使用ajax編輯帖子時,瀏覽器出現錯誤。 XMLHttpRequest無法加載http://example.com/posts/100。 Access-Control-Allow-Methods不允許方法PUT。Access-Control-Allow-Methods不允許使用方法PUT
在軌服務器:
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"}
我通過幾個解決方案去了,的確在rotues.rb像這樣 :在application_controller.rb
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
match '*path', :controller => 'application', :action => 'handle_options_request', :constraints => {:method => 'OPTIONS'}
有解決方案來解決它。也可以嘗試架-CORS,但它不工作
