Python如何發送get請求

方式一：get請求，無參數

import requests

url = 'https://www.baidu.com/'
ret = requests.get(url)
print(ret)
print(ret.text)
# 如果返回的數據不是json格式，打印json格式會報錯
# print(ret.json())

方式二：get請求，有參數

import requests

url = 'http://web.juhe.cn:8080/environment/air/airCities'
parms01 = {
    'key':'6283b38527158b4085842f7354axxxxx'
}
ret = requests.get(url,params=parms01)
print(ret)
print(ret.text)
print(ret.json())

方式三：get請求，有多個參數

import requests

url = 'http://web.juhe.cn:8080/environment/air/pm'
parms02 = {
    'city':'shanghai',
    'key':'6283b38527158b4085842f7354xxxxxx'
}
ret = requests.get(url,params=parms02)
print(ret.json())

 方式四：get請求，既有請求頭，也有參數。

import requests

url = 'http://web.juhe.cn:8080/environment/air/pm'
parms02 = {
    'city':'shanghai',
    'key':'6283b38527158b4085842f7354xxxxxx'
}
headers = {
    'User-Agent':'PostmanRuntime/7.26.8',
    'Content-Type':'application/json'
}
ret = requests.get(url,params=parms02,headers=headers)
print(ret.json())
