上传图片以及文档

tempFilePaths 为选择图片res 里面的其中一个对象
注意：uniapp 上传图片不能上传选中的File 文件（tempFiles这个数组的东西不能够上传） 要上传（tempFilePaths）读取图片后数组的 此数组可以用来浏览，上传
选择图片加上传图片代码

*多图上传注意 files 数组 对象不能直接传 tempFilePaths这个数组 必须要更改

 let img = []; for (let i = 0; i < tempFilePaths.length; i++) { let obj = new Object(); obj.name = `file` + i; obj.uri = tempFilePaths[i]; img.push(obj); obj = null; }

uniapp 全部代码

 uni.chooseImage({ count: 9, success: (res) => { //上传文件的临时路径 const tempFilePaths = res.tempFilePaths; let img = []; for (let i = 0; i < tempFilePaths.length; i++) { let obj = new Object(); obj.name = `file` + i; obj.uri = tempFilePaths[i]; img.push(obj); obj = null; } const tempFilePaths = res.tempFilePaths; console.log(res); uni.uploadFile({ url:'http://192.168.88.15:8978/Mailbox/'+that.api.pudatefiles, filePath: tempFilePaths[0], files: img , name: 'file', success: (uploadFileRes) => { console.log(uploadFileRes) uni.hideLoading(); if (back.status == "0") { console.log(that.host + back.filepath[0]) that.editorCtx.insertImage({ src: that.host + back.filepath[0], alt: '图像', success: function() {} }) } else { console.log(back.msg); } }, fail: () => { uni.hideLoading(); console.log('图片上传失败，请联系开发'); } }); } })

Node后端

1. npm install multer
2. npm i express

var express = require("express"); //Express框架 const multer = require("multer"); // multer中间件上传图片 接收文件post数据 // 设置文件上传的地方 let storage = multer.diskStorage({ destination: (req: any, file: any, cb: Function) => { cb(null, "./StaticResource/pudate/"); }, filename: (req: any, file: any, cb: Function) => { cb(null, Date.now() + "-" + file.originalname); }, }); let multerObj = multer({ dest: "./StaticResource/pudate/", storage }); //存放上传的文件 app.use(multerObj.any()); // 存放所有的类型文件 //设置跨域访问 app.all("*", (req: any, res: any, next: Function) => { res.header("Access-Control-Allow-Origin", "*"); res.header( "Access-Control-Allow-Headers", "Content-Type, Content-Length, Authorization, Accept, X-Requested-With , yourHeaderFeild" ); res.header( "Access-Control-Allow-Headers", "content-type,SelfSummerHeader,Authorization" ); //自定义请求头 res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS"); res.header("X-Powered-By", "3.2.1"); res.header("Content-Type", "application/json;charset=UTF-8"); res.header("Content-Type", "text/xml"); if (req.method === "OPTIONS" || req.url === "/favicon.ico") { // 拦截请求 return res.send(); } next(); }); app.listen(COMPort, (err: Error) => { if (err) { console.log('启动错误', err) } console.table({ 端口: COMPort, IP: systemOs.IP(), 服务地址: `http://${systemOs.IP()}:${COMPort}/Mailbox`, 静态资源: `IP端口地址加上文件名`, 描述: `Node服务已启动成功`, "swagger-ui": `http://${systemOs.IP()}:${COMPort}/api (ts代码转为js代码可以正常使用)`, }); // 挂载自定义中间件 app.use(middleware_router.bodyData); }); router.all( "/pudatefiles", (req: { files: { path: string }[] }, res: any, next: any) => { let data: Array<string> = []; console.log(req.files); req.files?.forEach((item: any) => { let url = item?.path.replace(/\\/g, "/"); data.push(url?.replace("StaticResource", "")); }); res.sendSuccess(data, "上传成功"); } );
