Tsung替换动态变量中的字符

Question

运用

 <dyn_variable name="OK_Button" jsonpath="test.items[0].links[0].href"/>

我能够从json http://localhost:8081/mycode/1.5.0/extended/call/action提取以下网址

但是，在下一个请求中，我想通过更改IP和端口来使用上述url

例如：

<dyn_variable name="ok_button" jsonpath = "test.items[0].links[0].href"/>
<setdynvars sourcetype="eval"
        code='fun({Pid,DynVars})->
                  {ok,Val}=ts_dynvars:lookup(ok_button,DynVars),
                  L1 = re:replace(Val,"localhost","192.169.1.100",[{return,list}]),
                  L2 = re:replace(L1,"8801","8800",[{return,list}]),
                  L2 end.'>
    <var name="new_address" />
</setdynvars>

%% ok_button tolower
%% L2 = "http://192.169.1.100:8800/mycode/1.5.0/extended/call/action"

<request subst="true">
     <http url="%%_new_address%%" method="POST" contents="......."
</request>
