错误行为

当策略检查失败时，Node.js 默认会抛出错误。 通过在策略清单中定义 “onerror” 字段，可以将错误行为更改为几种可能性之一。 以下值可用于更改行为：

• "exit": 将立即退出进程。 不允许运行任何清理代码。
• "log": 将在发生故障的地方记录错误。
• "throw": 将在失败的地方抛出 JS 错误。 这是默认值。

{
  "onerror": "log",
  "resources": {
    "./app/checked.js": {
      "integrity": "sha384-SggXRQHwCG8g+DktYYzxkXRIkTiEYWBHqev0xnpCxYlqMBufKZHAHQM3/boDaI/0"
    }
  }
}

When a policy check fails, Node.js by default will throw an error. It is possible to change the error behavior to one of a few possibilities by defining an "onerror" field in a policy manifest. The following values are available to change the behavior:

• "exit": will exit the process immediately. No cleanup code will be allowed to run.
• "log": will log the error at the site of the failure.
• "throw": will throw a JS error at the site of the failure. This is the default.

{
  "onerror": "log",
  "resources": {
    "./app/checked.js": {
      "integrity": "sha384-SggXRQHwCG8g+DktYYzxkXRIkTiEYWBHqev0xnpCxYlqMBufKZHAHQM3/boDaI/0"
    }
  }
}
