发请求响应文本 

添加一个实体, 用于设置发请求的参数：

import java.io.Serializable;
import java.util.List;
 
/**
 * api请求的参数
 *
 * @author 提笔忘字的帝国
 */
public class Text implements Serializable {
 
    private static final long serialVersionUID = 1L;
    /**
     * model : gpt-3.5-turbo messages : [{"role":"user","content":"Say this is a test!"}] temperature : 0.7
     */
 
    private String model;
    private double temperature;
    private List<MessagesBean> messages;
 
    public String getModel() {
        return model;
    }
 
    public void setModel(String model) {
        this.model = model;
    }
 
    public double getTemperature() {
        return temperature;
    }
 
    public void setTemperature(double temperature) {
        this.temperature = temperature;
    }
 
    public List<MessagesBean> getMessages() {
        return messages;
    }
 
    public void setMessages(List<MessagesBean> messages) {
        this.messages = messages;
    }
 
    public static class MessagesBean implements Serializable {
        private static final long serialVersionUID = 1L;
        /**
         * role : user content : Say this is a test!
         */
 
        private String role;
        private String content;
 
        public MessagesBean(String user, String content) {
            this.role = user;
            this.content = content;
        }
 
        public String getRole() {
            return role;
        }
 
        public void setRole(String role) {
            this.role = role;
        }
 
        public String getContent() {
            return content;
        }
 
        public void setContent(String content) {
            this.content = content;
        }
    }

 可以看到响应回来的是一个图像的链接, 点击查看链接即可, 下图是生成回来的图像

emmmm, 跟我想象的不一样, 可能是我描述不够清晰, 今天就到这啦~
