REST API服務：如何通過PHP curl正確調用它？

Question

假設我有一個正在運行的服務API，該API響應以下網址：

http://example.com/param/1

它同時在get和post動詞上使用。 參數= 1是考慮的參數

如何正確執行curl請求以傳遞參數（POST）？

如果我瀏覽： http : //example.com/param/1我將獲得預期的響應（GET）

但是，如果我執行以下操作，它將無法正常工作：

$service_url = 'http://example.com/';
$curl = curl_init($service_url);
$curl_post_data = array('param'=>1);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
$curl_response = curl_exec($curl);
if ($curl_response === false) {
    $info = curl_getinfo($curl);
    curl_close($curl);
    die('error occured during curl exec. Additional info: ' . var_export($info));
}
curl_close($curl);
$decoded = json_decode($curl_response);
if (isset($decoded->response->status) && $decoded->response->status == 'ERROR') {
    die('error occured: ' . $decoded->response->errormessage);
}
echo 'response ok!';
var_export($decoded->response);

即使像下面那樣更改它也不起作用：

$service_url = 'http://example.com/param/1';
$curl = curl_init($service_url);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
$curl_response = curl_exec($curl);
if ($curl_response === false) {
    $info = curl_getinfo($curl);
    curl_close($curl);
    die('error occured during curl exec. Additional info: ' . var_export($info));
}
curl_close($curl);
$decoded = json_decode($curl_response);
if (isset($decoded->response->status) && $decoded->response->status == 'ERROR') {
    die('error occured: ' . $decoded->response->errormessage);
}
echo 'response ok!';
var_export($decoded->response);

相反，這可行：但是我想它仍然是一個GET

$service_url = 'http://example.com/param/1';
$curl = curl_init($service_url);
$curl_response = curl_exec($curl);
if ($curl_response === false) {
    $info = curl_getinfo($curl);
    curl_close($curl);
    die('error occured during curl exec. Additional info: ' . var_export($info));
}
curl_close($curl);
$decoded = json_decode($curl_response);
if (isset($decoded->response->status) && $decoded->response->status == 'ERROR') {
    die('error occured: ' . $decoded->response->errormessage);
}
echo 'response ok!';
var_export($decoded->response);

$service_url = 'http://example.com/param/1';     
$ch = curl_init($service_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "param1=value1&param2=value2&..");
$response = curl_exec($ch);
curl_close($ch);
