I study binary data. I can not figure out the following:

I get the image from the network:

var request = require('request'); var fs = require('fs'); var options = { url: 'url', // encoding: 'binary' // понимаю, что можно использовать, но хотелось бы самому.. } request(options, function (error, response, body) { if (!error && response.statusCode == 200) { var data = new Buffer(body); fs.writeFile('image.png', data, 'binary'); console.log(data); } })

conclusion:

  PNG IHDR  2 4IDAT 5 =O QF   .  " % :  HLLH |`  U  4 ~ ~ G     /x        qw  L& v{|     Kr   h6    E   R"x      > j q  Q   r I,  |=9b #    , N13$yY  .  ^kL        9&   <  V     }dsg    1 gQ ?  V6  W   vcI ;  pwJoj  ;     hb    E   )%r   $r < T G NIEND B`

After writing this data to a local file, the image does not want to be displayed.

Interested in: What is the type of data that I get? Is this not binary data? How to do right?

    Try request (options) .pipe (fs.createWriteStream ('image.png')); Everything works fine for me
