Azure blob sasToken “Signature did not match”

问题

I was trying to upload an image to azure blob storage using createBlockBlobFromLocalFile. And I created the sasToken like what azure-storage-node instructed here. Here's my code for upload.

module.exports = function(params) {

var config = require('../../config/secrets');
var fs = require('fs');
var azure = require('azure-storage');
var controllers = {};

var blobSvc = azure.createBlobService(config.BLOB_LINK, config.BLOB_KEY);


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

    var fstream;
    req.pipe(req.busboy);

    var startDate = new Date();
    var expiryDate = new Date(startDate);
    expiryDate.setMinutes(startDate.getMinutes() + 100);
    startDate.setMinutes(startDate.getMinutes() - 100);

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

    req.busboy.on('file', function (fieldname, file, filename) {

        fstream = fs.createWriteStream(__dirname + '/upload/' + filename);
        file.pipe(fstream);
        fstream.on('close', function () {

            var sharedAccessSignatureToken = blobSvc.generateSharedAccessSignature('resources', filename, sharedAccessPolicy);
            var sharedBlobService = azure.createBlobServiceWithSas(blobSvc.host, sharedAccessSignatureToken);
            console.log("sas", sharedAccessSignatureToken);

            sharedBlobService.createBlockBlobFromLocalFile(
                    'resources',
                    filename,
                    fstream.path,
                    function(error, result, response) {
                        if (error) {
                            res.send(error);
                            return;
                        }
                        res.send(result);
                    });
        });
    });
}

return controllers;

};

But Im getting this error on my frontend.

回答1:

Usually, when we occur this issue, which means the sasToken content dosen't match the resource we request on Azure Storage.

And on my side, your code works fine. So please double check whether you have created the container named resources on your Blob Storage.

As on my side, I only can reproduce your issue when I upload a blob to Azure Storage without a container has created previously.
