即使指定了录像带

我有一个带有用户模型的仅API的RoR应用。通过Twilio / Authy（使用this gem）对用户进行身份验证。每个用户has_one authy_user都使用dependent: :destroy模型来存储真实信息。

authy_user模型具有一个before_destroy钩子，该钩子通过authy gem连接到authy api并在那里删除用户。

authy_user规范运行得很好，并且我已经通过authy api为registering和deleting用户录制了录音带。

一部分authy_user：

describe "delete user" do
 before do
  @user = create(:user_with_authy_user)
 end

 context "user is registered" do
  it "deletes user in authy and locally" do
    VCR.use_cassette("authy_delete_user") do
      expect {
        @user.authy_user.destroy
      }.to change { AuthyUser.count }.by(-1)
     end
   end
 end
end

（如果我将其从@user.authy_user.destroy更改为@user.destroy，则会失败，并出现以下相同的错误）

我的问题是user请求规范，尤其是删除用户的规范。

以下是失败的规范：

describe "DELETE /user" do
  context "user exists" do
    before do
      @user = create(:user_with_authy_user)
      @token = JWTService.issue_access_token user: @user, provider: "authy"
    end

    it "deletes the user" do
      expect {
        VCR.use_cassette("authy_delete_user") do
          delete(user_path, headers: { "X-Auth-Token": @token })
        end
      }.to change { User.count }.by(-1)
      expect(status).to eq(204)
      expect(body).to be_blank
    end
  end
end

这是失败的地方：

  1) Users DELETE /user user exists deletes the user
 Failure/Error: Authy::API.delete_user id: authy_id

 VCR::Errors::UnhandledHTTPRequestError:


   ================================================================================
   An HTTP request has been made that VCR does not know how to handle:
     POST https://api.authy.com/protected/json/users/delete/92962960

   There is currently no cassette in use. There are a few ways
   you can configure VCR to handle this request:

     * If you're surprised VCR is raising this error
       and want insight about how VCR attempted to handle the request,
       you can use the debug_logger configuration option to log more details [1].
     * If you want VCR to record this request and play it back during future test
       runs, you should wrap your test (or this portion of your test) in a
       `VCR.use_cassette` block [2].
     * If you only want VCR to handle requests made while a cassette is in use,
       configure `allow_http_connections_when_no_cassette = true`. VCR will
       ignore this request since it is made when there is no cassette [3].
     * If you want VCR to ignore this request (and others like it), you can
       set an `ignore_request` callback [4].

看起来好像叫use_cassette，但是也许它在路上某个地方被设置了吗？ 是否与dependent: :destroy和user之间的authy_user关系有关？

感谢您的帮助，如果您需要更多信息，请告诉我。

答案 0 :(得分：2)

也许，每次您所做的请求中的某些内容都会发生变化，例如HTTP标头，时间戳记，并且由于您没有指定VCR来记录新交易，因此它将失败。

我会使用

对其进行调试 
VCR.use_cassette("authy_delete_user", record: :new_episodes)

查看是否记录了一个新的录像带并进行比较，以查看输出，看看有什么变化。

默认情况下，如果请求中的任何内容发生更改，则会写入新的卡带或引发错误（您的情况）。在这种情况下，您可以指定如何匹配录像带数据和请求，例如，使用match_requests_on，请参见here
