在Twirl模板中将Scala JsValue转换为JavaScript对象

我的问题非常简单。我有一个

play.api.libs.json.JsValue

Scala对象，它是通过Linkedin的RESTAPI获得的

看起来是这样的：

我的Twirl模板中提供了

linkedinProfile:play.api.libs.json.JsValue

对象

但我无法将其作为JavaScript对象传递给JavaScript控制器。我试着这样做：

直接在模板中调用控制器会破坏模式

在控制器中，您通常会执行以下操作

class FooController() extends Controller {

  def index() = Action { 
    //fetch from linkedin or where ever    
    val result: JsValue = Json.obj("foo" -> "bar")
    Ok(views.html.index(result))
  }

}

视图：

@import play.api.libs.json.JsValue
@(result: JsValue)

<script type="text/javascript">
    document.addEventListener("DOMContentLoaded", function() {
       @result
    });
</script>

@import play.api.libs.json.JsValue
@（结果：JsValue）
document.addEventListener（“DOMContentLoaded”，function（））{
@结果
});

@Html（linkedinProfile.toString）

应该直接生成以下内容：

{"apiStandardProfileRequest":{"headers":{"_total":1,"values":[{"name":"x-li-auth-token","value":"name:ry53"}]},"url":"https://api.linkedin.com/v1/people/1WO4xzvPJ1"},"currentShare":{"author":{"firstName":"Christophe","id":"1WO4xzvPJ1","lastName":"Bram"},"comment":"Cruited is searching for a second web developer!","content":{"description":"Cruited is a self-financed startup.

它没有这样做的原因是，我的

JsValue

是一个

JsString

，而它应该是一个

JsObject

为什么你问的是

JsString

？因为它是以

Json.toJson（jsonString）

（糟糕！）的形式诞生的，而不是

Json.parse（jsonString）

（好！）
