1、首先进入和风天气开发平台，点击右上角的注册进行注册
和风天气开发平台

2、填写注册用的邮箱和密码完成注册，可能还需要手机号，按提示注册完成即可。
3、从和风天气开发平台右上角进入控制台，输入你刚刚注册用的邮箱和密码按登录进入控制台

4、点击应用管理——创建应用

5、选择免费开发版，然后下一步

6、应用名称随便写

7、API要选择WebApi
API要选择WebApi
API要选择WebApi
（如果开发安卓或者IOS请无视本条）

8、key的名字，随便写

9、创建完成后就是这样，key下面那一串数字就是你的key，请求其他api时都需要用到这个key，请妥善保存。

官方api文档地址：api文档地址，可以在里面查阅所有api的信息，包括请求方式、参数、响应参数等。
所有api返回信息均为json格式。
以下举例两个常用的Api：
GeoApi的使用，用于查询城市的id等信息（这里使用POSTMAN进行测试），每天50000次限制
https://geoapi.qweather.com/v2/city/lookup?key=这里填你的key&location=要查询的城市名字
参数中key为上面的那个key，location为要查询的城市信息，以福州市为例

在body中就是api返回的福州市及其下属行政区域的信息，通常来说，我们只需要location中的第一个城市信息，此处为福州市，记下它的id 101230101

"code": "200",
    "location": [
        {
            "name": "福州",
            "id": "101230101",
            "lat": "26.07530",
            "lon": "119.30623",
            "adm2": "福州",
            "adm1": "福建省",
            "country": "中国",
            "tz": "Asia/Shanghai",
            "utcOffset": "+08:00",
            "isDst": "0",
            "type": "city",
            "rank": "11",
            "fxLink": "http://hfx.link/34w1"
        },...（其余信息省略）

三日天气api的使用：https://devapi.qweather.com/v7/weather/3d?key=这里填你的key&location=要查询的城市的id
id可以通过上面的GeoApi来查询，免费用户每天可以查询1000次
查询效果：
daily中包含三日内的城市的天气信息
