Description

Method and device for calling a file

The present invention relates to the field of information technology, and more particularly to a method and apparatus for calling a file.

In today's information society, the Internet has become an indispensable part of people's lives and work. When browsing a webpage, a person generally establishes a communication connection with a server through a browser (or an application having a browser kernel), so that the browser can send a request for obtaining a webpage page to the server, and obtain the servo. After the page page returned by the device, the page page is displayed.

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

However, in the offline test, the server can only use the simulated online data to test the webpage, which makes the offline test result not necessarily accurate, that is, the offline test determines the webpage without problems, after going online There may also be problems. At this time, the staff needs to debug the code of the resource file in question on the server side, but since the server is generally busy, the service performing the debugging operation in the server may need to wait in line until there is an idle thread. The debug operation is performed, so it takes a long time to debug the code of the resource file that has the problem each time. Moreover, since it is difficult to solve the problem in the code of the resource file by one debugging in a normal situation, it is necessary to perform multiple debugging, so the time required for debugging to solve the problem is further increased (especially when the pair is stored in other servers). When debugging resource files in the middle, it also needs to waste a lot of transfer time). For the above reasons, it is difficult for the staff to quickly and conveniently debug the resource files that have problems in the webpage.

Therefore, in the prior art, the resource file that needs to be debugged in the webpage is mapped to the terminal by using the http proxy method, so that the resource file can be debugged by using the real online data. The http proxy method is shown in Figure 1.

FIG. 1 is a method of a prior art http proxy, specifically including: S101: determining a resource file that needs to be debugged in a webpage, and downloading the resource file as a resource file to be debugged.

Because of the http proxy method, it is hoped that the staff can complete the debugging of the resource file locally in the terminal, so firstly, the end needs to determine the resource file that needs to be debugged in the webpage, and then download the file to the terminal locally. 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 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 invoke the resource file, and finally obtains the resource file to be debugged returned by the server.

However, since the staff wants to directly modify the resource file to be debugged locally, at this time, the terminal also needs to be disguised as a server to deceive the browser, so that the browser obtains the local by running the same webpage code. The resource file to be debugged that has been downloaded. To achieve the purpose of debugging the resource file to be debugged locally on the terminal.

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

S103: Replace, by the virtual server, an access path for accessing the original resource file to an access path for accessing the local resource file to be debugged.

In order to enable the browser in the terminal to access the resource file through the webpage code, the server of the resource file is no longer accessed, but the local virtual server is accessed. At this time, the network configuration of the terminal needs to be modified, so that the terminal receives the resource message initiated by the browser. When the request is made, 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 to the server on the network to invoke the resource file, the virtual server replaces the server on the network to receive the call request, and returns the resource file to be debugged to the server, and Let the browser determine that the resource file returned by the corresponding server on the network is received.

After the resource file to be debugged is downloaded to the local device as the resource file to be debugged, the resource file to be debugged is debugged locally on the terminal, and the code in the webpage is not changed. So you can make full use of the real data on the line for debugging. Further, since the terminal can be used only for debugging the resource file to be debugged, each debugging process can be executed immediately without waiting, which improves 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 (http). For a webpage whose webpage is a Hyper Text Transfer Protocol over Secure Socket Layer (https), the transmission between the browser and the server needs to be encrypted by 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, due to the process shown in Figure 1, the virtual server does not have If the security certificate cannot provide a security certificate, the browser cannot verify the identity of the virtual server, nor can it determine the security of the resource file to be debugged returned by the virtual server. For the https webpage, 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, since there is no security certificate, it is difficult to perform proxying of the https webpage, and the problem of the resource file to be debugged cannot be called.

The embodiment of the present invention provides a method and a device for calling a file, which are used to solve the problem that the existing proxy file method and the http proxy method are used, and the browser cannot be used to debug the resource file to be debugged because the security certificate cannot be provided.

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

The embodiment of the present invention provides a call file device, comprising: a receiving module, configured to receive a replacement instruction of a network resource file in a https webpage; and an execution module, configured to establish a virtual server locally according to the replacement instruction; a replacement module, configured to replace, by the virtual server, an access path for accessing the network resource file with an access path for accessing a local resource file to be debugged; a root certificate module, configured to The virtual server generates a root certificate, and the sub-certificate module is configured to generate a sub-certificate according to the root certificate, so that when the local browser initiates a call request for the network resource file according to the https webpage, Receiving, by the virtual server, the call request, and returning the to-be-debuved resource file and the sub-certificate to the browser according to an access path replaced with accessing the local to-be-debug resource file, so that the browser is configured according to the browser The sub-certificate acquires and executes the resource file to be debugged.

An embodiment of the present invention provides a method and an apparatus for calling a file. When receiving a replacement instruction for a network resource file in a https webpage, the method establishes a virtual server locally according to the replacement instruction, and uses the virtual server to Accessing the access path of the network resource file is replaced by accessing the access path of the local resource file to be debugged, and then generating a root certificate and a sub-certificate for the virtual server, so that the local browser initiates the Received by the virtual server when a request for a network resource file is invoked The calling request returns the resource file to be debugged and the sub-certificate to the browser, and finally enables the browser to call and execute the resource file to be debugged according to the sub-certificate. Through the above method, since the root certificate and the corresponding sub-certificate are generated for the virtual server, the virtual server can provide the browser with a security certificate, so that the browser can call the resource file to be debugged normally.

In the drawings: FIG. 1 is a prior art http proxy process; FIG. 2 is a call file process according to an embodiment of the present invention; FIG. 3 is a schematic structural diagram of a call file device according to an embodiment of the present invention.

In the embodiment of the present invention, when receiving the replacement instruction for the network resource in the https webpage, the terminal first establishes a virtual server locally on the terminal according to the instruction, and then uses the virtual server to connect the terminal. The access path for accessing the network resource file is replaced with an access path for accessing the local resource file to be debugged, and finally the root certificate and the corresponding sub-certificate are generated for the virtual server. The method of the present invention can be seen by using the virtual servo The server generates a root certificate (ie, a self-signed certificate issued by the virtual server), so that the virtual server can spoof the browser, so that the browser determines that the virtual server is providing a network resource file in the https webpage. The server, and when returning the local resource file to be debugged 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 The browser can call and execute the resource file to be debugged, and solves the problem that the virtual server cannot provide the security certificate, which makes it difficult to perform the proxy of the https webpage and cannot call the resource file to be debugged.

The technical solutions of the present invention will be clearly and completely described in conjunction with the specific embodiments of the present invention and the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. Based on the embodiments of the present invention, it is within the scope of the present invention to provide all other embodiments obtained by those skilled in the art without making a progressive creation.

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

The network resource file in the https web page needs to be debugged locally. Therefore, before the debugging starts, the local resource file to be debugged needs to be replaced with the network resource file in the https web page. However, since the debugging of the resource file to be debugged has not started yet, The current resource file to be debugged may be any file, and may be a file that only has the file identifier and the address but has no corresponding content (ie, is a blank file), and does not prevent the subsequent resource file to be debugged from being called.

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 line of command lines for the terminal to determine a network resource file that needs to be replaced and a resource file to be debugged that is saved in advance. The replacement instruction includes: an identifier of the network resource file, an access path of the network resource file, an identifier of the to-be-debug resource file saved in advance, and an 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 javascript language (JavaScript, JS) program source file running on a browser, and cascading. A Cascading Style Sheets (css) file or the like can be provided by a server through a Uniform Resource Locator (URL).

For example, suppose that the music play button in the https webpage A returns a JS program source file (hereinafter referred to as an audio JS file) for calling the local player application to play the audio file after being clicked, so that the https webpage A The specified audio file is played by the local player application, but after the staff runs online on the https webpage A, it is found that after the music play button is clicked, the https webpage A does not play the audio file, so the staff member needs to be in himself. PC on the https network The JS program source file that has a problem in page A.

Further suppose that the PC receives a replacement instruction for the audio JS file (ie, the network resource file) in the https webpage 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 locally saved by the PC: b.js and the address of the resource file to be debugged: E:\ Debug work\to be debugged file\b.js.

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

In the embodiment of the present invention, the calling process of the network resource file is normally: the browser in the terminal first 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 network resource file initiates a request to invoke the network resource file (ie, initiates a call request according to an access path of the network resource file), and finally the browser receives the network resource returned by the server. The file and the sub-certificate provided by the server complete the call to the network resource file.

However, in the present invention, since the browser needs to call the local resource file to be debugged (so that it can be debugged locally in the terminal), it is also necessary to provide the browser resource to be debugged with a browser accessible. Access path. Therefore, in the present invention, the terminal needs to be pretending to store the virtual server with the debug resource file, and the domain name of the virtual server is determined, so that the browser can access the virtual servo through the domain name of the virtual server. In order to subsequently generate an access path for the resource file to be debugged.

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

Continuing with the above example, it is assumed that the PC establishes the virtual server α on the PC after receiving the replacement instruction, and determines that the domain name is: https://www.YY.com.

S203: Replace, by the virtual server, an access path for accessing the network resource file to an access path for accessing a local resource file to be debugged.

In the embodiment of the present invention, after the virtual server is established, an access path may be generated for the resource file to be debugged, so that the browser can invoke 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 network resource file according to the webpage code of the https webpage, so it is also necessary to replace the access path of accessing the network resource file to access the resource file to be debugged. Access path.

Specifically, the accessing path of the file to be debugged (that is, the virtual domain name of the resource file to be debugged) is generated according to the domain name of the virtual server and the address of the file to be debugged. A file is a file stored in the virtual server.

Secondly, the network configuration of the terminal is modified, and the access path for accessing the network resource file is replaced with an access path for accessing the resource file to be debugged. When the terminal receives an access, call or query request based on the access path of the network resource file sent by the browser, the virtual server receives the access according to the replacement relationship of the access path. The request is invoked, the request is made, and the destination of the access, call, and query request is directed to the access path of the resource file to be debugged.

In addition, in the subsequent debugging process, the https webpage can be run to the greatest extent by using the real data on the line to ensure the reliability of the debugging result. In the present invention, only the access path for the network resource file can be modified as the resource to be debugged. The access path of the file without changing the access path of other resource files issued by the browser, so that when the browser is calling other resource files on the https webpage, the access path determined according to the https webpage is not Change, the browser finally calls other resource files on the network, and when the browser invokes the network resource file, the access path determined by the browser is replaced with the resource file to be debugged locally to the terminal. The browser calls the locally saved resource file to be debugged. In addition, in the subsequent debugging process, the browser can use the real data on the line to the maximum extent, so that the staff can debug only 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, and an access path based on the virtual server domain name may be generated for the resource file to be debugged, and the access path is recorded. Corresponding relationship of the address of the resource file to be debugged, so that the virtual server can determine the resource file to be debugged according to the access path.

Continue to use the above example, assuming that the PC passes the domain of the virtual server α Name https://www.YY.com and the address of the resource file b.js to be debugged E:\Debug work\to be debugged file\b.js, the access path of the resource file b.js to be debugged is generated: Https://www.YY.com/b.js. Also, the PC replaces 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 the call request from the terminal browser B for the audio JS file of the https webpage A, the virtual server a receives the call request according to the modified access path in the network configuration, and according to the save request Take the path https://www.YY.com/b.js to 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 a https webpage, and for the https webpage, the transmission between the browser and the virtual server needs to be encrypted by communication, so that in order to make the virtual The server can encrypt and encrypt the transmission with the browser, and also needs to generate a root certificate for the virtual server.

Specifically, since the root certificate is only used as the security certificate of the virtual server in the terminal, an authoritative and highly credible security certificate (for example, a certificate authority, a certificate issued by a certificate authority) is not required. The browser needs to be able to spoof the browser so that the browser can communicate 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) certificate, Enterprise SSL (Organization Validation SSL, OVSSL) certificate, and Extended SSL (Extended Validation SSL, EVSSL). ) The certificate and the wildcard SSL certificate are not specifically limited in the present invention.

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

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

In the embodiment of the present invention, after the root certificate is generated for the virtual server (that is, after the virtual server is issued the self-signed certificate), in order to enable the browser to call the to-be-debug stored locally in the terminal. The resource file, the virtual server may further generate a sub-certificate for sending to the browser according to the root certificate, so that the browser may determine, according to the sub-certificate, that the to-be-debug resource file is secure. After the root certificate and its sub-certificates are generated, the browser can perform a https-based web-based communication connection with the virtual server.

Specifically, in accordance with the prior art, the virtual server generates a sub-certificate for sending to the browser based on the root certificate, so that the browser in the terminal initiates a call to the network resource file according to the https webpage. At the request, the virtual server receives the call request, and returns the resource file to be debugged and the sub-certificate to the browser according to the access path that is replaced by accessing the local resource file to be debugged, thereby causing the browser to The resource file to be debugged is determined to be secure according to the sub-certificate, and the resource file to be debugged is obtained and executed.

Continuing with the above example, assume that the virtual server generates the sub-certificate γ according to the root certificate β, then when the browser B is launched according to the https page A to https://www.XX.com/XX/a.js The virtual servo when the request is called The server a receives the call request initiated to https://www.YY.com/b.js, and the virtual server α returns the resource file b.js to be debugged and the sub-certificate γ to the browser, so that the server 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 safely available according to the sub-certificate γ, and obtains and executes the resource file b.js to be debugged. .

Through the call 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, even if the browser requests the web resource file initiated by the browser according to the https webpage, the virtual server also The browser may be spoofed by the root certificate, so that the browser determines that the virtual server is a server that provides a network resource file in the https webpage, and the virtual service returns the resource file to be debugged by returning to the browser. And the sub-certificate, so that the to-be-debug resource file can spoof the browser by using the sub-certificate, so that the browser determines that the identity of the resource file to be debugged is secure. Thereby, the replacement of the network resource file in the https webpage is implemented, and the browser can acquire and execute the local resource file to be debugged. The staff can then debug the network resource files in the https webpage where the problem occurs locally.

In addition, as described in step S201, the resource file to be debugged may be an arbitrary file, so that the network resource file may be downloaded to the standby in the present invention. The address of the debug resource file.

Specifically, the terminal may determine an access path of the network resource file according to the replacement instruction, and download according to an access path of the network resource file. The network resource file is the address of 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 that the follow-up staff can locally 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 may be performed in any step of the present invention, and only the access path of the resource file to be debug generated in step S203 is required to be It can be replaced with the access path of the resource file to be debugged of the network resource file.
