microsoft cpprestsdk listen to multiple url with same ip? - cpprest-sdk

Question

I want to use cpprestsdk to make a restful API,
I copied some code from here :
int main()
{
http_listener listener("http://0.0.0.0:9080/demo/work1");
cout<<"start server!"<<endl;
listener.support(methods::GET, handle_get);
listener.support(methods::POST, handle_post);
listener.support(methods::PUT, handle_put);
listener.support(methods::DEL, handle_del);
try
{
listener
.open()
.then([&listener]() {TRACE(L"\nstarting to listen\n"); })
.wait();
while (true);
}
catch (exception const & e)
{
cout << e.what() << endl;
}
return 0;
}
now I have to listen to not only "http://0.0.0.0:9080/demo/work1" , but also "http://0.0.0.0:9080/demo/work2", "http://0.0.0.0:9080/realfunction/work1". All in the same IP and port, but different sub-path
Should I use multiple listener to handle all the url one by one in multi-thread? Or there is any other way to handle this?

You can set
http_listener listener("http://0.0.0.0:9080/");
And then in the handler check the request. In the examples linked in cpprestsdk's github I saw things like
void handle_get(http_request message) {
auto path = uri::split_path(uri::decode(message.relative_uri().path()));
if (path.size() == 2 && path[0] == "demo" && path[1] == "work1") {
// ...
} else if (path.size() == 2 && path[0] == "demo" && path[1] == "work2") {
// ...
} else {
message.reply(status_codes::NotFound);
}
}
