Python如何发送get请求

方式一：get请求，无参数

import requests

url = 'https://www.baidu.com/'
ret = requests.get(url)
print(ret)
print(ret.text)
# 如果返回的数据不是json格式，打印json格式会报错
# print(ret.json())

方式二：get请求，有参数

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请求，有多个参数

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请求，既有请求头，也有参数。

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())
