我要评论先上图,结果如图
先去官方网站充值api费用,默认
对应的c#代码封装
public class deepseekhelper
{
private static readonly httpclient client = new httpclient();
private const string apiendpoint = "https://api.deepseek.com/v1/chat/completions";
private static readonly string apikey = "你的apikey";
public static async task<string> calldeepseekapi(string userquestion)
{
servicepointmanager.securityprotocol = securityprotocoltype.tls12;
try
{
// 设置请求头
client.defaultrequestheaders.clear();
client.defaultrequestheaders.add("authorization", $"bearer {apikey}");
client.defaultrequestheaders.add("accept", "application/json");
// 构建请求体
var requestbody = new
{
model = "deepseek-reasoner", // 根据实际模型调整
messages = new[]
{
new
{
role = "user",
content = userquestion
}
},
temperature = 0.7
};
// 序列化请求体
//var jsoncontent = jsonserializer.serialize(requestbody);
var jsoncontent = jsonconvert.serializeobject(requestbody);
var content = new stringcontent(jsoncontent, encoding.utf8, "application/json");
// 发送请求
var response = await client.postasync(apiendpoint, content);
// 处理响应
if (!response.issuccessstatuscode)
{
throw new exception($"api请求失败: {response.statuscode}");
}
var responsecontent = await response.content.readasstringasync();
var resultmodel = jsonconvert.deserializeobject<deepseekresponse>(responsecontent);
if (resultmodel != null && resultmodel.choices.count > 0)
return resultmodel.choices[0].message.content;
return responsecontent;
}
catch (exception ex)
{
// 处理异常
return $"调用api时发生错误: {ex.message}";
}
}
}
public class deepseekresponse
{
public string id { get; set; }
public string object { get; set; }
public long created { get; set; }
public string model { get; set; }
public list<choice> choices { get; set; }
public usage usage { get; set; }
public string systemfingerprint { get; set; }
// 重写tostring方法以便更好地显示对象信息
public override string tostring()
{
return $"deepseekresponse(id={id}, object={object}, created={created}, model={model}, choices={string.join(", ", choices)}, usage={usage}, systemfingerprint={systemfingerprint})";
}
}
public class choice
{
public int index { get; set; }
public message message { get; set; }
// 其他choice相关的属性...
// 重写tostring方法以便更好地显示choice信息（这里仅展示index和message作为示例）
public override string tostring()
{
return $"choice(index={index}, message={message})";
}
}
public class message
{
public string role { get; set; }
public string content { get; set; }
// 其他message相关的属性...
}
public class usage
{
public int prompttokens { get; set; }
public int completiontokens { get; set; }
public int totaltokens { get; set; }
// 其他usage相关的属性，包括嵌套的字典等，可以根据需要添加
}调用示例
private async void sendbutton_click(object sender, routedeventargs e)
{
string requesttext = requesttextbox.text;
if (!string.isnullorwhitespace(requesttext))
{
try
{
string responsedata = await deepseekhelper.calldeepseekapi(requesttext); // await new deepseekapi().calldeepseekapi(chatrequest);
responsetextbox.text = responsedata;
}
catch (exception ex)
{
responsetextbox.text = $"error: {ex.message}";
}
}
else
{
messagebox.show("please enter a request.");
}
}常见问题:
1发送请求时出错 innerexception = {"请求被中止: 未能创建 ssl/tls 安全通道。"}
指定使用tls1.2加密协议,添加如下代码
servicepointmanager.securityprotocol = securityprotocoltype.tls12;
2 收到内容为空白
服务器繁忙,请把deepseek-chat模型切换到deepseek-reasoner 试试,或者换个时间再次尝试.
模型区别如下.代码中默认使用了reasoner模型,俗称满血版.
