这个问题只在ie中存在，这个要怎么搞

相关代码

// 这是axios
this.instance.get(file/download/${arg.id},{

                responseType: "arraybuffer"
            })
                .then(({data}) => {
                    let blob = new Blob([data], {type: 'application/vnd.ms-excel'});
                    if (window.navigator.msSaveOrOpenBlob) {
                        console.log('IE浏览器');
                        window.navigator.msSaveOrOpenBlob(blob, arg.name);
                    } else {
                        let objectUrl = URL.createObjectURL(blob); 
                        let link = document.createElement('a');
                        link.style.display = 'none';
                        link.href = objectUrl;
                        link.setAttribute('download', arg.name);
                        document.body.appendChild(link);
                        link.click();
                        console.log('非IE浏览器');
                    }
                })
                .catch(error => {
                    console.log(error);
                })

// 我看网上有说用xhr写试一下，我就用xhr试了一下，结果一样
let xhr = new XMLHttpRequest();

            xhr.open("get", `file/download/${arg.id}`, true);
            xhr.responseType="blob";
            xhr.onload = function () {
                if (this.status === 200) {
                    let blob = new Blob([this.response], {type: 'application/vnd.ms-excel'});
                    if (window.navigator.msSaveOrOpenBlob) {
                        console.log('IE浏览器');
                        window.navigator.msSaveOrOpenBlob(blob, arg.name);
                    } else {
                        let objectUrl = URL.createObjectURL(blob); 
                        let link = document.createElement('a');
                        link.style.display = 'none';
                        link.href = objectUrl;
                        link.setAttribute('download', arg.name);
                        document.body.appendChild(link);
                        link.click();
                        console.log('非IE浏览器');
                    }
                }
            }            xhr.send();
