我的前端是一个单独的Brunch.io AngularJS应用程序.由于我的前端运行于
http://localhost:3333,而我的凤凰后端运行于
http://localhost:4000,因此在尝试POST到
http://localhost:4000/api/users/register时出现此错误
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3333' is therefore not allowed access. The response had HTTP status code 404.
所以我认为这是一个CORS问题.如何在凤凰中发送标题?
这是我的router.ex
scope "/api",MyApp do pipe_through :api # Users post "/users/register",UserController,:register end
这是我的UserController
defmodule MyApp.UserController do use MyApp.Web,:controller def register(conn,params) do IO.puts(inspect(params)) conn |> put_status(201) |> json %{ok: true,data: params} end end
你有几个选项可以为你连接起来:
