SignatureDoesNotMatch Error about react-s3-uploader HOT 7 CLOSED

For router.get('/test', ...), there would be no req.params[0], but I guess you aren't even using the params variable above.

In this example you posted, you are just doing an s3.listBuckets, so if that doesn't work, I'm not sure what the issue could be. Not sure this has anything to do with react-s3-uploader if you can't list buckets with this code.

It could be that you need to specify the region, but you may want to create an issue with aws-sdk.

I think i figured out the problem. Looks like there is an undocumented option getFileKeyDir that needs to be set as follows

app.use('/s3', require('react-s3-uploader/s3router')({
    getFileKeyDir: function(req) {return("folder")},
    bucket: "bucket"
}));

If getFileKeyDir is not set it defaults to a function that returns "."

This results in the Key param that is used in the getSignedUrl calls being set to "./"

The getSignedUrl call will then sign the url using that Key. However, the actual url that is used to GET the image will not have the "./" characters.So the URL's do not match, hence the signature matching error.

So, create at least one directory in the bucket, and have it as the return value in the getFileKeyDir function.

Ah, good catch. We should document that feature, but also return "" if not implemented. Thanks for the research.

Just put up a fix on branch fix-getFilKeyDir. Can you try it out in your application and see if it works as expected?

Add this to your package.json to test the branch:

...
"react-s3-uploader": "odysseyscience/react-s3-uploader#fix-getFilKeyDir",
...

Delete node_modules/react-s3-uploader first, then run npm install

If all looks good, I'll push an update to NPM.

Works for me. Thanks

For those of you may encountered this problem, make sure your stringToSign responsed by aws is the same to the API calculated.

Search for stringToSign and put breakpoint there to debug.
