上傳圖片以及文檔

tempFilePaths 為選擇圖片res 里面的其中一個對象
注意：uniapp 上傳圖片不能上傳選中的File 文件（tempFiles這個數(shù)組的東西不能夠上傳） 要上傳（tempFilePaths）讀取圖片后數(shù)組的 此數(shù)組可以用來瀏覽，上傳
選擇圖片加上傳圖片代碼

*多圖上傳注意 files 數(shù)組 對象不能直接傳 tempFilePaths這個數(shù)組 必須要更改

 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; }

Node后端

1. npm install multer
2. npm i express

var express = require("express"); //Express框架 const multer = require("multer"); // multer中間件上傳圖片 接收文件post數(shù)據(jù) // 設(shè)置文件上傳的地方 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 }); //存放上傳的文件 app.use(multerObj.any()); // 存放所有的類型文件 //設(shè)置跨域訪問 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" ); //自定義請求頭 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") { // 攔截請求 return res.send(); } next(); }); app.listen(COMPort, (err: Error) => { if (err) { console.log('啟動錯誤', err) } console.table({ 端口: COMPort, IP: systemOs.IP(), 服務(wù)地址: `http://${systemOs.IP()}:${COMPort}/Mailbox`, 靜態(tài)資源: `IP端口地址加上文件名`, 描述: `Node服務(wù)已啟動成功`, "swagger-ui": `http://${systemOs.IP()}:${COMPort}/api (ts代碼轉(zhuǎn)為js代碼可以正常使用)`, }); // 掛載自定義中間件 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, "上傳成功"); } );
