How can I log each request/response using Alamofire?

Question

Is there a way to log each request / response using Alamofire (something similar to AFNetworkActivityLogger) ?

I am aware of Printable, DebugPrintable and Output (cU

Answer 1

In Alamofire 5.0.0 I used the answer based on: https://github.com/Alamofire/Alamofire/issues/2867#issuecomment-509662892 but I had to replace DataResponse by AFDataResponse. For example:

import Alamofire

final class AlamofireLogger: EventMonitor {

    func requestDidResume(_ request: Request) {

        let allHeaders = request.request.flatMap { $0.allHTTPHeaderFields.map { $0.description } } ?? "None"
        let headers = """
        ⚡️⚡️⚡️⚡️ Request Started: \(request)
        ⚡️⚡️⚡️⚡️ Headers: \(allHeaders)
        """
        NSLog(headers)


        let body = request.request.flatMap { $0.httpBody.map { String(decoding: $0, as: UTF8.self) } } ?? "None"
        let message = """
        ⚡️⚡️⚡️⚡️ Request Started: \(request)
        ⚡️⚡️⚡️⚡️ Body Data: \(body)
        """
        NSLog(message)
    }

    func request(_ request: DataRequest, didParseResponse response: AFDataResponse) {

        NSLog("⚡️⚡️⚡️⚡️ Response Received: \(response.debugDescription)")
        NSLog("⚡️⚡️⚡️⚡️ Response All Headers: \(String(describing: response.response?.allHeaderFields))")
    }
}

And then you can use it in the following way:

let session = Session(eventMonitors: [ AlamofireLogger() ])

As it has explained by 0xced in an aforementioned post.
