之后我確實上傳了文件，我將它們的數據保存在 mongo 中，但是如果我處理一個文件，它就可以工作，但是 loop/forEach/map/for 無論如何都不工作文件循環 await Promise.all(files.map(async (file) => { let url= await uploadFileAndSave(req, file); await saveFileDB(file,url); } ))上傳文件功能承諾 return new Promise(async (resolve, reject) => { let pathDir = req.params.uId + "/"; let typeFolder = getTypeFolder(file.name); console.log("type", typeFolder); if (typeFolder) { pathDir += req.body.app ? req.body.app + "/" : ""; pathDir += req.body.appId ? req.body.appId + "/" : ""; pathDir += typeFolder + "/"; currentPath = path.join(__dirname, "../uploads/", pathDir, Date.now() + "__" + file.name) console.log("currentPath", currentPath); file.mv(currentPath).then(async () => { console.log("sAAaved!!!", file.name); resolve(currentPath) }) } })}保存數據庫功能saveFileDB = async (file, pathUrl) => { return new Promise(async(resolve, reject) => { let name = pathUrl.slice(pathUrl.lastIndexOf('/') + 1, pathUrl.length) let newFile = new fileModel({ name, url: pathUrl, dateCreated: Date.now(), size: file.size / 1024 / 1024, icon: iconsClasses[file.name.split(".")[1]], delete: false, }); // console.log("newFile",newFile); try { let result = await newFile.save(); console.log("save in db", result); } catch (err) { console.log(err); res.send(err); } newFile.save((err, fileSaved) => { if (err){ console.log("err",err); reject(err)} console.log('fileSaved',fileSaved); resolve(fileSaved) }); })}
循環多個等待或承諾
莫回無
