我在helloworld.asd
中定义了一个简单的系统:
(asdf:defsystem #:helloworld
:description "helloworld"
:author "Duncan Bayne <duncan@bayne.id.au>"
:license "WTFNMF"
:depends-on (#:hunchentoot)
:serial t
:components ((:file "package")
(:file "helloworld")))
... package.lisp
中的包定义:
(defpackage #:helloworld
(:use #:cl #:hunchentoot))
...以及helloworld.lisp
中对应的hello world网络服务器:
(in-package #:helloworld)
(defvar *acceptor* (make-instance 'acceptor :port 4242))
(start *acceptor*)
(define-easy-handler (greet :uri "/hello") ()
"<html><body><h1>Hello World!</h1></body></html>")
在SLIME REPL中,我使用以下命令启动Web服务器:
CL-USER> (load "/usr/home/duncan/code/helloworld/helloworld.asd")
CL-USER> (ql:quickload "helloworld")
如果我导航到http://localhost:4242/hello,我希望看到我的hello world HTML。相反,我收到404错误,日志显示:
127.0.0.1 - [2017-08-10 08:18:19] "GET /hello HTTP/1.1" 404 341 "-" "Mozilla/5.0 (X11; FreeBSD amd64; rv:54.0) Gecko/20100101 Firefox/54.0"
我怀疑我在这里遗漏了一些相当明显的东西;任何提示/指向文档将不胜感激。系统详细信息如下:
Clozure Common Lisp Version 1.11 (FreebsdX8664)
FreeBSD 11.1-RELEASE amd64
Hunchentoot 1.2.37
Mozilla Firefox 54.0.1

答案 0 :(得分:3)
您正在创建test$income <- cut(test$income,b=25)
levels <- c(-0.853,-0.586,-0.325,-0.0643,0.196,0.457,0.718,0.978,1.24,1.5,1.76,2.02,2.28,2.54,2.8,3.06,3.32,3.59,3.85,4.11,4.37,4.63,4.89,5.15,5.41,5.68)
train$income <- cut(train$income,levels)
而不是ACCEPTOR
(或子类)的实例。易处理程序已注册,但您的接受者不会使用它。这应该有用,例如:
EASY-ACCEPTOR
