Office加载项JavaScript FileDownload不适用于MAC

Question

We are having an issue in office add-in with Mac. We can't download file from office-add-in on mac. Same add-in working fine with windows platform.

We have constructed as blob type data from our API Response. Same blob type passing into FileSaver.js of SaveAs method. We are using FileSaver.js to saving files on the word office add-ins.

Note : Everything work fine on windows platform. We already have implementation of html download link attribute same as in following link sample but that won't be use due to security concern.

Force download a pdf link using javascript/ajax/jquery

Here are the our sample code.

 var getMessageUrl = "https://test.xxx.xxx/api/xxx/testcontroller/GetTest?id=121212121212"; var oReq = new XMLHttpRequest(); oReq.open("GET", getMessageUrl, true); oReq.responseType = "arraybuffer"; oReq.setRequestHeader('X_ConnectTo', 'X-Author-CRM'); oReq.setRequestHeader('Access-Control-Allow-Origin', '*'); oReq.setRequestHeader('Access-Control-Allow-Methods', 'GET,POST,PUT,DELETE,OPTIONS'); oReq.setRequestHeader('Access-Control-Allow-Headers', 'Authorization, Content-Type,Accept, Origin'); oReq.setRequestHeader('Authorization', 'Bearer XXXXXXXXX-Token-XXXXXXX'); oReq.setRequestHeader('Content-Type', 'application/json; charset=utf-8'); oReq.onload = function (oEvent) { var blob = new Blob([oReq.response], { type: "application/octet-binary" }); saveAs(blob, 'Test1234.docx'); }; oReq.send();

Answer 1

I wonder if the issue is similar to what we found with Script Lab, https://github.com/OfficeDev/script-lab/issues/458 ? If so, it may be a platform bug/limitation, though it would be good to investigate it further. See more in that issue. If you can confirm whether it's the same issue or not, it would be a good first step. Thanks!
