The method for updating the Flash player in the embodiment of the invention is applied to a device for updating the Flash player, the device is positioned in electronic equipment, the electronic equipment can be electronic equipment such as a mobile phone, a tablet computer or a personal computer, and the like, and can also be electronic equipment capable of playing Flash in the future.
Referring to fig. 1, an embodiment of a method for updating Flash according to an embodiment of the present invention includes:
s101, obtaining cache data of a target webpage embedded into a Flash player;
preferably, the file caching the version number of the Flash player may be different from the file caching the video played by the Flash player.
S102, determining whether the Flash player needs to update the version according to the cache data, if so, executing a step 103; if not, the following step S104 may be performed.
And S103, calling a system method calling function to update the Flash player version.
The embodiment of the invention obtains the cache data of the target webpage embedded into the Flash player, the cache data is stored in the file caching the version number of the Flash player, and the file caching the version number of the Flash player is different from the file caching the video played by the Flash player; and determining whether the Flash player needs to update the version according to the cache data, and calling a system method to call a function to update the version of the Flash player when determining that the Flash player needs to update the version. In the embodiment of the invention, because the version number of the Flash player and the playing data of the Flash player are not stored together, whether the Flash player needs to update the version can be determined according to the version number in the cache data, and the Flash player version can be updated automatically by calling the function through a system method when needed, so that the safety risk caused by the fact that the Flash player cannot be updated automatically in time in the prior art is avoided, the Flash player is updated automatically, a user does not need to update the player manually, and the safety risk is reduced.
Due to the problem of CDN cache, a Flash player that a web page gets to a server (servers described in this embodiment of the present invention are all resource servers corresponding to a target web page) may not yet be the latest version, so when the Flash player needs to be updated, the version of the Flash player that may be updated is not the latest, then an identifier is needed to record whether the latest Flash player has been updated, but in the running process of the Flash player, most of data is stored in the played video itself, and once the played video is closed, the data is also cleared from the memory, and when the Flash player runs next time, the data will be cached from the beginning. In order to record the version number which is sent by the server and needs to be updated to the Flash player, a local storage is needed to cache and record the version number, so that the file caching the version number of the Flash player is different from the file caching the video played by the Flash player, and the cache data of the version number of the Flash player is prevented from being removed when the video is closed.
In the embodiment of the invention, the ShareObject carried by the Flash player is adopted to cache the version number of the Flash player, and the specific mode is as follows:
so:SharedObject＝SharedObject.getLocal("xx","/")；
sOversion＝so.data[key]
wherein, XX is a folder name for storing the version number of the Flash player, key is the identification of the version number of the Flash player needing to be updated in ShareObject, and sversion is the version number of the Flash player in the cache data.
Further, the cache data described in the step S101 is cache data for caching a version number of the Flash player, where the cache data includes a first version number of the Flash player, and the Flash player includes a second version number of the Flash player; at this time, as shown in fig. 2, in some preferred embodiments of the present invention, the step S102 may specifically include:
s1021, comparing the first version number with the second version number, and determining whether the Flash player needs to be updated;
and S1022, determining that the Flash player needs to be updated when the first version number is different from the second version number or the first version number is empty.
Specifically, the version number sOverversion (the first version number) of the Flash player in the cache data is compared with the version number version (the second version number) of the Flash player (the version number is manually written in the Flash player during writing), if the sOverversion number is empty or the sOverversion number and the second version number are different, the Flash player is determined to need to be updated, and if the first version number is determined to be different from the second version number, the Flash player is determined not to need to be updated currently.
In some preferred embodiments of the present invention, when the Flash player may need to be updated in time during the operation process, in this case, the server is used as a driver, the Flash player establishes a long connection with the server, and monitors data sent by the server, and in this data, the server is required to inject the latest version number of the Flash player that needs to be updated (this version number needs to be consistent with the manually written version number in the latest Flash player). Therefore, when it is determined that the Flash player does not need to be updated currently, the method may further continue to monitor update data sent by the server, where the update data includes cache data of a third version number of the Flash player, and specifically, as shown in fig. 3, when it is determined that the Flash player does not need to be updated currently, the method further includes:
s104, monitoring data issued by a server;
the server is a server (also called a resource server) corresponding to the target webpage;
s105, if the updating data sent by the server is received, comparing the current version number of the Flash player with the third version number of the Flash player in the updating data, and determining whether the Flash player needs to be updated;
and S106, calling a system method calling function to update the Flash playing version when the Flash player is determined to need updating.
In the embodiment, the version number information of the server is received, the webpage is not directly updated to obtain the latest Flash player, and whether the webpage needs to be updated to obtain the latest Flash player version is judged through one-time version number verification of the Flash player, so that abnormal information of the server is effectively filtered.
Specifically, data issued by a server is monitored, if an operating Flash player receives update data sent by the server, the data is obtained to obtain a third version number newVersion carried by the data, the third version number newVersion number is compared with the current Flash player version number to determine whether the Flash player needs to be updated, if the third version number newVersion number is different from the current Flash player version number, the Flash player is determined to need to be updated, and a system method is called to call a function to update the Flash play version.
And updating and caching the third version number in cache data for caching the version number of the Flash player. In order to avoid that the latest Flash player cannot be updated due to Content Delivery Network (CDN) caching in the prior art, a system method call function is called to store the version number of the latest Flash player to be brushed in cache data, which is specifically implemented as follows:
so.data[key]＝newVersion；
so.flush()；
the method for caching the version number of the Flash player effectively avoids the situation that the Flash player does not brush the latest version due to CDN data delay.
At this time, the cache data in step S101 may also be a version number of the Flash player stored by a system method call function.
Further, in some embodiments of the present invention, before the step S101, the method further includes:
embedding the Flash player in the target webpage;
and marking a second version number of the Flash player in the Flash player.
At present, the conventional method for embedding a Flash player into a web page is mainly divided into three modes, namely an Object + embedded mode, an embedded mode and a SWF Object mode, and because the Object + embedded mode has better compatibility and can carry a large number of attributes required by the initialization of the Flash player, the Object + embedded mode is adopted to embed the Flash player in the embodiment of the invention. And assigning the id attribute as classID in the object tag is convenient for the following page to acquire the Flash player element. And marking a second version number of the Flash player in an id attribute. The above principle is used in this embodiment to embed a Flash player. And the method is also beneficial to being compatible with the browsers on the market, and avoids failure or abnormity of embedding a Flash player on some special browsers.
Further, as shown in fig. 4, the step of calling the system method call function to update the Flash player version in step S103 may specifically include:
s1031, monitoring a Flash player updating event which is preset in the target webpage by the server through an object element bearing the Flash player;
s1032, if the Flash player updating event of the Flash player is monitored, calling a system method calling function to update the Flash player version.
In the embodiment of the present invention, the Flash player is embedded into the browser in an object element form, and the object has an id attribute as an attribute that uniquely identifies this page element, that is, the div element (document. getelementbyid) carrying the Flash player can be obtained by setting the id of the object through the DOM tag. The Flash player can throw an event for updating the Flash player to a webpage through an external interface.
