Nodejs uploading base64 image to azure blob storage results to “ResourceNotFound” error

问题

Here is the post request JSON :

{
    "name":"images.jpg",
    "file":"data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEAAkGBxQTEhIUEhIUFBUV…K9rk8hCAEkjFMUYiEAI+nHIpsQh0AkisDYRTOiCAbWVtgCtI6IlkHh7LDTQXLH0EIQBj//2Q=="
}

And here's my node controller under the request /upload route, I am using createBlockBlobFromText() from azure-storage.

var azure = require('azure-storage');
var blobSvc = azure.createBlobService('myblob.blob.core.windows.net/mycontainer', THE_KEY);

controllers.upload = function (req, res, next){

    var startDate = new Date();
    var expiryDate = new Date(startDate);

    var sharedAccessPolicy = {
        AccessPolicy: {
            Permissions: azure.BlobUtilities.SharedAccessPermissions.WRITE,
            Start: startDate,
            Expiry: expiryDate
        }
    };

    var sharedAccessSignatureToken = blobSvc.generateSharedAccessSignature('resources', req.body.file, sharedAccessPolicy);
    var sharedBlobService = azure.createBlobServiceWithSas(blobSvc.host.primaryHost + '/' + 'mycontainer' + '?' + sharedAccessSignatureToken);

    sharedBlobService.createBlockBlobFromText('mycontainer', req.body.name, req.body.file, function(error, result, response) {
        if (error) {
            res.send(error);
            return;
        }
        res.send(result);
    });

}

However I am getting this error.

{
    "code": "ResourceNotFound",
    "statusCode": 404,
    "requestId": "bffa6099-0001-000b-53f9-80d18a000000"
}

回答1:

Couple of changes needed:

expiration date should be greater than start date.
shared access signature should use same container name.
shared access signature should be passed in file name, not file content.

After these changes, the code would be similar to this:

var sharedAccessSignatureToken = blobSvc.generateSharedAccessSignature('mycontainer', req.body.name, sharedAccessPolicy);
var sharedBlobService = azure.createBlobServiceWithSas(blobSvc.host, sharedAccessSignatureToken);

sharedBlobService.createBlockBlobFromText('mycontainer', req.body.name, req.body.file, function(error, result, response) {
        if (error) {
            res.send(error);
            return;
        }
        res.send(result);
    });
