如何从 HTTP-auth 保护区获取图像？
我有一个网络摄像头（D-LINK DCS-2130）和一个网站。相机没有“访客”选项（或者我没有找到它在哪里？），所以我需要授权我的网站显示来自相机的图像。显示图像的正确方法是什么？
我有 2 个想法：
- 创建 getImage.php，它将向相机发送 login+pass(cURL) 并 获取图像。在我网站的代码中，我将使用
src="getImage.php" - 创建相同的 getImage.php，它将发送登录+pass(cURL)，获取图像，将其本地存储到
/ myCameraSnapshots/Image.jpgwait()1 秒，然后获取新图像并在本地覆盖它。
第一种方式将对摄像机执行许多请求（1 个观看者 - 1 个请求），第二种方式将加载我服务器的 CPU，但不会干扰摄像机的授权。
我希望你可以说“你是个白痴！有一种简单的方法可以从受保护的文件夹中获取图像！只需执行...”;)
I have a web-camera(D-LINK DCS-2130) and a web-site. Camera haven't "guest" option(or I haven't found where is it?), that so I need to authorize my site to show image from cam. What is a correct way to display an image?
I have 2 ideas:
- Create getImage.php, which will send login+pass(cURL) to the camera and
get the image. In my site's code I'll usesrc="getImage.php" - Create same getImage.php, which will send login+pass(cURL), get the image, store it localy into
/myCameraSnapshots/Image.jpgwait()1 second, then get new image and overwrite it localy.
The first way will do many requests to the camera (1 viewer — 1 request), second will get load my server's CPU, but will not disturb camera's authorization.
I hope You can say "You're an idiot! There's a easy way to get image from protected folder! Just do..." ;)

假设您在 getImage.php 中进行了正确的授权，则第二种方法（使用缓存）可能会更有效。
如果
getImage.php使用Content-Type标头，则只需将/myCameraSnapshots置于 Web 服务器根目录之外（或将其限制为本地访问）仅），然后根据需要使用readfile在调用时转储内容。根据相机上图像更改的频率，您还需要一种方法来使缓存的图像失效（可能通过删除它），这应该提示
getImage.php再次请求它从相机。Assuming that you are doing proper authorization in
getImage.php, the second method (using a cache) will likely be more efficient.If
getImage.phpuses aContent-Typeheader, then simply place/myCameraSnapshotsout of the web server root (or restrict it to local access only), and then usereadfileas needed to dump the contents when called.Depending on how often the image(s) on the camera change, you will need a method to invalidate the cached image as well (perhaps by deleting it), which should prompt
getImage.phpto request it again from the camera.我找到了该相机的访客密码（访客：访客），所以我的问题解决了，但无论如何每个人都应该阅读答案，在其中您可以找到您的问题的答案！
I've found guest's password for this camera (guest:guest), so my problem solved, but anyway everyone should to read answers, in them You can find answers to Your questions!
