无法使用 SharePoint 下载 docx 文件

Question

I got the attached img value as response from the SharePoint server but can not write it on the docx file. The file download API using Postman is giving same response and if I save Postman response to docx file then it is saving perfectly but not from Java side. If I write same response to a docx file using Java, the file is corrupted.

I am using this REST API to download the file from Sharepoint:

SiteURL/_api/web/getfilebyserverrelativeurl('relativeURL/Shared Documents/test.docx')/$value

Most likely server is returning the document (docx) as binary ( application/octet-stream ). Your code saves the document's string representation:

        ResponseEntity<String> response = restTemplate.exchange(fileUrl, HttpMethod.GET, request, String.class);
        String responseStrFromSharePoint = response.getBody();

That's why the file could not be decoded by application. Instead save the exact binary (bytes) returned by the server as the following snippet shows:

        ResponseEntity<byte[]> response = restTemplate.exchange(fileUrl, HttpMethod.GET, request, byte[].class);
        byte[] responseStrFromSharePoint = response.getBody();

Other parts of the code seems fine.
