계속 안되서 이미지 파일만 따로 프로젝트를 만들어서 디버깅 하고있는데, 원래 주소 5006에서 파일 전송 클릭할때마다 5000으로 바껴요..

index.html

<form action="http://localhost:5000/uploader"
    method="POST"
    enctype="multipart/form-data">
    <input type="file" name="file" />
    <input type="submit" />
</form>
<script>function uploading_files(){
    let file = files[0]; //실제 파일
    let image = files[0].name; //파일명
    let desc = $('#input_feed_content').val(); //이미지 밑에 쓴 글
    console.log(image)
    let formData = new FormData();
    formData.append('file_give',file)
    formData.append('image_give',image)
    formData.append('desc_give',desc)
    $.ajax({
        type: 'POST',
        url: '/create_content',
        processData: false,
        contentType: false,
        data: formData,
        success: function (response) {
            if (response['result'] == 'success') {
                alert(response['msg'])
                window.location.href = '/'
            } else {
                alert(response['msg'])
                window.location.reload()
            }
        },
        error: function (err) {
            console.log('error:' + err)
        }
    });
</script>
