php - file_get_contents implements POST data, https

Question

As the title states, regardless of the curl method, POST is given to the interface data, but the interface cannot obtain it or there is a problem with returning parameters.

Post the code:

    $POSTFIELDS = array("receipt-data" => $receipt_data);    //
    $POSTFIELDS = json_encode($POSTFIELDS);    // 注释了也没用
    $url = "https://sandbox.itunes.apple.com/verifyReceipt";

    $context = stream_context_create(array(
        'http' => array(
            'method'  => 'POST',
            'header'  => "Content-type: application/x-www-form-urlencoded",
            'content' => http_build_query($POSTFIELDS),
            'timeout' => 20,
        )
    ));
    return file_get_contents($url, false, $context);

$receipt_data data format is correct because curl testing can return correct information.

But for file, the returned parameters are always wrong no matter what. I don’t know what the problem is.

Answer 1

What you said upstairs is correct. Regarding this problem, it is actually an error when interacting with the Apple payment interface and transmitting data.

http_build_query is not required

Answer 2

Let’s first see what the server gets. . . Are you passing json? Then there is the POST in form format. . . Without key=>value, the backend can only get strings in json format

Answer 3

HTTPS needs to enable SSL
