Fig. 1 is a schematic diagram of an implementation environment of a picture issuing method provided in an embodiment of the present application, and as shown in fig. 1, the implementation environment includes: a terminal 101 and a server 102.
The server 102 is a server for providing a picture to be previewed for the terminal 101, and when a page display component of the terminal 101 needs to display the picture, the terminal 101 sends a picture issuing request to the server 102, where the picture issuing request includes a picture size required by the page display component. Optionally, the server 102 belongs to a Content Delivery Network (CDN), and caches Content required by the terminal 101, including pictures corresponding to picture sizes required by page display components of different terminals, so as to provide a quick access response for the terminal 101. In this way, the server 102 issues the target picture corresponding to the required picture size according to the received picture issuing request, so that the CDN hit rate is maximally ensured while the picture definition is ensured. The CDN hit rate refers to a probability that the cache content of the server 102 is hit by the access request of the terminal 101.
In one possible implementation manner, the terminal 101 may be any electronic product capable of performing human-Computer interaction with a user through one or more manners of a keyboard, a touch pad, a touch screen, a remote controller, voice interaction, or a handwriting device, for example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a pocket PC (pocket PC), a tablet Computer, a smart car machine, a smart television, a smart sound box, and the like. The server 102 may be any one of a server, a server cluster composed of several servers, a virtual cloud storage, or a cloud computing center. The server 102 is used for providing background services for the terminal 101, and the server 102 has a data storage capability and can store related data for picture display. The server may be one server, a server cluster composed of a plurality of servers, or a cloud computing service center. The terminal 101 and the server 102 establish a communication connection through a wired or wireless network.
The terminal 101 may be generally referred to as one of a plurality of terminals, and the embodiment is only illustrated by the terminal 101. Those skilled in the art will appreciate that the number of terminals 101 described above may be greater or fewer. For example, the number of the terminal 101 may be only one, or the number of the terminal 101 may be several tens or several hundreds, or more, and the number of the terminals and the device types are not limited in the embodiment of the present application.
Those skilled in the art will appreciate that the terminal 101 and the server 102 are only examples, and other existing or future terminals or servers may be suitable for the application, and are included within the scope of the present application and are incorporated by reference herein.
Based on the foregoing implementation environment, the embodiment of the present application provides a picture delivery method, which may be interactively executed by the terminal 101 and the server 102 in fig. 1, taking a flowchart of the picture delivery method provided in the embodiment of the present application shown in fig. 2 as an example. As shown in fig. 2, the method includes the following steps 201 to 205.
Step 201, the terminal generates a target picture issuing request based on the page picture assembly and the screen resolution.
In this embodiment of the present application, the target picture issuing request includes a target picture identifier and a target picture size, and the target picture size includes at least one of a picture height and a picture width. Illustratively, the picture height and the picture width are the number of pixels occupied by the picture in the height direction and the number of pixels occupied by the picture in the width direction, the unit of the picture height and the picture width is a pixel unit (px), the pixel unit is a relative unit, and the size of the pixel unit is different under different terminal devices.
In a possible implementation manner, the picture issuing request further carries information such as a picture watermark and a picture compression parameter, and is used for processing a target picture of the request according to a user requirement, so that the picture meeting the user requirement is displayed. The picture watermark refers to a semi-transparent mark (logo), an icon, a character copyright or a website, and the like which are added on the picture and prevent others from stealing the picture; the picture compression parameters refer to parameter values for performing compression operation on pictures so as to obtain compressed pictures meeting user requirements.
In a possible implementation manner, the page of the terminal includes a plurality of page picture assemblies, and one page picture assembly is used for displaying one picture and has a required target picture size. That is, the page picture assembly is used to control the page display picture of the terminal, and the size of the target picture size is determined by the picture size required by the page picture assembly. Therefore, the picture issuing request sent by the terminal is a picture issuing request corresponding to any page picture component in the current page, which is not limited in the embodiment of the present application. The number of page image components included in a page is at least one, and in the embodiment of the present application, the description of image delivery is performed only by taking the number of page image components in the page as an example, and when the number of page image components in the page is multiple, a processing procedure of each page image component is consistent with a process of image delivery in which the number of page image components is one, and details are not repeated here.
In a possible implementation manner, referring to fig. 3, the terminal generates a target picture issuing request based on the page picture assembly and the screen resolution, including the following steps 2011 to 2014.
In step 2011, the parameters of the page image assembly and the screen resolution of the terminal are obtained.
In one possible implementation, the page picture component parameters include a page picture identifier, a number of page pictures, and a total amount of page whiteout. The page picture identifier is used for indicating the identifier of the requested picture, namely identifying a certain picture of the request; the number of the page pictures is the number of pictures which can be displayed on the current page, for example, for a page with double-row display pictures, the number of the page pictures in the page transverse direction is 2; the total page whiteout amount is the remaining whiteout amount of the current page except for the displayed picture, for example, for a page with a single-column displayed picture, the whiteout amount of 10 device independent pixels (dp) is respectively arranged at the left and the back sides of the displayed picture position of the page picture component, and then the total page whiteout amount is 20 dp. Where dp is a unit of length, a unit independent of px, scaled by px equal to the product of dp and pixel ratio. Since screen resolutions of different terminal devices are different, pixel ratios are different, and conversion relations between px and dp are different, the unit of the page blank amount is not limited in the embodiment of the present application.
In a possible implementation manner, acquiring a target picture identifier and a required picture size corresponding to a page picture assembly according to a page picture assembly parameter and a screen resolution includes: acquiring a target picture identifier based on the page picture identifier; and performing difference operation on the screen resolution and the page margin total amount, and determining the required picture size corresponding to the page picture component according to the difference operation result and the page picture number. The determined required picture size may include a picture height and a picture width, may include only the picture height, or may include only the picture width.
In a possible implementation manner, the page display picture displays pictures in a fixed picture quantity manner, and the page picture component parameters of the page include a page picture identifier, a page picture quantity, and a page margin total quantity, where the page picture quantity includes a page horizontal picture quantity and a page vertical picture quantity, and the page margin total quantity includes a page horizontal margin total quantity and a page vertical margin total quantity. Performing difference operation on the height size of the screen resolution and the total longitudinal margin of the page, and taking the quotient of the difference operation result and the longitudinal picture number of the page as the picture height of the required picture size corresponding to the page picture component; and performing difference operation on the width size of the screen resolution and the total amount of the horizontal page margins, and taking the quotient of the difference operation result and the number of the horizontal page pictures as the picture width of the required picture size corresponding to the page picture component. Therefore, the required picture size corresponding to the page picture component is obtained, and the required picture size comprises the picture height and the picture width.
In a possible implementation manner, the page display picture is displayed in a wide adaptive manner, and the page picture component parameters of the page include a page picture identifier, a page picture number, and a page margin total amount, where the page picture number is a page vertical picture number, and the page margin total amount is a page vertical margin total amount. And performing difference operation on the height size of the screen resolution and the total vertical margin of the page, and taking the quotient of the difference operation result and the number of the vertical pictures of the page as the picture height of the required picture size corresponding to the page picture component. Therefore, the required picture size corresponding to the page picture component is obtained, and the required picture size only comprises the picture height at the moment.
In a possible implementation manner, the page display picture is displayed in a highly adaptive manner, and the page picture component parameters of the page include a page picture identifier, a page picture number, and a page margin total amount, where the page picture number is a page horizontal picture number, and the page margin total amount is a page horizontal margin total amount. And performing difference operation on the width size of the screen resolution and the total amount of the horizontal page margins, and taking the quotient of the difference operation result and the number of the horizontal page pictures as the picture width of the required picture size corresponding to the page picture component. Thus, the desired picture size of the page picture assembly corresponds to the desired picture size, which includes only the picture width.
Illustratively, taking a home page of an application as an example, a page image assembly of the home page is set to be a double-row image display form, the double-row image display form displays images in a longitudinal direction self-adaptive manner, the number of home page display columns is 2, the number of page images is 2, the left and right margins of a screen are 10dp respectively, and the middle margin is 5 dp. Then, for terminals with different screen resolutions, the widths of the pictures required by the home page are different, the left and right blank amounts and the middle blank amount of the screen are summed to obtain a total blank amount of 25dp, the value of the screen resolution of the mobile phone is subtracted from the value of the total blank amount, then the difference result and the value of the number of the pictures in the page are taken as a ratio, and the result of the ratio is the required picture width. When the screen resolution of the terminal is 1920 × 1080px, the conversion magnification of dp and px is 2, i.e., 1dp is 2px, and then the total amount of whiteout is 50px, resulting in a value of a required picture width of (1080-50)/2, i.e., 515 px. When the screen resolution of the device is 2208 × 1242px, the dp and px conversion magnification is 3, i.e., 1dp — 3px, and then the total amount of whitespace is 75px, resulting in a desired picture width of (1242-75)/2, i.e., 583 px.
In one possible implementation, before determining the target picture size in the page size set according to the required picture size, the method further includes: collecting required picture sizes corresponding to page picture assemblies of different terminals to generate a picture size sample set, wherein the picture size sample set comprises a plurality of picture sizes, and the values of the picture sizes are different; and clustering the picture size sample set, and obtaining a page size set according to a clustering result.
Due to the fact that the iterative updating speed of the terminal equipment is high, the models of the terminal equipment are more and more, the types of screen resolutions of the equipment are more and more, and according to statistics, the screen resolutions of 180 types are included at present. Meanwhile, the page types of the device display page also include many types, such as a home page, an evaluation list page, a merchant album page, a focus page, and the like. The page picture component types of different pages are different, such as single column display, double column display, left and right blank and middle blank. Therefore, different terminal devices have different picture sizes required by different page picture assemblies under different pages, the total number of the required different picture sizes is thousands of, and for a server, compared with caching pictures according to a fixed size, caching pictures according to the size required by the page picture assemblies can lead to the explosive increase of the picture amount cached by the server by thousands of times, so that the hit rate of the server is low, and the picture downloading delay is increased.
In one possible implementation, the above problem may be solved by a clustering algorithm that can process a large sample set into a representative small sample set. Illustratively, a k-means (k-means) clustering algorithm may be used, which is an iterative solved clustering analysis algorithm with a sample set as input, and the algorithm steps are: dividing the sample set into K (K is an integer not less than 1) groups in advance, randomly selecting K objects as initial clustering centers, then calculating the distance between each sample and each seed clustering center, and allocating each sample to the nearest clustering center. The cluster centers and the samples assigned to them represent a cluster. The cluster center of a cluster is recalculated for each sample assigned, based on the existing samples in the cluster. This process will be repeated until some termination condition is met. The termination condition may be that no (or a minimum number) of samples are reassigned to different clusters, no (or a minimum number) cluster centers are changed again, and the sum of squared errors is locally minimal. In the embodiment of the application, the sample sets can be clustered through a clustering algorithm, samples with similar characteristics are clustered into one class, and a small clustered sample set is obtained.
In a possible implementation manner, taking the album page as an example, for a terminal with a screen resolution of 1080px, the width of the picture size required by the page picture assembly includes: 480px, 481px, 482px, 483px, 485px, 486px, 487px, 485px, and 490px, etc. After the processing by the clustering method, the width of the picture size required by the page picture component can be gathered to be 500 px. In this way, the number of picture size sample sets is reduced, the server hit rate is increased, and the access delay is shortened. In addition, the dimension of the required picture size set is reduced through a clustering algorithm, the hit rate of the server cache pictures is improved to the maximum extent, and the downloading delay of the pictures is reduced.
In a possible implementation manner, the picture size set obtained by processing through the clustering algorithm can be manually checked, whether the clustering result is reasonable or not can be judged, and appropriate adjustment can be made according to the actual situation, for example, if the distance between some categories is very small, the categories can be merged again. The reasonability of the picture size set is improved, and meanwhile, the hit rate is guaranteed to be as high as possible.
In one possible implementation, determining a target picture size in the set of page sizes according to the desired picture size includes: acquiring a difference value set of the required picture size and the picture size in the page size set; and taking the picture size corresponding to the difference value with the minimum absolute value in the difference value set as the target picture size. Therefore, the target picture with the picture size closest to the required picture size is obtained, and the definition of the issued picture is ensured to a certain extent.
Optionally, determining a target picture size in the page size set according to the required picture size, further comprising: acquiring a difference value set of the required picture size and the picture size in the page size set; and taking the picture size corresponding to the difference value which is smaller than 0 and has the minimum absolute value in the difference value set as the target picture size. Therefore, on the basis of obtaining the target picture with the picture size closest to the required picture size, the target picture size is ensured to be larger than or equal to the value of the required picture size, and the stretching phenomenon can be prevented in the display process of the issued picture.
In a possible implementation manner, for the case that the acquired required picture size includes a picture height and a picture width, a difference set of the acquired required picture size and the picture sizes in the page size set is two-dimensional data, that is, a difference operation result of the required picture size and each picture size in the page size set is two differences, including a picture height difference and a picture width difference. At this time, the picture height difference value and the picture width difference value are summed, and the result of the summation is taken as the difference set in this case. Thus, the target picture size is determined according to the difference value with the smallest absolute value in the difference value set, or the target picture size is determined according to the difference value which is smaller than 0 and has the smallest absolute value in the difference value set. Optionally, for a case that the acquired required picture size includes only a picture height or only a picture width, and a difference set between the acquired required picture size and picture sizes in the page size set is one-dimensional data, a picture size corresponding to a difference value with a minimum absolute value in the difference set may be directly used as the target picture size, or a picture size corresponding to a difference value with a minimum absolute value that is smaller than 0 in the difference set may be directly used as the target picture size.
Illustratively, the acquired required picture scale includes only the required picture width, which is 508px, and the page size set includes picture widths of 470px, 480px, 490px, 500px, 510px and 520px, thereby acquiring a difference set of the required picture width and the picture widths in the page size set as: -38px, -28px, -18px, -8px and 2 px. Optionally, the picture width 510px corresponding to 2px with the smallest absolute value in the difference set may be used as the target picture width, or the picture width 500px corresponding to-8 px with the smallest absolute value and smaller than 0 in the difference set may be used as the target picture width.
In a possible implementation manner, the generating of the target picture issuing request based on the obtained target picture identifier and the determined target picture size may be: and generating a target picture issuing request by the picture processing tool. The picture processing tool is a packaged compression packet provided externally, and can provide service customization fields (such as information of picture size, watermark, picture compression parameters and the like) externally to service parties such as terminals and the like, the service parties send the required service customization fields to the picture processing tool, the picture processing tool internally packages the service customization fields according to general logic to generate a picture issuing request, and the generated picture issuing request supports access to a server.
Step 202, the terminal sends a target picture issuing request to a server.
In a possible implementation manner, the terminal may send the generated target picture issuing request to the server, so as to obtain the target picture through the server.
Step 203, the server receives a target picture issuing request sent by the terminal.
In a possible implementation manner, the server may receive a target picture issuing request sent by the terminal, and then may process the target picture issuing request.
And step 204, the server issues the target picture to the terminal according to the target picture issuing request.
In a possible implementation manner, issuing a target picture to a terminal according to a target picture issuing request includes: responding to the target picture cached, and issuing the cached target picture to the terminal; and responding to the condition that the target picture is not cached, acquiring the target picture through the source website server, and issuing the acquired target picture to the terminal.
In a possible implementation manner, in response to that the target picture is not cached, the target picture is obtained by the source website server, and after the obtained target picture is sent to the terminal, the method further includes: and caching the acquired target picture. The method and the system have the advantages that the pictures which are possibly requested by the user and are newly acquired by the source website server are cached, and the pictures can be directly issued when the user initiates an issuing request for the newly acquired pictures next time, so that the hit rate of the server is increased, and the delay of picture downloading is reduced.
