设置http状态码 [英] Setting http status codes

问题描述

redirect_to browse_path(asset.parent_id), notice: "successfully created file!", status: 201

201 是您创建资源时应设置的状态.虽然上述方法适用于创建操作，但其操作的规范不再适用:

201 is the status you should set if you've created a resource. While the above method works for a create action, the spec for its action no longer does:

subject { response }
describe '.create' do
    context 'when orphan' do
      before do
        post :create, asset: { parent_id: nil, uploaded_file: file }
      end

      it { should have_http_status 201 }
      it { should redirect_to '/' }
    end
end

状态期望通过，但redirect_to期望失败:

The status expectation passes, but the redirect_to expectation fails:

Expected response to be a <redirect>, but was <201>

我接受它不再是 302 重定向，但它仍然将用户重定向到新路由(我想测试).如果我将其设置为 302 而不是 201 的错误"代码，则 redirect_to 规范通过:

I accept that it's no longer a 302 redirect, but it does still redirect the user to a new route (which I want to test). The redirect_to spec passes if I set it to the "wrong" code of 302, rather than 201:

redirect_to browse_path(asset.parent_id), notice: "successfully created file!", status: 302

那么我应该为设置状态代码而烦恼吗?我承认我实际上不知道浏览器如何使用它们，如果我在我的操作中煞费苦心地设置它们或不设置它们(只需使用 302 重定向和 200 次成功)，我的应用程序也能正常运行.

so should I bother with setting status codes? I'll admit I actually have no idea how the browser uses them and my applications functions just as well if I painstakingly set them in my actions or don't (just use 302 redirects and 200 successes).

如果状态代码很重要，我应该如何让上述规范通过?

If status codes are important, how should I get my above specs to pass?

推荐答案

您可以在 rspec 中断言 response.body 或其他响应属性.在这种情况下，您所追求的是 response.header["Location"]

You can assert off response.body or other response attributes within rspec. In this case the thing you are after is response.header["Location"]

您可以选择使用 capybara/rspec 来避免问题，您可以在其中断言 current_url 并仍然断言状态代码.

You can choose to dodge the problem with capybara/rspec where you can assert current_url and still assert the status code.

redirect_to 只是一个愚蠢的中级助手，你需要在响应中达到稍低的级别.水豚的东西或更高的级别才能到达你想去的地方.

redirect_to is just a dumb mid level helper and you need to reach to a slightly lower level in response.something or higher level with capybara to get where you want to be.
