http-options-method

问题 This question already has an answer here : Missing token in CORS header ‘Access-Control-Allow-Headers’ from CORS preflight channel (1 answer) Closed 8 months ago . Although the OPTIONS returns * for Allow-Headers I'm getting the following CORS response.

While the OPTION

问题 According to http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.2 the only response ever mentioned regarding an HTTP OPTIONS request is a 200. However, there seem to be cases such as when the content-length is 0 that a 204 would be more appropriate. Is it appropriate for an HTTP OPTIONS request to return a 204? 回答1: Yes, it can return 204. Or 400. Or 404. There is no general restriction as to what status codes a method can return. Also note that it's time to stop looking at RFC 2616.

问题 My Sencha Touch app is posting a form to my asp.net-mvc-3 WebService, but instead of sending POST it's sending OPTIONS . I'm reading a similar thread here, but I just don't know how to handle the OPTIONS method in my code. I did try adding the [AllowAjax] attribute to my Action, however it doesn't seem to exist in MVC3. OPTIONS /GetInTouch/CommunicateCard HTTP/1.1 Host: webservice.example.com Referer: http://192.168.5.206/ Access-Control-Request-Method: POST Origin: http://192.168.5.206 User

问题 On client side I'm using Ajax.post (jquery 1.5) with json. On server side I'm using rest resteasy-jaxrs-2.0.1.GA. I found somewhere that i should add couple of headers to server response and I've done with following filter: public void doFilter( ServletRequest req, ServletResponse res, FilterChain filterChain) throws IOException, ServletException { MyServletRequestWrapper httpReq = new MyServletRequestWrapper((HttpServletRequest)req); HttpServletResponse httpRes = (HttpServletResponse)res;

问题 Introduction I've read the following: Hypertext Transfer Protocol (HTTP) is the life of the web. It's used every time you transfer a document, or make an AJAX request. But HTTP is surprisingly a relative unknown among some web developers. The HTTP verbs comprise a major portion of our “uniform interface” constraint and provide us the action counterpart to the noun-based resource. The primary or most-commonly-used HTTP verbs (or methods, as they are properly called) are POST, GET, PUT , and

问题 I am trying to make OPTIONS requests work with django but I am currently only getting 405. An answer I got here was that the server does not handle the OPTIONS request. This is the View that handles the request: from django.views.generic import View from piston.utils import coerce_put_post class TheView(View): @staticmethod def find_stuff(params): ... @staticmethod def do_stuff(params): ... @staticmethod def do_other_stuff(params): ... @staticmethod def delete_some_stuff(params): ... @method

问题 I tried to find out the solution for one of the existing question Error Handling in HTTP Ajax Call using $fetch Javascript - I tried to reproduce the said scenario. I found the issue, that is the HTTP call triggers the HTTP OPTIONS method. Finally its not returning any HTTP Status code. I checked the Netwok, its shows an empty status code and the status signal is grayed Refer Preflight Table Request: https://docs.microsoft.com/en-us/rest/api/storageservices/preflight-table-request Kindly

问题 I use backbone.js' s model. When i save the model, it sends HTTP OPTIONS method to server-side on firefox, but sends HTTP POST method with safari. I know it is not an issue about backbone.js, it is about CORS. I will just check if method, GET, POST, PUT and DELETE on server-side, i will not do a job with HTTP OPTIONS method. my requested url is my api: api.foo.com and api requested from: bar.com so, how can i control in all browsers request my api.foo.com with HTTP POST not OPTIONS? and how
