vue中,Upload上传组件el-upload的使用-zip格式,大小不超过10M & store中获取和保存token
index.vue
<el-form :model="form" class="form" ref="ruleForm" :rules="rules" label-width="120px"> <el-form-item label="上传程序包:" prop="fileName"> <el-upload :action="upload.url" :on-success="onSuccess" :on-error="onError" :headers="upload.header" :beforeUpload="beforeUpload"> <el-button type="mini">上传</el-button> zip格式,大小不超过10M </el-upload> </el-form-item> <el-form-item> <el-button type="primary" @click="onSubmit">立即添加</el-button> <el-button @click="backToList">取消</el-button> </el-form-item> </el-form>
<script>import store from '@/store/index';export default { data() { return { upload: { url: `${App.apiConfig.service}/dcp-manage/dcp/compile/manage/service/editor/version/upload`, header: { token: store.state.token }, resData: {} }, form: { nameDesc: '', age:'' }, rules: { nameDesc: [ { required: true, message: '不能为空', trigger: 'blur' } ], fileName: [ { required: true, message: '不能为空', trigger: 'blur' } ] } } }, methods: { beforeUpload(file) { const sizeLimit = file.size / 1024 / 1024 > 10 if (sizeLimit) { this.$message.warning('上传文件大小不能超过 10MB!') } const fileFamart = file.name.split('.')[file.name.split('.').length - 1]; if (fileFamart !== 'zip') { this.$message.warning('必须上传zip格式的文件!') } return !sizeLimit && fileFamart === 'zip' }, onSuccess(data) { this.form = { ...this.form, ...data.data // 把上传文件添加到form中 } this.$message.success('上传成功!'); }, onError() { this.$message.error('上传失败!'); }, // 立即添加 onSubmit() { this.$refs.ruleForm.validate(valid => { // 校验form表单 if (!valid) return false; ajax.post('cs_addVersion', this.form).then(res => { this.$message.success('新增成功!'); this.backToList(); // 新增成功后返回 }, err => { this.$message.error('新增失败!'); }); }); }, // 取消 backToList() { this.$router.back(); } }}
