boost asio iostream - 如何获取本地IP地址 [英] boost asio iostream - how to get local IP address
问题描述
这是我的问题:
我正在使用boost :: asio :: ip :: tcp :: iostream连接到服务器:
Here is my problem: I'm using boost::asio::ip::tcp::iostream to connect to server:
boost::asio::ip::tcp::iostream s(IP, "1237");
现在我想检索自己的本地IP地址。我已经在谷歌的深处发现了如何使用 socket ,但是一个流呢?
我希望由于tcp :: iostream构建在套接字的顶部,它应该是这样的:
s.local_endpoint()。address()
但是经过长时间的谷歌搜索和duckduckgo我没有发现如何做到这一点。我尝试了几种最明显的排列,但仍然没有运气。
那么,有没有简单的方法,或者我必须使用套接字?
如果它很重要,它只需要在Linux上运行。
And now I want to retrieve my own, local IP address. I have found somewhere in the depths of google how to do it with a socket, but what about a stream? I expect that since tcp::iostream is built on the top of a socket it should be something like: s.local_endpoint().address() but after a long search with google and duckduckgo I have found no clue how to do it. I have tried several most obvious permutations, but still no luck. So, is there any simple way to do it, or do I have to use socket? It only has to work on Linux, if it is important.
推荐答案
假设Linux,请使用 getifaddrs(3)
获取本地系统的接口列表。
Assuming Linux, Use getifaddrs(3)
to get a list of interfaces for the local system.
