netty vue 部署

Netty和Vue是两个不同的技术,Netty是一款高性能的网络通信框架,而Vue是一款流行的前端框架。它们之间并没有直接的部署关系。但是,我们可以通过将Vue打包成静态文件,然后将这些文件部署到Netty服务器上来实现Netty和Vue的部署。
具体步骤如下:
1. 在本地使用Vue CLI创建一个Vue项目,并编写前端代码。
2. 使用Vue CLI将Vue项目打包成静态文件。
3. 将打包后的静态文件复制到Netty服务器的静态资源目录下。
4. 在Netty服务器上编写代码,实现对静态资源的访问和处理。
5. 启动Netty服务器,访问静态资源的URL,即可看到Vue前端页面。
下面是一个简单的示例代码,用于在Netty服务器上实现对静态资源的访问和处理:
```java
public class StaticResourceHandler extends SimpleChannelInboundHandler<FullHttpRequest> {
private final String staticResourcePath;
public StaticResourceHandler(String staticResourcePath) {
this.staticResourcePath = staticResourcePath;
}
@Override
protected void channelRead0(ChannelHandlerContext ctx, FullHttpRequest request) throws Exception {
if (!request.decoderResult().isSuccess()) {
sendError(ctx, HttpResponseStatus.BAD_REQUEST);
return;
}
if (request.method() != HttpMethod.GET) {
sendError(ctx, HttpResponseStatus.METHOD_NOT_ALLOWED);
return;
}
String uri = request.uri();
String path = sanitizeUri(uri);
if (path == null) {
sendError(ctx, HttpResponseStatus.FORBIDDEN);
return;
}
File file = new File(staticResourcePath + File.separator + path);
if (file.isHidden() || !file.exists()) {
sendError(ctx, HttpResponseStatus.NOT_FOUND);
return;
}
if (!file.isFile()) {
sendError(ctx, HttpResponseStatus.FORBIDDEN);
return;
}
RandomAccessFile randomAccessFile = new RandomAccessFile(file, "r");
long fileLength = randomAccessFile.length();
HttpResponse response = new DefaultHttpResponse(HttpVersion.HTTP_1_1, HttpResponseStatus.OK);
HttpUtil.setContentLength(response, fileLength);
setContentTypeHeader(response, file);
setDateAndCacheHeaders(response, file);
if (HttpUtil.isKeepAlive(request)) {
response.headers().set(HttpHeaderNames.CONNECTION, HttpHeaderValues.KEEP_ALIVE);
}
ctx.write(response);
ChannelFuture sendFileFuture;
ChannelFuture lastContentFuture;
if (ctx.pipeline().get(SslHandler.class) == null) {
sendFileFuture = ctx.write(new DefaultFileRegion(randomAccessFile.getChannel(), 0, fileLength), ctx.newProgressivePromise());
lastContentFuture = ctx.writeAndFlush(LastHttpContent.EMPTY_LAST_CONTENT);
} else {
sendFileFuture = ctx.writeAndFlush(new HttpChunkedInput(new ChunkedFile(randomAccessFile, 0, fileLength, 8192)), ctx.newProgressivePromise());
lastContentFuture = sendFileFuture;
sendFileFuture.addListener(new ChannelProgressiveFutureListener() {
@Override
public void operationProgressed(ChannelProgressiveFuture future, long progress, long total) {
if (total < 0) {
System.err.println("Transfer progress: " + progress);
} else {
System.err.println("Transfer progress: " + progress + " / " + total);
}
}
@Override
public void operationComplete(ChannelProgressiveFuture future) {
System.err.println("Transfer complete.");
}
});
}
sendFileFuture.addListener(ChannelFutureListener.CLOSE);
}
private static final Pattern INSECURE_URI = Pattern.compile(".*[<>&\"].*");
private String sanitizeUri(String uri) {
try {
uri = URLDecoder.decode(uri, "UTF-8");
} catch (UnsupportedEncodingException e) {
try {
uri = URLDecoder.decode(uri, "ISO-8859-1");
} catch (UnsupportedEncodingException e1) {
throw new Error();
}
}
if (!uri.startsWith(staticResourcePath)) {
return null;
}
if (!uri.startsWith("/")) {
return null;
}
uri = uri.replace('/', File.separatorChar);
if (uri.contains(File.separator + '.') || uri.contains('.' + File.separator) || uri.startsWith(".") || uri.endsWith(".") || INSECURE_URI.matcher(uri).matches()) {
return null;
}
return uri;
}
private static void sendError(ChannelHandlerContext ctx, HttpResponseStatus status) {
FullHttpResponse response = new DefaultFullHttpResponse(HttpVersion.HTTP_1_1, status, Unpooled.copiedBuffer("Failure: " + status.toString() + "\r\n", CharsetUtil.UTF_8));
response.headers().set(HttpHeaderNames.CONTENT_TYPE, "text/plain; charset=UTF-8");
ctx.writeAndFlush(response).addListener(ChannelFutureListener.CLOSE);
}
private static void setContentTypeHeader(HttpResponse response, File file) {
MimetypesFileTypeMap mimeTypesMap = new MimetypesFileTypeMap();
response.headers().set(HttpHeaderNames.CONTENT_TYPE, mimeTypesMap.getContentType(file.getPath()));
}
private static void setDateAndCacheHeaders(HttpResponse response, File fileToCache) {
SimpleDateFormat dateFormatter = new SimpleDateFormat(HTTP_DATE_FORMAT, Locale.US);
dateFormatter.setTimeZone(TimeZone.getTimeZone(HTTP_DATE_GMT_TIMEZONE));
Calendar time = new GregorianCalendar();
response.headers().set(HttpHeaderNames.DATE, dateFormatter.format(time.getTime()));
time.add(Calendar.SECOND, HTTP_CACHE_SECONDS);
response.headers().set(HttpHeaderNames.EXPIRES, dateFormatter.format(time.getTime()));
response.headers().set(HttpHeaderNames.CACHE_CONTROL, "private, max-age=" + HTTP_CACHE_SECONDS);
response.headers().set(HttpHeaderNames.LAST_MODIFIED, dateFormatter.format(new Date(fileToCache.lastModified())));
}
}
