Detailed Description
The present invention is described in further detail with reference to the following examples, but the scope of the present invention is not limited thereto.
The invention relates to a method for intercepting H5 document preview sharing at an iOS client, which is different from the method for opening a document by a common H5 link in an App in the prior art, and is based on the capability of the iOS, the document is coordinated and downloaded once and previewed for all or part of the document for multiple times, so that the problems of messy codes of partial models or overlarge occupied memory space when the document is opened by H5 are solved, and simultaneously, the document sharing, printing and storing can be carried out by utilizing the capability of the iOS file App (supported by more than iOS 11), and the capability of a user for operating the document at a mobile terminal is improved; the document may also be saved to a file App (supported above iOS 11), which may be implemented by a three-party App when editing of the document is required.
The method comprises the following steps:
step 1: clicking an H5 link by a user, and intercepting an APP;
step 2: the APP performs primary judgment on the content corresponding to the current link, if the content is a document, the next step is performed, and if the content is a document, the interception is removed, and the process is exited;
in the step 2, the documents include excel, word, ppt and pdf documents.
In the step 2, if the content corresponding to the current link is judged to be a non-document by the first-level judgment, the interception is removed, and the security protection is started.
In the invention, after a user clicks an H5 link, an App intercepts the link and judges whether the link is a document, specifically, judges whether the link contains documents such as excel, word, ppt, pdf and the like, if not, the original content is continuously executed, and if the links are document links of several types, the next judgment is needed to be continuously carried out.
And step 3: acquiring document information, performing multi-stage judgment, performing display rendering if the display condition is met, and performing the next step if the display condition is not met;
in the step 3, the document information is acquired and multi-level judgment including cache judgment and modification judgment is performed.
The cache judgment comprises the following steps:
step 3.1: acquiring a document fingerprint attached to downloading information of a current document;
step 3.2: comparing the document fingerprints with document fingerprints of files stored in an APP inner sandbox one by one;
step 3.3: and if the document with the same document fingerprint as the document fingerprint in the step 3.1 exists in the sandbox, the display condition is met, the corresponding document in the sandbox is directly displayed, and otherwise, modification judgment is executed.
The modification judgment comprises the following steps:
step 3.4: downloading a current document;
step 3.5: comparing the current document with a file stored in an APP internal sandbox;
step 3.6: if the similarity between the current document and any file reaches a threshold value, the display condition is met, the current document is blocked and extracted relative to the modified part of the file, and the file is synchronously blocked; otherwise, performing step 4;
step 3.7: deleting the unmodified part of the current document;
step 3.8: and displaying the file corresponding to the document in the sandbox which is rendered to modify the blocks of the part for corresponding replacement.
And in the sandbox, the modified blocks are attached to the file as replaceable document blocks and are independently stored.
And if the modified part is the picture, independently storing the picture.
In the invention, the step 3 is to compare the document with the files stored in the sandbox in the App one by one in principle, and if the files exist locally, the document display is rendered by directly using the local file and utilizing the UIDocument Interactive controller capability of the iOS.
In the invention, in practical application, the existing possibility is various, so the realization and the expansion of the method are carried out based on the basic thought;
in the aspect of implementation, namely cache judgment, namely judging whether the same document exists in the sandbox or not, wherein the comparison is realized through document fingerprints, in the application process, the document fingerprints are generally hash values of the document, and through comparing document fingerprints attached to the downloading information of the current document with document fingerprints of files in the APP sandbox, when the same document fingerprints, such as the hash values, exist, the two files are the same, the display condition is met, and the corresponding document in the sandbox can be directly displayed and rendered;
the extension comprises two situations, one is that the current document to be downloaded is a brand new document, and the other is that the current document to be downloaded is actually partially in a certain document in the sandbox, including deletion, addition, paragraph or content movement and the like, wherein the former is directly downloaded, and the latter needs to be further determined and processed; specifically, after the current document A is pre-downloaded, the document B in the sandbox with higher similarity to the current document A is marked by comparing with the file stored in the sandbox in the APP, C, D, E blocks are included in the current document A, the document B actually corresponds to C, D, F blocks, C, D blocks in the current document A are removed, E blocks are reserved, after processing, the document B is practically unchanged (still C, D, F blocks) and can be directly called and displayed, the reserved E blocks are attached to the F blocks, a new document can be formed by C, D blocks and E blocks, namely another representation of the document A, after processing, the storage space is obviously effectively reduced, and the document content is complete.
In the present invention, the threshold in step 3.6 generally means that the similar content of two documents exceeds 80% of the content of any document, and in practical application, one or more documents with the highest similarity to the current document are generally taken for processing, and even if a plurality of blocks in the current document are extracted, the total storage amount is much smaller than that of a completely stored document; when a plurality of documents with the highest similarity exist in the sandbox, the documents are all marked as the associated documents.
In the present invention, there is a case where the modified part is a picture, and generally, the picture is directly and independently stored, and the picture is directly replaced in order to avoid invalid replacement or excessive calculation amount.
And 4, step 4: and downloading the document corresponding to the link and executing post-processing.
In step 4, the post-processing includes storing the downloaded document in a sandbox in the APP and displaying the document.
If any opened document has messy codes, traversing the associated file in the sandbox; if the associated file exists, the garbled area is directly opened or replaced by the blocks corresponding to the garbled area in the associated file, otherwise, an error is reported.
In the invention, the document is downloaded by using a network request, is stored in a sandbox in the App, is prepared for local persistence for subsequent reopening, is displayed at the same time, and a user can also share, print and other operations on a software system of the iOS11 by using the iOS capability and can also edit the document by using the App supporting the editing capability.
In the invention, there is a possibility that the opened document has messy codes, which is divided into several processing logics:
(1) if the files are directly opened after cache judgment, traversing the associated files in the sandbox, and rolling back to the last normal opening or replacing the messy code areas by the blocks corresponding to the messy code areas in the associated files; the related files are the same files stored in the sandbox;
(2) if the code is opened after modification judgment, traversing the associated file in the sandbox, and replacing the messy code area by the block corresponding to the messy code area in the associated file; the related files are files with similarity exceeding a threshold value and stored in a sandbox;
(3) otherwise, an error is reported, and the document provider provides the document again.
In the invention, of course, the user can manually delete the document stored in the App.
