}新建一个js对象类 JsEvent
public class JsEvent
{
public string getVideo()
{
return "http://***.**.*/video/test.mp4";//getImageStr("F:\\test.mp4");
}
public string getImageStr(String path)
{
String contentType = "";
try
{
var reg = @"[\s\S].+[\\/](.+\..+)";
var matches = Regex.Matches(path, reg);
//matches[0].Groups[1];
String fileName = matches[0].Groups[1].ToString();
String suffix = fileName.Substring(fileName.LastIndexOf(".") + 1, fileName.Length - (fileName.LastIndexOf(".") + 1));
if ("jpg".Equals(suffix, StringComparison.CurrentCultureIgnoreCase) || "jpeg".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:image/jpeg;base64,";
}
else if ("png".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:image/png;base64,";
}
else if ("aac".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:audio/aac;base64,";
}
else if ("mp3".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:audio/mpeg;base64,";
}
else if ("wav".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:audio/x-wav;base64,";
}
else if ("mp4".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:video/mp4;base64,";
}
else if ("ogv".Equals(suffix, StringComparison.CurrentCultureIgnoreCase))
{
contentType = "data:video/ogg;base64,";
}
using (FileStream fsRead = new FileStream(path, FileMode.Open))
{
int fsLen = (int)fsRead.Length;
byte[] heByte = new byte[fsLen];
int r = fsRead.Read(heByte, 0, heByte.Length);
string base64Str = Convert.ToBase64String(heByte);
return contentType + base64Str;
}
}
catch (IOException e)
{
throw;
}
}
/// <summary>
/// 将文件转换成二进制
/// </summary>
/// <param name="Path">文件路径</param>
/// <returns></returns>
public static byte[] ConvertToBinary(string Path)
{
FileStream stream = new FileInfo(Path).OpenRead();
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, Convert.ToInt32(stream.Length));
return buffer;
}
}然后前端调用
bound.getVideo()
我这里主要是实现客户端视频在网页上播放所以效果如下：
代码：
<template>
<video :src="videoSrc" controls="controls" width="500" height="400"></video>
</template>
<script>
export default {
data() {
return {
videoSrc: "",
};
},
created: function() {
this.getVideoPath();
},
methods: {
sdf(event, props) {
console.log(event, props);
},
getVideoPath() {
console.log(bound.getVideo());
this.videoSrc = bound.getVideo();
}
}
};
</script>效果：
