Description

Page communication method and device

Technical Field

The disclosure relates to the field of computer technology, and in particular, to a method and a device for page communication.

Background

Iframe is a hypertext markup language (HyperText Markup Language, HTML) tag by which one page can be embedded into another as a presentation area in one page. Alternatively, pages with different domain names may also nest with each other when a preset constraint is reached. For example, in the page of the site a, the page of the site B may be embedded into the page of the site B through the iframe, and then the page of the site B is called an iframe page (also called a child page), and the page of the site a is a parent page corresponding to the iframe page. In the parent page of site a, a cross-domain call may be initiated to site B.

In the prior art, when a parent page and a child page communicate with each other, an asynchronous message delivery function (postMessage) application programming interface (Application Programming Interface, API) is typically used for communication.

However, since the postMessage is returned immediately after the message to be sent is put into the queue, and then the next task is continuously executed, regardless of whether other programs process the message, when the parent page initiates the service to the child page, communication between the parent page and the child page is performed based on the postMessage API, and therefore, an immediate monitoring mode needs to be started, that is, a server specially used for monitoring is required to be set immediately, all data after the returned value of the postMessage is received is monitored, then the data is screened, matched data is screened out, and because a large amount of irrelevant data exists in all monitored data, communication is performed simply based on the postMessage API, so that the efficiency of page communication of the data is greatly reduced, and meanwhile, because the page of the iframe cannot timely sense the abnormal condition of the communication counterpart, a security risk exists.

Therefore, there is a need to devise a new approach to solve the above-mentioned problems.

Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings.

With the complexity of the web page structure, the application scene of embedding another page in one page by adopting the iframe technology is more and more common, and the communication requirement between the parent page and the child page is generated.

Fig. 1 illustrates an application scenario of a page communication provided in an embodiment of the present disclosure, and referring to fig. 1, a terminal device 100 presents a parent page 101 and a plurality of sub-pages 102 that perform page communication with the parent page 101 in an operation interface of a browser, where a user may trigger page communication for the sub-pages 102 in the parent page 101.

Referring to fig. 2A, in the embodiment of the present disclosure, a specific flow of page communication performed by a terminal device is as follows:

step 200: and when the terminal equipment determines that the preset triggering condition is met, a communication channel is established between the first page and the second page.

In the embodiment of the present disclosure, the terminal device determines that the preset trigger condition is met, which may be, but is not limited to, two modes:

in mode 1, when the terminal device receives a communication request for a second page triggered in a first page, it is determined that a preset trigger condition is met.

In specific implementation, referring to fig. 1, if the first page is a parent page and the second page is a child page, when the terminal device receives a communication request for the child page triggered in the parent page, it is determined that a preset triggering condition is met; if the first page is a child page and the second page is a parent page, when the terminal equipment receives a communication request aiming at the parent page and triggered in the child page, the terminal equipment determines that a preset triggering condition is met. Thus, whether the initiator initiating the communication request is a parent page or a child page, a thread that establishes a communication channel between the parent page and the child page can be initiated to establish a reliable communication channel for the communication request between the parent page and the child page.

In the mode 2, when the terminal equipment receives a communication request triggered by a preset thread, the terminal equipment determines that a preset triggering condition is met.

In specific implementation, the terminal device may correspondingly establish a communication channel between the first page and the second page according to the received communication request triggered by the preset thread.

Thus, when the terminal equipment receives the trigger condition meeting the preset condition, a reliable communication channel can be established between the first page and the second page, so that the safety communication requirement between the first page and the second page can be met.

In the embodiment of the present disclosure, the following description will be given by taking only a scenario in which a communication channel is established between a first page and a second page when a terminal device receives a communication request for a child page triggered in a parent page as an example. Establishing a communication channel between a first page and a second page aiming at the terminal equipment receiving a communication request for a parent page triggered in a child page; the specific implementation of establishing a communication channel between the first page and the second page when the terminal device receives the communication request triggered by the preset thread is similar, and will not be described herein.

Referring to fig. 2B, the terminal device may present a parent page in a browser in an operation interface, where at least a navigation button is presented in the parent page, and when the user clicks the navigation button, the terminal device determines that a communication request for the second page is triggered by the user in the first page, and then the terminal device responds to the communication request to establish a communication channel between the first page and the second page.

Optionally, referring to fig. 3, in an embodiment of the present disclosure, the terminal device may set up a communication channel between the first page and the second page by adopting the following steps:

step 2001: the terminal device receives a communication request for a second page triggered in the first page.

In the embodiment of the disclosure, referring to fig. 2B, the terminal device receives a navigation button clicked by a user in a parent page, and correspondingly triggers a communication request for a child page.

Step 2002: the terminal equipment generates a creation channel message corresponding to the communication request, wherein the creation channel message at least comprises an attribute identifier of the creation message.

In the embodiment of the disclosure, referring to fig. 2B, according to a communication request triggered by a user on a parent page, a terminal device correspondingly generates a creation channel message carrying at least a creation message attribute identifier, where the creation message attribute identifier is used to make the terminal device verify a creation response message returned by a child page.

Alternatively, the create channel message may be a handshake (handshake) type message.

Alternatively, the handlegram type message may be compiled using a lightweight data exchange format (JavaScript Object Notation, json) structure, may be a type field in a custom json structure, and the carried create message attribute identifier may be a cid field.

For example, referring to fig. 4, taking a first page as a parent page and a second page as a child page as an example.

Assume that a terminal device receives a communication request for a child page triggered at a parent page.

Then, the terminal device generates a corresponding creation channel message based on the communication request, and the creation channel message at least contains the creation message attribute identifier.

Assuming that the create channel message (handleshake) is compiled by adopting a json structure, and the attribute identifier of the create message can be a cid field corresponding to a type field in the json structure, then the corresponding create channel message can be:

step 2003: the terminal device sends the create channel message to the second page through the postmessage API.

In the embodiment of the disclosure, the postmessage () method allows scripts from different sources to effectively communicate in an asynchronous manner, so that cross-text document, multi-window and cross-domain message passing can be realized, and therefore, the terminal device can send the generated creation channel message to a second page (such as a sub page) through a postmessage API.

Step 2004: the terminal device sets an initiator for the reception of the creation response message and starts a timer.

In the embodiment of the disclosure, the terminal device sets a timer for receiving the creation response message and starts the timer while sending the creation channel message to the second page, wherein the timer is used for reducing the resource of the terminal device and preventing program paralysis. In this way, when the terminal equipment establishes a communication channel between the first page and the second page, by setting the timer, normal operation of a thread for establishing the communication channel can be ensured, and program paralysis and waste of network resources caused by endless loop are avoided.

Step 2005: the terminal device determines whether a creation response message carrying the attribute identifier of the creation message is received, if yes, step 2009 is executed, otherwise step 2006 is executed.

In the embodiment of the disclosure, the terminal device monitors a creation response message returned by the second page, wherein the creation response message carries an attribute identifier of the creation message.

Optionally, the terminal device further determines whether the creation response message carries the creation message attribute identifier in the corresponding creation channel message by determining whether the creation response message is received, if the terminal device receives the creation response message, and when determining that the creation response message carrying the creation message attribute identifier is received, performs step 2009. Accordingly, if the terminal device does not receive the creation response message, step 2006 is performed.

Optionally, after receiving the creation response message, the terminal device may first search for a source (origin) attribute of the creation response message, and then determine, based on the origin attribute, that the creation response message is returned by the second page, so that by verifying the source of the creation response message, an abnormal situation of the second page can be timely perceived, and the second page is effectively prevented from being accidentally redirected to unsafe environments such as a forged page, thereby ensuring communication security between the first page and the second page.

For example, referring to fig. 5, the first page is still used as a parent page, and the second page is used as a child page.

It is assumed that the terminal device determines that a creation response message carrying the attribute identifier of the creation message is received, and that the creation response message is also compiled using a json structure.

Then, corresponding to the creation response message of the handle-ack type returned by the terminal device from the sub page received by the postmessage API, where the creation response message carries the attribute identifier of the creation message, and the corresponding creation response message may be:

step 2006: the terminal device determines whether the timer has timed out based on the initiator set for the reception creation response message, and if so, executes step 2007, otherwise, returns to execute step 2005.

In the embodiment of the present disclosure, the terminal device monitors the creation response message returned by the second page, and if the terminal device determines that the creation response message carrying the attribute identifier of the creation message is not received, and the timer set for receiving the creation response message has expired, step 2007 is executed.

Step 2007: the terminal device determines whether the number of times of judgment exceeds the set threshold, if so, performs step 2010, otherwise, performs step 2008.

In the embodiment of the disclosure, if the terminal device determines that the creation response message carrying the attribute identifier of the creation message is not received and the timer set for receiving the creation response message has timed out, determining whether the number of judgment exceeds a set threshold, wherein the set threshold can be customized according to the needs of a user.

In this way, when the terminal equipment establishes a communication channel between the first page and the second page, the normal operation of the thread for establishing the communication channel can be ensured by setting a set threshold value for the judgment times, so that program paralysis caused by endless loop is avoided;

step 2008: the terminal device updates the creation message attribute identifier, and returns to step 2002.

In the embodiment of the disclosure, the terminal device updates the created message attribute identifier, and then returns to execute step 2002 to restart a further flow of establishing a communication channel.

Therefore, when the terminal equipment establishes a communication channel between the first page and the second page, the timeliness of the established communication channel can be ensured by updating the established message attribute identifier, so that timely and efficient communication between the first page and the second page is ensured.

Step 2009: the terminal equipment determines that the establishment of the communication channel between the first page and the second page is completed.

In the embodiment of the disclosure, if the terminal device determines that the creation response message carrying the attribute identifier of the creation message is received, and that the timer set for receiving the creation response message is not overtime, and that the number of judgment times does not exceed the set threshold, it is determined that the establishment of the communication channel between the first page and the second page is completed.

Step 2010: the terminal device determines that the communication channel between the first page and the second page fails to be established.

In the embodiment of the disclosure, if the terminal device determines that the creation response message carrying the attribute identifier of the creation message is not received and determines that the number of judgment times exceeds the set threshold, it is determined that the establishment of the communication channel between the first page and the second page fails.

Step 210: the terminal equipment responds to a service request triggered by a service to be presented in a first page, generates a loading request message corresponding to the service request, and sends the loading request message to a second page through a communication channel, so that the second page loads service data of the service to be presented based on the loading request message, wherein the loading request message at least comprises a service identifier of the service to be presented and a loading message attribute identifier.

In the embodiment of the present disclosure, the terminal device establishes a communication channel between the first page and the second page by executing step 2001-step 2009.

In this disclosure embodiment, referring to fig. 6, a terminal device may present a parent page in a browser in an operation interface, where at least a to-be-presented service button is presented in the parent page, and when a user clicks the to-be-presented service button, the terminal device determines that a service request triggered for the to-be-presented service is triggered in a first page by the user, and then the terminal device responds to the service request, and generates a loading request message corresponding to the service request. And then, sending a loading request to a second page through a communication channel, wherein the loading request message at least comprises the service type of the service to be presented and the attribute identifier of the loading message.

Optionally, the service identifier of the service to be presented is used for enabling the second page to load service data of the service to be presented based on the loading request information, and the loading message attribute identifier is used for searching the corresponding loading request message based on the loading message attribute identifier carried by the loading response message when the terminal device receives the loading response message returned by the second page.

Optionally, the attribute identifier of the loading message contained in the loading request message is uniquely set and fixed for the corresponding service to be presented.

For example, referring to fig. 7, the first page is still taken as a parent page, and the second page is taken as a child page.

It is assumed that the terminal device responds to a service request for a child page triggered at a parent page.

And then, the terminal equipment generates a corresponding loading request message based on the service request of the service to be presented, wherein the loading request message at least comprises the service identifier of the service to be presented and the loading message attribute identifier.

And assuming that the loading request message is compiled by adopting a json structure, the type field in the corresponding json structure is message, the loading message attribute identifier can be mid field, meanwhile, the created message attribute identifier carrying the communication channel can be cid field, and the corresponding message load of the service to be presented is payload.

Then the corresponding load request message may be:

optionally, when executing step 210, if a plurality of corresponding service requests are triggered for a plurality of services to be presented in the first page, the terminal device executes the following steps:

A. the terminal equipment responds to corresponding service requests triggered by a plurality of services to be presented in a first page, and correspondingly generates respective loading request messages of the service requests, wherein each loading request message at least comprises a service identifier of the corresponding service to be presented and a corresponding loading message attribute identifier.

In the embodiment of the present disclosure, if service requests of the to-be-presented services of the plurality of second pages are triggered in the first page, the terminal device may respectively respond to the service requests of the plurality of to-be-presented services, and generate loading request messages corresponding to the plurality of service requests, where each loading request message at least includes a service identifier of the corresponding to-be-presented service and a corresponding loading message attribute identifier.

B. The terminal equipment constructs a message set based on the plurality of loading request messages, and sends the plurality of loading request messages to a plurality of second pages through communication channels respectively, so that the plurality of second pages load corresponding service data of the service to be presented based on the corresponding loading request messages respectively.

In the embodiment of the disclosure, after generating the corresponding loading request message, the terminal device constructs a corresponding message set, and sends the multiple loading request messages to the multiple second pages through communication channels, so that the multiple second pages load the corresponding service data of the service to be presented based on the corresponding loading request messages, respectively, wherein the message set is used for searching the corresponding loading request message based on the loading message attribute identifier carried by the loading response message when the terminal device receives the loading response message returned by the multiple second pages, so that the terminal device does not need to be specially allocated with a server or a device for monitoring, and further the purposes of saving resources and optimizing the network architecture can be achieved.

C. And each time the terminal equipment receives a loading response message returned by the second page, removing the corresponding loading request message from the message set based on the loading message attribute identifier carried by the loading response message.

In the embodiment of the disclosure, after a plurality of loading request messages are sent to a second page through a communication channel, the terminal device receives loading response messages returned by the second page one by one, and then the terminal device obtains carried loading message attribute identifiers from the loading response messages after receiving the loading response messages returned by one second page, and then searches for corresponding loading request messages in a message set based on the loading message attribute identifiers, and removes the corresponding loading request messages from the message set.

Optionally, when removing the message set from the corresponding loading request message, the terminal device may call a corresponding callback function (callback), and return a corresponding notification message to the first page, so as to implement an asynchronous calling method, where the notification message is used to notify the first page that the loading response message returned by the second page has been received for the service to be presented.

Optionally, the attribute identifier of the loading message carried by the loading response message is uniquely set and fixed for the corresponding service to be presented.

Optionally, the loading response message further carries a creation message attribute identifier of the corresponding communication channel, where the creation message attribute identifier is used for verifying, by the terminal device, that the second page is returned by the second page through the pre-established communication channel.

Optionally, after receiving the loading response message, the terminal device may perform message verification on the obtained loading response message by adopting the following operations:

in operation a, first, the terminal device obtains an origin attribute in the load response message, and then, based on the origin attribute, determines whether the load response message is returned by the second page. If the verification is passed, determining that the loading response message is returned by the second page, and determining that the second page is an iframe page conforming to the expectation, thereby avoiding the second page of the iframe from being tampered accidentally; if the verification is passed, the loading response message is determined not to be returned by the second page, the terminal equipment can timely sense the abnormal condition of the second page, so that further communication between the first page and the maliciously tampered second page is interrupted.

And b, because the loading response message returned by the second page received by the terminal equipment carries the corresponding creation message attribute identifier, the terminal equipment can acquire the creation message attribute identifier, and determine that the loading response message is returned by the second page through the communication channel based on the creation message attribute identifier, thereby ensuring the safety of communication between the first page and the second page.

For example, referring to fig. 8, the first page is still taken as a parent page, and the second page is taken as a child page.

The terminal equipment receives the loading response message returned from the sub-page, and the loading response message is also compiled by adopting a json structure, wherein the loading response message carries the loading message attribute identification.

Then, the loading response message that the terminal device receives the sub-page return may be:
