插件配置

随着插件功能的增加,可能需要定义一些配置以让用户自定义插件的行为。

AstrBot 提供了”强大“的配置解析和可视化功能。能够让用户在管理面板上直接配置插件,而不需要修改代码。

配置定义

要注册配置,首先需要在您的插件目录下添加一个 _conf_schema.json 的 json 文件。

文件内容是一个 Schema(模式),用于表示配置。Schema 是 json 格式的,例如上图的 Schema 是:

{
  "token": {
    "description": "Bot Token",
    "type": "string",
  },
  "sub_config": {
    "description": "测试嵌套配置",
    "type": "object",
    "hint": "xxxx",
    "items": {
      "name": {
        "description": "testsub",
        "type": "string",
        "hint": "xxxx"
      },
      "id": {
        "description": "testsub",
        "type": "int",
        "hint": "xxxx"
      },
      "time": {
        "description": "testsub",
        "type": "int",
        "hint": "xxxx",
        "default": 123
      }
    }
  }
}
  • type: 此项必填。配置的类型。支持 string, text, int, float, bool, object, list, dict, template_list。当类型为 text 时,将会可视化为一个更大的可拖拽宽高的 textarea 组件,以适应大文本。
  • description: 可选。配置的描述。建议一句话描述配置的行为。
  • hint: 可选。配置的提示信息,表现在上图中右边的问号按钮,当鼠标悬浮在问号按钮上时显示。
  • obvious_hint: 可选。配置的 hint 是否醒目显示。如上图的 token
  • default: 可选。配置的默认值。如果用户没有配置,将使用默认值。int 是 0,float 是 0.0bool 是 Falsestring 是 ""object 是 {}list 是 []。
  • items: 可选。如果配置的类型是 object,需要添加 items 字段。items 的内容是这个配置项的子 Schema。理论上可以无限嵌套,但是不建议过多嵌套。
  • invisible: 可选。配置是否隐藏。默认是 false。如果设置为 true,则不会在管理面板上显示。
  • options: 可选。一个列表,如 "options": ["chat", "agent", "workflow"]。提供下拉列表可选项。
  • editor_mode: 可选。是否启用代码编辑器模式。需要 AstrBot >= v3.5.10, 低于这个版本不会报错,但不会生效。默认是 false。
  • editor_language: 可选。代码编辑器的代码语言,默认为 json
  • editor_theme: 可选。代码编辑器的主题,可选值有 vs-light(默认), vs-dark
  • _special: 可选。用于调用 AstrBot 提供的可视化提供商选取、人格选取、知识库选取等功能,详见下文。

其中,如果启用了代码编辑器,效果如下图所示:

editor_mode

editor_mode_fullscreen

_special 字段仅 v4.0.0 之后可用。目前支持填写 select_provider, select_provider_tts, select_provider_stt, select_persona,用于让用户快速选择用户在 WebUI 上已经配置好的模型提供商、人设等数据。结果均为字符串。以 select_provider 为例,将呈现以下效果:

file 类型的 schema

在 v4.13.0 之后引入,允许插件定义文件上传配置项,引导用户上传插件所需的文件。

{
  "demo_files": {
    "type": "file",
    "description": "Uploaded files for demo",
    "default": [], // 支持多文件上传,默认值为一个空列表
    "file_types": ["pdf", "docx"] // 允许上传的文件类型列表
  }
}

dict 类型的 schema

用于可视化编辑一个 Python 的 dict 类型的配置。如 AstrBot Core 中的自定义请求体参数配置项:

"custom_extra_body": {
  "description": "自定义请求体参数",
  "type": "dict",
  "items": {},
  "hint": "用于在请求时添加额外的参数,如 temperature、top_p、max_tokens 等。",
  "template_schema": { # 可选填写 template schema,当设置之后,用户可以透过 WebUI 快速编辑。
      "temperature": {
          "name": "Temperature",
          "description": "温度参数",
          "hint": "控制输出的随机性,范围通常为 0-2。值越高越随机。",
          "type": "float",
          "default": 0.6,
          "slider": {"min": 0, "max": 2, "step": 0.1},
      },
      "top_p": {
          "name": "Top-p",
          "description": "Top-p 采样",
          "hint": "核采样参数,范围通常为 0-1。控制模型考虑的概率质量。",
          "type": "float",
          "default": 1.0,
          "slider": {"min": 0, "max": 1, "step": 0.01},
      },
      "max_tokens": {
          "name": "Max Tokens",
          "description": "最大令牌数",
          "hint": "生成的最大令牌数。",
          "type": "int",
          "default": 8192,
      },
  },
}

template_list 类型的 schema

Note

v4.10.4 引入。更多信息请查看:#4208

插件开发者可以在_conf_schema中按照以下格式添加模板配置项(有点类似于原有的嵌套配置)

 "field_id": {
  "type": "template_list",
  "description": "Template List Field",
  "templates": {
    "template_1": {
        "name": "Template One",
        "hint":"hint",
        "items": {
          "attr_a": {
            "description": "Attribute A",
            "type": "int",
            "default": 10
          },
          "attr_b": {
            "description": "Attribute B",
            "hint": "This is a boolean attribute",
            "type": "bool",
            "default": true
          }
        }
      },
    "template_2": {
      "name": "Template Two",
      "hint":"hint",
      "items": {
        "attr_c": {
          "description": "Attribute A",
          "type": "int",
          "default": 10
        },
        "attr_d": {
          "description": "Attribute B",
          "hint": "This is a boolean attribute",
          "type": "bool",
          "default": true
        }
      }
    }
  }
}

保存后的 config 为

"field_id": [
    {
        "__template_key": "template_1",
        "attr_a": 10,
        "attr_b": true
    },
    {
        "__template_key": "template_2",
        "attr_c": 10,
        "attr_d": true
    }
]

在插件中使用配置

AstrBot 在载入插件时会检测插件目录下是否有 _conf_schema.json 文件,如果有,会自动解析配置并保存在 data/config/<plugin_name>_config.json 下(依照 Schema 创建的配置文件实体),并在实例化插件类时传入给 __init__()

from astrbot.api import AstrBotConfig

class ConfigPlugin(Star):
    def __init__(self, context: Context, config: AstrBotConfig): # AstrBotConfig 继承自 Dict,拥有字典的所有方法
        super().__init__(context)
        self.config = config
        print(self.config)

        # 支持直接保存配置
        # self.config.save_config() # 保存配置

配置更新

您在发布不同版本更新 Schema 时,AstrBot 会递归检查 Schema 的配置项,自动为缺失的配置项添加默认值、移除不存在的配置项。
