Question

I'm trying to learn web programming in Racket. The question is this: when I'm clicking <a> link my localhost writes that "file in not found", although the link is all right. When in turn I run file that link points to in Dr. Racket localhost is ok. Why is that? Also how do I redirect in Racket?

您可以通过serve/servlet的#:extra-files-paths选项为网络服务器提供的文件提供额外路径。

以下是基于您在评论中提供的内容的示例：

#lang web-server

(require web-server/servlet-env)

(define (start req)
  (response/xexpr
   `(html (head (title"")) (body (a ((href "/hello.rkt"))"go")))))

;; assuming the module is in /tmp and run from there
(serve/servlet start #:servlet-path "/query.rkt"
               ;; whatever extra file paths you need
               ;; in this example hello.rkt is in /tmp
               #:extra-files-paths (list "/tmp"))

Racket localhost无法从<a href="">
