requests简单应用

• requests发送get请求

1. 无参数的get请求:

response = requests.get(url='http://ws.webxml.com.cn/WebServices/WeatherWS.asmx/getRegionProvince')
s = response.status_code

2.有参数的get请求

url = 'http://ws.webxml.com.cn/WebServices//WeatherWS.asmx/getSupportCityString'
params= {'theRegionCode':3113}
response = requests.get(url = url,params=params)

• requests发送post请求

"""
post请求常见的四种方式
    1.application/x-www-form-urlencoded :最常见的post提交数据的方式,浏览器的原生<form>表单
    2.form-data :一般用来上传文件
    3.application/json :作为请求头,用来告诉服务端消息主体是序列化的JSON字符串
    4.text/xml
