Abstract

The present invention provides a method for realizing a REST (Representational State Transfer) interface of a cloud cache in an Nginx. The method includes: receiving a Hyper Text Transport Protocol (HTTP) message transmitted from a client, and parsing out key information and an operation type corresponding to the HTTP message according to a preset configuration file; converting the key information and the operation type into a parameter required by a cloud cache operation and a cloud cache operation type, and transmitting the parameter to a cloud cache apparatus, so that the cloud cache apparatus performs the cloud cache operation according to the parameter and the cloud cache operation type; receiving a cloud cache operation result returned by the cloud cache apparatus, processing the cloud cache operation result, and returning the processed result to the client. The present invention also provides a corresponding system. The present invention enables a larger cache capacity and better saves CPU resources, thereby enabling a more powerful cache function of the Nginx.

Claims

1. A method for realizing a Representational State Transfer (REST) interface of a cloud cache in an Engine x (Nginx), characterized in that the method comprises:

receiving a Hyper Text Transport Protocol (HTTP) message transmitted from a client, and parsing out key information and an operation type corresponding to the HTTP message according to a preset configuration file;

converting the key information and the operation type into a parameter required by a cloud cache operation and a cloud cache operation type, and transmitting the parameter to a cloud cache apparatus, so that the cloud cache apparatus performs the cloud cache operation according to the parameter and the cloud cache operation type;

receiving a cloud cache operation result returned by the cloud cache apparatus, processing the cloud cache operation result, and returning the processed result to the client.

2. The method according to claim 1, characterized in that converting the key information and the operation type into the parameter required by the cloud cache operation and the cloud cache operation type, and transmitting the parameter to the cloud cache apparatus comprises:

packaging the key information corresponding to the HTTP message as a Key-Value packet required by the cloud cache operation, and transmitting the Key-Value packet to the cloud cache apparatus for processing; and

converting the operation type into the cloud cache operation type, so that the cloud cache apparatus operates according to the cloud cache operation type.

3. The method according to claim 2, characterized in that after converting the operation type into the cloud cache operation type, the method further comprises:

establishing one named pipe according to the cloud cache operation type;

regularly detecting whether there are data returned from the cloud cache apparatus existing in the named pipe;

if there are data returned from the cloud cache apparatus existing in the named pipe, reading out the data in the pipe file.

4. The method according to claim 3, characterized in that returning the cloud cache operation result by the cloud cache apparatus comprises:

detecting whether the named pipe exists;

if the named pipe exists, writing data into the named pipe.

5. The method according to claim 1, characterized in that before converting the key information and the operation type into the parameter required by the cloud cache operation and the cloud cache operation type, the method further comprises:

judging whether the key information is correct or whether the operation type is enabled;

if the key information is not correct or the operation type is not enabled, ending the process.

6. A system for realizing a Representational State Transfer (REST) interface of a cloud cache in an Engine x (Nginx), characterized in that the system comprises:

a cache plugin and a cloud cache apparatus, wherein the cloud cache apparatus is configured to perform a cloud cache operation, and the cache plugin comprises;

a parsing module, which is configured to receive a Hyper Text Transport Protocol (HTTP) message transmitted from a client, and parse out key information and an operation type corresponding to the HTTP message according to a preset configuration file;

a conversion module, which is configured to convert the key information and the operation type into a parameter required by a cloud cache operation and a cloud cache operation type, and transmit the parameter to the cloud cache apparatus, so that the cloud cache apparatus performs the cloud cache operation according to the parameter and the cloud cache operation type; and

a return module, which is configured to receive a cloud cache operation result returned by the cloud cache apparatus, process the cloud cache operation result, and return the processed result to the client.

7. The system according to claim 6, characterized in that the conversion module comprises:

a packaging unit, which is configured to package the key information corresponding to the HTTP message as a Key-Value packet required by the cloud cache operation, and transmit the Key-Value packet to the cloud cache apparatus for processing; and

a conversion unit, which is configured to convert the operation type into the cloud cache operation type, so that the cloud cache apparatus operates according to the cloud cache operation type.

8. The system according to claim 7, characterized in that the cache plugin further comprises:

an establishment module, which is configured to establish one named pipe according to the cloud cache operation type;

a reading module, which is configured to regularly detect whether there are data returned from the cloud cache apparatus existing in the named pipe, and read out the data in the pipe file if there are data returned from the cloud cache apparatus existing in the named pipe.

9. The system according to claim 8, characterized in that the cloud cache apparatus comprises:

a detection module, which is configured to detect whether the named pipe exists;

a writing module, which is configured to write data into the named pipe if the named pipe exists.

10. The system according to claim 6, characterized in that the cache plugin further comprises:

a judgment module, which is configured to judge whether the key information is correct or whether the operation type is enabled, and end the process if the key information is not correct or the operation type is not enabled.
