Jquery sending a json with post

i have a flask server that take a json formatted as a string and return it (just for testing purposes) wich works when i send the request via curl like this:

curl  -X POST -d data='{"username":"xyz","password":"xyz"}' http://localhost:5000/raw_query

but when i try with this simple jquery script:

    $.post("http://127.0.0.1:5000/raw_query", '{"username":"xyz","password":"xyz"}', function(data, textStatus) {
        if(textStatus == 'success')
        {
            console.log(data)
        }
        else
        {
            console.log(textStatus)
        }
    });

i get a 400 bad request error:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>

to add more detail: this is the flask code that executes the request:

@app.route('/raw_query', methods = ['POST'])
   def raw_query():
     data = json.loads(request.form['data'])
     return jsonify(data)

i really can't think of a possible reason for it, but then again i'm quite a rookie with jq so probably i'm missing something... any help would be much appreciated

The problem is that you're not sending the parameter name data. You're just sending the JSON string as the raw parameter, not the value of the data POST parameter.

$.post("http://127.0.0.1:5000/raw_query", {
    data: '{"username":"xyz","password":"xyz"}'
}, function(data, textStatus) {
if(textStatus == 'success')
    {
        console.log(data)
    }
    else
    {
        console.log(textStatus)
    }
});

Try alter a bit your code as in the below example (have not tested this). Format your data (A plain object or string that is sent to the server with the request) like:

 $.post("http://localhost:5000/raw_query", {data:JSON.stringify({username:"xyz",password:"xyz"})}, function(data, textStatus) {
        if(textStatus == 'success')
        {
            console.log(data)
        }
        else
        {
            console.log(textStatus)
        }
    });
