Question

如何使用Play 2在模板中对URL进行编码？

我搜索一个这样的帮手：

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

我找到了pull request，但这似乎不适用于实际播放的2.0.3版本。

Answer 1

从2.1开始，您可以使用@helper.urlEncode

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

Answer 2

正如我在linked ticked中看到的那样，它将在Play 2.1中得到解决

最快的解决方案是在您的控制器（此示例中为Application.java）放置，方法

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());
}

然后根据需要在视图中使用它：

<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/>

Answer 3

使用@ helper.urlEncode，如

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

返回

而我需要/预期的是

http://www.giulio.ro/image/magictoolbox_cache/3bf842518f40ca6b8a10b619b8e02daf/6/2/621/thumb320x320/0804-427%20-%20255%20lei.jpg
