~~Diagnostic report~~诊断报告

Diagnostic report诊断报告#

~~Delivers a JSON-formatted diagnostic summary, written to a file.~~提供JSON格式的诊断摘要，并将其写入文件。

~~The report is intended for development, test, and production use, to capture and preserve information for problem determination.~~ 该报告旨在用于开发、测试和生产，以获取和保存信息以确定问题。~~It includes JavaScript and native stack traces, heap statistics, platform information, resource usage etc.~~ 它包括JavaScript和本机堆栈跟踪、堆统计信息、平台信息、资源使用情况等。~~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.~~启用报告选项后，除了通过API调用以编程方式触发外，还可以对未处理的异常、致命错误和用户信号触发诊断报告。

~~A complete example report that was generated on an uncaught exception is provided below for reference.~~下面提供了一个针对未捕获异常生成的完整示例报告供参考。
