Fig. 1 is a schematic diagram of an application environment according to an embodiment of the present invention. Referring to fig. 1, the computer device 1 provides a display interface, and the display interface includes a Chrome browser display page. After receiving a resource request input by a user through Chrome, the first URL in the resource request can be obtained, interception skipping is carried out according to an interception rule, a second URL is obtained, and a corresponding resource is obtained and displayed on a browser page. In the embodiment, the computer device 1 may be used as a terminal device such as a mobile terminal, e.g., a mobile phone, a tablet, a portable device, or a PC.
Example one
FIG. 2 is a flowchart illustrating an embodiment of a Chrome-based URL interception method according to the present invention. It is to be understood that the flow charts in the embodiments of the present method are not intended to limit the order in which the steps are performed. The following description is made by way of example with the computer apparatus 1 as the execution subject.
As shown in fig. 2, the Chrome-based URL intercepting method may include steps S200 to S204, where:
step S200, receiving a resource request input by a user, and acquiring a first URL in the resource request.
As shown in fig. 3, in an exemplary embodiment, the step S200 of obtaining the first URL in the resource request includes steps S300 to S302.
Step S300, registering the monitoring event in the Chrome extension program.
Step S302, when the resource request input by the user is received, the request object in the resource request is obtained through the monitoring event, and the first URL is extracted.
Specifically, the user inputs a resource request through the Chrome browser page of the computer device 1, and then the computer device 1 can receive the resource request input by the user and then obtain the first URL therein. In this embodiment, first, a monitoring event is registered in an extension program in the Chrome, and after a user inputs a resource request through the Chrome, the computer device 1 may obtain a request object in the resource request through the monitoring event, and then extract the first URL. In this embodiment, Chrome provides a function of registering an event in an extended program, for example, an onBeforeRequest event is registered in the extended program of Chrome, the onBeforeRequest event can record a resource request event occurring in Chrome, and then the computer device 1 may output the resource request event occurring in Chrome through an event callback function, so that the resource request may be acquired. When the resource request input to the Chrome by the user is obtained, the request object corresponding to the resource request can be further obtained, and then the first URL is extracted. In this embodiment, the computer device 1 registers a monitoring event through an extension program of the Chrome itself, monitors and acquires a resource request input by a user, and then obtains a corresponding first URL without depending on a third party service or an external additional function, so that the execution process is time-consuming and efficient.
Step S202, an interception rule is called from the Chrome extension program, and interception skip is carried out on the first URL according to the interception rule to obtain a corresponding second URL.
Specifically, the interception rule is an extension program written in the Chrome in advance and stored in a local storage unit corresponding to the Chrome, and after the first URL is obtained, the computer device 1 calls the interception rule to perform interception skip on the first URL. In this embodiment, the interception rule includes: when the first URL is judged to be the same as a second URL in a preset URL set, jumping to a resource page of the second URL; or when the first URL is judged to contain the target character string in the second URL, jumping to the resource page of the second RUL; or when judging that a first character string exists in the first URL and a second character string in a preset character string set are the same, replacing the first character string with the second character string to obtain a second URL, and jumping to a resource page of the second RUL; or when the first URL is judged to accord with a preset regular expression, replacing the first URL with the second URL, and jumping to the resource page of the second RUL.
The regular expression is also called a regular expression. (English: Regular Expression, often abbreviated in code as regex, regexp or RE), a concept of computer science. Regular expression (regular expression) describes a pattern of string matching, which can be used to check whether a string contains a certain substring, and replace the matched substring or extract a substring meeting a certain condition from a certain string, and the like. The components of the regular expression may be individual characters, a collection of characters, a range of characters, a selection between characters, or any combination of all of these components. Regular expressions are literal patterns composed of common characters (e.g., characters a through z) and special characters (called "meta characters"). The pattern describes one or more character strings to be matched when searching for text. The regular expression is used as a template to match a certain character pattern with the searched character string.
That is, the computer device 1 may implement omnibearing checking of the first URL and matching with the interception rule according to the interception rule; and after the first URL meets the matching condition of the interception rule, executing corresponding interception skip to obtain a second URL. In this embodiment, the second URL includes at least one of an empty resource, a local resource, an online resource, and a DataURI; and when the second URL is an empty resource, executing interception jumping is to block the resource request. The blocking request indicates that the request can be directly blocked by the browser and no response content is returned, so that abnormal fault tolerance processing needs to be carried out in the extension program, otherwise, the program can report an error. The local file representation may use a local file, such as C: \ tmp \ abc.txt or file:///C:/tmp/abc.txt or/usr/local/tmp/abc.txt as the request-response content.
Referring to fig. 4, in a specific embodiment, when the computer device 1 performs the interception skip according to the interception rule, since the interception rule includes a plurality of rules, the computer device 1 sequentially reads the rules one by one, and then matches the first URL with the rule; and when the first URL is matched with the rule, executing corresponding interception jump, then returning a result and ending. When the first URL is not matched with the rule, judging whether all the rules in the interception rule are read completely; when the reading is not finished, the next rule is continuously read; and returning a result after the reading is finished and ending.
And step S204, acquiring the resource corresponding to the second URL, and displaying the resource to a browser page.
As shown in FIG. 5, in an exemplary embodiment, the method further includes steps S400-S402.
And step S400, monitoring whether a new interception rule is written in the process of carrying out interception skip on the first URL according to the interception rule.
And step S402, when monitoring that a new interception rule is written, carrying out interception skip on the first URL according to the new interception rule.
Specifically, the computer device 1 monitors whether a new interception rule is written in real time, and when the new interception rule is written in, the interception skip can be executed according to the new interception rule, thereby implementing a dynamic interception function.
Additionally, in an exemplary embodiment, the method further comprises: and counting the first URL intercepted and jumped, and displaying the first URL to the Chrome page. By the method, the actual resource address in the resource access process can be counted, so that reference materials for setting the interception rule can be provided for the user, and the interception accuracy is further improved.
In summary, the Chrome-based URL intercepting method provided in this embodiment can obtain the first URL in the resource request after receiving the resource request input by the user; then calling an interception rule from the Chrome extension program, and carrying out interception skip on the first URL according to the interception rule to obtain a corresponding second URL; and finally, acquiring the resource corresponding to the second URL and displaying the resource to a browser page. The first URL address input by the user is judged and intercepted on the user side terminal equipment in a mode of writing the interception rule into the Chrome extension program. Therefore, the speed of accessing the target server by the user is effectively improved, the interception link of the intermediate equipment is reduced, and the data security is improved.
