在 PHP 脚本中的 CENTOS 7
php5(cli( 和 curl 模块上，我尝试在 PHP 脚本中使用 REST API 制作 POST (JSON(，结果在 CENTOS 7 主机上遇到了奇怪的 PHP 行为。
下面是脚本的输出：

#1st request to get a Session Token

echo (" User Token ===> " . $usertoken);
$headers = array(

$initurl=$api_url."/initSession/";
echo ("n Init Url ===> " . $initurl);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $initurl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_VERBOSE, true);

# Then 2nd request to Post JSON not shown here
向 POST 添加有效负载，因为如果没有 POST 内容，curl 将根据您使用的 curl 版本添加 -1 内容长度。更高版本将添加一个 0 长度的内容长度标头，这可能是您看到不同计算机之间存在差异的原因。
$payloadJson = json_encode([]);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadJson);
curl_setopt(
$ch,
CURLOPT_HTTPHEADER,
[
"Content-type: application/json",
"Content-Length: ".strlen($payloadJson),
"Authorization: user_token " . $usertoken,
]
);
我发现我的错误让我感到羞耻。在我设置的第一个请求中
curl_setopt($ch, CURLOPT_POST, 1);
而我没有数据可以发布！解决将其更改为的问题
curl_setopt($ch, CURLOPT_POST, 0);
然而，这表明我们应该非常小心这个 curl 库，因为它可以有很大的不同
