Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a data transmission device structure of a hardware operating environment according to an embodiment of the present invention.

The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., wi-Fi interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the device structure shown in fig. 1 does not constitute a limitation of the data transmission device and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and a data transmission program may be included in the memory 1005 as one type of storage medium.
In the data transmission device shown in fig. 1, the network interface 1004 is mainly used for connecting to an external network and performing data communication with other network devices; the user interface 1003 is mainly used for connecting user equipment and communicating data with the user equipment; the apparatus of the present invention calls a data transmission program stored in the memory 1005 through the processor 1001 and executes the data transmission method provided by the embodiment of the present invention.
Based on the above hardware structure, the embodiment of the data transmission method of the invention is provided.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a data transmission method according to the present invention.
In a first embodiment, the data transmission method includes:
and step S10, when a communication request sent by the terminal equipment is received, a communication line between the terminal equipment and the terminal equipment is established according to the communication request.
It should be noted that, the execution body of the present embodiment may be a data transmission device, and the data transmission device may be a server device having a data processing function, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment, and in this embodiment, a server device is described as an example.
It should be noted that the scheme can be applied to a server and used for data transmission between the server and terminal equipment corresponding to a front-end browser. The present embodiment is applicable to various scenes, for example, the present embodiment may be applied to various scenes such as a live broadcast data transmission scene, an image data transmission scene, and a web page data transmission scene, and may also be applied to other types of scenes, which are not limited in this embodiment, and in this embodiment, a live broadcast data transmission scene is taken as an example for explanation.
It should be understood that in a live data transmission scenario, a user may use a front-end browser to perform live viewing, so the front-end browser needs to acquire live data from a server in real time according to live information selected by the user, and then parse the live data to display live video to the user.
It can be understood that, for data transmission in the above scenario, most of the prior art adopts a polling mode, and the browser sends http requests to the server at intervals, and then the server returns the latest data to the client. Whether long polling or short polling, the browser needs to initiate a request each time to acquire a result, the result has certain passivity, and the server cannot actively send data to the browser. Therefore, the data transmission by the polling method wastes the server connection resources and may affect the server performance and the live broadcast effect, i.e. the existing data transmission method cannot achieve a better data transmission effect in the scene.
It should be noted that, based on the above-mentioned problem, the data transmission is not carried out by adopting a polling mode, but by adopting a new mode, based on the mode, the browser and the server can establish persistent connection only by completing handshake once, and then both sides can send data, which fully solves the problem that the server cannot actively push data to the browser, and reflects the real-time performance of data transmission. In addition, the connection closing time can be controlled by the method, and the connection can be automatically closed as long as a certain party of the server or the client actively closes the connection. In addition, the mode has a reconnection mechanism, and reconnection can be automatically performed when connection is not enabled and is not in a closed state, so that the two parties can be ensured to successfully send data as far as possible.
It will be appreciated that based on the above-described concept, in order to establish a connection between the server and the terminal device where the front-end browser is located in this way, the server may continually monitor for a communication request, upon receipt of a communication request sent by the terminal device, establish a communication line with the terminal device in accordance with the communication request.
It is understood that a communication line can be understood as a temporary communication connection between a server and a terminal device. In order to ensure information security and achieve better data transmission effect, the server in the scheme does not directly establish communication connection with the terminal equipment for data transmission after receiving the communication request, but establishes a communication line with the terminal equipment only according to the communication request, then carries out handshake through the communication line once, establishes communication connection between the server and the terminal equipment after handshake success, and can realize two-way communication between the server and the terminal equipment through the communication connection.
Step S20, when a handshake request sent by the terminal device through the communication line is received, a communication connection with the terminal device is established according to the handshake request.
It should be understood that after the terminal device and the server establish a communication line, the terminal device may send a handshake request, and the server may feedback a handshake response according to the handshake request after receiving the handshake request sent by the terminal device through the communication line, thereby completing a handshake operation between the terminal device and the server to establish a communication connection between the server and the terminal device.
It can be appreciated that after the communication connection between the server and the terminal device is established in the above manner, the subsequent data exchange can be directly realized based on the communication connection, so that the communication request is not required to be retransmitted, and the bandwidth resource is saved. The communication connection is a bi-directional communication connection, and the server and/or the terminal device may transmit data through the communication connection or receive data through the communication connection, which is not limited in this embodiment.
And step S30, data related to the front-end browser is sent to the terminal equipment through the communication connection.
It should be appreciated that in the case where the above communication connection exists between the server and the terminal device, if the data associated with the front-end browser is generated in the server, the server may directly send the data associated with the front-end browser to the terminal device through the communication connection, so that the terminal device displays the data on the front-end browser. Compared with the existing polling mode, the communication connection in the scheme has a bidirectional communication function, data can be flexibly sent to the terminal equipment through the communication connection according to actual conditions without sending the data to the terminal equipment under the condition of receiving the request of the terminal equipment, so that the waste of server connection resources is avoided, and a better data transmission effect can be achieved.
In a specific implementation, for example, in a live broadcast data transmission scene, a user watches live broadcast through a front-end browser, when the user accesses a live broadcast room is detected, communication connection between a server and terminal equipment can be established through the mode, then the server can directly transmit live broadcast data related to the live broadcast to the terminal equipment through the communication connection according to actual conditions, the terminal equipment can display live broadcast content to the user according to the received live broadcast data, so that the front end can display data in real time after the back-end data are generated, and the consumption condition of server resources is small.
It should be understood that, in addition to the above effect, the communication connection in the present solution can also be flexibly closed, that is, the communication connection may be closed by a server or a terminal device, and the closing time of the connection may be controlled, so long as the server or a party of the terminal device actively closes the connection, the connection may be automatically closed. In addition, the mode has a reconnection mechanism, and when the connection is not enabled and the communication connection is not actively closed by the server or the terminal equipment, reconnection can be automatically carried out, so that the two parties can be ensured to send data as far as possible, and the condition of data transmission failure is avoided.
In this embodiment, when a communication request sent by a terminal device is received, a communication line between the terminal device and the terminal device is established according to the communication request; when a handshake request sent by the terminal equipment through the communication line is received, establishing communication connection with the terminal equipment according to the handshake request; and sending the data related to the front-end browser to the terminal equipment through the communication connection. Compared with the existing polling mode, the server and the terminal equipment in the scheme can establish the durable communication connection only by completing one-time handshake, and then both sides can send data, so that the real-time performance of data transmission is reflected, the waste of server connection resources can be avoided, and the data transmission effect is improved.
In an embodiment, as shown in fig. 3, a second embodiment of the data transmission method according to the present invention is proposed based on the first embodiment, and the step S30 includes:
in step S301, it is detected whether there is data in a target channel, where the target channel is used to store data related to a front-end browser.
It should be noted that, in the present solution, the data transmission may be implemented by using a coroutine mechanism of the GO language, and fig. 4 may be referred to as a whole flow chart of data transmission in fig. 4. After the communication connection between the server and the terminal device is established, the data transmission flow of the scheme can be divided into four major parts, which are respectively: read coroutine, write coroutine, timed task coroutine, and output coroutine.
Note that a coroutine is a existence that is lighter than a thread, just as a process can own multiple threads, a thread can own multiple coroutines. Thus, a process may be composed of multiple threads, while a thread may be composed of multiple threads, as this embodiment is not limiting.
It should be understood that the reading protocol in this scheme is responsible for reading the request of the terminal device, and the output protocol is responsible for pushing data to the terminal device. The write-assisted procedure and the timing task-assisted procedure are both specifically responsible for processing the data logic, the write-assisted procedure is responsible for processing the scenario requested by the terminal device, and the timing task-assisted procedure is responsible for processing the scenario actively pushed by the server, which is not limited in this embodiment.
It should be noted that, in this embodiment, the three channels (channels) are a first channel (channel-1), a second channel (channel-2), and a target channel (channel-3), where the target channel may be a channel for storing data related to a front end browser to be sent, the first channel may be a channel for storing request information sent by a terminal device, and the second channel may be a channel for storing request data.
It should be appreciated that the server may perform an output pass operation to detect whether data is present in the target channel, send the data to the terminal device when data is present in the target channel, and continue to wait for data to be acquired when data is not present in the target channel.
Further, in order to more accurately detect whether data exists in the target channel, transmission efficiency is improved, target channel information corresponding to the target channel can be obtained, a data storage state corresponding to the target channel is determined according to the target channel information, and whether data exists in the target channel is detected according to the data storage state corresponding to the target channel.
Step S302, when data exists in the target channel, acquiring target data in the target channel.
It will be appreciated that in the case where there is data in the target channels, it is stated that these data need to be transmitted to the terminal device, and therefore, in this case, the data in the target channels can be acquired and referred to as target data.
And step S303, the target data is sent to the terminal equipment through the communication connection, so that the terminal equipment displays the target data on a front-end browser.
It should be appreciated that after data is present in the target channel and the target data is obtained from the target channel, the server may send the target data to the terminal device over the communication connection. After receiving the target data, the terminal device can display the target data on the front-end browser.
In a specific implementation, when live broadcast data exists in the target channel, the server may acquire the target live broadcast data from the target channel, and send the target live broadcast data to the terminal device through the communication connection. After receiving the target live broadcast data, the terminal equipment can play live broadcast in the front-end browser according to the target live broadcast data.
In this embodiment, whether data exists in a target channel is detected, where the target channel is used to store data related to a front-end browser; when data exists in the target channel, acquiring target data in the target channel; and sending the target data to the terminal equipment through the communication connection so that the terminal equipment displays the target data on a front-end browser. Therefore, the data in the target channel can be timely and actively sent to the terminal equipment through communication connection, so that the terminal equipment can timely display the front end, and the timeliness of data transmission is improved.
Further, the scheme further includes a read co-procedure operation, and the request of the terminal device is read through the read co-procedure, and before step S30, the method further includes:
performing read-co-procedure operation to detect whether the terminal equipment sends request information; if the terminal equipment sends the request information, the request information sent by the terminal equipment is read; and storing the request information sent by the terminal equipment into a first channel.
It should be understood that the server may perform a read co-procedure operation to detect whether the terminal device has transmitted the request information, read the request information when the terminal device has transmitted the request information, and continuously wait for the request information of the terminal device when the terminal device has not transmitted the request information.
It will be appreciated that in case the terminal device has transmitted the request information, the request information transmitted by the terminal device may be read and stored in the first channel.
Further, the scheme further includes a write-assisted procedure operation, and the scenario requested by the terminal device is processed through the write-assisted procedure, and before step S30, the method further includes:
performing write cooperative operation to detect whether data exists in a first channel, wherein the first channel is used for storing request information sent by terminal equipment; acquiring first data in the first channel when the data exists in the first channel; detecting a data type of the first data; and when the data type is a first preset type, storing the first data into a second channel. And when the data type is a second preset type, performing heartbeat detection according to the first data. And closing the communication connection when the data type is a third preset type.
It should be noted that, referring to fig. 4, the first preset type in the present embodiment may be an msg type, the second preset type may be a ping type, and the third preset type may be a close type.
It should be appreciated that the server may perform a write-co-procedure to detect whether data is present in the first channel, where the data is present in the first channel may be referred to as first data. First data in the first channel may be acquired and a data type of the first data may be detected.
When the data type is the first data type, that is, the data type of the first data is the msg type, the first data can be stored in the second channel, and the msg data is returned by calling the method, so that the msg data is stored in the target channel.
And returning pong to perform heartbeat detection when the data type is the second data type, namely the data type of the first data is the ping type.
When the data type is the third data type, i.e. the data type of the first data is the close type, all channels may be closed and the communication connection is closed (in this embodiment the communication connection is called ws).
In this embodiment, through the read-write cooperative procedure and the write cooperative procedure operation, the server can timely read the request information of the terminal device and make corresponding feedback, so that the real-time performance of data transmission is further improved, and a better data transmission effect can be achieved.
In an embodiment, as shown in fig. 5, a third embodiment of the data transmission method according to the present invention is provided based on the first embodiment or the second embodiment, and in this embodiment, the description is based on the first embodiment, and before the step S30, the method further includes:
step S01, timing task cooperative operation is performed to detect whether data exists in the second channel.
It should be noted that the scheme also includes timing task cooperative operation, and the scenario of active pushing by the timing task cooperative processing server is included.
It should be appreciated that the server may perform a timed task co-program operation to detect whether data is present in the second channel, wait for the second channel to acquire data if no data is present in the second channel, and assign a value to a parameter of the timed task.
Step S02, when data exists in the second channel, acquiring the current time.
It should be appreciated that in the case where there is data in the second channel, the current time may be acquired, and the last data generation time corresponding to the second channel is acquired, and the interval time is calculated according to the current time and the last data generation time.
It will be appreciated that the interval time may be compared with a preset time, and when the interval time exceeds the preset time, it is determined that the current time meets a third preset time condition. The preset time may be set according to practical situations, for example, the preset time may be set to 30S, which is not limited in this embodiment. In a specific implementation, when the difference between the current time and the last data generation time exceeds 30S, it is determined that the timeout time is reached, that is, the current time meets a third preset time condition.
It can be understood that when the interval time does not exceed the preset time, whether the current time is a multiple of the first preset value can be further detected, and when the current time is a multiple of the first preset value, the current time is judged to meet the first preset time condition. The first preset value may be set according to practical situations, for example, the preset time may be set to 5S, which is not limited in this embodiment. In a specific implementation, when the current time is a multiple of 5S, it is determined that the current time meets a first preset time condition.
It can be understood that when the interval time does not exceed the preset time, whether the current time is a multiple of the second preset value can be further detected, and when the current time is a multiple of the second preset value, the current time is judged to meet the second preset time condition. The second preset value may be set according to practical situations, for example, the preset time may be set to 30S, which is not limited in this embodiment. In a specific implementation, when the current time is a multiple of 30S, it is determined that the current time meets a second preset time condition.
It should be understood that, since there is an overlapping portion between the multiple of 5S and the multiple of 30S, in order to achieve a better detection effect, it is preferable in this embodiment that: detecting whether the current time is a multiple of a second preset value or not, and then detecting whether the current time is a multiple of the first preset value or not. In addition, other detection sequences are possible, and the present embodiment is not limited thereto.
Step S03, when the current time accords with a first preset time condition, acquiring first browser data related to a front-end browser from a first preset database.
It should be noted that, the first preset database in this embodiment may be a redis database, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment. When the current time meets the first preset time condition, the basic data required by the front-end browser can be acquired from the redis database, and the basic data is called as first browser data in the embodiment.
Step S04, storing the first browser data into a target channel.
It should be appreciated that after the first browser data is obtained, the first browser data may be stored in the target channel, waiting for the output protocol to send the data in the target channel to the terminal device.
It should be noted that, the second database in this embodiment may be an es database, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment. When the current time meets the second preset time condition, the common data required by the front-end browser can be obtained from the es database, and the common data is called second browser data in the embodiment.
It should be appreciated that after the second browser data is obtained, the second browser data may be stored in the target channel awaiting the output pass to send the data in the target channel to the terminal device.
It should be noted that when the current time meets the third preset time condition, all channels may be closed, and the communication connection may be closed.
In this embodiment, a timing task cooperative operation is performed to detect whether data exists in the second channel; when data exists in the second channel, acquiring the current time; when the current time accords with a first preset time condition, acquiring first browser data related to a front-end browser from a first preset database; and storing the first browser data into a target channel. The method comprises the steps that a timing task cooperative distance processing server can be used for actively pushing a scene, data related to a front-end browser are obtained and stored in a target channel, and waiting for an output cooperative distance to send the data in the target channel to a terminal device through communication connection between the server and the terminal device.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a data transmission program, and the data transmission program realizes the steps of the data transmission method when being executed by a processor.
Because the storage medium adopts all the technical schemes of all the embodiments, the storage medium has at least all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted here.
In addition, referring to fig. 6, an embodiment of the present invention further proposes a data transmission device, where the data transmission device includes:
and the communication line module 10 is used for establishing a communication line with the terminal equipment according to the communication request when the communication request sent by the terminal equipment is received.
It should be noted that the scheme can be applied to a server and used for data transmission between the server and terminal equipment corresponding to a front-end browser. The present embodiment is applicable to various scenes, for example, the present embodiment may be applied to various scenes such as a live broadcast data transmission scene, an image data transmission scene, and a web page data transmission scene, and may also be applied to other types of scenes, which are not limited in this embodiment, and in this embodiment, a live broadcast data transmission scene is taken as an example for explanation.
It should be understood that in a live data transmission scenario, a user may use a front-end browser to perform live viewing, so the front-end browser needs to acquire live data from a server in real time according to live information selected by the user, and then parse the live data to display live video to the user.
It can be understood that, for data transmission in the above scenario, most of the prior art adopts a polling mode, and the browser sends http requests to the server at intervals, and then the server returns the latest data to the client. Whether long polling or short polling, the browser needs to initiate a request each time to acquire a result, the result has certain passivity, and the server cannot actively send data to the browser. Therefore, the data transmission by the polling method wastes the server connection resources and may affect the server performance and the live broadcast effect, i.e. the existing data transmission method cannot achieve a better data transmission effect in the scene.
It should be noted that, based on the above-mentioned problem, the data transmission is not carried out by adopting a polling mode, but by adopting a new mode, based on the mode, the browser and the server can establish persistent connection only by completing handshake once, and then both sides can send data, which fully solves the problem that the server cannot actively push data to the browser, and reflects the real-time performance of data transmission. In addition, the connection closing time can be controlled by the method, and the connection can be automatically closed as long as a certain party of the server or the client actively closes the connection. In addition, the mode has a reconnection mechanism, and reconnection can be automatically performed when connection is not enabled and is not in a closed state, so that the two parties can be ensured to successfully send data as far as possible.
It will be appreciated that based on the above-described concept, in order to establish a connection between the server and the terminal device where the front-end browser is located in this way, the server may continually monitor for a communication request, upon receipt of a communication request sent by the terminal device, establish a communication line with the terminal device in accordance with the communication request.
It is understood that a communication line can be understood as a temporary communication connection between a server and a terminal device. In order to ensure information security and achieve better data transmission effect, the server in the scheme does not directly establish communication connection with the terminal equipment for data transmission after receiving the communication request, but establishes a communication line with the terminal equipment only according to the communication request, then carries out handshake through the communication line once, establishes communication connection between the server and the terminal equipment after handshake success, and can realize two-way communication between the server and the terminal equipment through the communication connection.
And the communication connection module 20 is configured to, when receiving a handshake request sent by the terminal device through the communication line, establish a communication connection with the terminal device according to the handshake request.
It should be understood that after the terminal device and the server establish a communication line, the terminal device may send a handshake request, and the server may feedback a handshake response according to the handshake request after receiving the handshake request sent by the terminal device through the communication line, thereby completing a handshake operation between the terminal device and the server to establish a communication connection between the server and the terminal device.
It can be appreciated that after the communication connection between the server and the terminal device is established in the above manner, the subsequent data exchange can be directly realized based on the communication connection, so that the communication request is not required to be retransmitted, and the bandwidth resource is saved. The communication connection is a bi-directional communication connection, and the server and/or the terminal device may transmit data through the communication connection or receive data through the communication connection, which is not limited in this embodiment.
And the data sending module 30 is used for sending the data related to the front-end browser to the terminal equipment through the communication connection.
It should be appreciated that in the case where the above communication connection exists between the server and the terminal device, if the data associated with the front-end browser is generated in the server, the server may directly send the data associated with the front-end browser to the terminal device through the communication connection, so that the terminal device displays the data on the front-end browser. Compared with the existing polling mode, the communication connection in the scheme has a bidirectional communication function, data can be flexibly sent to the terminal equipment through the communication connection according to actual conditions without sending the data to the terminal equipment under the condition of receiving the request of the terminal equipment, so that the waste of server connection resources is avoided, and a better data transmission effect can be achieved.
In a specific implementation, for example, in a live broadcast data transmission scene, a user watches live broadcast through a front-end browser, when the user accesses a live broadcast room is detected, communication connection between a server and terminal equipment can be established through the mode, then the server can directly transmit live broadcast data related to the live broadcast to the terminal equipment through the communication connection according to actual conditions, the terminal equipment can display live broadcast content to the user according to the received live broadcast data, so that the front end can display data in real time after the back-end data are generated, and the consumption condition of server resources is small.
It should be understood that, in addition to the above effect, the communication connection in the present solution can also be flexibly closed, that is, the communication connection may be closed by a server or a terminal device, and the closing time of the connection may be controlled, so long as the server or a party of the terminal device actively closes the connection, the connection may be automatically closed. In addition, the mode has a reconnection mechanism, and when the connection is not enabled and the communication connection is not actively closed by the server or the terminal equipment, reconnection can be automatically carried out, so that the two parties can be ensured to send data as far as possible, and the condition of data transmission failure is avoided.
In this embodiment, when a communication request sent by a terminal device is received, a communication line between the terminal device and the terminal device is established according to the communication request; when a handshake request sent by the terminal equipment through the communication line is received, establishing communication connection with the terminal equipment according to the handshake request; and sending the data related to the front-end browser to the terminal equipment through the communication connection. Compared with the existing polling mode, the server and the terminal equipment in the scheme can establish the durable communication connection only by completing one-time handshake, and then both sides can send data, so that the real-time performance of data transmission is reflected, the waste of server connection resources can be avoided, and the data transmission effect is improved.
In one embodiment, the data sending module 30 is further configured to detect whether there is data in a target channel, where the target channel is used to store data related to a front-end browser; when data exists in the target channel, acquiring target data in the target channel; and sending the target data to the terminal equipment through the communication connection so that the terminal equipment displays the target data on a front-end browser.
In an embodiment, the data sending module 30 is further configured to obtain target channel information corresponding to a target channel; determining a data storage state corresponding to the target channel according to the target channel information; and detecting whether data exists in the target channel according to the data storage state.
