cors

问题 Ive followed instructions at https://cloud.google.com/functions/docs/writing/http#functions_http_cors-python So my code has this at the end # Set CORS headers for the preflight request if request.method == 'OPTIONS': # Allows GET requests from any origin with the Content-Type # header and caches preflight response for an 3600s headers = { 'Access-Control-Allow-Origin': '*', 'Access-Control-Allow-Methods': 'GET', 'Access-Control-Allow-Headers': 'Content-Type', 'Access-Control-Max-Age': '3600'

问题 I'm trying to display images on a canvas. The images are hosted on S3. CORS is set up on AWS, and the CrossOrigin attribute is set to anonymous in the script. Everything works fine on Firefox — but images are not being loaded on Chrome and Safari. Errors Safari: Origin https://www.example.com is not allowed by Access-Control-Allow-Origin. http://mybucket.s3.amazonaws.com/bubble/foo.PNG [Error] Failed to load resource: Origin https://www.example.com is not allowed by Access-Control-Allow

问题 I am trying to upload large files from an Angular 9.0 front end to a Web Api .net core 3.1 back end. I am following this tutorial https://code-maze.com/upload-files-dot-net-core-angular/. It all works perfect up to the default max file size of 28.6 mb, once I go above this file size I get the following cors error: 'Access to XMLHttpRequest at [localhost] from origin [localhost] has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.'

问题 I'm trying to create an audio visualization for a podcast network, using the Web Audio API with createMediaElementSource() very similarly to the model explained in this tutorial. So far I've gotten it to work fine in Chrome, and you can see it here (note: click on the red box to start it). Update : Based on discussion in the comments, it’s now become clear that the problem happens because the request gets redirected to another URL, by way of a 302 redirect. However, Safari refuses to work,

问题 I understand the CORS policy and since the server is not set to accept CORS requests, I should not be able to download the CSV file from a different origin. However the server seems perfectly happy to fullfill the request when it is made from VBA in Excel. So why can't I grab the same file using Javascript? In Excel: Sub transfercsv() sCSVLink = "https://subdomain.domain.com/specific_page/pending_csv?var=specificLocation" sfile = "Filename_Specific_Location_" & Year(Date) & "-" & Month(Date)

问题 I'm getting "Script Error." when catching errors in window.onerror, even with properly (I think) configured CORS headers on S3. CORS config: <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>POST</AllowedMethod> <AllowedMethod>PUT</AllowedMethod> <AllowedMethod>HEAD</AllowedMethod> <MaxAgeSeconds>3000</MaxAgeSeconds> <AllowedHeader>*<

问题 So I am trying to load the data from a REST source into my Angular 6 app using http: HttpClient from '@angular/common/http' . Calling the app in the browser using ng serve --open though doesn't do the job. I assume CORS to be the problem here. I guess I either have to set the server or the client headers with Access-Control-Allow-Origin or something, but I have already tried multiple ways without any success in making this simple REST call work. So what follows below is what I coded. Calling
