# 基于词性分析和魅族天气的天气查询机器人
本文将基于 [`jieba-php`](https://github.com/fukuball/jieba-php) 中文分词库以及 [魅族天气 API](https://github.com/shichunlei/-Api/blob/master/MeizuWeather.md) 开发一个天气查询机器人。
## 结果演示

尾部的随机表情并非本教程的一部分。
## 逻辑编写
[`jieba-php`](https://github.com/fukuball/jieba-php) 是目前比较好用的中文分词库,虽然最近的维护并不活跃,但已足够我们的需求:
```shell
composer require fukuball/jieba-php:dev-master
```
以下代码使用了本文作者自行编写的天气查询库,需要进行引入:
```shell
composer require sunxyw/weather
```
您也可以将以下代码自行改写为直接调用魅族天气 API详情请参阅[魅族天气 API 文档](https://github.com/shichunlei/-Api/blob/master/MeizuWeather.md)。
```php
<?php
namespace Bot\Module\SmartChat;
use Fukuball\Jieba\Jieba;
use Fukuball\Jieba\Posseg;
use Sunxyw\Weather\Weather;
use ZM\Annotation\CQ\CQCommand;
use ZM\Console\Console;
class WeatherReport
{
/**
* 加载字典
*
* @OnStart(worker_id=-1)
*
* @return void
*/
public function initDictionary(): void
{
// 分词以及词性分析需要载入字典到内存
ini_set('memory_limit', '600M');
Jieba::init(['dict' => 'small']);
Posseg::init();
}
/**
* 查询天气
*
* @CQCommand(keyword="天气")
*
* @return string
*/
public function cmdQueryWeather(): string
{
// 分词并进行词性分析
$seg_list = Posseg::cut(ctx()->getMessage());
$tags = array_column($seg_list, 'tag');
// 找出词性为 ns地名的单词
$location_index = array_search('ns', $tags, true);
$location = $seg_list[$location_index]['word'];
// 此处引入了本文作者自己写的天气库
$w = new Weather();
try {
$report = $w->getWeather($location);
} catch (\InvalidArgumentException) {
return '城市输入错误';
} catch (\JsonException $e) {
Console::warning("天气查询失败:{$e->getMessage()}");
return '天气查询失败';
}
$template = <<<EOF
%s天气%s
温度:%s℃
湿度:%s%%
风向:%s %s
空气质量:%s
------------------------------
未来三天天气:
%s%s日间%s℃夜间%s℃吹%s %s

EOF;
$args = [
$report->getCity(),
$report->getRealtime()['weather'],
$report->getRealtime()['temperature'],
$report->getRealtime()['humidity'],
$report->getRealtime()['wind_direction'],
$report->getRealtime()['wind_speed'],
$report->getRealtime()['air_quality'],
];
foreach (array_slice($report->getForecastDaily(), 0, 3) as $forecast) {
$args[] = $forecast['date'];
$args[] = $forecast['weather'];
$args[] = $forecast['temperature']['day'];
$args[] = $forecast['temperature']['night'];
$args[] = $forecast['wind_direction'];
$args[] = $forecast['wind_speed'];
}
return vsprintf($template, ...$args);
}
}
