Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
The Domain Name resolution method in this embodiment is based on Domain Name System (DNS) service in a Berkeley Internet Name Domain (Bind).
Fig. 1 is a flowchart of a domain name resolution method according to an embodiment of the present invention, where the method is applicable to domain name resolution, and the method may be executed by a domain name resolution device, where the domain name resolution device may be composed of hardware and/or software, and may be generally integrated in a device with a domain name resolution function, where the device may be an electronic device such as a server, a mobile terminal, or a server cluster. As shown in fig. 1, the method specifically includes the following steps:
step 110, receiving a domain name request sent by a client.
The domain name request may be a request sent by the client to access a website. In this embodiment, when a user wants to access a certain website, the link corresponding to the website is input into the search box of the client, and the client initiates a domain name request to the network card through the input link.
And step 120, distributing the domain name request to at least two analysis threads for analysis, and obtaining an analysis log.
The resolution log may include information such as an IP of the client, a request time, and a request domain name. The resolution thread may be pre-created to resolve received domain name requests. The resolution log may be generated when a domain name request is received, or the resolution thread may begin resolving the domain name request.
Specifically, when a domain name request sent by a client is received, a task corresponding to the domain name request is distributed to at least two analysis threads which are already established for analysis, and an analysis log corresponding to the analysis request is obtained.
Step 130, sending the analysis log to the created log recording thread, so that the log recording thread writes the analysis log into a log file.
The logging thread may be a thread created in advance for writing the parsing log into the log file.
Optionally, before sending the analysis log to the created log recording thread, so that the log recording thread writes the analysis log into the log file, the method further includes the following steps: acquiring the data volume which can be processed in unit time of a log recording module and the data volume which can be written in unit time of a log file; determining the number of log files according to the data volume which can be processed in the unit time of the log recording module and the data volume which can be written in the unit time of the log files; and creating a log file according to the number of the log files.
The data volume that can be processed by the logging module in unit time may be an attribute that the logging module itself has, and is determined by a configuration parameter of the logging module. The amount of data that can be written in a log file per unit time can be determined by the attributes of the log file itself. Specifically, the number of log files is obtained by dividing the data amount that can be processed in the unit time of the log recording module by the data amount that can be written in the unit time of the log files. For example, assuming that the data amount that can be processed by the logging module in unit time is Q, and the data amount that can be written in the log file in unit time is C, the number of log files can be obtained according to the following formula: and Q is n C, wherein n is the number of log files needing to be created.
Optionally, the method further comprises the following steps: acquiring the processable data volume of a single log recording thread in unit time; determining the number of the log recording threads according to the data volume which can be processed by a single log recording thread in unit time and the data volume which can be processed by a log recording module in unit time; creating the logging thread according to the number of the logging threads.
The data amount that can be processed by a single logging thread per unit time may be an attribute that the logging thread itself has. Specifically, the number of the logging threads is obtained by dividing the data amount which can be processed by the logging module in unit time by the data amount which can be processed by a single logging thread in unit time, and finally the logging threads are determined according to the determined number. For example, assuming that the data amount that can be processed by the logging module per unit time is Q, and the data amount that can be processed by a single logging thread per unit time is W, the number of logging threads may be obtained according to the following formula: q is m W, where m is the number of logging threads.
In this embodiment, the number of log files may also be preset, and then the number of log recording threads that need to be created is determined according to the number of log files. The relation between the number of the log files and the number of the log recording threads is as follows: n C W, i.e. n/m W/C.
Optionally, the sending the analysis log to the created log recording thread, so that the process of writing the analysis log into the log file by the log recording thread may be: and sending the analysis log to the created log recording thread, acquiring a log file of the current space, and controlling the log recording thread to write the analysis log into the current idle log file.
Fig. 2 is a relationship diagram of a logging thread and a log file in the present embodiment. As shown in fig. 2, the logging thread may write the parse log into any free log file. Specifically, if there are a plurality of currently idle log files, the log recording thread randomly selects one log file to write the analysis log.
Step 140, returning the analysis result output by the analysis thread to the client.
The analysis result may be data of a webpage corresponding to the domain name sent by the client. Specifically, after the domain name is analyzed by the analysis thread, an analysis result is obtained, and the analysis result is returned to the value client, so that the data in the analysis result is displayed by the client.
According to the technical scheme, firstly, a domain name request sent by a client is received, then the domain name request is distributed to at least two analysis threads for analysis, an analysis log is obtained, then the analysis log is sent to a created log recording thread, the log recording thread writes the analysis log into a log file, and finally an analysis result output by the analysis thread is returned to the client. According to the domain name resolution method provided by the embodiment of the invention, the records of the domain name resolution and the resolution log are respectively processed in two threads, so that the waiting of the domain name resolution process can be avoided, and the domain name resolution efficiency is improved.
