It is important to notice that when using curl to post form data and you use an array for CURLOPT_POSTFIELDS option, the post will be in multipart format
<?php
$params=['name'=>'John', 'surname'=>'Doe', 'age'=>36];
$defaults = array(
CURLOPT_URL => 'http://myremoteservice/',
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $params,
);
$ch = curl_init();
curl_setopt_array($ch, ($options + $defaults));
?>
This produce the following post header:
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="name"
Jhon
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="surnname"
Doe
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="age"
36
--------------------------fd1c4191862e3566--
Setting CURLOPT_POSTFIELDS as follow produce a standard post header
CURLOPT_POSTFIELDS => http_build_query($params),
Which is:
name=John&surname=Doe&age=36
This caused me 2 days of debug while interacting with a java service which was sensible to this difference, while the equivalent one in php got both format without problem.
Basic curl example
Una volta che hai compilato PHP con il supporto cURL, puoi iniziare ad usare le funzioni cURL. L'idea di base dietro le funzioni cURL รจ inizializzare una funzione curl utilizzando curl_init(), settarne le opzioni per il trasferimento usando curl_setopt(), successivamente eseguirla con curl_exec() e terminare la session tramite curl_close(). Ecco un esempio che usa le funzioni cURL per scaricare l'homepage di example.com e memorizzarla in un file:
Example #1 Utilizzo del modulo cURL di PHP per scaricare l'homepage di example.com
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
if(curl_error($ch)) {
fwrite($fp, curl_error($ch));
}
curl_close($ch);
fclose($fp);
?>
