通过web运行Ruby脚本

I am following the Rails Tutorial by Michael Hart and I am already on Chapter 7. But I wanna do something different right now, which the tutorial doesn't teach. I wanna run a script file inside my webpage. How I can do that? I saw other posts here saying to use Sinatra, but since I am following this tutorial I don't think it is such a good idea to use it because it can make everything different from the tutorial.

我正在学习Michael Hart的Rails教程，我已经在第七章了。但是我现在想做一些不同的事情，这是本教程不教的。我想在我的网页中运行一个脚本文件。我怎么做呢?我在这里看到过其他文章说要使用Sinatra，但是由于我正在学习本教程，所以我不认为使用它是一个好主意，因为它可以使所有东西与本教程不同。

Here is the simple script I wanna run on my webpage:

这是我想在我的网页上运行的简单脚本:

#Somando idades

def soma_vetor_excluindo(index,vet)   
    soma = 0   
    for i in 0..9
        if(i!=index)
            soma = soma + vet[i].to_i
        end   
    end   
    return soma 
end

def soma_vetor(vet)   
    soma = 0   
    for i in 0..9
        soma = soma + vet[i].to_i   
    end   
    return soma 
end

def maior_vetor(vet)   
    maior = 0   
    for i in 0..9
        if(maior < vet[i])
            maior = vet[i]
        end   
    end   
    return maior 
end

idades = (0..9).collect{rand(99)+1}

soma_idades = (0..9).collect{0} soma = 0

print "#{idades} \n"

for i in 0..9   
    soma_idades[i] = soma_vetor_excluindo(i,idades) 
end

print "#{soma_idades} \n"

div = soma_vetor(soma_idades) / 9

resp = div - maior_vetor(soma_idades)

puts "#{resp}"

The simplest way to do it would be to make the method soma_vetor_excluindo, soma_vetor, maior_vetor, etc, controller methods, so when you send data through a form or ajax, the action would trigger, calculate the values and return you a result.

最简单的方法是使方法soma_vetor_exclusive indo、soma_vetor、maior_vetor等成为控制器方法，所以当您通过表单或ajax发送数据时，操作将触发、计算值并返回结果。

Knowing this, you can have a controller, let's say MathController.rb, and inside it, the soma_vetor_excluindo method:

知道这个，你可以有一个控制器，比如MathController。rb，以及其中的soma_vetor_exclusive indo方法:

class MathController < ApplicationController
  def soma_vetor_excluindo
  end
  def soma_vetor
  end
  def maior_vetor
  end
end

To access this, you probably need a route, so on your routes.rb add something like this:

要访问它，你可能需要一条路径，在你的路径上。rb添加如下内容:

get 'math/soma_vetor_excluindo/:index/:vet', to 'math#soma_vetor_excluindo'
get 'math/soma_vetor/:vet', to 'math#soma_vetor'
get 'math/maior_vetor/:vet', to 'math#maior_vetor'

This means that when your browser hit localhost/math/soma_vetor_excluindo/1/2 or the other urls, it would send a get request to the controller calling the soma_vetor_excluindo method and putting in the parameters, params[:index] and params[:vet], so theoretically the script would run.

这意味着当浏览器访问localhost/math/ soma_vetor_exclusive indo/1/2或其他url时，它将向调用soma_vetor_exclusive indo方法的控制器发送一个get请求，并输入参数params[:index]和params[:vet]，因此理论上脚本将运行。

The thing is, you can adapt your controller to do something like this with very little work.

问题是，你可以调整你的控制器去做这样的事情，只需要做很少的工作。

I believe the simplest solution is to load a page per script. First you add a path for your script into the routes.rb with something like:

我认为最简单的解决方案是每个脚本加载一个页面。首先，将脚本的路径添加到路由中。rb类似:

get 'scripts/your_script', to 'scripts#your_script

And in the controller (app/scripts_controller.rb) you should add your code like this:

在控制器(app/scripts_controller.rb)中，您应该添加如下代码:

class ScriptsController < ApplicationController
  #Somando idades

  def soma_vetor_excluindo(index,vet)   
    soma = 0   
    for i in 0..9
        if(i!=index)
            soma = soma + vet[i].to_i
        end   
    end   
    return soma 
  end

  def soma_vetor(vet)   
    soma = 0   
    for i in 0..9
        soma = soma + vet[i].to_i   
    end   
    return soma 
  end

  def maior_vetor(vet)   
    maior = 0   
    for i in 0..9
        if(maior < vet[i])
            maior = vet[i]
        end   
    end   
    return maior 
  end

  def your_script
    idades = (0..9).collect{rand(99)+1}
    soma_idades = (0..9).collect{0} 
    soma = 0

    answer = "#{idades} \n"
    for i in 0..9   
      soma_idades[i] = soma_vetor_excluindo(i,idades) 
    end

    answer << "#{soma_idades} \n"

    div = soma_vetor(soma_idades) / 9
    resp = div - maior_vetor(soma_idades)
    answer << "#{resp}"

    render(text: answer)
  end
end

when you access the page scripts/your_script, it should render a plain text presentation of your script result.

当您访问页面脚本/your_script时，它应该呈现您的脚本结果的纯文本表示。

Although this is not the most elegant solution, it should solve your problem.

虽然这不是最优雅的解决方案，但它应该能解决您的问题。
