關于應用模塊頁面的生成
應用模塊頁面函數
如：
public partial class userblog : BaseJsonMode{
[ModeMethod("{CanNoLogin:true,CanEnable:true}")]
static public ReturnJson index(HttpContext ctx, Object m_Parame)
{
ReturnJson m_ReturnJson = new ReturnJson();
try
{
Hashtable m_PageHH = new Hashtable();
//獲得頁面參數
JsonHelper.OBJToHashTable(m_Parame, m_PageHH);
m_ReturnJson.bOK=true;
//獲得渲染頁面的內容，傳遞頁面數據m_PageHH
m_ReturnJson.m_ReturnOBJ = RenderPageView(ctx, m_JsonModePath, "index", m_PageHH);
}
catch(Exception)
{
m_ReturnJson.bOK=false;
m_ReturnJson.sMsg="渲染頁面異常";
}
return m_ReturnJson;
}
通過瀏覽器訪問該頁面
http://../userblog/index.aspx?a=a
其中m_PageHH將獲得參數
string a=m_PageHH["a"].ToString();
渲染頁面函數
static protected string RenderPageView(HttpContext m_ctx, string m_ModePath, string m_TamplateCTL, Object m_Model)
m_ModePath：頁面文件所在位置一般為m_JsonModePath
如是渲染PC端頁面一般為Viewamazeuizh-CNindex.aspx
如是渲染手機端頁面一般為Viewdeviceamazeuizh-CNindex.aspx
我們也可以自己再加自己的路徑
如m_ModePath設置為m_JsonModePath+“/xn”;
那么找到的頁面路徑則為
如是渲染PC端頁面一般為Viewamazeuizh-CNxnindex.aspx
如是渲染手機端頁面一般為Viewdeviceamazeuizh-CNixnndex.aspx
路徑分解
對于PC端：View+UI庫名+語言+添加路徑+頁面文件
對于手機端：View+device+UI庫名+語言+添加路徑+頁面文件
我們采用aspx作為頁面模板的原因，因為ASP.NET開發人員對于aspx頁面嵌套服務端邏輯代碼是比較熟悉的，便于很快上手
對于aspx模板頁面派生自
XNWebEngine.JsonBase.MyBasePageView
典型代碼如下：
<%@ Page Language="C#" AutoEventWireup="true" Inherits="XNWebEngine.JsonBase.MyBasePageView" %>
<%@ Assembly Name="CoreSYS" %>
<%@ Import Namespace="XNWebEngine.JsonBase" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="CoreSYS" %>
<%@ Import Namespace="System.Collections.Generic" %>
<%@ Import Namespace="XNWebEngine" %>
<script language="C# " runat="server">
public Object getModel()
{
return this.Model;
}
</script>
其中getModel()獲得RenderPageView傳過來的頁面數據
如：
<%
Hashtable m_PageHH=(Hashtable)getModel();
string a="";
try
{
if(m_PageHH.ContainsKey("a"))
{
a=m_PageHH["a"].ToString();
}
}
catch
{
}
%>
后續的代碼和正常的aspx頁面寫法一致
MyBasePageView的類函數可在頁面使用的可見之前的章節
MyBasePageView常用函數和參數
獲得文件上傳參數
static public OneUpFileWEB GetUpFileURL(HttpContext ctx)
讀取cookie
static protected string ReadCookie(HttpContext ctx, string name)
static protected HttpCookie GetCookie(HttpContext ctx, string sKey)
獲得當前登錄信息
protected SessionLink GetSessionLink()
判斷當前用戶權限
public bool HavePower(string ClassFullName, string FunctionName, bool bClient, out string sError)
判斷指定角色權限
public bool HavePower(string sys_js_uuid, string username, string ClassFullName, string FunctionName, bool bClient, out string sError)
調用指定應用模塊函數
public bool CallModeFunction(string classfullname, string functionname, object m_InParame, out object m_OutParame, out string sError)
執行指定模塊的函數返回html
public string RenderModeHTML(string classfullname, string functionname, object m_InParame)
保存cookie
protected bool SaveCookie(string name, string value)
讀取cookie
protected string ReadCookie( string name)
#region 讀寫Cache
protected bool SaveCache<T>(string sKey, T m_T,bool bSlidTime=true)
protected bool ReadCache<T>(string sKey, out T m_T, int nDelayMinute = -1)
protected bool SaveCache<T>(string sKey, T m_T, TimeSpan m_nOverTime, bool bSlidTime=true)
protected bool ClearCache(string sKey)
#endregion
#region 清除cookie
protected void ClearCookie(string sKey)
#endregion
其他
protected bool SaveCookie( string name, string value, TimeSpan m_T)
protected bool SaveUserShareCache<T>(string sKey, T m_T, bool bSlidTime=true)
protected bool SaveUserShareCache<T>(string sKey, T m_T, TimeSpan m_nOverTime, bool bSlidTime=true)
protected bool ReadUserShareCache<T>(string sKey, out T m_T, int nDelayMinute = -1)
protected bool ClearUserShareCache<T>( string sKey)
protected bool SaveUserCache<T>(string sKey, T m_T, bool bSlidTime=true)
protected bool SaveUserCache<T>(string sKey, T m_T, TimeSpan m_nOverTime, bool bSlidTime=true)
protected bool ReadUserCache<T>(string sKey, out T m_T, int nDelayMinute = -1)
protected bool ClearUserCache<T>(string sKey)
讀取key
static protected string GetConfigKeyString(string sKeyName)
獲得資源url
static protected string GetResourceUrl(HttpContext ctx)
獲得頁面前綴
static protected string GetUrlBefore(HttpContext ctx)
protected static string GetUrlHead(HttpContext ctx)
判斷是否是PC端
protected bool IsPCClient()
判斷是否HTTPS
protected bool IsHTTPS()
以上函數在頁面里都可調用
常用功能及函數為
1.獲得頁面數據
<script language="C# " runat="server">
public Object getModel()
{
return this.Model;
}
</script>
<%
Hashtable m_HH=(Hashtable)getModel();
%>
2.權限判斷
<%
string sError;
if (HavePower("CodeFactory_0_base", "Addcode_adcodes", false, out sError))
{
}
%>
3.獲得當前登錄信息
<%
SessionLink m_SessionLink = GetSessionLink();
%>
4.獲得應用模塊的view Url路徑
<%
string ModeUrl = urlBefore + MainViewPath;
%>
<script src="<%=ModeUrl%>amazeui/public/js/clipboard.min.js" type="text/JAVAscript"></script>
5.獲得資源的URL路徑
<%
GetResourceUrl(HttpContext.Current);
%>
//應用例子
<script src="<%=GetResourceUrl(HttpContext.Current)%>/public/amazeui/amazeui/js/jquery.min.js"></script>
6.獲得頁面前綴
<%
GetHeadUrl(HttpContext.Current);
%>
//應用例子
ar options = {
iniUrl: "<%=GetUrlHead(HttpContext.Current)%>
weixin/initLayUI_RawJson.ajax", // 初始化接口
clearUrl: "<%=GetUrlHead(HttpContext.Current)%>
weixin/clearLayUI_RawJson.ajax", // 緩存清理接口
renderPageVersion: true, // 初始化頁面是否加版本號
bgColorDefault: false, // 主題默認配置
multiModule: true, // 是否開啟多模塊
menuChildOpen: false, // 是否默認展開菜單
loadingTime: 0, // 初始化加載時間
pageAnim: true, // 切換菜單動畫
};
頁面渲染函數的內部實現
static protected string RenderPageView(HttpContext m_ctx, string m_ModePath, string m_TamplateCTL, Object m_Model)
該頁面渲染函數支持對aspx的渲染和shtml采用開源JNTemplate渲染
aspx頁面渲染核心代碼
//構建Page pageVirtualPath:aspx文件路徑
Page handler = BuildManager.CreateInstanceFromVirtualPath(pageVirtualPath, typeof(System.Web.UI.Page)) as Page;
//設置頁面數據
SetPageModel(handler, m_Model, ViewPath);
StringWriter output = new StringWriter();
//執行輸出頁面
m_ctx.Server.Execute(handler, output, false);
//返回頁面字符串
return output.ToString();
shtml頁面JNTemplate渲染核心代碼
string output="";
using (JNTemplateEngine m_JNTemplateEngine = new JNTemplateEngine(m_ctx, m_ModePath, FName, m_Model, true))
{
m_JNTemplateEngine.Render(out output);
}
對于開源JNTemplate的使用可查閱相關資料

使用JNTemplate的頁面例子
頁面函數：
static public ReturnJson uniAppTestPage(HttpContext ctx, Object m_Parame)
{

JsonHelper.OBJToHashTable(m_Parame, m_HH);
ReturnJson m_ReturnJson = new ReturnJson();
try

string type = "";
if (KeyIsOK(m_HH, "type"))
{
type = m_HH["type"].ToString();
}
m_ReturnJson.bOK = true;
oneData m_oneData = new oneData();
m_oneData.m_HH = new Hashtable();
m_oneData.A = "1";
m_oneData.B = 2;
m_oneData.m_HH["A"] = type;
m_oneData.m_oneData = new oneData();
m_oneData.m_oneData.m_HH = new Hashtable();
m_oneData.m_oneData.A = "11";
m_oneData.m_oneData.B = 22;
m_oneData.m_oneData.m_HH["A"] = "下級測試數據";
oneData m_oneData0 = new oneData();
m_oneData0.A = "c1";
m_oneData.m_HH["m_oneData"] = m_oneData0;//錯誤Hashtable內只能包含基本數據類型如int string float double 不能包含對象否則模板訪問失敗
int i;
List<Hashtable> m_HHList = new List<Hashtable>();
for (i = 0; i < 10; i++)
{
Hashtable m_oneHH = new Hashtable();
m_oneHH["pos"] = i;
m_HHList.Add(m_oneHH);
}
m_oneData.m_oneData.m_HHList = m_HHList;
List<oneRow> m_RowArray = new List<oneRow>();
for (i = 0; i < 10; i++)
{
oneRow m_oneRow = new oneRow();
m_oneRow.pos = i;
m_RowArray.Add(m_oneRow);
}
m_oneData.m_oneData.m_HH["array"] = m_RowArray.ToArray();
m_oneData.m_oneData.m_HH["array2"] = m_HHList;
m_oneData.m_oneData.m_RowArray = m_RowArray;
m_ReturnJson.m_ReturnOBJ = RenderPageView(ctx, m_JsonModePath, "uniappTestPage.shtml", m_oneData,typeof(menuClass));
}
catch
{
m_ReturnJson.bOK = false;
m_ReturnJson.sMsg = "渲染uniappTestPage失敗";

}
uniappTestPage.shtml的頁面內容純測試模板語法所以里面未出現html標簽
m_oneData.A:${model.A},m_oneData.B:${model.B},m_oneData.m_HH["A"]:${model.m_HH["A"]},m_oneData.m_oneData.A:${model.m_oneData.A},m_oneData.m_oneData.B:${model.m_oneData.B},m_oneData.m_oneData.m_HH["A"]:${model.m_oneData.m_HH["A"]},m_SessionLink.username:${engine.GetSessionLink().username}
權限判斷：CoreSYS.SYS/AddCompany:${if(engine.HavePower("CoreSYS.SYS","AddCompany"))}有權限執行${else}無權限執行${end}
對象列表數據:${foreach(one in
model.m_oneData.m_RowArray)}序號-${one.pos} ${end}<br />
Hashtable的List列表數據:${foreach(one in model.m_oneData.m_HHList)}序號-${one["pos"]} ${end}</br>
Hashtable中對象${model.m_HH["m_oneData"]}</br>
引號內</br>
Hashtable的List列表數據:"${foreach(one in model.m_oneData.m_HHList)}序號-${one["pos"]} ${end}"</br>
模板頁內變量使用<br />
${set(a=123)}<br />
輸出:${a}
<br />
<ul>
定義ii變量
${set(ii=0)}
${for(ii=1;ii<4;ii++)}
<li>${ii}</li>
${end}
</ul>
</br>
復雜語法測試<br />
${set(m_SessionLink=engine.GetSessionLink())}
${if(model.m_oneData.m_HH.ContainsKey("BB"))}
有BB
${else}
無BB
${end}
<br />
復雜測試
Hashtable對象${set(m_oneData=model.m_HH["m_oneData"])}
${set(hh=engine.OBJToHashTable(m_oneData))}
${hh["A"]}
<br />
Hashtable對象
${engine.OBJToHashTable(model.m_HH["m_oneData"])["A"]}
<br />
Hashtable包含Hashtable數組
${set(m_List=model.m_oneData.m_HH["array2"])}
${set(m_HHList=engine.OBJToListHashtable(m_List))}
${foreach(rr in m_HHList)}
${rr["pos"]},
${end}
<br />
Hashtable包含Hashtable數組
${foreach(rr2 in engine.OBJToListHashtable(model.m_oneData.m_HH["array2"]))}
${rr2["pos"]},
${end}
