How to use the interface in https://doc.owncloud.org/api

I find the interface in https://doc.owncloud.org/api/classes/OCP.IUserManager.html,but what it provides is the function not like the administrator documentation it provides the url like : http://admin:secret@example.com/ocs/v1.php/cloud/users?search=Frank , so anyone who can tell me how to use the interface in the https://doc.owncloud.org/api/classes/OCP.IUserManager.html

Hi

Attention: the api is a docu of all classes abailable in OC code.
It is not the api/url interface what you are trying to use

ok, i know ,but I just want to develop an destop app,and now I want to verify whether the uid match the password to achieve the functio of login ! I want to know whether there is such url I can use directly! so could you please help me solve the question and give me a hand!
