是否有一种方法可以限制 Expressjs 中允许的 uri 字符。 例如设置字符变量 :
allowed_uri_chars = a-zA-Z0-9 ; etc

最合乎逻辑和最简单的方法就是 在某种中间软件中使用正方形:
var url = require("url");
app.use(function(req, res, next) {
var pathname = url.parse(req.url).pathname;
if(!pathname.match(/^[a-z0-9/]+$/i)) return res.send(403);
next();
});
或者,因为 URL 已经被 Express 解析了, 但是它并没有公开曝光, 您可能想要节省一个电话来分析并依靠 Express 内部( 我建议 ) :
app.use(function(req, res, next) {
if(!req._parsedUrl.pathname.match(/^[a-z0-9/]+$/i)) return res.send(403);
next();
});
这确保了您的路径名( http://example.com/foo/bar?id=1334
,路径名为 /foo/bar
)仅包含字母、数字和斜线。 如果不是,它会产生403。
您不能用正方块解析授权字符吗?
还是你的意思是直接在路线上?
