{"success":true,"filename":"spreadsheet.xlsx","file":[80,75,3,4,20,...(many more)]}

如何使用文件名和字节数组(文件)的内容进行文件下载对话？

UPDATE

所以我发现这一点开始downlaod

var a = window.document.createElement('a');
                    a.href = window.URL.createObjectURL(new Blob(data.file,{ type: 'application/octet-stream' }));
                    a.download = data.filename;

                    // Append anchor to body.
                    document.body.appendChild(a)
                    a.click();

                    // Remove anchor from body
                    document.body.removeChild(a)

到目前为止好

但是我得到的文件被损坏,所以我怀疑我需要编码/解码文件变量？

解决方法

var arr = data.file;
var byteArray = new Uint8Array(arr);
var a = window.document.createElement('a');

a.href = window.URL.createObjectURL(new Blob([byteArray],{ type: 'application/octet-stream' }));
a.download = data.filename;

// Append anchor to body.
document.body.appendChild(a)
a.click();


// Remove anchor from body
document.body.removeChild(a)
