Sending FormData about xhr HOT 2 CLOSED

It is possible and it should work. There's no difference for xhr between string and formdata as body. XMLHttpRequest should just handle that (unless you're in a browser that has a bug)

I remember sending multipart file uploads even without setting the content-type header.

            throw new Error("Unsupported browser");
        }
        var file = <object instanceof File or Blob>
        var formData = new window.FormData();
        formData.append('file', file);

        var opts = {
            method: "POST",
            url: <some api url>,
            body: formData,
        };

        xhr(opts,function...

Ahh, you're right. It was something else completely that was causing issues. Thanks for confirming that it works!
