mui+h5 做的app，怎么下载并打开blob文件

分类：HTML5+

可以下载blob文件，但是在手机上打不开blob的文件
用下面的方式在浏览器端可以打开，但是在手机端打开失败

                       const oReq = new XMLHttpRequest();  
            oReq.open('GET', fileurl.replace("#",'%23'), true);  
            oReq.responseType = 'arraybuffer';  
            oReq.withCredentials = true;  
            oReq.onload = function () {  
                const arrayBuffer = oReq.response; // Note: not oReq.responseText  
                if (arrayBuffer) {  
                    const byteArray = new Uint8Array(arrayBuffer);  
                    const aLink = document.createElement('a');  
                    const blob = new Blob([byteArray], { type: 'application/pdf' });  
                    let fileName = "审批单.pdf";  

                    aLink.download = fileName;  
                    aLink.href = URL.createObjectURL(blob);  
                    aLink.target = '_blank';  
                    aLink.className="J_notOpenInContainer";  
                    document.body.appendChild(aLink);  
                    console.log(URL.createObjectURL(blob))  
                    aLink.click();  
                }  
            };  
            const form = new FormData();  
            form.append('_scm_token_', window._scm_token_);  
            oReq.send(form);
