Grails URL映射和URL中的斜杠字符 [英] Grails URL Mapping and slash character in URL

问题描述

我的Grails（2.2.0）应用程序具有以下URL映射：

 / api / clientQuote / $ labcode / $ cliCode / $ quoCode（controller：clientQuote）{
 action = [GET：get] 
} 
  

假设以下值：

  $ labcode = BRMIN 
 $ cliCode = CL-000236 
 $ quoCode = QT-000965 / 0-0 
  

由于$ quoCode具有斜杠字符，因此需要将其替换为％2F。这样，一个可能的网址可能是：

http://myapp.com:9090/CCLASService/api/clientQuote/BRMIN/CL-000236/QT-000965%2F0-0

当我在任何浏览器中放置此URL时，会显示一个空白屏幕作为返回。这很奇怪，因为请求甚至不能到达我的Grails控制器。

另一方面，如果我更改以下网址：

http://myapp.com:9090/CCLASService/clientQuote/get?labcode=BRMIN&cliCode=CL-000236&quoCode=QT-000965%2F1-0

一切工作正常，我收到了正确的XML响应我的请求。

问题是：为什么当我使用特定的URL映射与编码字符我收到一个空白屏幕作为回报？

解决方案

URL映射可以使用 $ paramName ** 一个特定的参数 - 这通常用于类似于CMS的地方，您希望将整个虚拟路径层次结构映射到单个控制器，但它也可能对您的情况有用。

 / api / clientQuote / $ labcode / $ cliCode / $ quoCode **（controller：clientQuote）{
 action = [GET：get] 
} 
  

这将允许 http://myapp.com ：9090 / CCLASService / api / clientQuote / BRMIN / CL-000236 / QT-000965 / 0-0 即使没有斜线逃脱。

I'm facing the following problem:

My Grails (2.2.0) app has the following URL Mapping:

"/api/clientQuote/$labcode/$cliCode/$quoCode"(controller: "clientQuote") {
  action = [GET: "get"]
}

Let's suppose the following values:

$labcode = BRMIN
$cliCode = CL-000236
$quoCode = QT-000965/0-0

Since $quoCode has a slash character, it's necessary to replace it for %2F. This way, a possible URL could be:

http://myapp.com:9090/CCLASService/api/clientQuote/BRMIN/CL-000236/QT-000965%2F0-0

When I put this URL in any browser a blank screen is showed as return. It's strange because the request doesn't even reach my Grails controller.

For other side, if I change the url for:

http://myapp.com:9090/CCLASService/clientQuote/get?labcode=BRMIN&cliCode=CL-000236&quoCode=QT-000965%2F1-0

Everything works fine, I receive a correct XML response to my request.

The question is: Why when I use a specific URL Mapping with a encoded character I receive a blank screen as return?

解决方案

URL mappings can use $paramName** to allow slashes within a particular parameter - this is typically used with something like a CMS where you want to map a whole virtual path hierarchy to a single controller, but it could be useful in your case too.

"/api/clientQuote/$labcode/$cliCode/$quoCode**"(controller: "clientQuote") {
  action = [GET: "get"]
}

This would permit http://myapp.com:9090/CCLASService/api/clientQuote/BRMIN/CL-000236/QT-000965/0-0 even without the slash escaped.
