get请求
export function getPdf(id) {
const InfoRequestDTO = {
consumer: store.getters.QLMConfig.application_id,
language: store.getters.language,
serialNo: uuid.v1(),
tag: id
};

method: 'get',
params:InfoRequestDTO,
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},

}
调用：
daochu(id) {
this.loading = true;
getPdf(id).then(
data => {
this.loading = false;
let blob = new Blob([data], {
type: 'application/vnd.ms-pdf' })
let objectUrl = window.URL.createObjectURL(blob) // 创建URL
let link = document.createElement('a')
link.style.display = 'none'
link.href = objectUrl
link.download = '突出贡献与创新申报表.pdf' // 自定义文件名
document.body.appendChild(link)
link.click() // 下载文件
window.URL.revokeObjectURL(objectUrl) // 释放内存
// const url = window.URL.createObjectURL(new Blob([data], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" }))
// const link = document.createElement('a')
// link.style.display = 'none'
// link.href = url;
// link.setAttribute('download', '突出贡献与创新申报表.pdf')
// document.body.appendChild(link)
// link.click()
// document.body.removeChild(link)
}
)
},
