我正在运行一个似乎忽略编码的 netty 服务器。d3.js 中的错误是由于 PI 符号引起的。下面是设置编码的代码。即使在硬编码之后它仍然不起作用,任何想法为什么?
RandomAccessFile raf;
try {
raf = new RandomAccessFile(file, "r");
} catch (FileNotFoundException fnfe) {
sendError(ctx, NOT_FOUND);
return;
}
long fileLength = raf.length();
HttpResponse response = new DefaultHttpResponse(HTTP_1_1, OK);
setContentTypeHeader(response, file);
setContentLength(response, fileLength);
setDateAndCacheHeaders(response, file);
if (isKeepAlive(request)) {
response.setHeader(CONNECTION, HttpHeaders.Values.KEEP_ALIVE);
}
// Write the initial line and the header.
ctx.write(response);
// Write the content.
ChunkedFile chunkedFile = new ChunkedFile(raf, 0, fileLength, 8192);
ChannelFuture writeFuture = ctx.write(chunkedFile);
ctx.write(chunkedFile, writeFuture);
这是setContentTypeHeader
代码:
private static void setContentTypeHeader(HttpResponse response, File file) {
String contentType = MimeTypes.getContentType(file.getPath());
response.setHeader(CONTENT_TYPE, contentType);
if (!contentType.equals("application/octet-stream")) {
response.setHeader(CONTENT_ENCODING, "charset=utf-8");
}
}
