[JavaScript知识库]Vue导出表格 调用后端接口

在http.js文件夹中：

export function downFile(url, data, filename) {
    axios.post(url, data, { responseType: 'blob' })
    .then(data => {
      let blob = new Blob([data.data]);
      console.log(data);
      let url = window.URL.createObjectURL(blob);
      let link = document.createElement('a');
      link.style.display = 'none';
      link.href = url;
      link.setAttribute('download', filename);
      document.body.appendChild(link);
      link.click();
      window.URL.revokeObjectURL(url);
      document.body.removeChild(link);
    });
}

导出：
1.import {downFile} from "@/utils/http.js"

2.在method中：

  methods: {
  //导出
    export_but(){
      
      downFile('/XXX/XXXXXXXX', {
        topicSetId: '3',
        userGroupId: '3'//给后端返回值
      }, 'file.xls');
    },
    '/XXX/XXXXXXXX'后端接口
