Specific embodiment

In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality The attached drawing in example is applied, the technical solution in the embodiment of the present application is clearly and completely described, it is clear that described implementation Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common Technical staff's all other embodiments obtained without making creative work should all belong to the application protection Range.

Embodiment one

Webp forms often face the access end (such as browser) of network picture to this as a kind of novel picture format Supportive (compatibility) problem (demand) of form, and then influence access or the response efficiency of network picture.For example, browsing When device is by the picture of network access server, if without supportive detection, server is directly smaller by " volume " Webp format pictures are sent to browser, it would be possible to since browser does not support the picture of the form that loading is caused to render failure, At this moment server needs to retransmit the picture of extended formatting, so as to influence network picture access or response efficiency and user's body It tests.

When Webp format pictures in a network environment in use, access end send access request after, if accessed end energy Enough know that access end has the ability for supporting Webp format pictures, then access end can be needed to the picture that accesses with Webp forms Mode be sent to access end, since Webp format pictures are more small than extended formatting picture, thus can save transmission money Access (response) efficiency of network picture is improved in source.Referring to Fig. 1, which shows the embodiment of the present application from the angle of access end The flow of the method for one access network picture.The embodiment includes：

Step S101：Preset standard Webp format pictures are obtained, extract at least one category of standard Webp format pictures The property value of property；

Access end can obtain preset standard Webp format charts before network picture access is carried out or in access process Piece, using standard Webp format picture test access ends to the supportive of Webp format pictures.Here preset standard is obtained The operation of Webp format pictures can carry out under certain trigger condition, which can be embodied directly in the finger of people It enables, for example, before access end carries out network picture access, pops up dialog box, ask whether to need to carry out Webp format charts The supportive detection of piece if receiving confirmation message from the user, triggers the step for obtaining preset standard Webp format pictures Suddenly；The trigger condition may be embodied in preset condition and be met, for example, after access end accesses certain server for the first time, It monitors the supportive detection message that server is sent, then triggers the step of obtaining preset standard Webp format pictures.

Here preset standard Webp format pictures are whether support Webp format pictures for test access end one Carrier, itself is not as the operation object of the application based on Webp format pictures.For example, passing through browser access server Network picture during, preset standard Webp format pictures are not the Target Photos that browser will access, but pre- in advance The Webp format picture for being located at server end or browser end put or be generated in advance according to certain rule.Due to this Webp format pictures only need to play the role of detecting whether browser supports Webp format pictures, therefore, in practical application mistake The Webp format pictures to improve supportive detection speed and efficiency, are usually set as a standardization picture, " mark by Cheng Zhong Standardization " can be presented as fixed width, height or fixed size etc..

It should be noted that：Preset standard Webp format pictures can be stored in advance in access end local, can also lead to Network download is crossed, which kind of mode specifically to depend on the Starting mode of supportive detection using：When being started by access end, access end Before access request is sent, supportive detection process can be completed from the local preset standard Webp format pictures that recall；When by When accessed end starts, access end can be received from the pre-stored standard Webp format pictures in accessed end, then utilized Standard Webp format pictures complete the supportive detection process of access end.

Step S102：Loading renders the standard Webp format pictures；

Step S103：Judge the property value of the attribute extracted before loading rendering and the category of respective attributes after loading rendering Whether property value is identical, if identical, performs step S104：If it is not the same, then perform step S105；

After loading renders, in fact it could happen that two kinds of situations：When loading renders successfully, load render successfully show as it is pre- It is marked with quasi- Webp format pictures not change before and after loading, i.e., the loading of standard Webp format pictures is no after rendering lacks Phenomena such as mistake, corrupted, distortion, based on this, whether the property value that front and rear respective attributes can be rendered by comparing loading is identical Mode judge whether loading renders successfully, if property value is identical, illustrate load rendering after do not change, show access end Support Webp format pictures；Second is that loading renders failure, loading, which renders, unsuccessfully shows as default Webp format pictures in loading wash with watercolours Changed after dye, i.e., standard Webp format pictures fail to load or distortion, defect etc. occur now after loading rendering As, based on this, loading render after result (pictures can be still behaved as) attribute it is inevitable loaded with it render before go out Existing difference, so as to show that access end does not support Webp format pictures.In actual application, to improve the accuracy of detection, Multiple attributes can be set to be detected jointly, i.e., the property value of multiple attributes is extracted in step S101, after loading renders, The property value of result respective attributes after this multiple property value is rendered with loading in step s 103 is compared, if homogeneously Together, then it is assumed that access end supports Webp format pictures.

The realizations such as program language Javascript, Java may be used in above-mentioned steps S101~S103.Moreover, in practical inspection During survey, preset standard Webp format pictures can also be carried out to special coding according to the different of detection triggering mode, with Acceleration detection.For example, when detecting trigger request by startup of server, access end can receive from accessed end, use Standard Webp format pictures after base64 codings, and realize detection using standard Webp pictures.It illustratively provides below The detection core code write with Javascript language：

The base64 code levels of the standard Webp pictures given in the code segment are 2, in the LOAD (loadings by picture Render) operation after, if the height of picture remains as 2, may indicate that access end can support Webp format pictures, otherwise, Then illustrate that access end does not support Webp format pictures.

Step S104：The access request that network picture is accessed with Webp forms is sent, receives and network is returned to Webp forms The response message of picture realizes the access of network picture；

By aforementioned detecting step, if access end can support Webp format pictures, to accessed end send with Webp forms access the access request of network picture, and accessed end is made to return to network by the requirement of access request with Webp forms The response message of piece, access end realizes the access of network picture after receiving the response message, so as to utilize Webp format pictures Advantage reduce transfer resource.The response message that the accessed end that access end receives returns to network picture with Webp forms can be with It is that Webp form of the accessed end in advance in preset plurality of picture form directly returns or accessed end is being learnt After access end " accessing network picture with Webp forms ", the picture of extended formatting is converted into Webp format pictures and is sent to access End.

Step S105：The access request that network picture is accessed with the form that can be supported other than Webp forms is sent, Receive the access for the response message realization network picture that network picture is returned with the form that can be supported other than Webp forms；

By aforementioned detecting step, if access end does not support Webp format pictures, to accessed end send with The extended formatting (for example, JPG forms) that access end other than Webp forms can be supported accesses the access request of network picture, makes Accessed end is returned to the response message of network picture by the requirement of access request with Webp forms, and access end receives the response and disappears The access of network picture is realized after breath.

For the present embodiment during network picture is accessed, access end judges whether its own supports Webp format pictures, has Picture format is properly received conducive to access end, so as to fulfill the access of network picture：When access end supports Webp format pictures, Webp format pictures are received from accessed end and realize picture access, when access end does not support Webp format pictures, from accessed Other pictures that can be supported that end receives except Webp format pictures realize picture access, due in equal image quality condition Under, " volume " of Webp format pictures is smaller than extended formatting picture, so as to improve transmission speed, and then improves network picture Access efficiency.

Embodiment two

In the above-described embodiments, access end is judged after supporting Webp format pictures, by receiving accessed end according to visit Ask that the Webp format pictures that request returns realize goal of the invention.But it if when same access end accesses every time, carries out Webp format pictures are supportive to judge operation, and actually unnecessary repetition causes the waste of process resource.For this purpose, this reality Example is applied preferably after first time carries out the supportive judgement of Webp format pictures, if access end supports Webp format pictures, into Line flag, setting Webp format pictures support mark, in this way, when the access end carries out next access, it may not be necessary to carry out Webp again Format picture is supportive to judge operation, and directly takes appropriate measures.Here setting Webp format pictures support that mark can be with Including the following two kinds realization method：

One of mode：Webp format pictures is directly set to support mark by access end.In this way the main reason for It is：On the one hand, the executive agent as the supportive detection of Webp format pictures can know itself to Webp format charts in time The support implementations of piece can promptly set Webp format pictures to support mark, when being conducive to save the entirety of network access Between；On the other hand, due to being locally located, without testing result is notified accessed end, so as to avoid transmission process The mistake brought；In another aspect, this traffic sign placement mode is completed by large number of access end itself, if passing through register Storage, then only need a small amount of register, so as to reduce storage resource, is conducive to the live load for disperseing accessed end. During specific setting, which may be provided in the cookie file that access end locally maintains.

The two of mode：Webp format pictures corresponding with access end is set to support mark by accessed end.By this way Setting Webp format pictures support mark to need access end that testing result is sent to accessed end, so that accessed end receives Webp format pictures corresponding with access end is set to support mark according to the message after the message.In this way the reason of, exists In：In general, the processing capacity of accessed end is stronger, disappear when multiple access ends send testing result to same accessed end After breath, unified, concentrated setting, the mode so as to be set respectively than each access end there can be whole speed faster by accessed end Degree.After setting in this way, when access end carries out network picture access, accessed end can be asked according to its pre-stored figure Piece form carries out the form response of " active "：If access end supports Webp format pictures, accessed end is received with Webp lattice The picture of formula response is to realize the access of network picture, and otherwise, receiving accessed end, (such as JPG forms) responds in other formats Picture to realize the access of network picture.

After Webp format pictures being set to support mark by aforementioned manner, it may need to cancel the setting in some cases. For example, although access end confirms that itself can support Webp format pictures, based on a variety of causes, access end shows Webp forms The effect of picture may may be more desirable to use other as the user to network picture access in this case not as expected Format picture, even if it will occupy more storage resources or transfer resource.For this purpose, the application is preferably having appreciated that access end pair In the case that Webp format pictures are supported, access end is also detected the actual displayed effect of Webp format pictures, then sentences Whether its display effect of breaking meets preset condition, if it is satisfied, then can continue to retain Webp format pictures support mark；If It is unsatisfactory for, then eliminates previously positioned Webp format pictures and support to indicate or further, Webp format pictures is set not prop up Hold mark.It operates in this way, although some access ends can support Webp format pictures, due to showing Webp format pictures Display effect it is bad, then may be pushed into " blacklist ", so as to by its from support Webp format pictures access end in filter Fall.

It should be noted that：It is corresponding with the two ways that above-mentioned setting Webp format pictures support mark, eliminate Webp Format picture supports the mode of mark that can also include two kinds：One kind is directly to be disappeared by access end the support mark；It is another It is that access end detects to need to cancel after Webp format pictures support mark, by the message with " Webp format pictures can not be by The form of support " is sent to accessed end, so that the Webp corresponding with access end set is eliminated in accessed end according to the message Format picture supports mark.

Webp format pictures based on above-mentioned setting support mark, and the application can deform on the basis of embodiment one Mode (embodiment two), i.e. access end can first judge whether to set Webp format pictures when carrying out network picture access next time It supports mark, and then takes appropriate measures.Referring to Fig. 2, the figure shows the flows of this mode of texturing.The flow includes：

Step S201：Judge whether that Webp format pictures support mark, if it is present performing step S205；Such as Fruit is not present, then enters step S202；

Step S202：Preset standard Webp format pictures are obtained, extract at least one category of standard Webp format pictures The property value of property；

Step S203：Loading renders the standard Webp format pictures；

Step S204：Judge the property value of the attribute extracted before loading rendering and the category of respective attributes after loading rendering Whether property value is identical, if identical, performs step S205：If it is not the same, then perform step S206；

Step S205：The access request that network picture is accessed with Webp forms is sent, receives accessed end with Webp forms The response message for returning to network picture realizes the access of network picture；

Step S206：The access request that network picture is accessed with the form that can be supported other than Webp forms is sent, Receive the response message realization network that accessed end returns to network picture with the form that can be supported other than Webp forms The access of piece.

Embodiment three

Both of the aforesaid embodiment describes from the angle of access end and realizes network picture access based on Webp format pictures Situation is described below from the angle of accessed end, i.e., a kind of response to network picture access request provided in this embodiment Method.Referring to Fig. 3, the figure shows the streams of the method for the response to network picture access request of the angle description from accessed end Journey, the flow include：

Step S301：It receives and sends the supportive detection message of Webp format pictures to access end after access request, to touch It sends out access end and obtains preset standard Webp format pictures, and extract the attribute of at least one attribute of standard Webp format pictures Value；

It, under normal conditions will be with traditional picture format (ratio after accessed end receives the access request of access end transmission Such as JPG forms) response access end request.In the present embodiment, accessed end is first triggered before the request of response access end The detection work of Webp format pictures whether is supported access end, targetedly to respond access end according to testing result Request.Accessed end receives and sends the supportive detection message of Webp format pictures to access end after access request, so as to trigger Access end obtains preset standard Webp format pictures, and extracts the property value for subsequent step multilevel iudge.Need what is illustrated It is：Here preset standard Webp format pictures can be that accessed end carrying is sent to access end in message is detected, It can be after accessed end triggering access end, be obtained from its own or other equipment by access end.

Step S302：Receive access end will load render the property value that is extracted before the standard Webp format pictures with After loading renders the property value of respective attributes that extracts be compared whether identical judging result；If the judgement As a result it is identical for property value, then perform step S303；If the judging result is differed for property value, step is performed S304；
