Asp.Net MVC 讀取json文件

有些系統上面的配置可以做成config裏面的appsetting。這裏要求寫在json文件裏面。

 首先 添加命名空間 

using Newtonsoft.Json;
using System.IO;
using Newtonsoft.Json.Linq;
using System.Web;

 下面是我json文件裏面的內容 因爲西門下面的序號是 變動的就寫在配置文件裏面也好修改

{
  "StatisticalChart": {
    "0": "/Common/CountReport/DefaultStatis", 
    "68": "/Common/CountReport/CustomerManagerStatis", 
    "98": "/Common/CountReport/FirstExamineStatis",
    "84": "/Common/CountReport/QualityCheckStatis", 
    "112": "/Common/CountReport/ElectricFinalCheckStatis", 
    "70": "/Common/CountReport/ExecutiveDirectorStatis" 
  },
  "NameGetCode":{
    "Default": "0",
    "CustomerManager": "68",
    "FirstExamine": "98",
    "QualityCheck": "84",
    "ElectricFinalCheck": "112",
    "ExecutiveDirector": "70"
  }
}

 

下面是讀取StatisticalChart節點裏面的內容 power權限參數 用戶登錄之後獲得。

/// <summary>
        /// 通過角色讀取配置文件返回地址
        /// </summary>
        /// <param name="power">權限編號</param>
        /// <returns></returns>
        public static string GetUrlByPower(string power)
        {
            string url = "";
            try
            {
                //文件路徑
                string jsonfile = HttpContext.Current.Server.MapPath($"\\App_Data\\config\\StatisticalChartConfig.json");
                //打開文件
                System.IO.StreamReader file = System.IO.File.OpenText(jsonfile);
                //加載問卷
                JsonTextReader reader = new JsonTextReader(file);
                //轉化爲JObject
                JObject ojb = (JObject)JToken.ReadFrom(reader);
                //讀取StatisticalChart節點
                var list = ojb["StatisticalChart"].ToString();
                JObject jo = (JObject)JsonConvert.DeserializeObject(list);
                var dat = jo[power];
                if (dat == null)
                    url = "";
                else
                    url = dat.ToString();
            }
            catch (Exception e)
            {
                url = "";
                throw new Exception($"初始化JSON流程配置失敗:{e.Message}");
            }
            return url;
        }

 

另外一種 中國省市縣的json文件

讀取的方法（我是通過身份證號碼獲取信息用到的）

 //讀取json文件獲取代碼對應的省市縣
                string jsonfile =HttpContext.Current.Server.MapPath($"\\App_Data\\Config\\AreasData.json");
                StreamReader file = File.OpenText(jsonfile);
                JsonTextReader reader = new JsonTextReader(file);
                var obj = JToken.ReadFrom(reader).ToList();
                for (int i = 0; i < obj.Count; i++)
                {
                    JObject jo = (JObject)JsonConvert.DeserializeObject(obj[i].ToString());
                    if (jo["zoneCode"].ToString() == AreasCodess)
                    {
                        var Data = new AreasCode()
                        {
                            Province = jo["province"].ToString(),
                            ProvinceCode = jo["provinceCode"].ToString(),
                            City = jo["city"].ToString(),
                            CityCode = jo["cityCode"].ToString(),
                            Country = jo["zone"].ToString(),
                            CountryCode = jo["zoneCode"].ToString()
                        };
                        list.Add(Data);
                        break;
                    }

                }

 

AreasCode是個實體類 接收參數的Model，AreasCodess是區域代碼。讀取json文件代碼就這些 全面幾步都是一樣的 後面要看具體的json文件格式，就跟Ajax一樣 返回來數據類型 是後臺決定的你纔好解析！

 

獲取身份證信息也貼上吧，後面用到又來拿

/// <summary>
        /// 獲取身份證信息
        /// </summary>
        /// <param name="identityCard">身份證號碼</param>

        /// <returns>List->IDCard模型</returns>
        public static List<IDCard> GetIDCardInfo(string identityCard, bool ageIsTrue = true)
        {

            if (string.IsNullOrEmpty(identityCard))//爲空返回null
                return null;
            else
            {
                if (identityCard.Length != 15 && identityCard.Length != 18)//身份證號碼只能爲15位或18位其它不合法

                strSex = identityCard.Substring(14, 3);//
            }
            //530323 670401 001的含義; 530爲雲南，03爲曲靖 ，23是師宗，出生日期爲1967年4月1日，順序號爲001。

                card.Sex = "女";
            else
