## 安装

```sh
$ composer require chuckpac/weather -vvv
```

## 配置

在使用本扩展之前，你需要去 [高德开放平台](https://lbs.amap.com/dev/id/newuser) 注册账号，然后创建应用，获取应用的 API Key。


## 使用

```php
use Chuckpac\Weather\Weather;

$key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxx';

$weather = new Weather($key);
```

###  获取实时天气

```php
$response = $weather->getLiveWeather('深圳');
```

    "status": "1",
    "count": "1",
    "info": "OK",
    "infocode": "10000",

                    "date": "2018-08-24", 
                    "week": "5", 
                    "dayweather": "雷阵雨", 
                    "nightweather": "雷阵雨", 
                    "daytemp": "31", 
                    "nighttemp": "26", 
                    "daywind": "无风向", 
                    "nightwind": "无风向", 
                    "daypower": "≤3", 
                    "nightpower": "≤3"
                }
            ]
        }
    ]
}
```

### 获取 XML 格式返回值

以上两个方法第二个参数为返回值类型，可选 `json` 与 `xml`，默认 `json`：

```php
$response = $weather->getLiveWeather('深圳', 'xml');
```

示例：

```xml
<response>
    <status>1</status>
    <count>1</count>
    <info>OK</info>
    <infocode>10000</infocode>
    <lives type="list">
        <live>
            <province>广东</province>
            <city>深圳市</city>
            <adcode>440300</adcode>
            <weather>中雨</weather>
            <temperature>27</temperature>
            <winddirection>西南</winddirection>
            <windpower>5</windpower>
            <humidity>94</humidity>
            <reporttime>2018-08-21 16:00:00</reporttime>
        </live>
    </lives>
</response>
```

### 参数说明

```
array | string   getLiveWeather(string $city, string $format = 'json')
array | string   getForecastsWeather(string $city, string $format = 'json')
```

> - `$city` - 城市名/[高德地址位置 adcode](https://lbs.amap.com/api/webservice/guide/api/district)，比如：“深圳” 或者（adcode：440300）；
> - `$format`  - 输出的数据格式，默认为 json 格式，当 output 设置为 “`xml`” 时，输出的为 XML 格式的数据。


### 在 Laravel 中使用

在 Laravel 中使用也是同样的安装方式，配置写在 `config/services.php` 中：

```php
    .
    .
    .
     'weather' => [
        'key' => env('WEATHER_API_KEY'),
    ],
```

然后在 `.env` 中配置 `WEATHER_API_KEY` ：

```env
WEATHER_API_KEY=xxxxxxxxxxxxxxxxxxxxx
```

可以用两种方式来获取 `Chuckpac\Weather\Weather` 实例：

#### 方法参数注入

```php
    .
    .
    .
    public function edit(Weather $weather) 
    {
        $response = $weather->getLiveWeather('深圳');
    }
    .
    .
    .
```

#### 服务名访问

```php
    .
    .
    .
    public function edit() 
    {
        $response = app('weather')->getLiveWeather('深圳');
    }
    .
    .
    .

```
