HTTPS via Curl JSON response

Question

I am trying to bring back the following page with Curl.

https://api.mercadolibre.com/sites/MLA/search/

How do I do this, being the HTTPS protocol?

Answer 1

<?php
//$url = 'https://api.mercadolibre.com/sites/MLB/search/';
$url = 'https://api.mercadolibre.com/sites/MLB/search?category=MLB1648';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_CAINFO, getcwd() . DIRECTORY_SEPARATOR . 'cacert.pem');

$output = curl_exec($curl);
curl_close($curl);

header('Content-Type: application/json');
echo $output;

The archive cacert.pem must be downloaded at http://curl.haxx.se/ca/cacert.pem and placed in the same folder where the above script is.

NOTE: When using the Free Market API, specify MLB to search for data in the Brazilian version of the site. MLA refers to the Argentine version.

It is also possible to create a function to facilitate a little:

<?php

function get($url) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_CAINFO, getcwd() . DIRECTORY_SEPARATOR . 'cacert.pem');

    $output = curl_exec($curl);
    curl_close($curl);

    return $output;
}

header('Content-Type: application/json');

// Obtém produtos da categoria "Informática"
echo get('https://api.mercadolibre.com/sites/MLB/search?category=MLB1648');

// Obtém as categorias do site;
echo get('https://api.mercadolibre.com/sites/MLB/categories');

// Faz uma busca com a palavra-chave "pendrive"
echo get('https://api.mercadolibre.com/sites/MLB/search?q=pendrive');
