<template>
<div class="newWorkForm">
<!--新增通知对话框-->
<el-dialog
title="新增作业"
:before-close="handleClose"
:visible.sync="dialogVisible"
width="50%"
v-loading="loading"
element-loading-text="拼命上传中"
element-loading-spinner="el-icon-loading"
element-loading-background="rgba(0, 0, 0, 0.8)"
>
<el-form
:model="Form"
:rules="rules"
ref="Form"
label-width="100px"
class="demo-ruleForm"
>
<!--文件基础内容-->
<el-form-item label="发布者姓名" prop="uname">
<el-input v-model="Form.uname"></el-input>
</el-form-item>
<el-form-item label="文件备注" prop="name">
<el-input v-model="Form.name"></el-input>
</el-form-item>
<el-form-item label="文件类型" prop="type">
<el-select v-model="Form.type" placeholder="请选择类型">
<el-option label="图片" value="image"></el-option>
<el-option label="视频" value="media"></el-option>

</el-form-item>

<!--文件内容上传区-->
<el-form-item label="选择文件" required>
<el-upload
class="upload-demo"
action="https://jsonplaceholder.typicode.com/posts/"
:auto-upload="false"
:http-request="uploadFile"
ref="upload"
:multiple="false"
list-type="picture"
>
<el-button size="small" type="primary">点击上传</el-button>
</el-upload>
</el-form-item>
</el-form>

<span slot="footer" class="dialog-footer">
<el-button type="primary" @click="submitForm('Form')"
>立即发布</el-button
>
<el-button @click="resetForm('Form')">重置</el-button>
</el-form-item>
</span>
</el-dialog>
</div>
</template>
<script>
export default {
data() {
return {
imgsArr:[],
loading:false,
Form: {
uname:"",
name:"",
type:"",
},
rules: {
uname: [

},
};
},
props: {
dialogVisible: {
type: Boolean,
},
},
inject:["reload"],
methods: {
uploadFile(file){
this.imgsArr.push(file.file);//往一个数组中添加图片数据
},
handleClose() {
this.$emit("cancle");
},
cancle() {
this.$emit("cancle");
},

this.$emit("confirm");
},
submitForm(formName) {

if(this.imgsArr.length>1){
this.$message.error("请不要上传超过一个文件");
return;
}
this.loading=true;
var formdata=new FormData();
this.$refs.upload.submit();
if(this.imgsArr.length>0){
this.imgsArr.forEach((img,index)=>{
formdata.append(`file`,img);//这里用到index++,防止前面添加的图片被后面的覆盖,下面后端代码有讲如何循环这个数组
})
}else{
this.$message.error("请同时附上相应文件");
return;
}
formdata.append("uname",this.Form.uname);
formdata.append("name",this.Form.name);
formdata.append("type",this.Form.type);
formdata.append("courseId",1);
let config = {
headers: {
'Content-Type': 'multipart/form-data'
}
}//设置请求头!
console.log(formdata.getAll("file"));
this.$http.post("/file/addFile",formdata,config).then(res=>{
if(res.data.status==0){
this.loading=false;
this.$message.success("发布成功");
this.reload();
}else{
this.$message.error("系统异常,发布失败!");
this.$emit("cancle");
}
})
} else {
this.$message.error("参数不正确!");
return false;
}
});
},
resetForm(formName) {
this.$refs[formName].resetFields();
},
},
};
</script>
<style lang="less" scoped>
.newWorkForm{

width: 80%;
}
}
</style>

二后端java代码:

怎么开启oss服务?百度一下

@RestController
@RequestMapping(value = "/file")
public class fileController {
public static String ENDPOINT = "..你的endpoint";
public static String ACCESSKEYID = ".....";
public static String ACCESSKEYSECRET = "......";
public static String BUCKETNAME = "....";
@Autowired
fileServer fileServer;

public ListeningExecutorService executorService= MoreExecutors.listeningDecorator(Executors.newCachedThreadPool());

@PostMapping(value = "/addFile")
public ServerResponse addFile(@RequestParam("file") MultipartFile file,@RequestParam("uname")String uname,
@RequestParam("name")String name,@RequestParam("type")String type,@RequestParam("courseId")int courseId) throws Exception {
InputStream stream=file.getInputStream();
String filename=System.currentTimeMillis()+file.getOriginalFilename();
OSSClient client=new OSSClient(ENDPOINT,ACCESSKEYID,ACCESSKEYSECRET);
PutObjectResult result=client.putObject(BUCKETNAME,type+"/"+filename,stream);
client.shutdown();
String url= type+"/"+filename;//这里直接用字符串拼接就能访问oss,但是要先设置公共读
return fileServer.addFile(courseId,uname,url,name, type);
}

//获取文件列表
@GetMapping(value = "/getFileList/{courseId}")
public ServerResponse getFileList(@PathVariable("courseId") int courseId){
return fileServer.getFileList(courseId);
}
}
