Google Drive web view link retrieved in Google API explorer, but not in my code-CodePudding

I have code that uploads files to Google Drive and sets the appropriate permissions so that anyone in the domain can read them.

If I use the Google Drive API explorer and enter the Id of the file and enter "webViewLink" in the "fields" textbox, then when I execute the request, I see something like this (actual link obfuscated)...

{
 "webViewLink": "https://drive.google.com/file/d/abcdef123456/view?usp=drivesdk"
}

Entering the link in a private browser window allows me to see the file as expected.

However, if I try to get the link in my C# code...

FilesResource.GetRequest request = _service.Files.Get(fileId);
request.Fields = "webViewLink";
var file = await _service.Files.Get(fileId).ExecuteAsync();

...then the file.WebViewLink property is always blank. Looking at the network tab, it seems is if the same API is being called with the same parameters,

Anyone any ideas? I have double-checked, and I'm using the same Google account in both the API explorer and my code (I know this because otherwise I wouldn't be able to see other files in the drive)

CodePudding user response：

Your C# code sets up a request and sets the Fields on it but then you call the _service.Files.Get(fileId) again so you're ignoring the original request you set up with the additional Fields, therefore it is using the default Fields and not the ones you set up.

Try doing var file = await request.Get(fileId).ExecuteAsync(); so it'll use the Fields set up for that requset.
