Question

我正在尝试使用Webjars在Play Scala模板中实现PayPal结帐按钮。这是sbt中的定义：

   "org.webjars" %% "webjars-play"% "2.6.1",
   "org.webjars"% "bootstrap"% "4.2.1" exclude ("org.webjars", "jquery"),
   "org.webjars"% "jquery"% "3.2.1",

这是模板中的导入：

@import org.webjars.play.WebJarsUtil

我还包括jQuery，Popper.js和bootstrap javaScript插件脚本。

以下html在浏览器中运行良好：

<!DOCTYPE html>
<html>
<!DOCTYPE html>
<head>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <meta http-equiv="X-UA-Compatible" content="IE=edge" />
  <script
   src="https://www.paypal.com/sdk/js?client-id=sb">
  </script>
</head>
<body>
  <div id="paypal-button-container"></div>
  <script>
    paypal.Buttons().render('#paypal-button-container');
  </script>
</body>
</html>

，但不会在播放模板中呈现感谢您为解决此问题提供的帮助

Krzysztof，通过对Play配置进行以下修改解决了问题：

# Security Filter Configuration - Content Security Policy
play.filters.headers {
  contentSecurityPolicy = "default-src 'self' * .paypal.com;"
  contentSecurityPolicy = $ {play.filters.headers.contentSecurityPolicy} "img-src 'self' data: * .fbcdn.net * .twimg.com * .googleusercontent.com * .xingassets.com vk.com * .yimg.com secure .gravatar.com; "
  contentSecurityPolicy = $ {play.filters.headers.contentSecurityPolicy} "style-src 'self' 'unsafe-inline' cdnjs.cloudflare.com maxcdn.bootstrapcdn.com cdn.jsdelivr.net fonts.googleapis.com;"
  contentSecurityPolicy = $ {play.filters.headers.contentSecurityPolicy} "font-src 'self' fonts.gstatic.com fonts.googleapis.com cdnjs.cloudflare.com;"
  contentSecurityPolicy = $ {play.filters.headers.contentSecurityPolicy} "script-src 'self' 'unsafe-inline' 'unsafe-eval' cdnjs.cloudflare.com * .paypal.com;"
  contentSecurityPolicy = $ {play.filters.headers.contentSecurityPolicy} "connect-src 'self' twitter.com * .xing.com * .paypal.com;"

谢谢¡

我还想从Play 2.6.11迁移到Play 2.7.0。但是，在包含了插件和Requirejs的依赖关系之后，我在执行过程中遇到以下错误：

ProvisionException: Unable to provision, see the following errors: 1) Error injecting constructor, java.lang.AbstractMethodError: Method org / webjars / play / RequireJS.play $ api $ mvc $ Results $ _setter_ $ PreconditionRequired_ $ eq (Lplay / api / mvc / Results $ Status;) V is abstract at org.webjars.play.RequireJS. <init> (RequireJS.scala: 9) at org.webjars.play.RequireJS.class (RequireJS.scala: 9) while locating org. webjars.play.RequireJS for the 2nd parameter of webjars.Routes. <init> (Routes.scala: .........

我想知道可能会有什么困难非常感谢

您的问题是由Play应用中的CspFilter引起的。如果您使用的是2.7或更高版本，则可以将csp nonce添加到要添加到页面的每个脚本中。假设这是您的模板：

@* At the beggining import CSPNonce *@
@import views.html.helper.CSPNonce

@* It's important that you pass implicit request to your view, without script won't compile *@
@(title: String)(content: Html)(implicit request: RequestHeader)

<!DOCTYPE html>
<html lang="en">
    <head>
        @* Adding  @{CSPNonce.attr} would generate nonce for external script *@
        <script @{CSPNonce.attr} src="https://www.paypal.com/sdk/js?client-id=sb"></script>
    </head>
    <body>
      <div id="paypal-button-container"></div>
        @* Adding  @{CSPNonce.attr} would generate nonce for inline script *@
      <script @{CSPNonce.attr}>
        paypal.Buttons().render('#paypal-button-container');
      </script>
    </body>
</html>

在2.6版中以及未实现随机数之前，因此您必须自己实现它，或者允许在评估内联脚本时不使用随机数。

play.filters.headers.contentSecurityPolicy = "default-src 'self'; script-src 'self' 'unsafe-inline' https://www.paypal.com"
