laravel服务层使用高德天气的api

1.你要注册一个高德开放平台的账号，创建一个项目，然后获取app_key.

2.下面是将调用的数据封装在了服务层，使用的时候只需要调用这个Services就可以了。

namespace App\Services;

use GuzzleHttp\Client;

class WeatherService
{
    /**
     * @var string
     */
    protected $key;

    /**
     * @var array
     */
    protected $guzzleOptions = [];

    /**
     * Weather constructor.
     *
     */
    public function __construct()
    {
        $this->key = config('app.api_key', 'xxxxxxxxxxxxxx');
    }

    /**
     * @return \GuzzleHttp\Client
     */
    public function getHttpClient()
    {
        return new Client($this->guzzleOptions);
    }

    /**
     * @param array $options
     */
    public function setGuzzleOptions(array $options)
    {
        $this->guzzleOptions = $options;
    }

    /**

     *

     *

     */
    public function getLiveWeather($city, $format = 'json')
    {
        return $this->getWeather($city, 'base', $format);
    }

    {
        return $this->getWeather($city, 'all', $format);
    }

        }
        $query = array_filter([
            'key' => $this->key,
            'city' => $city,
            'output' => $format,
            'extensions' => $type,
        ]);
        try {
            $response = $this->getHttpClient()->get($url, [
                'query' => $query,

        } catch (\Exception $e) {
            throw new \Exception($e->getMessage(), $e->getCode(), $e);
