django ajax发送post请求的两种方法，具体内容如下所述：

第一种：将csrf_token放在from表单里


 <script>
    function add_competion_goods() {
      $.ajax({
        url: "{% url 'add_competition_goods' %}",
        type: "POST",
        dataType: "json",
        data: $('#add_competition_goods_from').serialize(),//直接将from表单打包
        success: function () {
          $('#add_competition_modal').modal('hide');
          alert('secces')
        }
      })
    }
  </script>

第二种：发送前添加头部信息


<script>
    function submit_read_save_order_data() {
      var excel_file = document.getElementById("order_excel").files;
      var excel_file_size = excel_file[0]['size'];
      console.log(excel_file_size);
      if (excel_file_size > 0 & excel_file_size < 60000000) {
        alert("已开始上传");
        $('button#upload_data').attr('disabled', 'disabled');
        {#console.log(excel_file_size);#}
        var fd = new FormData();
        fd.append('excels', excel_file[0]);
        $.ajax({
            url: "{%url 'read_save_order_data' %}",
            type: "POST",
            dataType: "json",
            data: fd,
            processData: false,// tell jQuery not to process the data
            contentType: false,// tell jQuery not to set contentType
            beforeSend: function (xhr, setting) {
              xhr.setRequestHeader("X-CSRFToken", "{{ csrf_token }}")
            },
            success: function (msg) {
              alert(msg)
            },
            error: function (msg) {
              alert(msg)
             }
          }
        )
      } else {
        alert("文件为空，或大小超出60M，请检查")
      }
    }
  </script>
