本文介紹了使用C#調(diào)用deepseek API接口實(shí)現(xiàn)正常訪(fǎng)問(wèn)的方法,包括解決SSL/TLS安全通道問(wèn)題和切換模型等常見(jiàn)問(wèn)題,并提供了默認(rèn)使用的reasoner模型和賬戶(hù)余額信息,感興趣的朋友一起看看吧

先上圖,結(jié)果如圖

先去官方網(wǎng)站充值api費(fèi)用,默認(rèn)

對(duì)應(yīng)的C#代碼封裝

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
         {
             // 設(shè)置請(qǐng)求頭
             client.DefaultRequestHeaders.Clear();
             client.DefaultRequestHeaders.Add("Authorization", $"Bearer {apiKey}");
             client.DefaultRequestHeaders.Add("Accept", "application/json");
             // 構(gòu)建請(qǐng)求體
             var requestBody = new
             {
                 model = "deepseek-reasoner", // 根據(jù)實(shí)際模型調(diào)整
                 messages = new[]
                 {
                 new
                 {
                     role = "user",
                     content = userQuestion
                 }
             },
                 temperature = 0.7
             };
             // 序列化請(qǐng)求體
             //var jsonContent = JsonSerializer.Serialize(requestBody);
             var jsonContent = JsonConvert.SerializeObject(requestBody);
             var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
             // 發(fā)送請(qǐng)求
             var response = await client.PostAsync(ApiEndpoint, content);
             // 處理響應(yīng)
             if (!response.IsSuccessStatusCode)
             {
                 throw new Exception($"API請(qǐng)求失敗: {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)
         {
             // 處理異常
             return $"調(diào)用API時(shí)發(fā)生錯(cuò)誤: {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; }
     // 重寫(xiě)ToString方法以便更好地顯示對(duì)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相關(guān)的屬性...
     // 重寫(xiě)ToString方法以便更好地顯示Choice信息（這里僅展示Index和Message作為示例）
     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相關(guān)的屬性...
 }
 public class Usage
 {
     public int PromptTokens { get; set; }
     public int CompletionTokens { get; set; }
     public int TotalTokens { get; set; }
     // 其他Usage相關(guān)的屬性，包括嵌套的字典等，可以根據(jù)需要添加
 }

調(diào)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.");
       }
   }

常見(jiàn)問(wèn)題:

1發(fā)送請(qǐng)求時(shí)出錯(cuò) InnerException = {"請(qǐng)求被中止: 未能創(chuàng)建 SSL/TLS 安全通道。"}

指定使用TLS1.2加密協(xié)議,添加如下代碼

 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

2 收到內(nèi)容為空白

服務(wù)器繁忙,請(qǐng)把deepseek-chat模型切換到deepseek-reasoner 試試,或者換個(gè)時(shí)間再次嘗試.

模型區(qū)別如下.代碼中默認(rèn)使用了reasoner模型,俗稱(chēng)滿(mǎn)血版.

默認(rèn)賬戶(hù)贈(zèng)送10元余額.

到此這篇關(guān)于使用C# 調(diào)用deepseek api接口,來(lái)實(shí)現(xiàn)正常訪(fǎng)問(wèn)的文章就介紹到這了,更多相關(guān)C# 調(diào)用deepseek api內(nèi)容請(qǐng)搜索腳本之家以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持腳本之家！
