⑶ ios 如何實現 DAPP

客戶端代碼是這樣的。。。
#import "ViewController.h"
@implementation ViewController
-(void)aaa:(UIButton *)btn
{
NSString *method=[NSString stringWithFormat:@"login"];
NSString *username=[NSString stringWithFormat:@"123"];
笭腸蒂段酈燈墊犬叮華 NSString *password=[NSString stringWithFormat:@"123"];
NSString *urlString= [NSString stringWithFormat:@"",@"method=",method,@"username=",username,@"password=",password];

ASIFormDataRequest *requestForm = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:urlString]];
//設置需要POST的數據，這里提交兩個數據，A=a&B=b
//[requestForm setPostValue:@"a" forKey:@"A"];
//[requestForm setPostValue:@"b" forKey:@"B"];
[requestForm startSynchronous];

//輸入返回的信息
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
客戶端想要訪問伺服器
必須加上伺服器的ip 服務端我是這樣實現的。。。
伺服器是用java開發的
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("用戶名:"+username+
"密碼:"+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="登陸成功";
}
else
{
msg="登陸失敗";
}

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

⑸ Ubuntu Linux設置守護進程時出錯的解決

Ubuntu系統使用源從7.10升級到8.04後，啟動並在用戶登錄後，界面無響應5分鍾左右後，彈出出錯信息：

啟動GNOME設置守護進程時出錯

主題、聲音或者背景設置等可能不會正常工作。

最後的錯誤信息是：

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在您下次登錄時仍將試圖重啟動設置守護進程

解決方法：

在啟動至將要登陸到用戶桌面時， 按Ctrl + Alt + F1 進入命令行模式，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」最後一個字為零，而非英文字母「歐」，完成鍵盤輸入後，按ESC，輸入：

wq！

保存並退出文件的修改，使用如下命令重新啟動網路服務:

sudo /etc/init.d/networking restart

或者:

sudo ifdown eth0

或者:

sudo ifup eth0

重啟系統，發現問題已經解決，銳捷要求的動態ip也可以獲取到，可順利上線了。

⑹ 中譯英：如果你繼續阻止我向ETH反映問題

如果你繼續阻止我向ETH反映問題
If you continue to prevent me from reporting the problem to ETH

我將向道德辦公室，反映你的職業道德問題，不調查和阻止我向其他人反映問題的權利。以及導致的一切後果，你無權阻止我。

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，可以理解為Enterprise Operation System，即為商用分布式應用設計的一款區塊鏈操作系統。EOS是引入的一種新的區塊鏈架構，旨在實現分布式應用的性能擴展。注意，它並不是像比特幣和以太坊那樣的貨幣，而是基於EOS軟體項目之上發布的代幣，被稱為區塊鏈3.0。 EOS的主要特點如下：
1.EOS有點類似於微軟的windows平台，通過創建一個對開發者友好的區塊鏈底層平台，支持多個應用同時運行，為開發dAPP提供底層的模板。
2.EOS通過並行鏈和DPOS的方式解決了延遲和數據吞吐量的難題，EOS是每秒可以上千級別的處理量，而比特幣每秒7筆左右，以太坊是每秒30-40筆；
3.EOS是沒有手續費的，普通受眾群體更廣泛。EOS上開發dApp，需要用到的網路和計算資源是按照開發者擁有的EOS的比例分配的。當你擁有了EOS的話，就相當於擁有了計算機資源，隨著DAPP的開發，你可以將手裡的EOS租賃給別人使用，單從這一點來說EOS也具有廣泛的價值。簡單來說，就是你擁有了EOS，就相當於擁有了一套房租給別人收房租，或者說擁有了一塊地租給別人建房。
