Question

我想知道您是否可以使用PHP为cCURL请求提供一些代码，我正在尝试从fpl api检索显示联盟排名的数据。联赛排名api的网址为-https://fantasy.premierleague.com/api/leagues-classic/my_league_id/standings/?page_new_entries=1&page_standings=1，我可以通过浏览器查看数据，但是当我尝试使用PHP的curl请求检索数据时，它返回403错误，并显示消息“身份验证凭据未提供”提供”。那意味着我将需要登录凭据来检索它。

在使用开发人员工具和邮递员对其进行研究之后，我现在知道我需要通过登录获取csrf令牌，然后保存该令牌以在提出联盟排名请求时使用。我不知道该怎么做，我可以，但是如果有人可以帮我忙，我将不胜感激。

我需要做的是使用此表单数据向https://users.premierleague.com/accounts/login/发送POST请求-

"login"         => "my_email",
"password"      => "my_password",
"app"           => "plfpl-web",
"redirect_uri"  => "https://fantasy.premierleague.com/",

发出请求后，我需要捕获csrf令牌cookie，我相信它将在名为“ csrfmiddlewaretoken”的隐藏输入中并将其保存在变量中。

获取令牌并将其保存后，我将向https://fantasy.premierleague.com/api/leagues-classic/my_league_id/standings/发出GET请求，将保存的csrf令牌变量放入标头中，然后对数据进行json解码，以便能够回显联赛详细信息。

我很确定这是怎么做的，但是我对PHP的了解不是那么好，并且想知道那里是否有任何风味可以帮助一个兄弟。任何帮助将不胜感激：）

我从第一部分开始，提出了最初的发布请求，但是在返回令牌方面没有运气。到目前为止，这是我的代码-

<?php

$cookie = "cookies.txt";
$url = 'https://users.premierleague.com/accounts/login/';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);

// var_dump($response);

$dom = new DOMDocument;
@$dom->loadHTML($response);

$tags = $dom->getElementsByTagName('input');
for($i = 0; $i < $tags->length; $i++) {
    $grab = $tags->item($i);
    if($grab->getAttribute('name') === 'csrfmiddlewaretoken') {
        $token = $grab->getAttribute('value');
    }
}

echo $token;

?>

<?php

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
