JavaWeb_(视频网站)_二、用户模块4 基本信息维护(下)

用户传递图片时，通过saveImage()方法，实现传递的是用户头像或者是用户背景

　　修改uploadImage上传图片的请求，添加一个参数，用来判断用户传递的是头像还是背景

@RequestMapping("/uploadImage")
    public String uploadImage(String base64,String type) throws IOException
    {
        
        //System.out.println("我被点击到了！！");
        User user = (User) httpSession.getAttribute("user");
        //System.out.println(base64)可以在表单提交查看后端是否传入该数据
        //base64的数据非常大，输出出来的话是空白
        
        //获得classpath在本地的地址
        String path = "";
        if(type.equals("cover"))
        {
            path = ResourceUtils.getURL("classpath:").getPath()+"static/upload/user/cover";
        }else {
            path = ResourceUtils.getURL("classpath:").getPath()+"static/upload/user/head";
        }
        
        //保存图片
        File file = new File(path);
        if(file.exists())
        {
            file.mkdir();
        }
        //替换数据
        if(base64.indexOf("jpeg")!= -1)
        {
            base64 = base64.replaceFirst("jpeg", "jpg");
        }
        //文件名
        String upName = UUID.randomUUID().toString()+System.currentTimeMillis()+ "." +base64.substring(11,14);
        //将base64中有用的数据保存下来
        String iconBase64 = base64.substring(22);
        //将base64换位字节数据
        byte[] buffer = Base64Coder.decode(iconBase64);
        //用FileOutputStream写文件
        FileOutputStream out = new FileOutputStream(path + "/" +upName);
        out.write(buffer);
        out.close();
        System.out.println(path+"/"+upName);
        //保存到数据库
        if(type.equals("cover")) {
            user.setCoverImage("user/cover/"+upName);
        }else {
            user.setCoverImage("user/head/"+upName);
        }
        
        userService.saveUser(user);
        return "redirect:/findUserProfileSettingsById?id="+user.getId();
    }

　　使用thymeleaf进行图片的回显

th:style="'background: url(http://www.pinzhi365.com/upload/'+${session.user.coverImage}+') no-repeat;'"

　　数据库中user存储图片字段cover_image字段

 　　在user-bar.html中制作头像模块

　　<img src="http://placehold.it/120x110" alt="profile author img">
　　<button class="btn-upload" onclick="document.getElementById('headFile').click()">
　　　　<i class="fa fa-camera"></i>
　　　　<span>Avatar(500*500)</span>
　　</button>
                    
　　<form action="/cropper" method="post" enctype="multipart/form-data">
　　　　<input style="display:none ;" type="text" value="head" name="type">
　　　　<input id="headFile" style="display:none;" name="file" type="file">
　　　　<input id="fileSubmit" style="display:none;" type="submit">
　　</form>

<!-- Cropper -->
    <script type="text/javascript" th:inline="javascript">
        //获得image
        const image = document.getElementById("image");
        var cropper;
        //初始化Cropper
        window.onload = function()
        {
            if([[${type}]] == 'cover'){
                cropper = new Cropper(image,{
                //裁剪框比例
                aspectRatio:1920/350,
                viewMode:2,
                //预览
                preview:".small",
                //关闭双击会改变方式
                toggleDragModeOnDblclick:false,
                //拖拽模式
                dragMove:'move',
                        
                })
            }else{
                cropper = new Cropper(image,{
                //裁剪框比例
                aspectRatio:120/110,
                viewMode:2,
                //预览
                preview:".userHead",
                //关闭双击会改变方式
                toggleDragModeOnDblclick:false,
                //拖拽模式
                dragMove:'move',
            })
            }
            //替换图片
            cropper.replace("http://www.pinzhi365.com/upload/user/temp/"+[[${fileName}]],false);
        }

        //上传文本
        function saveImage()
        {
            
            var width = cropper.getCropBoxData().width;
            var height = cropper.getCropBoxData().height;
            //拿到Bases 64格式为本
            //1920*350
            //120*110
            var base64URL;
            if([[${type}]] == 'cover')
            {
                base64URL = cropper.getCroppedCanvas({1920,height:350}).toDataURL("image/jpeg");
            }
            else
            {
                base64URL = cropper.getCroppedCanvas({600,height:550}).toDataURL("image/jpeg");
            }
            
            
            $("#base64Input").val(base64URL);
            $("#headCoverType").val([[${type}]]);
            $("#uploadImageSubmit").click();
        }
        
    </script>

 　　当用户保存保存，更换头像更换背景后，在user-bar上显示图片的回显

<img th:if="${page} eq 'ProfileSettings'" th:src="|upload/${user.headImage}|" alt="profile author img">

 更新用户，用户数据的回显

　　数据回显流程

　　　　

 在profile-setting.html页面中完成用户信息模块的回显

 　　校验表单数据Email与Username，校验表单邮箱可以使用data-abide novalidate与required="required"

<form method="post"  th:action="@{~/index}" data-abide novalidate>

<input required="required" type="text" name="firstName" th:value="${session.user.firstName}" placeholder="enter your first name..">

 　　用户提交更新表单，发送updateUser请求，UserController.java进行处理请求

@RequestMapping("/updateUser")
    public String updateUser(User user)
    {
        User u = (User) session.getAttribute("user");
        //更新user
        //System.out.println(user);
        u.setFirstName(user.getFirstName());
        u.setLastName(user.getLastName());
        u.setUsername(user.getUsername());
        u.setDescription(user.getDescription());
        
        u.setPassword(user.getPassword());
        
        u.setEmail(user.getEmail());
        u.setWebUrl(user.getWebUrl());
        u.setPhone(user.getPhone());

        u.setDisplayName(user.getDisplayName());
        
        u.setQqLink(user.getQqLink());
        u.setWeixinLink(user.getWeixinLink());

        userService.saveUser(u);
        
        return "redirect:/findUserProfileSettingsById?id="+u.getId();
    }

　　测试：

完成更新用户完善AboutMe页面(profile-abou-me.html)

 <div class="heading">
                                    <i class="fa fa-user"></i>
                                    <h4>Description</h4>
                                </div>
                                <div class="description">

                                    <div class="site profile-margin">

                                    </div>

 　　通过user访问的其他人页面，session.user访问的是自己的页面

th:style="'background: url(http://www.pinzhi365.com/upload/'+${user.coverImage}+') no-repeat;'"

　　解决一些用户资料bug，如果不是自己，不可以查看自己profile-setting

　　在profile.html中解决，非自己用户，不可查看自己的Profile Settings

 　　在profile-setting.html中，非自己用户也不可修改自己的个人资料

    <div th:if="${session.user.id} eq ${user.id}" class="upload-bg">

　　</div>

 　　在user-bar.html中，非自己用户也不可上传自己的个人头像和背景
