Bases: BaseToolkit

PlayWright浏览器工具包。

安全提示 : 该工具包提供了控制Web浏览器的代码。

如果将此工具包暴露给最终用户，请谨慎。该工具包中的工具能够导航到任意网页，点击任意元素，并从网页中提取任意文本和超链接。

具体来说，默认情况下，该工具包允许导航到：

  • 任何URL（包括任何内部网络URL）

  • 以及本地文件

如果暴露给最终用户，请考虑限制对托管代理的服务器的网络访问；此外，建议创建一个具有限制可导航到的URL的args_schema的自定义NavigationTool（例如，仅允许导航到以特定前缀开头的URL）。

请记住，将权限范围限制为应用程序所需的最低权限。如果默认工具选择不适用于应用程序，请考虑创建一个具有适当工具的自定义工具包。

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

param async_browser: Optional['AsyncBrowser'] = None
param sync_browser: Optional['SyncBrowser'] = None
classmethod construct(_fields_set: Optional[SetStr] = None, **values: Any) → Model

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Parameters

  • _fields_set (Optional[SetStr]) –

  • values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) → Model

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters

  • include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

  • exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

  • update (Optional[DictStrAny]) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

  • deep (bool) – set to True to make a deep copy of the model

  • self (Model) –

Returns

new model instance

Return type

Model

dict(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, by_alias: bool = False, skip_defaults: Optional[bool] = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) → DictStrAny

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters
