export导出方法
1、接口返回文档流导出
// 通用下载方法
export function download(url, params, filename, ContentType = 'application/json;charset=utf-8') {
return service.post(url, params, {
// transformRequest: [(params) => {
// return tansParams(params)
// }],
headers: {
'Content-Type': ContentType
},
responseType: 'blob'
}).then((data) => {
const content = data
const blob = new Blob([content])
if ('download' in document.createElement('a')) {
const elink = document.createElement('a')
elink.download = filename
elink.style.display = 'none'
elink.href = URL.createObjectURL(blob)
document.body.appendChild(elink)
elink.click()
URL.revokeObjectURL(elink.href)
document.body.removeChild(elink)
} else {
navigator.msSaveBlob(blob, filename)
}
}).catch((r) => {
})
}
import { download} from '@/utils/request'
// 全局方法挂载
Vue.prototype.download = download
exportData() {
this.download(
"/admin/mnbm/export", // 下载接口地址
{}, // 接口传参
`netbanking_processor_${new Date().getTime()}.xlsx` // 下载文件名称
);
},
2、接口返回数据导出

// 对数据进行处理
formatJson(filterVal, jsonData) {
