Use SAP Cloud SDK to render PDF document with BTP SAP Forms Service by Adobe rest API

In my blogs Configure the SAP BTP Cloud Foundry Environment Subaccount with SAP Forms Service by Adobe and Test with Postman, I have explained configuring ads and testing ads rest api with postman . I have received many queries about this blog . One question is how to use SAP cloud sdk to call ads rest api to render pdf document .

I assume you have installed nodejs ,yeoman. If you have not installed yeoman, you can use the following command to install it .

npm install -g yo

Also suggest you instll generator-saphanaacademy-mta with the folowing command :

npm install -g generator-saphanaacademy-mta

You have install cloud foundry cli and mta tool . For cloud foundry cli, you can refer the toturial .

For MTA tool, you can install it with :

npm install -g mbt

Base on all these prerequisites, today I want to blog the steps on how to use SAP Cloud SDK to render PDF document with BTP SAP Forms Service by Adobe rest API .

The following is the steps :

Step 1 : Check SAP Cloud SDK for Forms Service by Adobe API in API hub and download API specification .

Step 2 : generate a mta project with yeoman .

Step 3: use visual code to change the code :

Step 4: add a folder external under srv and move the downloaed ADS specification file into folder external

Step 5: Generate a typed client by running the generator

create folder CF_ADSRestAPI under folder external .

rename API specification file to CF_ADSRestAPI.json

add the following line in srv/package.json

,”@sap-cloud-sdk/openapi”: “latest”

run the following command:

cd srv

npm install

openapi-generator -t –input externalCF_ADSRestAPI.json –outputDir externalCF_ADSRestAPI

Step 6: add the following code to server.js

const {ADSRenderRequestApi} = require('./external/CF_ADSRestAPI/CF_ADSRestAPI/ads-render-request-api')
const { StoreFormsApi } =require('./external/CF_ADSRestAPI/CF_ADSRestAPI/store-forms-api')


app.get('/srv/ads/adsforms', function (req, res) {
    if (req.authInfo.checkScope('$XSAPPNAME.User')) {
        // res.setHeader()  
      StoreFormsApi.formGet('labelprint').execute({ destinationName:'ads-rest-api' }).then(data=>{res.status(200).json(data)}).catch(err=>{res.status(200).json(err)});         
    } else {
        res.status(403).send('Forbidden');
    }
});
app.get('/srv/ads/render',function(req,res){
    if (req.authInfo.checkScope('$XSAPPNAME.User')){

    const data = "<form1><LabelForm><DeliveryId>8000311</DeliveryId> <Position>0010</Position> <MaterialNo>M100001</MaterialNo><Quantity>123456.321</Quantity> <Package>P111111</Package><QRCode>01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789</QRCode></LabelForm></form1>"

    const bodyE = new Buffer(data).toString('base64')
    
    renderinput = {
        "embedFont": 0,
        "formLocale": "en_US",
        "formType": "print",
        "taggedPdf": 1,
        "xdpTemplate": "labelprint/PrintLabel",
        "xmlData": bodyE
          }
        const queryP =  { templateSource: 'storageName', TraceLevel: 1 }
        ADSRenderRequestApi.renderingPdfPost(renderinput,queryP).execute({destinationName:'ads-rest-api' }).then(pdf=>{res.status(200).json(pdf.fileContent)}).catch(err=>{res.status(500).send(err)})



    }else{
        res.status(403).send('Forbidden');

    }

})
