推荐答案

当您查看 Cloud Vision 库时，您失败的重点是身份验证，而 Cloud Vision 是 Google Cloud PHP，其中您有 身份验证指南给出了以下建议.

The point you are failing is the Authentication as you are looking at the Cloud Vision library whereas the Cloud Vision is a part of the Google Cloud PHP in which you have the Authentication Guide given which recommends the following.

获得凭据文件后，它可用于创建经过身份验证的客户端.

Once you've obtained your credentials file, it may be used to create an authenticated client.

use Google\Cloud\Core\ServiceBuilder;

// Authenticate using a keyfile path
$cloud = new ServiceBuilder([
    'keyFilePath' => 'path/to/keyfile.json'
]);

// Authenticate using keyfile data
$cloud = new ServiceBuilder([
    'keyFile' => json_decode(file_get_contents('/path/to/keyfile.json'), true)
]);

如果您不希望在您的应用程序代码中嵌入您的身份验证信息，您也可以使用 应用默认凭据.

If you do not wish to embed your authentication information in your application code, you may also make use of Application Default Credentials.

use Google\Cloud\Core\ServiceBuilder;

putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/keyfile.json');

$cloud = new ServiceBuilder();

GOOGLE_APPLICATION_CREDENTIALS 环境变量可能已在您的服务器配置中设置.

The GOOGLE_APPLICATION_CREDENTIALS environment variable may be set in your server configuration.

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

例如:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/[FILE_NAME].json"
