所以我在
Swift中使用套接字并试图将应用程序与我的服务器连接起来.我让应用程序连接到服务器的IP地址,并在服务器上使用netcat进行测试.在执行期间,应用程序的控制台输出显示它已成功连接到服务器.但是,流委托似乎没有响应.当我输入netcat时,app控制台没有打印任何内容.我已经搜索了很长一段时间,发现我的实现与其他实现非常相似.也许我在这里遗漏了一些我看不到的东西.
任何想到这个问题的人都将不胜感激！
代码如下：
import UIKit
class ViewController: UIViewController,StreamDelegate {
let addr:String = "52.34.56.78"
let port:Int = 1234
var inputStream: InputStream?
var outputStream: OutputStream?
override func viewDidLoad() {
super.viewDidLoad()
self.connect(host: addr,port: port)
}
func connect(host: String,port: Int) {
Stream.getStreamsToHost(withName: host,port: port,inputStream: &inputStream,outputStream: &outputStream)
if inputStream != nil && outputStream != nil {
inputStream!.delegate = self
outputStream!.delegate = self
inputStream!.schedule(in: RunLoop.main,forMode: RunLoopMode.defaultRunLoopMode)
outputStream!.schedule(in: RunLoop.main,forMode: RunLoopMode.defaultRunLoopMode)
inputStream!.open()
outputStream!.open()
print("successfully connected")
}
else {
print("connection unsuccessful")
}
}
func stream(aStream: Stream,handleEvent eventCode: Stream.Event) {
if aStream === inputStream {
switch eventCode {
case Stream.Event.errorOccurred:
print("input: ErrorOccurred: \(aStream.streamError?.localizedDescription)")
break
case Stream.Event.openCompleted:
print("input: OpenCompleted")
break
case Stream.Event.hasBytesAvailable:
print("input: HasBytesAvailable")
break
default:
break
}
}
else {
print("unknown stuff happened")
}
}
}
