1.獲取AccessToken

https://ding-doc.dingtalk.com/doc#/serverapi2/eev437

private static string GetAccessToken()
        {
            DefaultDingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/gettoken");
            OapiGettokenRequest request = new OapiGettokenRequest();
            request.Appkey = "Appkey";//填寫對應的Appkey
            request.Appsecret = "Appsecret ";//填寫對應的Appsecret 
            request.SetHttpMethod("GET");
            OapiGettokenResponse response = client.Execute(request);

            string result = response.AccessToken;
            return result;
        }

2.上傳釘盤文件

單步上傳文件，文件大小不得超過8M。

  /// <summary>
        /// 通過釘盤 上傳文件
        /// </summary>
        /// <param name="filePath"></param>
        /// <returns></returns>
        public static string UploadFile(string filePath)
        {
            OapiFileUploadSingleRequest request = new OapiFileUploadSingleRequest();
            request.FileSize=(1000L);
            request.AgentId=("AgentId");//填寫對應的AgentId
            IDingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/file/upload/single?" + WebUtils.BuildQuery(request.GetParameters()));
            // 必須重新new一個請求
            request = new OapiFileUploadSingleRequest();
            request.File=(new FileItem(filePath));
            OapiFileUploadSingleResponse response = client.Execute(request, Get_CorPsecret());
            return response.Body;//返回文件存儲id
        }

3.發送文件給用戶

        /// <summary>
        /// 通過釘盤里面的文件發送給用戶
        /// </summary>
        /// <param name="userID"></param>
        /// <param name="mediaID"></param>
        /// <param name="fileName"></param>
        /// <returns></returns>
        public static string SendUserMedia(string userID, string mediaID,string fileName)
        {
            OapiCspaceAddToSingleChatRequest request = new OapiCspaceAddToSingleChatRequest();
            request.AgentId= "AgentId";//填寫對應的AgentId
            request.Userid=("Userid");//釘釘用戶對應ID
            request.MediaId = HttpUtility.UrlEncodeUnicode(mediaID);
            request.FileName= fileName;
            IDingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/cspace/add_to_single_chat?" + WebUtils.BuildQuery(request.GetParameters()));
            OapiCspaceAddToSingleChatResponse response = client.Execute(request, Get_CorPsecret());
            return response.Body; 
        }
