Ruby on rails RubyonRails：如何仅检索POST和PATCH参数

因此，我只想在数据是POST或补丁请求时对其进行一些修改。在这个问题（）中，有一种获取POST和获取参数的方法，但我已经搜索过了，似乎没有一种方法可以只获取补丁数据。

有一系列方法来检查HTTP谓词，这些方法包括：

get？

，

POST？

，

PATCH？

和

put？

因此，以下几点应该可以做到：

def some_action
  request.patch? # only patch requests
  # or
  request.request_method == :patch
  # and if you are intrested in both PATCH and POST... combine them!
  request.patch? || request.post?
end 

# in some controller's method

if request.patch? || request.post?
  # do your work here
end

请注意，您可能对限制路由定义中使用的HTTP谓词感兴趣。使用特定动词定义操作会限制处理不使用同一动词的请求：

# routes.rb
put '/orders/:id/refuse' => 'orders#refuse'
# so your refuse method accepts only PUT requests

我相信这会奏效：

def some_action
  request.patch? # only patch requests
  # or
  request.request_method == :patch
  # and if you are intrested in both PATCH and POST... combine them!
  request.patch? || request.post?
end 

# in some controller's method

if request.patch? || request.post?
  # do your work here
end

因此，如果我访问if语句中的params对象，可以保证它只包含来自PATCH或POST的数据，而不包含GET（例如？@user2968505）。因此如果我访问if语句中的params对象，它保证只包含来自补丁或POST的数据，并且没有GET，例如？@user2968505。
