开发个人Go-ChatGPT–5 模型管理 (二)

ChatGPT

这是该项目的最终效果，使用ollama的open-webui进行人与机器的对话功能，对话的后端服务则完全对接自己开发的Go项目。
chatgpt
如何实现呢？则通过这篇文章，一一给大家剖析后端的原理及功能实现。

请添加图片描述

根据上图结果，生成的stream响应，就可与open-webUI进行对话，实现ChatGPT的功能效果。

5.1 生成 chat model 模型

创建 chat.sql，生成chat相关数据表。字段不可缺少任意一个，否则open-webui无法正常展示

CREATE TABLE `chat` (
	`id` bigint unsigned NOT NULL AUTO_INCREMENT,
    `user_id` varchar(255)  NOT NULL DEFAULT '' COMMENT '用户ID',
    `title` varchar(255)  NOT NULL DEFAULT '' COMMENT '标题',
	`chat` longtext  NOT NULL COMMENT '',
	`archived` tinyint(1) unsigned NOT NULL DEFAULT '0' COMMENT '',
    `share_id` varchar(255)  NOT NULL DEFAULT '' COMMENT '分享用户ID',
	`create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
	`update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
	PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8mb4;

创建prompt.sql，生成prompt相关数据表。字段不可缺少任意一个，否则open-webui无法正常展示

drop table if exists prompt;
CREATE TABLE `prompt` (
                          `id` bigint unsigned NOT NULL AUTO_INCREMENT,
                          `command` varchar(255)  NOT NULL DEFAULT '' COMMENT '命令',
                          `user_id` varchar(255)  NOT NULL DEFAULT '' COMMENT '用户ID',
                          `title` varchar(255)  NOT NULL DEFAULT '' COMMENT '标题',
                          `content` longtext  NOT NULL COMMENT '文本',
                          `create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
                          `update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
                          PRIMARY KEY (`id`),
                          UNIQUE KEY `command` (`command`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8mb4;

运行模板生成命令 model文件放置在通用目录，和go-zero官方案例不同

# chat model
goctl model mysql ddl -src ./model/chat.sql -dir ./model -c

# prompt model
goctl model mysql ddl -src ./model/prompt.sql -dir ./model -c

5.2 生成 chat api 服务

前缀，路由，传参，响应不可变，否则 openui调用失败

创建 chat.api 文件

type (
	// 产品创建
	CreateRequest {
		UserId   string `json:"userId"`

运行模板生成命令

goctl api go -api ./api/chat.api -dir ./api

5.3 生成 user rpc 服务

创建 chat.proto文件

syntax = "proto3";

package chat;

option go_package = "./chat";

message Empty {
}
// 产品创建
message CreateRequest {
    string UserId = 1;
    string Title = 2;
    string Chat = 3;
    string ShareId = 4;
    int64 Archived = 5;
}
message CreateResponse {
    int64 Id = 1;
}
// 产品创建

// 产品修改
message UpdateRequest {
    int64 Id = 1;
    string UserId = 2;
    string Title = 3;
    string Chat = 4;
    string ShareId = 5;
    int64 Archived = 6;
}
message UpdateResponse {
}
// 产品修改

// 产品删除
message RemoveRequest {
    int64 Id = 1;
}
message RemoveResponse {
}
// 产品删除

// 产品详情
message DetailRequest {
    int64 Id = 1;
}
message DetailResponse {
    int64 Id = 1;
    string UserId = 2;
    string Title = 3;
    string Chat = 4;
    string ShareId = 5;
    int64 Archived = 6;
}
// 产品详情

message ListChats {
    repeated DetailResponse List = 1;
}

// 调用ollama 大模型
message CallRequest {
    string Name = 1;
    string Prompt = 2;
    string Role = 3;
}

message CallResponse {
    string Text = 1;
}

message Prompt {
    int64 Id = 1;
    string Command = 2;
    string Title = 3;
    string UserId = 4;
    string Content = 5;
}

message ListPrompts{
    repeated Prompt List = 1;
}

message NewChatEntity {
    string Model = 1;
    repeated MessagesEntity Messages = 2;
    OptionsEntity Options = 3;
}

message MessagesEntity {
    string Role = 1;
    string Content = 2;
}

message OptionsEntity {}

service Chat {
    rpc Create(CreateRequest) returns(CreateResponse);
    rpc Update(UpdateRequest) returns(UpdateResponse);
    rpc Remove(RemoveRequest) returns(RemoveResponse);
    rpc Detail(DetailRequest) returns(DetailResponse);

    rpc ListChat(Empty) returns(ListChats);
    rpc ListPrompt(Empty) returns(ListPrompts);

    rpc Call(CallRequest) returns(CallResponse);

    rpc GenPrompt(NewChatEntity) returns(CallResponse);
}

运行模板生成命令

goctl rpc protoc ./rpc/chat.proto --go_out=./rpc/types --go-grpc_out=./rpc/types --zrpc_out=./rpc
