Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram illustrating the main steps of a method for determining a root domain name of a website according to an embodiment of the present invention.
As shown in fig. 1, the method for determining a root domain name of a website according to the embodiment of the present invention may be specifically executed according to the following steps:
step S101: the domain name portion in the target URL is extracted.
In the embodiment of the present invention, the website root domain name refers to the root domain name of one site, which is different from the "root domain name" in "13 root domain name servers all over the world". For example, the domain name of a site search service is "www.test.com", the domain name of a translation service is "fanyi. It can be seen that for any website domain name, which is composed of multiple elements (typically, one element is a word), any two adjacent elements are separated by a separator ". times.. Generally, for any website domain name, the rightmost element of the website domain name may be referred to as a top-level domain name (also referred to as a first-level domain name), and a second-level domain name, a third-level domain name, a fourth-level domain name, and the like may be sequentially arranged from left to right. At present, three types of top-level domain names are shared in a domain name system on the internet, namely category top-level domain names (such as com, net, org, gov and the like), geographic top-level domain names (such as cn, uk and the like), and new top-level domain names (such as aero, biz, coop and the like).
In this step, the domain name portion in the target URL may be extracted first. It will be appreciated that the web page URL is generally comprised of a protocol section (e.g., http:), a domain name section, a port section (e.g., 8080), a virtual directory section (e.g.,/a/b), a parameter section, and the like. In some embodiments, the domain name portion may be extracted using a document domain name attribute (i.e., domain main) of a browser script (e.g., JavaScript), and for example, the domain name portion may be obtained by inputting JavaScript: alert in an address bar of a page corresponding to the target URL. In the area of front-end technology, alert is a method for displaying a specified message.
Step S102: and selecting two elements at the rightmost end of the domain name part to construct the current domain name.
After the domain name part of the target URL is obtained, the website root domain name can be obtained by utilizing the characteristic that the browser can only write cookies under a legal domain name. Because the website root domain name is necessarily composed of two or more than two elements at the right end of the domain name part, the two elements at the rightmost end of the domain name part are selected to construct the current domain name in the step. It will be appreciated that the current domain name needs to be constructed while maintaining the order of the elements in the domain name portion, and while retaining the delimiter. For example, if the domain name portion extracted from the target URL is "www.test.com.cn", the current domain name constructed in this step is "com.
Step S103: the operation of creating the cookie file is performed under the current domain name.
In the field of computer technology, a cookie refers to a text file stored in a user terminal and data therein, and a server can recognize a user state through cookie information carried when the user terminal sends a request. Preferably, in the embodiment of the present invention, a cookie-related attribute (i.e., document cookie) in JavaScript may be used to attempt to create and save a cookie file. Specifically, custom cookie file identification data (e.g., the name of the cookie file and the value of the cookie file) and the current domain name may be assigned to the document. For example, a code document, cookie _ test 1; cn performs the above assignment. It is to be understood that "_ cookie _ test" in the above code is the name of the cookie file to be created, "1" is the value of the cookie file to be created, "domain" is the domain name attribute of the cookie file, and "com.
Step S104: and after the operation is finished, judging whether the cookie file exists under the current domain name.
In this step, after the operation of creating the cookie file is completed, cookie file information under the current domain name may be read based on the document. If the cookie file identification data exists in the returned data, which indicates that the cookie file is successfully created and the corresponding current domain name is legal, the current domain name is determined as the website root domain name corresponding to the target URL (i.e., step S105). Generally, all cookie file information under the current domain name can be obtained by reading the document.
If the cookie file identification data does not exist in the returned data, indicating that the creation of the cookie file fails, at this time, the rightmost element that is not selected in the domain name part may be spliced to the current domain name to form a new current domain name, and the aforementioned steps of creating the cookie file and determining whether the creation of the cookie file is successful are performed again until the website root domain name is determined (i.e., step S106).
For example, under the current domain name "com.cn", document.cookie _ cookie _ test 1 is executed; cn to try to create a cookie file, the cookie may be read to obtain cookie file information under the current domain name "com. In practical application, it can be found that corresponding cookie file identification data "_ cookie _ test ═ 1" does not exist in the returned data, which indicates that creating a cookie file before the time is failed, at this time, the rightmost element "test" that is not selected in the domain name part "www.test.com.cn" may be spliced to the current domain name "com.cn" to form a new current domain name "test.com.cn", and the steps of creating a cookie file and determining whether the cookie file is successful or not are executed again under the new current domain name "test.com.cn", that is, the step of executing document. Com.cn to try to create a cookie file, and thereafter reads the cookie to acquire cookie file information under the current domain name "test. In practical application, it can be found that cookie file identification data "_ cookie _ test ═ 1" exists in the returned character string data, which indicates that the current domain name is legal, and the current domain name "test.
In specific application, if the current domain name is illegal, the cookie file cannot be successfully created under the current domain name, and no cookie file exists under the current domain name; creating a cookie file under the current domain name is generally successful if the current domain name is legitimate, and there may be other cookie files under the current domain name in addition to this cookie file created. Thus, in some embodiments, whether the cookie file was created successfully may be determined by: and if the returned data is null after the document cookie attribute is read, the creation is failed, and if the returned data is not null, the creation is successful.
Preferably, since the cookie file created in the above process has no typical role of the cookie file, the created cookie file may be deleted after determining the website root domain name corresponding to the target URL. Specifically, cookie file identification data used when creating a cookie file and expiration time data whose value is zero may be assigned to the document. And (5) deleting the created cookie file if maxAge is 0. It is understood that maxAge in the above instructions is the expiration time attribute of the cookie file.
Fig. 2 is a schematic diagram of a specific implementation of the method for determining a root domain name of a website in the embodiment of the present invention, and specifically executes the following steps: step S201: after the domain name part is extracted from the target URL, a preset regular expression is used for matching with the domain name part. In this step, a small number of regular expressions can be written based on the most common top-level domain names com, cn, com. Step S202: and judging whether the matching is successful, if so, obtaining the website root domain name (namely step S205), and ending the process. Step S203: and if the matching is judged to be failed, constructing the current domain name according to the method, and trying to create a cookie file under the current domain name. Step S204: whether creating the cookie file is successful is determined using the aforementioned method. Step S205: if the creation is successful, the website root domain name is obtained, and the process is ended. In step S206, if the creation fails, a new current domain name is constructed by using the aforementioned method, and step S203 and step S204 are executed again until the website root domain name is finally obtained.
According to the technical scheme of the embodiment of the invention, firstly, a domain name part in a target URL is extracted, then two elements at the rightmost end of the domain name part are selected to construct a current domain name, cookie creation is tried under the current domain name, and if the cookie creation is successful, the current domain name is indicated to be a website root domain name corresponding to the target URL; if the creation is failed, the current domain name is not legal, at this time, the right-most end elements which are not selected in the domain name part can be spliced with the current domain name to form a new current domain name, and the steps of creating the cookie file and judging whether the creation is successful or not are repeatedly executed until the corresponding website root domain name is obtained. The method obtains the website root domain name by utilizing the characteristic that the browser can only write the cookie under the legal domain name, and realizes accurate identification of the website root domain name on the premise of not influencing the loading performance of the website.
