如何使用ruby下载多个动态文件？(How do I download multiple dynamic files using ruby? [closed])

python 
 我想从网站下载带有ruby的多个动态文件。 有五个不同的文件，它们都有一个基本结构： 
 

 backup_YYYY - MM - DD - HHMM _JRAddOns_Die_Pflegeserie_fr_ ID - CONTENT 。 结尾 
 

 所有大胆的书面部分都是动态的，必须更换。 
 

 文件可能如下所示： 
 

backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-plugins.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-themes.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-uploads.zip

 

 有人可以帮忙吗？ 
 

 编辑：我尝试了一个不会长时间工作的非动态版本，但是： 
 

puts 'Starting Download...'
require 'net/http'
Net::HTTP.start("jr-addons.de") do |http|
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz", "wb") do |file|
        file.write(resp.body)
    end
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip", "wb") do |file|

I want to download multiple dynamic files with ruby from a website. There are five different files and they all have a basic structure:
 

backup_YYYY-MM-DD-HHMM_JRAddOns_Die_Pflegeserie_fr_ID-CONTENT.ENDING
 

All the bold written parts are dynamic and have to be replaced.
 

The files could look like this:
 

backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-plugins.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-themes.zip
backup_2017-03-06-1020_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-uploads.zip

 

Could someone help?
 

Edit: I tried a non-dynamic version of it which wont work long, though: 
 

puts 'Starting Download...'
require 'net/http'
Net::HTTP.start("jr-addons.de") do |http|
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-db.gz", "wb") do |file|
        file.write(resp.body)
    end
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-others.zip", "wb") do |file|
        file.write(resp.body)
    end
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-plugins.zip")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-plugins.zip", "wb") do |file|
        file.write(resp.body) 
    end
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-themes.zip")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-themes.zip", "wb") do |file|
        file.write(resp.body) 
    end
    resp = http.get("/btemp/backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-uploads.zip")
    open("backup_2016-10-23-1520_JRAddOns_Die_Pflegeserie_fr_2867ed5aba3d-uploads.zip", "wb") do |file|
        file.write(resp.body)
    end
end

最满意答案

 解决方案取决于您拥有的编辑器，编辑器可能找到的环境变量以及编辑器是否采用任何命令行参数。 
 

 这是一个简单的解决方案，适用于Windows，没有任何环境变量或编辑器的命令行参数。 根据需要进行修改。 
 

import subprocess
import os.path

def start_editor(editor,file_name):

    if not os.path.isfile(file_name): # If file doesn't exist, create it
        with open(file_name,'w'): 
            pass

    command_line=editor+' '+file_name # Add any desired command line args
    p = subprocess.Popen(command_line)
    p.wait()

file_name='test.txt' # Probably known from elsewhere
editor='notepad.exe' # Read from environment variable if desired

start_editor(editor,file_name)

with open(file_name,'r') as f: # Do something with the file, just an example here
    for line in f:
        print line


The solution will depend on what editor you have, which environment variable the editor might possibly be found in and if the editor takes any command line parameters.
 

This is a simple solution that works on windows without any environment variables or command line arguments to the editor. Modify as is needed.
 

import subprocess
import os.path

def start_editor(editor,file_name):

    if not os.path.isfile(file_name): # If file doesn't exist, create it
        with open(file_name,'w'): 
            pass

    command_line=editor+' '+file_name # Add any desired command line args
    p = subprocess.Popen(command_line)
    p.wait()

file_name='test.txt' # Probably known from elsewhere
editor='notepad.exe' # Read from environment variable if desired

start_editor(editor,file_name)

with open(file_name,'r') as f: # Do something with the file, just an example here
    for line in f:
        print line
