cors

问题 Using JQuery 1.8.2 I'm making a CORS request to an app from one AppServer ( Front ) to another AppServer ( Back ) server. When i make the following Ajax calls from Front , the 302 response (security check) from Back is honored, but my JSESSIONID cookie is not stored: $.ajax({ url : url, dataType : 'html', success : function(data, status, xhr) { $(dataContainer).append(data); }, complete: function(xhr, status, error) { if (xhr.status != 200) { $.logger(xhr.getResponseHeader('Location')); } } }

问题 I'm missing something here. I was struggling to get the API call to work. Then I split the url up like below and it works -literally once. After that it fails to work again. I swear I did not change something. How do you go about it in AXIOS? Error message is: XMLHttpRequest cannot load http://magicseaweed.com/api/W2Z26fXscpELi7nPB0svfqcGj9FtGO9e/forecast/?spot_id=228. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not

问题 Trying to secure my ASP.NET Web API-2 using Basic Authentication but it is always ending up with error: 401/Unauthorized Authorization has been denied for this request. Below are my controller and ajax request code snippet alongside the request and response headers. BasicAuthenticationHandler.SendAsync always runs successfully up-till: return base.SendAsync(request, cancellationToken); Q: Then WHY it ends up as 401/unauthorized ? If I remove [Authorize] from the controller action then it

问题 I followed the example: http://arunranga.com/examples/access-control/credentialedRequest.html from this page: http://arunranga.com/examples/access-control/ The example work in Firefox, but not Safari, anyone have tried in implementing CORS cross domain cookie handling, and being success in Safari? Thanks. 回答1: This sounds like a Safari bug. I just verified that cross-domain cookies aren't being set in Safari. Cross-domain cookies are working in Chrome, so this may be fixed in WebKit and the

问题 I am writing a graphql server component on AWS Lambda (NOT using graphql-server). On the client side I'm using apollo-client. On the response of the lambda function I'm setting const response = { statusCode: 200, headers: { "Access-Control-Allow-Origin": "*" // Required for CORS support to work }, body: JSON.stringify({ result: 'mock data', input: event, }), }; callback(null, response); On the client side using ApolloClient I get the following error Response to preflight request doesn't pass

问题 Basic scenario I'm loading several images on the client side. Some of them are from another domain, some are not. Some I may be able to access using the crossOrigin attribute, some not. The basic requirement is to retrieve a dataURL for the images where possible. Question After drawing the image to the canvas element (which I need to to to get a dataURL, right?), how can I check, without a try ... catch block, whether the canvas has been tainted ? If the canvas is tainted, I can't use

问题 I would like to do cross origin communication using Grails in server side. The only documentation that I found is this one https://grails.org/plugin/cors but this is for an old version of Grails. The other documentation that I found is for spring: https://spring.io/guides/gs/rest-service-cors/ so I added the file SimpleCorsFilter.groovy to init/myproject/ folder, but I don't know how to wire this component into resources.groovy 回答1: So, if you got here using grails 3.2.+ you can use the

问题 I am trying to login through http://localhost:3000 using HTTP `POST. I am getting the following: XMLHttpRequest cannot load http://localhost:8080/api/auth/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. I have configured my Spring 5.0.0.M4 and Spring-Security 4.2.1.RELEASE application like that: @SpringBootApplication public class SpringBootApp extends WebMvcConfigurerAdapter { private boolean

问题 I swear this has happened so many times to me that I actually hate CORS. I have just split my application in two so that one handles just the API side of things and the other handles the client side stuff. I have done this before, so I knew that I needed to make sure CORS was enabled and allowed all, so I set this up in WebApiConfig.cs public static void Register(HttpConfiguration config) { // Enable CORS config.EnableCors(new EnableCorsAttribute("*", "*", "*")); // Web API configuration and
