篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了批量发送短信，并批量插入短信记录相关的知识，希望对你有一定的参考价值。
最近在项目中遇到了群发短信的需求。
需求点包括：
1.给符合条件的人群发优惠券短信
2.并对发送短信做记录，成功或者失败。（SqlServer）
短信接口：
亿美，api中有群发短信的接口，一组最大为200条。
思路：
1.发送的手机集合放进一个队列
2.依次读取队列，放到待发送列表，当满足200（短信组个数可配置在web.config中）条时，调用接口发送，直到队列数据发完
3.发送结果放进已发送短信结果集合
4.把发送结果批量插入数据库
代码：
群发helper
/// <summary> /// 群发短信 /// </summary> public class SmsGroupHelper { //每次发送短信数量 private readonly static int SmsCount = Globals.SafeInt(Utils.GetAppSettingByKey("SmsCount"), 0); /// <summary> /// 群发短信 /// </summary> /// <param name="content">短信内容</param> /// <param name="phones">手机号组</param> /// <returns></returns> public static SmsResult SendGroupSms(string content, List<string> phones) { var phoneQueue = new Queue<string>(); var unSendSmsList = new List<string>(); //待发送 var sendedSmsList = new List<Sms>(); //已发送数量 var sendFailed = new List<string>(); //发送失败数量 var sendSuccess = new List<string>(); //发送成功数量 var smsResult = new SmsResult(); smsResult.ErrMsg = "无"; try { //1.先发送短信 ，根据短信发送情况，保存数据库记录 foreach (var phone in phones) { phoneQueue.Enqueue(phone); } //是否发送短信 var isSendFlag = false; while (true) { if (phoneQueue.Count > 0) { var phoneNum = phoneQueue.Dequeue(); unSendSmsList.Add(phoneNum); //如果达到一个发送短信包数量 if (unSendSmsList.Count == SmsCount) { isSendFlag = true; } } else { //如果还有短信没发出去 if (unSendSmsList.Count > 0) { isSendFlag = true; } else { isSendFlag = false; break; } } if (isSendFlag) { var phoneArr = unSendSmsList.ToArray(); var resposeMsg = ""; //发送短信短信接口 var flag = SMSHelper.SendSms(content, phoneArr, out resposeMsg); var sendResult = "短信发送成功"; if (flag) { sendSuccess.AddRange(unSendSmsList); } else { sendResult = "短信发送失败"; sendFailed.AddRange(unSendSmsList); } //记录总发送数量 sendedSmsList.AddRange( unSendSmsList.Select( un => new Sms { Phone = un, CreateTime = DateTime.Now, MessageStatus = sendResult, MessageRemarks = content })); //清空未发送列表 unSendSmsList = new List<string>(); isSendFlag = false; } } } catch (Exception ex) { smsResult.ErrMsg = ex.Message; while (phoneQueue.Count > 0) { var p = phoneQueue.Dequeue(); sendFailed.Add(p); sendedSmsList.Add(new Sms() { Phone = p, CreateTime = DateTime.Now, MessageStatus = "短信发送失败", MessageRemarks = content }); } } //批量插入短信结果到数据库 DapperHelper.BulkInsert("SmsRecord", sendedSmsList); smsResult.Send = sendedSmsList.Count; smsResult.Success = sendSuccess.Count; smsResult.Failed = sendFailed.Count; return smsResult; }
批量插入数据
public class TableColumn { public string COLUMN_NAME { get; set; } public string DATA_TYPE { get; set; } }
#region Bulk批量插入 public static Type MapCommonType(string dbtype) { if (string.IsNullOrEmpty(dbtype)) return Type.Missing.GetType(); dbtype = dbtype.ToLower(); Type commonType = typeof(object); switch (dbtype) { case "bigint": commonType = typeof(long); break; case "binary": commonType = typeof(byte[]); break; case "bit": commonType = typeof(bool); break; case "char": commonType = typeof(string); break; case "date": commonType = typeof(DateTime); break; case "datetime": commonType = typeof(DateTime); break; case "datetime2": commonType = typeof(DateTime); break; case "datetimeoffset": commonType = typeof(DateTimeOffset); break; case "decimal": commonType = typeof(decimal); break; case "float": commonType = typeof(double); break; case "image": commonType = typeof(byte[]); break; case "int": commonType = typeof(int); break; case "money": commonType = typeof(decimal); break; case "nchar": commonType = typeof(string); break; case "ntext": commonType = typeof(string); break; case "numeric": commonType = typeof(decimal); break; case "nvarchar": commonType = typeof(string); break; case "real": commonType = typeof(Single); break; case "smalldatetime": commonType = typeof(DateTime); break; case "smallint": commonType = typeof(short); break; case "smallmoney": commonType = typeof(decimal); break; case "sql_variant": commonType = typeof(object); break; case "sysname": commonType = typeof(object); break; case "text": commonType = typeof(string); break; case "time": commonType = typeof(TimeSpan); break; case "timestamp": commonType = typeof(byte[]); break; case "tinyint": commonType = typeof(byte); break; case "uniqueidentifier": commonType = typeof(Guid); break; case "varbinary": commonType = typeof(byte[]); break; case "varchar": commonType = typeof(string); break; case "xml": commonType = typeof(string); break; default: commonType = typeof(object); break; } return commonType; } //获取表结构 public static List<TableColumn> GetTableColumns(string tableName) { var columns = DapperHelper.GetList<TableColumn>( string.Format( "select COLUMN_NAME,DATA_TYPE from INFORMATION_SCHEMA.COLUMNS t where t.TABLE_NAME = ‘{0}‘", tableName), null); return columns; } /// <summary> /// 获取表数据 /// </summary> /// <param name="tableName">数据表名称</param> /// <param name="lists">数据集合</param> /// <returns></returns> public static void BulkInsert<T>(string tableName, List<T> lists) { var type = typeof (T); var fields = type.GetProperties(); var columns = GetTableColumns(tableName); DataTable dt = new DataTable(); foreach (var column in columns) { dt.Columns.Add(new DataColumn(column.COLUMN_NAME, MapCommonType(column.DATA_TYPE))); } foreach (var l in lists) { var row = dt.NewRow(); foreach (var column in columns) { var column1 = column; foreach (var field in fields.Where(field => String.Equals(column1.COLUMN_NAME, field.Name, StringComparison.CurrentCultureIgnoreCase))) { row[column.COLUMN_NAME] = field.GetValue(l) ??
