使用ajax编辑帖子时,我在浏览器中出错。 XMLHttpRequest无法加载http://example.com/posts/100。 Access-Control-Allow-Methods不允许使用方法PUT。
在rails服务器中:
Started OPTIONS "/posts/100" for 127.0.0.1 at 2014-11-14 11:51:39 -0800
Processing by ApplicationController#handle_options_request as */*
Parameters: {"path"=>"posts/100"}
我经历了几个解决方案并做了类似的事情 在rotues.rb中:
match '*path', :controller => 'application', :action => 'handle_options_request', :constraints => {:method => 'OPTIONS'}
在application_controller.rb
中 def handle_options_request
headers['Access-Control-Allow-Origin'] = request.env['HTTP_ORIGIN']
headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS'
headers['Access-Control-Max-Age'] = '1000'
headers['Access-Control-Allow-Headers'] = '*,x-requested-with'
head(:ok) if request.request_method == "OPTIONS"
end
任何人都有解决方案来解决它。也尝试使用rack-cors,但它不起作用
答案 0 :(得分:2)
尝试将此行更改为(添加PUT):
headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS, PUT'
