为什么我的JSON脚本无法从FLASK获取JSONIFY返回？

Question

I have a route in FLASK that return a jsonify object:

@app.route('/getgoodbye', methods=['GET', 'POST'])
def getgoodbye():
    return jsonify({'html':'<h1>Good Bye</h1>'})

and a function in jscript that need get this object:

    function getgoodbye2(){
        var req = $.getJSON('/getgoodbye');
        alert(req);
    }

But the out of alert(req) is: [object Object]

to alert(JSON.stringify(req)): {"readyState":1}

to alert(req.html) is: undefined

How do I can acess the key and values of the dict?

Since $.getJSON works async you need to do it inside callback, I have created the JSON in myjson.com ( https://api.myjson.com/bins/9ug2k ) and here is the code snippet

 $.getJSON('https://api.myjson.com/bins/9ug2k',function(resp){ console.log(resp.html) }) 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> 

Hope it helps!
