上一篇博文已经介绍了怎么搭建BotSharp本地大模型环境
https://blog.csdn.net/zxy13826134783/article/details/156653773?spm=1001.2014.3001.5501
本文运行环境：
win11
visual studio 2022
本文利用C#对接BotSharp本地大模型的Api,废话不多说，先上代码及运行结果
1 在Vistual Studio中新建名为POSTDemo1的控制台项目，选择.net framework 4.7
2 利用nuget安装Newtonsoft.Json及System.Text.Json，直接安装最新版就行
3 编辑代码如下：
cs
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Text.Json;
using System.Threading.Tasks;
namespace POSTDemo1
{
internal class Program
{
static void Main(string[] args)
{
var base_url = $"http://localhost:5500";
string userName = "admin@gmail.com";
string password = "123456";
string token = GetToken(base_url,userName, password);
if (string.IsNullOrEmpty(token))
{
Console.WriteLine("获取token失败");
return;
}
//解析token
JsonDocument doc = JsonDocument.Parse(token);
string accessToken = doc.RootElement
.GetProperty("access_token")
.GetString();
if(string.IsNullOrEmpty(accessToken))
{
Console.WriteLine("获取access_token失败");
return;
}
Console.WriteLine($"获取到的token{accessToken}");
//输入的问题
string question = "hello";
//发送对话
PostConverSation(base_url, accessToken, question);
Console.WriteLine("运行完毕");
Console.ReadLine();
}
private static void SetClientHeader(HttpClient client,string authorization)
{
client.DefaultRequestHeaders.Authorization =
new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", authorization);
}
private static void PostConverSation(string base_url,string token,string question)
{
var client = new HttpClient();
string agentId = "01e2fc5c-2c89-4ec7-8470-7688608b496c";
//会话Id
string conversationId = "abc";
string converSationUrl = $"{base_url}/conversation/{agentId}/{conversationId}";
SetClientHeader(client, token);
var data = new
{
text = question,
provider = "llama-sharp",
model = "llama-2-7b-chat.Q8_0.gguf"
};
Console.WriteLine($"输入的问题:{question}");
string ret=PostJsonData(client, converSationUrl, data, 3);
Console.WriteLine($"机器人回复:{ret}");
}
private static string PostJsonData(HttpClient client,string url,object data,int timeOut)
{
string jsonContent = "";
if (data != null)
{
jsonContent= JsonConvert.SerializeObject(data);
}
var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
string result = "";
try
{
client.Timeout = TimeSpan.FromMinutes(timeOut); // 设置超时时间
var response = client.PostAsync(url, content).Result;
if (response.IsSuccessStatusCode)
{
var responseJson = response.Content.ReadAsStringAsync().Result;
result= responseJson;
}
else
{
Console.WriteLine($"Error: {response.StatusCode}");
}
}
catch (HttpRequestException e)
{
Console.WriteLine($"Network error: {e.Message}");
}
return result;
}
private static string GetToken(string base_url,string userName,string password)
{
string credentials=Convert.ToBase64String(Encoding.UTF8.GetBytes($"{userName}:{password}"));
string authorization = $"Basic {credentials}";
var client = new HttpClient();
string tokenUrl = $"{base_url}/token";
SetClientHeader(client, authorization);
return PostJsonData(client, tokenUrl, null, 1);
}
}
}先启动BotSharp后台服务，再运行该代码，运行结果如下：
机器人回复的文本：

}同时也可以看到BotSharp的控制台日志有输出回复：
不知道是不是电脑配置问题，输入问题后，要很久才获取到回复，有时候3分钟都没回复就报错了
先要获取到token，token信息从前端BotSharp-UI中的代码中获取到启发
模型的代理agentId是固定的
会话conversationId是唯一的，自己定义，我这里为了偷懒，正常来说还得再调用一个接口(在BotSharp-UI前端界面新建会话时会调用)，相当于设置会话Id,直接运行上述代码也会创建会话，但第一次可能返回的结果不是需要的结果，运行第二次就正常了
代理agentId及conversationId可以通过这里直接获取到：
点击上台右边chat小图标，直接进入会话，如下图：
看上图中的浏览器地址栏这里，已经标注AgentId及conversationId
