问题 Issue I have a page where users can upload files with the help of FormData and an XMLHttpRequest . Uploading the file works fine. But the upload.onprogress is only working when uploading from an HTTP connection . HTTPS HTTP I've tested this on Heroku and on an Amazon EC2 instance. But it's always the same: Progress is shown when uploading via HTTP Progress event is never triggered when uploading via HTTPS Javascript (Angular 7) const xhr = new XMLHttpRequest(); let progress = 0; /** THIS

问题 This question already has answers here : How to send data in request body with a GET when using jQuery $.ajax() (4 answers) Closed last year . I have to interact with an API that takes parameters from the body of a GET request. I know this might not be the best idea, but it is the way the API was built. When I try building a query with XMLHttpRequest , it looks like the payload is simply not sent. You can run this and look in the network tab; the request is sent, but there is no body (tested

问题 I want to administratively prevent a whole class of XSS attacks by not allowing anything on my page to send XHR/XMLHttpRequest (or other?) requests to other domains than the domain hosting the page. Is that possible? I thought I could do that with Cross-Origin Resource Sharing (CORS), but it seems I was wrong. If a page hosted on domain-a.com tries to make an XHR request to domain-b.com, CORS can be used on domain-b.com pages to control whether or not that is allowed. So if something on the

问题 How to block requests from a certain URL using JavaScript? For example, the manual way to do so on chrome will be to open the inspect page, go to network and block from there. But I need to block requests from certain URLs for an automated test that i am writing in JavaScript (using testcafe, if that offers any help). Here are screenshots of manually blocking a request from chrome, I want to do the same thing automatically in my test/JavaScript: ScreenShot1 Screenshot2 Thank you. Edit: I

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 have checked that both browser-generated page and VBA XMLHTTP request's string response have the same tree structure, with a tag being a child of aside . Unfortunately when I want to return bookie name, which is title attribute of a , I get an error accessing 1st child of aside .
