sending an external-link creation success response to the second client, wherein the external-link creation success response carries the identifier of the external link.

8. A method for acquiring a resource comprising:

acquiring, by a first client, resource information of a resource to be uploaded; and

sending, by the first client, a resource check request to a storage server, wherein the resource check request carries the resource information, an identifier of an external link created by a second client, and storage location information corresponding to the external link, so that the storage server searches, according to the identifier of the external link, a database configured to store external-link information for an attribute of the external link corresponding to the identifier of the external link, checks the resource information according to a value of the found attribute, and stores the acquired resource according to the storage location information after the check succeeds.

9. The method according to claim 8, wherein acquiring, by the first client, the resource information of the resource to be uploaded comprises:

logging, by the first client, into the storage server;

receiving, by the first client, a resource information list sent by the storage server, wherein the resource information list comprises resource information of resources stored at the server by the first client; and

acquiring, by the first client, resource information selected by a public visitor from the resource information list.

10. The method according to claim 8, wherein, after the storage server successfully performs the check, the method further comprises:

receiving, by the first client, a resource check success response sent by the storage server; and

sending, by the first client, the resource to the storage server.

11. A storage server comprising:

a receiving unit configured to receive a resource check request sent by a first client, wherein the resource check request carries resource information of a resource to be uploaded by the first client, an identifier of an external link created by a second client, and storage location information corresponding to the external link;

a searching unit configured to search, according to the identifier of the external link received by the receiving unit, a database configured to store external-link information for an attribute of the external link corresponding to the identifier of the external link;

a checking unit configured to check, according to a value of the attribute found by the searching unit, the resource information received by the receiving unit; and

a storing unit configured to store the acquired resource or acquired resource location information according to the storage location information received by the receiving unit after the checking unit successfully performs the check.

12. The storage server according to claim 11 further comprising an acquiring unit configured to:
