In my blog Test BTP SAP Print Service With Postman, I have explained how to SAP Print Service with postman. In this blog, I will explain how to use it to print document in an UI5 application deployed in BTP cloud foundry run time. To use a PDF document, I will combine the code with my blog Render and View PDF in SAP UI5 with Forms service by adobe in BTP.
Prerequisite:
1, You have installed CF Client .
2, You have installed Nodejs .
3, You have installed Cloud MTA Build Tool .
4, You have finished Initial Setup for Document Management Service, Integration Option.
5, You have finished Onboarding Repository.
6, Destination for CMIS service key has been created as step 1 in blog .
7, You have installed VSCode (optional).
Steps :
Step 1: Generate SAPUI5 project with easy-ui5 .
Use the following commands to open the project with visual code .
Step 2: Change the view MainView.view as the following code:
<View controllerName="com.sap.printui5.controller.MainView" xmlns:mvc="sap.ui.core.mvc" xmlns:core="sap.ui.core" displayBlock="true" xmlns="sap.m">
<Page id="page" title="{i18n>title}" showNavButton="true">
<content>
<VBox width="100%" direction="Column" id="vbox0" alignContent="Center">
<items>
<HBox width="100%" id="hbox1">
<items>
<Label id="filenamel" width="200px" class="sapUiSmallMargin" text="FileName:" />
<Input id="filename" width="200px" editable="true" />
</items>
</HBox>
<HBox id="hbox4">
<Select id="select1" showSecondaryValues="true" width="200px" class="sapUiSmallMargin" items="{ path: '/templates' }">
<core:ListItem id="listitem1" text="{name}" />
</Select>
<Button text="PDF Render" id="button2" class="sapUiSmallMargin" type="Emphasized" width="200px" press="pdfRender" />
</HBox>
</items>
<HBox width="100%" id="hbox5">
<Select id="select" showSecondaryValues="false" class="sapUiSmallMargin" width="200px" items="{ path: '/printQs' }">
<core:ListItem id="listitem" text="{qname}" additionalText="{qdescription}" />
</Select>
<Button text="Send To PrintQ" id="button3" class="sapUiSmallMargin" type="Emphasized" width="200px" press="pdfPrint" />
</HBox>
<ScrollContainer id="scrollc1" height="100%" width="100%" horizontal="true" vertical="true">
<FlexBox id="flexb1" direction="Column" renderType="Div" class="sapUiSmallMargin">
<PDFViewer id="pdfview" source="{/Source}" title="{/Title}" height="{/Height}">
<layoutData>
<FlexItemData id="flexitemdata1" growFactor="1" />
</layoutData>
</PDFViewer>
</FlexBox>
</ScrollContainer>
</VBox>
</content>
</Page>
</View>
Step 3: Create folder service under webapp, create file named FileUpload.js under folder service . Change the file FileUpload.js as the following code:
// @ts-ignore
sap.ui.define("FileUpload", [
"sap/ui/base/Object"
], function (ui5Object) {
"use strict";
return ui5Object.extend("ui5applicationmodule.service.FileUpload", {
printDm: function (content, filename) {
return new Promise((resolve, reject) => {
// @ts-ignore
var data = new FormData();
data.append("media", content, filename)
let request = new Request("/print/dm/api/v1/rest/print-documents", { method: "POST", body: data });
request.headers.append("scan", "true");
request.headers.append("If-None-Match", "*");
request.headers.append("DataServiceVersion", "2.0");
request.headers.append("Accept", "*/*")
fetch(request).then(res => res.text()).then(data => resolve(data)
).catch(err => reject(err));
});
},
printTask: function (dmId, qname, filename) {
return new Promise((resolve, reject) => {
var url = "/print/qm/api/v1/rest/print-tasks/".concat(dmId);
var bodyJson = {
"numberOfCopies": 1,
"username": "test user",
"qname": qname,
"metadata": {
"business_metadata": {
"business_user": "user1",
"object_node_type": "object_node_1"
},
"version": 1.2
},
"printContents": [
{
"objectKey": dmId,
"documentName": filename
}
]
}
var body = JSON.stringify(bodyJson);
var myHeaders = new Headers();
myHeaders.append("If-None-Match", "*");
myHeaders.append("Content-Type", "application/json");
var requestOptions = {
method: 'PUT',
headers: myHeaders,
body: body,
redirect: 'follow'
};
fetch(url, requestOptions).then(res => res.status).then(data => resolve(data)).catch(err => reject(err));
})
},
getPrintq() {
return new Promise((resolve, reject) => {
// @ts-ignore
const request = new Request("/print/qm/api/v1/rest/queues");
request.headers.append("Content-Type", "application/json");
// @ts-ignore
fetch(request).then(res => res.json()).then(data => {
resolve(data)
}).catch(err => {
reject(err);
})
})
},
render: function (template, content) {
return new Promise((resolve, reject) => {
// @ts-ignore
var rendercont = btoa(content);
var pdfcontent = {
embedFont: 0,
formLocale: "en_US",
formType: "print",
taggedPdf: 1,
xdpTemplate: template,
xmlData: rendercont
};
var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");
var requestOptions = {
method: 'POST',
headers: myHeaders,
body: JSON.stringify(pdfcontent),
redirect: 'follow'
};
fetch("/adobeapi/v1/adsRender/pdf?templateSource=storageName&TraceLevel=0", requestOptions).then(res => res.json()).then(data => {
const deccont = atob(data.fileContent);
const byteNumbers = new Array(deccont.length);
for (let i = 0; i < deccont.length; i++) {
byteNumbers[i] = deccont.charCodeAt(i);
}
const byteArray = new Uint8Array(byteNumbers);
const blob = new Blob([byteArray], { type: "application/pdf" });
const docurl = URL.createObjectURL(blob);
resolve(docurl);
}).catch(err => reject(err));
});
},
getTemplates: function () {
return new Promise((resolve, reject) => {
var request = new Request("/adobeapi/v1/forms");
var templates = [];
var temp = "";
fetch(request).then(res => res.json()).then(data => {
data.forEach(form => {
temp = form.formName
form.templates.forEach(template => {
temp = temp.concat("/").concat(template.templateName);
templates.push({ "name": temp });
temp = "";
});
});
resolve(templates)
}).catch(err => reject(err));
});
}
});
})Step 4: Change the controller MainView.controller.js as the following code:
sap.ui.define(
["./BaseController",
"sap/m/MessageBox",
"sap/base/security/URLWhitelist",
"../service/FileUpload",
"sap/ui/model/json/JSONModel"],
/**
* @param {typeof sap.ui.core.mvc.Controller} Controller
*/
function (Controller, MessageBox, URLWhitelist, FileUpload,JSONModel) {
"use strict";
return Controller.extend("com.sap.printui5.controller.MainView", {
onInit: function () {
if (!this._fileUpload) {
this._fileUpload = new FileUpload();
}
this._fileUpload.getPrintq().then(data => {
this.byId("select").setModel(new JSONModel({"printQs":data}) ); }).catch(err => { MessageBox.information(JSON.stringify(err)) });
this._fileUpload.getTemplates().then(data=>{
var model = new JSONModel({"templates": data});
this.byId("select1").setModel(model);
}).catch(err=>{
console.log("template is empty")
MessageBox.information(JSON.stringify(err))});
},
pdfPrint: function(){
if (!this._fileUpload) {
this._fileUpload = new FileUpload();
}
var printQ = this.byId("select").getSelectedItem().getText();
var filename = this.byId("filename").getValue();
var objurl = this.byId("pdfview").getSource();
if(objurl&&filename){
fetch(objurl).then(r=>r.blob()).then(blob=>{
this._fileUpload.printDm(blob,filename).then(dmid=>{
console.log(dmid);
this._fileUpload.printTask(dmid,printQ,filename).then(data=>{
console.log(data);
if(data === 204){
MessageBox.information("document has been sent to ".concat(printQ))
}
})
}).catch(err=>console.log(err))
})}else{
MessageBox.information("Please input filename or render pdf first");
}
},
pdfRender: function () {
var printd = "<?xml version="1.0" encoding="UTF-8"?><form1><LabelForm><DeliveryId>Mirum est ut animus agitatione motuque corporis excitetut.</DeliveryId><Position>Ego ille</Position><MaterialNo>Si manu vacuas</MaterialNo><Quantity>Apros tres et quidem</Quantity><Package>Mirum est</Package><QRCode>01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789</QRCode></LabelForm><LabelForm><DeliveryId>Ad retia sedebam: erat in proximo non venabulum aut lancea, sed stilus et pugilares:</DeliveryId><Position>Licebit auctore</Position><MaterialNo>Proinde</MaterialNo><Quantity>Am undique</Quantity><Package>Ad retia sedebam</Package><QRCode>01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789</QRCode></LabelForm><LabelForm><DeliveryId>meditabar aliquid enotabamque, ut, si manus vacuas, plenas tamen ceras reportarem.</DeliveryId><Position>Vale</Position><MaterialNo>Ego ille</MaterialNo><Quantity>Si manu vacuas</Quantity><Package>Apros tres et quidem</Package><QRCode>01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789</QRCode></LabelForm></form1>";
var filename = this.getView().byId("filename").getValue();
if (!this._fileUpload) {
this._fileUpload = new FileUpload();
};
var template = this.byId("select1").getSelectedItem().getText();
this._fileUpload.render(template,printd).then(url => {
var pdfSource= new JSONModel({
"Source": url,
"Title": "Outbound Delivery",
"Height": "600px"
});
URLWhitelist.add("blob");
this.byId("pdfview").setModel(pdfSource);
}).catch(err => {
console.log("render failed");
console.log(err);
})
}
});
}
);
Step 5: Add router in xs-app.json under folder approuter .
{
"welcomeFile": "uimodule/index.html",
"authenticationMethod": "none",
"logout": {
"logoutEndpoint": "/do/logout"
},
"routes": [
{
"source": "^/adobeapi/(.*)$",
"target": "/$1",
"authenticationType": "xsuaa",
"csrfProtection": false,
"destination": "adobeapi"
},
{
"source": "^/print/(.*)$",
"target": "/$1",
"authenticationType": "xsuaa",
"csrfProtection": false,
"destination": "printServiceApi"
},
{
"source": "^/uimodule/(.*)$",
"target": "$1",
"authenticationType": "none",
"localDir": "uimodule/webapp"
}
]
}
Step 6: Create destination ‘adobeapi’ for form service by adobe and ‘printServiceApi’ for SAP Print Service with plan sender.
Name: adobeapi
Type: HTTP
URL: uri from previous screen
Client ID: uaa>clientid. from previous screen
Client Secret: uaa>clientsecret. from previous screen
Token Service URL: uaa>url + /oauth/token from previous screen
Token Service User: uaa>clientid. from previous screen
Token Service Password: uaa>clientid. from previous screen
Name: printServiceApi
Type: HTTP
URL: service_url from previous screen
Client ID: uaa>clientid. from previous screen
Client Secret: uaa>clientsecret. from previous screen
Token Service URL: uaa>url + /oauth/token from previous screen
Token Service User: uaa>clientid. from previous screen
Token Service Password: uaa>clientid. from previous screen
Step 7: Use the following command to build deploy the application to BTP cloud foundry run time.
mbt build
cf login
cf deploy mta_archives/printui5_0.0.1.mtar
Step 8: Test the deployed application:
Step 9: Check print task in print Queue:
