我知道SHA-1是首选,但这个项目要求我使用MD5.
#include <openssl/md5.h>
- (NSString*) MD5Hasher: (NSString*) query {
NSData* hashed = [query dataUsingEncoding:NSUTF8StringEncoding];
unsigned char *digest = MD5([hashed bytes], [hashed length], NULL);
NSString *final = [NSString stringWithUTF8String: (char *)digest];
return final;
}
我从StackOverflow上的另一个类似问题的答案得到了这个代码,但是当程序在返回final时中断时,我从GDB得到以下错误;
(gdb) p digest
$1 = (unsigned char *) 0xa06310e4 "\0206b\260/\336\316^\021\b\a/9\310\225\204"
(gdb) po final
Cannot access memory at address 0x0
(gdb) po digest
Program received signal EXC_BAD_ACCESS, Could not access memory.

The program being debugged …我正在尝试根据本教程在我的应用程序中实现NotificationListenerService:http://www.kpbird.com/2013/07/android-notificationlistenerservice.html,但是在调用getActiveNotifications时我遇到了NullPointerException.

我正在向服务发送广播,该广播应生成所有通知的列表:
private void activeNot () {
List l = new List();
l.Initialize();
for (StatusBarNotification sbn : getActiveNotifications() ) { <---- Error happens here
l.Add(sbn);
}
Log.i("B4A", "List created.");
}
}
这是我生成SSL证书,密钥等的方式:
openssl genrsa -out server.key 1024
openssl rsa -in server.key -out new_key.pem
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 10000 -in server.csr -signkey new_key.pem -out server.crt
这有效,我可以看到chrome的输出,虽然我得到一个警告,我将首先得到病毒.
openssl s_server -cert server.crt -www -key new_key.pem
这是服务器的一个片段.我会说实话,我不确定每条线路到底在做什么,尽管我有个好主意:
socketFactory->server(true); // this is the server
socketFactory->authenticate(false); // no auth?
socketFactory->loadCertificate("server.crt");
socketFactory->loadPrivateKey("new_key.pem");
客户:
socketFactory->loadTrustedCertificates("server.crt");
socketFactory->authenticate(true); //auth? wierd, right? This guy does this:[1]
[1] http://permalink.gmane.org/gmane.comp.lib.thrift.user/1651
如果我loadTrustedCertificates在客户端注释掉,那么我将获得SSL未经验证的证书例外.留下该行,我得到一个auth失败异常.
这里有两个更长的代码片段,它们将上述片段放在更好的视角中.
服务器:
shared_ptr<SkullduggeryHandler> handler(new SkullduggeryHandler());
shared_ptr<TBufferedTransportFactory> transportFactory =
shared_ptr<TBufferedTransportFactory>(new TBufferedTransportFactory());
shared_ptr<TProtocolFactory> protocolFactory(new TBinaryProtocolFactory());
shared_ptr<TProcessor> …它只是坐在那里......我如何独立于UI动作运行代码(如同,不仅仅是响应按钮按下)？我正在尝试初始化一些对象并在唤醒.FromNib之前运行一些脚本.我该怎么做呢？
的main.m
#import <Cocoa/Cocoa.h>
int main(int argc, char *argv[])
{
return NSApplicationMain(argc, (const char **) argv);
}
CoolClass.h
#import <Cocoa/Cocoa.h>
@interface CoolClass : NSObject <NSApplicationDelegate> {
}
- (void) applicationDidFinishLaunching : (NSNotification *) aNotification;
@end
CoolClass.m
#import "CoolClass.h"
@implementation CoolClass
- (void) applicationDidFinishLaunching : (NSNotification *) aNotification {
NSLog(@"THIS SHOULD BE PRINTED TO THE DEBUG CONSOLE");
}
@end
我也试过"applicationWillFinishLaunching",但仍然没有运气.任何帮助都将不胜感激.谢谢.
我知道任务返回一个标准错误的值,我可以通过输入"echo $？"看到 在手动运行任务后在终端中.
现在这段代码:
[aTask launch];
[aTask waitUntilExit];
int status = [aTask terminationStatus];
看起来不错,但gdb说状态是0x0的位置,无法访问.有人知道Xcode中NSTask对象中的任何错误吗？难道我做错了什么？
谢谢你的回复.
