vue项目多列导入

用axios.post传一个数组参数使用：JSON.stringify(this.params)

2                 class="upimg">"img">"file" class="file" name="file" @change="getFile($event)">
3                 "submitForm($event)">submit

10         },
11         methods: {
12             //导入excel获取到内容

15                 //jsondata 存储获取excel json数据
16                 var wb,jsondata,that=this;
17                 var f = event.target.files[0];
18                 var reader = new FileReader();

23                 }
24                 reader.readAsBinaryString(f);
25             },
26             submitForm(event){
27                 event.preventDefault();
28 
29                 let params = new URLSearchParams();
30 
31                 params.append('jsondata', JSON.stringify(this.jsondata));
32 
33                 this.axios.post('url', params).then((ret)=>{
34                     if(ret.status === 200){
35                         this.$router.push(ret.data.requireUrl);
36                     }
37                 })
38             }
39         },
40         mounted(){
41             
42         }
43     }

后端接收

$jsondata = $_POST["jsondata"];

$arr = json_decode($jsondata);//需要json_decode()下再使用
