Issue with GET forms and Node.JS and Express

Question

I've hot a very simple form in HTML, that sends GET information to my Node.JS server, with Express. This is the form:

    <form method="get" action="/search" autocomplete="off" class="navbar-search pull-left">
       <input name="search" type="text" id="search" data-provide="typeahead" placeholder="Search..." />
    </form>

And this is the server part:

app.get('/search', function (req, res){

   console.log(req.query["search"]);

   res.render('search.ejs')

});

When I write something to the input, and press enter, and the page keeps loading for a long while, and I receive a 340 error when I get in for example in http://localhost:8080/search?search=foo . I think I have a problem with the from, that doesn't send properly the values, because it doesn't work with POST request too. Any solution for this?

Thank's advance!

Answer 1

It is because you have to use the req.params.search instead of req.query which does not work.

app.get('/search', function (req, res){
   var search = req.query.search;

   console.log(search);

   res.render('search.ejs')

});

Here you can read more about it: http://expressjs.com/api.html#req.param

下次找出一个erorr，输入app.get(... console.log(res, req);并找到你的变量所在的位置。

Very interesting, for me it worked!

app.get('/search', function (req, res){
   var search = req.query;

   console.log(search, 'of type', typeof search);
   res.send("the query is about the student with name " + search.sname + ' and subject '+search.ssubject );

});

with the form

<form method= 'GET' action="/search" autocomplete="off">
            Student Name:<br>
            <input type="text" name="sname">
            <br>
            Student Subject:<br>
            <input type="text" name="ssubject">
            <br>
            <input type="submit" value="Submit">
            <input type="reset" value="Reset">
        </form>
