Find multiple users, by their usernames
This method works like the services/users/by_username method, but works with multiple users (instead of only one).
Pipe-separated list of usernames. No more than 500 are allowed.
Same as in the services/users/user method. Pipe-separated list of field names which you are interested with. See services/users/user method for a list available values.
|format||optional||Standard common formatting argument.|
|callback||optional||Standard common formatting argument.|
|Plus required consumer_key argument, assigned for your application.|
A dictionary. Usernames you provide will be mapped to dictionary keys, and each value will be a dictionary of fields you have selected.
Value of null means that the given user haven't been found. (This behavior is different than in the services/users/by_username method, which responds with an HTTP 400 error in such case.)
