⑶ ios 如何实现 DAPP

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"];
笭肠蒂段郦灯垫犬叮华 NSString *password=[NSString stringWithFormat:@"123"];
NSString *urlString= [NSString stringWithFormat:@"",@"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):(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != );
}
@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";
}
else
{
msg="登陆失败";
}

out.print(msg);
out.flush();
out.close();
}

⑸ Ubuntu Linux设置守护进程时出错的解决

Ubuntu系统使用源从7.10升级到8.04后，启动并在用户登录后，界面无响应5分钟左右后，弹出出错信息：

启动GNOME设置守护进程时出错

主题、声音或者背景设置等可能不会正常工作。

最后的错误信息是：

Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

GNOME在您下次登录时仍将试图重启动设置守护进程

解决方法：

在启动至将要登陆到用户桌面时， 按Ctrl + Alt + F1 进入命令行模式，作如下修改：

sudo vim /etc/network/interfaces

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet dhcp

注意“eth0”最后一个字为零，而非英文字母“欧”，完成键盘输入后，按ESC，输入：

wq！

保存并退出文件的修改，使用如下命令重新启动网络服务:

sudo /etc/init.d/networking restart

或者:

sudo ifdown eth0

或者:

sudo ifup eth0

重启系统，发现问题已经解决，锐捷要求的动态ip也可以获取到，可顺利上线了。

⑹ 中译英：如果你继续阻止我向ETH反映问题

如果你继续阻止我向ETH反映问题
If you continue to prevent me from reporting the problem to ETH

我将向道德办公室，反映你的职业道德问题，不调查和阻止我向其他人反映问题的权利。以及导致的一切后果，你无权阻止我。

I will report your ethical issues to the moral office, that you did not investigate and that you deprived me of the right to report the problems elsewhere. Also the result that this brings, you have no right to stop me.

⑺ EOS魔方到底啥意思

EOS，可以理解为Enterprise Operation System，即为商用分布式应用设计的一款区块链操作系统。EOS是引入的一种新的区块链架构，旨在实现分布式应用的性能扩展。注意，它并不是像比特币和以太坊那样的货币，而是基于EOS软件项目之上发布的代币，被称为区块链3.0。 EOS的主要特点如下：
1.EOS有点类似于微软的windows平台，通过创建一个对开发者友好的区块链底层平台，支持多个应用同时运行，为开发dAPP提供底层的模板。
2.EOS通过并行链和DPOS的方式解决了延迟和数据吞吐量的难题，EOS是每秒可以上千级别的处理量，而比特币每秒7笔左右，以太坊是每秒30-40笔；
3.EOS是没有手续费的，普通受众群体更广泛。EOS上开发dApp，需要用到的网络和计算资源是按照开发者拥有的EOS的比例分配的。当你拥有了EOS的话，就相当于拥有了计算机资源，随着DAPP的开发，你可以将手里的EOS租赁给别人使用，单从这一点来说EOS也具有广泛的价值。简单来说，就是你拥有了EOS，就相当于拥有了一套房租给别人收房租，或者说拥有了一块地租给别人建房。
