自己最近在做一个地图的项目，需要导入excel的相关数据，处理为json之后通过接口发给strapi，网上也查看了许多资料，想借助这个机会也整理一下如何实现该功能

引入工具库

npm install -S  xlsx

导入excel

这里我用的是elementUI的el-upload组件
效果图如下：

<el-upload
        class="upload-demo"
        action=""
        :on-change="handleChange"
        :on-exceed="handleExceed"
        :on-remove="handleRemove"
        :before-remove="beforeRemove"
        :file-list="fileList"
        :limit="2"
        accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel"
        :auto-upload="false">
        <el-button size="small" type="info" title = "只能上传xlsx/xls文件">点击上传</el-button>
</el-upload>

具体每一个参数的作用可以点击上方链接查看

 handleChange(file){
         this.fileList.push(file);
         console.log(file,this.fileList);

         this.importExcel(file.raw);
 },

 beforeRemove(file) {
        return this.$confirm(`确定移除 ${ file.name }？`);
 },

 handleExceed(){
       this.$message({
         type:'warning',
         message:'超出上传数量！'
      })
},

 importExcel(file){
        console.log(file);

        let _this = this;
        // 通过DOM取文件数据
        this.file = file;
        var rABS = false; //是否将文件读取为二进制字符串
        var f = this.file;
        var reader = new FileReader();
        //if (!FileReader.prototype.readAsBinaryString) {
        FileReader.prototype.readAsBinaryString = function(f) {
            var binary = "";
            var rABS = false; //是否将文件读取为二进制字符串
            var pt = this;
            var wb; //读取完成的数据
            var outdata;
            var reader = new FileReader();
            reader.onload = function(e) {
            var bytes = new Uint8Array(reader.result);
            var length = bytes.byteLength;
            for(var i = 0; i < length; i++) {
                binary += String.fromCharCode(bytes[i]);
            }
            var XLSX = require('xlsx');
            if(rABS) {
                wb = XLSX.read(btoa(fixdata(binary)), { //手动转化
                    type: 'base64'
                });
            } else {
                wb = XLSX.read(binary, {
                    type: 'binary'
                });
            }
            outdata = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]);//outdata就是你想要的东西
                this.da = [...outdata]
                let arr = []
                this.da.map(v => {
                    let obj = {}
                    obj.name = v['姓名'];  
                    obj.sex = v['性别'];
              
                    console.log(obj);

                    _this.$axios.post(这里写上传的url,JSON.stringify(obj)).then(res => {
                      console.log(res);
                    })
                   
                })

                console.log(arr); //最终结果，数组形式
            }
            reader.readAsArrayBuffer(f);
        }
        
        if(rABS) {
            reader.readAsArrayBuffer(f);
        } else {
            reader.readAsBinaryString(f);
        }

}
// 其中姓名和性别对应的是excel的列名
