Question

python recv函数会一直等待吗

Answer 1

d = s.recv(1024)
这段代码的返回值通过使用 not d 判断总是失败，于是那个循环读取的 while 就陷入了死循环，请各位帮忙看一下，谢谢！

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("www.oschina.net", 80))
s.send("GET / HTTP/1.1\r\nHost:www.oschina.net\r\n\r\n")

tmp = []
while True:
d = s.recv(1024)
if not d:
break
tmp.append(d)

data = ''.join(tmp)
s.close()

header, html = data.split("\r\n\r\n", 1)
print header
with open("oschina.html", "wb") as f:
f.write(html)
