如何使用Ruby在文本文件中搜索完全匹配的字符串? [英] How to search for exact matching string in a text file using Ruby?
问题描述
我生成了一个文本文件,该文件具有带有响应主体的HTTP请求响应标头.
我想在此文件中搜索以包含Access-Control-Allow-Origin: *
作为标题的响应标题.
I generated a text file having HTTP Request Response headers with response body.
I want to search inside this file looking for response headers containing Access-Control-Allow-Origin: *
as a header.
该文件包含以->
开头并以"
结束的行的形式,如下所示:
The file contains this in the form of a line starting with ->
and ending with "
like this:
-> "Access-Control-Allow-Origin: *\r\n"
如何使用if
条件搜索此文本文件并在请求响应标题上方打印自定义消息?
How can I search this text file and print a custom message above the request response headers using an if
condition?
我需要一些复杂的正则表达式吗?
Do I need some complex regex?
使用我的代码,我无法获得正确的搜索:
With my code I can not get the correct search:
require 'net/http'
require 'uri'
require 'IPAddr'
require 'timeout'
puts "Origin IP:\n\n"
originip = gets()
puts "Start IP:\n\n"
startip = gets()
puts "End IP:\n\n"
endip = gets()
(IPAddr.new("#{startip}")..IPAddr.new("#{endip}")).each do |address|
begin
uri = URI("http://#{address.to_s}")
http = Net::HTTP.new(uri.host, uri.port)
http.set_debug_output($stdout)
request = Net::HTTP::Get.new(uri.request_uri)
request.initialize_http_header({"Origin" => "#{originip}"})
response = http.request request
$stdout.reopen('Access-Control-Allow-Origin.txt','a')
f = File.Open('Access-Control-Allow-Origin.txt')
line = f.read
if line = /Access-Control-Allow-Origin: */ then
puts "\n\nAccess-Control-Allow-Origin: * Header Found:\n\n"
else
puts "\n\nAccess-Control-Allow-Origin: * Header Not Found:\n\n"
end
rescue Timeout::Error => exc
puts "ERROR: #{exc.message}"
rescue Errno::ETIMEDOUT => exc
puts "ERROR: #{exc.message}"
rescue Exception => exc
puts "ERROR: #{exc.message}"
end
end
推荐答案
您的if语句使用了错误的运算符.
Your if statement is using the wrong operator.
if line =~ /Access-Control-Allow-Origin: */
