问题 I'm developing a android app using Ionic Framework based in a AngularJS web site I developed using Jhipster. As I already have server code running in my web application, I've choose Ionic to work as UI and call server when needed, but I'm having some issues in my development enviroment. As I run my application using Ionic serve, I need use CORS to make requests to server. My web application was developed using CSRF token with Spring Security I'm using Apache CORS filter configured this way:

问题 I have a PHP file which generates a JSON document. I've set the header as follows but am still getting an error. header('Access-Control-Allow-Origin: *'); header('Content-Type: application/json'); Error message: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://mysubdomain.mydomain.com' is therefore not allowed access. I've tried explictly allowing mysubdomain.mydomain.com using header('Access-Control-Allow-Origin: https://mysubdomain.mydomain.com')

问题 I'm using a React web app and trying to upload a file to AWS S3. I've tried everything both locally ( localhost:3000 ) and when deployed to production (Vercel serverless functions). I first use a fetch to retrieve a presigned url for the file upload, which works perfectly: module.exports = async (req, res) => { let {fileName, fileType} = req.body; const post = await s3.createPresignedPost({ Bucket: BUCKET_NAME, Fields: { key: fileName }, ContentType: fileType, Expires: 60 }); res.status(200)

问题 According to MDN, POST requests are not preflighted if the Content-Type is any of application/x-www-form-urlencoded , multipart/form-data , or text/plain . But isn't multipart/form-data exactly as unsafe as application/xml ? For instance I would expect cross-origin POST requests to the url http://bank.com/money-orders/ to always be disallowed, regardless of the content type the endpoint accepts. 回答1: Because: Before CORS was ever even conceived of, it was possible to send a cross-origin POST

And the only

问题 I would like my CorsFilter to do the following: // populating the header required for CORS response.addHeader( "Access-Control-Allow-Origin", "https://*.myDomain.com"); The whole idea is to allow the following domains to make a request: sub1.myDomain.com, sub2.myDomain.com, sub3.myDomain.com .... sub100.myDomain.com This didn't work for me. How can I achieve this? Iv'e tried: response.addHeader( "Access-Control-Allow-Origin", "*.myDomain.com"); as well with no success. 回答1: I am having the
