cors

问题 For the following ajax post request for Flask (how can I use data posted from ajax in flask?): $.ajax({ url: "http://127.0.0.1:5000/foo", type: "POST", contentType: "application/json", data: JSON.stringify({'inputVar': 1}), success: function( data ) { alert( "success" + data ); } }); I get a Cross Origin Resource Sharing (CORS) error: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code

问题 I am working on an web application where I would like to allow the user to push data to her own Google spreadsheet. Firstly I tried to use Google APIs Client Library for JavaScript but it doesn't seem to cover the Spreadsheet API (https://developers.google.com/apis-explorer/#p/). Then I decided to use directly the Google Spreadsheets API version 3.0. I manage to retrieve the user's spreadsheets using jQuery and JSONP : $.ajax({ url: 'https://spreadsheets.google.com/feeds/spreadsheets/private

问题 Iknow this has been asked often before, but after 3days trying to fix this i clearly need help. I've had a problem for a while now. I been trying to do something like this (This is a simplified code): var media = Array(); $(document).ready(function(){ img = new Image(); img.crossOrigin = "*"; img.src = "http://domain.com/pics/picture.svg"; img.width = 200; img.height = 300; img.onload = function(){ media['test'] = img; ///var layer = img; $.jCanvas({ fromCenter: false }); $("#collider")

问题 Attempting to implement an ajax login / signup process (no refresh site with authentication). Using cookies for preserving state. I thought I'd have this right by now but for some reason browser doesn't set cookies after it gets them back from the server. Can anyone help? Here are the request and response headers: Request URL:http://api.site.dev/v1/login Request Method:POST Status Code:200 OK Request Headers Accept:application/json, text/plain, */* Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0

问题 I am trying to send a CORS request for a JSON payload. I control both the server and the client. I'm following along here: https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS?redirectlocale=en-US&redirectslug=HTTP_access_control The server has a custom header that must be sent along with every request. This custom header therefore makes the request 'not simple' and thus the request must be preflighted with an OPTIONS request. I can see jquery making the OPTIONS request, but it

问题 I've set up Cross-Origin Resource Sharing on a server (Jetty using the CrossOriginFilter) and it works perfectly on IE8 and Firefox. On Chrome, it just ... doesn't. $.ajax({ url : crossOriginURL, type : "GET", error : function(req, message) { alert(message); }, dataType : "json" } ); The error function is invoked, with the helpful message "error". It seems to be making the request, but without any of the headers you'd expect. If the URL is from the same origin, it works fine. 回答1: I have

问题 A simple GET request with no custom headers. The response is returned as expected. The data in the body is accessible, but not the headers. When I try to access the "etag" header, browsers raise an exception : Refused to get unsafe header "etag" Chrome, Safari and Firefox all behave the same. I didn't test it on IE. What am I missing here? 回答1: Only simple response headers are exposed when using CORS. Simple response headers are defined here. ETag is not a simple response headers. If you want

问题 I tried to follow the steps at http://enable-cors.org/server_aspnet.html to have my RESTful API (implemented with ASP.NET WebAPI2) work with cross origin requests (CORS Enabled). It's not working unless I modify the web.config. I installed WebApi Cors dependency: install-package Microsoft.AspNet.WebApi.Cors -ProjectName MyProject.Web.Api Then in my App_Start I've got the class WebApiConfig as follows: public static class WebApiConfig { public static void Register(HttpConfiguration config) {

问题 I had developed a PhoneGap app which is now being transformed to a mobile website. Everything works smoothly besides one small glitch. I use a certain third party API via a POST request, which works fine in the app, but fails in the mobile website version. After a closer look it seems like AngularJS (I guess the browser actually) is first sending an OPTIONS request. I learned a lot today about CORS, but I can't seem to figure out how to disable it altogether. I do not have access to that API
