API_Key和城市编码文件获取：
点击此处
注册相关信息之后，按照获取Key的文档创建新的应用：
这里是我们申请到的Key:
然后下载城市编码表格：
下载的表格为：AMap_adcode_citycode_20210406.xlsx，可以看到，北京的城市编码为110000.
代码调用：
需要用到python里的requests包
代码中的url书写格式要按照参数表格去写
如请求参数所描述，parameters代表的参数包括必填参数和可选参数。所有参数均使用和号字符(&)进行分隔。我们在组建url的时候，需要提前将各个参数提前赋值，如，参数key为我们申请的Key，city为城市的编码。
原本的url是：
https://restapi.amap.com/v3/weather/weatherInfo?
只需要在后面将各个参数赋值，加在问号后面，各个参数用&分割，如：
url = f"https://restapi.amap.com/v3/weather/weatherInfo?key={API_KEY}&city={city}&extensions=all&output=JSON"
这部分“key={API_KEY}&city={city}&extensions=all&output=JSON”是我们写入的参数，组成了一个新的url，然后用requests包获取页面信息，返回给response：
import requests
API_KEY = "8f2292423c70b8b79e63af30cd84498a"
city = "110000"
#extensions = "all"
url = f"https://restapi.amap.com/v3/weather/weatherInfo?key={API_KEY}&city={city}&extensions=all&output=JSON"
response = requests.get(url)
data = response.json()
print(data)
返回的内容(json格式)为：
{
"status":"1","count":"1","info":"OK","infocode":"10000","forecasts":[{
"city":"北京市","adcode":"110000","province":"北京","reporttime":"2023-04-18 23:08:57","casts":[{
"date":"2023-04-18","week":"2","dayweather":"晴","nightweather":"晴","daytemp":"27","nighttemp":"9","daywind":"东南","nightwind":"东南","daypower":"≤3","nightpower":"≤3","daytemp_float":"27.0","nighttemp_float":"9.0"},{

用在线JSON工具进行解析：
{
"status": "1",
"count": "1",
"info": "OK",
"infocode": "10000",
"forecasts": [{
"city": "北京市",
"adcode": "110000",
"province": "北京",
"reporttime": "2023-04-18 23:08:57",
"casts": [{
"date": "2023-04-18",
"week": "2",
"dayweather": "晴",
"nightweather": "晴",
"daytemp": "27",
"nighttemp": "9",
"daywind": "东南",
"nightwind": "东南",
"daypower": "≤3",
"nightpower": "≤3",
"daytemp_float": "27.0",
"nighttemp_float": "9.0"
}, {
"date": "2023-04-19",
"week": "3",
"dayweather": "多云",
"nightweather": "多云",
"daytemp": "27",
"nighttemp": "12",
"daywind": "南",
"nightwind": "南",
"daypower": "4",
"nightpower": "4",
"daytemp_float": "27.0",
"nighttemp_float": "12.0"
}, {
"date": "2023-04-20",
"week": "4",
"dayweather": "多云",
"nightweather": "多云",
"daytemp": "22",
"nighttemp": "12",
"daywind": "东北",
"nightwind": "东北",
"daypower": "4",
"nightpower": "4",
"daytemp_float": "22.0",
"nighttemp_float": "12.0"
}, {
"date": "2023-04-21",
"week": "5",
"dayweather": "多云",
"nightweather": "多云",
"daytemp": "17",
"nighttemp": "9",
"daywind": "西南",
"nightwind": "西南",
"daypower": "≤3",
"nightpower": "≤3",
"daytemp_float": "17.0",
"nighttemp_float": "9.0"
}]
}]
}
然后用字典键值对查询指令，获取我们想要的信息，如：
s_city = data["forecasts"][0]["city"]
s_date = data["forecasts"][0]["casts"][0]["date"]
s_dayweather = data["forecasts"][0]["casts"][0]["dayweather"]
s_daytemp = data["forecasts"][0]["casts"][0]["daytemp"]
print(f"城市: {s_city}")
print(f"日期: {s_date}")
print(f"白天天气: {s_dayweather}")
print(f"白天温度: {s_daytemp}")
返回：
城市: 北京市
日期: 2023-04-19
白天天气: 多云
白天温度: 27

import requests
API_KEY = "8f2292423c70b8b79e63af30cd84498a"
city = "110000"
#extensions = "all"
url = f"https://restapi.amap.com/v3/weather/weatherInfo?key={API_KEY}&city={city}&extensions=all&output=JSON"
response = requests.get(url)
data = response.json()
print(data)
s_city = data["forecasts"][0]["city"]
s_date = data["forecasts"][0]["casts"][0]["date"]
s_dayweather = data["forecasts"][0]["casts"][0]["dayweather"]
s_daytemp = data["forecasts"][0]["casts"][0]["daytemp"]
print(f"城市: {s_city}")
print(f"日期: {s_date}")
print(f"白天天气: {s_dayweather}")
print(f"白天温度: {s_daytemp}")
