Python No JSON object could be decoded

pythonjson

提问by Mario

I am having an issue with JSON, I can't seem to figure out why this is not working. This is supposed to output JSON.

我遇到了 JSON 问题,我似乎无法弄清楚为什么这不起作用。这应该输出JSON。

Here is my code

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');

I am getting this error

我收到此错误

Traceback (most recent call last):
  File "main.py", line 46, in 
    get_info('162.213.43.124');
  File "main.py", line 45, in get_info
    return json.loads(d.decode('utf8'))
  File "/usr/local/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/local/lib/python2.7/json/decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/local/lib/python2.7/json/decoder.py", line 383, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

If anyone could come to the rescue that would be awesome!

如果有人能来救援,那就太棒了!

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

您的 JSON 似乎无效。在这种情况下,这完全取决于服务器发送给您但您没有显示的数据。我建议通过JSON 验证器运行响应。
