Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
The embodiment of the present disclosure provides a method for transmitting data, which may be implemented when at least two devices are mutually matched, for example, when a data transmitting end and a data receiving end are mutually matched, where the data transmitting end and the data receiving end may be a terminal or a server. The data transmission process may be that the data sending end sends data to the data receiving end, and the data receiving end executes processing after receiving the data. When a plurality of data sending terminals send a large amount of data to a data receiving terminal, in order to improve data transmission efficiency and ensure that a large amount of data can be processed by the data receiving terminal, the plurality of data sending terminals may issue the data in a terminal or a server, and the data receiving terminal acquires the data from the terminal or the server. When the method is applied in the scene, two processes are provided, one is a process of sending data, and the other is a process of receiving data.
In order to facilitate introduction, a data sending end in a data sending process is not marked as a first terminal, and a data receiving end is marked as a server. The server may be a server of a Kafka platform, which is an open source streaming platform that can accept any data.
As shown in fig. 1, a schematic flow chart of the first terminal sending data to the server is as follows:
in step 101, a data sending end obtains data to be sent.
The first terminal is a main body for executing and acquiring data to be transmitted, and the specific executing main body may be a middleware integrated on the first terminal, where the middleware is an independent system software or service program and is located between a hardware operating system and application software. The middleware may only have a program for transmitting data or may have a program for transmitting data and a program for receiving data at the same time, for example, the programs for transmitting data and receiving data are compressed together in the form of jar packets, and since the data for transmission or reception may be data transmitted to the Kafka platform, the jar packet of the middleware may be named "mta _ kafkaSdk", and integrated in the first terminal, and when data needs to be transmitted, the program for transmitting data is used, and when data needs to be received, the program for receiving data is used.
When the middleware of the first terminal needs to send data, for example, when the middleware of the first terminal sends data to the Kafka platform, the interface for sending data can be called to establish connection with the Kafka platform. The interface for transmitting data may be encapsulated in the jar packet of the above-mentioned "Mta _ kafkatkasdk" named "Mta _ kafkclientsend". The middleware of the first terminal can also receive data from the Kafka platform, when the middleware of the first terminal receives the data from the Kafka platform, the middleware of the first terminal can call an interface for receiving the data to establish connection with the Kafka platform, and the interface for receiving the data can be encapsulated in the jar packet of the Mta _ Kafka SdkClientReceive named as Mta _ kafk. Further, the first terminal is connected to the Kafka platform in the jar packet of "mta _ kafkaSdk".
The data to be sent may be data generated by the first terminal, or may also be data sent by a third terminal electrically connected to the first terminal, and for convenience, an example may be performed by using the data generated by the first terminal.
In a possible embodiment, the information carried by the data is mainly related to the scenario to which the method is applied, for example, the method may be applied in a monitoring system, and then the data to be sent may be an alarm message, for example, indicating fire alarm information, water alarm information, or theft alarm information. For example, when the application layer of the first terminal detects a trigger event, data corresponding to the trigger event may be generated according to a pre-stored data generation protocol, where a header of the data may have a character string indicating type information of the data. After the application layer of the first terminal generates data, the data may be sent to the middleware, and the data obtained by the middleware from the application layer is the data to be sent.
In step 102, the data transmitting end adds data to be transmitted to a transmission queue.
The queue length of the transmission queue may have a length threshold or may not have a length threshold, and is an infinite queue.
For example, if the data processing capacity of the data receiving end is large, for example, the data receiving end is a server, the length of the sending queue may not be limited, such as an infinite queue. Because the data processing capacity of the data receiving end is very large, for example, the data processing speed of the data receiving end is much higher than the data generating speed of a single data sending end, and thus, excessive data cannot be retained in the sending queue of each data sending end.
For another example, if the data processing capacity of the data receiving end is limited and the storage space of the data transmitting end is limited, the queue length of the transmission queue may have a length threshold. Correspondingly, the data sending end judges the relation between the current length of the sending queue and a preset length threshold value, and if the current length of the sending queue is smaller than the preset length threshold value, the data to be sent is added into the sending queue; and if the data sending end judges that the current length of the sending queue is equal to the preset length threshold, releasing the data to be sent. For example, if the middleware of the first terminal determines that the current length of the transmission queue is equal to the preset length threshold, the data to be transmitted is released, and the information that the transmission queue is full is fed back to the application layer of the first terminal, and after receiving the feedback information, the application layer may generate the data again and transmit the data to the middleware until the middleware adds the data to the transmission queue. Therefore, the preset length threshold of the transmission queue can be determined according to the storage space of the data transmitting end and the data processing capacity of the data receiving end.
In step 103, when the preset sending period is reached, the data sending end selects data not greater than the first preset amount from the sending queue according to the adding time sequence, and sends the data to the data receiving end.
The preset sending period and the first preset number are determined by technicians according to the processing capacity of the data receiving end, and can be determined by multiple tests and theoretical calculation according to the processing capacity of a server of the Kafka platform, for example, and the preset sending period and the first preset number are used for preventing a large amount of data from flooding into the data receiving end to cause downtime of the data receiving end.
In this way, when the preset sending period is reached, the middleware of the first terminal may select, in the sending queue, data not greater than the first preset number in the adding time sequence, for example, select 10 data from the sending queue, and send the 10 data to the server.
Based on the above, after the first terminal obtains the data to be sent, the data to be sent is added to the sending queue, and then the data not greater than the first preset number is periodically selected from the sending queue according to the adding time sequence and sent to the server. In this way, even if a plurality of first terminals transmit data to the server at the same time and each first terminal transmits at least one piece of data, each first terminal periodically selects data not greater than a first preset number in the transmission queue according to the adding time sequence and transmits the data to the server. Furthermore, the server can be prevented from suddenly receiving a large amount of data, so that the downtime of the server is avoided, and the normal operation of the server is ensured.
In one possible implementation, where the server is a server of a Kafka platform, the Kafka platform is an open source streaming platform that can receive any data without verifying the type information, content information, and the like of the data. That is, as long as the terminal is connected to the Kafka platform, any data can be sent to the Kafka platform, in this case, the server will likely receive data to which the terminal does not subscribe, that is, no terminal will obtain the data from the server, and the data may be referred to as useless data, and then the useless data will affect the amount of useful data sent from the first terminal to the server, where the useful data is data to which the terminal subscribes, and such data is stored in the server and is pulled by the terminal from the server.
In order to solve the above problem, after the data sending end obtains the data to be sent, the data sending end may verify the type information of the data, and correspondingly, if the data sending end detects that the type information of the data to be sent matches with the type information stored in advance, the data to be sent is added to the sending queue.
The pre-stored type information can be stored in the data sending end in the form of a form, and the form can list various types of information, for example, the method is applied to a monitoring system, and the form can have type information representing fire alarm, theft alarm, water alarm and the like.
In a possible implementation, since the application layer of the first terminal stores the character string carrying the type information in the header of the data when generating the data, the middleware of the first terminal can extract the character string representing the type information from the data to be transmitted after acquiring the data to be transmitted. If the extracted string matches one of several pre-stored strings, the data may be added to the transmit queue. If the character string extracted by the middleware from the header of the data to be transmitted is not among several character strings stored in advance, the middleware can release the data corresponding to the character string.
Therefore, the first terminal verifies the type information of the data before sending the data to the server, and the data of which the type information is not matched with the pre-stored type information can be filtered out, so that the quantity of the data sent to the server by the first terminal can be reduced. The data type information is verified, and the data carrying the virus information can be prevented from being sent to the server to damage the server. This is because the attack terminal that sends the virus information does not know the type information of the data to be sent, and therefore the type information of the data generated by the attack terminal cannot be matched with the type information that is stored in advance with a high probability, and further, the middleware of the first terminal can filter the data of the type information, and further, the server can be protected.
Optionally, in order to avoid that the data sending end sends data whose content is empty to the outside, the corresponding processing may be that the data sending end detects that the type information of the data to be sent matches with the pre-stored type information, and the data to be sent is not empty, and then the data to be sent is added to the sending queue.
In a possible implementation, the data sending end verifies the content of the data, which may be to verify whether a message of the data is empty, for example, after the middleware of the first terminal obtains the data to be sent, a character string may be first extracted from a header of the data to be sent, if the character string is one of several character strings stored in advance, then, whether the message of the data is empty is verified, and if the character string is not empty, the data is added to the sending queue. Therefore, the data sending end firstly verifies the type information of the data once, and then verifies the content of the data once on the basis that the type information meets the requirement, so that the data with the type information not meeting the requirement, the data with the type information meeting the requirement but with empty content and the data with the type information not meeting the requirement and with empty content can be completely filtered, and the data can be useless data, thereby being beneficial to preventing a data receiving end from receiving and processing the useless data.
Optionally, if the length of the data to be sent is too long, a situation of data loss is easily caused in the sending process, and in order to avoid the situation, corresponding processing may be to verify the length of the original data after the data sending end obtains the data (which is not marked as the original data), and if the data amount of the original data is greater than a preset threshold, segment the original data to obtain a plurality of data to be sent; and if the data quantity of the original data is not larger than a preset threshold value, determining the original data as the data to be sent.
In a possible implementation process, after acquiring original data, a middleware of a first terminal verifies the length of the original data, if the data amount of the original data is greater than a preset threshold, information that the data amount of the original data is greater than the preset threshold is fed back to an application layer, after receiving the feedback information, the application layer segments the original data to obtain a plurality of data and sends the plurality of data to the middleware, and after the middleware obtains a plurality of data to be sent, the plurality of data to be sent are added to a sending queue. And if the middleware detects that the data volume of the original data is not larger than a preset threshold value, directly determining the original data as the data to be sent and adding the data to a sending queue.
In a possible application, the process related to sending data may be performed by using the method, specifically, after a data sending end acquires data to be sent, the type information of the data may be verified first, if the type information of the data matches with pre-stored type information, it is further verified whether the content of the data is empty, if the content of the data is not empty, the length of the data is further verified, and if the length of the data is not greater than a preset threshold, the data is added to a sending queue, where the verification may not be limited by timing sequence. And then, when the preset sending period is reached, selecting data with the quantity not more than the first preset quantity in the sending queue according to the adding time sequence, and sending the data to a data receiving end. Therefore, the data sending end filters out the data which do not meet the requirements through layer-by-layer verification on one hand, and controls the time and the quantity of the data sent to the data receiving end on the other hand, so that the data receiving end can be prevented from receiving and processing a large amount of data in a short time, and the condition that the data receiving end is down because a large amount of data needs to be processed can be effectively prevented.
The above is the process of transmitting data, and the following will describe the process of receiving data, and the relationship between the two processes is different according to different situations:
in one embodiment, the data receiving end of the sending method is a data sending end of the receiving method, for example, the data sending end of the sending method is a first terminal, the data receiving end is a server, the data receiving end of the receiving method is a second terminal, and the data sending end is a server of the sending method. In this case, the data transmission method may be applied to a data transmission system including a first terminal, a server and a second terminal, wherein the server serves as a data receiving end to receive data from the first terminal during data transmission, and serves as a data transmitting end to transmit data to the second terminal during data reception. The process of the first terminal transmitting data to the server is performed according to the above-described method of transmitting data, and the process of the second terminal receiving data from the server may be performed according to a method of receiving data, which will be described below.
Alternatively, the executing body of the sending method and the executing body of the receiving method may be the same, and both are the first terminal, and when the first terminal sends data to the server, the first terminal may also receive data from the server, and when receiving data from the server, the first terminal may execute the method described below.
In other cases, the execution bodies of the sending method and the receiving method may correspond to each other, that is, the data sending end of the sending method is also the data sending end of the receiving method, and the data receiving end of the sending method is also the data receiving end of the receiving method. That is, the data sending end of the sending method is the first terminal, and the data receiving end is the server; the data receiving end of the receiving method is also a server, and the data sending end is also a first terminal. The procedure of the above-described transmission method is described from the perspective of a station at a first terminal, and the procedure of the reception method to be described below may be described from the perspective of a station at a server.
In the following, the second terminal will be used to receive data from the server, and other cases are similar to the above case and will not be described in detail.
As shown in fig. 2, the flow of the second terminal receiving data from the server is schematically shown as follows:
in step 201, the data receiving end receives data to be processed.
Step 201 may be performed immediately after step 103, or at any time after step 103, which is mainly related to the application scenario of the method. For example, if the method is applied in an instant messaging application, such as in a monitoring system, step 201 is performed immediately after step 103. For another example, if the data receiving end performs periodic or random statistics on the received data, step 201 may be performed at any time after step 103.
In a possible implementation, the main body specifically performing the reception of the data to be processed may also be a middleware integrated on the second terminal, the middleware uses a program for receiving the data in transmitting the data, and accordingly, the middleware of the second terminal may receive the data to be processed from the server.
When the middleware of the second terminal needs to receive data, for example, when the middleware of the second terminal receives data from the Kafka platform, the interface for receiving data may be called to establish a connection with the Kafka platform, as described above, the interface for receiving data may be encapsulated in the jar packet of "Mta _ Kafka sdk client receive" by naming "Mta _ Kafka sdk", and the first terminal is connected with the Kafka platform in the jar packet of "Mta _ Kafka sdk".
In a possible implementation process, the second terminal may receive the data to be processed from the server in a manner that, when a preset receiving period is reached, the middleware of the second terminal sends a request for obtaining the data to the server; and if the data to be processed exists in the server, sending the data to be processed to the middleware of the second terminal, and further receiving the data to be processed by the middleware of the second terminal. The second terminal may receive the data to be processed from the server in a manner that, after the second terminal establishes a connection with the server, the server may periodically push the data to the second terminal.
In step 202, the data receiving end adds the data to be processed to the processing queue.
In a possible embodiment, in order to avoid that the application layer of the second terminal suddenly receives and processes a large amount of data, the middleware of the second terminal adds the data to be processed to the processing queue after receiving the data to be processed, accordingly.
In step 203, when the preset selection period is reached, the data receiving end selects data not greater than the second preset amount in the processing queue according to the adding time sequence for processing.
The preset selection period and the second preset number can be determined through multiple tests and theoretical calculation according to the data processing capacity of the data receiving end.
In a possible embodiment, when the preset selection period is reached, the middleware of the second terminal selects data not greater than a second preset number from the processing queue according to the adding time sequence, and sends the data to the application layer for processing. Therefore, the situation that the second terminal goes down due to the fact that the application layer of the second terminal needs to process a large amount of data suddenly can be avoided, and normal operation of the second terminal is guaranteed.
When the middleware sends data to the application layer, the middleware can call a callback interface to establish connection with the application layer, and the callback interface can be encapsulated in Mta _ kafkaSdkClient _ CallBackInterface in a named mode.
If the method is applied to a monitoring system, the application layer of the second terminal can be an alarm, and if the data to be processed is fire alarm information, the application layer can send out an alarm signal corresponding to the fire alarm information.
Optionally, if the processing capability of the second terminal is relatively strong, the length of the processing queue may not be limited, for example, the processing queue may be an infinite queue. And if the processing capacity of the second terminal is limited, correspondingly, when the preset receiving period is reached, if the current length of the processing queue is smaller than the preset length threshold, the middleware of the second terminal sends a data acquisition request to the server.
In a possible embodiment, when the preset receiving period is reached, the middleware of the second terminal first detects the current length of the processing queue, and if the current length of the processing queue is smaller than a preset length threshold, the middleware sends a request for obtaining data to the server. And if the current length of the processing queue is equal to the preset length threshold value, the middleware stops sending the data acquisition request to the server, so that a large amount of data can be prevented from being blocked in the processing queue.
Based on the above, the process of the second terminal receiving the data from the server may be that, when the preset receiving period is reached, the middleware of the second terminal sends a request for obtaining the data to the server, where the request may carry type information of the data, and after the server receives the request, if there is data of the type information carried in the request, the server sends the data to the second terminal. And the middleware of the second terminal receives the data sent by the server as the data to be processed, the data to be processed is added into the processing queue, when the preset selection period is reached, the middleware selects the data not more than a second preset number in the processing queue according to the adding time sequence and sends the data to the application layer, and the application layer processes the data after receiving the data. Therefore, the second terminal periodically selects a second preset amount of data for processing, and the second terminal can be prevented from being down due to the fact that a large amount of data are processed in a short time.
In a possible application, the process related to receiving data may be performed by using the method described above, specifically, after the data receiving end receives the data to be processed, the data to be processed is first added to the processing queue, and then the data not greater than the second preset number is periodically selected from the processing queue according to the adding time sequence for processing. Therefore, the data receiving end can be prevented from being crashed due to the fact that a large amount of data are suddenly processed by the data receiving end, and normal operation of the data receiving end is guaranteed.
In the embodiment of the present disclosure, when the data sending end uses the above method to transmit data to the data receiving end, after the data to be sent is obtained, the data to be sent is added to the sending queue, and then the data not greater than the first preset number is periodically selected from the sending queue according to the adding time sequence and sent to the data receiving end. Therefore, by controlling the period of sending data to the data receiving end and the quantity of the data sent each time, the data receiving end can be effectively prevented from suddenly receiving a large amount of data, so that the condition that the data receiving end goes down due to the fact that the data receiving end processes a large amount of data is avoided, and the normal operation of the data receiving end is guaranteed.
Based on the same technical concept, an embodiment of the present disclosure further provides a device for transmitting data, where the device may be a data transmitting end in the foregoing embodiment, that is, the first terminal, as shown in fig. 3, and the device includes:
