如何从指向字符串的PyObject获取char * [英] How to get a char* from a PyObject which points to a string

问题描述

如何从指向字符串的 PyObject 中获取 char * .例如，这是python脚本

How can I get a char* from a PyObject which points to a string. For example, this is the python script,

Test.Connect("272.22.20.65", 1234)

这是C ++代码，

static PyObject* Connect(PyObject *self, PyObject *args)
{
    PyObject* pIP;
    PyObject* pPort;

    if (!PyArg_UnpackTuple(args, "Connect", 2, 2, &pIP, &pPort)) 
    {
        return NULL;
    }

    const char* zIP = GetAsString(pIP);
    long iPort      = PyLong_AsLong(pPort);

我想获取该IP地址为char *(GetAsString是伪函数:D).请注意，我正在使用Python 3.1.

I want to get that IP address as a char* (GetAsString is a dummy function :D ). Please note that I'm using Python 3.1.

P.S. 我认为此问题没有找到正确的答案， 因为在Python 3中没有 PyStringObject 或 PyString_AsString ，不是吗?

P.S. I don't think this question got the correct answer , since there is no PyStringObject or PyString_AsString in Python 3. Isn't it ?

推荐答案

首先，您获取它 .不要忘了临时引用.

First you encode it, then you retrieve it. Don't forget to decref the temporary.
