java对接kimi详细说明，附完整项目

需求：

使用java封装kimi接口为http接口，并把调用kimi时的传参和返回数据，保存到mysql数据库中

自己记录一下，以做备忘。

具体步骤如下：

1.申请apiKey

访问：Moonshot AI - 开放平台使用手机号+手机号验证码登录

登录后，在如下界面申请：

最多可以保留 5 个 API 密钥，密钥只会在新建后显示一次，请妥善保存。不要与他人共享 API Key，或将其暴露在客户端代码中。为了账户安全，一旦 API 密钥被发现泄露，Moonshot AI 可能会将其禁用。

默认token数量如下：

2.编写Java代码对接kimi

2.1对接kimi日志表

CREATE TABLE `ai_api_log` (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',`api_key` varchar(50) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT 'app_key',`api_ip` varchar(50) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT 'API调用外网IP',`api_method` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT 'API方法',`api_para` text COLLATE utf8mb4_unicode_ci COMMENT 'API参数',`api_result` text COLLATE utf8mb4_unicode_ci COMMENT 'API返回消息',`create_time` datetime DEFAULT NULL COMMENT '创建时间 ',PRIMARY KEY (`id`),KEY `open_api_log_creat_time` (`create_time`),KEY `open_api_log_method` (`api_method`),KEY `open_api_log_app_key` (`api_key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='api日志'

表对应的实体类

package com.example.ai.domain;import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;
import lombok.EqualsAndHashCode;import java.util.Date;
@Data
@EqualsAndHashCode(callSuper = true)
@TableName("ai_api_log")
public class AIApiLog extends BaseEntity {private static final long serialVersionUID=1L;public static String METHOD_KIMI_CHAT="kimi_chat";private Integer id;private String apiKey;private String apiIp;private String apiMethod;private String apiPara;private String apiResult;private Date createTime;}
