Lua:获取网页 [英] Lua : Fetch a webpage

问题描述

我想获取网页并以字符串形式获取结果，但我不知道该怎么做.我在网上搜索并没有找到如何操作.

I want to fetch a webpage and get the result in a string, but I don't know how to do it. I search online and didn't find how to do it.

推荐答案

我会简单地使用 Lua Socket 附带一个 http 子模块.您可以简单地使用 http.request 将网页放入您想要的任何容器中(默认为字符串，但您可以使用表、文件、stdio，...使用 ltn12 过滤器和接收器).

I'd simply use Lua Socket which comes with an http submodule. You can simply use http.request to get a webpage into whatever container you'd want (default is string, but you can use a table, a file, stdio, ... using ltn12 filters and sinks).

举个例子:

local http=require'socket.http'
local body, statusCode, headers, statusText = http.request('http://w3.impa.br/~diego/software/luasocket/http.html')
print('statusCode ', statusCode)
print('statusText ', statusText)
print('headers ')
for index,value in pairs(headers) do
    print("	",index, value)
end
print('body',body)
