1 is a hardware frame diagram of a preferred embodiment of the web page conversion system of the present invention. The web page conversion system 10 runs in the application server 1. The application server 1 is configured to convert the local address input by the user into a valid address, access the webpage of the effective address in the target website server 4 through the Internet 3, and obtain a byte stream of the content of the webpage, The obtained byte stream is correspondingly processed, and a webpage is generated according to the processed byte stream for the user to browse. The application server 1 can be a personal computer, a web server, or any other suitable computer.

The application server 1 is connected to at least one client computer 2, so that the user can input the local address requesting access to the webpage to the application server 1, and the like.

As shown in FIG. 2, it is a functional module diagram of the webpage conversion system of the present invention. The webpage conversion system 10 includes a setup module 100, a replacement module 102, an access module 104, an acquisition module 106, a processing module 108, and a conversion module 110.

The setting module 100 is configured to set a location address corresponding to a valid address of a webpage, and save the set data to the application server 1. For example, the effective address of the webpage is http://xxx.sina.com, and the setting module 100 sets the local address of the webpage to http://localhost/hrs/sample.

The replacement module 102 is configured to replace the local address with a corresponding valid address when the user inputs the local address to request access to the webpage corresponding to the valid address. The current address refers to a virtual address in the local application server 1 of the webpage corresponding to the valid address, and the effective address refers to the actual address of the webpage corresponding to the valid address in the target website server 4. For example, if the user inputs the local address of the requesting webpage to be http://localhost/hrs/sample, and the corresponding effective address of the local address in the application server 1 is http://xxx.sina.com, The replacement module 102 replaces the home address with the valid address http://xxx.sina.com.

The access module 104 is configured to access the webpage corresponding to the valid address in the target website server 4 through the Internet 3.

The obtaining module 106 is configured to obtain a byte stream of the accessed webpage content. The byte stream of the webpage content refers to a data flow processed by the content of the webpage according to the byte group, that is, a binary data stream. The byte stream of the webpage content includes a picture byte stream and a string byte stream, the picture byte stream is used to display a picture in a webpage, and the string byte stream is used to display a webpage Text.

The processing module 108 is configured to convert a picture byte stream in the byte stream into a picture, and the string byte stream is converted into a string.

The processing module 108 is further configured to convert the link address in the string to a local absolute address. The link address in the string includes an absolute address and a relative address. The absolute address refers to the address with the full path (for example: http://xxx.sina.com/mil?id=123456), the relative address is only the server directory level and the file name (for example: /mil? Id=123456), and the browser only recognizes the absolute address, so the information of the relative address must be complemented, and the relative address can be converted into an absolute address to display normally. If the link address in the string is a relative address, the processing module 108 replaces the relative address with an absolute address, and then replaces the absolute address with a local absolute address by using a regular expression; The link address in the address is an absolute address, and the absolute address is directly replaced with a local absolute address by using a regular expression. For example, if the local address of the requested webpage is http://localhost/hrs/sample and the valid address is http://xxx.sina.com, the string of bytes obtained from the webpage has a relative position. Address /mil? Id=123456, the processing module 108 replaces the relative address with the absolute address http://xxx.sina.com/mil? Id=123456, then use the regular expression Will this absolute address be replaced with the local absolute address http://localhost/hrs/sample? q=http://xxx.sina.com/mil? Id=123456.

The conversion module 110 is configured to convert the picture and a string including a local absolute address into a webpage.

3 is a flow chart of a preferred embodiment of a web page conversion method according to the present invention. First, in step S10, the setting module 100 sets a location address corresponding to a valid address of a webpage, and saves the set data to the application server 1. For example, the effective address of the webpage is http://xxx.sina.com, and the setting module 100 sets the local address of the webpage to http://localhost/hrs/sample.

In step S12, when the user inputs the local address to request access to the webpage corresponding to the valid address, the replacement module 102 replaces the local address with the corresponding valid address. For example, if the user inputs the local address of the requesting webpage to be http://localhost/hrs/sample, and the corresponding effective address of the local address in the application server 1 is http://xxx.sina.com, The replacement module 102 replaces the home address with the valid address http://xxx.sina.com.

In step S14, the access module 104 accesses the webpage corresponding to the valid address in the target website server 4 through the Internet 3.

In step S16, the obtaining module 106 acquires a byte stream of the accessed webpage content. The byte stream of the webpage content refers to a data flow processed by the content of the webpage according to the byte group, that is, a binary data stream. The byte stream of the webpage content includes a picture byte stream and a string byte stream, the picture byte stream is used to display a picture in a webpage, and the string byte stream is used to display a webpage Text.

In step S18, the processing module 108 converts the picture byte stream in the byte stream into a picture, and the string byte stream is converted into a string.

In step S20, the processing module 108 converts the link address in the string into a local absolute address. The link address in the string includes an absolute address and a relative address. If the link address in the string is a relative address, the processing module 108 replaces the relative address with an absolute address, and then replaces the absolute address with a local absolute address by using a regular expression; The link address in the address is an absolute address, and the absolute address is directly replaced with a local absolute address by using a regular expression. For example, if the local address of the requested webpage is http://localhost/hrs/sample and the valid address is http://xxx.sina.com, the string of bytes obtained from the webpage has a relative position. Address /mil? Id=123456, the processing module 108 replaces the relative address with the absolute address http://xxx.sina.com/mil? Id=123456, and then use the regular expression to replace the absolute address with the local absolute address http://localhost/hrs/sample? q=http://xxx.sina.com/mil? Id=123456.

In step S22, the conversion module 110 converts the picture and the string including the local absolute address into a web page.
