Rails 关于 Rails 中的路由问题
我再 routers 中写下如下的路由，然后 POST 地址 /weixin，出现错误 No route matches [POST] "/weixin"
scope :path => '/weixin', :via => :post do
match "/", :to => 'weixin#method_text', :constraints => lambda{|request| Nokogiri::XML(request.body.read).xpath('//MsgType').text == 'text'}
match "/", :to => 'weixin#method_image', :constraints => lambda{|request| Nokogiri::XML(request.body.read).xpath('//MsgType').text == 'image'}
match "/", :to => 'weixin#method_location', :constraints => lambda{|request| Nokogiri::XML(request.body.read).xpath('//MsgType').text == 'location'}
match "/", :to => 'weixin#method_event', :constraints => lambda{|request| Nokogiri::XML(request.body.read).xpath('//MsgType').text == 'event'}
end
但是我这样写是可以的
scope :path => '/weixin', :via => :post do
match "/", :to => 'weixin#method_event', :constraints => lambda{|request| Nokogiri::XML(request.body.read).xpath('//MsgType').text == 'event'}
end
不太懂是什么原因，求教各位
我这么写的可以，加个解析 xml 的 gem
scope :path => "/weixin", :via => :post do
match "/", :to => 'weixin#method_text', :constraints => lambda { |request| request.params[:xml][:MsgType] == 'text' }
match "/", :to => 'weixin#method_image', :constraints => lambda { |request| request.params[:xml][:MsgType] == 'image' }
match "/", :to => "weixin#method_location",:constraints => lambda { |request| request.params[:xml][:MsgType] == 'location' }
match "/", :to => "weixin#method_event",:constraints => lambda { |request| request.params[:xml][:MsgType] == 'event'}
end
gem ‘actionpack-xml_parser’, ‘~> 1.0.1’

你应该使用了 actionpack-xml_parser 这个 gem 吧，我试了下这个 Gem，按照教程没法使用。

config.middleware.insert_after ActionDispatch::ParamsParser, ActionDispatch::XmlParamsParser
这个加了没？
@liuminhan 加了这一句没法启动了
uninitialized constant ActionDispatch::XmlParamsParser (NameError)

提醒：xml parser 以前出过远程执行漏洞，后来 rails 就干脆剥离了，目前维护热度肯定不高，为了安全最好别用。
