Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flowchart of a data transmission method according to an embodiment of the present application. The data transmission method is applied to data publishing equipment, the data publishing equipment is connected with proxy subscribing equipment, the proxy subscribing equipment is connected with user receiving equipment, and the data transmission method comprises the following steps:
step S101, determining a data acquisition mode of each agent subscription device, wherein the data acquisition mode comprises any one of active acquisition and passive push.
The data publishing device broadcasts the subject address of the publishing source data subject so that the proxy subscribing device listens whether the subject address generates new source data. And if the topic address generates new source data, the corresponding source data topic is indicated to be updated, and after the data acquisition mode corresponding to each agent subscription device is determined, the new source data is sent to each agent subscription device according to the corresponding data acquisition mode.
In specific implementation, different proxy subscription devices may be associated with different data acquisition manners according to user input, and a specific association relationship example is shown in table 1:
TABLE 1
Table 1 is a correspondence table between the device number and the data acquisition code. In particular, different proxy subscribing devices, such as #0001 and #0002, can be represented by device numbers. Different data acquisition modes can also be represented by different data acquisition codes, wherein 0 can be defined as passive push and 1 can be defined as active acquisition. The specific form of the data acquisition code and the corresponding relationship between different data acquisition codes and data acquisition modes can be customized according to the use requirement of the user and the specific application scene, and are not further limited here.
Step S102, if the data acquisition mode of the agent subscription device is active acquisition and a data acquisition instruction sent by the agent subscription device is received, performing authorization verification based on an authorization verification mechanism associated with the agent subscription device and the data acquisition instruction, wherein the agent subscription device sends the data acquisition instruction to the data publishing device when monitoring that a source data topic in a topic address broadcasted by the data publishing device is updated.
For any agent subscription device, if the data acquisition mode of the agent subscription device is active acquisition and the agent subscription device monitors that the topic address broadcasted by the data publishing device generates new source data, the agent subscription device sends a data acquisition instruction to the data publishing device. If the data publishing device receives the data acquisition instruction sent by the proxy subscribing device, the data publishing device can perform authorization verification based on an authorization verification mechanism associated with the proxy subscribing device and the data acquisition instruction, so that new source data is sent to the proxy subscribing device passing the authorization verification, and the security of data transmission is ensured.
Specifically, the authorization verification mechanism includes different first-type preset rules, each of the different first-type preset rules includes different second-type determination data, where the different first-type preset rules include an allowance rule and a rejection rule, and the different second-type determination data includes a preset authorization time interval, a preset IP address corresponding to the proxy subscription device, and a preset control ID corresponding to a target application running on the proxy subscription device;
the generation step of the authorization verification mechanism comprises the following steps:
receiving the judgment data sent by the proxy subscription equipment;
combining different judgment data into preset rules according to a selection instruction input by a user, wherein the corresponding second types in the preset rules with the same judgment data quantity are different in composition;
and arranging all the preset rules into the authorization verification mechanism according to a sequencing instruction input by a user.
Different authorization verification mechanisms may be associated with each proxy subscribing device based on user input. Referring to fig. 2, fig. 2 is a schematic diagram illustrating an authorization verification mechanism involved in a data transmission method according to an embodiment of the present application. Any authorization verification mechanism includes at least two preset rules and the first type of the two preset rules is different. Wherein the different first type of preset rules comprise an allow rule and a deny rule. For example, the line structure S1 with rule number a and the line structure S2 with rule number B are both used to represent a preset rule. The type number 1 or 0 corresponding to the preset rule in each line structure is used to indicate the type of the preset rule, for example, 1 may be used to indicate an allowance rule, and 0 may be used to indicate a denial rule; 0 may be used to indicate an allow rule and 1 may be used to indicate a deny rule.
In addition, a character string with a specific structure may be used to simultaneously indicate the rule number and the type of the preset rule corresponding to the rule number, for example, a0 and B1 are respectively used to indicate two different types of preset rules. The specific corresponding relationship can be customized according to the actual use requirement of the user and the specific application scene, and is not further limited here.
The different first type of preset rules comprise different second type of judgment data, and the different second type of judgment data comprise but are limited to a preset authorization time interval, a preset IP address corresponding to the proxy subscription device, and a preset control ID corresponding to a target application running on the proxy subscription device. Different second types and different amounts of decision data are combined through user input, and preset rules of different first types can be obtained. For example:
1. if the user's settings are: any proxy subscription device which communicates with the data publishing device through the preset IP address of 10.255.255.255 can receive newly generated source data in the source data topic. Then the permission rule corresponding to the user setting may be set to "A10.255.255.2551";
2. if the user's settings are: if the proxy subscribing device communicates with the data publishing device through the preset IP address "10.255.255.255" and the preset control ID corresponding to the target application running on the proxy subscribing device is 8888, the proxy subscribing device may receive newly generated source data in the source data topic. Then the permission rule corresponding to the user setting may be set to "B10.255.255.25588881".
In specific implementation, the second type of determination data may also be an account, a password, or the like, and the second type of determination data may be customized according to an actual use requirement of a user or a specific application scenario, which is not further limited herein.
In specific implementation, each data acquisition instruction comprises a request time, a real-time IP address corresponding to the proxy subscription device, and a real-time control ID corresponding to a target application running on the proxy subscription device;
the step of performing authorization verification based on the authorization verification mechanism associated with the proxy subscription device and the data acquisition instruction includes:
selecting a preset rule corresponding to the first order as a target rule according to the arrangement sequence of each preset rule in the authorization verification mechanism;
repeatedly executing the step of judging whether the data acquisition instruction is matched with the target rule or not until all the preset rules are matched;
if the data acquisition instruction is matched with the target rule, judging whether the target rule is an allowable rule or not;
if the target rule is an allowable rule, judging that the authorization verification is passed;
and if the target rule is a rejection rule, judging that the authorization verification fails.
Different first type of preset rules may be set with different priorities for execution or determination. For example, the preset rule a is an allowance rule, and the preset rule B is a denial rule. If the priority of the preset rule a is greater than that of the preset rule B, the preset rule a may be arranged before the preset rule B when the authorization verification mechanism is generated. That is, only when the data acquisition instruction sent by the proxy subscription device does not match all the determination data included in the preset rule a, the determination on the preset rule B is continued. The following is illustrated by way of an example:
the authorization verification mechanism comprises a preset rule A and a preset rule B. The preset rule a is used to indicate that: any one of the proxy subscribing devices communicates with the data publishing device through a preset IP address "10.255.255.255", and if a preset control ID corresponding to a target application running on the proxy subscribing device is 8888, the proxy subscribing device can receive newly generated source data in a source data topic; the preset rule B is used to indicate that: if the preset control ID corresponding to the target application running on the proxy subscription device is not 8888, the proxy subscription device may not receive the newly generated source data in the source data topic. In the corresponding authorization verification mechanism, the preset rule A is arranged before the preset rule B.
If the data acquisition instruction is 12: 0010.255.255.2558800, according to the arrangement sequence of the preset rules in the authorization verification mechanism, selecting the preset rule A corresponding to the first sequence as a target rule, and executing the step of judging whether the data acquisition instruction is matched with the target rule or not. At this time, the preset rule B corresponding to the next sequence is updated to be the target rule, and the step of judging whether the data acquisition instruction is matched with the target rule is executed. The data acquisition instruction matches the determination data in the preset rule B for indicating that "the preset control ID is not 8888". And judging that the verification fails because the preset rule B is a rejection rule.
Through the technical means, the arrangement sequence of the preset rules in the authorization verification mechanism corresponding to each agent subscription device can be adjusted to realize the safety verification of different levels, and the reusability and the adjustable flexibility of the authorization verification mechanism are high.
Step S103, if the authorization verification is passed or the data acquisition mode of the proxy subscription device is passive pushing, incremental data corresponding to a source data theme is sent to the proxy subscription device, so that the proxy subscription device converts the incremental data into service data and sends the service data to the user receiving device.
The incremental data is the source data generated in the subject address. And if the data acquisition mode of the proxy subscription equipment is passive pushing or the data acquisition mode of the proxy subscription equipment is active acquisition and the authorization verification is passed, sending the incremental data corresponding to the source data theme to the proxy subscription equipment. The proxy subscription device may convert the incremental data into service data that the user receiving device may directly receive or process, and then send the service data to the user receiving device.
According to the data transmission method, when the data acquisition mode of the proxy subscription device is active acquisition and a data acquisition instruction sent by the proxy subscription device is received, authorization verification is performed based on an authorization verification mechanism associated with the proxy subscription device and the data acquisition instruction. If the authorization verification is passed or the data acquisition mode of the proxy subscription equipment is passive pushing, incremental data corresponding to the source data theme are sent to the proxy subscription equipment, so that the proxy subscription equipment converts the incremental data into service data and sends the service data to the user receiving equipment. By the authorization verification mechanism, the incremental data corresponding to the source data theme can be safely sent to the proxy subscription equipment which establishes the subscription relationship. Moreover, by adjusting the arrangement sequence of each preset rule in the authorization verification mechanism corresponding to each proxy subscription device, the security verification of different levels can be realized, and the reusability and adjustable flexibility of the authorization verification mechanism are improved.
