文件阅读来自亚马逊的服务器，Ruby on Rails的，没有匹配的路由 [英] File reading from Amazon server, ruby on rails, no match route

问题描述

我现在开发上轨，Heroku的服务器和AWS应用红宝石。 在应用方面，我要读的文本文件。我测试在本地，现在把这个文件在AWS。

当我把我的AWS文件的地址，下面的错误信息弹出。

 变量Errno :: ENOENT（没有这样的文件或目录@ rb_sysopen  -  https://s3-us-west-2.amazonaws.com/ringleplus2015/my_file.txt）：
 

当我复制粘贴此地址在Chrome浏览器，我可以下载的文件没有问题。

  #FILE = File.open方法（./ my_file.txt适用，R）
文件= File.open方法（https://s3-us-west-2.amazonaws.com/testbuckethoho/my_file.txt，R）
 

我允许任何人阅读。

此外，在html.rb文件，我也把链接，用户将能够从PDF文件下载。 目标=_空白级=BTN BTN-LG BTN-默认>案例下载

但是，当我点击它，它说：此网页无法使用。我期待地址仔细和：走了的HTTPS和//

<$p$p><$c$c>https//s3-us-west-2.amazonaws.com/testbuckethoho/What+Consumers+Want+from+Their+Displays+%7C+The+Applied+Materials+Blog.pdf

当我有：在那里，它的工作原理。但是，如果我有：在我的HTML文件，它使我这个错误

 没有路由匹配[GET] "/home/:/https:/s3-us-west-2.amazonaws.com/testbuckethoho/What+Consumers+Want+from+Their+Displays+%7C+The+Applied+Materials+Blog.pdf"
 

会有人帮我找出现在是什么原因造成这个问题和处理呢？ ：）

解决方案

红宝石寻找一个名为本地文件 https://s3-us-west-2.amazonaws.com/testbuckethoho/my_file .TXT 。它不知道做一个请求到远程主机。

有一个不同的方法来解决这个问题，内置的一个是开放式URI 。

I'm now developing Ruby on rails application with Heroku server and AWS. In the application, I have to read the text file. I tested locally and now put this file in AWS.

When I put the address of my file in AWS, the below error message pops up.

Errno::ENOENT (No such file or directory @ rb_sysopen - https://s3-us-west-2.amazonaws.com/ringleplus2015/my_file.txt):

When I copy and paste this address at Chrome, I can download file without an issue.

#file = File.open("./my_file.txt","r")  
file = File.open("https://s3-us-west-2.amazonaws.com/testbuckethoho/my_file.txt","r")

I allowed anybody to read this.

Also, in the html.rb file, I also put the link that users would be able to download pdf file from. " target="_blank" class="btn btn-lg btn-default">Case Download

But when I clicked it, it says " This webpage is not available." I look the address carefully and the ":" is gone between "https" and "//"

https//s3-us-west-2.amazonaws.com/testbuckethoho/What+Consumers+Want+from+Their+Displays+%7C+The+Applied+Materials+Blog.pdf

When I include ":" there, it works. But if I include ":" in my html file, it leads me to this error.

No route matches [GET] "/home/:/https:/s3-us-west-2.amazonaws.com/testbuckethoho/What+Consumers+Want+from+Their+Displays+%7C+The+Applied+Materials+Blog.pdf"

Would anybody help me figure out what is now causing this problem and handle it? :)

解决方案

Ruby is looking for a local file named https://s3-us-west-2.amazonaws.com/testbuckethoho/my_file.txt. It doesn't know to make a request to a remote host.

There's a various approaches to solve this, the built-in one is open-uri.
