これは非常に珍しい問題です。httpcomponents と httpurlconnection のテストを作成するだけです。どちらも 3 つのキーと値の文字列ペアを php ファイルに投稿すると、php は 3 つの文字列を結合して戻ります。両方のテストは、仮想マシンの Debian Linux である私自身の Linux サーバーで正常に動作します。ただし、webhostingpad.com によってホストされている自分のサイトに php ファイルをアップロードすると、httpcomponents テストのみが機能します。httpurlconnection の場合、エラー コードとして 403 禁止されます。
誰が私が何をすべきかヒントを持っていますか?
ここに私のファイルがあります：
<?php
$s1 = $_POST['s1'];
$s2 = $_POST['s2'];
$s3 = $_POST['s3'];
echo "$s1 $s2$s3";
