MongoCXX 3.4 - Using a unix domain socket URI

Question

I am trying to connect to MongoDB via the c++ driver. If I provide the IP based URI everything works fine, however when I try to use a unix domain socket URI I get the following error:

an invalid MongoDB URI was provided

I am trying to connect in the following way:

mongocxx::uri uri{"mongodb:///tmp/mongodb-27017.sock"};                                  
mongocxx::pool *p = new mongocxx::pool (uri); 

If I replace the uri string with mongodb://localhost:27017/?minPoolSize=0&maxPoolSize=10 , it works just fine.

I am probably doing something wrong, not sure what though.

Answer 1

You need to add a trailing / . Try mongocxx::uri uri{"mongodb:///tmp/mongodb-27017.sock/"}; .
