Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some but not all of the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection. It should be noted that the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict.
When software on a server is tested, real traffic of an online server is generally copied to a test server by using a tcp copy, and the software is sufficiently tested by simulating the real traffic, but in reality, a client request includes an http request and an http request, and the http request is a stateless request, so the tcp copy can smoothly copy traffic of the http request to the test server, but for the http request, the traffic of the http request cannot be simply copied to the test server due to the use of an encryption technology.
A traffic copying method is provided herein, fig. 1 is a flowchart of the traffic copying method applied to an online server, and referring to fig. 1, the traffic copying method applied to the online server includes:
step S11, receiving a client request;
step S12, copying the client request to the offline server;
step S13, sending online server information for decrypting the client request to an offline server, so that the offline server decrypts the client request; or receiving an offline server random number sent by an offline server, and generating a second secret key based on the offline server random number; wherein the client request comprises an HTTPS request.
The request of the client can be an HTTP request or an HTTPS request, and the client request is copied to the offline server after the online server receives the client request. In response to the HTTP request, the offline server can respond directly to the HTTP request due to the characteristics of HTTP itself. For the HTTPS request, the HTTPS protocol is used, and is constructed by SSL + HTTP protocol, and the data transmission thereof is encrypted data. The encryption mode is agreed by both the client and the server, and the key for encryption is generated based on the random number of the client and the random number of the online server, so that even if the offline server uses the same certificate as the online server and has the same configuration, the random number of the server is different, and the random number of the offline server and the random number of the client generate the key different from that of the online server, so that the traffic data copied by the online server cannot be decrypted. Thus, in the method described herein, in order for the online server and the offline server to be able to decrypt the same HTTPS request, the relevant settings and operations need to be performed, the online server and the offline server use the same server random number line, or use the same key, and therefore the online server also needs to send online server information for decrypting the client request to the offline server so that the offline server can decrypt the client request. Or receiving an offline server random number sent by the offline server, and generating a second secret key based on the offline server random number.
The online server information comprises an online server random number or a first secret key generated after handshaking with the client, and the sending of the online server information used for decrypting the client request to the offline server comprises the following steps:
sending an on-line server random number generated in a handshake process with a client to an off-line server;
or sending a first secret key generated after handshaking with the client to the offline server.
In order to enable the offline server to decrypt the encrypted request of the client, the online server may send its own server random number to the offline server in a handshake with the client, and the offline server may generate a key based on the online server random number and the client random number to decrypt the client request.
Alternatively, the online server may send the generated first secret key to the offline server after handshaking with the client, and the offline server may decrypt the client request using the first secret key.
Similarly, the online server may also generate a second secret key based on the offline server random number, including: and replacing the random number of the online server with the random number of the offline server, and generating a second secret key based on the random number of the offline server and the random number of the client. The offline server also generates a secret key identical to the second secret key based on the random number of the offline server and the random number of the client, so that the HTTPS request sent by the client to the online server and encrypted by using the second secret key can be decrypted.
Fig. 2 is a flowchart of a traffic copy method applied to an offline server, and referring to fig. 2, the traffic copy method includes:
step S21, receiving a client request copied by the online server, wherein the client request comprises an HTTPS request;
step S22, sending the offline server random number to the online server, and generating a third key based on the offline server random number and the client random number. Or receiving online server information sent by the online server.
Step S23, when the client request is an HTTPS request, decrypting the HTTPS request using the third secret key; or based on the online server information, the HTTPS request is decrypted.
After receiving the client request copied by the online server, the offline server sends a random number of the offline server to the online server, so that the online server generates a second secret key based on the offline server random number and the client random number, and simultaneously, the online server generates a third secret key based on the offline server random number and the client random number.
Or, the offline server receives the online server information sent by the online server while receiving the client request copied by the online server, and the offline server can decrypt the HTTPS request in the client traffic copied by the online server.
The online server information is an online server random number or a first secret key generated after handshaking between the online server and the client, and the decrypting the HTTPS request comprises the following steps of:
when the online server information is an online server random number, generating a fourth secret key based on the online server random number, and decrypting the HTTPS request of the client by using the fourth secret key;
and when the online server information is the first key, decrypting the HTTPS request of the client by using the first key.
Generating the fourth key based on the online server random number includes:
and replacing the random number of the offline server with the random number of the online server, and generating a fourth secret key based on the random number of the online server and the random number of the client.
Likewise, the first key and the fourth key are also generated based on the same random number, and thus the first key and the fourth key are identical, enabling the offline server to decrypt the HTTPS request copied by the online server.
If the online server information sent by the online server is the first key, the traffic server may respond to the request of the client based on the random number of the traffic server after receiving the handshake request of the client, but in the stage of generating the key, the first key is used as the generated key, or replaces the generated key, to decrypt the HTTPS traffic of the client.
By the method, in the process of copying the flow of the online server, the HTTP flow and the HTTPS flow do not need to be distinguished, and the information of the online server is sent to the test server, so that the test server can decrypt the HTTPS flow smoothly, and the purpose of truly simulating the online flow is achieved.
