S3 Presign URL: (MISSING) Values

[krak3n]

Hi

When attempting to generate a pre-signed s3 get object url the generated url contains (MISSING) values:

https://s3-eu-west-1.amazonaws.com/bucket.name/key?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=ACCESS_KEY%!F(MISSING)20161017%!F(MISSING)eu-west-1%!F(MISSING)s3%!F(MISSING)aws4_request&X-Amz-Date=20161017T110116Z&X-Amz-Expires=60&X-Amz-SignedHeaders=host%!B(MISSING)x-amz-content-sha256&X-Amz-Signature=SIGNATURE

How I'm calling it:

    svc := s3.New(session.New(&aws.Config{
        Region:           aws.String("eu-west-1"),
        Credentials: credentials.NewCredentials(&credentials.StaticProvider{
            Value: credentials.Value{
                AccessKeyID:     "my-access-key",
                SecretAccessKey: "my-secret-key",
            },
        }),
    }))
    req, out := svc.GetObjectRequest(&s3.GetObjectInput{
        Bucket: aws.String("bucket.name"),
        Key:    aws.String("key"),
    })
    urlStr, err := req.Presign(time.Second * 60)

I don't really know what I am doing wrong so any help would be much appreciated 😄

Thanks,

Chris

Meh ignore me, ended up being a problem with my out put of the URL.

Not to necro this 3 years later, but for those of us doing programming before our morning cups of coffee: don't Printf your URLs. :)

I just stepped in the very same thing. I was outputting the URL using my Go logging, which is Printf based, and grabbing the URL from the log for testing, it was full of "!FMISSING" stuff. When I printed the URL using fmt.Println(url), everything is fine. Pure testing problem.

Or to be clearer, don't print the url as the formatting string.
