The problem of $.ajax between axios and jquery

I submit the form data through the $.ajax method of jquey. The backend can receive it normally, but not with axios.post.
is added through new FormData append. Why can"t axiosy? the channel is axios.post submission formData requires special configuration

$.ajax ({

)

      type:"post",
      url:"http:// ",
      dataType: "json",
      cache: false,
      data: formData,
      processData: false,
      contentType: false,
      success:function(e){
          console.log(e)
      },
      error: function(e) {
        console.log(e)
      }
