Implementing method of technology for logging in a number of different systems from same one client

The invention provides an implementing method of a technology for logging in a number of different systems from same one client. The method comprises the steps of: step 1, building an interlayer system and storing a mapping table of an account number and a system access path in the interlayer system; step 2, firstly visiting the interlayer when the account is added in each system to judge whetherthe mapping relation of the account exists in the interlayer or not; if so, stopping adding the account; if not, adding the account and adding the mapping relation of the account name and the currentsystem access path in the mapping table of the interlayer; and step 3, firstly visiting the interlayer when a user is logging in the client; judging whether the mapping relation of the account existsin the interlayer or not; if so, acquiring the corresponding system access path according to the account name and using the access path to log in the corresponding system; and if not, prompting the user that the account does no
