Class console
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
控制台
借助此类,如果脚本与标准 Cloud 项目相关联,开发者可以将数据写入执行日志和 Google Cloud Logging。
如需完全支持 Cloud Logging 和结构化日志记录,请使用 Logger
。console
方法会将对象序列化为字符串,并且不支持在结构化日志记录 LogEntry
中使用 jsonPayload
。
function measuringExecutionTime() {
const label = "myFunction() time"; // Labels the timing log entry.
console.time(label); // Starts the timer.
try {
myFunction(); // Function to time.
} catch (e) {
// Logs an ERROR message.
console.error("myFunction() yielded an error: " + e);
}
console.timeEnd(label); // Stops the timer, logs execution duration.
}
function myFunction() {
// ...
}

error()
向 Stackdriver Logging 输出空白的 ERROR 级别消息。
将 ERROR 级别消息输出到 Stackdriver Logging。
参数
名称 | 类型 | 说明 |
formatOrObject | Object | 包含零个或多个替换字符串的字符串,或者一个 JavaScript 对象(如果没有其他参数,则将其记录为 JavaScript 对象)。 |
values | Object... | 用于替换消息中的替换字符串的对象。这样一来,您就可以进一步控制输出的格式。 |
info()
向 Stackdriver Logging 输出空白 INFO 级别消息。
将 INFO 级别消息输出到 Stackdriver Logging。
参数
名称 | 类型 | 说明 |
formatOrObject | Object | 包含零个或多个替换字符串的字符串,或者一个 JavaScript 对象(如果没有其他参数,则将其记录为 JavaScript 对象)。 |
values | Object... | 用于替换消息中的替换字符串的对象。这样一来,您就可以进一步控制输出的格式。 |
log()
向 Stackdriver Logging 输出空白的 DEBUG 级别消息。
将 DEBUG 级别消息输出到 Stackdriver Logging。
参数
名称 | 类型 | 说明 |
formatOrObject | Object | 包含零个或多个替换字符串的字符串,或者一个 JavaScript 对象(如果没有其他参数,则将其记录为 JavaScript 对象)。 |
values | Object... | 用于替换消息中的替换字符串的对象。这样一来,您就可以进一步控制输出的格式。 |
time(label)
启动一个计时器,您可以使用该计时器跟踪操作所需的时间。
参数
名称 | 类型 | 说明 |
label | String | 要为新计时器指定的名称。 |
timeEnd(label)
停止之前通过调用 console.time()
启动的计时器。系统会将时长记录到 Stackdriver 中。
参数
名称 | 类型 | 说明 |
label | String | 要停止的计时器的名称。 |
warn()
向 Stackdriver Logging 输出空白的 WARNING 级别消息。
将 WARNING 级别消息输出到 Stackdriver Logging。
参数
名称 | 类型 | 说明 |
formatOrObject | Object | 包含零个或多个替换字符串的字符串,或者一个 JavaScript 对象(如果没有其他参数,则将其记录为 JavaScript 对象)。 |
values | Object... | 用于替换消息中的替换字符串的对象。这样一来,您就可以进一步控制输出的格式。 |
