WSDL接口数据传递以及外网发布需要注意的地方

A系统传递数据给B系统

1、A创建asmx推送接口如下

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Services;
using Topevery.DUM.Report;
using Topevery.DUM.Report.Entity;

namespace Topevery.DUM.Report.ASMX
{
    /// <summary>
    /// PreEventFive 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 
    // [System.Web.Script.Services.ScriptService]
    public class PreEventFive : System.Web.Services.WebService
    {

        [WebMethod(Description = "直接返会json")]
       
        public string GetPETable()
        {
            DateTime now = DateTime.Now;
            DateTime d1 = new DateTime(now.Year, now.Month, 1);
            //DateTime d1 = Convert.ToDateTime ("2015-01-01");
            DateTime d2 = DateTime.Now;
            DataTable  dt = Broker.GetStatisTypeTop10(d1, d2, 1, "2").Tables[0];
            int i = 1;
            EventDataList DataSource = new EventDataList();
            List<Dictionary<string, object>> list = new List<Dictionary<string, object>>();
            foreach (DataRow dr in dt.Rows)
            {
                if (i < 6)
                {
                    DataSource.SerialNumber.Add(i.ToString());
                    DataSource.Name.Add(dr["C_NAME"].ToString());
                    DataSource.LNNUM.Add(dr["C_LA_NUM"].ToString());
                }
                i++;
            }
            //数组序列化转为json
            string jsonData2Tran = Newtonsoft.Json.JsonConvert.SerializeObject(DataSource);
           
            //Context.Response.Charset = "GB2312"; //设置字符集类型  
            //Context.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
            //Context.Response.Write(jsonData2Tran);
            //Context.Response.End();


            return jsonData2Tran;
        } 
    }
}

2、B引用A接口，接受该服务数据

JNEvent.PreEventFive ef = new JNEvent.PreEventFive();

            string pe = ef.GetPETable();

            PreEventFive evt = Newtonsoft.Json.JsonConvert.DeserializeObject<PreEventFive>(pe);

3、发布需要注意的是右击B接口，修改属性-web引用url，将localhost改为外网IP

4、发布后需要在该站点下<system.web>中间配置如下信息，开启远程访问

<webServices>
   <protocols>
    <add name="HttpSoap"/>
    <add name="HttpPost"/>
    <add name="HttpGet"/>
    <add name="Documentation"/>
   </protocols>
  </webServices>

个人还是觉得.asmx比.ashx方便得多
