Scalamock：如何指定元组的任意序列

Question

我正在尝试像这样为Play的WSClient创建模拟：

  def mockGet[A](url : String, method : String, headers : Seq[(String, String)], timeout : Duration)(
    response: Future[AhcWSResponse]
  ) =
    (mockWsClient
      .url(_ : String)
        .withMethod(_ : String)
        .withHttpHeaders(_: (String, String)*)
        .withRequestTimeout(_ : Duration)
        .stream())
      .expects(url, method, headers, timeout)
      .returning(response)

问题是withHttpHeaders-这实际上需要使用（字符串，字符串）*，但是当我如上所述指定该类型时，会出现这样的编译器错误：

[error]  found   : Seq[(String, String)]
[error]  required: (String, String)
[error]       .withHttpHeaders(_: Seq[(String, String)])

我需要为此方法指定什么类型，因为（String，String）不正确。该方法的实际定义是：

  override def withHttpHeaders(headers: (String, String)*): Self

Answer 1

尝试

(xs: Seq[(String, String)]) => mockWsClient.withHttpHeaders(xs: _*)
