使用el-upload组件上传文件
具体参数说明，如何实现上传、下载、删除等功能
获取文件列表进行file-list格式匹配
代码
<script>
import {
getObj,
addObj,
putObj,
fetchList,
getnoticeId,
delObj
} from ‘@/api/policy/noticeattachment’
import store from ‘@/store’
import {
mapState} from ‘vuex’
export default {
data() {
return {
dataForm: {
id: 0,
noticeId: ‘’,
attachName: ‘’,
attachUrl: ‘’,
},
dataList: [],
fileData: [],
headers: {
‘Authorization’: ‘Bearer ‘ + store.getters.access_token,
},
}
},
methods: {
init(id) {
// console.log(id)
this.dataForm.noticeId = id
//数组每次需要清空
this.fileData.splice(0, this.fileData.length);
this.KaTeX parse error: Expected ‘EOF’, got ‘&’ at position 167: …ken operator”>=&̲gt;</span> <spa…refs[‘dataForm’].resetFields();
if (this.dataForm.noticeId) {
getnoticeId(this.dataForm.noticeId).then(response => {
this.dataList = response.data.data;
this.dataList.forEach(list => {
this.fileData.push({
name: list.attachName,
url: list.attachUrl,
id: list.id //删除时使用
})
})
});
}
});
},
//移除回调
handleRemove(file, fileList) {
let resultArr = this.fileData.filter((item) => {
return item.url === file.url
});
// console.log(resultArr[0])
this.dataForm.id = resultArr[0].id
this.KaTeX parse error: Expected ‘EOF’, got ‘&’ at position 167: …ken operator”>=&̲gt;</span> <spa…message.success(‘删除成功’)
})
},
// 表单提交
dataFormSubmit() {
this.KaTeX parse error: Expected ‘EOF’, got ‘&’ at position 369: …ken operator”>=&̲gt;</span> <spa…message.success(‘修改成功’)
});
} else {
addObj(this.dataForm).then(data => {
this.$message.success(‘添加成功’)
})
}
}
})
}
}
}
</script>
文件展示列表自定义为表格展示
使用的具体参数说明
文件大小展示问题（KB/MB）
文件下载
代码

attachName: ‘’,
attachUrl: ‘’,
attachSize: ‘’,
},
dataList: [],
headers: {
‘Authorization’: ‘Bearer ‘ + store.getters.access_token,

this.dataForm.noticeId = id
this.KaTeX parse error: Expected ‘EOF’, got ‘&’ at position 167: …ken operator”>=&̲gt;</span> <spa…confirm(‘是否确认删除该附件’, ‘提示’, {
confirmButtonText: ‘确定’,
cancelButtonText: ‘取消’,
type: ‘warning’
}).then(function () {
return delObj(id)
}).then(data => {
this.KaTeX parse error: Expected ‘EOF’, got ‘}’ at position 469: …n punctuation”>}̲</span><span cl…message.success(‘添加成功’)
this.getDataList()
})
}
}
}
</script>
<style lang=“scss” scoped=“scoped”>
.down >>> a {
