PHP中的HTTP PUT請求

Question

如何使用JSON字符串{“ key”：“ la09823”，“ content”：“ jfkdls”}使帶有Random-Header和REQUEST-BODY的PUT HTTP REQUEST到（ http://sample.com:8888/folder ） HTTP狀態碼200 OK會很好。 對不起，我的第一個套接字令人困惑的php代碼：D <3。 謝謝

<?php
$json = "\{\"key\": \"la09823\", \"content\": \"jfkdls\"}";
$hostname="http://sample.com/folder");
$port = 8888;
$timeout = 50;
$socket = socket_create(AF_INET, SOCK_STREAM, tcp);
socket_connect($socket, $hostname, $port);
$text = "PUT /folder/json.txt" HTTP/1.1\n";
$text .= "Host: WhoIAm.com\n";
$text .= "Content-Type: application/json\n";
$text .= "Content-length: " . strlen($json) . "\n";
$finish = $text + $json;
socket_write($socket, $finish, 0);
socket_close($socket);


?>

Answer 1

不要使用原始套接字發出HTTP請求。 有很多更好的庫，例如cURL：

<?php

$data = [
    "key" => "la09823",
    "content" => "jfkdls",
];

$req = curl_init();
curl_setopt_array($req, [
    CURLOPT_URL            => "https://httpbin.org/put",
    CURLOPT_CUSTOMREQUEST  => "PUT",
    CURLOPT_POSTFIELDS     => json_encode($data),
    CURLOPT_HTTPHEADER     => [ "Content-Type" => "application/json" ],
    CURLOPT_RETURNTRANSFER => true,
]);

$response = curl_exec($req);
print_r($response);

（我已經使用httpbin來測試此代碼。顯然，您將在此處使用其他URL。）
