使用 JSON 发送数据时,cURL php POST 错误 header

cURL php POST error header when send data with JSON

我正在尝试 post 带有 JSON 数据的 cURL 数据,我已经更改了 header 但我遇到了错误,这是我的代码

public static function curlValidation($url, $params) {
    $ch = curl_init();

    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_HEADER, array("Accept:application/json", "Content-Type:application/json"));
    curl_setopt($ch,CURLOPT_POST, true);
    curl_setopt($ch,CURLOPT_POSTFIELDS, $params);

    $result = curl_exec($ch);
    if($result === false)
        return curl_error($ch);

    curl_close($ch);
    return $result;
}

$params 值为 JSON

{
   "NIK":"123",
   "NAMA":"ASD",
   "TGL_LHR":"123",
}

出现这样的错误

'HTTP/1.1 500 Internal Server Error

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS
Access-Control-Allow-Headers: origin, x-requested-with, content-type

{\"msg\":\"Content type \'application/x-www-form-urlencoded;charset=UTF-8\' not supported\",\"error\":false}'

尝试在您的函数中执行此操作 - 我认为您的 headers 数据已损坏:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);

$headers = array();
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);

根据您收到的消息,您发送的内容类型有误。

将您函数中的 curl 行替换为这些行,或者仅将您的 $headers 行替换为本示例中的这 3 行 $headers 行。

这不起作用的原因是你在这行有错误:

curl_setopt($ch,CURLOPT_HEADER, array("Accept:application/json", "Content-Type:application/json"));

您应该使用的常数是 CURLOPT_HTTPHEADER
