Php 通过谷歌API发送电子邮件

我正在尝试使用谷歌API发送电子邮件

发送电子邮件控制器看起来像

    public function sendMessage()
    {
        $client = self::getClient();
        $service = new Google_Service_Gmail($client);
        $mailer = $service->users_messages;

        $message = (new \Swift_Message('Here is my subject'))
            ->setFrom('myemailaddress@myserver.com')
            ->setTo(['receiver@someserver.com' => 'Test Name'])
            ->setContentType('text/html')
            ->setCharset('utf-8')
            ->setBody('<h4>Here is my body</h4>');

        $msg_base64 = (new \Swift_Mime_ContentEncoder_Base64ContentEncoder())
            ->encodeString($message->toString());

        $message = new Google_Service_Gmail_Message();
        $message->setRaw($msg_base64);
        $message = $mailer->send('me', $message);
        print_r($message);
    }

当我尝试运行此命令时，我收到错误：

{ "error": { "code": 401, "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.", "errors": [ { "message": "Login Required.", "domain": "global", "reason": "required", "location": "Authorization", "locationType": "header" } ], "status": "UNAUTHENTICATED" } } 

credentials.json

{"web":{
  "client_id":"REDACTED",
  "project_id":"project-44",
  "auth_uri":"https://accounts.google.com/o/oauth2/auth",
  "token_uri":"https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
  "client_secret":"redacted",
  "access_token":"redacted"}}

我的代码有什么问题？当我试图打印$client时，它会显示所需的数据。或者我应该如何登录以正确使用它而不被打断？我以前登录过（几个小时前）。

您似乎错过了获取和/或设置访问令牌或刷新令牌的步骤。在中，是这段代码：

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first
    // time.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken()) {
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        } else {
            // Request authorization from the user.
            $authUrl = $client->createAuthUrl();
            printf("Open the following link in your browser:\n%s\n", $authUrl);
            print 'Enter verification code: ';
            $authCode = trim(fgets(STDIN));

            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken)) {
                throw new Exception(join(', ', $accessToken));
            }
        }
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) {
            mkdir(dirname($tokenPath), 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
}

把它分解一下：

您需要通过将用户发送到授权URL（

$client->createAuthUrl（）

）来请求用户的授权

然后将代码交换为访问令牌（

$client->fetchAccessTokenWithAuthCode（$authCode）

）

然后在您的客户端上设置它（

$client->setAccessToken（$accessToken）

），或者保存它以备将来使用

除了访问令牌之外，您还需要保存返回的刷新令牌，这样就不必每次重新登录（

$client->fetchAccessTokenWithRefreshToken（$refreshToken）

）。如果您已经完成了此过程，那么您的访问令牌可能已过期，您需要使用刷新令牌或重新验证才能再次获得访问权限

如果您开发此应用程序的用户不仅仅是您自己，您可能希望了解我在哪里工作。它们处理获取授权、刷新令牌等过程，同时加密令牌并为每个用户存储令牌。

在哪里设置客户端ID和客户端机密？（）它存储在credentials.json中，我应该在其他地方复制它吗？检查我的问题我已经用凭据更新了它file@RedEclipse不要把你的信用档案贴在任何你认为应该保密的地方。我一直把它们作为例子，但它们被大量修改，以不同的方式感谢你的回答。虽然我以前尝试过，但在STDIN方面出现了PHP错误。我想，如果intead每次都要求代码，那么手动将其设置为=$accessToken=$client->fetchAccessTokenWithAuthCode（“keytoken”）？它运行良好-没有错误，但仍然没有收到任何电子邮件。。。是不是因为我在本地主机上测试它，而不是在提供的域名上（在谷歌API中）？啊，它工作了（需要等待大约10分钟）！嗯，我希望钥匙代币在那之前不会改变。。

        $accessToken = json_decode(file_get_contents($tokenPath), true);
