我的前端是一个单独的Brunch.io AngularJS应用程序。由于我的前端在http://localhost:3333上运行,而我的凤凰后端在http://localhost:4000上运行,因此在尝试发布到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。如何在凤凰城发送标题?
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
