}, {type:"Image",id:"2",

box:{x:58.5,y:135,width:70,height:50}},

{type:"Barcode",id:"cardNum",box:{x:2,y:1,width:30,height:10},

codeType:"CODE_128",moduleWidth: 2,resolution: 150}…]}。

step 2: storing the template files into a template library, wherein a plurality of template files are stored in the template library; the template file is provided with a unique template name, and the template file is identified by the template name, for example, the template name is "tpl 1" in this embodiment.

And step 3: the data uploading module receives document JSON data uploaded by a user and uploads the document JSON data to a server, the document JSON data are composed in a key-value form, the key is an id attribute of an object in a template file, and the value is a character string, an array or JSON.

A template file comprises a plurality of objects, the id attribute of each object corresponds to a key, and the id attributes of the objects can be the same.

In this embodiment, the content of the data uploaded by the user to generate the OFD file is:

{

pages : [ {template:"tpl1",

data:{

"depth": ABC department ",

"cardNum":"111111111",

"2":"data:image/jpg;base64,/9j/…/Z"…

}

} ],

docInfo:{

author: "author 1", title: "title x" },

customDatas:[ {name:"PQB_ID",value:"111"}, {

name:"AAA_ID",value:"22"} ],

attachments:[ {filename:"data.txt",

content, "attachment content …" } ",

}。

and 4, step 4: the object conversion module converts the object into the object in the XML format according to the OFD standard according to the object, the attribute and the data of the template file, and specifically comprises the following steps:

step 4-1: calling a template file in a template library through the template name, and obtaining all id attributes of objects in the template file according to keys to obtain an object to be converted; for example, in this embodiment, the content of the template file with the template name "tpl 1" is read from the template library to obtain a list of objects to be converted, the content under the data node of the data uploaded by the user is traversed, and the id in the template content is searched according to the key of each key value pair to obtain an object to be converted.

Step 4-2: the processing is performed according to the following conditions:

step S4-2-1: and if the value of the data of the object to be converted is the character string, directly assigning the character string to the value attribute of the object to be converted.

Step S4-2-2: if the value of the data of the object to be converted is the character string array, copying the object to be converted into a plurality of copies of the object to be converted with the same length as the array, and respectively assigning each value of the array to the value attribute of each copy of the object to be converted in sequence.

Step S4-2-3: and if the value of the data of the object to be converted is in the JSON format, respectively and correspondingly replacing each attribute value of the object to be converted by each attribute value in the JSON.

Step S4-2-4: converting the object to be converted or the copy of the object to be converted into the object in the XML format according to the OFD standard, wherein the conversion process specifically comprises the following steps:

step S4-2-4-1: the Page object is converted to the ofd: PageArea object of Doc _0\ Pages \ Page _ N \ content.

Step S4-2-4-2: convert Font, color attributes to ofd: Font, ofd: ColorSpace object for Doc _0\ public res.
