案例：

<?php

namespace App\Http\Controllers;

use GuzzleHttp\RequestOptions;

class TestController extends Controller
{
    protected $headers = [];

    public function __construct()
    {
        $this->headers = [
            'time' => time(),
        ];
    }

    public function index()
    {
        $uri = 'http://scrm.xcyc.com/api/test';

        $params['a'] = 1;
        $params['b'] = 2;

        $options = [
            RequestOptions::TIMEOUT => 3,
            RequestOptions::HTTP_ERRORS => false,
            RequestOptions::HEADERS => $this->headers,
            RequestOptions::QUERY => $params,
        ];

        $client = new \GuzzleHttp\Client();
        $res = $client->request('POST', $uri, $options);

        $contents = $res->getBody()->getContents();

        // 失败的情况
        if ($res->getStatusCode() != 200) {
            throw new \Exception(__('心诚直销网服务请求失败'), $res->getStatusCode());
        }

        return json_decode($contents, true);
    }
