Luasocket自定义标头，404转为301 [英] Luasocket custom headers, 404 turns to 301

问题描述

我之前的问题是使用 socket.http 模块在 lua 中获取页面标题。问题就在这里。以前，youtube网页引导我进入 404错误页面。根据 MattJ的帮助，我为自己设置了自定义主机标头请求。这就是我做的，结果是什么：

代码

  header = {host =youtube.com} 
本地结果，b，c，h = http.request {url =http://www.youtube.com/watch?v=_eT40eV7OiI，标题= header} 
 print（result，b，c，h）
表示k，v表示成对（c）打印（k，v）结束
  

结果

  1 301表：0047D430 HTTP / 1.1 301永久移动
 x-content-type-options nosniff 
 content-length 0 
 expires周二，1971年4月27日19:44:06 EST 
 cache-control no-cache 
连接关闭
位置http://www.youtube.com/watch?v=_eT40eV7OiI 
 content-type text / html; charset = utf-8 
 date星期六，2012年4月28日04:26:21 GMT 
 server wiseguy / 0.6.11 
  

据我所知，错误基本上是因为 X-Content-Type-Options 价值 nosniff 。阅读文档，我知道唯一定义的值，nosniff，阻止Internet Explorer从声明的内容类型中嗅探响应。

<请帮助我，以便我可以使用自定义代理并从他们的正文中获取youtube（和上一个问题中提到的其他一些网站）标题。这是我目前拥有的完整LUA文件：

  local http = requiresocket.http
 http.PROXY =http：//<代理地址在这里>：8080
 header = {host =youtube.com} 
本地结果，b，c，h = http.request {url = http://www.youtube.com/watch?v=_eT40eV7OiI，headers = header} 
 print（result，b，c，h）
表示k，v表示成对（c）打印（k，v）结束
  

解决方案

我相信这一行应该被更改：

  header = {host =youtube.com} 
  

收件人：

  header = {host =www .youtube.com} 
  

之后，对我有用。

My previous question was about fetching page title in lua using the socket.http module. The question lies here. Previously, youtube pages led me to a 404 error page. Based on MattJ's help, I put up custom HOST header for the request. This is what I did and what was the result:

Code

header = { host= "youtube.com" }
local result,b,c,h = http.request{ url = "http://www.youtube.com/watch?v=_eT40eV7OiI", headers = header }
print ( result, b, c, h )
for k,v in pairs(c) do print(k,v) end

Result

1   301 table: 0047D430 HTTP/1.1 301 Moved Permanently
x-content-type-options  nosniff
content-length  0
expires Tue, 27 Apr 1971 19:44:06 EST
cache-control   no-cache
connection  close
location    http://www.youtube.com/watch?v=_eT40eV7OiI
content-type    text/html; charset=utf-8
date    Sat, 28 Apr 2012 04:26:21 GMT
server  wiseguy/0.6.11

As far as I was able to understand from this, the error is basically because of X-Content-Type-Options valued nosniff. Reading its documentation, I got to know that the only defined value, "nosniff", prevents Internet Explorer from MIME-sniffing a response away from the declared content-type.

Please help me so that I can use custom proxy and fetch the youtube(and some other sites, as mentioned in the previous question) title from their body. Here is the complete LUA file I currently have:

local http = require "socket.http"
http.PROXY="http://<proxy address here>:8080"
header = { host= "youtube.com" }
local result,b,c,h = http.request{ url = "http://www.youtube.com/watch?v=_eT40eV7OiI", headers = header }
print ( result, b, c, h )
for k,v in pairs(c) do print(k,v) end

解决方案

I believe this line should be changed:

 header = { host= "youtube.com" }

To:

 header = { host= "www.youtube.com" }

After that, works for me.
