How to use Python to connect to Youpaiyun interface to implement video encryption function

Youpaiyun is a company that provides cloud storage services. They provide a rich API interface to facilitate developers to upload and download files. , management and other operations. In actual application scenarios, sometimes we need to encrypt videos to protect the security of the videos. This article will introduce how to use Python to connect to the cloud interface to implement video encryption.

First of all, we need to register an account on Youpaiyun official website and create a service to obtain relevant information about the API interface. The specific steps are as follows:

1. Log in to Youpaiyun official website (https://console.upyun.com/).
2. Register an account and log in.
3. Click "Create Service" and fill in the corresponding service information.
4. After the service is successfully created, enter the service details page and copy the service name, operator name, operator password and other relevant information. We will use this information in the code.

Next, let’s write Python code. First, we need to install the requests library for sending HTTP requests. You can use the following command to install:

pip install requests

The following is a simple code example for uploading video files to Youpai Cloud and encrypting the video:

import requests
import hashlib
import time

# 又拍云服务相关信息
service = 'your_service_name'
operator = 'your_operator_name'
password = 'your_operator_password'

# 加密视频的密钥
encrypt_key = 'your_encrypt_key'

# 文件路径
file_path = '/path/to/your/video.mp4'

# 获取当前时间戳
timestamp = str(int(time.time()))

# 计算签名
signature = hashlib.md5((password + '&' + timestamp).encode('utf-8')).hexdigest()

# 构建上传文件的URL
upload_url = f'https://v0.api.upyun.com/{service}'

# 构建请求头部信息
headers = {
    'Authorization': f'UPYUN {operator}:{signature}',
    'X-Date': timestamp,
    'X-Encrypt-Key': encrypt_key
}

# 上传视频
with open(file_path, 'rb') as file:
    files = {'file': file}
    response = requests.post(upload_url, headers=headers, files=files)
    print(response.text)

In the above code , we first obtain the required information based on the API document provided by Youpai Cloud, including the name of Youpai Cloud service, the operator's name and password, and the key required to encrypt the video. Then, we specify the path of the video file to be uploaded and get the current timestamp.

Next, we use the hashlib library to encrypt the operator password and timestamp to generate a signature for authentication. We then construct the URL to upload the file, specifying request headers that include our authentication information and the key to encrypt the video.

Finally, we use the requests library to send a POST request and upload the video file to Youpaiyun. After the upload is successful, Youpaiyun will return a response in JSON format, which we can print out to confirm whether the operation is successful.

Summary:
Through the above steps, we successfully used Python to connect to the cloud interface to implement the video encryption function. At the same time, we also learned about some basic concepts and operating procedures of Youpaiyun. I hope this article can be helpful to you, and I wish you success in your development process!
