How to retrieve POST query parameters

Question

Here is my simple form:

<form id="loginformA" action="userlogin" method="post">
    <div>
        <label for="email">Email: </label>
        <input type="text" id="email" name="email"></input>
    </div>
<input type="submit" value="Submit"></input>
</form>

Here is my Express.js/Node.js code:

app.post('/userlogin', function(sReq, sRes){    
    var email = sReq.query.email.;   
}

I tried sReq.query.email or sReq.query['email'] or sReq.params['email'], etc. None of them work. They all return undefined.

When I change to a Get call, it works, so any idea?

Hello @kartik,

This will do it if you want to build the posted query without middleware:

app.post("/register/",function(req,res){
    var bodyStr = '';
    req.on("data",function(chunk){
        bodyStr += chunk.toString();
    });
    req.on("end",function(){
        res.send(bodyStr);
    });

});

That will send this to the browser

email=emailval&password1=pass1val&password2=pass2val

It's probably better to use middleware though so you don't have to write this over and over in each route.

Hope it helps!!

Thank you!!
