report 诊断报告
稳定性: 2 - 稳定
提供 JSON 格式的诊断摘要，写入文件。
该报告旨在供开发、测试和生产使用，以捕获和保存信息以用于问题确定。 它包括 JavaScript 和原生堆栈跟踪、堆统计、平台信息、资源使用情况等。 启用报告选项后，除了通过 API 调用以编程方式触发之外，还可以在未处理的异常、致命错误和用户信号上触发诊断报告。
下面提供了针对未捕获异常生成的完整示例报告以供参考。

Delivers a JSON-formatted diagnostic summary, written to a file.
The report is intended for development, test, and production use, to capture and preserve information for problem determination. It includes JavaScript and native stack traces, heap statistics, platform information, resource usage etc. With the report option enabled, diagnostic reports can be triggered on unhandled exceptions, fatal errors and user signals, in addition to triggering programmatically through API calls.
A complete example report that was generated on an uncaught exception is provided below for reference.
