WebUploader.js 上传的几种情况

最近的项目中用到webUploader的地方比较多，总结了几种图片上传的情况。

必要的引用

　　第一，只上传缩略图

页面html

                @if (Model==null||string.IsNullOrEmpty(Model.Cover))
                {
                    
                }
                else
                {
                    
                }
                @Html.HiddenFor(m=>m.Cover)
                

                    
                    

                        
选择图片
                    
                
            

　　js代码

var ratio = window.devicePixelRatio || 1,
  // 缩略图大小
  thumbnailWidth = 240 * ratio,
  thumbnailHeight = 240 * ratio;
        var uploader = WebUploader.create({
            swf: '/Scripts/webuploader-0.1.5/js/Uploader.swf',
            pick: '#picker',
            resize: false,
            accept: {
                title: 'Images',
                extensions: 'gif,jpg,jpeg,bmp,png',
                mimeTypes: 'image/jpg,image/jpeg,image/png'
            },
            thumb: {
                width: 120,
                height: 120,
                quality: 70,
                allowMagnify: true,
                crop: true,
                type: 'image/jpeg'
            },
            method: "POST"
        });
        uploader.on("fileQueued", function (file) {
            uploader.makeThumb(file, function (error, ret) {
                if (error) {
                    alert('预览错误')
                } else {
                    $("#img").attr("src", ret)
                    $("#Cover").val(ret)
                    uploader.reset();
                }
            }, thumbnailWidth, thumbnailHeight);
        })

　　服务端action 在保存方法中直接保存路径

public JsonResult College_Save(XX0301Model.Base model)
        {
            if (!string.IsNullOrWhiteSpace(model.Cover))
            {
                var array = model.Cover.Split(',');
                if (array.Length > 1)
                {
                    var image = array[1];

                    var arr = Convert.FromBase64String(image);
                    MemoryStream ms = new MemoryStream(arr);
                    Bitmap bmp = new Bitmap(ms);

                    var path = Server.MapPath("/Upload/College/");


                    if (!System.IO.Directory.Exists(path))
                        System.IO.Directory.CreateDirectory(path);
                    var fileName = Guid.NewGuid() + ".jpg";
                    bmp.Save(path + fileName, System.Drawing.Imaging.ImageFormat.Jpeg);
                    ms.Close();
                    model.Cover = fileName;
                }
            }
            return IData.XX0301.Save(model).ToJson();
        }

　　第二，上传缩略图和原图

界面html代码

                        @if (Model == null)
                        {
                            "~/Images/blankimg.jpg" width="120" height="120" id="img" />

                        }
                        else
                        {
                            "~/Upload/Campus/@Model.ThumbUrl" width="120" height="120" id="img" />
                        }
                        @Html.HiddenFor(m => m.ID)
                        @Html.HiddenFor(m=>m.ImgUrl)
                        @Html.HiddenFor(m=>m.ThumbUrl)
                        
"uploader" class="wu-example" style="margin-top:10px">
                            
                            
class="btns">
                                
"picker">选择图片
                            
                        
                    

js代码

var ratio = window.devicePixelRatio || 1,
     // 缩略图大小
     thumbnailWidth = 250 * ratio,
     thumbnailHeight = 250 * ratio;
        var uploader = WebUploader.create({
            swf: '/Scripts/webuploader-0.1.5/js/Uploader.swf',
            server: '@Url.Action("CampusUpload")',
            pick: '#picker',
            resize: false,
            auto: true,
            fileSingleSizeLimit: 2 * 1024 * 1024, //1M
            accept: {
                title: 'Images',
                extensions: 'gif,jpg,jpeg,bmp,png',
                mimeTypes: 'image/jpg,image/jpeg,image/png'
            },
            thumb: {
                width: 250,
                height: 250,
                quality: 70,
                allowMagnify: true,
                crop: true,
                type: 'image/jpeg'
            },
            method: "POST"
        });
        uploader.on("uploadStart", function (file) {
            Art.waitPanel.showWait("正在上传文件", 99999);
        })
        uploader.on("error", function (type) {
            Art.waitPanel.closeWait()
            if (type == "Q_TYPE_DENIED") {
                top.$.messager.alert("系统提示", "请上传JPG、PNG格式文件", "error");
            } else if (type == "F_EXCEED_SIZE") {
                top.$.messager.alert("系统提示", "文件大小不能超过1M", "error");
            }
        });
        uploader.on("uploadSuccess", function (file, response) {
            Art.waitPanel.closeWait()
            var data = response
            if (data.flag) {
                uploader.makeThumb(file, function (error, ret) {
                    if (error) {
                        top.$.messager.alert("系统提示", "预览错误","error")
                    } else {
                        Art.waitPanel.showWait("正在生成缩略图", 99999);
                        $.post("@Url.Action("Campus_MakeThumb")", { image: ret }, function (result) {
                            if (result.flag) {
                                $("#img").attr("src", ret)
                                $("#ImgUrl").val(data.data)
                                $("#ThumbUrl").val(result.data)
                                uploader.reset();
                            } else {
                                top.$.messager.alert("系统提示", result.msg, "error")
                            }
                            Art.waitPanel.closeWait()
                        })

                    }
                }, thumbnailWidth, thumbnailHeight);
            } else {
                top.$.messager.alert("系统提示", data.msg, "error")
            }
        })

服务端保存原图，缩略图的代码

public JsonResult CampusUpload()
        {
            var file = Request.Files[0];
            if (file == null)
                return ResultEx.Init(false, "读取图片失败！").ToJson();

            var fileName = file.FileName;
            var fix = fileName.Substring(fileName.LastIndexOf('.') + 1);
            var fixList = new string[] { "jpg", "jpeg", "png", "gif" };
            if (!fixList.Contains(fix))
                return ResultEx.Init(false, "上传的图片格式不正确！").ToJson();
            var maxSize = 1024 * 1024 * 2; //2M
            if (file.ContentLength >= maxSize)
                return ResultEx.Init(false, "上传的图片大小不得大于2M！").ToJson();

            var nFileName = Guid.NewGuid() + "." + fix;
            var path = Server.MapPath("/Upload/Campus/");
            if (!System.IO.Directory.Exists(path))
                System.IO.Directory.CreateDirectory(path);
            file.SaveAs(path + nFileName);
            return ResultEx.Init(true, "", nFileName).ToJson();
        }

        public JsonResult Campus_MakeThumb(string image)
        {
            try
            {
                image = image.Split(',')[1];

                var arr = Convert.FromBase64String(image);
                MemoryStream ms = new MemoryStream(arr);
                Bitmap bmp = new Bitmap(ms);

                var path = Server.MapPath("/Upload/Campus/");


                if (!System.IO.Directory.Exists(path))
                    System.IO.Directory.CreateDirectory(path);
                var fileName = Guid.NewGuid() + ".jpg";
                bmp.Save(path + fileName, System.Drawing.Imaging.ImageFormat.Jpeg);
                ms.Close();
                return ResultEx.Init(true, "", fileName).ToJson();
            }
            catch (Exception ex)
            {
                return ResultEx.Init(ex).ToJson();
            }
        }

    第三，上传url带参数，并且在上传之前做数据校验

html页面

"2" rowspan="6" align="center">

                    @{
                        var path = "/Upload/STUDENT/";
                        var fileName = (Model != null && !string.IsNullOrWhiteSpace(Model.KSH) ? Model.KSH : "nonePhoto");
                        path = path + fileName + ".jpg";
                    }
                    "200" height="250" src="@path" id="img_ZP" />
                    
"uploader" class="wu-example" style="margin-top:10px">
                        
                        
class="btns">
                            
"picker">选择图片
                        
                    
                

js代码

var uploader = WebUploader.create({
            swf: '/Scripts/webuploader-0.1.5/js/Uploader.swf',
            server: '/MCenter/Student/Student_PicUpload',
            pick: '#picker',
            resize: false,
            auto: true,
            fileSingleSizeLimit: 1 * 1024 * 1024, //1M
            accept: {
                title: 'Images',
                extensions: 'gif,jpg,jpeg,bmp,png',
                mimeTypes: 'image/jpg,image/jpeg,image/png'
            },
            method: "POST"
        });
        
        uploader.on("uploadStart", function (file) {
            Art.waitPanel.showWait("正在上传文件", 99999);
        })
        uploader.on('beforeFileQueued', function (file) {
            var KSH = $("#KSH").textbox('getValue');
            if (!KSH || KSH == null || KSH == "") {
                top.$.messager.alert("系统提示", "请填写考生号后再上传图片！")
                return false;
            }
            uploader.options.formData = { KSH: KSH };
        });
        uploader.on("error", function (type) {
            Art.waitPanel.closeWait()
            if (type == "Q_TYPE_DENIED") {
                top.$.messager.alert("系统提示", "请上传JPG、PNG格式文件", "error");
            } else if (type == "F_EXCEED_SIZE") {
                top.$.messager.alert("系统提示", "文件大小不能超过1M", "error");
            }
        });
        uploader.on("uploadSuccess", function (file, response) {
            Art.waitPanel.closeWait()
            var data = response
            if (data.flag) {
                $("#img_ZP").attr("src", "/Upload/Student/" + data.data)
                uploader.reset();
            } else {
                top.$.messager.alert("系统提示", data.msg, "error")
            }
        })

服务端代码上传原图

public JsonResult Student_PicUpload(string KSH)
        {
            var file = Request.Files[0];
            if (file == null)
                return ResultEx.Init(false, "读取图片失败！").ToJson();

            var fileName = file.FileName;
            var fix = fileName.Substring(fileName.LastIndexOf('.') + 1);
            var fixList = new string[] { "jpg", "jpeg", "png", "gif" };
            if (!fixList.Contains(fix))
                return ResultEx.Init(false, "上传的图片格式不正确！").ToJson();
            var maxSize = 1024 * 1024 * 1; //1M
            if (file.ContentLength >= maxSize)
                return ResultEx.Init(false, "上传的图片大小不得大于1M！").ToJson();

            var path = Server.MapPath("/Upload/Student/");
            if (!System.IO.Directory.Exists(path))
                System.IO.Directory.CreateDirectory(path);
            file.SaveAs(path + KSH + ".jpg");

            return ResultEx.Init(true, "",  KSH + ".jpg").ToJson();
        }

    第四，根据官网上的demo的多图队列上传

引用

"~/lib/webuploader/0.1.5/webuploader.css" rel="stylesheet" />
"~/lib/webuploader/0.1.5/demo.css" rel="stylesheet" />

官方的demo需要引用对应的demo.css

js代码

后台上传和使用CodeCarvings生成缩略图和水印的代码

需要使用nuget安装CodeCarvings.Piczard

public JsonResult Pics_Upload(int houseId,HttpPostedFileBase file)
        {
            string md5 = CommonHelper.CalcMD5(file.InputStream);
            string ext = Path.GetExtension(file.FileName);
            string path = "/upload/" + DateTime.Now.ToString("yyyy/MM/dd") + "/" + md5 + ext;// /upload/2017/07/07/afadsfa.jpg
            string thumbPath = "/upload/" + DateTime.Now.ToString("yyyy/MM/dd") + "/" + md5 + "_thumb" + ext;
            string fullPath = HttpContext.Server.MapPath("~" + path);//d://22/upload/2017/07/07/afadsfa.jpg
            string thumbFullPath = HttpContext.Server.MapPath("~" + thumbPath);
            new FileInfo(fullPath).Directory.Create();//尝试创建可能不存在的文件夹

            file.InputStream.Position = 0;//指针复位
            //file.SaveAs(fullPath);//SaveAs("d:/1.jpg");
            //缩略图
            ImageProcessingJob jobThumb = new ImageProcessingJob();
            jobThumb.Filters.Add(new FixedResizeConstraint(200, 200));//缩略图尺寸200*200
            jobThumb.SaveProcessedImageToFileSystem(file.InputStream, thumbFullPath);

            file.InputStream.Position = 0;//指针复位

            //水印
            ImageWatermark imgWatermark =
                new ImageWatermark(HttpContext.Server.MapPath("~/images/watermark.jpg"));
            imgWatermark.ContentAlignment = System.Drawing.ContentAlignment.BottomRight;//水印位置
            imgWatermark.Alpha = 50;//透明度，需要水印图片是背景透明的png图片
            ImageProcessingJob jobNormal = new ImageProcessingJob();
            jobNormal.Filters.Add(imgWatermark);//添加水印
            jobNormal.Filters.Add(new FixedResizeConstraint(600, 600));
            jobNormal.SaveProcessedImageToFileSystem(file.InputStream, fullPath);

            HouseSrv.AddNewHousePic(new HousePicDTO { HouseId = houseId, Url = path, ThumbUrl = thumbPath });

            CreateStaticPage(houseId);//上传了新图片或者删除图片都要重新生成html页面

            return Json(AjaxResult.Init(true));
        }
