[![NPM](https://nodei.co/npm/weather-ct.png)](https://nodei.co/npm/weather-ct/)
4+
5+
天气预报cli工具(支持中国天气网和和风天气)<br>
6+
7+
该版本可以视为[和风天气](https://github.com/chiwent/weather-hf)的升级版本，引入了中国天气网的源，支持最长7天的天气预报（和风免费用户最多支持3天），并且中国天气网不需要引入开发者key，查询的次数都不限制，这些方面都是优于和风的。不过和风提供的数据类型更多，比如支持能见度，中国天气网不支持。<br>
8+
9+
### 安装
10+
```
11+
npm install -g weather-ct
12+
13+
```
14+
15+
### 参数说明
16+
17+
```
18+
--source / -s : 选择源（1：中国天气网，2：和风天气）,默认是1
19+
--city / -c : 选择目标城市(如果选择了地区可以忽略)
20+
--area / -a : 选择目标地区(如果选择了城市可以忽略)
21+
--opt / -o : 选择查询的模式，目前有now(今天的天气情况)，forecast(未来天气情况).如果选择了1的源，请忽略now选项.如果选择了2的源，默认是now
22+
--lang / -l : 语言，默认为中文，可忽略。如果选择了1的源，请忽略
23+
--key / -k : 开发者key，如果在config.json中已经填了可忽略此选项。如果选择了1的源，请忽略。
24+
```
25+
26+
#### 注意事项
27+
在最开始使用和风源的时候，需要在命令行中加入key配置，它只需要配置一次，后续可以省略key<br>
28+
中国天气网输入的地址需要是汉语拼音，和风支持中文汉字<br>
29+
下面的模式无法使用：<br>
30+
```
31+
$ waethercli -a huadu
32+
```
33+
请使用：<br>
34+
```
35+
$ waethercli -c guangzhou（待查询地区的辖区）
36+
```
37+
38+
39+
### demo
40+
41+
#### 中国天气网（1）
42+
```
43+
$ waethercli -c guangzhou
44+
$ waethercli -c guangzhou -o forecast
45+
$ waethercli -a huadu -o forecast
46+
```
47+
48+
#### 和风天气（2）
49+
```js
50+
$ waethercli -c guangzhou
51+
$ waethercli -c guangzhou -o forecast
52+
$ waethercli -a huadu
53+
$ waethercli -a huadu -o forecast
54+
```
55+
56+
57+
#### 补充
58+
两个源都还没有测试过外国和港澳台<br>
59+
中国天气网的的源有两个，一个可以靠位置的拼音来查询，另外一个只能靠位置的编码来查询，并且在部分地区的命名上也没有统一的标准，有些区直接划为了市，有些区把“区”的称号取消了，让人很难受。所以可能在输入部分地区后会有bug<br>
