I would like to figure out a way to append blob to FormData without being forced to add an implicit filename.
formData.append('binary_data', blobObj) always creates a default filename for the key binary_data.
I tried the following code, in order to avoid the implicit filename:
formData.append('binary_data', blobObj, null);
But it turned out to create the filename "null", as the request content shows:
...
Content-Disposition: form-data; name="binary_data"; filename="null"
...
Because of the existence of the filename, the PHP backend automatically saves the binary data as a temporary file, and adds the file information to the $_FILES array. I would like to figure out a way to post blob as FormData without being forced to add an implicit filename, so that the PHP backend can directly save the binary data in $_POST['binary_data'] instead of $_FILES['binary_data'].
Any idea? Thanks!
