wcf 多文件上传
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
