如何在 Rails 功能测试中发送原始帖子数据? [英] How to send raw post data in a Rails functional test?

问题描述

我希望将原始发布数据(例如未参数化的 JSON)发送到我的一个控制器进行测试:

I'm looking to send raw post data (e.g. unparamaterized JSON) to one of my controllers for testing:

class LegacyOrderUpdateControllerTest < ActionController::TestCase
  test "sending json" do
    post :index, '{"foo":"bar", "bool":true}'
  end
end

但这给了我一个 NoMethodError: undefined method `symbolize_keys' for # 错误.

but this gives me a NoMethodError: undefined method `symbolize_keys' for #<String:0x00000102cb6080> error.

在 ActionController::TestCase 中发送原始帖子数据的正确方法是什么?

What is the correct way to send raw post data in ActionController::TestCase?

这是一些控制器代码:

def index
  post_data = request.body.read
  req = JSON.parse(post_data)
end

推荐答案

我今天遇到了同样的问题并找到了解决方案.

I ran across the same issue today and found a solution.

在您的 test_helper.rb 中，在 ActiveSupport::TestCase 中定义以下方法:

In your test_helper.rb define the following method inside of ActiveSupport::TestCase:

def raw_post(action, params, body)
  @request.env['RAW_POST_DATA'] = body
  response = post(action, params)
  @request.env.delete('RAW_POST_DATA')
  response
end

在您的功能测试中，像 post 方法一样使用它，但将原始帖子正文作为第三个参数传递.

In your functional test, use it just like the post method but pass the raw post body as the third argument.

class LegacyOrderUpdateControllerTest < ActionController::TestCase
  test "sending json" do
    raw_post :index, {}, {:foo => "bar", :bool => true}.to_json
  end
end

我在使用

request.raw_post

代替

request.body.read

如果你看看 源代码 你会看到 raw_post 只是包装了 request.body.read 并检查了这个 RAW_POST_DATA 在request env 哈希.

If you look at the source code you'll see that raw_post just wraps request.body.read with a check for this RAW_POST_DATA in the request env hash.
