我輸入驗證碼原始http請求:爲什麼我會收到400錯誤請求錯誤?

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

輸出的第一行是400錯誤的請求

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

我相信主機頭可能沒有結尾斜槓。

西蒙是對的,我想。

這你想要做什麼,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 

這或許是另一種方式:

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