如何通过Django请求中的POST请求从Django表单发送特定数据？

Question

所以我目前正在Django项目中，该项目包含两个提交按钮。表单包含3个字段（联系电话，联系人姓名，消息）和两个按钮（搜索，发送）。发送按钮后单击，我只想发送带有ajax发布请求的contact_number字段和message字段。但是它会发送带有ajax请求的所有字段。您能帮我如何通过ajax发布请求发送特定的字段数据。

ajax脚本当ajax请求时，我仅在数据中添加了3个字段，但是我在发布请求中得到了所有字段。

var KTLoginGeneral = function () {

    // var success= $('#success');
    // var error = $('#fail');
    var handleSignInFormSubmit = function () {
            $('#send_msg_submit').click(function (e) {
                e.preventDefault();
                var btn = $(this);
                var form = $(this).closest('form');
                console.log("send submit");

                        }
                    },
                    error(response, e) {

                             $('#kt_modal_1').on('show.bs.modal', function (event) {
                                  var button = $(event.relatedTarget);// Button that triggered the modal
                                  var recipient = button.data('whatever');// Extract info from data-* attributes
                                  var modal = $(this);
                                  modal.find('.modal-title').text('Search Result');
                                  modal.find('.modal-body input').val(recipient)

                                });
                        } else {
                            console.log("else error");
                            success.hide();
                            error.show();
                            error.text(response['error_msg']);
                            setTimeout(function () {
                                btn.removeClass('kt-spinner kt-spinner--right kt-spinner--sm kt-spinner--light').attr('disabled', false);
                            }, 2000);
                        }
                    },
                    error(response, e) {
                        console.log("error");
                        success.hide();
                        error.show();
                        btn.removeClass('kt-spinner kt-spinner--right kt-spinner--sm kt-spinner--light').attr('disabled', false);
                    }
                });
            });
 };

    // Public Functions
    return {
        // public functions
        init: function () {
            handleSignInFormSubmit();
        }
    };
}();
// Class Initialization
jQuery(document).ready(function () {
    KTLoginGeneral.init();
});

但是当我在视图中打印发布请求时，它包含所有数据

<QueryDict: {'csrfmiddlewaretoken': ['EvwkSZPrJYPTHDqKKG0jpfGq98FjIGsM6P83BQ9MGDOxvf0psum1VBZ3IU71XRwh'], 'number': ['8264056065'], 'search_name': [''], 'message': ['hello']}>

预期输出

<QueryDict {'csrfmiddlewaretoken': ['EvwkSZPrJYPTHDqKKG0jpfGq98FjIGsM6P83BQ9MGDOxvf0psum1VBZ3IU71XRwh'], 'number': ['8264056065'], 'message': ['hello']}>

但我在发帖请求中不需要search_name。

request.POST用于表单编码的内容。对于JSON，您应该直接访问普通主体：

json_object = json.loads（request.body）`
