Environments

• Browser depends on window.crypto
• Nodejs >= v10.0

In the Nodejs environment, gRPC is supported and used by default, you can choose to close it, and still use Http to request

XuperSDK.getInstance({
    ...,
    env: {
        node: {
            disableGRPC: true // disable gRPC
        }
    }
})
