Abstract

A method includes: parsing a widget package that is to be run in a terminal to obtain component information in the widget package; obtaining registration information of a component in the widget package according to the component information; when the obtaining of the registration information fails, downloading a component according to component download request information sent by the terminal and updating the registration information; and invoking the downloaded component according to the updated registration information, so that a widget logic component may be updated separately, and a function of a widget terminal is implemented flexibly and easily.

Claims

1. A method for invoking a widget, comprising:

parsing a widget package that is to be run in a terminal to obtain component information in the widget package;

obtaining registration information of a component in the widget package according to the component information;

when the obtaining of the registration information fails, downloading a component according to component download request information from the terminal, and updating the registration information; and

invoking the downloaded component according to the updated registration information.

2. The method according to claim 1, wherein when the obtaining of the registration information succeeds, a component that corresponds to the successfully obtained registration information is invoked.

3. The method according to claim 1, wherein the obtaining the registration information of the component in the widget package according to the component information further comprises:

obtaining, by the terminal, according to the component information, the registration information of the component from a list that is obtained by an extension interface, wherein the list that is obtained by the extension interface is set in the terminal.

4. The method according to claim 1, wherein:

the registration information is used for identifying a component, and comprises one or multiple kinds of the following;

a component name, a component version, a component author, a description of a component function, a description of a dependency relationship between components, or a description of a component execution environment; and

the component download request information further comprises one or multiple kinds of the following information;

terminal hardware configuration information, terminal software configuration information, information about a downloaded component of the terminal, terminal state information, information about a user, or authentication information of the user.

5. The method according to claim 1, wherein the downloading the component according to the component download request information further comprises:

reporting, according to the component download request information, a policy to a component server that corresponds to the terminal, and collecting a component that is returned by the component server to the terminal according to the reported policy.

6. The method according to claim 1, wherein the invoking the downloaded component according to the updated registration information further comprises:

invoking an un-downloaded component through the downloaded component according to the updated registration information.

7. A terminal for invoking a widget, comprising:

a parsing unit, configured to parse a widget package that is to be run in a terminal to obtain component information in the widget package;

a component registering unit, configured to obtain registration information of a component in the widget package according to the component information; and

a component managing unit, configured to download, when the obtaining of the registration information fails, a component according to component download request information and update the registration information; and

invoke the downloaded component according to the updated registration information.

8. The terminal according to claim 7, wherein the component managing unit is further configured to invoke, when the obtaining of the registration information succeeds, a component that is corresponding to the successfully obtained registration information.

9. The terminal according to claim 7, wherein the component registering unit is further configured to:

obtain, according to the component information, the registration information of the component from a list that is obtained by an extension interface, wherein the list that is obtained by the extension interface is set in the component registering unit, and the registration information is used for identifying a component and comprises one or multiple kinds of the following;

a component name, a component version, a component author, a description of a component function, a description of a dependency relationship between components, or a description of a component execution environment.

10. The terminal according to claim 7, wherein the component download request information comprises:

terminal hardware configuration information, terminal software configuration information, information about a downloaded component of the terminal, terminal state information, information about a user, or authentication information of the user.

11. The terminal according to claim 7, wherein the component managing unit is further configured to report, according to the component download request information, policy information to a component server that is corresponding to the terminal, and collect a component that is returned by the component server to the component managing unit according to the policy information.

12. A method for invoking a widget, comprising the following steps:

receiving component download request information reported by a widget terminal;

delivering a request for device information to the widget terminal according to an internal policy; and

after receiving a device information list that is reported by the widget terminal after the widget terminal collects device information according to the request for device information, delivering a component for downloading to the widget terminal.

13. The method according to claim 12, wherein the internal policy comprises one or multiple kinds of the following:

terminal hardware configuration information, terminal software configuration information, terminal state information, user information, information about a downloaded component of the terminal, or a dependency relationship between components; and

according to different internal policies, different versions of the component are selected for delivery.

14. An apparatus for invoking a widget, comprising a policy managing module and a server component library, wherein:

the policy managing module is configured to deliver, after receiving component download request information reported by a widget terminal, a request for device information to the widget terminal according to an internal policy that is managed by the policy managing module; and

a server component library, configured to deliver a component for downloading to the widget terminal after receiving a device information list that is reported by the widget terminal after the widget terminal collects device information according to the request for device information, wherein the component for downloading is stored in the server component library.

15. The apparatus according to claim 14, wherein the internal policy comprises one or multiple kinds of the following:

terminal hardware configuration information, terminal software configuration information, terminal state information, user information, information about a downloaded component of the terminal, or a dependency relationship between components; and

according to different internal policies, different versions of the component are selected through the server component library for delivery.
