Data telah berjaya disimpan dalam server.py, tetapi ralat 404 tidak ditemui berlaku semasa cuba mendapatkannya.

Saya menulis fail server.py yang boleh menyimpan nama pelajar, nombor indeks dan gred purata. Apabila saya menjalankan fail client.html dan masukkan data dan klik tambah pelajar, ia mengatakan pelajar telah berjaya ditambahkan, tetapi apabila saya memasukkan indeksnya untuk menggunakan fungsi dapatkan pelajar, ia mengatakan 404 Pelajar Tidak Ditemui.

Ini ialah kod fail server.py:

from flask import Flask, request, jsonify
import pickle

app = Flask(__name__)

try:
    with open('students.pickle', 'rb') as f:
        students = pickle.load(f)
except FileNotFoundError:
    students = {}

@app.route("/")
def index():
    with open("client.html") as f:
        return f.read()

@app.route('/add_student', methods=['POST'])
def add_student():
    name = request.form.get('name')
    surname = request.form.get('surname')
    index = request.form.get('index')
    grade = request.form.get('grade')
    students[index] = {'name': name, 'surname': surname, 'index': index,'grade': grade}

    with open('students.pickle', 'wb') as f:
        pickle.dump(students, f)
        
    return jsonify(message='Student added successfully'), 201

@app.route('/get_student/<int:index>', methods=['GET'])
def get_student(index):
    student = students.get(index)
    if student:
        return jsonify(student)
    else:
        return 'Student not found', 404

if __name__ == '__main__':
    app.run(host='localhost', port=8000, debug=True)

Ini ialah kod fail client.html:
