http - client 例程#
本示例程序用于对 CanMV 开发板进行一个 http client的功能展示。
import socket
def main(use_stream=True):
#创建socket
s = socket.socket()
#获取地址及端口号 对应地址
ai = socket.getaddrinfo("www.baidu.com", 80)
#ai = socket.getaddrinfo("10.100.228.5", 8080)
print("Address infos:", ai)
addr = ai[0][-1]
print("Connect address:", addr)
#连接
s.connect(addr)
if use_stream:
# MicroPython socket objects support stream (aka file) interface
# directly, but the line below is needed for CPython.
s = s.makefile("rwb", 0)
#发送http请求
s.write(b"GET /index.html HTTP/1.0\r\n\r\n")
#打印请求内容
print(s.read())
else:
#发送http请求
s.send(b"GET /index.html HTTP/1.0\r\n\r\n")
#打印请求内容
print(s.recv(4096))
#print(s.read())
#关闭socket
s.close()
#main()
main(use_stream=True)
main(use_stream=False)
