A digital certificate obtaining method and apparatus. The method includes: a routing device receives a network access request sent by a terminal on the basis of a first virtual local area network, wherein the first virtual local area network is associated with a uniform resource locator (URL) of a server, so that the terminal obtains, by means of the server, a digital certificate used for accessing a second virtual local area network; and in response to the network access request sent by the terminal on the basis of the first virtual local area network, the routing device sends the URL of the server to the terminal, so that the terminal obtains the digital certificate from the server according to the URL.
