Use OSS to upload pictures or attachments in vue projects

There is no difference between uploading pictures and attachments here; the upload process is the same.

1. Create a new oss.js file Encapsulation uses oss (need to install package ali-oss) const OSS = require ('ali-oss') const OSSConfig = {uploadHost:' http://xxxxx.oss-cn-shenzhen.aliyuncs.com', / / OSS upload address ossParams: {region: 'oss-cn-shenzhen', success_action_status:' 200 accessKeyId: 'LTxxxxxxxxxxxxxxxvnkD', accessKeySecret:' J6xxxxxxxxxxxxxxiuvqi, bucket: 'xxxxxxxx-czx',} } function random_string (len) {len = len | | 32 var chars = 'ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678' var maxPos = chars.length var pwd =' 'for (let I = 0) I

{const fileName = `${random_string (6)} _ ${file.name}` let client = new OSS ({region: OSSConfig.ossParams.region, accessKeyId: OSSConfig.ossParams.accessKeyId, accessKeySecret: OSSConfig.ossParams.accessKeySecret, bucket: OSSConfig.ossParams.bucket,}) const res = await client.multipartUpload (fileName File) / / resolve (res) / / or return the following: resolve ({fileUrl: `${OSSConfig.uploadHost} / ${fileName}`, fileName: file.name})} export {uploadOSS} 2, use oss.js in the page

Here is the secondary encapsulation of the upload component of elementUI, which does not use the action of the component to upload pictures and attachments, but uses the oss upload method

Import {getAccessToken, getRefreshToken, getAccessTokenTTL} from "@ / utils/auth"; import {uploadOSS} from'@ / utils/oss';export default {name: "index", data () {return {};}, computed: {userAccountID () {return this.$store.state.user.userAccountID }, uploadProps () {return {/ / action: `${process.env.VUE_APP_BASE_API} / api/file/ upload`, headers: {/ / API may have token: ", Authorization: getAccessToken (),}, data: {},} },}, methods: {handleExceed (file, fileList) {/ / console.log (file, fileList); this.$message.error ('upload failed, limit the number of files to be uploaded!') ;}, handleUpload (file, fileList) {/ / console.log (file, fileList) Var testmsg = file.name.substring (file.name.lastIndexOf ('.) + 1) const extension = testmsg = 'xlsx' | | testmsg =' xls' | | testmsg = 'docx' | | testmsg =' doc' | | testmsg = 'pdf' | | testmsg =' zip' | | testmsg = 'rar' | | testmsg =' ppt' | | testmsg = = 'txt' const isLimit10M = file.size / 1024 / 1024 < 10 var bool = false; if (extension & isLimit10M) {bool = true } else {bool = false;} if (! extension) {this.$message.error ('Please select an attachment file type!') ; return bool;} if (! isLimit10M) {this.$message.error ('upload failed, cannot exceed 10MB') ; return bool;} return bool;}, handleSuccess (res) {/ / console.log (res); if (res) {this.$emit ('fileData', res) this.$message.success ("upload attachment succeeded!") ;}}, handleError (err) {this.$message.error ('upload attachment failed!') ;}, / / upload async fnUploadRequest (options) {try {/ / console.log (options); let file = options.file; / / get file let res = await uploadOSS (file) console.log (res); / / return data this.$emit ("fileData", res); this.$message.success ("upload attachment succeeded!") ;} catch (e) {this.$message.error ('upload attachment failed!') ;},},};:: v-deep. El-upload,.el-upload--picture-card {/ / width: 50px; height: 0px; border: none; line-height: 0; display: block; background: # f5f6fb;}. El-upload {width: 50px;}. Img-cont {width: 50px; height: 24px; background: # f5f6fb; .img-icon {color: # ccc }. Img-text {font-size: 12px; height: 24px; color: # 000;}}

Use encapsulated upload components
