使用GuzzleHttp访问令牌为空

Question

When I try to make a connection to Microsoft Graph with the following code:

$headers = [
    'Authorization: Bearer ' . $this->getAccessToken(),
    'Content-Type: application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false;charset=utf-8',
    'Preference-Applied: odata.track-changes'
];
$response = $this->guzzle->request('GET', 'https://graph.microsoft.com/v1.0/me/calendarview/delta?startdatetime=2017-12-12T00:00:00Z&enddatetime=2020-12-13T00:00:00Z'. ['headers' => $headers], ['debug' => true]);

Which gives me the error: Access token is empty

And the debug gives me this:

• About to connect() to graph.microsoft.com port 443 (#0)
• Trying 40.126.9.112...

Somehow it does work in Postman when I give the same details however like you can see, the code after Bearer is empty. I did check $this->getAccessToken() and it definitely contains the token.

What am I doing wrong here?

Answer 1

        $headers = [
        "Authorization" => "Bearer". $token,
        'Content-Type' => 'application/json'
    ];

$response = $this->guzzle->request('GET', 'https://graph.microsoft.com/v1.0/me/calendarview/delta?startdatetime=2017-12-12T00:00:00Z&enddatetime=2020-12-13T00:00:00Z', ['headers' => $headers], ['debug' => true]);

You had a dot after your URL instead you needed a comma. Also your $ headers array should be format like " $key => $values " relation to be passed in the guzzle request.
