Question

您好我正在尝试通过此测试

  test "authentication plug should return 401 when not authenticated", %{conn: conn} do  
    conn = Map.put(conn, :params, %{})
    conn =  ChaacServerWeb.Plugs.Authentication.call(conn, nil)
    assert json_response(conn, 401)["errors"] != %{}
  end

这是我的插件

  def call(conn, _) do
     token = List.first(get_req_header(conn, "authorization"))
     case Accounts.validate_token(conn.params["user_id"], token) do
     {:ok, valid_token} -> conn
     err -> 
       conn 
       |> halt() 
       |> ChaacServerWeb.FallbackController.call(err)
     end
  end

我收到此错误

1) test authentication plug should return 401 when not authenticated (ChaacServerWeb.AuthenticationTest)                                                                               test/chaac_server_web/plugs/authentication_test.exs:26                                           
** (RuntimeError) cannot render template :"401" because conn.params["_format"] is not set. 
Please set `plug :accepts, ~w(html json ...)` in your pipeline.                          
code: conn =  ChaacServerWeb.Plugs.Authentication.call(conn, nil)                         
stacktrace:

我知道我需要在我的测试设置中以某种方式调用plug :accepts, [:json]但是我该怎么做？谢谢

（编辑）我的路由器在我的管道中有plug :accepts, [:json]

我刚刚做了

test "authentication plug should return 401 when not authenticated", %{conn: conn} do  
  conn = Map.put(conn, :params, %{"_format" => "json"})
  conn =  ChaacServerWeb.Plugs.Authentication.call(conn, nil)
  assert json_response(conn, 401)["errors"] != %{}
end

感觉abit hacky但它对我有用。

您可以使用put_req_header：

setup %{conn: conn} do
    {:ok, conn: put_req_header(conn, "accept", "application/json")}
end

如何测试调用action_fallback控制器的插件？
