如何使用php和curl登录Instagram并获取sessionid？

标签： php curl cookies instagram session-cookies

我在这个问题的答案中使用了这个PHP代码： Instagram login programmatically 当我检查cookie.txt时，sessionid是＆＃34;＆＃34; 。有没有办法可以更改此代码以使其获得sessionid cookie？ csrftoken，rur，mid，urlgen似乎都设置正确，但我不知道......我需要sessionid以编程方式探索标签。

编辑：问题出在我的用户名和密码上，我被引导到＆＃34;可疑的登录尝试＆＃34;页。 ＆＃34;我们检测到异常登录尝试 为确保您的帐户安全，请告诉我们您是否是＃34; 编辑：我的一个帐户每次都在工作，只有另一个显示＆＃34;可疑的登录尝试＆＃34;页。 ??? ：/ ???

编辑：问题是我的用户名和密码我被定向到“可疑登录尝试”页面。 “我们检测到异常登录尝试为了保护您的帐户，请告诉我们您是否是”

Facebook / Instagram（正确地）检测到你试图违反他们的服务条款，这禁止了这类事情，因此设置了一个障碍，可能需要你做一些像解决CAPTCHA这样的事情。 / p>

您应该使用the official Instagram API代替。

变化

$cookieFileContent = str_replace('sessionid=; ', '', $cookieFileContent);

的

$cookieFileContent = str_replace('sessionid=""; ', '', $cookieFileContent);

添加

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

您将登录。

有效：

}

此功能通过url返回Instagram页面：

function curl_inst($url) { 

    $arrSetHeaders = array(
        'origin: https://www.instagram.com',
        'authority: www.instagram.com',
        'method: GET',
        'upgrade-insecure-requests: 1',
        'Host: www.instagram.com',
        "User-Agent: USERAGENT",
        'content-type: application/x-www-form-urlencoded',
        'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'accept-language:ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7,uk;q=0.6',
        'accept-encoding: deflate, br',
        "Referer: https://www.instagram.com",
        'Connection: keep-alive',
        'cache-control: max-age=0',
    );
    $ch  = curl_init();
    curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__)."/!instagram/".COOKIE);
    curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__)."/!instagram/".COOKIE);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); //connection timeout in seconds 
    curl_setopt($ch, CURLOPT_USERAGENT, USERAGENT);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $arrSetHeaders);     
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    $page = curl_exec($ch);

    if (!curl_errno($ch)) {
      switch ($http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE)) {
        case 200:  # OK
          //echo 'All OK: ', $http_code, "\n";
          //var_dump($page);    
          curl_close($ch);
          return $page;    
        default:
          echo 'Error: ', $http_code, "\n";
          curl_close($ch);    
          break;    
      }
    }      

}

下一步：

login_inst();
sleep(5);
$page = curl_inst('https://www.instagram.com/explore/tags/stackoverflow/');
var_dump($page);
