语音通信原理

客户端代码是这样的。。。

#import "ViewController.h" 

@implementation ViewController 

-(void)aaa:(UIButton *)btn 
{ 
    NSString *method=[NSString stringWithFormat:@"login"]; 
    NSString *username=[NSString stringWithFormat:@"123"]; 
    NSString *password=[NSString stringWithFormat:@"123"]; 
    NSString *urlString= [NSString stringWithFormat:@"http://192.168.1.107:8080/ipTest/test.do?%@%@&%@%@&%@%@",@"method=",method,@"username=",username,@"password=",password]; 
   
    ASIFormDataRequest *requestForm = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:urlString]]; 
    //设置需要POST的数据，这里提交两个数据，A=a&B=b 
    //[requestForm setPostValue:@"a" forKey:@"A"]; 
    //[requestForm setPostValue:@"b" forKey:@"B"]; 
    [requestForm startSynchronous]; 
     
    //输入返回的信息 
    NSLog(@"response\n%@",[requestForm responseString]); 
    [requestForm release]; 
} 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    button1=[[UIButton alloc]initWithFrame:CGRectMake(200, 200, 50, 50)]; 
    button1.backgroundColor=[UIColor redColor]; 
    [self.view addSubview:button1]; 

    [button1 addTarget:self action:@selector(aaa:) forControlEvents:UIControlEventTouchUpInside]; 
// Do any additional setup after loading the view, typically from a nib. 

} 

- (void)viewDidUnload 
{ 
    [super viewDidUnload]; 
    // Release any retained subviews of the main view. 
} 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); 
} 

@end 

客户端想要访问服务器 必须加上服务器的ip 服务端我是这样实现的。。。 
服务器是用java开发的 
public void doLogin(HttpServletRequest request,HttpServletResponse response) throws IOException{ 
  String username=request.getParameter("username"); 
  String password=request.getParameter("password"); 
  String getStr=request.getParameter("A"); 
  System.out.println("用户名:"+username+ "密码:"+password); 
  getAddr(request); 
  PrintWriter out=response.getWriter(); 
  String msg=null; 
  if(username!=null&&username.equals("123")&&password!=null &&password.equals("123")&& getStr!=null&&getStr.equals("a")){ 
   msg="登陆成功";
