原始http请求：为什么我会收到400错误请求错误？

Question

我输入验证码

p: open tcp://rebol.com:80 
insert p "HEAD/HTTP/1.1 ^/" 
insert p "Host: rebol.com/ ^/^/" 
while [data: copy p][prin data] 

输出的第一行是400错误的请求

>> p: open tcp://rebol.com:80 
>> insert p "HEAD/HTTP/1.1 ^/" 
>> insert p "Host: rebol.com/ ^/^/" 
>> while [data: copy p][prin data]

为什么我得到400错误的请求？

Answer 1

我相信主机头可能没有结尾斜杠。

Answer 2

西蒙是对的，我想。

这你想要做什么，我想：

p: open tcp://rebol.com:80 
insert p "HEAD/HTTP/1.1 ^/" 
insert p "Host: rebol.com^/^/" 
while [data: first p][prin data] 

    HTTP/1.1 200 OK 
    Date: Sun, 18 Jul 2010 12:28:19 GMT 
    Server: Apache/1.3.42 (Unix) [.....] 
    Last-Modified: Thu, 15 Jul 2010 18:59:21 GMT 
    ETag: "3d0121-1c2a-4c3f5a89" 
    Accept-Ranges: bytes 
    Content-Length: 7210 
    Content-Type: text/html 

这或许是另一种方式：

p: open http://rebol.com 
probe p/locals/headers 
make object! [
