本地运行的 Azure Functions -- 无法从 'verbose' 设置日志记录级别控制台充满了垃圾

Question

github 上似乎有很多答案，stackoverflow 上也有一些答案，但它们都不再有效/工作了。我正在尝试开发一个 azure-functions 节点应用程序，并在本地运行它将使控制台充满大量无用的垃圾。我一直在尝试改变函数的日志记录级别，但没有成功，我已将它们添加到我的 function.json 和 host.json 以及 local.settings.json 中，但它们没有任何区别。

大多数地方告诉我将其添加到“host.json”，但 tsling 会在 bat 右侧抛出“host.json 中不允许的属性 x”，尽管如此，我还是忽略它并尝试。

我已经尝试过:

{
  "logger": {
    "categoryFilter": {
      "defaultLevel": "Information",
      "categoryLevels": {
        "Host.Results": "Error",
        "Function": "Error",
        "Host.Aggregator": "Information"
      }
    },
    "aggregator": {
      "batchSize": 1000,
      "flushTimeout": "00:00:30"
    }
  },
  "applicationInsights": {
    "sampling": {
      "isEnabled": true,
      "maxTelemetryItemsPerSecond" : 5
    }
  }
}

也只有“错误”，但没有运气。

有人提到尝试:

{
  "logger": {
    "categoryFilter": {
      "categoryLevels": {
        "Function": "Error"
      }
    }
  }
}

这也没有什么区别。

此外，这是淹没相关日志的无用垃圾的一小部分示例:

@Ian 的解决方案有效，但仍然出现一些轻微的垃圾，例如:

[Azure] [1/14/2020 1:03:47 PM] Restarting host.
[Azure] [1/14/2020 1:03:47 PM] Building host: startup suppressed: 'False', configuration suppressed: 'False', startup operation id: '04179110-ad25-4372-818c-b1c4f4a0e1ca'

[Azure] [1/14/2020 1:03:47 PM]       "default": "None"
[Azure] [1/14/2020 1:03:47 PM]     },
[Azure] [1/14/2020 1:03:47 PM]     "console": {
[Azure] [1/14/2020 1:03:47 PM]       "isEnabled": "false"
[Azure] [1/14/2020 1:03:47 PM]     }
[Azure] [1/14/2020 1:03:47 PM]   }
[Azure] [1/14/2020 1:03:47 PM] }
[Azure] [1/14/2020 1:03:47 PM] Reading functions metadata
[Azure] [1/14/2020 1:03:47 PM] 1 functions found

还有几行。

如果能够变得更瘦就好了，但如果不是的话，那也很好。

您似乎正在将 Azure Functions 1.0 格式的配置文件与 Azure Functions 2.0 主机一起使用。请参阅 AF 2.0 配置文件架构的文档:https://learn.microsoft.com/en-us/azure/azure-functions/functions-host-json#logging
