如何从CVPixelBufferRef获取RGB(或任何其他格式)像素值？我尝试了很多方法,但还没有成功.

func captureOutput(captureOutput: AVCaptureOutput!,
                   didOutputSampleBuffer sampleBuffer: CMSampleBuffer!,
                   fromConnection connection: AVCaptureConnection!) {
  let pixelBuffer: CVPixelBufferRef = CMSampleBufferGetImageBuffer(sampleBuffer)!
                CVPixelBufferLockBaseAddress(pixelBuffer, 0)
  let baseAddress = CVPixelBufferGetBaseAddress(pixelBuffer)

  //Get individual pixel values here

  CVPixelBufferUnlockBaseAddress(pixelBuffer, 0)
}

我正在使用注入 cookie 的脚本初始化 WKWebView。该脚本具有以下形式：

document.cookie = 'mycookie=2bxxx962-b525-4afb-88de-ae4f12ecaxxxx;domain=stage.site.com;path=/;expires=Fri, 10 Apr 2020 21:32:50 GMT';

但是，在我加载一个 url 并检查 cookie 之后，cookie 有一个 domain=".stage.site.com"

Does someone know why the dot is being added? This is causing problems downstream as I now have duplicate cookies.
