When laravel uses ajax and formData() to upload files, $request->file() cannot obtain the file information. What should I do?

Question

Using $_FILES can get information, but I want to use laravel's $request to get the information and process it. Does anyone have a solution?

Answer 1

Print $request->headers and see what the Content-Type sent by ajax is. Generally, the Content-Type is wrong.

Answer 2

If the file is cross-domain, the file may not be received. I don’t know what your specific situation is.
