How to use Python to connect to Youpaiyun interface to implement video interception function
Youpaiyun is a high-performance cloud storage platform that provides a rich interface that can upload and transcode images and videos. , editing and other functions. This article will introduce how to use Python to connect to the Youpai Cloud interface and implement the video interception function.
1. Install dependent libraries
First, we need to install Python’s dependent libraries. Use the following command to install the required libraries:
pip install requests pip install datetime
2. Obtain Youpai Cloud API authorization
Before using Youpai Cloud interface, we need to obtain API authorization to obtain access to Youpai Cloud Permissions for cloud resources. Register an account on Youpaiyun's official website, create a service, and obtain the service's operator name (Operator) and password (Password).
3. Write code
The following is a sample code that uses Python to implement the video interception function:
import requests import datetime def get_signature(params, password): signature = "" for key in sorted(params.keys()): value = params[key] signature += key + str(value) signature += password return signature def cut_video(file_url, offset, duration): service = "your_service_name" operator = "your_operator_name" password = "your_password" bucket = "your_bucket_name" saveas = "/path/to/saveas.jpg" params = { "service": service, "bucket": bucket, "notify_url": "", "saveas": saveas, "expiration": int(datetime.datetime.now().timestamp()) + 3600, "offset": offset, "duration": duration, } signature = get_signature(params, password) headers = { "Authorization": "UPYUN " + operator + ":" + signature, } response = requests.post(file_url, headers=headers, data=params) return response if __name__ == "__main__": file_url = "your_file_url" offset = 5 duration = 10 response = cut_video(file_url, offset, duration) print(response.text)
In this code, we first define a file named# The function of ##get_signature is used to generate the signature required by the Youpai Cloud interface. Then the
cut_video function is defined, which accepts three parameters, namely the URL of the video, the starting time of the interception, and the duration of the interception. Inside the function, we need to fill in the Youpai cloud service, operator, password, space name, save path and other information into the corresponding variables in the code.
cut_video function, we first define a
params dictionary containing all request parameters. Then use the
get_signature function to generate a signature and add the signature to the request header. Finally, we use the
requests.post method to send a POST request, passing the video URL, interception start time, and interception duration as parameters to the Youpai Cloud interface. The interface will return the intercepted video image and print the result.
your_service_name,
your_operator_name,
your_password in the file The values of variables such as ,
your_bucket_name,
/path/to/saveas.jpg, and
your_file_url. Then run the code to intercept the video and save the intercepted picture.
