如何在ios客户端连接socket.io 1.0？ 我还使用以下代码使用iOS流类进行连接： -
- (void) initNetworkCommunication {
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (__bridge CFStringRef)(@"23.236.52.90"), 3000 , &readStream, &writeStream);
_inputStream = (__bridge_transfer NSInputStream *)readStream;
_outputStream = (__bridge_transfer NSOutputStream *)writeStream;
[_inputStream setDelegate:self];
[_outputStream setDelegate:self];
[_inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[_outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[_inputStream open];
[_outputStream open];
}
- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent {
NSLog(@"stream event %i", streamEvent);
switch (streamEvent) {
case NSStreamEventOpenCompleted:
NSLog(@"Stream opened");
break;
case NSStreamEventHasBytesAvailable:
if (theStream == _inputStream) {
uint8_t buffer[1024];
unsigned int len;
while ([_inputStream hasBytesAvailable]) {
len = [_inputStream read:buffer maxLength:1024];
if (len) {
NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];
if (nil != output) {
NSLog(@"server said: %@", output);
[self messageReceived:output];
}
}
}
}
break;
case NSStreamEventErrorOccurred:
NSLog(@"Can not connect to the host!");
break;
case NSStreamEventEndEncountered:
[theStream close];
[theStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
theStream = nil;
break;
default:
NSLog(@"Unknown event");
}
}
虽然我收到包含数据的缓冲区，但我总是将len视为0。我的服务器使用socket.io 1.1.0。
缓冲响应： -
