====表结构task_file====
========前端具体到业务表单==========
<el-form-item label="任务附件" prop="taskAttachment">
<el-upload ref="upload" accept=".jpg, .png, .txt, .xlsx, .doc, .docx, .xls, .pdf, .zip, .rar"
:action="upload.url" multiple :http-request="HttpUploadFile" :headers="upload.headers"
:file-list="upload.fileList" :on-remove="handleRemove" :on-success="handleFileSuccess"
:on-change="changeFileList" :data="getfileData()" :auto-upload="false">
<el-button slot="trigger" size="small" type="primary">选取文件</el-button>
</el-upload>
</el-form-item>参数说明===============
data
upload: {
// 是否禁用上传
isUploading: false,
// 设置上传的请求头部
headers: { Authorization: "Bearer " + getToken() },
// 上传的地址
url: process.env.VUE_APP_BASE_API + "/system/taskFile/upload/task",
// 上传的文件列表
fileList: []
},
=============
:action="upload.url" 上传后端接口
==================
multiple 可多选
==================
:http-request="HttpUploadFile" 增加数据
HttpUploadFile(file) {
this.fileData.append('files', file.file); // append增加数据
},
===============
headers="upload.headers" 请求头
=============
:file-list="upload.fileList" 文件列表
=======================
:on-remove="handleRemove" 移除文件操作
handleRemove(file, fileList) {
this.upload.fileList = fileList
this.deleteFilePath.push(file.url)
},
=================
:on-success="handleFileSuccess" 上传成功的操作
//文件上传成功后的钩子函数
handleFileSuccess(response, file, fileList) {
this.upload.isUploading = false;
this.upload.fileList = []
this.$modal.msgSuccess(response.msg);
},
==================
:on-change="changeFileList" 列表长度改变的操作
//fileList长度改变时触发
changeFileList(file, fileList) {
this.upload.fileList = fileList
console.log(this.upload.fileList)
},
======================
:data="getfileData()" 加载数据
getfileData() {
//此处的form是表单中的其它绑定值
return this.form.taskAttachment
},
=======================
:auto-upload="false" 是否自动上传
========================
==修改提交上传文件==
this.submitUpload()
submitUpload() {
//创建FormData对象，用于携带数据传递到后端
this.fileData = new FormData()
this.$refs.upload.submit();
this.fileData.append("data", JSON.stringify(this.form));
this.fileData.append("headers", { Authorization: "Bearer " + getToken() });
this.fileData.append("withCredentials", false)
this.fileData.append("filename", "file");
var i = this.upload.fileList.length
console.log(i)
if (i !== 0) {
//此处执行调用发送请求
uploadFile(this.fileData).then((res) => {
if (res.code === 200) {
this.upload.isUploading = false;
this.upload.fileList = []
// this.$modal.msgSuccess(res.msg);
this.open = false;
this.getList();
}
})
} else {
this.open = false;
this.getList();
//如果没有文件要上传在此处写逻辑
}
},
====下载====

</template>
</el-table-column>
=============
