c#導入百度統計API數據

最近項目中需要增加一些新功能：當前在線人數，總訪問量統計，今日訪問量，上一年度訪問量，找了很多第三方統計工具，最後確定用百度統計，因爲項目是vue的，直接引入的時候出現了跨域，發現前端用jsonp解決不了，所以就直接用c#請求再返回給前端了，話不多說，具體操作如下（本人最近新學c#，歡迎大佬指正）

首先去百度統計官網註冊登錄站長號，然後在需要統計的網站加入代碼，獲得token，這些不多說

AjaxResult result = new AjaxResult();
            var endDate = DateTime.Now.ToString("yyyyMMdd");
            var laststartDate = DateTime.Now.Year - 1 + "0101";
            var LastendDate = DateTime.Now.Year - 1 + "1231";
            string url = "https://api.baidu.com/json/tongji/v1/ReportService/getData";
            var header = new
            {
                account_type = 1,
                username = "百度統計站長用戶名",         
                password = "百度統計站長密碼",         
                token = "token"      
            };
            var bodya = new
            {
                site_id = "網站id",           
                start_date = "20200528",        //是5.28加的百度統計代碼，所以從5.28開始計算
                end_date = endDate,
                metrics = "pv_count,visitor_count",
                method = "source/all/a",     //總訪問量
                tab = "visit"
            };
            var bodyb = new
            {
                site_id = "網站id",
                start_date = "",
                end_date = endDate,

            var bodyc = new
            {
                site_id = "網站id",
                start_date = laststartDate,
                end_date = LastendDate,
                //start_date = "20200101",
                //end_date ="20201231",
                metrics = "",
                method = "source/all/a",     //上一年度訪問量

                method = "/trend/latest/f",     //當日在線人數
                tab = "visit"
            };
            Object[] bodyList = new Object[4] { bodya, bodyb, bodyc, bodyd }; //我這裏是想一次將需要的四條數據              都返回，所以就寫了個數組，將四組數據放裏面，以循環的方式進行四次請求
            int count = 0,currentDay=0,currentLast=0, onlineNumber=0;   //定義四個變量，分別在後面接收需要的四個數據
//循環請求百度的接口
             for (int i = 0; i < bodyList.Length; i++)
                {
                    var body = bodyList[i];
                    var postData = new { header, body };
                    string jResult = JsonConvert.SerializeObject(postData);
                    AjaxResult ajaxresult = new AjaxResult();
                    HttpClient httpClient = new HttpClient();
                    UTF8Encoding encoding = new UTF8Encoding();

                    string results = response.Content.ReadAsStringAsync().Result;
                    //因爲返回的數據格式不一樣（統計訪問量和獲取當前在線的不一樣）所以需要先定義兩組不同的數據類型
                    }

定義類型

獲取訪問量的
 public class BaiduModel
    {
        public BaiduBody Body { get; set; }
    }
    public class BaiduBody
    {
        public List<BaiduListItem> Data { get; set; }
    }

    public class BaiduListItem
    {
        public BaiduResult Result { get; set; }
        
    }

    public class BaiduResult
    {
        public List<List<string>> Sum { get; set; }
    }

獲取當前在線人數
 public class BaiduModela
    {
        public BaiduBodya Body { get; set; }
    }
    public class BaiduBodya
    {
        public List<BaiduListItema> Data { get; set; }
    }

    public class BaiduListItema
    {
        public BaiduResulta Result { get; set; }

    }
    public class BaiduResulta
    {
        public int OnlineNumber { get; set; }
    }

}

將返回來的數據轉換成自己需要的

                    {
                        List<List<string>> sumList = model.Body.Data[0].Result.Sum;
                        List<string> sumNumAll = sumList[0];

                        }

                    };
                    if (i == 3)
                    {
                        var modela = JsonConvert.DeserializeObject<BaiduModela>(results);
                        int OnlineNum = modela.Body.Data[0].Result.OnlineNumber;
                        onlineNumber = OnlineNum;
