Question

I'm developing an application which backend is being written in rails 5 api (beta version).

My API will have some versions, and I'm using this approach to address versioning:

https://github.com/iamvery/rails-api-example/blob/master/config/routes.rb

Rails.application.routes.draw do
  def api_version(version, &routes)
    api_constraint = ApiConstraint.new(version: version)
    scope(module: "v#{version}", constraints: api_constraint, &routes)
  end

  api_version(1) do
    resources :articles, only: :index
  end

  api_version(2) do
    resources :articles, only: :index
  end
end

问题是当我没有指定版本时，它会向我显示（obviuos）错误（ActionController::RoutingError: No route matches [GET] \...）。

但我想使用最新的api版本路由而不是抛出错误。

Answer 1

您的routes.rb文件

app/lib

在class ApiConstraints def initialize(options) @version = options[:version] @default = options[:default] end def matches?(req) @default || req.headers['Accept'].include?("application/vnd.marketplace.v#{@version}") end end目录中创建新的api_constraints.rb文件

private String url;

@Factory(dataProvider = "urls", dataProviderClass = URLProvider.class)
public EndToEndTest(String url) {
  this.url = url;
}

Answer 2

我会添加一个根路由，并使用一个简单的重定向，如下所示：

root to: redirect('/api/v2')

我相信这可以通过一些更改来动态完成，如下所示：

@versions = []

def api_version(version)
  @versions << versions
  # The rest of your code..
end

root to: redirect("/v#{@versions.max}")

我希望这会有所帮助。
