请问大神jsoup怎么模拟这个ajax提交

[frost988]

我想用jsoup模拟这个ajax提交，但是一直提示提交参数有问题，请大神帮忙看看怎么用jsoup模拟，就是data那儿一直没搞懂
ajax的写法如下：
$.ajax({type: "POST",
url: baseUrl+"/cathectic/betNum.php?m=lottery&c=index&a=sendCode&rand="+Math.random()+"&lottery_type="+lottery_type,
data:"playType="+pt+'&zhushu='+zhushu+'&proName='+proName+'&totals='+totals+'&codes='+encodeURIComponent(codes),
dataType: "json" ,
cache : false,
success: function(json){

jsoup写法如下：
Connection conn = mRequestHelper.getConnection(AppConfig.tz_URL);
conn.data("playType", "HZ");
conn.data("zhushu", "1");
conn.data("proName", "82231");
conn.data("totals", "5");
conn.data("codes", "%E5%8F%8C%7CHZ%7C%E5%92%8C%E5%80%BC%7C5%7C9.5%3Cwaf%3E");
Document doc = mRequestHelper.post(conn);
