Vue Tinymce 图片上传 接口对接

TinyMCE提供了图片上传处理函数images_upload_handler, 该函数有三个参数:blobInfo,success callback,failure callback, 分别是图片内容, 一个成功的回调函数以及一个失败的回调函数,具体上传图片代码在上面已经写,这里就不赘述; 需要注意的是,当向后台上传完图片, 我们要调用success函数来用服务器地址替换<image>标签的src属性。
以下是我基于“vue-element-admin”的项目图片上传服务器接口对接方法
src/components/Tinymce/index.vue

这里面主要的几个部分改动
1、支持粘贴图片
写文章插入图片的时候,经常会用到屏幕截图,截图后直接粘贴到编辑器中,是比较方便的。但是默认这个功能并没有开启,需要添加以下配置:
1 | paste_data_images: true , |
2、支持自动上传
1 | automatic_uploads: true , |
3、编写上传处理程序
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | images_upload_handler: (blobInfo, success, failure) => { const formData = new FormData() formData.append( 'file' , blobInfo.blob()) uploadFile(formData).then(res => { if (res.data) { console.log( 'res.data' , res.data) success(res.data) return } failure( '上传失败' ) }). catch (() => { failure( '上传出错' ) }) }, |
这里的 res.data 就是上传到服务器之后的图片地址,我对接的后端接口 response 的内容是JSON结构,类似下面这样:
1 2 3 4 5 | { "code" : 200, "message" : "成功" , "data" : "/ufs/2021/1/17c5a6fd70804ff784ed21b112854b60.png" } |
4、上传图片方法 uploadFile
1 | import { uploadFile } from '@/api/upload.js' |
src/api/upload.js
1 2 3 4 5 6 7 8 9 10 11 12 | import request from '@/utils/request' export function uploadFile(data) { return request({ url: '/api/common/upload' , method: 'post' , headers: { 'Content-Type' : 'multipart/form-data' }, data }) } |
这里比较重要的是 headers 'Content-Type': 'multipart/form-data',只有设置为'multipart/form-data'才能上传文件。
