how can i write a string data using fs

[jo...@amt.in]

When I sending the following request ,

var request = require('request');

var fs = require("fs");    

var headers = {

'Authorization': 'Bearer cEet0ordwd4VsUHi9jnbQuWIY+fL5RKeSGP65HEbGtGznHQ4XOaOwaTDQqwLT0bI24oFKLtMvspYvPgi4qR3Bv1oMQp+Wak2x7TRSxsL/oqQN1kIzaWVcGTk9aK4ICxU6qK4tM0KHoAkjA1ahEJSswdB04t89/1O/w1cDnyilFU='

};

var options = {

url: 'https://api.line.me/v2/bot/message/6000684214622/content',

headers: headers

};

var r=request(options );

r.pipe(fs.createWriteStream('./m10.wav' ));

in here the type of the request is an object.

Now the file I can open with a music player. But when I writing the body of the request like,

request(options,function (err,res,body){

var p=body;

p.pipe(fs.createWriteStream('./m10.wav' ));

})

in here the type of body is string.

I can't open the file. It shows error. How can I write this file and When I checking the type of both responce first one is an object type and second once is a string type. Any problem for writing string data using fs?

Few things, one really important:

You shared your API token with the world!

If you can, delete that token and in the future, replace it with a placeholder when you're posting examples.

Second, request you can handle errors in streams, e.g.

    request(options).pipe(fs.createWriteStream(filename)).on('error', err => console.log(err));

However, this is only a part of the solution - the problem is that request doesn't think that e.g. 404 response will be an error - it'll let you handle it. Check this answer: http://stackoverflow.com/a/14972828/162070

What it says is to check for the status code before creating your write stream, something like this:

    const r = request(url)

    r.on('response', function (resp) {

      if (resp.statusCode > 399) { // e.g. 400, 404 or whatever else you consider failure

        throw new Error();

      }   

      r.pipe(new WritableStream())

    });
