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 AppServices;

use GuzzleHttpClient;

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

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

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

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

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

    /**

     * @param string $format
     *
     * @return PsrHttpMessageResponseInterface
     *
     * @throws Exception
     */
    public function getLiveWeather($city, $format = json)
    {
        return $this->getWeather($city, base, $format);
    }

    /**

     * @param string $format

     */

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

            throw new Exception(Invalid response format: .$format);
        }

            throw new Exception(Invalid type value(base/all): .$type);
        }
        $query = array_filter([
            key => $this->key,
            city => $city,
            output => $format,
            extensions => $type,
        ]);
        try {
            $response = $this->getHttpClient()->get($url, [
                query => $query,
            ])->getBody()->getContents();
            return json === $format ? json_decode($response, true) : $response;
        } catch (Exception $e) {
            throw new Exception($e->getMessage(), $e->getCode(), $e);
        }
    }
}
