用 groovy post 数据到页面

下面的代码修改url， vars之后可以直接运行 def encode = 'utf8'; def url = '...' //TODO: change here! def vars = [uid,'12345',name:'myname'] //TODO: change here! def en = {k,v->    return URLEncoder.encode(k,encode) + "=" + URLEncoder.encode(v,encode); } def post = {         URLConnection conn = new URL(url).openConnection();         conn.setDoOutput(true);        // ((HttpURLConnection)conn).setRequestMethod( "POST");         OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream(),encode);         def vs = new StringBuilder();         vars.eachWithIndex(){k,v,no->             if(no>0){                 vs.append('&');             }             vs.append(en(k,v));         }         //println("getUrl=" + url + "?" + vs.toString());         wr.write(vs.toString());         wr.flush();             def r = new InputStreamReader(conn.getInputStream(),encode).text         return r; }; def ret = post(); println ("ret=" + ret) def records = new XmlParser().parseText(ret) //println( records.code.text() ) // access xml // records.code.text()...
