Moya: Basic Authentication w/ Base64 Encoding

[camcoding]

Environment: Swift 3 and Moya 8.0.1 and RxSwift.
Goal: I'm attempting to call a rest API that requires base64 encoded basic authentication.

I've attempted to use the CredentialsPlugin + URLCredential and pass the username/password but the rest API returned 401 (unauthorized). I wasn't able to determine if there's an option in that plugin to base64 encode the login credentials.

I can achieve this functionality using the Swift 3 URLSessionConfiguration + URLRequest objects by setting an HTTP request header that looks like this: "Authorization" : "Basic ". Here's a snippet of my Swift (non-Moya) code:

request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

I found a solution/work-a-round by adding a headers property to my TargetType extension and then returning an endpointClosure when initializing my provider.

I still think the CredentialsPlugin should have a configurable option to support base64 encoded login credentials.

I had to create a custom plugin to support basic auth. I might do a pull request to add this to Moya when I have time:

struct BasicAuthenticationPlugin: PluginType {
    let key: String

    func prepare(_ request: URLRequest, target: TargetType) -> URLRequest {
        let encodedKey = key.utf8Encoded.base64EncodedString(options: [])
        var request = request
        request.addValue("Basic " + encodedKey, forHTTPHeaderField: "Authorization")
        return request
    }
}

@yar1vn Check AccessTokenPlugin

@SeRG1k17 it didn't provide such functionality. thats why I am here too. Thanks @yar1vn, this solution works.

@ARGAMX back in the day we didn't support basic authentication, but since few releases the AccessTokenPlugin is capable of supporting both basic and bearer and custom types (e.g. JWT).
