Cocoa 和 Swift - 我想使用 Swift 4 和 Cocoa for Mac OS 应用程序进行简单的 REST API 调用

Question

任何人都可以建议我如何使用 Swift 4 和 Cocoa 为 Mac OS 应用程序进行 REST API 调用。我尝试了很多方法，但无法进行 api 调用。

这是代码:

func callAPI(){

    let AuthorizationToken = "Basic mykey="
    var request = URLRequest(url: URL(string: "http://myipaddress/api/Batch")!)
    request.httpMethod = "GET"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue(AuthorizationToken, forHTTPHeaderField: "Authorization")
    let session = URLSession.shared
    let task = session.dataTask(with: request, completionHandler: { data, response, error -> Void in
        //print(response!)
        do {
            let json = try JSONSerialization.jsonObject(with: data!)
            print(json)
            self.ApiValue.stringValue = "Success"
        } catch {
            print("error")
            self.ApiValue.stringValue = "Error"
        }
    })

    task.resume()

}

在 Xcode 11 .1 +

设置功能 - 在应用程序沙箱下 - 检查传入连接和传出连接:

您可以尝试使用此代码来检查您的 viewDidLoad:

override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        let session = URLSession.shared
        let url = URL(string: "https://pokeapi.co/api/v2/")!

        let task = session.dataTask(with: url) { data, response, error in

            if error != nil || data == nil {
                print("Client error!")
                return
            }


            do {
                let json = try JSONSerialization.jsonObject(with: data!, options: [])
                print(json)
            } catch {
                print("JSON error: \(error.localizedDescription)")
            }
        }

        task.resume()
    }
