Api :: V1 :: UsersController #create中的ActionController InvalidAuthenticityToken

您需要在application_controller.rb中进行以下更改

更改

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
end

至

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :null_session
end

编辑

更好的方法是跳过特定控制器的身份验证

class Api::V1::UsersController < ApplicationController
  skip_before_action :verify_authenticity_token

  respond_to :json
  # ...
end
