cURL 包含无效的 cURL 选项

Question

我正在从 PHP 7.4 升级到 PHP 8，突然这个错误出现在我的 cURL 请求中：

Fatal error: Uncaught ValueError: curl_setopt_array(): Argument #2 ($options) contains an invalid cURL option in ...

我使用以下代码来构建curl：

$options = array (
    "CURLOPT_POST" => true,
    "CURLOPT_HEADER" => true,
    "CURLOPT_URL" => "https://example.example.com/api/example.php",
    "CURLOPT_FRESH_CONNECT" => true,
    "CURLOPT_RETURNTRANSFER" => true,
    "CURLOPT_FORBID_REUSE" => true,
    "CURLOPT_TIMEOUT" => 10,
    "CURLOPT_FAILONERROR" => true,
    "CURLOPT_POSTFIELDS" => $this->buildPostFields($postData),        
    "CURLOPT_HTTPAUTH" => "CURLAUTH_BASIC",
    "CURLOPT_SSL_VERIFYPEER" => false //REMOVE IN PRODUCTION, IGNORES SELFSIGNED SSL            
);            
$ch = curl_init();
curl_setopt_array($ch, $options);

目标文件始终是 php 扩展名。'buildPostFields' 返回数据数组。

可能出现此错误是因为我的 php 升级到版本 8，但我在文档中找不到任何提示。我尝试删除每一行，然后再试一次。但这没有帮助。

该错误是因为您用双引号引起来的常量。

curl_setopt_array (CurlHandle $handle, array $options) : bool

options
一个数组，指定要设置的选项及其值。键应该是有效的curl_setopt()常量或其整数等价物。

所以应该是CONSTANT_NAME => value

$options = array (
    CURLOPT_POST => true,
    CURLOPT_HEADER => true,
    CURLOPT_URL => "https://example.example.com/api/example.php",
    CURLOPT_FRESH_CONNECT => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FORBID_REUSE => true,
    CURLOPT_TIMEOUT => 10,
    CURLOPT_FAILONERROR => true,
    CURLOPT_POSTFIELDS => $this->buildPostFields($postData),           
    CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
    CURLOPT_SSL_VERIFYPEER => false //REMOVE IN PRODUCTION, IGNORES SELFSIGNED SSL            
);            
$ch = curl_init();
curl_setopt_array($ch, $options);
