Encode an URL with Play 2

问题:

How can I encode an URL in a template with Play 2?

I search a helper like this:

<a href="@urlEncode(name)">urlEncode doesn't work now</a>

I have found a pull request, but this doesn't seem to work with the actual play 2.0.3 release.

回答1:

As of 2.1 you can use @helper.urlEncode

<a href="@helper.urlEncode(foo)">my href is urlencoded</a>

回答2:

As I can see in linked ticked it will be resolved in Play 2.1

Quickest solution is placing ,method(s) for that in you controller (Application.java in this sample)

public static String EncodeURL(String url) throws java.io.UnsupportedEncodingException {
    url = java.net.URLEncoder.encode(url, "UTF-8");
    return url;
}

public static String EncodeURL(Call call) throws java.io.UnsupportedEncodingException {
    return EncodeURL(call.toString());
}

and then using it in the view as required at the moment:

<a href='@Application.EncodeURL(routes.Application.someAction())'>
    Encoded url form router</a>  <br/>

<a href='@Application.EncodeURL("/this/is/url/to/encode")'>
     Encoded url from string</a>  <br/>

<a href='@routes.Application.someAction()?encoded=@Application.EncodeURL(routes.Application.someOtherAction())'>
     Url mixed normal+encoded</a>  <br/>

Using @helper.urlEncode as in

@helper.urlEncode("http://www.giulio.ro/image/magictoolbox_cache/3bf842518f40ca6b8a10b619b8e02daf/6/2/621/thumb320x320/0804-427 - 255 lei.jpg")

returned

while what I needed/expected was
