使用 Google 索引 API 时出现 403 错误

Question

我正在尝试通过 Google 索引 API 发送 POST 请求，但一直收到 HTTP 错误 403（禁止访问）。

我的代码如下：

              require_once '../google-api-php-client-2.2.2/vendor/autoload.php';
              $client = new Google_Client();
              $client->setDeveloperKey('xxxxxxxxxxxxxx');
              $client->setAuthConfig('xxxxxxxxxxxxx.json');
              $client->addScope('https://www.googleapis.com/auth/indexing');
              $httpClient = $client->authorize();
              $endpoint = 'https://indexing.googleapis.com/v3/urlNotifications:publish?key=xxxxxxxxxx';
              $content = "{
                  \"url\": \"https://www.example.com/whatever.html\",
                  \"type\": \"URL_UPDATED\"
              }";
              $response = $httpClient->post($endpoint, [ 'body' => $content ]);
              $status_code = $response->getStatusCode();
              die('I am done...: ' . $status_code);

我明白 "Forbidden" 的意思，但我不明白为什么我会收到错误消息。我已按照设置说明进行操作。我已经设置了 API 键。我什至在开始时没有限制地设置它（当然我稍后会限制它），我已经设置了服务帐户密钥，json 文件存在于我调用它的地方（没有它，我得到一个 401错误，不是 403）并查看使用 API 密钥的帮助，我正确地传递了密钥。

我错过了什么？

Answer 1

如果您收到 403 错误，您很可能只需要在 Google Search Console 中添加您作为所有者使用的服务帐户。

您可以找到说明和/或信息here

Answer 2

首先启用 API。可能是以下错误帮助：

“错误”：{ “代码”：403， "message": "Indexing API has not been used in project xxxxxxxxxx before or it is disabled. 通过访问 https://console.developers.google.com/apis/api/indexing.googleapis.com/overview?project=XXXXXXXXX 启用它然后重试。如果你最近启用了这个 API，请稍等将操作传播到我们的系统并重试的分钟数。",
