Cloud Code JavaScript 脚本

JavaScript

module.exports = async ({ params, context, logger }) => {    logger.info("script executing", {"example.someString": "frog blast the vent core!"});    logger.warning("this is a serious warning that the cheese is about to run out.");    logger.error("out of cheese :(", {"example.foo": 42}, {"example.bar": 7});};

• info(message, ...logAttributes)

• warning(message, ...logAttributes)

• error(message, ...logAttributes)

• fatal(message, ...logAttributes)

限制

• 每个日志属性必须是具有单个键/值对的对象。
• 该值必须是非空原语值（允许使用 false 布尔值）。
