In order to maintain that a background server is not exposed, in the related art, a proxy node is adopted for data transparent transmission, a client sends a request message to the proxy node, the proxy node is connected with the server and forwards the request message to the server, after the server completes a corresponding task according to the request message, response information is fed back to the proxy node, the proxy node forwards a feedback response to the client, and communication between the client and the server is completed. Based on the technical problem, the present embodiment provides a data transparent transmission method, in this embodiment, a client determines a plurality of target proxy nodes according to node attribute information of the proxy nodes, the node attribute information of the proxy nodes at different times is different, then the plurality of target proxy nodes send a request message to a server, the server determines a response message according to the request message, the server sends the response message to the plurality of target proxy nodes, the target proxy nodes forward to the client, at this time, the target proxy node received by the client first is taken as an assigned proxy node, and the client receives the response message sent by the assigned proxy node; therefore, a plurality of target proxy nodes determined at each moment may be different, and therefore, the addresses of the proxy nodes are not regularly circulated and are not easily exposed, so that the possibility of being attacked is greatly reduced, and the stability and reliability of data transmission are improved, specifically referring to fig. 1, where fig. 1 is a flowchart of a data transparent transmission method provided in an embodiment of the present application, specifically including:
s101, determining a plurality of target agent nodes according to the node attribute information of all the agent nodes.
The embodiment is mainly applied to the client, the client corresponds to a plurality of proxy nodes, the number of the proxy nodes is not limited in the embodiment, and a user can set the proxy nodes by himself/herself. It can be understood that the agent nodes can be communicated with each other, the communication process, i.e., the networking process, can be performed by a certain agent node, and after the networking is successful, the agent nodes maintain the connection by sending heartbeat packets to each other. The node attribute information includes but is not limited to response speed, historical transparent transmission information and transmission success rate; the determining mode of the response speed can be that the client sends a response signal to the proxy node, the sending time is recorded, the proxy node sends a feedback signal to the client after receiving the response signal, the receiving time of the client is recorded, and the client determines the response speed according to the difference value between the sending time and the receiving time; the historical transparent transmission information comprises historical record information of realizing transparent transmission of the agent node, and comprises information of successful transparent transmission and failure of transparent transmission.
The number of target agent nodes in this embodiment includes, but is not limited to, 2, 3, and 4.
S102, the request message is sent to a plurality of target agent nodes, so that the plurality of target agent nodes can forward the request message to a server.
And the client sends the request message to a plurality of target agent nodes, wherein when the number of the target agent nodes is multiple, the client sends the request message to all the target agent nodes in a concurrent manner. And after receiving the request message, the target agent node forwards the request message to a server through an http transparent transmission technology. Because the request message of the client is sent to the plurality of target agent nodes in a concurrent manner, even if a certain target agent node is attacked and stops service, the requests of other target agent nodes still have the opportunity to be forwarded to the server, so that the stability and reliability of the service are ensured, and meanwhile, because the plurality of target agent nodes are mutually backed up and redundant, the fastest target agent node can be found and forwarded to the server, so that the high quality of the service can be ensured. In an implementation manner, when the number of the target proxy nodes is at least two, after all the target proxy nodes receive the request message, all the target proxy nodes forward the request message to the server.
S103, receiving a response message which is determined by the server and forwarded by the appointed proxy node according to the request message, wherein the appointed proxy node is a target proxy node corresponding to the received first response message.
It can be understood that, after the server receives the request messages forwarded by the plurality of target proxy nodes, the server determines corresponding response messages according to the request messages. The server sends the response message to the corresponding target agent nodes, all the target agent nodes forward the response message to the client, at the moment, the target agent nodes complete the transparent transmission function, and after the client receives the first response message sent by the appointed agent node, the client does not receive the response messages sent by other target agent nodes. It can be seen that the present embodiment scatters the agent nodes, and when one or some of the agent nodes stop service due to an attack, other target agent nodes can quickly replace the availability of the maintenance service. The whole process well protects the background server from being exposed, so that the background server is prevented from being attacked by hackers. In this embodiment, there is no centralized server, and the target agent nodes used by the user to access the server each time may be different, so that even if some transparent transmission machines, that is, the target agent nodes are attacked, the system may still select other target agent nodes for transparent transmission, and when other target agent nodes are attacked, the original machine may have recovered service, thereby making the service more robust.
Based on the above technical solution, in this embodiment, the client determines a plurality of target proxy nodes according to node attribute information of the proxy nodes, the node attribute information of the proxy nodes at different times is different, then the plurality of target proxy nodes send the request packet to the server, the server determines a response packet according to the request packet, the server sends the response packet to the plurality of target proxy nodes, and the target proxy nodes forward to the client, at this time, the target proxy node received first by the client is taken as a designated proxy node, and the client receives the response packet sent by the designated proxy node; therefore, the plurality of target proxy nodes determined at each moment are different, so that the addresses of the proxy nodes are not regular and can not be exposed easily, the possibility of being attacked is greatly reduced, and the stability and the reliability of data transmission are improved.
As further elaborated with respect to step S101, determining a plurality of target proxy nodes according to the node attribute information of all the proxy nodes includes: detecting the response speed of all the agent nodes every other preset period, and establishing a routing table of the agent nodes and the response speed;
and determining a plurality of target proxy nodes according to the response speed of the proxy nodes in the routing table within the time range of the preset period.
The determining method of the response speed may be that the client sends a response signal to the proxy node, records the sending time, sends a feedback signal to the client after the proxy node receives the response signal, records the receiving time of the client, and determines the response speed according to a difference between the sending time and the receiving time. The target proxy node with high transmission rate can be determined according to the response speed, and the data transmission efficiency is improved.
In this embodiment, the response speeds of all the proxy nodes are detected every preset period, the response speeds and the IDs of the corresponding proxy nodes are recorded, and a routing table of the proxy nodes and the response speeds is established, where the routing information in the routing table includes, but is not limited to, path information and response speeds, and may also include other information, which is not limited in this embodiment, and the user may set the routing table by user-definition. At this time, in a time range corresponding to the preset period, that is, in a time range between two detection response speeds, the target proxy node is determined according to the corresponding speed of the proxy node in the routing table. It can be understood that, when the preset period is shorter, the frequency of detecting the response speed is increased, the real-time performance of the obtained response speed is higher, and when a certain proxy node goes offline or connection fails due to network fluctuation, it may be determined that all new target proxy nodes complete the data transparent transmission function, so as to provide an uninterrupted transparent transmission service for the whole data transmission, and improve the reliability and stability of data processing.
As further elaborated with respect to step S101, determining a plurality of target proxy nodes according to the node attribute information of all the proxy nodes includes: and determining a plurality of target agent nodes according to the historical transparent transmission information of all the agent nodes.
The historical transparent transmission information comprises historical record information of realizing transparent transmission of the agent node, and comprises information of successful transparent transmission and failure of transparent transmission. And determining that the transparent transmission is successful according to the historical transparent transmission information, and taking the proxy node with the transparent transmission success rate larger than the preset threshold value as a target proxy node to obtain a plurality of target proxy nodes, so that the connection between the target proxy node and the server can be successfully established, the occurrence of connection failure is avoided, the connection success rate of the proxy node and the server is improved, and the reliability and the stability of data transmission are further ensured.
Before step S101, the method may further include: and acquiring request data, and packaging and encrypting the request data to obtain a request message.
The request message is an encrypted message, so that when the proxy node stops service due to attack, the content of the request message cannot be acquired because the request data is encrypted data, and the risk of data leakage is reduced. Meanwhile, because the request data is encrypted, the characteristics of the data packet cannot be analyzed through packet capturing, and the transmitted data content cannot be determined, so that the service node is ensured not to be exposed through the node consistency.
In an implementation mode, when the target agent nodes are three target agent nodes, the client packages and encrypts the request data to obtain a request message, the client sends the request message to the three target agent nodes in parallel, after the three target agent nodes receive the request message, the three target agent nodes forward the request message to the server, in the process, if one target agent node stops service, the data transmission of other target agent nodes cannot be influenced, other target agent nodes forward the request message to the server, the reliability of the data transmission is ensured, and due to the fact that the target agent nodes are multiple target agent nodes, and the target agent nodes are constantly changing and are not fixed, the redundant forwarding technology of the multiple target agent nodes is adopted, so node information cannot be exposed, the reliability and the safety of data transmission are ensured.
After step S103, the method may further include: the connection with all the target agent nodes is disconnected. In an implementation manner, if the server sends the response packet to all the target proxy nodes, after one of the target proxy nodes successfully forwards the response packet to the client, the client disconnects from all the target proxy nodes, and it is ensured that the response packet is not repeatedly received.
