Send a file

[walslayer]

Hello,

I want to send a simple file to an url.
But i've never found an example to do it.
Could you tell me how to send a file via Requests Class.

Thanks in advance.

Kind regards.

要使用 钩子,类似这样:

$hooks = new Requests_Hooks();
$hooks->register('curl.before_send', function($fp, $data=array(
    "file" => "@/Applications/XAMPP/xamppfiles/htdocs/Public/Work/image/icon.png"
    )){
    curl_setopt($fp, CURLOPT_POSTFIELDS, $data);
});
$response = Requests::post($url, $headers, array(), array('hooks' => $hooks));

I was wondering about this too. I ended up using another library, but thank you jskit2015 for your solution.
I think it would be beneficial if you could send a file without having to use hooks.

That's a lot for sending a file!

This tiny lack is against the simplicity aim of the interface and makes the whole thing useless IMO.

This is a duplicate of #34. Working on it right now!

In case you are using php 5.6+ or in my case php 7.1, you need to use curlFile and set CURLOPT_SAFE_UPLOAD to true.
This is the class I use to utilize this library. Passing $files array separately from $body helps out with sending the request with files and regular post data.

<?php

require_once __DIR__ . '/../Requests/Requests.php';
Requests::register_autoloader();

class SBW_Client {

    /**
     * Sonic boom API Request helper
     * @todo add file upload functionality
     * @param string $method
     * @param string $uri
     * @param array $body
     * @param array $headers
     * @return Buzz\Message\Response
     * @throws Exception
     */
    public static function request(string $method, string $uri = null, array $body = [], array $headers = [], array $files = []) {
        $method = strtolower($method);


        // preparing full uri
        $uri = self::getAbsoluteUri($uri);

        $hooks = [];

        // checking requested method to make sure a wrong method is not get called
        // feel free to add more methods in case we start to use another http method
        switch ($method) {
            case 'post':
                // if it is a multipart forma data form
                if (count($files) > 0) {
                    // replacing file paths with curlFile Object
                    array_walk($files, function($filePath, $key) use(&$body) {
                        $body[$key] = new \CURLFile(realpath($filePath));
                    });

                    // starting to add a hook to attach file to request
                    $hooks = new Requests_Hooks();
                    $hooks->register('curl.before_send', function($fp) use ($body) {
                        curl_setopt($fp, CURLOPT_SAFE_UPLOAD, true);
                        curl_setopt($fp, CURLOPT_POSTFIELDS, $body);
                    });
                    $hooks = ['hooks' => $hooks];
                    // no need to set the body, it's taken care of by hooks
                    $body  = [];
                }
            case 'put':
            case 'patch':
            case 'delete':
                $response = Requests::$method($uri, $headers, $body, $hooks);
                break;
            case 'get':
                if (!empty($body)) {
                    $uri .= '?' . http_build_query($body);
                }
                $response = Requests::get($uri, $headers);
                break;
            default:
                throw new Exception("Method $method is not allowed!");
                break;
        }

        return $response;
    }

    /**
     * Returns absolute uri to the api resource
     * @param string $uri
     * @return string
     */
    protected static function getAbsoluteUri(string $uri = null) {
        return PLACE_YOUR_API_PROTOCOL_AND_BASE_URI
                . DIRECTORY_SEPARATOR
                . trim($uri, '/');
    }
