使用httpservice与asp的伪web服务通讯，完成数据库操作
我提供一个asp的伪服务思想：
clientreq.xml:
-------------------------------------------------------------------------------------------------
<?xml version=1.0 encoding=gb2312?>
<testpacket>
<msgtype>getvaluereq</msgtype>
<version>1.0</version>
</testpacket>
index.mxml:
-------------------------------------------------------------------------------------------------
<mx:model id=mreq source=clientreq.xml/>
<mx:httpservice id=hs url=http://asp/testserver.asp
resultformat=xml
method=post
contenttype=application/xml
showbusycursor=true>
<mx:request>
<xml>{mreq}</xml>
</mx:request>
</mx:httpservice>
testserver.asp:
-------------------------------------------------------------------------------------------------
主要有获得数据包，解析数据包，指定操作，返回数据四步
1。获得提交的数据包
set odom = server.createobject(msxml2.domdocument)
odom.load request
2。解析数据包，获得msgtype
smsgtype = trim(odom.selectsinglenode(//msgtype).text)
select case smsgtype
case getvaluereq
call getvalue
'case deletevaluereq
' call deletevalue
case insertvaluereq
' call insertvalue(odom)
'case updatevaluereq
' call updatevalue
'else case
' call showerrmsg
end select
3。指定操作，此处完成getvalue操作，其中有很多可以做成公共的模块供其他函数使用
sconn = driver={microsoft access driver (*.mdb)};dbq= & server.mappath(message.mdb)
set oconn = server.createobject(adodb.connection)
oconn.open sconn
ssql = select * from message order by id desc
set ors = server.createobject(adodb.recordset)
ors.open ssql, oconn, 1, 1
'构造无记录xml文档
if ors.eof and ors.bof then
sxml = <?xml version=1.0 encoding=gb2312?> & vbcrlf &_
<testpacket> & vbcrlf &_
<msgtype>systemresp</msgtype> & vbcrlf &_
<version>1.0</version> & vbcrlf &_
<result>0</result> & vbcrlf &_
</testpacket>
end if
'构造有记录xml文档
if not (ors.eof and ors.bof) then
do while not ors.eof
stmpxml = stmpxml & <messages> & vbcrlf &_
<name> & ors(name) & </name> & vbcrlf &_
<age> & ors(age) & </age> & vbcrlf &_
<sex> & ors(sex) & </sex> & vbcrlf &_
<msg> & ors(msg) & </msg> & vbcrlf &_
</messages> & vbcrlf
ors.movenext
loop
sxml = <?xml version=1.0 encoding=gb2312?> & vbcrlf &_
<testpacket> & vbcrlf &_
<msgtype>systemresp</msgtype> & vbcrlf &_
<version>1.0</version> & vbcrlf &_
<result>1</result> & vbcrlf & stmpxml &_
</testpacket>
end if
4.返回数据
set odom = server.createobject(msxml2.domdocument)
odom.loadxml(sxml)
odom.save(response)
set odom = nothing
message.mdb
-------------------------------------------------------------------------------------------------
数据库名：message.mdb
数据表名：message
数据字段：字段 类型
id 自动编号
name 文本
age 数字
sex 文本
msg 备注
执行结果：
-------------------------------------------------------------------------------------------------
我是设置httpservice的resultformat=text时，看显示的结果
