# Very simple HTTPS client example: # - Connects to a server. # - Upgrades the connection to a TLS connection. # - Sends a HTTP request. # - Reads the result. # # This example works in both MicroPython and CPython. # # To implement an HTTPS client using less code, use mip to install the requests package: # https://github.com/micropython/micropython-lib/tree/master/python-ecosys/requests import socket import ssl # `addr_family` selects IPv4 vs IPv6: 0 means either, or use # socket.AF_INET or socket.AF_INET6 to select a particular one. def main(domain, addr_family=0, use_stream=True): # Lookup the server address, for the given family and socket type. ai = socket.getaddrinfo(domain, 443, addr_family, socket.SOCK_STREAM) print("Address infos:", ai) # Select the first address. ai = ai[0] # Create a socket with the server's family, type and proto. s = socket.socket(ai[0], ai[1], ai[2]) # Connect to the server. addr = ai[-1] print("Connect address:", addr) s.connect(addr) # Upgrade the socket to a TLS connection. s = ssl.wrap_socket(s) print(s) # Send request and read response. if use_stream: # Both CPython and MicroPython SSLSocket objects support read() and # write() methods. s.write(b"GET / HTTP/1.0\r\n\r\n") print(s.read(4096)) else: # MicroPython SSLSocket objects implement only stream interface, not # socket interface s.send(b"GET / HTTP/1.0\r\n\r\n") print(s.recv(4096)) # Close the socket. s.close() main("google.com")
