In the prior art, a service management system, that is, a data management system applied to various services generally has a document export function, and in order to meet user requirements such as a requirement that data can be exported when being visible, an export interface is usually designed to implement the export function.
At present, two common implementation modes are provided, one mode is that a temporary document is generated by a background, namely a server, then a URL address is returned to a foreground, namely a user, and the user acquires a new page through a browser to download the document. And the other method is that data is obtained asynchronously, the data is spliced into a document in an html format, then the suffix format of the document is modified, and then the document is exported.
Document downloading is carried out on the basis of a new page of the browser, so that the identity information of a user is reserved in a cache cookie of the browser or carried in a URL (uniform resource locator), and the situations of cross-domain limitation and unsafe identity information exist. Meanwhile, the temporary document generated by the server occupies a storage space and needs to be cleaned regularly. Moreover, before exporting a document, a user needs to perform operations such as query screening preview of data, and in the related art, a query interface and an export interface are usually maintained separately, which increases the maintenance cost and lowers the development efficiency. Furthermore, the embodiment of the invention provides a document export method to solve the problems in the prior art.

The following describes steps in the methods provided by the embodiments of the present invention and technical effects achieved by the methods in combination with the data management system.
Referring to fig. 3, fig. 3 is a flowchart illustrating a document exporting method according to an embodiment of the present invention.
It should be noted that the method provided by the embodiment of the present invention may be used to derive multiple types of documents such as pdf, word, excel, csv, and the like. For convenience of understanding, the embodiment of the present invention will be described by taking an example of exporting an excel document, adopting axios technology by a foreground, i.e., a user side, and adopting asp.
Step S202, when receiving a user request, a user side judges whether the user request is a exporting request;
it can be appreciated that the data management system is used to manage data in a business process, which can interact with a user through a business interface at a user end. When a user performs an interactive operation on a service interface of a user side, the user side can receive a user request corresponding to the interactive operation.
The export request may refer to a user request for obtaining data from the data management system and saving the data in a document form to the local storage space of the user terminal.
Optionally, when the user end receives the user request, an interceptor in axios technology, i.e., an interceptor, may be used to intercept the user request, and then determine whether the user request is an export request according to a request header of the user request. If yes, go to step S204.
Step S204, the user terminal adds a mark in the request header of the user request;
it will be appreciated that a user may export multiple types of documents, and that a flag may be employed to indicate the document type of the document to be exported, i.e., the target document. When the user side and the server side perform data interaction, the server side can determine the document type of the target document to be generated based on the mark.
Optionally, when the user request is an export request, the user side adds a mark in a request header of the user request, that is, adds a mark in the headers.
It can be understood that, after adding the mark in the request header of the user request, the user terminal may further set the response type, i.e. the data type used by the server terminal to return the target document. For example, the client may set the ResponseType to be a blob data type, so that the server returns the target document to the client according to the blob data type.
Step S206, the user side sends the attribute name array obtained according to the mark to the server side;
it can be understood that, the service interface of the user side has a service name corresponding to each data, and the service name refers to a service meaning represented by the data. The service name and the attribute name have a first mapping relation, namely each service name has a corresponding attribute name, the server side can acquire corresponding data according to the attribute names, and the attribute name number group comprises a plurality of attribute names.
Optionally, the user side may traverse the service names of each column of data in the service interface triggering the user request according to the document type represented by the mark to obtain a plurality of service names; obtaining an attribute name corresponding to each service name according to the first mapping relation, obtaining a plurality of attribute names, and generating an attribute name array; and sending the attribute name array to a server.
If the derived document is an excel document, the business name of each column of data in the business interface can be, for example, "company name", "user number", "user name", and the like.
Optionally, the ue may further set an attribute parameter, such as options, in the ue request, where the attribute parameter is used to agree on a mapping relationship between a service name on the ue and an attribute name on the service side, and set an order of the attribute names.
Step S208, the server side acquires a data set according to the attribute name array;
it can be understood that the server stores data in the business process, and each data has a corresponding attribute name, that is, the data and the attribute name have a second mapping relationship.
Optionally, after receiving the attribute name array, the server may obtain corresponding data according to each attribute name and the second mapping relationship, so as to obtain a data set. The data corresponding to each attribute name can be understood as the data corresponding to each column of service names in the service interface of the user side.
Step S210, the server sends a target document generated according to the attribute name array and the data set to the user side;
optionally, after the server acquires the data set, the server may determine the document type of the target document according to the mark, arrange the attribute name number group and the data set based on the attribute parameters, arrange the attribute name number group according to a set order, and fill the data set into the corresponding attribute name to obtain the target document; and then sending the target document to the user side according to the appointed data type.
Step S212, the user end creates a export link according to the target document so as to enable the user to export the target document;
optionally, after receiving the target document sent by the server, the user may first determine the data type, and if it is determined that the target document is the blob data type, if so, create an export link based on the target document, that is, create a URL resource and a tag object a, and assign the URL to an href attribute of the tag object a, where the href attribute is an attribute of the URL of the tag object a used to specify a hyperlink target.
The tag object can be set to be hidden, that is, when the user triggers to export the document, the browser at the user end does not redisplay an interface for downloading the document, and can display the downloading progress and obtain the target document in the current business interface.
Based on the design, the document export method of the embodiment of the invention is applied to a data management system comprising a user side and a server side, and judges whether a user request is an export request or not when the user request is received by the user side; then the server side acquires a data set according to the attribute name number group and sends a target document generated according to the attribute name number group and the data set to the client side; and finally, the user terminal creates an export link according to the target document so as to enable the user to export the target document. Compared with the prior art, the method judges the user request and adds the mark for representing the document type, so that the export function and other business functions can share one interface, thereby reducing the maintenance cost; the server can generate the document corresponding to the document type based on the mark without generating a temporary file, thereby reducing the occupation of the memory.
Optionally, regarding step S202, the determination of the user request determines whether to execute a subsequent step of exporting the document, and further the embodiment of the present invention provides a possible implementation manner.
It can be understood that, when a user needs to export a document in a service interface, operations such as query, screening, preview and the like are performed on data, that is, content to be exported needs to be displayed to the user first, the service functions are that the user side acquires data from a server side for display, the export function is that the user side acquires data from the server side for local storage, and the service functions and the export function have coincident service steps.
Therefore, when the user terminal receives the user request, the user terminal can judge based on the parameter value in the user request, distinguish the export request from the requests triggered by the service functions, and simultaneously enable the export function and the service functions such as the query function to share one interface. Therefore, the development efficiency is improved, and the maintenance cost of the interface is reduced.
Optionally, when the user performs an interactive operation on the service interface, if the interactive operation is a export operation, assigning a preset export parameter, such as export, in the user request to a first preset value.
Then intercepting when the user side receives the user request, and judging whether the user request is a exporting request by judging whether the preset exporting parameter is a first preset value; if not, the user request is a non-output request; if the exponent parameter is the first preset value, the user request is a derivation request. And when the user request is judged to be the export request, deleting the preset export parameters so as to avoid that the request triggered by other service functions is judged to be the export request by mistake.
Optionally, regarding step S206, the embodiment of the present invention provides a possible implementation manner. Referring to fig. 4, step S206 may further include the following steps:
step S206-1, carrying out format conversion on the attribute name array obtained according to the mark to obtain a target attribute name array;
optionally, after the user acquires the attribute name array, format conversion needs to be performed on the attribute name array, that is, the attribute name array is converted into a format that can be analyzed by the server. For example, the obtained attribute name array is a json object, and the json object can be converted into a json character string through a stringiness function, so that a target attribute name array is obtained.
Step S206-3, encoding the target attribute name array;
alternatively, the encoderURIComponent function may encode the data in string format as a URI component.
The user side can adopt an encoderURIComponent function to encode the target attribute name array with the format of json character strings.
Step S206-5, adding the encoded target attribute name array to a request header of a user request to obtain a target request;
it can be understood that, in step S206, attribute parameters options are introduced, and the attribute parameters can be understood as mapping relationships between service names and attribute names agreed by the user side and the service side, and the order of the attribute names is set.
Its attribute parameters options can be expressed as { "Label": "chinese title 1", "Property": "viewmodel attribute 1" }, { "Label": "Chinese title 2", Property ": "viewmodel attribute 2" }, … ], where a chinese title represents a service name, a viewmodel attribute represents an attribute name, and the arrangement order of the attribute names is set, that is, the 1 st column is a chinese title 1, the corresponding viewmodel attribute 1 is the 1 st column, the 2 nd column is a chinese title 2, and the corresponding viewmodel attribute 2 is the 2 nd column, etc.
If the derived attribute name is an excel document, the encoded target attribute name array is a key which can be used as the attribute parameter excel-options, and is added into a request header of a user request to obtain a target request.
For convenience of understanding, in the embodiment of the present invention, an order service is taken as an example, and the attribute parameter excel-options may be expressed as:
[ { "Label": "company name", "Property": "company name" }, { Label ": "user number", "Property": "Createusercode" }, { "Label": "user name", "Property": createusername "}, {" Label ": "IP address", "Property": RemoteIP "} ].
Step S206-7, sending the target request to a server;
optionally, the user sends the target request added with the target attribute name array and the tag to the server.
Optionally, with respect to the step S208, the embodiment of the present invention provides a possible implementation manner. Referring to fig. 5, step S208 may further include the following steps:
step S208-1, decoding the target request to obtain a target attribute name array;
optionally, after receiving the target request sent by the user, the server may determine whether there is a mark in the request header of the target request through a filter, such as an onactionexecution function in the ActionFilterAttribute. For example, when it is judged that the target request has a flag application/excel-stream in the request header, it is determined that the target request is a derivation request.
It can be understood that the export request and the query request share one interface, and the query request may perform paging display on data in the service interface of the user side, that is, the query request executed by the server side is to obtain data by paging query, where each page has a set number of rows. The server executes the export request and needs to acquire the data to be exported from all the data.
Optionally, after the server determines that the target request is a export request, the server may modify the row number parameter of each page, such as a rows parameter, and modify the row number parameter to a maximum value, such as a maximum value of int32, so that the data to be exported may be quickly acquired.
Optionally, after the server determines that the target request is a export request, it determines whether a key of excel-options, that is, a target attribute name array, exists in a request header of the target request, and if so, reads the target attribute name array, and analyzes the UrlDecode by calling HttpUtility, that is, decodes the target request, so as to obtain the target attribute name array.
S208-3, performing deserialization on the target attribute name array to obtain an attribute name set;
optionally, after obtaining the target attribute name array, the server performs deserialization Deserialize on the target attribute name array, that is, the target attribute name array in the format of json character string is converted into an object format by using a json Deserialize function, so as to obtain an attribute name set.
Step S208-5, acquiring a data set according to the attribute name set;
optionally, the attribute name set includes a plurality of attribute names, and the server may obtain data corresponding to each attribute name according to the attribute name set and the second mapping relationship, so as to obtain a data set.
It can be understood that, based on the business requirements, until the user performs the export operation on the set business interface, the data set needs to be screened, that is, it needs to be determined whether the data is a paging result set, where the paging result set represents the data displayed on the set business interface.
Optionally, the output Object may be obtained from the outputformaterwritecontext, and it is determined whether the Object is a paging result set, that is, it is determined whether the data inherits an interface of the paging result set according to the return value, if the data inherits the interface, the data is data that needs to be exported, and if the data does not inherit the interface, the data does not need to be exported.
Optionally, for the step S210, the embodiment of the present invention provides a possible implementation manner. Referring to fig. 6, step S210 may further include the following steps:
step S210-1, generating a document object;
alternatively, if an excel document is exported, the server can create a workbook object and create a worksheet by calling the CreateSheet interface of the workbook object to generate a document object.
Step S210-3, adding each attribute name in the attribute name set to the document object according to a preset sequence;
for example, the server may create a header for the worksheet based on the set of attribute names; or performing inverse mapping by using the first group of data of the data set to obtain the attribute name corresponding to each data in the data group, so as to obtain the header.
A temporary variable such as a Dictionary < string, int > type may be used to record a subscript position corresponding to each attribute name in the header, the subscript position indicating the order of the respective attribute names, i.e., the order of the respective attribute names is arranged based on the temporary variable.
Step S210-5, traversing the data set, adding each data in the data set to a document object, and generating a target document;
optionally, the server may cycle through the data set, obtain a subscript position of an attribute name corresponding to each data by reflection mapping, fill each data into a new row of the working table according to the subscript position in the temporary variable, and obtain a target document, where the document type of the target document is the document type corresponding to the label.
Alternatively, the server may create an object such as a MemoryStream to be returned to the client, call the Write interface of the workbook object, and Write the worksheet into the MemoryStream to obtain the return result value.
Step S210-7, sending the target document to a user side;
optionally, the server sends the target document to the user side, that is, the server may call an interface corresponding to the outputformaterwritecontext, and write the return result value into a response stream for responding to the user side, so that the user side obtains the target document.
Through the steps, the mark is added in the user request and used for informing the server side of generating the document corresponding to the document type, a temporary document does not need to be generated, the memory is effectively prevented from being occupied, and the invalid document does not need to be cleaned regularly. And moreover, the parameters in the user request are judged, so that the interfaces of the export function and the query function can be combined into a whole, and the maintenance cost is reduced. By adding the self-defined parameters in the request header of the user request, the method is not influenced by cross-domain, and the identity information cannot be stored in the cache cookie of the browser, so that the information safety is ensured. Meanwhile, the document is generated by the server side and returned to the user side, data splicing and document format changing are not needed at the user side, the compatibility problem of the document can be effectively avoided, error prompt of the user side is avoided, and therefore user experience is improved.
It can be understood that the export request needs to transmit the acquired data to the client through the server, so that the user exports the data through the client, the processing time is long, and the interrupt processing is avoided when the client misjudges and processes the export request overtime.
The preset time parameter, such as timeout, may be set to a second preset value, such as 0, when the ue determines that the user request is a derivation request. Meanwhile, the method can prevent long-time non-response under the condition that more user requests exist, and avoid that the user triggers the export request for many times so as to improve the user experience.
