在 PHP cURL 中设置 CURLOPT_POSTFIELDS 时出现错误请求

Question

PHP版本：8.1

通过 PHP cURL 使用 Cloudflare Stream 时，我收到 400 Bad Request 错误，但前提是设置了 CURLOPT_POSTFIELDS。

我的代码：

$tokench = curl_init();
curl_setopt($tokench, CURLOPT_URL, "https://api.cloudflare.com/client/v4/accounts/".getenv("CLOUDFLARE_ACCOUNT")."/stream/".urlencode($_GET["video"])."/token");
 curl_setopt($tokench, CURLOPT_POST, 1);
 curl_setopt($tokench, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($tokench, CURLOPT_HTTPHEADER, ["Authorization: Bearer ".getenv("CLOUDFLARE_TOKEN"), "Content-Type: application/json"]);
 curl_setopt($tokench, CURLOPT_POSTFIELDS, "downloadable=true");
 $tokenraw = curl_exec($tokench);
 curl_close($tokench);
 $tokenarr = json_decode($tokenraw, true);

$tokenarr["success"] 是假的。

我自己修好了。 我必须对 POSTFIELDS 进行 JSON 编码，因为内容类型是 application/json。 代码示例：

$tokench = curl_init();
curl_setopt($tokench, CURLOPT_URL, "https://api.cloudflare.com/client/v4/accounts/".getenv("CLOUDFLARE_ACCOUNT")."/stream/".urlencode($_GET["video"])."/token");
curl_setopt($tokench, CURLOPT_POST, 1);
curl_setopt($tokench, CURLOPT_RETURNTRANSFER, true);
curl_setopt($tokench, CURLOPT_HTTPHEADER, ["Authorization: Bearer ".getenv("CLOUDFLARE_TOKEN"), "Content-Type: application/json"]);
curl_setopt($tokench, CURLOPT_POSTFIELDS, json_encode(["downloadable" => true]));
$tokenraw = curl_exec($tokench);
curl_close($tokench);
$tokenarr = json_decode($tokenraw, true);

$tokenarr["success"] 是真的！
