Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 2. FIG. 2 is a flowchart of an implementation of a method for page jumping provided by an embodiment of the present application. The method includes:

Step S201, judging whether the user's click operation on the page number is received, if so, go to step S202;

In order to realize the page jump, the currently displayed page has the page number to be jumped to. As shown in FIG. 1 , the page number includes 1, 2, 3, 4 and so on.

Since the a tag is used to represent the page number in the prior art, and the a tag has the href attribute, the a tag automatically uses the GET method to transmit data when transmitting data. In this scheme, in order not to use the GET method to transmit data, the first tag is used to represent Page number, the first tag is a div tag or a tag with the href attribute removed.

When the user needs to browse the content on the page to be jumped, the user clicks the page number corresponding to the page to be jumped, and the click operation is used to trigger the first tag to start the data transmission function.

Step S202, calling the first function associated with the first label in response to the click operation;

The first function is used to obtain the page number and the identifier of the search tag.

In this embodiment, the first tag is associated with the first function, so that the transmission mode used when transmitting the data is selected by the first function.

Since the background server provides each page to the user, it needs to be retrieved from the database according to the key terms originally input by the user. Therefore, when the user clicks the page number on the page, in addition to transmitting the page number clicked by the user to the background server, it is also necessary to Get key terms that include keywords or keywords. Taking Figure 1 as an example, when the user enters the keyword "patent" on the first page of Baidu, page numbers 1, 2, 3, 4, etc. will appear on the jumped out page. In addition to the parameter of page number 3 transmitted from the server to the background server, the keyword "patent" also needs to be transmitted to the background server.

Since the key terms entered by the user are all input from the search tags on the page, before obtaining the key terms, the search tags for inputting the key terms must be obtained first, and the search tags can be form tags.

Step S203, obtaining key terms in the search tag through the identification;

The key term is the term entered by the user when searching the page;

Step S204: Add the key term and the page number to the HTTP packet body, and send it to the server.

In this embodiment, the first function associated with the first tag uses the POST method to transmit data. The so-called POST method refers to adding the transmission data to the HTTP packet body corresponding to the URL of the webpage where the page number is located, and sending the added data to the background server. The following HTTP body.

Http (ie web page) defines different methods for interacting with the server (background). There are four most basic methods, namely GET, POST, PUT, and DELETE. The full name of the URL is the resource descriptor, which is used to describe the resources on the network, and the four methods of GET, POST, PUT, and DELETE in HTTP correspond to the four operations of querying, modifying, adding, and deleting this resource. GET is generally used to obtain/query resource information, while POST is generally used to update resource information.

There are two main differences between sending data using GET and POST methods on web pages:

One is capacity:

The data submitted by the GET method can only be up to 1024 bytes. In theory, there is no limit to POST, and a large amount of data can be transmitted. The maximum size is 80KB in IIS4 and 100KB in IIS5. Although the description is not accurate, but the actual situation is roughly the same.

The second is security:

The data of the GET request will be appended to the URL (that is, the data will be placed in the HTTP protocol header), with ? Split the URL and transfer data, and connect the parameters with &, such as: login.action? name=hyddd&password=idontknow&verify=%E4%BD%A0%E5%A5%BD. If the data is English letters/numbers, send it as it is, if it is a space, convert it to +, if it is Chinese/other characters, directly encrypt the string with BASE64, and get such as: %E4%BD%A0%E5%A5% BD, where XX in %XX is the ASCII hex representation of the symbol.

POST places the submitted data in the body of the HTTP packet.

It can be seen from the above that the security of POST is higher than that of GET. For example, if you submit data via GET, the username and password will appear on the URL in plain text, because (1) the login page may be cached by the browser, and (2) others can view the browser's history, so others can get your account. In addition, using GET to submit data may also cause a Cross-site request forgery attack. Therefore, in this embodiment, the POST method is used to transmit data with higher security.

In the technical solution provided by this embodiment, the page number in the page is represented by a first label, the first label is associated with a first function, and the first function is used to obtain the page number and key terms clicked by the user, and use the page number and key terms. The term is added to the HTTP body and sent to the server. It can be seen from the above that the solution of the present application adopts the POST method to transmit data, and adds the data to the HTTP packet body for transmission, which is more secure than transmitting data through the HTTP protocol.

Please refer to FIG. 3. FIG. 3 is an implementation flowchart of a method for page jumping provided by an embodiment of the present application. The method includes:

Step S301, judging whether a user's click operation on the page number is received, if yes, perform step S302;

In order to realize the page jump, the currently displayed page has the page number to be jumped to. As shown in FIG. 1 , the page number includes 1, 2, 3, 4 and so on.

The page number on the page is represented by a div tag or a tag with the href attribute removed.

Since the a tag is used to represent the page number in the prior art, and the a tag has the href attribute, the a tag automatically uses the GET method to transmit data when transmitting data. In this scheme, in order not to use the GET method to transmit data, the div tag or remove The a tag of the href attribute represents the page number.

When the user needs to browse the content on the page to be jumped, click the page number corresponding to the page to be jumped, and the click operation is used to trigger the div tag or remove the a tag of the href attribute to start the data transmission function.

Step S302, in response to the click operation, call the function CiPageChange(url, id, pa) associated with the div tag or the a tag with the href attribute removed, and the function is used to obtain the page number and the first form tag. identification;

The url is the address of the page, the id is the identifier of the search tag, and the pa is the page number.

In this embodiment, the div tag or the a tag with the href attribute removed is associated with the function CiPageChange(url, id, pa), so that the transmission mode used for data transmission is selected through the function CiPageChange(url, id, pa).

Since the background server provides each page to the user, it needs to be retrieved from the database according to the key terms originally input by the user. Therefore, when the user clicks the page number on the page, in addition to transmitting the page number clicked by the user to the background server, it is also necessary to Get key terms that include keywords or keywords. Taking Figure 1 as an example, when the user enters the keyword "patent" on the first page of Baidu, page numbers 1, 2, 3, 4, etc. will appear on the jumped out page. In addition to the parameter of page number 3 transmitted from the server to the background server, the keyword "patent" also needs to be transmitted to the background server.

Since the key terms entered by the user are input from the form tag in the page, before obtaining the key terms, the form tag for inputting the key terms must be obtained first.

Step S303, obtaining key terms in the first form tag through the identification, where the key terms are terms input by the user when searching the page;

Step S304, adding the key term and the page number to the HTTP package body;

Step S305 , generating a second form tag, where the second form tag is used to trigger the HTTP packet body to the server.
