通过TCP发送JPEG NSData到Python服务器

我有一个拥有iOS客户端的Python tcp服务器。它能够发送数据和接收，我遇到的唯一问题可能是编码。我试图通过TCP发送JPEG到Python服务器，并将数据写入服务器上的JPEG。 jpeg不断腐败。通过TCP发送JPEG NSData到Python服务器

客户端的OBJ-C代码：

[self.stillImageOutput captureStillImageAsynchronouslyFromConnection:videoConnection 
                  completionHandler:^(CMSampleBufferRef imageDataSampleBuffer, NSError *error) { 

      NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageDataSampleBuffer]; 
      UIImage *image = [[UIImage alloc] initWithData:imageData]; 
                   iv = [[UIImageView alloc] initWithImage:image]; 


                   [iv setFrame:[[self view]frame]]; 





                   ConnectionManager *netCon = [ConnectionManager alloc]; 
                   conMan = netCon; 
                   [conMan initNetworkCommunication]; 



                   [conMan.outputStream write:(const uint8_t *)[imageData bytes] maxLength:[imageData length]]; 



     }];

这里是蟒（扭曲）的服务器代码：

from twisted.internet.protocol import Factory, Protocol 
from twisted.internet import reactor 

class IphoneChat(Protocol): 
    def connectionMade(self): 
     self.factory.clients.append(self) 
     print "clients are ", self.factory.clients 

    def connectionLost(self, reason): 
     self.factory.clients.remove(self) 

    def dataReceived(self, data): 
     file = open('test.jpeg','w') 

     file.write(data) 
     file.close() 


factory = Factory() 

factory.clients=[] 


factory.protocol = IphoneChat 
reactor.listenTCP(2000, factory) 
print "Iphone Chat server started" 
reactor.run()
