import socket
mysock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
mysock.connect(('data.pr4e.org',80))
cmd='GET http://data.pr4e.org/romeo.txt HTTP/1.0\n\n'.encode()
mysock.send(cmd)
while True:
data=mysock.recv(512)
if len(data)<1:
break
print(data.decode('utf-8'),end="")
mysock.close这是py4e课程中的一个示例脚本。当我运行它时，我得到的只是一些胡言乱语和一些HTML内容。一开始，我没有得到所有这些信息的编码错误。再也不知道为什么了。
当我在WSL (windows子系统)上运行脚本时，它正确地运行并获取文件。
这是Windows中在VSCode上运行的脚本的输出：

</html>在WSL中，我运行python3.8。在Windows中，我使用python3.9，在Windows中使用pyenv安装了3.8，但仍然没有。
我猜这跟编码和解码有关，但我不知道是怎么回事。
我还尝试在encode方法中设置utf-8，但是它没有改变任何事情。

您需要遵循HTTP协议，并使用\r\n作为行尾。
import socket
mysock=socket.socket()
mysock.connect(('data.pr4e.org', 80))
with mysock:

mysock.sendall(cmd)
