从php执行curl时出错

下面的代码使用POSTMAN可以完美地运行。当我尝试使用postman为PHP生成的代码时，它给了我错误

原始代码：

curl -X POST \
  'http://111.93.2.38:8080/gsp/gsp/authenticate?grant_type=token' \
  -H 'cache-control: no-cache' \
  -H 'gspappid: 64AB7894D61644F3B5CA18B4738C700D' \
  -H 'gspappsecret: 70988876GEEEEG4504GB400G92B801E23686' \

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_PORT => "8080",
  CURLOPT_URL => "http://111.93.2.38:8080/gsp/gsp/authenticate?grant_type=token",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_HTTPHEADER => array(
    "cache-control: no-cache",
    "gspappid: 64AB7894D61644F3B5CA18B4738C700D",
    "gspappsecret: 70988876GEEEEG4504GB400G92B801E23686",
    "postman-token: ff8278bb-b888-9fd3-6a55-780dafd58aa5"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

PHP代码：

curl -X POST \
  'http://111.93.2.38:8080/gsp/gsp/authenticate?grant_type=token' \
  -H 'cache-control: no-cache' \
  -H 'gspappid: 64AB7894D61644F3B5CA18B4738C700D' \
  -H 'gspappsecret: 70988876GEEEEG4504GB400G92B801E23686' \

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_PORT => "8080",
  CURLOPT_URL => "http://111.93.2.38:8080/gsp/gsp/authenticate?grant_type=token",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_HTTPHEADER => array(
    "cache-control: no-cache",
    "gspappid: 64AB7894D61644F3B5CA18B4738C700D",
    "gspappsecret: 70988876GEEEEG4504GB400G92B801E23686",
    "postman-token: ff8278bb-b888-9fd3-6a55-780dafd58aa5"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

您面临什么样的错误，请您分享一下，我们可以帮助您吗？
如果出现超时错误，您可以尝试更改CURLOPT_timeout=>30的值，错误是什么样子的？可能您没有安装并启用cURL
