我试图打开从我的iPhone模拟器一个套接字连接,并发送一个简单的NSString我在端口设置与Java 80连接到Java socket服务器iPhone NSStreamDelegate问题
,我有一个问题,本地主机服务器当我在NSOutputStream上写入数据时,服务器没有收到它,直到关闭模拟器。然后服务器接收到数据,并引发这个异常java.net.SocketException:损坏的管道
我知道是关闭NSOutputStream和刷新相关的东西,但我怎么能在Objective C中实现这一点?
我这样调用在我最初的ViewController的ProtocolCommunication:
protocol = [[ProtocolCommunication alloc] init];
[protocol initNetworkCommunication];
[protocol sendData];
ProtocolCommunication类(IOS)
@implementation ProtocolCommunication
@synthesize inputStream, outputStream
- (void) initNetworkCommunication {
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"localhost", 80, &readStream, &writeStream);
inputStream = (NSInputStream *)readStream;
outputStream = (NSOutputStream *)writeStream;
[inputStream setDelegate:self];
[outputStream setDelegate:self];
//do the Looping
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inputStream open];
[outputStream open];
NSLog(@"INIT COMPLETE");
}
- (void) sendData {
NSString *response = @"HELLO from my iphone";
NSData *data = [[NSData alloc] initWithData:[response dataUsingEncoding:NSASCIIStringEncoding]];
[outputStream write:[data bytes] maxLength:[data length]];
}
Java服务器
String msgReceived;
try {
ServerSocket serverSocket = new ServerSocket(80);
System.out.println("RUNNING SERVER");
while (running) {
Socket connectionSocket = serverSocket.accept();
BufferedReader inFromClient = new BufferedReader(
new InputStreamReader(connectionSocket.getInputStream()));
DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());
msgReceived = inFromClient.readLine();
System.out.println("Received: " + msgReceived);
outToClient.writeBytes("Aloha from server");
outToClient.flush();
outToClient.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
任何想法?
