5.7.5 JSON 包装

为了帮助将 MySQL Shell 与外部工具集成，您可以使用 --json 选项在从命令行启动 MySQL Shell 时控制所有 MySQL Shell 输出的 JSON 包装。 --json 选项仅对其指定的 MySQL Shell 会话生效。

指定 --json、--json=pretty 或 --json=raw 将为该会话启用 JSON 包装。使用 --json=pretty 或不指定任何值时，将生成格式良好的 JSON。使用 --json=raw 时，将生成原始 JSON。

启用 JSON 包装后，将忽略在配置文件或命令行（使用 --result-format 选项或其别名之一）中为 resultFormat MySQL Shell 配置选项指定的任何值。

指定 --json=off 将为该会话禁用 JSON 包装。禁用 JSON 包装或未为该会话请求 JSON 包装时，结果集将以 resultFormat MySQL Shell 配置选项指定的格式正常输出。

示例 5.7 使用格式良好的 JSON 包装 (--json 或 --json=pretty) 的 MySQL Shell 输出

$> echo "select * from world_x.city where countrycode='AUT'" | mysqlsh --json --sql --uri user@localhost:33060
or
$> echo "select * from world_x.city where countrycode='AUT'" | mysqlsh --json=pretty --sql --uri user@localhost:33060
