NETCORE 接收FormData文件数据

在前台页面中传输

 formData.append('guid', this.$data.guid);
 $.ajax({
                    url: '/api/Annex/Annex/UploadAnnex',
                    type: 'Post',
                    contentType: false,
                    processData: false,
                    data: formData,
                    success: function (data) {
                        if (data.Result) {
                            if (data.Data == null) {
                                layer.open({
                                    content: data.Message, btn: '我知道了', shadeClose: false
                                });
                            } else {

                           
                        }
                    },
                    complete: function () {
                        // 关闭遮罩等待层
                        layer.close(loadingIndex);
                    }
                });

contentType: false,
processData: false,
在FormData类型的数据是，这两个配置必须设置

后台controller接收时

public CommonResult UploadAnnex([FromForm(Name = "files")] List<IFormFile> files, [FromForm(Name = "guid")] string guid)

FromForm(Name = "files")来接收file和其他参数
