How to pass raw html to Play framework view?

问题

I'm trying to pass a simple URL to a view within a play framework app, however when passed as a string, the & in the url is changed to & which causes the URL to not work.

If I change the argument to Html, i.e @(url: Srting) to @(url: Html), then I get an error when I try to pass the url as string to view.render() method.

How can I convert the url into Html and pass it as that?

回答1:

To prevent the default escaping that happens for dynamic content on views you need to wrap the String with @Html(String) function:

View:

@(url: String)
<div class="myLink">
   Go to: @Html(url) <br>
   not to: @url
</div>

Controller:

public static Result displayLink(){
   return ok(view.render("<a href='http://stackoverflow.com/'>Stack Overflow</a>"));
}

See The template engine page on the documentation for more info (specifically the "Escaping" section at the very bottom).

If you want to render HTML content instead of displaying it as raw text, return the content .as("text/html"). Example:

WS.url("http://www.stackoverflow.com").get().map(resp => Ok(resp.body).as("text/html"))
