How to access s3 bucket files via REST API with AWS signature Authentication in Thingworx

[VV_10743662]

Hi Folks,

I am trying to access the file stored in s3 bucket in Thingworx via the AWS signature authentication. But I am unable to access the file. I tried to pass the AWS signature in the Header in below format:

let header = {
             "Authorization": {

                             "AccessKey": + accessKey,
                             "SecretKey": + secretKey
                             }
               };

let params = {

proxyScheme: undefined /* STRING {"defaultValue":"http"} */,

headers: header,

ignoreSSLErrors: undefined /* BOOLEAN */,

useNTLM: undefined /* BOOLEAN {"defaultValue":false} */,

workstation: undefined /* STRING {"defaultValue":""} */,

useProxy: undefined /* BOOLEAN {"defaultValue":false} */,

proxyHost: undefined /* STRING {"defaultValue":""} */,

url: "http://localhost:9000/bucket1/"+fileName /* STRING */,

timeout: undefined /* NUMBER {"defaultValue":60} */,

proxyPort: undefined /* INTEGER {"defaultValue":8080} */,

password: undefined /* STRING */,

domain: undefined /* STRING {"defaultValue":""} */,

username: undefined /* STRING */

};

// result: IMAGE

let result = Resources["ContentLoaderFunctions"].LoadImage(params);

I am getting the below error: :JSON does not allow non-finite numbers.

Can somebody tell me what is wrong in my request or how to pass the AWS signature while making a REST call?

Thanks in advance.

Unfortunately it's more complex than that. AWS requires you to sign REST requests, see https://docs.aws.amazon.com/AmazonS3/latest/API/RESTAuthentication.html. It won't allow you pass your secret key in HTTP header. Long story short, you have to use a proper AWS client. I'm not aware of any public AWS S3 extensions, although every ThingWorx developer seems to have written at least one in scope of some commercial project. Unless you are lucky and find one, you'd need to implement it yourself.
