跨过后台，前端直接上传文件到oss存储

vue代码：

<script>import { uploadOSS } from '@/api/oss'export default {  name: 'ComUpload',  props: {    isFile: {      type: Boolean,      default: () => {        return false      }    }  },  data() {    return {      imageUrl: '',      fileList: [        // {name:'', url: ''}      ]    }  },  methods: {    //  上传图片    upload(file) {      console.log('file', file);      uploadOSS(file).then(res => {        console.log('resresresres', res)        // this.imageUrl = res.res.url        // this.fileList[0].name = file.file.name        // this.fileList[0].url = res.url        this.$emit('uploadSuccess', res.res.requestUrls[0])      }).catch(err => {        console.log('err--', err)      })    },    beforeAvatarUpload(file) {      if (this.isFile) {        // const isWord = ['application/pdf', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'application/msword'].includes(file.type)        const isWord = ['application/vnd.openxmlformats-officedocument.wordprocessingml.document',].includes(file.type)        const isLt2M = file.size / 1024 / 1024 < 20        if (!isWord) {          this.$message.error('上传文件只能是 word和pdf 格式!')        }        if (!isLt2M) {          this.$message.error('上传文件大小不能超过 2MB!')        }        return isWord && isLt2M      } else {        const isJPG = ['image/jpeg', 'image/png'].includes(file.type)        const isLt2M = file.size / 1024 / 1024 < 20        if (!isJPG) {          this.$message.error('上传头像图片只能是 JPG 格式!')        }        if (!isLt2M) {          this.$message.error('上传头像图片大小不能超过 2MB!')        }        return isJPG && isLt2M      }    }  }}</script>
