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), comprising:

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

converting, by the cache plugin, the key information and the operation type into a parameter required by a cloud cache operation and a cloud cache operation type, and transmitting, by the cache plugin, 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; and

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

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

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

converting, by the cache plugin, 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, further comprising after converting, by the cache plugin, the operation type into the cloud cache operation type:

establishing, by the cache plugin, one named pipe according to the cloud cache operation type; and

regularly detecting, by the cache plugin, 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, wherein returning, by the cloud cache apparatus, the cloud cache operation result by the cloud cache apparatus further comprises:

detecting, by the cloud cache apparatus, whether the named pipe exists; and

if the named pipe exists, writing, by the cloud cache apparatus, data into the named pipe.

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

judging, by the cache plugin, whether the key information is correct or whether the operation type is enabled; and

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

6. A system for realizing a Representational State Transfer (REST) interface of a cloud cache in an Engine x (Nginx) comprising 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 processor, a memory, and one or more program modules stored in the memory, the one or more program modules comprising:

a parsing module, stored in the memory, which, when executed, causes the processor 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, stored in the memory, which, when executed, causes the processor 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, stored in the memory, which, when executed, causes the processor 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, wherein the conversion module comprises:

a packaging unit, stored in the memory, which, when executed, causes the processor 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, stored in the memory, which, when executed, causes the processor 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, wherein the one or more program modules further comprise:

an establishment module, stored in the memory, which, when executed, causes the processor to establish one named pipe according to the cloud cache operation type;

a reading module, stored in the memory, which, when executed, causes the processor 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, wherein the cloud cache apparatus comprises another memory and another processor, and wherein the cloud cache apparatus further comprises:

a detection module, stored in the another memory, which, when executed, causes the another processor to detect whether the named pipe exists;

a writing module, stored in the another memory, which, when executed, causes the another processor to write data into the named pipe if the named pipe exists.

10. The system according to claim 6, wherein the one or more program modules further comprise:

a judgment module, stored in the memory, which, when executed, causes the processor 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.
