在我的Ext Js解决方案中,我正在调用一个返回
JSON格式的服务
{"success":true,"filename":"spreadsheet.xlsx","file":[80,75,3,4,20,...(many more)]}
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
解决方法
我将文件转换成Uint8Array,然后将其传递给Blob
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)
