我收到错误 Traceback（最近一次调用最后一次）：json.decoder.JSONDecodeError：期望值：第 1 行第 1 列（字符 0）

我的代码：```

HOST = '0.0.0.0'
PORT = 10001

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.bind((HOST, PORT))
    s.listen()
    conn, addr = s.accept()
    with conn:
        print('Connected by', addr)
        while True:
            dataByte = conn.recv(1024)
            if not dataByte: 
                print("Not data")
            myStr = dataByte.decode('utf-8').replace("'", '"')
        
            data = json.loads(myStr)
            s = json.dumps(data, indent=4, sort_keys=True)
            print(s)
```

您的字符串似乎包含损坏的 Unicode 转义。转义\u后面是编码代码点的四个\u000380字符，例如，被解析为\u0003(aka ascii Control-C) 后跟普通数字"80"。

无论如何，当我尝试重现您的问题时，我得到的错误与您不同：

json.decoder.JSONDecodeError：无效的控制字符：第 1 行第 25 列（字符 24）

由于不知道还会发生什么，请创建一个包含您尝试解析的响应数据的测试字符串并将其嵌入到您的 Python 代码中（编辑您的问题，不要尝试在评论中这样做）。

我们只需要包含数据字符串和json.loads()调用...以及错误消息的代码。然后我们也许能够看到你所看到的，并取得进展。
