Method, device and system for processing images in internet

Technical Field

The invention relates to the technical field of networks, in particular to a method, a device and a system for processing images in the internet.

Background

With the development of the internet, especially various electronic commerce websites, photo sharing websites and the like, the requirements on images are more and more. Various web sites need to be provided with different sizes for the same image, such as a photograph, due to different presentation requirements and bandwidth limitations. For example, in some shopping websites, when listing a product, a 80 × 80 photo is usually provided, if a customer wants to see a product carefully, a 200 × 200 pixel or more photo is generally provided, while in other businesses, a more standard photo may be provided, and some businesses may need to perform some processing on the photo, such as watermarking a company, marking a brand, and so on.

The existing solution is to zoom the photos into different specifications in advance for storage to meet different application requirements; or only one size of the photo is provided as an original picture, and the original picture is downloaded to the client by the client and is automatically compressed and adjusted according to the needs of the client.

In the process of implementing the invention, the inventor finds that: if images with various specifications are stored in advance, a large number of files need to be generated, and when a new size is needed by a service, hundreds of millions of files need to be processed once to generate the size, so that the method is very inflexible and low in efficiency; if only one size of original pictures is provided, the original pictures are required to have higher quality in order to ensure the usability of the original pictures, so that a user needs to occupy a large amount of bandwidth in the process of downloading the original pictures to a client, and for a webpage displaying a product, when a plurality of pictures are displayed on one page, the page is basically not opened, and the real-time performance is poor.

step 101: a Content Delivery Network (CDN) node receives a picture access request sent by a user.

The picture access request carries a main file name and an auxiliary file name of the picture. The main file name corresponds to an original picture stored in the image server, and the auxiliary file name indicates a requirement for the picture, for example, a requirement for a specification of the picture, or a special processing requirement for the picture, such as watermarking, and the like.

Preferably, before step 101, the method further comprises:

and guiding the picture access request to the optimal CDN node away from the user through the DNS of the user access network.

The guidance is performed by DNS resolution, for example, by setting a DNS, requests for accessing a certain domain name in beijing are uniformly resolved to an IP address where a CDN site in beijing is located. This is the practice of standard internet DNS resolution. The CDN node which is optimal from the user is manually bound according to the network quality and the flow analysis of each region. For example, users in Beijing and Hebei can be directed to nodes in Beijing in a unified way.

The CDN is widely used for caching the image data near a user end, so that the access speed of the user is effectively improved, the data flow is dispersed, and the pressure of an image server is shunted.

Step 102: and when the CDN node does not have the pictures required by the picture access request, forwarding the picture access request to the image real-time processor.

Step 103: and the image real-time processor acquires an original image from the image storage center according to the image access request and processes the original image.

Step 104: and the image real-time processor returns the processed picture to the CDN node, and the CDN node provides the picture for the user to use.

In the embodiment of the invention, only one original picture is stored in the image server, and other pictures with various sizes can be calculated in real time by calling an image processing algorithm through the image real-time processor according to the parameters of the access request, so that the number of pictures to be stored is greatly reduced, and the flexibility of providing pictures with various requirements is greatly improved.

By the method provided by the embodiment of the invention, the original picture can be processed in real time according to the actual needs of the user, so that the user can obtain the needed picture.

Preferably, after step 104, further comprising:

step 105: and the CDN node stores the received picture.

The CDN stores the received picture, and can directly send the picture to the user without requesting the image real-time processor if the user requests the picture next time, so that time and network resources are saved, and efficiency is further improved.

Preferably, in another embodiment of the present invention, the step 102 of forwarding the picture access request to the image real-time processor specifically includes:

and the CDN node forwards the picture access request to an image real-time processor through an image server.

The method for forwarding the picture access request to the image real-time processor by the CDN node through the image server specifically includes:

the CDN node forwards the picture access request to an image server;

when the picture access request requires an original picture, the image server directly returns the original picture to the CDN node; otherwise, the picture access request is forwarded to the image real-time processor.

In the embodiment, before the CDN forwards the picture access request to the image real-time processor, the picture access request is forwarded to the image server, the image server determines whether the picture access request accesses an original picture, and if so, the original picture can be directly returned, and if not, the picture access request is forwarded to the image real-time processor for processing, so that the workflow of the image real-time processor is effectively saved, and the overall work efficiency is improved.

In addition, because pictures with various specifications can be obtained in real time by calling an image algorithm by the image real-time processor, a large amount of permanent storage space is saved.

Second, the embodiment of the present invention further describes a method for processing images in the internet, referring to fig. 2, where the method includes:

step 201: the CDN node receives a picture access request sent by a user.

Step 202: the CDN inquires whether a picture corresponding to the picture access request exists according to the picture access request, and if so, the step 203 is carried out; if step 204 is not entered.

Step 203: and returning the picture corresponding to the picture access request.

Step 204: and forwarding the picture access request to an image real-time processor.

Step 205: the image real-time processor judges whether the image required to be accessed is an original image or not according to the image access request, and if so, the step 206 is carried out; if not, go to step 207.

Step 206: and the image server issues the original picture.

Step 207: and the image real-time processor processes the original image according to the image access request and returns the processed image.

Preferably, step 207 further comprises:

and the image real-time processor normalizes the original images and unifies the original images into a format which can be identified by a browser.

By normalizing the original picture, uploading of some malicious codes disguised as the picture can be effectively prevented.
