Description

Data transmission method and device for small program
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a data transmission method and apparatus for an applet, a server, and a storage medium.
Background
An applet is a mobile Application (APP) that can be used without downloading and installation, and is typically implemented based on other large APPs as carriers. For example, some large APPs provide an applet development platform, developers complete development of applets through the applet development platform and then publish the applets to a server of the large APP, and users can call applets through the large APP.
In the process of transmitting data of the existing small program between a logic layer and a rendering layer, a sending end needs to serialize the data into character strings and send the character strings to a system layer (or called NA layer), then the character strings are sent to a receiving end by the system layer, and the receiving end deserializes the character strings into available data after receiving the character strings. As shown in fig. 1, taking a logic layer of an applet as a sending end and a rendering layer as a receiving end as an example, data to be sent is a JS object, and since a system layer can only implement transfer of a character string, the JS object needs to be serialized into the character string first, and then the character string needs to be transferred to the system layer. Further, the system layer then sends the character string to the rendering layer of the applet, and the character string can be used by the rendering layer of the applet after the rendering layer is inversely sequenced into the JS object.
The data transmission performance of the transmission mode is greatly influenced by the data volume, when the data volume is increased, the data transmission performance is remarkably reduced due to the fact that a large amount of serialization and deserialization processing needs to be carried out, meanwhile, data in the system layer are transmitted based on the queue, external events such as user input and interface (UI) response can affect the data transmission speed in the system layer, and therefore delay exists when the data volume is large in data transmission.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a data transmission method of an applet.
As shown in fig. 2, the data transmission method of the applet includes the following steps:
step 201: and establishing a transmission protocol for object transmission between a sending end and a receiving end of the small program.
In this embodiment, one of the receiving end and the transmitting end is a logic layer of the applet, and the other is a rendering layer (also referred to as a view layer) of the applet. It will be appreciated that the method may be used to send data from and to the logic layer of the applet.
As shown in fig. 3, in general, the logic layer 301 of the applet is executed by a separate JS engine (Javascript Core), and the rendering layer 302 takes WebView (web page view) as a rendering carrier. In terms of architecture, the WebView and the JS engine are independent modules, so that data sharing cannot be directly carried out. Thus, when implemented, the transport protocol for this object transport can be established based on the JS virtual machine 303.
Specifically, the logic layer 301 and the rendering layer 302 of the applet each include a JS virtual machine 303, and the execution environment and the processed data of each JS virtual machine 303 are of the same format and type, so that data transmission and sharing can be realized between different JS virtual machines 303, and therefore, a transmission protocol for object transmission between the JS virtual machine 303 of the logic layer 301 and the JS virtual machine 203 of the rendering layer 302 can be established.
Step 202: and sending the object information of the object data of the sending end to the receiving end according to the transmission protocol.
Since the sending end and the receiving end of the applet establish a transmission protocol for object transmission, data transmission can be completed based on the transmission protocol. The data to be transmitted here specifically refers to object information of object data to be transmitted.
According to the embodiment of the invention, by establishing the transmission protocol for object transmission between the rendering layer and the logic layer of the applet, data can be directly transmitted between the rendering layer and the logic layer of the applet, so that the data processing amount in the data transmission process is reduced, the burden of a system layer is reduced, and the data transmission speed is improved.
Referring to fig. 4, fig. 4 is a flowchart of another embodiment of a data transmission method for an applet according to the present invention, which further defines a method for establishing a transmission protocol in the embodiment, compared with the embodiment shown in fig. 2. As shown in fig. 4, the data transmission method of the applet includes the following steps:
step 401, respectively establishing identity numbers bound with the logic layer and the rendering layer.
In this embodiment, first, an identity number (ID) is bound to each of the logic layer and the rendering layer, and the identity number is a unique identity number and is used as a unique identifier when data is transmitted. In implementation, the identity number bound between the logic layer and the rendering layer may be fixed; obviously, the bound identity number may also be changed, when data transmission is required, the logic layer and the rendering layer are bound with a unique identity number, the identity number is unbound after the data transmission is finished, after the identity number is unbound, data transmission cannot be continued because of the absence of an identifier for transmitting data, and when data transmission is required again, the identity number is bound again.
Further, in order to process the transmitted object data and register a corresponding processing function, the processing function may specifically participate in the existing processing function, which is not further limited and described herein.
Step 402: and establishing a transmission protocol for sending the object information according to the identity number.
The established transmission protocol is used for realizing data transmission, the data transmission is carried out according to the identity number of the receiving end, and the sending end and the receiving end which are determined according to the identity number are unique because the identity number is unique.
Generally, applets are implemented based on a JS virtual machine, in which case the established transport protocol is effectively a transport function for JS object transport based on identity number. Obviously, if the framework and the running environment of the applet are changed, the established transmission protocol can be adjusted according to the situation.
Step 403: and sending the object information of the object data of the sending end to the receiving end according to the transmission protocol.
As an alternative specific implementation, the step 403 includes:
object information of the object data is generated.
Since the logic layer and the rendering layer of the applet are both realized by relying on the JS virtual machine, in this embodiment, the data sent by the sending end to the receiving end is a JS object, that is, the object information of the object data is a JS object. In implementation, object information of the object data is generated according to the object data needing to be transmitted.
In one embodiment, the object data is copied and stored as an object data copy, and the stored object data copy is used as object information of the object data. In another embodiment, the memory address of the target data is used as the target information of the target data.
And based on the transmission protocol, the object information is sent to the receiving end by the sending end according to the identity number of the receiving end.
After determining the unique transmitting end and the unique receiving end, the data can be transmitted from the transmitting end to the receiving end based on the transmission protocol implementing the transmission function. Specifically, in the case where the applet is implemented based on the JS virtual machine, it is possible to transmit the object information of the object data from the determined transmitting end to the determined receiving end by calling the transfer function.
Optionally, after the object information is sent from the sending end to the receiving end according to the identity number of the receiving end based on the transmission protocol, the method further includes:
and calling a callback function to transparently transmit the object information of the object data.
The process is a callback process realized by a callback function, the transmission speed of the object information of the data object can be improved in a transparent transmission mode, meanwhile, interference between the transmission task and a transmission task established before is avoided, and the stability of data transmission is improved.
An embodiment of the present invention further provides a data transmission apparatus 500 of an applet, as shown in fig. 5, including:
