Python and Youpaiyun interface docking tutorial: implementing audio synthesis function

Tutorial on interfacing Python with Youpaiyun interface: Implementing audio synthesis function

1. Introduction:
Youpaiyun is a cloud computing service provider that provides a wealth of cloud storage, image processing, Audio and video processing and other services. This tutorial will introduce how to use Python to connect with Youpaiyun interface to implement audio synthesis function.

2. Preparation:

1. Register a Youpaiyun account and create a service space. Obtain the bucket name, operator name and operator password of the service space.
2. Install dependent libraries: requests, pycryptodome, base64, json.

3. Implementation steps:

1. Import dependent libraries.

import requests
import json
import base64
from Crypto.Cipher import AES
from Crypto.Util.Padding import pad

2. Define the URL of the audio file and the URL of the background music to be synthesized.

audio_url = 'http://your-audio-url.com/audio.mp3'
background_music_url = 'http://your-background-music-url.com/bg_music.mp3'

3. Define the parameters required for the Youpai Cloud interface.

bucket_name = 'your-bucket-name'
operator_name = 'your-operator-name'
operator_password = 'your-operator-password'
template_name = 'your-template-name'
save_as = '/save/as/save.mp3'

4. Define the URL of the cloud interface.

api_url = f'http://v0.api.upyun.com/{bucket_name}/template/{template_name}'

5. Define encryption function for encrypting audio.

def encrypt(content, key):
    cipher = AES.new(key, AES.MODE_ECB)
    encrypted = cipher.encrypt(pad(content, AES.block_size))
    return base64.b64encode(encrypted).decode('utf-8')

6. Define the send request function, which is used to send synthesis requests to Youpaiyun.

def send_request(payload):
    auth = f'{operator_name}:{operator_password}'
    headers = {
        'Content-Type': 'application/json',
        'Authorization': f'Basic {base64.b64encode(auth.encode()).decode()}'
    }
    response = requests.post(api_url, headers=headers, data=json.dumps(payload))
    return response.json()

7. Define the main function to complete the audio synthesis function.

def main():
    audio_content = requests.get(audio_url).content

    payload = {
        'status': 'success',
        'audio': audio_content,
        'audio_encrypt': encrypt(audio_content, operator_password.encode())
    }

    response = send_request(payload)
    task_id = response['task_id']

    print(f'合成任务已提交，任务ID为：{task_id}')

    while True:
        check_payload = {'task_id': task_id}
        check_response = send_request(check_payload)
        status = check_response['status']

        if status == 'processing':
            print('任务正在处理...')
        elif status == 'success':
            result_url = check_response['result']
            print(f'合成任务已成功完成，合成结果保存在：{result_url}')
            break
        else:
            error_message = check_response.get('message', '合成任务失败')
            print(error_message)
            break

8. Execute the main function.

if __name__ == '__main__':
    main()

4. Summary:
Through this tutorial, we learned how to use Python and Youpaiyun interface to implement the audio synthesis function. First, we need to prepare the account and service space of Youpaiyun, then import the relevant dependency libraries and define the required parameters and API interface URL. Next, we define the encryption function and send request function to encrypt the audio and send the synthesis request. Finally, the audio synthesis function is implemented by calling the main function. Hope this tutorial is helpful to everyone!
