How do you test an AJAX request with RSpec/RoR?
提问by user480826
I'm fairly new to RoR and recently started learning BDD/Rspec for testing my application. I've been looking for a way to spec an AJAX request, but so far I haven't found much documentation on this at all.
我对 RoR 还很陌生，最近开始学习 BDD/Rspec 来测试我的应用程序。我一直在寻找一种规范 AJAX 请求的方法，但到目前为止我还没有找到太多关于此的文档。
Anyone know how to do this? I'm using rails 2.3.8, rspec 1.3.0 and mocha 0.9.8 for my stubs (which I'm also in the process of learning...)
有人知道怎么做吗？我正在使用 rails 2.3.8、rspec 1.3.0 和 mocha 0.9.8 作为我的存根（我也在学习......）

If you're talking about testing it inside your controller specs, where you normally call
如果您正在谈论在您的控制器规格中测试它，您通常会在那里调用
get :index
to make an HTTP request to the index action, you would instead call
要向索引操作发出 HTTP 请求，您可以调用
xhr :get, :index
to make an XmlHttpRequest (AJAX) request to the index action using GET.
使用 GET 向索引操作发出 XmlHttpRequest (AJAX) 请求。

Since Rails 5.0 (with RSpec 3.X), try setting xhr: truelike this:
从 Rails 5.0（使用 RSpec 3.X）开始，尝试设置xhr: true如下：
get :index, xhr: true
Background
背景
Here's the relevant code in the ActionController::TestCase. Setting the xhrflag ends up adding the following headers:
这是ActionController::TestCase 中的相关代码。设置xhr标志最终会添加以下标题：
if xhr
@request.set_header "HTTP_X_REQUESTED_WITH", "XMLHttpRequest"
@request.fetch_header("HTTP_ACCEPT") do |k|
@request.set_header k, [Mime[:js], Mime[:html], Mime[:xml], "text/xml", "*/*"].join(", ")
end
end

Syntax changed a bit for Rails 5 and rspec > 3.1(i believe)
Rails 5 和 rspec > 3.1 的语法略有变化（我相信）
for POST requests:
对于 POST 请求：
post :create, xhr: true, params: { polls: { question: 'some' } }
you now need explicitely set params
你现在需要明确设置 params
for GET requests:
对于 GET 请求：
get :action, xhr: true, params: { id: 10 }
for rails 4 and rspec <= 3.1
对于 rails 4 和 rspec <= 3.1
xhr post :create, { polls: { question: 'some' } }
GET requests:
获取请求：
xhr get :show, id: 10
