我正在尝试从我的 iphone 模拟器打开一个套接字连接，并将一个简单的 NSString 发送到我在端口 80 中使用 java 设置的本地主机服务器。
我遇到的问题是，当我在 NSOutputStream 上写入数据时，服务器不会接收到它，直到我关闭模拟器。然后服务器接收到数据并抛出此异常 java.net.SocketException: Broken pipe
我知道与关闭 NSOutputStream 和刷新有关，但是如何在 Objective c 中实现这一点？
我在我的初始 ViewController 中调用 ProtocolCommunication，如下所示：
protocol = [[ProtocolCommunication alloc] init];
[protocol initNetworkCommunication];
[protocol sendData];
协议通信类 (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();
}
有任何想法吗？？
