I want to convert an image in azure to base64. How can I achieve this using azure-storage package?
this.blobService.getBlobProperties(
'container',
path,
(err, properties, status)=> {
if (err) {
res.send(502, "Error fetching file: %s", err.message);
} else if (!status.isSuccessful) {
res.send(502, "The file %s does not exist", fileName)
} else {
res.header('Content-Type', properties['contentType']);
this.blobService.createReadStream('container', path,(error,response)=>{
}).pipe(res);
}
});
The response I get is like this, I want to convert this(octet/stream) to base64.
尝试
var dataUrl="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAA.."; var buffer = new Buffer(dataUrl.split(",")[1], 'base64');
There is no built-in Node.js method to do that. Some 3rd npm packages you can use, for example, https://www.npmjs.com/package/base64-stream
