我正在使用USB蓝牙适配器在我的Raspberry Pi上使用BlueZ进行编程.我需要能够以编程方式连接到Arduino BT,问题是Arduino的蓝牙模块仍在使用传统配对,因此每当我尝试打开设备的套接字时,我都会得到一个Permission Denied.如何通过BlueZ发送PIN码来完成配对请求？
我按照以下指南使用DWM API创建自定义Aero Frame.
我的工作:
void CMainFrame::OnActivate(UINT nState,CWnd* pWndOther,BOOL bMinimized )
{
CFrameWnd::OnActivate(nState,pWndOther,bMinimized);
BOOL fDwmEnabled = FALSE;
if (SUCCEEDED(DwmIsCompositionEnabled(&fDwmEnabled)))
{
if(nState == WA_ACTIVE )
{
MARGINS margins ={-1};
HRESULT hr = DwmExtendFrameIntoClientArea(m_hWnd, &margins);
if (!SUCCEEDED(hr));
}
}
}
void CMainFrame::OnNcPaint(){
RECT rcClient;
GetWindowRect(&rcClient);
// Inform the application of the frame change.
SetWindowPos(
NULL,
rcClient.left, rcClient.top,
RECTWIDTH(rcClient), RECTHEIGHT(rcClient),
SWP_FRAMECHANGED);
CFrameWnd::OnNcPaint();
CDC* dc = GetWindowDC();
dc->FillSolidRect(0,0,RECTWIDTH(rcClient),RECTHEIGHT(rcClient),RGB(0,0,0));
}
LRESULT CMainFrame::OnNcHitTest(CPoint p)
{
LRESULT r ;
r = CFrameWnd::OnNcHitTest( p);
if(r == HTMINBUTTON || …我已经禁用了我的箭头键.vimrc,但......
如何在自动完成弹出窗口中上下导航？j并且k无法正常工作,因为我处于插入模式.
我正在开发一个dropwizard REST服务.我使用https://bitbucket.org/b_c/jose4j/wiki/Home在jwt中添加了身份验证
令牌必须进入Authorization标头
Authorization: Bearer [TOKEN]
我想找到一个很好的方法来添加一些swagger注释,以便在swagger-ui上拥有授权标头.
我找到了一个解决方法,隐藏了身份验证参数并添加了一个虚拟参数 @HeaderParam
@POST
@Path("/test/")
public Foo postBar(
@Auth @ApiParam(hidden = true) Principal user,
@ApiParam("data") Foo bar,
@HeaderParam(value="Authorization")String dummy)
这将添加到参数中:
{
"name" : "Authorization",
"in" : "header",
"required" : false,
"type" : "string"
}
如果我把@HeadParam对Principal user我得到的运行时间:
Caused by: org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] No injection source found for a parameter of type public java.util.Map com.foo.bar.AppResource.get(java.security.Principal) at index 0.; source='ResourceMethod{httpMethod=GET, consumedTypes=[], …当标签以"IMS"开头时,为什么Logcat不打印日志？

我找到了很多处理 Jersey 和 ssl 自签名证书的解决方案。Dropwizard 版本是 0.9.2
我试图设置 SSLContext 但我得到了
The method sslContext(SSLContext) is undefined for the type JerseyClientBuilder
代码：
TrustManager[] certs = new TrustManager[]{
new X509TrustManager() {
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
}
};
public static class TrustAllHostNameVerifier implements HostnameVerifier {
public boolean verify(String hostname, SSLSession session) {
return true;
}
} …我已阅读有关传递比较器的所有线程,我不明白为什么这个比较器函数违反了规则.如果有人可以清洁我的眼睛,我认为这很简单,但我无法得到它
堆栈是:
java.util.TimSort.mergeLo(TimSort.java:747)
java.util.TimSort.mergeAt(TimSort.java:483)
java.util.TimSort.mergeCollapse(TimSort.java:410)
我的对象(简化)
public class SleepDetails {
private DateTime time;
private SleepEnum type;
[...]
}
public enum SleepEnum {
DEEP(0), LIGHT(1), AWAKE(2), BEGIN(16), END(17);
[...]
}
比较器静态分为一类
Comparator<SleepDetails> comparator = new Comparator<SleepDetails>(){
public int compare(SleepDetails arg0, SleepDetails arg1) {
int res = arg0.getTime().compareTo(arg1.getTime());
if (res != 0)
return res;
if (arg0.getType() == arg1.getType())
return 0;
switch(arg0.getType()) {
case BEGIN:
return -1;
case END:
return 1;
default:
return 0;
}
}
};
主要是我希望按日期对事件进行排序,如果两个事件具有相同的日期时间,则将begin事件设置为first,将end事件设置为last.
