app.py code:

from flask import Flask, render_template, request, jsonify
app = Flask(__name__)

@app.route('/')
def home():
   return render_template('index.html')

@app.route('/test', methods=['GET'])
def test_get():
   title_receive = request.args.get('title_give')
   print(title_receive)
   return jsonify({'result':'success', 'msg': '이 요청은 GET!'})

if __name__ == '__main__':
   app.run('0.0.0.0',port=5000,debug=True)

index.html code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <script>
        function hey(){
            $.ajax({
    type: "GET",
    url: "/test?title_give=봄날은간다",
    data: {},
    success: function(response){
       console.log(response)
    }
  })
        }
    </script>
</head>
<body>
    <h1>버튼을 만들자</h1>
<button>버튼을 만들자</button>
</body>
</html>

이렇게 했는데

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.

To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

이런식으로 http://localhost:5000을 치니 위에 오류가 나네요ㅠㅠ
