无法使用Poco获取字符串的路径

Question

I'm trying to put the path in a string, but it always empty:

Poco::URI uri("http://10.10.10.10:3535");
std::string path(uri.getPathAndQuery());

This string part never receive anything and stays empty.. The code snippet is taking from an example https://gist.github.com/FatalCatharsis/749d93b4592e7d59d91a

Answer 1

In your URI the Path and Query are empty, so it is correct that you see an empty string. Your URI only has a Scheme, Host and Port.

Here is a diagram of the URI format from Wikipedia:

                    authority               path
        ┌───────────────┴───────────────┐┌───┴────┐
  abc://username:password@example.com:123/path/data?key=value#fragid1
  └┬┘   └───────┬───────┘ └────┬────┘ └┬┘           └───┬───┘ └──┬──┘
scheme  user information     host     port            query   fragment

Answer 2

http://10.10.10.10:3535 does not have any path or query in the string, that is why it is empty. Here is you can separate URI :

scheme:[//[user:password@]host[:port]][/]path[?query][#fragment]
eg. http:://192.168.11.2:3000/user?action=edit#basic
