HomeBackend DevelopmentPHP TutorialPHP+FLASH 做了个在线摄像头拍照,怎么将图片保存在本地

    摄像头调用部分自己已经写好,因为拍摄的照片较多,现在想先把摄像头拍摄的照片保存在本地,然后用FTP上传,问题是照片拍好后,不知道怎么保存在本地,请各位给我个例子,思路也行,不胜感激!


回复讨论(解决方案)

先保存到web服务器,用户可以选择下载、删除、还是做个照册。从安全角度来想,浏览器应该不允许flash操作本机的文件。

   现在做的这个系统必须要摄像头进行拍照,我在网上找的例子都是存服务器里的,现在要存在本地,用FTP上传,应该怎么弄?做到这一步卡住了。

要么用javascript+html5来试试,要么直接上传入服务器,降低照片分辨率,一般640*480就够了,因为用户的摄像头分辨率大多数也就这么高,实时上传数据的速度还是可以接受的。
另外浏览器和Flash控件都是不允许读取本地文件系统的。

如果 Flash 不能做到读写本地文件,那么要用 Flash 还有何用?
js 都是可以的(只不过要弹出安全警告对话框)

使用JS需要什么函数?

应该只能存到服务器上,自动存到客户端电脑上应该不是很现实,可以用二楼的方法,需要点击下载再上传或者是直接用php的ftp功能从服务器上传到目的服务器,存到客户机上唯 一方法是从服务器上下载

一直学习php  菜鸟飘过

感觉上,楼主的思路似乎应该转换一下??flash把图片转成数据流(直接有类可以用的,如:JPGEncoder),然后提交给php保存就行了,flash是无法保存文件的(桌面项目--air除外)。
php保存文件就不难了
之前做过一个类似的项目,可惜找不到东西了,俺PHP菜,保存文件的方法是从度娘那找的

代码里面会涉及文件存储路径吧

   现在结贴,谢谢各位的回答,对我帮助很大。对于这个问题,我现在换了个方法,先单张保存在WEB服务器,然后在用FTP存到目的服务器。

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
