我正在创建一项功能，允许您在 iOS 设备和本地网络中的其他计算机之间共享图片。
当我向套接字写入数据时遇到了问题，但直到我关闭连接后数据才被传送。据我所知应该有类似 flush() 方法。因为它的行为就像我断开连接时发生的那样。
因此，如果有人可以为该问题提供帮助或提出更好的解决方案，那就完美了。
这是我的经理类:
import CocoaAsyncSocket
class CollaborationSocketConnectionService: NSObject, GCDAsyncSocketDelegate {
static let shared = CollaborationSocketConnectionService()
var tcpSocket: GCDAsyncSocket?
private var ipAddress = ""
private var port = 0
private var guid = String()
override init() {
super.init()
tcpSocket = GCDAsyncSocket(delegate: self, delegateQueue: DispatchQueue.main)
guid = UUID().uuidString.lowercased()
}
// MARK: - General Functions
func connectToSocket(at ip: String, port: Int) {
self.ipAddress = ip
self.port = port
do {
try tcpSocket?.connect(toHost: ip, onPort: UInt16(port), withTimeout: -1)
} catch let error {
print("Cannot open socket to \(ip):\(port): \(error)")
tcpSocket = nil
}
}
func disconnect() {
tcpSocket?.disconnect()
}
func sendImage(image: UIImage?) {
if !(tcpSocket?.isConnected ?? false) {
try? tcpSocket?.connect(toHost: self.ipAddress, onPort: UInt16(self.port), withTimeout: -1)
}
guard let data = image?.jpegData() else {return}
let base64Image = data.base64EncodedString()
let imageModel = UploadImage(contentLength: 666, command: "UploadImage", uuid: guid, imageData: ImageData(fileSize: base64Image.count, fileGuid: UUID().uuidString.lowercased(), blocksCount: 1, blockIndex: 0, blockLength: base64Image.count, data: base64Image))
let encoder = JSONEncoder()
let jsonData = try? encoder.encode(imageModel)
self.tcpSocket?.write(jsonData!, withTimeout: 10, tag: 1)
}
// MARK: - GCDAsyncSocketDelegate
func socket(_ sock: GCDAsyncSocket, didConnectToHost host: String, port: UInt16) {
print("connected")
sock.readData(withTimeout: -1, tag: 0)
}
func socket(_ sock: GCDAsyncSocket, didWritePartialDataOfLength partialLength: UInt, tag: Int) {
if tag == 0 {
print("written")
}
}
func socket(_ sock: GCDAsyncSocket, didWriteDataWithTag tag: Int) {
if tag == 0 {
print("First Chunk sent")
// self.tcpSocket?.disconnect()
// self.tcpSocket?.perform {
// self.tcpSocket?.disconnectAfterWriting()
// }
// self.connectToSocket(at: self.ipAddress, port: self.port)
}
if tag == 1 {
print("Second Chunk sent")
}
if tag == 99 {
print("KEK")
}
}
func socket(_ sock: GCDAsyncSocket, didReadPartialDataOfLength partialLength: UInt, tag: Int) {
print(partialLength)
}
func socket(_ sock: GCDAsyncSocket, didRead data: Data, withTag tag: Int) {
let stringFromServer = String(bytes: data, encoding: .utf8)
print("READED DATA \(stringFromServer!)")
}
func socketDidDisconnect(_ sock: GCDAsyncSocket, withError err: Error?) {
print("DISCONNECTED")
}
最佳答案
然后我找到了解决方案。 只需在消息末尾添加“\n”...
let jsonDataString = String(bytes: try! encoder.encode(imageModel), encoding: .utf8)! + "\n"
let jsonData = jsonDataString.data(using: .ascii)
