Description

HTTP REDIRECT STATUS CODE CAPTURE METHOD AND APPARATUS, AND
COMPUTER DEVICE
BACKGROUND OF THE INVENTION
Technical Field [0001] The present application relates to the field of internet technology, and more particularly to a method and a device for capturing an Http redirecting status code, and corresponding computer equipment and storage medium.
Description of Related Art

[0002] With the development of the intemet technology, the applet technology has come into being. An applet is an application program carried in any other platform (such as the WeChat platform, Baidu platform or TouTiao platform) and ready for use in the platform without prior downloading and installation.

[0003] Out of considerations for security, it is required in the Web system by many requests that the user be in a login status (referred to as constrained resource). It is modus operandi while processing the constrained resource to jump perforce to the login page when it is determined that the user is not in the login status. However, since the underlying request of an applet is not like a browser request, the request of the applet does not support Http (Hypertext transfer protocol) redirecting status codes. The conventional solving scheme is to firstly invoke the interface of the server end to judge the login status of the user. With respect to the applet end, since all requests would be each added with another request to judge whether the user has logged in, such additional requests necessarily cause delay of the response.

Date Recue/Date Received 2022-03-04

[0055] The method of capturing an Http redirecting status code provided by the present application is applicable to the application environment as shown in Fig. 1-1.
The application environment includes terminal 102, network 104 and business system 106, wherein terminal 102 and business system 106 can be communicably connected via network 104. The network system consisting of terminal 102, network 104 and server 106 can be based either on the internet or on a local area network, and can be further based on a combined network based both on the internet and the local area network, to which no explanation is redundantly made in this context.

[0056] Terminal 102 can be, but is not limited to be, any of various personal computers, notebook computers, smart mobile phones, panel computers and portable wearable devices.
What is shown in Fig. 1-1 is the case in which terminal 102 includes two terminals, namely terminal 1022 and terminal 1024, but the present application makes no restriction to the number of terminal(s) 102, as more or less terminal(s) can as well be included. An applet application operative on terminal 102 is an application useable without prior downloading and installation, such as a WeChat applet operative under WeChat environment or a Baidu applet operative under Baidu environment.

[0057] Network 104 is used to realize network connection between terminal 102 and business system 106, and can include plural types of wired or wireless networks.
Terminal 104 can include the internet, a local area network ("LAN"), a wide area network ("WAN"), an intranet, a mobile telephone network, a virtual private network (VPN), a cellular or any other type of mobile communication network, the Bluetooth, NFC or any combination thereof. Network 104 is also based on a corresponding communication protocol while transmitting data, for instance, the HTTP communication protocol will be the basis when a webpage browser receives business codes corresponding to the webpage, and the Websocket communication protocol can be the basis when a mobile application program receives business codes.

Date Recue/Date Received 2022-03-04

[0058] Business system 106 can include one or more server(s), for example, what is shown in Fig. 1-1 is the case in which business system 106 includes two servers, namely server 1062 and server 1064, but the present application makes no restriction to the number of server(s), as more or less server(s) can as well be included. Each server can be embodied as an independent server or a server cluster consisting of a plurality of servers.

[0059] The method of capturing an Http redirecting status code provided by the present application is further applicable to the application environment as shown in Fig. 1-2. This application environment can further include gateway 108 besides terminal 102, network 104 and business system 106 as shown in Fig. 1-1. Gateway 108 is deployed at a gateway layer, and the gateway layer is usually the layer previous to the WEB server.
As a computer equipment, gateway 108 uniformly performs transformation of response messages with respect to redirected responses of the business system to applets operative on various terminals, so as to ensure that the applets operative on various terminals can respond to redirecting status codes of the business system. In addition, there can as well be plural business systems 106. The plural business systems 106 correspond to the same and single gateway.

[0060] In one embodiment, as shown in Fig. 2, there is provided a method of capturing an Http redirecting status code, and the method is explained with an example of its being applied to the gateway in Fig. 1-2, to comprise the following steps.

[0061] Step 202 - obtaining a first status code, wherein the first status code is a status code in a response header of a first response message, and the first response message is a response message returned by a business system after an Http request has been initiated to the business system.

[0062] The status code here usually means a three-digit code allocated to a received request (such Date Recue/Date Received 2022-03-04 as webpage clicking), and is usually an Http status code that is a three-digit code used to express the hypertext transfer protocol response status of a webpage server.
Here, the Http request is for requesting a first response message.

[0063] Specifically, after the terminal (or in other words, an applet operative on the terminal) has sent a business request to the business system, the business system obtains a first response message according to the business request; the gateway initiates an Http request to the business system to obtain the first response message, and obtains a status code, namely the first status code, in the response header of the first response message after having obtained the first response message.

[0064] Step 204 - constructing a second response message according to a preset message protocol format and the first status code when the first status code is a redirecting status code, wherein the first status code is carried in a message body of the second response message.

[0065] Here, the redirecting status code usually indicates any status code relevant to redirection in Http status codes, such as status codes 301, 302, 303, and 307. By redirecting is meant to relocate various network requests to other locations by various methods, for example, webpage redirecting or domain name redirecting.

[0066] The message protocol format here is the format of a message protocol previously agreed upon by the gateway and downstream receivers, and the message protocol format at least includes the configuration mode of the first status code.

[0067] Specifically, the gateway firstly judges whether the first status code is a redirecting status code, if yes, constructs the second response message according to the preset message protocol format and the first status code, wherein the first status code is carried in a message body of the second response message. As required, the process of judging whether the first status code is a redirecting status code can also be completed via any Date Recue/Date Received 2022-03-04 other equipment, and the gateway obtains the judging result.

[0068] Step 206 - returning the second response message, wherein the second response is for instructing a receiver to obtain the redirecting status code according to the message protocol format.

[0069] Specifically, the gateway returns the second response message to the terminal (or in other words, an applet operative on the terminal). In the aforementioned method of capturing an Http redirecting status code, a first status code is obtained, wherein the first status code is a status code in a response header of a first response message, the first response message is an Http response message returned by a business system after an Http request has been initiated to the business system. A second response message is constructed according to a preset message protocol format and the first status code when the first status code is a redirecting status code, wherein the first status code is carried in a message body of the second response message. The second response message is returned, wherein the second response is for instructing a receiver to obtain the redirecting status code according to the message protocol format. In this embodiment, response message transformation is performed according to a preset message protocol format, so that the redirecting status code originally not supported by the receiver is carried in the message body of the second response message, whereby the second response message is obtained, and it is possible for the receiver (such as an applet end) to obtain the redirecting status code according to the message protocol format. Thusly, it is no longer required to invoke the interface of the server end to judge the login status of the user, and this on the one hand reduces the frequency for invoking the interface to judge the login status of the user, and on the other hand also reduces response delay and enhances user experience.

[0070] In one embodiment, the message header of the second response message carries therein a second status code, wherein the second status code is a status code supported by the receiver and different from the first status code.

Date Recue/Date Received 2022-03-04

[0071] Here, the second status code can be status code 200 that represents status codes having successfully processed requests. As required, the second status code can also be any status code other than status code 200, for example, status code 2xx.

[0072] In one embodiment, as shown in Fig. 3, the step of constructing a second response message according to a preset message protocol format and the first status code when the first status code is a redirecting status code can include the following steps.

[0073] Step 302 - obtaining network location information in the response header of the first response message when the first status code is a redirecting status code.

[0074] Here, the network location information can also be referred to as webpage address information that is a standard resource address on the internet. The network location information is usually the location in the response header of the response message.

[0075] Specifically, the gateway first judges whether the first status code is a redirecting status code, if yes, then obtains the network location information in the response header of the first response message.

[0076] Step 304 - constructing the second response message according to the preset message protocol format, the first status code and the network location information, wherein the message body of the second response message further carries therein the network location information.

[0077] Here, the message protocol format further includes the configuration mode of the message protocol format. The network location information serves as the redirecting webpage address information (redirectUr1).

Date Recue/Date Received 2022-03-04

[0078] Specifically, the gateway can configure the first status code and the network location information in the message body of the second response message according to the preset message protocol format. Generally, it is possible to configure the first status code and the network location information in the same and single message body, and it is also possible, with respect to the circumstance in which the same and single response message includes a plurality of message bodies, to configure the first status code and the network location information in different message bodies.

[0079] Since the message body of the second response message further carries therein the network location information, use of the solution according to this embodiment facilitates the terminal (or in other words, an applet operative on the terminal) to initiate invoking for modifying the network location information (namely redirecting).

[0080] Since consideration is given to the fact that it is generally required to carry the cookie of the previous request while requesting redirection, in one embodiment, as shown in Fig. 4, the step of constructing a second response message according to a preset message protocol format and the first status code when the first status code is a redirecting status code can include the following steps.

[0081] Step 402 - obtaining network location information in the response header of the first response message and Cookie data in the response header of the first response message when the first status code is a redirecting status code.

[0082] Cookie, whose plural form of Cookies is sometimes also used, means (usually encrypted) data stored by some websites on local user terminals to distinguish user identifications and perform session tracking.

[0083] Step 404 - constructing the second response message according to the preset message protocol format, the first status code, the network location information and the Cookie Date Recue/Date Received 2022-03-04 data, wherein the message body of the second response message further carries therein the network location information and the Cookie data.

[0084] Use of the solution according to this embodiment further facilitates the terminal (or in other words, an applet operative on the terminal) to initiate invoking for modifying the network location information.

[0085] In one embodiment, as shown in Fig. 5, there is provided a method of capturing an Hap redirecting status code, and the method is explained with an example of its being applied to the gateway in Fig. 1, to comprise the following steps.

[0086] Step 502 - screening the received response message according to preset user agent screening rule or/and description information screening rule.

[0087] Both the user agent screening rule and the description information screening rule can be set according to practical requirements. For instance, a user agent identification collection is set, if the user agent identification to which the received response message corresponds is one in the user agent identification collection, it is determined that the user agent screening rule is satisfied. For instance, it is also possible to set a description information collection, if the description information to which the received response message corresponds is matched with any piece of description information in the description information collection, it is determined that the description information screening rule is satisfied.

[0088] Step 504 - taking the received response message as the first response message when the received response message satisfies the user agent screening rule or/and the description information screening rule.

[0089] Step 506 - obtaining a first status code, wherein the first status code is a status code in a Date Recue/Date Received 2022-03-04 response header of a first response message, and the first response message is a response message returned by a business system after an Http request has been initiated to the business system.

[0090] Step 508 - constructing a second response message according to a preset message protocol format and the first status code when the first status code is a redirecting status code, wherein the first status code is carried in a message body of the second response message.

[0091] Step 510 - returning the second response message, wherein the second response is for instructing a receiver to obtain the redirecting status code according to the message protocol format.

[0092] Reference can be correspondingly made to the descriptions to the aforementioned steps 202, 204 and 206 for steps 506, 508 and 510 in this embodiment, and no repetition is redundantly made in this context.

[0093] The received response message is filtered in this embodiment, whereby the flow consumed by the applet can be economized.

[0094] In one embodiment, the method of capturing an Http redirecting status code according to the present application can further include the step of returning the first response message when the first status code is a non-redirecting status code.

[0095] Here, the non-redirecting status code means a status code that is irrelevant to redirection.

[0096] In this embodiment, when the first status code is a non-redirecting status code, the first response message is not modified, but directly returned to the receiver. It suffices for the receiver to process the directly returned first response message according to the original business processing logic.

Date Recue/Date Received 2022-03-04

[0097] As should be noted, all of the aforementioned embodiments are exemplified by applying the method of capturing an Http redirecting status code of the present application to a gateway, and are described with the receiver being a terminal, on which is operative an applet application that obtains the redirecting status codes according to the message protocol format. However, as practically required, it is also possible to apply the method of capturing an Http redirecting status code in the aforementioned embodiments to the business system or one or more server(s) of the business system in Fig. 1-1 or Fig. 1-2, that is to say, the execution subject of the various steps in the aforementioned various embodiments is the business system or one or more server(s) of the business system.

[0098] As for the application to a gateway, the gateway can be enabled to uniformly perform transformation of response messages with respect to redirected responses of the various applets, so as to ensure that the applets operative on various terminals can respond to redirecting status codes of the business system. This on the one hand makes it unnecessary to invoke the interface of the server end to judge the login status of the user, so there is no intrusion to the business on the server end, and on the other hand also unnecessary to separately configure each server to realize transformation of redirected responses, so configuration cost can be saved.

[0099] Based on the method of capturing an Http redirecting status code in the aforementioned embodiments, in one embodiment, as shown in Fig. 6, there is provided a method of capturing an Http redirecting status code, and the method is explained with an example of its being applied to the terminal, on which an applet application is operative, in Fig. 1-1 or Fig. 1-2, to comprise the following steps:

[0100] Step 602 - receiving a response message; and

[0101] Step 604 - obtaining, when it is determined that the received response message is a second response message, a redirecting status code carried in a message body of the second response message according to a preset message protocol format, wherein the redirecting Date Recue/Date Received 2022-03-04 status code is a first status code, and the second response message is constructed according to the message protocol format and the first status code.

[0102] In addition, when it is determined that the received response message is a first response message, processing is performed according to the original logic by which the applet application processes the first response message.

[0103] When the message body of the second response message further carries therein the network location information, a redirecting request can be initiated according to the network location information; when the message body of the second response message further carries therein the Cookie data, the response header of the initiated redirecting request carries the Cookie data.

[0104] As for a specific definition to the method of capturing an Http redirecting status code at the terminal side, reference can be made to the aforementioned definition to the method of capturing an Http redirecting status code at the gateway side, while no mention is made thereto in this context.

[0105] To facilitate comprehension of the solution of the present invention, explanation is made below with an example of interaction between the gateway and an applet application (hereinafter referred to as the applet end).

[0106] The message protocol format in this embodiment is: {"code":
"redirecting status code", "redirectUr1": "Location", "cookie": "Cookie"}, a protocol is made at the same time, when the downstream business system returns the redirecting status code, it is constrained that the returning result be a message protocol of the json format, namely the message protocol format, in which json is a lightweight data interchange format.

[0107] The code in the message protocol format is a status code (Status), such as 301, 302, inside Date Recue/Date Received 2022-03-04 the response header that requests the business system to come up with redirection. The redirectUrl is the network location information (Location) inside the response header that requests the business system to come up with redirection. The cookie is the Cookie inside the response header that requests the business system to come up with redirection.

[0108] The applet unified gateway (equivalent to the aforementioned gateway) can be established by means of OpenResty(nginx+lua), the gateway layer is used by the applet, the flow of the applet can be restricted at the unified access layer through user agent (userAgent) and description information (refer) to arrive at the applet unified gateway, the gateway layer uses an httpc library to invoke the downstream business system interface and analyzes to obtain the response header of the business system interface, and returns the status code, the network location information and the Cookie inside the response header into the message body of the response message according to the aforementioned message protocol format when the response code inside the response header is a redirecting status code, wherein the status code given to the response message is 200. The code is a response status code marking the actual business, redirectUrl is Location inside the redirecting response header to facilitate the applet to initiate invoking of the URL for next time, and cookie is the cookie inside the response header of the first request, because the cookie of the previous request should be carried when redirecting (redirectUrl) is requested.

[0109] The applet end learns through the code in the returned message of json format that the business system actually returns a status code, finds that the status code is a redirecting status code, then places the Cookie inside the message of json format into the request header, requests the redirectUrl address inside json, and hence obtains returned business data.

[0110] The gateway layer can employ httpc of nginx+lua to initiate the http request of the business system, as shown in Fig. 7, the method of capturing an Http redirecting status Date Recue/Date Received 2022-03-04 code in this embodiment can include the following steps.

[0111] Step 702 ¨ by the gateway judging whether the status code in the response message of the business system is a redirecting status code, if yes, entering step 704, if not, entering step 706.

[0112] Here, the response message of the business system corresponds to the aforementioned first message. Specifically, the applet end sends a business request to the business system, the business system obtains a response message according to the business request, and the gateway requests the response message from the business system.
Specifically, the gateway can use httpclient to invoke interface URL of the business system. The gateway layer obtains the status code inside the response header of the response message of the business system, and judges whether it is a status code relevant to redirection (301, 302, 303, 307, etc.).

[0113] Step 704 ¨ by the gateway obtaining the status code, network location information and Cookie inside the response header of the response message of the business system, and constructing, on basis of the corresponding values, and returning a message with status code 200 according to an agreed message protocol format.

[0114] Specifically, it is possible to obtain the status code (Status), network location information (Location) and Cookie inside the response header of the response message of the business system, to construct a message with status code 200: {"code": "redirecting status code", "redirectUr1": "Location", "cookie"Cookie"}, based on the corresponding values of the status code, network location information and Cookie, according to an agreed protocol format, and to return the message.

[0115] Step 706¨ by the gateway returning the response message of the business system.
Date Recue/Date Received 2022-03-04

[0116] Specifically, if the status code is a non-redirecting status code, the gateway returns the response message of the business system.

[0117] Step 708 ¨ at the applet end receiving the response message sent by the gateway, and analyzing response header information of the received response message.

[0118] There are two analyzing results: 1. normal non-redirected response; and 2. redirected response of the original business processed by the gateway, namely a redirecting protocol, with the format: {"code": "redirecting status code", "redirectUr1":
"Location", "cookie"Cookie"}.

[0119] Step 710 ¨ when a non-redirected response message is received at the applet end, processing according to the business processing logic to which the response message corresponds.

[0120] Step 712¨ when a redirected response message is received at the applet end, initiating a redirecting request according to the network location information in the message body of the response message.

[0121] The cookie is disposed in the request header of the redirecting request, and a redirecting request is initiated with the network location information in the message body of the response message as the new address information.

[0122] A set of protocols is stipulated to solve the problem that the applet does not support the http redirecting status code. A gateway layer established by means of OpenResty(nginx+lua) is employed to capture the http redirecting status code, the constraint protocol {"code": "redirecting status code", "redirectUr1":
"Location", "cookie"Cookie"} is returned, the httpc library of lua can be employed to analyze Status, Location, and Cookie data in the response header of the http protocol interface, and the Date Recue/Date Received 2022-03-04 result is returned according to the constraint protocol. By using this protocol, the redirected response of the business system is transformed to a response of status code 200 through processing by the gateway layer.
