Question

我遇到过python上的一些问题。我尝试用socket.recv(1024)读取发送的数据，但有时数据的长度超过1024字节。我试试这段代码：

data = b''
received = s.recv(1024)
    while len(received) > 0:
        data = data + received
        received = s.recv(1024)

但是while循环代码无穷大。我该如何解决？

以下是您可以如何处理此问题（未经测试）：

MINIMUM_PACKET_LENGTH = 100
data = b''
while True:
    try:
        received = s.recv(1024)
    except:
        # you might put code here to handle the exception,
        # but otherwise:
        raise
    data = data + received
    while len(data) >= MINIMUM_PACKET_LENGTH:
        # consume a packet from the data buffer, but leave unused bytes in data
        packet = data[0:MINIMUM_PACKET_LENGTH]
        data = data[MINIMUM_PACKET_LENGTH:]
        # process packet (you could maybe use 'yield packet')
        # ....

如何使用socket.recv（）获取完全发送的数据？
