CENTOS 7 - 卷曲PHP5 cli和无效的Content-Length

问题描述 投票：2回答：2

在PHP脚本中的CENTOS 7 php5（cli）和curl模块中，我尝试在php脚本中使用REST API制作POST（JSON），并且在我的CENTOS 7主机上使用PHP得到了一个奇怪的行为。

这是脚本的输出：

[+] API GLPI : Session Initializing 
   User Token  ===> YsYJnd81WFiFIJ0pqdW6GqiujUpfkH12tdlgYElj 
   Init Url ===> http://192.168.158.129:8080/apirest.php/initSession/* About     to

注意：Content-Length设置为-1

服务器回复我

向POST添加有效负载，因为如果没有帖子内容，curl将添加-1内容长度，具体取决于您使用的curl版本。更高版本将添加0长度内容长度标头，这可能是您看到不同计算机之间的变化的原因。

$payloadJson = json_encode([]);
curl_setopt($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);

而我没有数据要POST！通过将其更改为解决问题

curl_setopt($ch, CURLOPT_POST, 0);

然而，它表明我们应该非常小心这个卷曲库，因为它可以有显着的差异
