json = json.loads(urllib.unquote(cookie.value))
                token = token_json['token']['access_token']
        if token is None:
            raise Exception('Unable to generate a token for {0}!'.format(self.email))
        return token

Answer 1

PHP can access cookies via the superglobal variable $_COOKIE . To retrieve a specific cookie, echo $_COOKIE['name_of_cookie']; . To access all cookies, loop through them all

foreach ($_COOKIE as $cookie) {
    echo $cookie;
}

Edit

As I understand it, once your receive this cookie (presumable called access_token ), you want to cURL a page with this cookie.

This is a pretty good resource on how to fetch a URL with cookies. Essentially,

$c = curl_init('http://www.example.com/needs-cookies.php');
curl_setopt($c, CURLOPT_VERBOSE, 1);
curl_setopt($c, CURLOPT_COOKIE, 'access_token=' . $_COOKIE['access_token']);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$page = curl_exec($c);
curl_close($c);
