我想创建一个网络服务器，仅使用我的 raspberry pi pico w 提供基本的 index.html 文件。我可以在 micropython 中执行此操作，但我需要在该项目中使用 Circuitpython。我找到了一些代码来创建软访问点，但我无法使用该代码创建网络服务器。

我找到的代码：
# import wifi module
import wifi
# set access point credentials
ap_ssid = "myAP"
ap_password = "password123"
# You may also need to enable the wifi radio with wifi.radio.enabled(true)
# configure access point
wifi.radio.start_ap(ssid=ap_ssid, password=ap_password)
"""
start_ap arguments include: ssid, password, channel, authmode, and max_connections
"""
# print access point settings
print("Access point created with SSID: {}, password: {}".format(ap_ssid, ap_password))
# print IP address
print("My IP address is", wifi.radio.ipv4_address)
我尝试添加网络服务器的代码：
import wifi
import socketpool
# Set access point credentials
ap_ssid = "myAP"
ap_password = "password123"
# Configure access point
wifi.radio.start_ap(ssid=ap_ssid, password=ap_password)
# Print access point settings
print("Access point created with SSID: {}, password: {}".format(ap_ssid, ap_password))
print("My IP address is", wifi.radio.ipv4_address)
# Create a socket pool
pool = socketpool.SocketPool(wifi.radio)
# Create a simple HTTP server function
def simple_http_server():
server_socket = pool.socket()
server_socket.bind((wifi.radio.ipv4_address, 80))
server_socket.listen(1)
print("Server is listening on {}:80".format(wifi.radio.ipv4_address))
while True:
print("Waiting for a connection...")
client_socket, client_address = server_socket.accept()
print("Accepted connection from:", client_address)
client_socket.send("HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n")
client_socket.send("<html>Hello, World!</html>\r\n")
client_socket.close()
# Start the HTTP server
simple_http_server()
现在我得到的错误是：
Access point created with SSID: myAP, password: password123
My IP address is None
Traceback (most recent call last):
File "<stdin>", line 36, in <module>
File "<stdin>", line 21, in simple_http_server
TypeError: can't convert 'NoneType' object to str implicitly
我尝试使用 chatgpt 来帮助我解决这个问题，因为我不熟悉 CircuitPython，但即使他也无法弄清楚，它一直希望我使用 adafruit_requests 作为模块，但我没有该模块。
欢迎所有帮助。预先感谢！
发生这种情况的原因是因为
wifi.radio.ipv4_addresswifi.radio.ipv4_address_apipv4_address: ipaddress.IPv4Address
IP v4 连接到接入点时的站地址。否则没有。 （只读）ipv4_subnet_ap: ipaddress.IPv4Address
IPv4 接入点子网的地址（启用后）。否则没有。 （只读） https://docs. Circuitpython.org/en/latest/shared-bindings/wifi/index.html#wifi.Radio
这是更新后的代码：
import wifi
import socketpool
# Set access point credentials
ap_ssid = "myAP"
ap_password = "password123"
# Configure access point
wifi.radio.start_ap(ssid=ap_ssid, password=ap_password)
# Print access point settings
print("Access point created with SSID: {}, password: {}".format(ap_ssid, ap_password))
print("My IP address is", str(wifi.radio.ipv4_address_ap))
# Create a socket pool
pool = socketpool.SocketPool(wifi.radio)
# Create a simple HTTP server function
def simple_http_server():
server_socket = pool.socket()
server_socket.bind((str(wifi.radio.ipv4_address_ap), 80))
server_socket.listen(1)
print("Server is listening on {}:80".format(wifi.radio.ipv4_address))
while True:
print("Waiting for a connection...")
client_socket, client_address = server_socket.accept()
print("Accepted connection from:", client_address)
client_socket.send("HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n")
client_socket.send("<html>Hello, World!</html>\r\n")
client_socket.close()
# Start the HTTP server
simple_http_server()
注意： 确保在使用之前将
