使用枪鱼酒时烧瓶超时

Question

我有一个将音频文件转换为文本的应用。使用烧瓶和烧瓶socketio。当我使用“ python run.py”运行它时，它可以完美运行，但是当我使用：“ gunicorn -k eventlet -b 0.0.0.0:5000 run：app”运行它时，它将在调用谷歌的那部分停止在audio.py文件中对文本api进行语音转换。

这些是当前的当前代码。

run.py：

from ats import socketio, app, db

if __name__ == '__main__':
    db.create_all()
    socketio.run(app, host='0.0.0.0', port=5001, debug=True)

init。py

import logging, json

from flask import Flask, jsonify, render_template, request
from flask_socketio import SocketIO, emit, send
from flask_cors import CORS
from flask_sqlalchemy import SQLAlchemy
from flask_marshmallow import Marshmall

app = Flask(__name__, instance_relative_config=True, static_folder="templates/static", template_folder="templates")

# Create db instance
db = SQLAlchemy(app)
ma = Marshmallow(app)

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

# import models
from ats import models

# set up CORS
CORS(app)
socketio = SocketIO(app, cors_allowed_origins='*', async_mode='eventlet')


# import blueprints
from ats.product.product import product_blueprint

# register blueprints
app.register_blueprint(product_blueprint, url_prefix='/api/product')

product_blueprint = Blueprint('product', __name__)

@product_blueprint.route('/add', methods=['post'])
def addProduct():
    try:
        data = request.form

        foldername = data['name']
        scriptFile = request.files['script']
        audioFile = request.files['audio']

        # save the script and audio file to uploads folder
        FILE.createFolder(foldername)
        FILE.save(foldername, scriptFile)
        FILE.save(foldername, audioFile)

        # list the files in the uploads
        audioFiles = FILE.getAudioFileList(foldername)

        fileCount = len(audioFiles)
        currentFile = 1
        # ============ speech to text =============
        for file in audioFiles:
            recognizedText = AUDIO.convert(foldername, file)

            }
            Audio.add(newAudio)

            # emit event to update the client about the progress
            percent = math.floor((currentFile / float(fileCount) ) * 100) 
            emit('upload_progress', {'data': percent}, room=data['sid'], namespace='/')
            eventlet.sleep()
            currentFile += 1

        # Delete the files in uploads folder
        FILE.delete(foldername)

        return jsonify({'data': None, 'message': 'Product was added.', 'success': True}), 200
    except Exception as e:
        abort(500, str(e))

# Instantiates a client
client = speech.SpeechClient()

def convert(foldername, filename):
    try:

        file = os.path.join(app.config['UPLOAD_FOLDER'], foldername, filename)

        # Loads the audio into memory
        with io.open(file, 'rb') as audio_file:
            content = audio_file.read()
            audio = types.RecognitionAudio(content=content)

        config = types.RecognitionConfig(
            encoding=enums.RecognitionConfig.AudioEncoding.LINEAR16,
            sample_rate_hertz=48000,
            language_code='ja-JP')

        # Call speech in the audio file
        response = client.recognize(config, audio) # The code will stop here, that results to worker timeout in gunicorn

        return response
    except Exception as e:
        raise e

我一直在寻找解决方案将近一个星期，但仍然找不到。谢谢您的帮助。
