本文详细描述了一个Java项目中如何通过ChatFunctionTest调用OpenAIAPI获取天气信息，涉及参数构建、API调用和结果处理过程。

From the project: https://github.com/HamaWhiteGG/langchain-java

Please refer to the ChatFunctionTest for the complete test code.

1. Core main process

Generates a ChatParameter instance that represents the given class.
Invoke the OpenAI API and return the function name and parameters.
Execute functions through the FunctionExecutor.

2. Step-by-step introduction

2.1 Declare function parameters and response

public record Weather(
        @JsonProperty(required = true)
        @JsonPropertyDescription("The city and state, e.g. San Francisco, CA")
        String location,

        @JsonPropertyDescription("The temperature unit")
        WeatherUnit unit
) {
   
   }


public enum WeatherUnit {
   
   

    CELSIUS,
    FAHRENHEIT
}


@Data
@Builder
public class WeatherResponse {
   
   

    public String location;

    public WeatherUnit unit;

    public int temperature;

    public String description;
}


WeatherResponse getCurrentWeather(Weather weather) {
   
   
    // mock function
    return WeatherResponse.builder()
            .location(weather.location())
            .unit(weather.unit())
            .temperature(new Random().nextInt(50))
