Embodiments of the invention disclose a method and a device for identifying a web crawler. The method comprises: receiving an access request sent by an IP address, counting a website traffic corresponding to the IP address in real time according to the access request, and obtaining access frequency corresponding to the IP address according to the website traffic; and if the access frequency of the IP address is larger than a preset threshold, determining a user corresponding to the IP address as the web crawler. It can be seen from the above contents that, when the method is used for identifying the web crawler, a log of a website server does not need to be analyzed, while the website traffic of the IP address is counted in real time when receiving the access request sent by the IP address, so as to quickly obtain the access frequency of a certain IP address in real time. That is, the web crawler is quickly identified in a crawling process of the web crawler to improve the instantaneity of identifying the web crawler, so that vicious web crawlers can be shielded quickly.

The invention discloses version management and file pulling control methods for static files, version management and file pulling control devices, and a version control system. The version management method for the static files includes: a version number is marked at each static file in the at least one static file, the static files marked with the version numbers are regarded as to-be-released files; a version configuration file corresponding to at least one to-be-released file is generated; the version configuration file comprises a file name and the information of the version number of the at least one to-be-released file; and the at least one to-be-released file is released in a content distribution network server, and the version configuration file is released in an operation server in a gated launch manner. According to the technical scheme, clear management and control of static file versions can be realized, the chaos of the static file versions is avoided, and rollback, gated launch, and incremental release of the static files can be supported.

The invention provides a Web-based crawler identification algorithm. The algorithm comprises the steps of setting a trap and judging a crawler probability by analyzing a behavior characteristic of user access online; for a visitor with high crawler probability, requiring verification by a verification code to reduce false judgment; analyzing data in a day offline and correctly identifying a crawler with good hiding performance through a large amount of data; and adding the identified crawler into a determined list library. According to the algorithm, online real-time identification and offline correct identification are combined; and while the real-time property of identification is ensured, the accuracy of identification is improved and the false judgment is reduced.

The invention discloses a method and apparatus for obtaining active user data of target product. The method comprises: obtaining the search data in a plurality of periods of a target product in a third-party data platform; determining the correlation between the search data and the newly increased user number in the same period of a basic product so as to determine the predicted newly increased user number in the same period of the target product; according to the user remaining rate of the basic product in previous periods, fitting a remaining curve; based on the remaining curve and the newly increased user number in the observation period, obtaining the predicted active user number of the target product in the observation period; combining a preset algorithm, obtaining the active user number of the target product in the observation period; based on the correlation among the remaining user number, the newly increased user number, the active user number and the daily active user number, creating a daily active user number prediction model; and combining the already known corresponding data of the target product to output the daily active user number of the target product so as to realize the quantified monitoring on the daily active user number. With the method proposed by the invention, it is possible to realize the quantified monitoring on the daily active user number.

The invention relates to a resource allocation method and a resource allocation device. The resource allocation method comprises the following steps: receiving a resource acquisition request sent by a client side, and inquiring whether a user on the client side is a user who has acquired resources to be allocated according to the resource acquisition request, wherein the resource acquisition request carries user identifiers; if the user on the client side is a user who has not acquired the resources to be allocated, reading the resources to be allocated from a distributed cache buffer, and returning the resources to be allocated to the client side, wherein the distributed cache server comprises a first queue which is used for storing identifiers of the resources to be distributed. The embodiments of the resource allocation method and the resource allocation device are capable of meeting the demands of synchronous access by massive users and thus are capable of ensuring normal operation of a website or APP (Application).

The invention relates to a web crawler detecting method and device and aims to save operating and maintenance cost of a server. The method includes: on receiving an access request from a client, determining whether or not a request requiring execution of a preset identification file is received; if not, returning a verification page to the client; if the client fails to pass verification on the verification page, determining a crawler request, under monitoring, of the access request, adding an IP (internet protocol) address of the client to a first black list. The web crawler detecting method and device according to the technical scheme has the advantages that crawler behaviors can be discovered in quasi-real time through the crawler request under monitoring, the manual way of adding the network crawler under monitoring to the first black list is avoided, operating and maintenance cost of the server is decreased, fewer server resources are used by malicious accesses, and better services are provided for users.
