访问deep seek平台首先需要去deep seek平台的api开放平台创建一个API key，这是首要前提，然后再使用下面这个脚本

 string url = "https://api.deepseek.com/v1/chat/completions";

  string key = "Bearer "+"自己的key";

public Text text1;

 IEnumerator PostData(Action action  )
    {
        
        string jsonData = text1.text ;
        byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(jsonData);
        UnityWebRequest request = new UnityWebRequest(url, "POST");
        request.SetRequestHeader("Authorization", key);
        request.SetRequestHeader("Content-Type", "application/json");
        request.uploadHandler = new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = new DownloadHandlerBuffer(); 
        yield return request.SendWebRequest(); 
        print(request.downloadHandler.text);
        action();
        
    }

text1的内容为

{  "messages": [
    {
      "content": "今天的天气如何",
      "role": "system"
    },
    {
      "content": "Hi",
      "role": "user"
    }
  ],
  "model": "deepseek-chat",
  "frequency_penalty": 0,
  "max_tokens": 2048,
  "presence_penalty": 0,
  "response_format": {
    "type": "text"
  }
}

把这个弄好后直接调用方法即可，这样就能和deepseek沟通了（=那个json是我懒得写了=）
