PHP CURL Using POST Raw JSON Data

问题

I am working with PHP curl for post, for some reason I couldn't post the form successfully.

$ch = curl_init();
$headers = [
            'x-api-key: XXXXXX',
            'Content-Type: text/plain'
        ];
$postData = array (
    'data1: value1',
    'data2: value2'
);
curl_setopt($ch, CURLOPT_URL,"XXXXXX");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);           
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$server_output = curl_exec ($ch);

When I try using the same in post it works, but not with PHP.

var_dump($server_output) ==> string(67) ""require data1 and data2 or check the post parameters""
var_dump(curl_error($ch)) ==> string(0) ""

回答1:

If you wanna use Content-type: application/json and raw data, seem your data should be in json format

$ch = curl_init();
$headers  = [
            'x-api-key: XXXXXX',
            'Content-Type: text/plain'
        ];
$postData = [
    'data1' => 'value1',
    'data2' => 'value2'
];
curl_setopt($ch, CURLOPT_URL,"XXXXXX");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postData));           
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result     = curl_exec ($ch);
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
