API

✢ Notes

  • API is two-way in the most of time.

  • Use closure is a easy way to control the response from API.

    func requestAPI(api: String, param: [String: Any], success: @escaping (NSDictionary?) -> Void, fail: @escaping (NSDictionary) -> Void) {

    guard let url = URL(string: api) else {
        NSLog("%@ is not exist !", api)
        return
    }

    var request = URLRequest(url: url)
    let data = JSON(param) //Dictionary -> JSON
    var requestData = ""

    //prepare request data (follow the API request define)
    requestData = ...
    ...

    //set-up API connection (follow the API request define)
    request.httpBody = requestData.data(using: .utf8, allowLossyConversion: true)
    request.timeoutInterval = 30
    request.httpMethod = "POST"
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")

    //send request
    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
        guard error == nil else {
            NSLog("Session error: %@", String(describing: error))
            return
        }

        //parse response
        if let dict = DICT(data!) { //JSON -> Dictionary
            if success {
                success(data)
            } else {
                fail(data)
            }
        }
    }
    task.resume()
}
