问题描述

我只是想通过嵌入式服务器应用程序使用下面的代码下载mp4文件;



http：/ / videovlt是位于虚拟PC下的服务器应用程序。以下代码在我的电脑上运行的嵌入式服务器应用程序上运行。



spath =http：// videovlt / videos / 7bf9d10b-4006-4b44- 9626-e3751df2f4ce.mp4

fpath =E：\ videos\7bf9d10b-4006-4b44-9626-e3751df2f4ce.mp4

Hi,
I just simply want to download an mp4 file via embedded server application using the code below;

http://videovlt is server application which is located under virtual pc. and the code below runs on an embedded server application which is running under my pc.

spath = "http://videovlt/videos/7bf9d10b-4006-4b44-9626-e3751df2f4ce.mp4"
fpath = "E:\videos\7bf9d10b-4006-4b44-9626-e3751df2f4ce.mp4"

webClient.DownloadFile(spath, fpath);

但它给出了远程服务器返回错误：（500）内部服务器错误。

错误！

这是什么原因？

我尝试添加这个但是没有工作;

webClient.Headers.Add（用户代理，Mozilla / 5.0（Windows; U; MSIE 9.0; Windows NT 9.0; en-US））;

But it gives "The remote server returned an error: (500) Internal Server Error."
error!
What is the reason for this?
I tried adding this but didn't work;
webClient.Headers.Add("user-agent", "Mozilla/5.0 (Windows; U; MSIE 9.0; Windows NT 9.0; en-US)");

推荐答案

问题是源mp4 url​​在被嵌入式服务器占用之前被破坏了。

The problem was source mp4 url was getting broken before consumed by embedded server.
