sorry about my wrong description about the ajax which from different
browsers
my chrome and firefox can successfully use ajax to post data to node.js
but ie9 and ie8 can't and server will receive empty body like {}
this is my response header
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");
res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
res.header("X-Powered-By",' 3.2.1')
res.header("Content-Type", "application/json;charset=utf-8");
if(req.method==='OPTIONS')
res.send(200);
else
next();
});
and we sure we have no cross origin problem
so is there any possible ajax wrong or node.js setting needed to adjust?
and thanks a lot john~
