Ruby：Net :: HTTP解析在結尾添加％0A

Question

我試圖打開一個名爲test.txt的文件，然後將每行導入一個名爲'line'的變量，然後將其添加到url文件中以發出請求。

require 'net/http' 
require 'uri' 

puts "Enter URL :-" 
gurl = gets.chomp 

total = File.foreach('test.txt').count 
c=0 

while(c < total) 
line = IO.readlines("test.txt")[c] 
aurl = "#{gurl}/#{line}" 
encoded_url = URI.encode(aurl) 
url = URI.parse(encoded_url) 
puts "\n #{url} \n" 
res = Net::HTTP.get_response(url) 
puts "\n Response received for #{line} => #{res.code} \n" 
c+=1 
end

http://www.example.com/z.php%0A 

Response received for z.php 
=> 404 

http://www.example.com/index.php%0A 

Response received for index.php 
=> 404 

反正逸出％0A（換行）？ 所有新紅寶石

Answer 1

如果test.txt有n行的，你看它的n + 1次！

下面是修改後的版本，它的Chomp刪除換行/換行字符：

require 'net/http' 
require 'uri' 

puts "Enter URL :-" 
gurl = gets.chomp 

File.foreach('test.txt') do |line| 
    line.chomp! 
    aurl = "#{gurl}/#{line}" 
    encoded_url = URI.encode(aurl) 
    url = URI.parse(encoded_url) 
    puts "\n #{url} \n" 
    res = Net::HTTP.get_response(url) 
    puts "\n Response received for #{line} => #{res.code} \n" 
end

您可以通過使用chomp只是刪除換行符：

line = IO.readlines("test.txt")[c].chomp
