今天在用hexo写博文时遇到一个涉及中文的302问题,记录一下。

当访问链接为http://middle3.dev.vivo.xyz:4000/authors/测试时,控制台报错:

代码语言:javascript复制
TypeError: The header content contains invalid characters
   at ServerResponse.OutgoingMessage.setHeader (_http_outgoing.js:358:11)

   at HTTPParser.parserOnIncoming [as onIncoming] (_http_server.js:546:12)
   at HTTPParser.parserOnHeadersComplete (_http_common.js:99:23)

跟踪了下hexo-server/lib/middlewares/route.js的代码如下:

代码语言:javascript复制
var url = route.format(decodeURIComponent(req.url));
var data = route.get(url);
var extname = pathFn.extname(url);

// When the URL is `foo/index.html` but users access `foo`, redirect to `foo/`.
if (!data) {
  if (extname) return next();

  res.statusCode = 302;
  res.setHeader('Location', root   url   '/');
  res.end('Redirecting');
  return;
}

这里url是decode出来的字符串,如果字符串里包含中文,然后调用res.setHeader方法即会报上面的错,解决方法也比较简单,加入一行即可:

代码语言:javascript复制
if (!data) {
  if (extname) return next();

  url = encodeURI(url);

  res.statusCode = 302;
  res.setHeader('Location', root   url   '/');
  res.end('Redirecting');
  return;
}

进一步查了下,hexo-server的git版本是修复了这个问题的,见这里,但hexo依赖的hexo-server@0.2.0版本却没有修复这个问题,估计很多非英语用户都会遇到这个问题,真坑爹!
