# 简单的HTTPS客户端示例。

import network

# AP info
SSID = ""  # Network SSID
KEY = ""  # Network key

PORT = 80
HOST = "www.google.com"

# 初始化wlan模块并连接到网络
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(SSID, KEY)

while not wlan.isconnected():
    print('Trying to connect to "{:s}"...'.format(SSID))
    time.sleep_ms(1000)

# 我们现在应该有一个通过DHCP的有效IP了
print("WiFi Connected ", wlan.ifconfig())

# 通过DNS获取addr信息
addr = socket.getaddrinfo(HOST, PORT)[0][4]
print(addr)

# 创建一个新的套接字并连接到addr
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect(addr)

# 设置超时
client.settimeout(3.0)

# 发送HTTP请求和recv响应
client.send("GET / HTTP/1.1\r\nHost: %s\r\n\r\n" % (HOST))
print(client.recv(1024))

# 关闭套接字
client.close()
