Gmail API：对 API 的请求示例

Question

我正在尝试使用我的应用程序访问 Gmail API。我应该已经正确地完成了所有设置，并且我正在测试对 API 的请求，具体而言是获取只读消息的请求。

我的代码：

public function gmail_get_messages()
{
    $client = new Google_Client();

    $client->setApplicationName("Gmail API test");
    $client->setDeveloperKey("MY_KEY");
    $client->setClientSecret('MY_CLIENT_SECRET');
    $client->setScopes(array('https://www.googleapis.com/auth/gmail.readonly'));

    // $client->setAccessToken($token);

    $service = new Google_Service_Gmail($client);

    $url = 'https://www.googleapis.com/gmail/v1/users/MY_EMAIL/messages';

    $header = array("Authorization: access_token {MY_ACCESS_TOKEN}");

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');

    $retValue = curl_exec($ch);
    $response = json_decode(curl_exec($ch));
    $ee       = curl_getinfo($ch);
    print_r($ee);

    print_r($retValue);
}

回复：

{ "error": { "errors": [ { "domain": "global", "reason": "authError", "message": "Invalid Credentials", "locationType": "header", "location": "Authorization" } ], "code": 401, "message": "Invalid Credentials" } }

关于令牌的一个要点。我已将访问令牌和刷新令牌作为 json 格式的文件获取，但我不知道如何将它们包含在请求中。

如何正确地将令牌传递给请求？是唯一缺少的东西还是有其他东西？

如果有人可以提供正确请求的示例，我将不胜感激！

我认为你很接近！尝试像这样将访问令牌分配给客户端：

$client = new Google_Client();


$client->setApplicationName('Gmail API test');
$client->setDeveloperKey('MY_KEY');
$client->setClientSecret('MY_CLIENT_SECRET');
$client->SetClientId('MY_CLIENT_ID');
$client->setScopes(array('https://www.googleapis.com/auth/gmail.readonly'));
$client->setAccessToken('{"access_token":"MY_ACCESS_TOKEN",
                          "token_type":"Bearer"‌​,"expires_in":3600,
                          "refresh_token":"MY_REFRESH TOKEN","created":1433329214}');

$service = new Google_Service_Gmail($client);

$messages = $service->users_messages->listUsersMessages('me');
$list = $messages->getMessages();

// Look at the contents of the first message
$message = $list[0];
$parts = $message->getPayload()->getParts();

$body = $parts[0]['body'];
$rawData = $body->data;
$sanitizedData = strtr($rawData,'-_', '+/');
$decodedMessage = base64_decode($sanitizedData);
var_dump($decodedMessage);
