I'm trying to insert a binary attachment to CouchDB with nano. I have a JPG in data
returned by http.request
.
I save it with nano
as follows
db.attachment.insert( id, 'content', self._data, contentType, {rev: rev}, function(err, body) {
callback();
});
but when I try view it though a web browser the image is broken.
The file is full of UTF-8 escape characters which is visible when I pull it with CURL:
$ curl http://127.0.0.1:5984/web-crawler/doc-test.jpg/content
"ÿØÿà\u0000\u0010JFIF\u0000\u0001\u0001\u0001\u0000H\u0000H\u0000\u0000ÿâ\fXICC_PROFILE\u0000\u0001\u0001\u0000\u0000\fHLino\u0002\u0010\u0000\u0000mntrRGB XYZ \u0007Î\u0000\u0002\u0000\t\u0000\u0006\u00001\u0000\u0000acspMSFT\u0000\u0000\u0000\u0000IEC sRGB\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000öÖ\u0000\u0001\u0000\u0000\u0000\u0000Ó-HP \u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\
Content is not corrupted because if I save it to a file I can see the image.
var fs = require('fs');
fs.writeFile('logo.jpg', data, 'binary', function(err){
if (err) throw err
console.log('File saved.')
});
What is the right way to do it?
