webservice和一般处理程序

一丶WebService

1.新建项目

2.选择Web窗体

3.添加新建项

Web.config配置：(访问配置)

<system.web>

<webServices>

<protocols>

<add name="HttpGet" />

<add name="HttpPost" />

</protocols>

</webServices>

</system.web>

常用代码：

private void LoginTrain(string uid, string pw, string loginType, string device_uid)
        {
            StringBuilder sb = new StringBuilder();
            System.Net.WebClient WebClientObj = new System.Net.WebClient();
            System.Collections.Specialized.NameValueCollection PostVars = new System.Collections.Specialized.NameValueCollection();
            PostVars.Add("uid", uid);
            PostVars.Add("pw", pw);
            PostVars.Add("loginType", loginType);
            PostVars.Add("device_uid", device_uid);
            byte[] byRemoteInfo = null;
            try
            {
                string aurl = ConfigurationManager.AppSettings["url"];
                string url = string.Concat(aurl, "/", "index.php/api");
                byRemoteInfo = WebClientObj.UploadValues(url, "POST", PostVars);
            }
            catch (Exception)
            {
                sb.Append("{");
                sb.Append("\"Status\":\"9\"");
                sb.Append("}");
                Result(sb);
                throw;
            }
            string result = System.Text.Encoding.UTF8.GetString(byRemoteInfo);
            JObject jObject = (JObject)JsonConvert.DeserializeObject(result);
            sb.Append("{");
            sb.Append("\"Status\":\"" + jObject["code"].ToString() + "\"");
            if (jObject["code"].ToString() == "")
            {
                sb.Append(",\"Data\":" + jObject["data"].ToString());
            }
            sb.Append("}");
            Result(sb);
        }

二丶一般处理程序

前台访问：

 $.ajax({
             type: "post",
             url: "Handler1.ashx",
             data: {},
             dataType: "json",
             contentType: "application/json",
             success: function (data) {
                 alert(data);//返回的数据用data.d获取内容   
             },
             error: function (err) {
                 alert(err);
             }
         });
