本地 Azure Functions 运行 -- 无法从 'verbose' 控制台设置日志记录级别充满垃圾

Question

github 上似乎有大量答案，Whosebug 上也有一些答案，但 none 不再是 valid/work。我正在尝试开发一个 azure-functions 节点应用程序，运行它在本地会用大量无用的垃圾填满控制台。我一直在尝试更改函数的日志记录级别但无济于事，我已将这些都添加到我的 function.json 和 host.json 以及 local.settings.json 但它们没有任何区别.

大多数地方都告诉我将它添加到 'host.json'，但 tsling 抛出 'property x not allowed in host.json' 的正确方法，none尽管如此，我还是忽略了它并尝试了。

我试过：

{
  "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 'Errors'，但运气不好。

有人提到尝试：

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

这也没什么区别。

此外，这里有一小部分无用垃圾淹没了相关日志：

@Ian 的解决方案有效，但仍然会出现一些次要的垃圾，例如：

[Azure] [1/14/2020 1:03:47 PM] Restarting host.

[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。

能够变得更苗条会很好，但如果不是这样也很好。

您似乎在将 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://docs.microsoft.com/en-us/azure/azure-functions/functions-host-json#logging
