python 处理python socket recv的输出

Handling output of python socket recv

提问by chrism1

Apologies for the noob Python question but I've been stuck on this for far too long.

对 noob Python 问题表示歉意，但我已经被困在这个问题上太久了。

I'm using python sockets to receive some data from a server. I do this:

我正在使用 python 套接字从服务器接收一些数据。我这样做：

data = self.socket.recv(4)
print "data is ", data
print "repr(data) is ", repr(data)

The output on the console is this:

控制台上的输出是这样的：

data is
repr(data) is '\x00\x00\x00\x01'

数据是
repr(data) 是 '\x00\x00\x00\x01'

I want to turn this string containing essentially a 4 byte number into an int - or actually what would be a long in C. How can I turn this data object into a numerical value that I can easily manage?

我想将这个基本上包含 4 字节数字的字符串转换为 int - 或者实际上是 C 中的 long。如何将此数据对象转换为我可以轻松管理的数值？

You probably want to use struct.

您可能想使用struct。

The code would look something like:

代码如下所示：

import struct

data = self.socket.recv(4)
print "data is ", data
print "repr(data) is ", repr(data)
myint = struct.unpack("!i", data)[0]
