element-ui+vue上传图片和评论现成完整html页面

其他更多具体完整项目源码可以私聊我，需要付一点点费用哟~

主要部分的代码讲解

上传图片

首先是先通过el标签中的el-upload标签进行图片的上传，然后发送了一条/common/upload请求到服务端进行图片的上传。而on-success进行监听，上传成功后调用函数，将图片的url地址传到form表单中进行回显

上传成功后调用的函数，将返回的数据传到ruleForm中的image

对照片格式进行检验

上传评论

此处使用的还是el的标签el-input，通过v-model与form表单进行绑定，将数据保存在表单中

当操作完成的时候点击保存按钮触发submitForm函数

这个函数的操作是将ruleForm表单的数据保存到params中，然后将表单参数封装发送请求

发送post请求
