WCF REST开发-文件流多文件上传

来源：互联网发布：windows移动中心在哪编辑：程序博客网时间：2024/05/29 07:00

wcf rest主要是走路由来开发的API，配置路由：

public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            RegisterRoutes();
        }

        private void RegisterRoutes()
        {
            // Edit the base address of Service1 by replacing the "Service1" string below
            RouteTable.Routes.Add(new ServiceRoute("Service1", new WebServiceHostFactory(), typeof(Service1)));

            //测试
            RouteTable.Routes.Add(new ServiceRoute("SendInfo/testInfo", new WebServiceHostFactory(), typeof(WebWcfRest.SendInfo.testInfo)));

            //功能接口查询
            RouteTable.Routes.Add(new ServiceRoute("WCF/DataBase/IDbHelper", new WebServiceHostFactory(), typeof(WebWcfRest.WCF.DataBase.IDbHelper)));

            //极光推送
            RouteTable.Routes.Add(new ServiceRoute("WCF/AppApi/IApiOA", new WebServiceHostFactory(), typeof(WebWcfRest.WCF.AppApi.IApiOA)));

        }
    }

接口方法类：

[ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    [JavascriptCallbackBehavior(UrlParameterName = "callback")]
    public class IApiOA
    {
        #region 极光

        /// <summary>
        /// 批量推送消息
        /// 接口说明:Y 为必填 N 为可选填写
        /// </summary>
        /// <param name="toUserID">将要发送给用户的userid 可为数组(,分割) (Y) </param>
        /// <param name="title">推送标题 (N) </param>
        /// <param name="alert">推送 alert 信息 (Y) </param>
        /// <param name="msg_content">推送内容 (N) </param>
        /// <param name="RegistratingID">推送设备号 (N) </param>
        /// <returns>json 数据 </returns>
        [WebInvoke(
            Method = "GET",
            RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json,
            UriTemplate = "PushApp?toUserID={toUserID}&title={title}&alert={alert}&msg_content={msg_content}&RegistratingID={RegistratingID}")]
        public Stream PushApp(string toUserID, string title, string alert, string msg_content, string RegistratingID)
        {
            string json = "";
            StringBuilder str = new StringBuilder();
            int num = 0;
            bool state = false;
            if (!String.IsNullOrEmpty(toUserID))
            {
                //str.Append("001");
                var toUserIDList = toUserID.Split(',').ToList();
                if (toUserIDList.Count > 0)
                {
                    //str.Append("002");
                    for (int i = 0; i < toUserIDList.Count; i++)
                    {
                        //str.Append("003");
                        //拿到userID 后获取用户设备号 RegistratingID
                        ////----SqlDataProvider provider = new SqlDataProvider();
                        PageList_IDAO pageList = new PageList_Dal();
                        string sql = " select * from Base_UserInfo where DZM_ID = " + toUserIDList[i];
                        ////----DataTable dt = provider.SqlDataTable(sql);
                        DataTable dt = pageList.SelectSql(sql);
                        if (dt.Rows[0]["RegistratingID"].ToString() != "")
                        {
                            //str.Append("004");
                            bool bol = SwtichList(toUserIDList[i], title, alert, msg_content, dt.Rows[0]["RegistratingID"].ToString());
                            //str.Append("005");
                            if (bol)
                            {
                                //str.Append("006");
                                str.Append(toUserIDList[i]);
                            }
                        }
                        num = i;
                    }
                    state = true;
                }
            }
            //str.Append(toUserID + "---" + alert);
            json = "{\"state\":\"" + state + "\",\"number\":\"" + (num + 1) + "\",\"toUserID\":\"" + str.ToString() + "\",\"CDATA\":\"[{\"state\":\"返回状态 if 成功 ? true : false \",\"number\":\"修改成功个数\"}]\"}";
            //return json;
            return new MemoryStream(Encoding.UTF8.GetBytes(json));
        }

    }
}

可GET post put 等其他一般用不到
