如何将字符串传递给 fs.readFileSync

Question

I'm trying to convert string in to Buffer using readFileSync .It's return buffer with hard coded string.but not when i pas string.

----working ---

const buffer = fs.readFileSync('./test/JFwZCrdEojAr09ajT8EPZmo.jpg',{ encoding: 'utf8' });

----not working ---

var pathString = './test/JFwZCrdEojAr09ajT8EPZmo.jpg';
const buffer = fs.readFileSync(pathString,{ encoding: 'utf8' });

i'm getting bellow error

Error: ENOENT: no such file or directory, open './test/JFwZCrdEojAr09ajT8EPZmo.jpg'

Both ways working fine in local machine.but when deploy in to server,above happening.

Answer 1

Both should be work. check your image file still exists.

Answer 2

This is not answer and will be deleted or transformed to the answer depending on the results.

@Yasiry, could you please run this code on you machine and post the output?

const fs = require('fs');

try {
    fs.readFileSync('./test/JFwZCrdEojAr09ajT8EPZmo.jpg', { encoding: 'utf8' });
    console.log('file using STRING found');
} catch (e) { console.log('file using STRING NOT found'); }

try {
    const pathString = './test/JFwZCrdEojAr09ajT8EPZmo.jpg';
    fs.readFileSync(pathString, { encoding: 'utf8' });
    console.log('file using VARIABLE found');
} catch (e) { console.log('file using VARIABLE NOT found'); }

I assume, both will fail or success. In this case you need to check other parts of your code.
