For parameters with a fixed set of values, please use the spec to look at which values are allowed.\n\nUse the exact parameter names as listed in the spec, do not make up any names or abbreviate the names of parameters.\nIf you get a not found error, ensure that you are using a path that actually exists in the spec.\n", suffix: str = 'Begin!\n\nQuestion: {input}\nThought: I should explore the spec to find the base server url for the API in the servers node.\n{agent_scratchpad}', format_instructions: Optional[str] = None, input_variables: Optional[List[str]] = None, max_iterations: Optional[int] = 15, max_execution_time: Optional[float] = None, early_stopping_method: str = 'force', verbose: bool = False, return_intermediate_steps: bool = False, agent_executor_kwargs: Optional[Dict[str, Any]] = None, **kwargs: Any) AgentExecutor[source]¶
从LLM和工具构建OpenAPI代理。
- 安全提示：在创建OpenAPI代理时，请检查底层工具包的权限
和功能。
例如，如果OpenAPIToolkit的默认实现使用RequestsToolkit，该工具包包含针对任何URL（例如，GET、POST、PATCH、PUT、DELETE）进行任意网络请求的工具，
控制可以提交问题请求的人以及该工具包具有的网络访问权限。
有关更多信息，请参阅 https://python.langchain.ac.cn/docs/security。
