sql存储过程进行http post如果URL中有中文乱码问题

[xiangyueming]

--P_PM_WorkFlow_FlowDo '王磊',''
ALTER PROCEDURE [dbo].[P_PM_WorkFlow_FlowDo] (@FInstID varchar(50),@FActID varchar(50))  AS
begin
	declare @ServiceUrl as varchar(8000) 
	declare @UrlAddress varchar(500)
	declare @FMobileServiceIP varchar(100)
	declare @FMobileServicePort int
	select @FMobileServiceIP=FMobileServiceIP,@FMobileServicePort=FMobileServicePort from T_CL_GlobalSet
	set @UrlAddress = 'http://***.6*2.197.129:50000'+'/FaceView.asmx/'
	declare @FunName varchar(50)
	set @FunName = 'GetLoginResult'   
	declare @P1 varchar(50),@P2 varchar(50),@P3 varchar(50)
	set @P1 = 'username'
	set @P2 = 'password'
	set @P3 = 'devicetoken'
	set @ServiceUrl = @UrlAddress + @FunName + '?' + @P1 + '=' + @FInstID +'&' + @P2 + '=' + @FActID   +'&' + @P3 + '='           
	Declare @Object as Int
	Declare @ResponseText as Varchar(8000)
	Exec sp_OACreate 'MSXML2.XMLHTTP', @Object OUT;
	Exec sp_OAMethod @Object, 'open', NULL, 'get',@ServiceUrl,'false'
        EXEC sp_OAMethod @Object, 'setRequestHeader', NULL,'Content-Type', 'application/x-www-form-urlencoded';
	Exec sp_OAMethod @Object, 'send'
	Exec sp_OAMethod @Object, 'responseText', @ResponseText OUTPUT     
	Select @ResponseText     
	Exec sp_OADestroy @Object 
end

像上面那种写法，对http接口进行get访问，但是如果我参数中有中文，则接口那边解析会乱码（前提：接口是正常的，通过其他途径访问都一切正常），通过抓包工具发现：1、通过sql存储过程进行get访问的原始流为：/FaceView.asmx/GetLoginResult?devicetoken=&password=&username=王磊 其中的中文不会进行urlencode 2、通过其他正常能访问接口的抓包的原始流为：/FaceView.asmx/GetLoginResult?devicetoken=&password=&username=%E7%8E%8B%E7%A3%8A

这个问题要怎么破？求高手解答

可是试试在sql中进行编码 http://blog.csdn.net/zlp321002/article/details/2842980
