Question

我已经在我的GC帐户中创建了一个BigTable实例，当我尝试使用Google的库连接到它时（这是来自Google文档的示例代码）：

require 'vendor/autoload.php';

use Google\Cloud\Bigtable\BigtableClient;

/** Uncomment and populate these variables in your code */
$project_id = 'my_project_id';
$instance_id = 'table_instance';
$table_id = 'table_name';

// Connect to an existing table with an existing instance.
$dataClient = new BigtableClient([
    'projectId' => $project_id,
]);
$table = $dataClient->table($instance_id, $table_id);
$key = 'r1';
// Read a row from my-table using a row key
$row = $table->readRow($key);

$column_family_id = 'cf1';
$column_id = 'c1';
// Get the Value from the Row, using the column_family_id and column_id

$value = $row[$column_family_id][$column_id][0]['value'];

printf("Row key: %s\nData: %s\n", $key, $value);

我遇到错误：

有帮助吗？

好，我知道了。

对于那些面临相同问题的人：在您的php.ini文件中创建/添加一行： extension=grpc.so

php.ini应该与app.yaml相同目录

使用Google的PHP客户端库连接到BigTable时出错
