🔧 Usage

Build a GhostRequest

import Ghost

do {
    let request = try GhostRequest.builder("YOUR_URL")!
                .setAccept(.json)
                .setCache(.reloadIgnoringLocalCacheData)
                .setMethod(.PATCH)
                .setTimeout(20)
                .setJSONBody(["foo", "bar"])
                .setContentType(.json)
                .setServiceType(.background)
                .setCacheControls([.maxAge(500)])
                .setURLParameters(["foo": "bar"])
                .setAcceptEncodings([.gzip, .deflate])
                .setBasicAuthorization(user: "user", password: "password")
                .setHeaders(["foo": "bar"])
                .build()
} catch {
    print("Request error: \(error)")
}

Request asynchronously

import Ghost

let ghost = GhostURLSession()

ghost.data(URL(string: "YOUR_URL")!).async { (response, error) in
    do {
        if let object: [AnyHashable: Any] = try response?.object() {
            print("Response dictionary: \(object)")
        } else if let error = error {
            print("Net error: \(error)")
        }
    } catch {
        print("Parse error: \(error)")
    }
}

Request synchronously

import Ghost

let ghost = GhostURLSession()

do {
    let object: [AnyHashable: Any] = try ghost.data("YOUR_URL").sync().object()
    print("Response dictionary: \(object)")
} catch {
    print("Error: \(error)")
}

Request from cache

import Ghost

let ghost = GhostURLSession()

do {
    let object: [AnyHashable: Any] = try ghost.data("YOUR_URL").cached().object()
    print("Response dictionary: \(object)")
} catch {
    print("Error: \(error)")
}

Track progress

import Ghost

let ghost = GhostURLSession()

do {
    let task = try ghost.data("YOUR_URL").progress({ progress in
        print(progress)
    }).sync()
} catch {
    print("Error: \(error)")
}

Add interceptors for all requests

import Ghost

let ghost = GhostURLSession()

ghost.addRequestInterceptor { request in
    request.addHeader("foo", value: "bar")
    request.setBearerAuthorization(token: "token")
    return request
}

Retry requests

import Ghost

let ghost = GhostURLSession()

ghost.retryClosure = { response, _, _ in response?.statusCode == XXX }

do {
    let task = try ghost.data("YOUR_URL").retry({ response, error, retryCount in
        return retryCount < 2
    }).sync()
} catch {
    print("Error: \(error)")
}

🧙‍♂️ Codable

Encodable

import Ghost

let request = GhostRequest.builder("YOUR_URL")!
            .setJSONObject(Encodable())
            .build()

Decodable

import Ghost

let ghost = URLSession()

do {
    let object: Decodable = try ghost.data("YOUR_URL").sync().decode()
    print("Response object: \(object)")
} catch {
    print("Error: \(error)")
}

🌙 GhostHunter

let url = URL.init(string: "YOUR_URL")!
do {
    try GhostHunter.async(.GET, url: url, parameters: ["name": "elias"], headers: ["Content-Type": "text/json"], progress: { (pregress) in
        print(pregress)
    }, completion: { (response, error) in
        do {
            if let result: SomeCodableType = try response?.decode() {
                print("GhostHunter Asynchronous: \(result)")
            } else if let error = error {
                print("GhostHunter Asynchronous: Ghost error: \(error)")
            }
        } catch {
            print("GhostHunter: Parse error: \(error)")
        }
    }
} catch {
    print("GhostHunter: Request error: \(error)")
}
