最後還是用superagent的方法解決了

var charset = require('superagent-charset'); var superagent = charset(require('superagent')); function agent(req,res){ superagent.post(url+req.path) .type('form') .send(req.body) .set('Accept', 'application/json') .charset('gbk') .end(function (err, sres) { var html = sres.text; res.send(html); }); } app.post('/list',function(req,res,next){ agent(req,res) })

後台發送資料到前端，在實例化PrintWriter物件前加上

response.setCharacterEncoding("GBK"); 然后再 PrintWriter writer=response.getWriter();
