Scala 和 Play 应用的 Stripe 支付库问题

Question

我已经创建了 Scala 和 Play Framework 应用程序，我正在尝试使用它来使用 Stripe 支付库。但是当我使用时出现以下错误：

Compilation error

object stripe is not a member of package com

我使用的版本如下，

Scala 版本：2.11.6
SBT 版本：0.13.8

我在 build.sbt 中使用了 Stripe SBT 依赖项，如下所示，

"com.stripe"    % "stripe-scala_2.9.1"      % "1.1.2"

我的 build.sbt 文件如下：

name := """My App Name"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
  cache,
  ws,
  filters,
  "com.typesafe.play"                         %% "play-mailer"            % "3.0.1",
  "com.typesafe.play"                         %% "play-slick"             % "1.1.1",
  "com.typesafe.play"                         %% "play-slick-evolutions"  % "1.1.1",
  "postgresql"                                %  "postgresql"             % "9.1-901.jdbc4",
  "commons-lang"                              % "commons-lang"            % "2.6",
  "com.stripe"                                % "stripe-scala_2.9.1"      % "1.1.2"
)

// Play provides two styles of routers, one expects its actions to be injected, the
// other, legacy style, accesses its actions statically.
routesGenerator := InjectedRoutesGenerator

我的控制器出现异常：

package controllers

import com.stripe
import com.stripe.{Charge, Customer}
import play.api.mvc._
/**

class PaymentController extends Controller {

  def getPayment = Action { request =>
    val formData = (request.body).asFormUrlEncoded

    val stripe.apiKey = "sk_test_xxxxxxxxxxxxx";
    val token = formData.get("stripeToken")(0)

    val customerParams = Map("source" -> token, "description" -> "Customer Rollback Renew req.")

    val customer = Customer.create(customerParams)

    val chargeParams = Map("amount" -> 2000, "currency" -> "usd", "customer" -> customer.id)

    Charge.create(chargeParams);

    Ok
  }

}

一切看起来都不错，但不知道为什么我会遇到这个编译问题。

嗯，根据错误消息，您遇到了不兼容的 Scala 版本问题。基本上@cchantep 在评论中告诉你的。请记住，Scala 2.9.x 与 Scala 2.11.x 二进制不兼容，您只是在混合两个版本时提出问题。

删除 build.sbt 文件的以下行：

"com.stripe" % "stripe-scala_2.9.1" % "1.1.2"

并添加Stripe提供的更新和维护的客户端版本：

"com.stripe" % "stripe-java" % "2.4.0"

之后，您需要重写代码才能使用这个新客户端。这是一个基于 Stripe docs 以及您的代码的示例：

def getPayment = Action { request =>
  val requestOptions = new RequestOptionsBuilder()
    .setApiKey("sk_test_xxxxxxxxxxxxx")
    .build()

  val formData = (request.body).asFormUrlEncoded
  val token = formData.get("stripeToken")(0)
  val customerParams = Map("source" -> token, "description" -> "Customer Rollback Renew req.")

  val customer = Customer.create(customerParams)

  val chargeParams = Map("amount" -> 2000, "currency" -> "usd", "customer" -> customer.id)

  Charge.create(chargeParams, requestOptions);

  Ok
}

但是...请记住，这段代码只是一个起点，它有问题（每个实例都是阻塞的）。
