Microsoft Graph Drive search - microsoft-graph-api

Question

I'm attempting to modify the node.js Quick Start example to produce a list of the user's excel documents, but I'm running into issues.
This query works (returns a non-empty result) in the Graph Explorer:
https://graph.microsoft.com/v1.0/me/drive/root/search(q='.xlsx')?select=name,id,webUrl
I have tried a few ways to reproduce it in graphHelpers.js.
This query returns an empty result:
function getExcelDocs(accessToken, callback) {
// Get list of excel docs in the user's onedrive
request
.get("https://graph.microsoft.com/v1.0/me/drive/root/search(q='.xlsx')?select=name,id,webUrl")
.set('Authorization', 'Bearer ' + accessToken)
.end((err, res) => {
// Returns 200 OK and the search result in the body.
callback(err, res);
});
}
If I substitute the search URL with the drive children query, I get back a non-empty set of documents.
.get('https://graph.microsoft.com/v1.0/me/drive/root/children')
Is there a problem with how I'm formatting the query url?

Answer 1

The parens in the URI are causing the problem here. The content within those parens represents the body of the request. The underlying library that is processing this request (SuperAgent) doesn't seem to like them going directly into the URI.
I believe you can fix this by providing the URL components separately:
request
.get("https://graph.microsoft.com/v1.0/me/drive/root/search", "q='.xlsx'")
.query({ select: 'name,id,webUrl'})
.set('Authorization', 'Bearer ' + accessToken)
.end((err, res) => {
// Returns 200 OK and the search result in the body.
callback(err, res);
});
Alternatively, this might also work:
request
.get("https://graph.microsoft.com/v1.0/me/drive/root/search")
.query({ select: 'name,id,webUrl'})
.send("q='.xlsx'")
.set('Authorization', 'Bearer ' + accessToken)
.end((err, res) => {
// Returns 200 OK and the search result in the body.
callback(err, res);
});
