Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a data processing method provided by an embodiment of the present invention, and the data processing method of the present embodiment is applied to a server. As shown in fig. 1, the data processing method includes the steps of:
The access request may be a download request or an access request to a web page. The terminal can send an access request to the server through the client to download the target file or access a webpage corresponding to the target file.
After receiving the access request, the server may search for the target file in the stored resource pool, and obtain a target data stream corresponding to the target file. Wherein the target data stream is a data stream comprising a preset target feature code and a source file. The target signature may be located at the head, tail, or other portion of the target data stream. Preferably, the target feature code may be provided at the head of the target data stream for easy reading of the target feature code. Therefore, the terminal can read the feature code first, verify the feature code and then read the data of the target file behind the feature code, and the implementation mode is simple.
For example, an installation package is a file with a length of L, and when the file is stored in the server, the file has a length of N + L, where N is the length of the target feature code. If such a file containing the feature code is used as it is, a format error may occur and the file cannot be analyzed. Therefore, the security of the target file can be improved by adding the target feature code to the target data stream so as to prevent network hijacking.
The target feature code can also be dynamically set, namely set through a client and exchanged through interaction between the client and the server. Thus, the security of the file can be further improved.
When the step is implemented specifically, the server may send the target data stream to the terminal, so that the terminal obtains the target feature code in the target data stream and verifies the target feature code. If the verification is successful, the terminal can read the data stream of the target file, store the target file, or analyze the target file and display the target file as page information.
In addition, the server may also send the target feature code first, and send the data stream of the target file after the terminal successfully verifies the target feature code.
The terminal in the embodiment of the present invention may be a Mobile phone, a Computer, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The data processing method of the embodiment of the invention receives an access request of a terminal to a target file; acquiring a target data stream corresponding to the target file according to the access request, wherein the target data stream comprises a preset target feature code and a data stream of the target file; and sending the target data stream to the terminal so that the terminal reads the data stream of the target file after verifying the target feature code. Therefore, when the terminal acquires the data stream of the target file, network connection with the server does not need to be reestablished, and the communication speed between the terminal and the server is improved. And the target data stream contains the target feature code, so that the target file can be prevented from being hijacked.
Referring to fig. 2, fig. 2 is a flowchart of a data processing method according to an embodiment of the present invention. As shown in fig. 2, the data processing method applied to the terminal includes the following steps:
The access request may be a download request or an access request to a web page. The terminal can send an access request to the server through the client to download the target file or access a webpage corresponding to the target file.
The target data stream may include a preset target feature code and a data stream of the source file. The target signature code may be located at the head of the target data stream, or may be located at the tail or other locations. Preferably, the target feature code may be provided at the head of the target data stream for easy reading of the target feature code. Therefore, the terminal can read the feature code first, verify the feature code and then read the data of the target file behind the feature code, and the implementation mode is simple.
For example, an installation package is a file with a length of L, and when the file is stored in the server, the file has a length of N + L, where N is the length of the target feature code. If such a file containing the feature code is used as it is, a format error may occur and the file cannot be analyzed. Therefore, the security of the target file can be improved, and the phenomenon of network hijacking can be prevented. Therefore, the security of the target file can be improved by adding the target feature code to the target data stream so as to prevent network hijacking.
The target feature code can also be dynamically set, namely set through a client and exchanged through interaction between the client and the server. Thus, the security of the file can be further improved.
And 203, acquiring the target feature code and verifying the target feature code.
After the terminal acquires the target data stream, the terminal may first acquire the target feature code in the target data stream and verify the target feature code. During specific verification, whether the target feature code is the same as the preset verification code or not can be judged. If the target feature code is the same as the preset check code, the target feature code is checked successfully; and if the target feature code is different from the preset check code, the check fails.
Optionally, after the step of checking the target feature code, the method further includes: and if the target feature code is failed to be checked, discarding the data stream of the target file.
In this embodiment, if the verification of the target feature code fails, it may be determined that the target file is hijacked. At this time, the terminal may discard the data stream of the target file. Therefore, when the target file is hijacked, the data stream of the target file is not read, and the data security can be improved.
And 204, if the target feature code is successfully verified, acquiring the data stream of the target file.
After the target feature code is successfully verified, the data stream of the target file can be obtained after the target feature code is removed. For example, if the target data stream corresponding to the target file includes the N-bit signature and the data stream of the L-bit target file, the N-bit signature is located at the head of the data stream. If the verification of the N-bit feature code is successful, the data of the target file can be read from the (N + 1) -th bit, so that the data stream of the target file is obtained.
Optionally, when the access request is a download request, after the step of obtaining the data stream of the target file, the method further includes:
and storing the data stream of the target file as the target file.
In this embodiment, the terminal may obtain the data stream of the target file, and analyze the data stream of the target file, thereby obtaining the target file. Thus, the file downloading speed and the file downloading efficiency can be improved.
The terminal in the embodiment of the present invention may be a Mobile phone, a Computer, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The data processing method of the embodiment of the invention sends an access request to a target file to a server; receiving a target data stream sent by the server according to the access request, wherein the target data stream comprises a preset target feature code and a data stream of a target file; acquiring the target feature code, and checking the target feature code; and if the target feature code is successfully verified, acquiring the data stream of the target file. Therefore, when the terminal acquires the data stream of the target file, network connection with the server does not need to be reestablished, the communication speed between the terminal and the server is improved, and the loss of the server and the terminal is reduced. And the target data stream contains the target feature code, so that the target file can be prevented from being hijacked.
