在Rails中服务PHP(Service PHP in Rails)

我有一个小的PHP服务，由AJAX在JavaScript文件中调用：

$.ajax({ type: "GET", url: "getDate.php", dataType:"json", data :{ fromDate:fromDate, toDate:toDate }, success: function(data) { ...... } });

该服务包含：

$fromDate = $_GET['fromDate']; $toDate = $_GET['toDate']; $fromDate=date_create($fromDate); $fromdate = date_format($fromDate,"Y-m-d")."T".date_format($fromDate,"H:i:s")."Z"; $fromdate = urlencode($fromdate); $toDate=date_create($toDate); $todate = date_format($toDate,"Y-m-d")."T23:00:00Z"; $todate = urlencode($todate); $url = "http://194.209.53.19:8086/query?db=Bellevue&q=select+*+from+measures+where+time%3E%3D%27".$fromdate."%27+and+time%3C%3D%27".$todate."%27"; $data = file_get_contents($url, false); echo $data;

我需要在我的Rails应用程序中使用它。我想知道我是否可以将.php文件放在Rails文件夹中，然后简单地调用它。或者，如果有办法在Rails中执行类似的服务？

I have a small PHP service that is being called in a JavaScript file by AJAX :

$.ajax({ type: "GET", url: "getDate.php", dataType:"json", data :{ fromDate:fromDate, toDate:toDate }, success: function(data) { ...... } });

$fromDate = $_GET['fromDate']; $toDate = $_GET['toDate']; $fromDate=date_create($fromDate); $fromdate = date_format($fromDate,"Y-m-d")."T".date_format($fromDate,"H:i:s")."Z"; $fromdate = urlencode($fromdate); $toDate=date_create($toDate); $todate = date_format($toDate,"Y-m-d")."T23:00:00Z"; $todate = urlencode($todate); $url = "http://194.209.53.19:8086/query?db=Bellevue&q=select+*+from+measures+where+time%3E%3D%27".$fromdate."%27+and+time%3C%3D%27".$todate."%27"; $data = file_get_contents($url, false); echo $data;

I need to use this in my Rails application. I was wondering if I could put the .php file in a Rails folder, and simply call it. Or if there's a way to do a similar service in Rails?

最满意答案

当然，你可以在Rails中做到这一点。首先，您需要为您的请求定义路线。在routes.rb文件中写下以下内容，位于config / routes.rb：

get "/getDate" => "generals#get_date"

这意味着：每当有/getDate的GET请求时，转到控制器GeneralController ，并调用其名为get_date函数。如果你写了users#get_date ，Rails会尝试在UsersController找到get_date方法。

通过以下命令生成您选择的控制器：

rails generate controller General

它将在app / controller和其他文件中生成一个名为general_controller.rb的文件。

现在，您需要在那里定义所有逻辑。其他的事情：在PHP中，您使用$_GET['formDate']获取发送的数据，但在Rails中，您将通过执行params[:formDate]来完成相同的功能。

def get_date form_date = params[:formDate] # and now here you can write all your logic, and can finally return the response respond_to do |format| format.json { render json: data_to_be_returned } end end

编辑：

对于PHP中的date_create或date_format函数，您可以在此处和此处查找它们的等价物。

Sure, you can do this in Rails. First, you need to define the route for your request. Write the following in your routes.rb file, located at config/routes.rb:

get "/getDate" => "generals#get_date"

What that means is: whenever there is a GET request for /getDate, go to controller GeneralController, and invoke its function named get_date. If you wrote users#get_date, Rails would try to find the get_date method in UsersController.

Generate the controller of your choice by following command:

rails generate controller General

It will generate a file named general_controller.rb in app/controller among other files.

Now, you need to define all your logic there. Other thing: in PHP, you get the sent data using $_GET['formDate'], but in Rails, you will accomplish the same functionality by doing params[:formDate].

def get_date form_date = params[:formDate] # and now here you can write all your logic, and can finally return the response respond_to do |format| format.json { render json: data_to_be_returned } end end

Edit:

For date_create or date_format functions in PHP, you can look up their equivalents at here and here.
