It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," or "having," and any variations thereof, are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For convenience of understanding, a detailed flow of an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a method for previewing edited content of a web page in real time in an embodiment of the present invention includes:
101. acquiring edit data, and sending the edit data to a preset data model through a preset program interface function and a message sending window;
it is to be understood that the executing entity of the present invention may be a device for previewing the edited content of the web page in real time, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.
The editing data comprises editing content generated by editing in a preset editing page and an address of a data sending end corresponding to the preset editing page. The method comprises the steps that a user edits an editing page, a server takes an editing end where the editing page is located as a data sending end, namely a communication initiating end, calls a preset program interface function to open a preset message sending window, the preset program interface function is an application program interface function PostMessage, editing data are sent to the preset message window, the preset message sending window can be a floating frame iframe, the editing data comprise editing contents generated by the user through editing the preset editing page and an address of the data sending end, and the preset message sending window transmits the editing data to a preset data model in a parallel communication mode through a full-duplex communication channel. The data sending end is pre-created with a message monitor to monitor the feedback information after the sent edited data, and timely learn whether the edited data is sent successfully or not and whether the data model receives the edited data successfully or not, so that the data can be timely resent when the sending fails or the receiving fails to ensure the sending and the receiving of the data.
102. Acquiring and verifying whether a uniform resource identifier of the edited data is legal or not through an event monitor in the data model;
the data model is used as a data receiving end for sending data by a data sending end, the server invokes an event listener in the data model to monitor, when the event listener monitors that a message (namely, edit data) is sent, the event listener receives the message and extracts a Uniform Resource Identifier (URI) of the message, namely, the URI of the data sending end, and whether the URI of the message is legal or not is verified so as to verify whether the message is from a credible address or not. The URI can be verified to be legal or not through a regular expression or a static mode Uri. When the uniform resource identifier of the edited data is illegal, the server feeds back verification information to the sending end, receives the manually corrected edited data sent by the sending end, calls a preset message queue interface to update the edited data to a database in a data model, and triggers an updating instruction; or when the uniform resource identifier of the editing data is illegal, the server acquires the corresponding stored correction rule, corrects the editing data according to the correction rule, updates the corrected editing data to a database in the data model, and triggers an update instruction.
103. When the uniform resource identifiers of the edited data conform to the method, calling a preset message queue interface to update the edited data to a database in a data model and triggering an update instruction;
when the uniform resource identifiers of the edited data meet the law, an event listener in the data model calls a preset message queue interface dispatch to submit the edited data to an Action object, the Action object is used as a parameter to send the edited data to a database in the data model, when the edited data is updated to the database in the data model, an updating instruction is started to prompt the preset view model data model to store new data, and the preset view model needs to call a preset page model to respond and process the edited data. The multitask concurrent operation is realized through the preset message queue interface dispatch, the background server and the background interface are reduced, and resource waste, server congestion and server crash caused by continuously polling data to update pages are avoided.
104. Receiving an updating instruction through a preset view model, and starting a preset page model according to the updating instruction;
in the data drive, the data Model and the preset page Model View cannot be communicated directly, so that the communication between the data Model and the preset page Model View needs to be realized through the preset View Model View. When updating data (namely editing contents stored in an editing page) in the data model triggers an updating instruction, the preset View model ViewModel can monitor the updating and storing of the data in the data model (namely receiving the updating instruction) and timely inform the preset page model View to make corresponding and modification. Similarly, when there is an event trigger in the preset page Model View, the preset View Model can also monitor the event trigger of the preset page Model View and notify the data Model to respond. The preset view model ViewModel is equivalent to an observer, monitors the actions of the two parties and informs the other party of performing corresponding operations in time.
105. And rendering the editing data in the data model to a preset preview page through the preset page model.
When the preset page model ViewModel monitors the data model to update and store the data (namely, receives an update instruction), the preset preview page model View is started, the edited content generated by the edited page is synchronously displayed on the preset preview page on the same interface with the edited page, wherein, the vm is called by the mount component function to generate the virtual Node, and then the virtual Node is combined to instantiate an observer Watcher with rendering function, calling an update component function in a callback function of the Watcher watch, finally calling a vm update function to update a DOM node, realizing that the edited data is rendered on a preset preview page, so as to achieve the effect that the data can be modified and presented on the preset preview page without modification through the DOM node by modifying the data logic, through the PostMessage and the data driving, the edited content of the edited page can be directly displayed on the preview page in real time without refreshing the page.
In the embodiment of the invention, the data transmission, the data updating and the real-time synchronization between the editing page and the previewing page are carried out by adopting the preset program interface function, the message sending window, the preset message queue interface and the preset page model, so that the effect of previewing the edited content of the webpage immediately after editing is realized.
Referring to fig. 2, another embodiment of the method for previewing the edited content of the web page in real time according to the embodiment of the present invention includes:
201. acquiring edit data, and sending the edit data to a preset data model through a preset program interface function and a message sending window;
specifically, the server acquires edit data, and sends the edit data to a preset data model through a preset program interface function and a message sending window, and the method includes: acquiring edit data, and performing serialization processing and deserialization processing on the edit data to obtain a data conversion object of the edit data; extracting key values of data conversion objects; calling a preset program interface function to assign the key value to a preset parameter, and sending the edited data to a preset message sending window through the preset parameter, wherein the preset parameter is used for indicating a pointer pointing to any type of object; and extracting target data corresponding to the key value from the edited data, and transmitting the target data to the data model through the message sending window.
For example: a user edits on an editing page to generate editing content, a server acquires the editing content and a sending end address corresponding to the editing content to obtain editing data, the editing data is stored in a file or other storage devices in a byte sequence mode (serialization processing) to obtain sequence data, deserialization processing is carried out on the sequence data to reconstruct the byte sequence into an object, so that a data conversion object value corresponding to each editing data is generated, a key value key corresponding to each value is extracted, a Postmessage function is called to assign the key value key corresponding to each value to a corresponding wParam parameter or IPAram parameter, the editing data is transmitted to a preset message sending window in a message mode through the wParam parameter or the IPAram parameter, the message sending window receives the message, and then target data which is in accordance with the data type stored by a data model is extracted from the message through the key value, and sending the extracted target data into the data model. The key value comprises a key value with an integer data type; the preset parameter may be a handle wParam of a window or a control, or may be a pointer IParam pointing to data in the memory. The editing data is transferred to a preset data model by adopting a pointer pointing to any type of object, so that the effect of sending any type of data to the control by using the PostMessage function of the application program interface is achieved.
202. Acquiring and verifying whether a uniform resource identifier of the edited data is legal or not through an event monitor in the data model;
specifically, the server obtains and verifies whether the uniform resource identifier of the edited data is legal through an event listener in the data model, including: acquiring uniform resource identifiers of the edited data and character string formats corresponding to the uniform resource identifiers through an event listener in the data model; judging whether the character string format is correct or not; if the character string format is correct, judging whether the uniform resource identifier exists in a preset uniform resource identifier table or not, wherein the uniform resource identifier table comprises legal uniform resource identifiers; if the uniform resource identifier exists in a preset uniform resource identifier table, judging that the uniform resource identifiers of the editing data conform to the method.
When the server judges that the character string format is incorrect through an event monitor in the data model, the server feeds back edit data and judgment information corresponding to the character string format to the sending end, receives edit data sent by the sending end and obtained by manually correcting the character string format, and traverses a preset uniform resource identifier table according to a uniform resource identifier of the edit data obtained by correcting; or when the server judges that the character string format is incorrect, acquiring a corresponding stored format correction rule, correcting the edit data according to the format correction rule, and traversing a preset uniform resource identifier table according to the uniform resource identifier of the corrected edit data. If the uniform resource identifier does not exist in the stored uniform resource identifier table, the uniform resource identifier of the editing data is judged to be illegal. The uniform resource identifier is verified in the first step by judging whether the character string format corresponding to the uniform resource identifier is correct or not, and then the uniform resource identifier with the correct character string format is matched and analyzed with a stored uniform resource identifier table, so that the uniform resource identifier conformity and safety are effectively judged. The stored uniform resource identifier table may be a valid historically used uniform resource identifier obtained from an operation log or other information of the server, and the credibility of the uniform resource identifier is accurately analyzed by judging that the uniform resource identifier is a credible historically used uniform resource identifier.
203. When the uniform resource identifiers of the edited data conform to the method, calling a preset message queue interface to update the edited data to a database in a data model and triggering an update instruction;
specifically, when the uniform resource identifier of the server edit data conforms to the law, a preset message queue interface is called to update the edit data to a database in the data model, and an update instruction is triggered, including: when the uniform resource identifiers of the edited data conform to the method, calling a preset message queue interface to create a scheduling queue, and adding a preset storage task to the scheduling queue through a preset scheduling function to obtain a target scheduling queue; updating the editing data to a main distributed database in the data model through a target scheduling queue to obtain updated data; and storing the updating data to a copy distributed database in the main distributed database, and triggering an updating instruction.
When the uniform resource identifiers of the edited data conform to the method, an event monitor in the data model calls a preset message Queue interface Dispatch to create a Dispatch Queue, the edited data is conveniently, efficiently and multitaskally stored in the data model through the Dispatch Queue, the stored tasks are asynchronously added to the Dispatch Queue through a Dispatch function Dispatch _ async or a Dispatch function Dispatch _ async _ f to obtain a target Dispatch Queue, and the edited data is updated to a main distributed database in a distributed high-performance real-time database system Sophic DB in the data model through the target Dispatch Queue to obtain updated data; and updating the updating data to the copy distributed database in the SophiDB so as to realize the data consistency of the main distributed database and the copy distributed database. The data is edited and stored by adopting a distributed high-performance real-time database system SophiDB, so that the real-time property, the transaction real-time property and the high availability of the data are realized, and the resource waste, the server jam and the server crash caused by continuously polling data to update pages are avoided.
204. Receiving an updating instruction through a preset view model, and starting a preset page model according to the updating instruction;
specifically, the server receives an update instruction through a preset view model, and starts a preset page model according to the update instruction, including: receiving an updating instruction through a preset view model, and sending a request instruction to a data model according to the updating instruction, wherein the request instruction is used for indicating the data type of a set request, a uniform resource locator and an instruction of an asynchronous processing request; acquiring edit data corresponding to the request instruction from the data model to obtain target edit data; and sending the target editing data to a preset page model through a preset callback function so as to start the preset page model.
The request instruction can be in a GET () mode or a POST () mode, and the preset callback function can be an onreadystatechange function. The method comprises the steps of obtaining edit data which accord with the data type and the data format stored and displayed by a preset page model from the data model through a GET () mode or a POST () mode, sending the obtained edit data to the preset model through an online detatech function, and realizing page non-refreshing update of data through an ajax asynchronous loading technical means, thereby effectively realizing that the edit content of an edit page can be directly displayed on a preview page in real time without refreshing the page.
205. Rendering the editing data in the data model to a preset preview page through a preset page model;
specifically, the rendering, by the server, of the editing data in the data model to the preset preview page through the preset page model includes: creating a condition rendering instruction through a preset page model, and adding the condition rendering instruction to preset template elements to obtain condition template elements; rendering the editing data in the data model through the condition template elements to obtain rendering data, and uploading the rendering data to a block chain; and calling a preset virtual scrolling component to render the rendering data to a preset preview page.
The corresponding digest information is obtained based on the rendering data, and specifically, the digest information is obtained by hashing the rendering data, for example, using the sha256s algorithm. Uploading summary information to the blockchain can ensure the safety and the fair transparency of the user. The user device may download the summary information from the blockchain to verify whether the rendering data is tampered. The block chain referred by the application is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like.
