Give id to your form

把身份证给你的表格。

<form id="frm_upload_image" role="form" method="post" action="http://localhost:3000/api/some_url" enctype="multipart/form-data">
    <input type="file" name="file" id="file">
    <input id="submit" type="submit" class="btn btn-primary" value="Submit">
</form>

after that make following changes in your ajax call

然后在ajax调用中进行以下更改

var form = new FormData($("#frm_upload_image"));
   $.ajax({
        url: $("#frm_upload_image").attr('action'),
        type: "POST",                
        data: form,
        contentType: false,       
        cache: false,             
        processData:false,                                  
        success:function() {    
            console.log('success!')
        },
        error: function (a, b, c) {
            console.log(a)
            console.log(b)
            console.log(c)
        }
      });
});
