我遇到了JSON的问题,我似乎无法弄清楚为什么这不起作用。这应该输出JSON。
这是我的代码
#!/usr/bin/env python
import socket
import struct
import json
def unpack_varint(s):
d = 0
i = 0
while True:
b = ord(s.recv(1))
d |= (b & 0x7F) << 7*i
i += 1
if not b & 0x80:
return d
def pack_data(d):
return struct.pack('>b', len(d)) + d
def pack_port(i):
return struct.pack('>H', i)
def get_info(host, port=25565):
# Connect
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
# Send handshake + status request
s.send(pack_data("\x00\x00" + pack_data(host.encode('utf8')) + pack_port(port) + "\x01"))
s.send(pack_data("\x00"))
# Read response
unpack_varint(s) # Packet length
unpack_varint(s) # Packet ID
l = unpack_varint(s) # String length
d = ""
while len(d) < l:
d += s.recv(1024)
# Close our socket
s.close()
# Load json and return
return json.loads(d.decode('utf8'))
get_info('162.213.43.124');
我收到此错误
Traceback (most recent call last):

如果有人能来救援那真棒!
