Bug: Properly serialize and deserialize "Blob" and "File" on Firefox

[iameli]

Hi,

It looks like xdomain handles the contents of FormData properly, but I'm working with an API where we pass raw data around sometimes -- Blob and File types. This works fine with Chrome and IE10 but fails on Firefox (DataCloneError) with their longstanding Blob postMessage nonsense. https://bugzilla.mozilla.org/show_bug.cgi?id=722126

I'm looking at the stuff that serializes and deserializes FormData on the masters and slaves -- I think adding support for Blob and File wouldn't be too difficult -- it's the same method, just without the FormData wrapper. Probably I'll submit a PR this weekend if I'm on the right track here.

Thanks!

It should already be converting files and blobs to a uint8array, let me read through the code though, haven't looked at it for quite a while

HI, Before including Xdomain.min.js in the project while fetching the stream(MemoryStream) response from WEB API using ActionResult and then converted that blob data using below code snippet into pdf file format.

var blob = new Blob([res._body], { type: 'application/pdf' }); this.fileUrl = this.sanitizer.bypassSecurityTrustResourceUrl(window.URL.createObjectURL(blob)); if (callingFrom === 'download') { let element = this.downloadLink.nativeElement; element.href = this.fileUrl.changingThisBreaksApplicationSecurity; element.click(); } Once I include Xdomain plugin in the project to fix CORS issue stream response is getting junk like below: image

Please help me in this It's taking time but coundn't find any solution. Please respond AQAP.

Thanks in advance.
