VBScript 是 ASP 服务端程序的常用语言,VBScript 解析 JSON是个问题.,自己写解析程序不太容易,碰到这问题, 第一个想到的就是 JScript 了。 注意,以下文件均以UTF-8的编码保存! 方法一(这是直接在 asp 里混用脚本): - <script language="jscript" runat="server">
- Array.prototype.get = function(x) { return this[x]; };
- function parseJSON(strJSON) { return eval("(" + strJSON + ")"); }
- </script>
- <%
- Dim json, obj
- json = "{a:""aaa"", b:{ name:""bb"", value:""text"" }, c:[""item0"", ""item1"", ""item2""]}"
- Set obj = parseJSON(json)
- Response.Write "JSON原文为:<br>"
- Response.Write json
- Response.Write "<hr>"
- Response.Write "a=" & obj.a & "<br />"
- Response.Write "b=" & obj.b.name & "<br />"
- Response.Write "c.length=" & obj.c.length & "<br />"
- Response.Write "c.get(0)=" & obj.c.get(0) & "<br />"
- Set obj = Nothing
- %>
复制代码还有一个方法就是 使用 MS 的 脚本控件,也一样是使用了 JScript 方法二:
解析文件:paseJSON.asp - <%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
- <%Session.CodePage="65001"%>
- <%Response.CodePage="65001"%>
- <%Response.Charset="UTF-8" %>
- <%
- Dim scriptCtrl
- Function parseJSON(str)
- If Not IsObject(scriptCtrl) Then
- Set scriptCtrl = Server.CreateObject("MSScriptControl.ScriptControl")
- scriptCtrl.Language = "JScript"
- scriptCtrl.AddCode "Array.prototype.get = function(x) { return this[x]; }; var result = null;"
- End If
- scriptCtrl.ExecuteStatement "result = " & str & ";"
- Set parseJSON = scriptCtrl.CodeObject.result
- End Function
- %>
复制代码测试文件:c.asp - <!--#include file="jsonParse.asp"-->
- <%Session.CodePage="65001"%>
- <%Response.CodePage="65001"%>
- <%Response.Charset="UTF-8" %>
- <%
- Dim json
- json = "{a:""aaa"", b:{ name:""bb"", value:""text"" }, c:[""item0"", ""item1"", ""item2""]}"
- Set obj = parseJSON(json)
- Response.Write "JSON原文为:<br>"
- Response.Write json
- Response.Write "<hr>"
- Response.Write "a=" & obj.a & "<br />"
- Response.Write "b=" & obj.b.name & "<br />"
- Response.Write "c.length=" & obj.c.length & "<br />"
- Response.Write "c.get(0)=" & obj.c.get(0) & "<br />"
- Set obj = Nothing
- %>
复制代码方法一和方法二执行结果:
ASP解析JSON格式数据方法
上面的方法应该是最简洁的方法了。 方法三: JSON解析文件----jsonParse.asp: - <%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
- <%Session.CodePage="65001"%>
- <%Response.CodePage="65001"%>
- <%Response.Charset="UTF-8" %>
- <%
- 'Option Explicit
- Dim sc4Json
- Sub InitScriptControl
- Set sc4Json = Server.CreateObject("MSScriptControl.ScriptControl")
- sc4Json.Language = "JavaScript"
- sc4Json.AddCode "var itemTemp=null;function getJSArray(arr, index){itemTemp=arr[index];}"
- End Sub
- Function getJSONObject(strJSON)
- sc4Json.AddCode "var jsonObject = " & strJSON
- Set getJSONObject = sc4Json.CodeObject.jsonObject
- End Function
- Sub getJSArrayItem(objDest,objJSArray,index)
- On Error Resume Next
- sc4Json.Run "getJSArray",objJSArray, index
- Set objDest = sc4Json.CodeObject.itemTemp
- If Err.number=0 Then Exit Sub
- objDest = sc4Json.CodeObject.itemTemp
- End Sub
- %>
复制代码测试文件----Test.asp - <!--#include file="jsonParse.asp"-->
- <%Session.CodePage="65001"%>
- <%Response.CodePage="65001"%>
- <%Response.Charset="UTF-8" %>
- <%
- Dim strTest
- strTest = "{name:""张三丰"", age:24, email:[""zsf@163.com"",""zsf@gmail.com""], family:{parents:[""父亲"",""母亲""],toString:function(){return ""家庭成员"";}}}"
- Response.Write "JSON原文:<br>"
- Response.Write ( strTest )
- Dim objTest
- InitScriptControl
- Set objTest = getJSONObject( strTest )
- %>
- <hr>
- 姓名:<br>
- <%=objTest.name%><br>
- <hr>
- 邮件地址(方法一):<br>
- <%
- For i=0 To objTest.email.length
- Response.Write ( sc4Json.Eval("jsonObject.email["&i&"]") & "<br>")
- Next
- %>
- 邮件地址(方法二):<br>
- <%
- Dim email
- For i=0 To objTest.email.length
- getJSArrayItem email,objTest.email,i
- Response.Write email & "<br>"
- Next
- %>
- <hr>
- 家庭信息:<br>
- <%
- Dim ai
- For i=0 To objTest.family.parents.length
- getJSArrayItem ai, objTest.family.parents, i
- Response.Write ai & "<br>"
- Next
- %>
- toString()函数:<br>
- <%=objTest.family.toString()%>
- <br>
- toString属性:<br>
- <%=objTest.family.toString%>
- <%
- Set objTest=nothing
- %>
复制代码方法三执行行结果:
