urequests — Related functions of HTTP client

Before we used the socket library, this tool as a primer is still good, for understanding the basic concepts of some crawlers, its helpful to master it. After get started, we need to learn some more advanced content and tools to facilitate our crawling. Then this section briefly introduces the basic usage of urequests library.

Response class

requests example

import urequests
from mpython import *

#连接网络
my_wifi = wifi()
my_wifi.connectWiFi('', '')

# 访问ip地址 api
r = requests.get("http://ip-api.com/json/")
print(r)
print(r.content)  # 返回响应的内容

print(r.content)
print(r.json())  # 返回响应的json编码内容并转为dict类型

# It's mandatory to close response objects as soon as you finished
# working with them. On MicroPython platforms without full-fledged
# OS, not doing so may lead to resource leaks and malfunction.
r.close()
