Description

Method and device for calling file

The present invention relates to the field of information technology, and in particular, to a method and device for calling a file.

In today's information society, the Internet has become an integral part of people's lives and work. When people browse a webpage, they usually establish a communication connection with the server through a browser (or an application with a browser kernel), so that the browser can send a request to the server to obtain a webpage page and obtain the server. After the browser returns the web page, the web page is displayed.

Because the webpage is composed of a set of codes (for example, composed of html5 code), and the code of the webpage points to various resource files (for example, JavaScript program source files, webpage style files, etc.) are also composed of respective codes , But the code is written manually, so as long as the code may have defects or flaws. Therefore, before the server provides a web page to the network (that is, before a web page goes online), generally, each code in the web page is tested in an offline environment, that is, an offline test is performed.

However, during offline testing, the server can only test the webpage using simulated online data, which makes the results of offline testing not necessarily accurate. Problems may also occur. At this time, the worker needs to debug the code of the resource file in question on the server side, but since the server is generally busy, the business that performs the debugging operation in the server may need to wait in line until an idle thread comes This debugging operation is performed, so that it takes a long time to debug each time the code of the problematic resource file. In addition, because it is difficult to solve the problems in the code of the resource file by only one debugging under normal circumstances, multiple debugging is required, which further increases the time required for debugging and solving the problem (especially when it is stored on other servers). When debugging the resource files in the system, a lot of transmission time is also wasted). Based on the above reasons, it is difficult for the staff to quickly and conveniently debug the resource files that have problems in the web page.

Therefore, in the prior art, for resource files that need to be debugged on a webpage, the http proxy method is used to map the resource files that need to be debugged to the terminal locally, so that the resource files can be debugged later using real online data, where The http proxy method is shown in Figure 1.

FIG. 1 is a prior art method of http proxy, which specifically includes: S101: Determine a resource file to be debugged in a webpage, and download the resource file as a resource file to be debugged.

Because the http proxy method hopes that the staff can complete the debugging of the resource file locally on the terminal, first the terminal needs to determine the resource file that needs to be debugged in the web page, and then download the file to the terminal locally for Is the resource file to be debugged so that the resource file to be debugged can be debugged later.

S102: Establish a virtual server, and determine an access path for the resource file to be debugged.

The resource file to be debugged needs to be obtained through a local browser. Specifically, the browser first obtains the access path of the resource file to be debugged (that is, the domain name of the resource file to be debugged) by running the code in the webpage, and then provides the resource to be debugged according to the access path. The server of the file initiates a request to call the resource file, and finally obtains the resource file to be debugged returned by the server.

However, because the staff wants to modify the resource file to be debugged directly locally, at this time, the terminal also needs to disguise itself as a server to deceive the browser and let the browser obtain the local content by running the same web page code. The downloaded resource file to be debugged. In order to achieve the purpose of locally debugging the resource file to be debugged on the terminal.

Specifically, the terminal needs to establish a local virtual server and determine an access path (ie, a virtual domain name of the resource file to be debugged) stored locally on the resource file to be debugged.

S103: Replace the access path for accessing the original resource file with the access path for accessing the local resource file to be debugged through the virtual server.

In order that when the browser in the terminal accesses the resource file through the webpage code, it no longer accesses the server of the resource file, but accesses the local virtual server. At this time, it is also necessary to modify the network configuration of the terminal so that the terminal receives the call to the resource file initiated by the browser. When a file is requested, the access path for accessing the resource file is replaced with the access path for accessing the local resource file to be debugged.

When the browser sends a request for calling the resource file to a server on the network, the virtual server receives the call request instead of the server on the network, and returns the resource file to be debugged to the server, and Make the browser determine that it received the resource file returned by the corresponding server on the network.

After downloading the resource file to be debugged locally by using the method described in FIG. 1 as the resource file to be debugged, the terminal debugs the resource file to be debugged locally, and the code in the webpage has not been changed. , So you can make full use of the real data online for debugging. Further, since the terminal can only be used for debugging the resource file to be debugged, each debugging process can be executed immediately without waiting, thereby improving debugging efficiency.

However, the process shown in FIG. 1 can only be implemented for a web page whose web page is a Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, http). For web pages that are Hyper Text Transfer Protocol over Secure Socket Layer (https), the communication between the browser and the server at this time needs to be encrypted for communication, that is, the browser needs The security certificate generated by the Secure Socket Layer (SSL) protocol is used to verify the identity of the server, and when receiving the resource file returned by the server, it is necessary to verify whether the resource file carries the corresponding security certificate.

However, since the virtual server does not have If the security certificate cannot provide a security certificate, the browser can neither verify the identity of the virtual server nor determine the security of the resource file to be debugged received by the virtual server. For the https page, The browser cannot even call the resource file to be debugged, which makes the staff unable to perform subsequent debugging work.

It can be seen that in the prior art, because there is no security certificate, it is difficult to proxy the https webpage, and the problem that the resource file to be debugged cannot be called.

Embodiments of the present invention provide a method and a device for invoking a file, which are used to solve an existing method for invoking a file. The http proxy method adopted in the method fails to provide a security certificate, which causes the browser to fail to call a resource file to be debugged.

A method for invoking a file provided by an embodiment of the present invention includes: receiving a replacement instruction for a network resource file in an https webpage; establishing a virtual server locally according to the replacement instruction; The access path of the network resource file is replaced with the access path of the local resource file to be debugged; a root certificate is generated for the virtual server; a sub-certificate is generated according to the root certificate, so that when the local browser When the https webpage initiates a call request for the network resource file, the virtual server receives the call request and sends the call request to the browser according to an access path replaced by a local resource file to be debugged. Return the resource file to be debugged and the sub-certificate, so that the browser root Obtaining and executing the resource file to be debugged according to the sub-certificate.

An embodiment of the present invention provides a file calling device, including: a receiving module for receiving a replacement instruction of a network resource file in an https webpage; an execution module for establishing a virtual server locally according to the replacement instruction; A replacement module for replacing an access path for accessing the network resource file with an access path for accessing a resource file to be debugged locally through the virtual server; a root certificate module for the The virtual server generates a root certificate; a sub-certificate module is configured to generate a sub-certificate according to the root certificate, so that when a local browser initiates a call request for the network resource file according to the https webpage, the The virtual server receives the invocation request, and returns the resource file to be debugged and the sub-certificate to the browser according to the access path replaced by accessing the local resource file to be debugged, so that the browser The sub-certificate obtains and executes the resource file to be debugged.

Embodiments of the present invention provide a method and a device for invoking a file. When a replacement instruction for a network resource file in an https webpage is received, a virtual server is locally established according to the replacement instruction, and the virtual server is used to pass the virtual server. The access path for accessing the network resource file is replaced with the access path for accessing the local resource file to be debugged, and then a root certificate and a sub-certificate are generated for the virtual server, so that when the local browser initiates the When a network resource file is called, it is received by the virtual server The calling request returns the resource file to be debugged and the sub-certificate to the browser, so that the browser can call and execute the resource file to be debugged according to the sub-certificate. Through the above method, since a root certificate and a corresponding sub-certificate are generated for the virtual server, the virtual server can provide a security certificate to the browser, so that the browser can normally call the resource file to be debugged.

The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present invention. The schematic embodiments of the present invention and the descriptions thereof are used to explain the present invention, and do not constitute an improper limitation on the present invention. In the drawings: FIG. 1 is a prior art http proxy process; FIG. 2 is a file calling process provided by an embodiment of the present invention; and FIG. 3 is a schematic structural diagram of a file calling device provided by an embodiment of the present invention.

In the embodiment of the present invention, when receiving a replacement instruction for a network resource in an https webpage, the terminal firstly establishes a virtual server locally on the terminal according to the instruction, and then passes the virtual server to the terminal. The access path for accessing the network resource file is replaced with the access path for accessing the local resource file to be debugged, and finally a root certificate and a corresponding sub-certificate are generated for the virtual server. It can be seen that the method according to the present invention A method for the server to generate a root certificate (that is, a self-signed certificate issued by the virtual server), so that the virtual server can deceive the browser, and make the browser determine that the virtual server is providing the web resource file in the https web page And when the local resource file to be debugged is returned to the browser, the sub-certificate generated by the root certificate may be returned together, so that the browser determines that the resource file to be debugged is a secure file, and finally makes The browser can call and execute the resource file to be debugged, which solves the problem that because the virtual server cannot provide a security certificate, it is difficult to proxy the https web page, and the resource file to be debugged cannot be called.

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described in combination with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art before making progressive creations fall within the protection scope of the present invention.

FIG. 2 is a file calling process provided by an embodiment of the present invention, which specifically includes the following steps: S201: Receive a replacement instruction for a network resource file in an https webpage.

Because the network resource file in the https webpage needs to be debugged locally on the terminal, before the debugging starts, the local resource file to be debugged needs to be replaced with the network resource file in the https webpage. However, since the debugging of the resource file to be debugged has not started at this time, The current resource file to be debugged may be any file, and may be a file that only has a file identifier and an address but has no corresponding content (that is, a blank file), which does not prevent the resource file to be debugged from being called subsequently.

Therefore, in the embodiment of the present invention, the terminal may receive a replacement instruction for the network resource file in the https webpage.

Specifically, the replacement instruction may be a command line for the terminal to determine a network resource file to be replaced and a resource file to be debugged that is stored locally in advance. The replacement instruction includes: the identification of the network resource file, the access path of the network resource file, the identification of the resource file to be debugged and the address of the resource file to be debugged.

It should be noted that the terminal may be a personal computer (PC), a mobile phone, a tablet computer, etc., and the network resource file may be a java script language (JavaScript, JS) program source file running on a browser, a cascade Files such as Cascading Style Sheets (css) files can be provided by the server through a Uniform Resource Locator (URL).

For example, if the music playback button in the https webpage A is clicked, the JS program source file (hereinafter, referred to as the audio JS file) used to call the local player application to play the audio file is returned to the browser, so that the https webpage A The specified audio file is played through the local player application, but after the staff member runs on the https page A and finds that the music playback button is clicked, the https page A does not play the audio file. Therefore, the staff member needs to PC on the https network The JS program source file where the problem occurred on page A.

It is further assumed that the PC receives a replacement instruction for the audio JS file (that is, a network resource file) in the https web page A, and the replacement instruction includes the identifier of the audio JS file: a.js, the audio JS File access path: https://www.XX.com/XX/a.js, the ID of the resource file to be debugged that is pre-saved locally on the PC: b.js, and the address of the resource file to be debugged: E: \ Debugging work \ file to be debugged \ b.js.

S202: Create a virtual server locally according to the replacement instruction.

In the embodiment of the present invention, the process of invoking the network resource file is as follows: The browser in the terminal determines the access path of the network resource file to be called by running the code of the https webpage, and then The server storing the web resource file initiates a request to call the web resource file (ie, initiates a call request according to the access path of the web resource file), and finally the browser receives the web resource returned by the server File and the sub-certificate provided by the server to complete the call to the network resource file.

However, in the present invention, since the browser needs to be able to call the local resource file to be debugged (so that the terminal can be debugged locally later), it is also necessary to provide the resource file to be debugged with a resource that the browser can access. Access path. Therefore, in the present invention, the terminal needs to be disguised as a virtual server storing the debugging resource file, and the domain name of the virtual server is determined, so that the browser can access the virtual server through the domain name of the virtual server. To generate an access path for the resource file to be debugged.

The specific process of establishing a virtual server locally on the terminal is consistent with the prior art. By establishing the virtual server and determining the domain name of the virtual server, the browser in the terminal can access the virtual server through the domain name of the virtual server to establish The local virtual server of the terminal establishes a basis for the browser to call the resource file to be debugged and saved locally.

Continuing the above example, it is assumed that after the PC receives the replacement instruction, a virtual server α is established on the PC, and its domain name is determined to be: https://www.YY.com.

S203: Replace the access path for accessing the network resource file with the access path for accessing the local resource file to be debugged through the virtual server.

In the embodiment of the present invention, after the virtual server is established, an access path can be generated for the resource file to be debugged, so that the browser can call the resource file to be debugged according to the access path of the resource file to be debugged. However, at this time, the browser accesses the path of the web resource file according to the web page code of the https web page, so the access path to access the web resource file needs to be replaced with the access to the resource file to be debugged. Access path.

Specifically, first, according to the domain name of the virtual server and the address of the file to be debugged, an access path of the file to be debugged (that is, the virtual domain name of the resource file to be debugged) is then considered as the resource to be debugged at this time. The file is a file stored in the virtual server.

Secondly, modify the network configuration of the terminal, and replace the access path for accessing the network resource file with the access path for accessing the resource file to be debugged. When the terminal receives an access, invocation, or query request based on the access path of the network resource file sent by the browser, the virtual server receives the access, Call, query request, and point the destination of the access, call, query request to the access path of the resource file to be debugged.

In addition, in order to run the https webpage with real online data to the greatest extent during subsequent debugging, and to ensure the reliability of the debugging results, in the present invention, only the access path for the network resource file can be modified to the resource to be debugged. File access path without changing the access path for other resource files issued by the browser, so that when the browser calls other resource files on the https page, the access path determined according to the https page is not Change, the browser finally calls other resource files on the network, and when the browser calls the network resource file, the access path determined by the browser is replaced with the resource file to be debugged pointing to the terminal locally. , The browser calls the resource file to be debugged, which is saved locally. Furthermore, in the subsequent debugging process, the browser can use the online real data to the greatest extent, so that the staff can only debug the debugging resource file.

It should be noted that the method for generating an access path for the resource to be debugged is the same as the prior art. An access path based on the virtual server domain name can be generated for the resource file to be debugged, and the access path and the The correspondence between the addresses of the resource files to be debugged enables the virtual server to determine the resource files to be debugged according to the access path.

Continue the above example, assuming that the PC passes the domain of the virtual server α Name https: //www.YY.com and the address E of the resource file b.js to be debugged: \ debugging work \ file to be debugged \ b.js to generate the access path of the resource file b.js to be debugged: https: //www.YY.com/b.js. In addition, the PC also replaced the access path https://www.XX.com/XX/a.js in the network configuration with https://www.YY.com/b.js. When the PC receives a call request for the audio JS file of the https web page A from the terminal browser B, the virtual server α receives the call request according to the access path modified in the network configuration, and Take the path https: //www.YY.com/b.js and call the resource file b.js to be debugged.

S204: Generate a root certificate for the virtual server.

In the embodiment of the present invention, it has been stated in step S101 that the present invention is based on an https webpage. For an https webpage, the transmission between the browser and the virtual server needs to be encrypted for communication. Therefore, in order to make the virtual The server can encrypt the communication with the browser, and also needs to generate a root certificate for the virtual server.

Specifically, since the root certificate is only used in the terminal as the security certificate of the virtual server, there is no need for an authoritative and high credibility security certificate (for example, a certificate authority, a CA issued by a Certificate Authority), and only It is necessary to be able to deceive the browser so that the browser can encrypt the communication with the transmission of the virtual servo device.

It should be noted that the root certificate is various types of security certificates, such as Domain Validation SSL (DVSSL) certificates, Organization Validation SSL (OVSSL) certificates, and Extended Validation SSL (EVSSL). ) The certificate and the wildcard SSL (Wildcard SSL) certificate are not specifically limited in the present invention.

Continuing the above example, suppose that a root certificate β is generated for the virtual server α.

S205: Generate a sub-certificate according to the root certificate.

In the embodiment of the present invention, after a root certificate is generated for the virtual server (that is, after a self-signed certificate is issued for the virtual server), in order to enable the browser to call the to-be-debugged file saved locally on the terminal. Resource file, the virtual server may also generate a sub-certificate for sending to the browser according to the root certificate, so that the browser may determine that the resource file to be debugged is safe according to the sub-certificate. After the root certificate and its sub-certificates are generated, the browser can communicate with the virtual server based on the https web page.

Specifically consistent with the prior art, the virtual server generates a sub-certificate for sending to the browser based on the root certificate, so that when the browser in the terminal initiates a call to the network resource file according to the https webpage When requested, the virtual server receives the invocation request, and returns the resource file to be debugged and the sub-certificate to the browser according to the access path replaced by access to the local resource file to be debugged, thereby enabling the browser According to the sub-certificate, it is determined that the resource file to be debugged is secure, and the resource file to be debugged is obtained and executed.

Continuing the above example, assuming that the virtual server generates a sub-certificate γ based on the root certificate β, when the browser B initiates to https://www.XX.com/XX/a.js according to the https page A When the request is called, the virtual server Server α receives the call request to https://www.YY.com/b.js, then the virtual server α returns the resource file b.js to be debugged and the sub-certificate γ to the browser, so that After receiving the resource file b.js to be debugged and the sub-certificate γ, the browser B determines that the resource file b.js to be debugged is safe and available according to the sub-certificate γ, and obtains and executes the resource file b.js to be debugged. .

By calling the file method shown in FIG. 2, it can be seen that since the root certificate and the sub-certificate are generated for the virtual server, the virtual server also has an invocation request for a network resource file initiated by the browser according to the https webpage. The browser can be spoofed by the root certificate, so that the browser determines that the virtual server is a server that provides the network resource file in the https web page, and the virtual service returns the resource file to be debugged to the browser And the sub-certificate, so that the resource file to be debugged can trick the browser through the sub-certificate, and let the browser determine that the identity of the resource file to be debugged is secure. Thereby, the replacement of the network resource files in the https web page is realized, and the browser can obtain and execute the local resource files to be debugged. This enables the staff to debug the network resource files in the https webpage where the problem occurs in the terminal.

In addition, as described in step S201, the resource file to be debugged may be any file, so in order to debug the resource file to be debugged later, in the present invention, the network resource file may also be downloaded to the file to be debugged. The address of the debug resource file.

Specifically, the terminal may determine the access path of the network resource file according to the replacement instruction, and download the path according to the access path of the network resource file. The address of the network resource file to the resource file to be debugged. At this time, the resource file to be debugged is no longer an arbitrary file, but has been replaced with the downloaded network resource file, so subsequent staff can localize the file. The resource file to be debugged is debugged.

It should be noted that the downloading of the network resource file and the replacement of the resource file to be debugged can be performed in any step of the present invention. It only needs to ensure that the access path of the resource file to be debugged generated in step S203 is The access path of the resource file to be debugged has been replaced with the network resource file.
