PHP 实现 POST 请求并携带 Cookie

使用 cURL 发送 POST 请求并携带 Cookie

初始化 cURL 会话并设置必要的选项，包括 POST 数据和 Cookie。

$url = 'https://example.com/api';
$postData = ['key1' => 'value1', 'key2' => 'value2'];
$cookieFile = 'cookies.txt';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile);

$response = curl_exec($ch);
curl_close($ch);

echo $response;

使用 file_get_contents 发送 POST 请求并携带 Cookie

通过创建流上下文来发送 POST 请求，并在头信息中包含 Cookie。

$url = 'https://example.com/api';
$postData = http_build_query(['key1' => 'value1', 'key2' => 'value2']);
$cookie = 'cookie_name=cookie_value';

$options = [
    'http' => [
        'method' => 'POST',
        'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
                    "Cookie: $cookie\r\n",
        'content' => $postData
    ]
];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

echo $response;

使用 Guzzle HTTP 客户端发送 POST 请求并携带 Cookie

Guzzle 是一个流行的 PHP HTTP 客户端库，可以方便地发送请求并管理 Cookie。

require 'vendor/autoload.php';

$client = new \GuzzleHttp\Client(['cookies' => true]);
$response = $client->post('https://example.com/api', [
    'form_params' => ['key1' => 'value1', 'key2' => 'value2']
]);

echo $response->getBody();

手动设置 Cookie 头

如果不需要 Cookie 持久化，可以直接在请求头中设置 Cookie。

$url = 'https://example.com/api';
$postData = http_build_query(['key1' => 'value1', 'key2' => 'value2']);
$cookie = 'cookie_name=cookie_value';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ["Cookie: $cookie"]);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
