c#导入百度统计API数据

最近项目中需要增加一些新功能：当前在线人数，总访问量统计，今日访问量，上一年度访问量，找了很多第三方统计工具，最后确定用百度统计，因为项目是vue的，直接引入的时候出现了跨域，发现前端用jsonp解决不了，所以就直接用c#请求再返回给前端了，话不多说，具体操作如下（本人最近新学c#，欢迎大佬指正）

首先去百度统计官网注册登录站长号，然后在需要统计的网站加入代码，获得token，这些不多说

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 = "百度统计站长用户名", password = "百度统计站长密码", token = "token" }; var bodya = new { site_id = "网站id", start_date = "20200528", //是5.28加的百度统计代码，所以从5.28开始计算 end_date = endDate, metrics = "pv_count,visitor_count", method = "source/all/a", //总访问量 tab = "visit" }; var bodyb = new { site_id = "网站id", start_date = "", end_date = endDate, metrics = "pv_count,visitor_count", method = "source/all/a", //当日访问量 tab = "visit" }; var bodyc = new { site_id = "网站id", start_date = laststartDate, end_date = LastendDate, //start_date = "20200101", //end_date ="20201231", metrics = "", method = "source/all/a", //上一年度访问量 tab = "visit" }; var bodyd = new { site_id = "网站id", start_date = "", end_date = "", metrics = "", method = "/trend/latest/f", //当日在线人数 tab = "visit" }; Object[] bodyList = new Object[4] { bodya, bodyb, bodyc, bodyd }; //我这里是想一次将需要的四条数据 都返回，所以就写了个数组，将四组数据放里面，以循环的方式进行四次请求 int count = 0,currentDay=0,currentLast=0, onlineNumber=0; //定义四个变量，分别在后面接收需要的四个数据 //循环请求百度的接口 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(); byte[] byte1 = encoding.GetBytes(jResult); var content = new ByteArrayContent(byte1); content.Headers.ContentType = MediaTypeHeaderValue.Parse("application/x-www-form-urlencoded"); var response = httpClient.PostAsync(url, content).Result; string results = response.Content.ReadAsStringAsync().Result; //因为返回的数据格式不一样（统计访问量和获取当前在线的不一样）所以需要先定义两组不同的数据类型 }

定义类型

获取访问量的 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; } } 获取当前在线人数 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; } } }

将返回来的数据转换成自己需要的

var model = JsonConvert.DeserializeObject<BaiduModel>(results); if (model.Body.Data[0].Result.Sum != null) if (i == 0) { List<List<string>> sumList = model.Body.Data[0].Result.Sum; List<string> sumNumAll = sumList[0]; if (sumNumAll[0] == "--") { count = 0; } else { count = int.Parse(sumNumAll[0]); } }; if (i == 1) { List<List<string>> sumList = model.Body.Data[0].Result.Sum; List<string> sumNumAll = sumList[0]; if (sumNumAll[0] == "--") { currentDay = 0; } else { currentDay = int.Parse(sumNumAll[0]); } }; if (i == 2) { List<List<string>> sumList = model.Body.Data[0].Result.Sum; List<string> sumNumAll = sumList[0]; if (sumNumAll[0] == "--") { currentLast = 0; } else { currentLast = int.Parse(sumNumAll[0]); } }; if (i == 3) { var modela = JsonConvert.DeserializeObject<BaiduModela>(results); int OnlineNum = modela.Body.Data[0].Result.OnlineNumber; onlineNumber = OnlineNum; }; } result.Data = new { Count = count, CurrentDay = currentDay, CurrentLast = currentLast, OnlineNumber = onlineNumber };
