jsreportonline - How to save in pdf file

I've finally got the jsreportonline at least generating the file. Here's my code:

request.post({
  url: 'https://xxxx.jsreportonline.net/api/report',
  json: true,
  headers: {
    "Content-Type": "application/json",
    "Authorization" : "Basic "+new Buffer(username:pwd).toString('base64')
  },
  body: {
    "template" : {'shortid" : xxxxx},
    "data" : xxxx,
  }
}, function(err, res, body) {
  **** HERE IS THE PROBLEM ****
});

I have no clue how to write the pdf output stored within variable 'body' to a file. I've tried:

var pbs = fs.createWriteStream('./report.pdf');
pbs.write(body);
pbs.end();

I've tried:

var pbs = fs.createWriteStream('./report.pdf', {defaultEncoding: 'binary'});

... but the PDF file never is displayed properly. I know the code works because I can set an option on the call:

"options" : {
  "reports" : {"save" : true}
}

... and the report is saved to my jsreportonline account and renders fine.

Thanks for any help.

You shouldn't use the callback but rather directly pipe the stream returned from the request.post. See this in docs here. Example:

var request = require('request')
var fs = require('fs')

request.post({
  url: 'https://xxx.jsreportonline.net/api/report',
  json: true,
  headers: {
    'Content-Type': 'application/json',
    'Authorization' : 'Basic '+new Buffer('xxx:yyy').toString('base64')
  },
  body: {
    'template' : {'shortid" : xxxxx},
    'data' : xxxx,
 }
}).on('error', function (err) {
  console.log(err)
}).pipe(fs.createWriteStream('report.pdf'))

You can use 'busboy' to write the uploaded file to a file in server directory.

Saving the file:-

var

express = require("express"), os = require('os'), path = require('path'), Busboy = require('busboy'), fs = require('fs'), app = express();

app.post('/savepdf', function(req, res) {

    var busboy = new Busboy({
        headers : req.headers
    });

    busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
        console.log("OS tmp dir ========>" + os.tmpDir());
        console.log("Base name ========>" + path.basename(filename));
        var saveTo = path.join(os.tmpDir(), path.basename(filename));
        file.pipe(fs.createWriteStream(saveTo));
    });
    busboy.on('finish', function() {
        res.writeHead(200, {
            'Connection' : 'close'
        });
        console.log("Upload finished !!!");
        res.end("Success!");
    });
    return req.pipe(busboy);

});

app.listen(3000);
console.log('app started ');

HTML Page used to test the file:-

<html>
    <head>
        <title>Post Tool</title>
    </head>
    <body>
        <h1>Save PDF </h1>
        <h2>Upload Document</h2>
        <form action="/savepdf" method="post" enctype="multipart/form-data">
        <input type="text" name="uploadtext" id="uploadtext" value="Good" />
    Choose a file : <input type="file" name="uploadfile" id="uploadfile" multiple/>

    <input type="submit" value="Upload" />
</form>
    </body>
</html>

Output:-

The file has been saved successfully in temp folder (i.e. windows path below).

C:\Users\userid\AppData\Local\Temp

The file name would be same as the uploaded file name.
