新手上路，请多包涵

您好，我正在测试端点，当我运行 php testing.php 时出现此错误。任何帮助将不胜感激。

Fatal error: Uncaught exception 'Guzzle\Http\Exception\CurlException' with message '[curl] 7: Failed to connect to localhost port 8000: Connection refused [url] http://localhost:8000/api/programmers' guzzle\guzzle\src\Guzzle\Http\Curl\CurlMulti.php:359 ...

我也试过 127.0.0.1 但没用

这里是 testing.php

 <?php

require __DIR__.'/vendor/autoload.php';

use Guzzle\Http\Client;

// create our http client (Guzzle)
$client = new Client('http://localhost:8000', array(
    'request.options' => array(
        'exceptions' => false,
    )
));

$nickname = 'ObjectOrienter'.rand(0, 999);
$data = array(
    'nickname' => $nickname,
    'avatarNumber' => 5,
    'tagLine' => 'a test dev!'
);

$request = $client->post('/api/programmers', null, json_encode($data));
$response = $request->send();

echo $response;
echo "\n\n";
