在Web应用程序中通过网络摄像头保存和上传图像 [英] save and upload images through webcam in web application

问题描述

如何在网络应用程序中通过网络摄像头保存和上传图像。请帮助。我试过这个代码，在本地机器上工作但是在托管之后，它没有在服务器上保存图像：



System.Drawing.Image originalimg;

string strFile = DateTime.Now.ToString（dd_MMM_yymmss）+.jpg;



FileStream log = new FileStream（Server.MapPath（strFile），FileMode.OpenOrCreate）;



byte [] buffer = new byte [1024] ;

int c;

while（（c = Request.InputStream.Read（buffer，0，buffer.Length））> 0）

{

log.Write（buffer，0，c）;

}

originalimg = System.Drawing.Image.FromStream（log ）;

originalimg = originalimg.GetThumbnailImage（320,240，new System.Drawing.Image.GetThumbnailImageAbort（ThumbnailCallback），IntPtr.Zero）;

来源alimg.Save（Server.MapPath（Images）+\\+ strFile）;

// @originalimg.Save（D：\\WebcamImages \\ + strFile）;

//写jpg文件名，由正则表达式拾取并显示在flash html页面上。

log.Close（）;

originalimg.Dispose（）;

File.Delete（Server.MapPath（strFile））;

Response.Write（../ Images /+ strFile） ; $ / b $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ h2_lin>解决方案

我也有这个问题，这个代码适用于localhost，但是当我发布应用程序时它不能工作...我尝试了很多并找到其他代码用于图像捕获，他们使用Jquery和javascript for webcam access ...它适用于我的应用程序。
