如何实现crash堆栈抓取、crash回调
=====================

可以使用faultLogger.querySelfFaultLog获取故障日志，该方法可以捕获 C++ 程序故障、JS 程序故障和应用程序卡死故障。通过此方法，可以获取故障进程的进程 ID、故障进程的用户 ID、故障类型、日志生成时的秒级时间戳、故障原因、故障模块、故障摘要和故障日志全文。请参考以下示例代码：

import { FaultLogger } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit'

async function getLog() {
  try {
    let value: Array<FaultLogger.FaultLogInfo> = await FaultLogger.query(FaultLogger.FaultType.JS\_CRASH);
    if (value) {
      console.info("value length is " + value.length);
      let len: number = value.length;
      for (let i = 0; i < len; i++) {
        console.info("log: " + i);
        console.info("Log pid: " + value\[i\].pid);
        console.info("Log uid: " + value\[i\].uid);
        console.info("Log type: " + value\[i\].type);
        console.info("Log timestamp: " + value\[i\].timestamp);
        console.info("Log reason: " + value\[i\].reason);
        console.info("Log module: " + value\[i\].module);
        console.info("Log summary: " + value\[i\].summary);
        console.info("Log text: " + value\[i\].fullLog);
      }
    }
  } catch (err) {
    console.error(\`code: ${(err as BusinessError).code}, message: ${(err as BusinessError).message}\`);
  }
}
