Ответ №1:

Похоже, что приложение подключается к контейнеру без проблем, но при запуске происходит сбой. Я не совсем уверен, почему происходит сбой при попытке получить ваш домашний URL-адрес ‘/’.

Что касается проблемы с значком, приведенный ниже код помогает flask находить статические ресурсы и может помочь запуску приложения.

 from flask import send_from_directory,


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


@app.route('/return', methods=['POST'])
def getvalue():
    letexte = request.form['letexte']
    user_input = request.form['user_input']
    user_title = request.form['user_title']
    input_two = request.form['input_two']
    
    lowercase_words = letexte.lower()
    
    tokenized = word_tokenize(lowercase_words)
    words = len(lowercase_words.split(' '))
    sentences = sent_tokenize(letexte)
    no_sent = len(sentences)
    
    def count_unique_words(text_string):
        word_list = re.split('; |, |*|n |s', text_string)
        return list(dict.fromkeys(word_list))
    uniq_words = len(count_unique_words(letexte))
    
    nouns = []
    list_most_occur = []
    for w in tokenized:
        if len(w) > 2 and w[0]:
            nouns.append(w)
    
    counter_variables = Counter(nouns)
    most_occur = counter_variables.most_common(10)
    
    for mo in most_occur:
        list_most_occur.append(mo)
        
    input_count = tokenized.count(user_input)
    
    lesphrases = [ t for t in letexte.split('. ') or letexte.split('? ') or letexte.split('! ') if input_two in t]
    
    return render_template('return.html',ut=user_title, ltxt=letexte, w=words, uw=uniq_words, s=no_sent, lmo=list_most_occur,ui=user_input, ic=input_count, it=input_two, lp=lesphrases)


@app.route('/favicon.ico')
def favicon():
    return send_from_directory(os.path.join(app.root_path, 'static'), 
        'favicon.ico', mimetype='image/vnd.microsoft.icon')

1. я добавил свой код на python. может быть, у меня будет лучшее представление о том, что не так

2. Похоже, вы назначаете две разные функции одной и той же конечной точке. Измените маршрутизацию функции getvalue() на что-то вроде app.route(‘/ return’, methods=[‘POST’]). В вашей форме обновите свойство on submit, чтобы перейти к вашей новой / возвращаемой конечной точке. В настоящее время вы говорите flask делать две разные вещи, когда вы переходите на одну и ту же домашнюю страницу.

3. app.route(‘/ return’, methods=[‘POST’] не работает. я добавил свою HTML-форму, я чувствую, что она исходит оттуда…

4. Вам необходимо обновить свойство действия формы с <имя формы=»passdata» action=».». на <имя формы =»passdata» action=»/return»> . Это отправит данные формы в функцию просмотра «/ return» для обработки.

5. Потрясающе, приятно слышать! Пожалуйста, отметьте исходный вопрос решенным, чтобы другие знали, что вы нашли решение. Всегда приятно видеть развертывание приложения в реальном мире!

Ответ №2:

У меня была такая проблема. Чтобы решить ее, я должен был убедиться, что все пакеты, которые мне нужны в requirements.txt файл был успешно установлен, особенно dnspython
