How to implement test paper links and QR code sharing in online answering questions

In the modern education environment, more and more students and teachers choose to learn online and answer questions online. The online question answering platform provides students with a more convenient and flexible learning method. In such online answering, test paper links and QR code sharing are very important functions, allowing students and teachers to obtain and share test papers more conveniently.

The test paper link is a unique URL address that can be directly linked to the specified test paper page. Through the test paper link, students can directly enter the answering interface to answer questions, and teachers can share the link with students to facilitate students to participate in exams or assignments. Test paper links are usually generated through the API interface provided by the online question answering platform, and the specific generation method and parameters can be called according to the platform's documents and requirements.

The following is a sample code that generates test paper links by using the Python programming language and the requests library:

import requests

def generate_paper_link(paper_id):
    url = "https://api.examplatform.com/v1/paper"
    headers = {
        "Authorization": "Bearer YOUR_ACCESS_TOKEN"
    }
    params = {
        "paper_id": paper_id
    }
    response = requests.get(url, headers=headers, params=params)
    if response.status_code == 200:
        paper_link = response.json()["data"]["paper_link"]
        return paper_link
    else:
        return None

paper_id = "1234567890"  # 试卷的ID
paper_link = generate_paper_link(paper_id)
if paper_link:
    print("试卷链接：", paper_link)
else:
    print("试卷链接生成失败")

In the above code, you first need to replace YOUR_ACCESS_TOKEN and paper_id is the actual access token and paper ID. Then, obtain the test paper link by calling the test paper API interface and passing in the test paper ID. Finally, determine whether the test paper link is successfully generated based on the results returned by the interface.

In addition to test paper links, QR code sharing is also a common function in online answering questions. By scanning the QR code, students can directly enter the answer page, avoiding the trouble of manually entering links. The QR code can be generated using a third-party library and the test paper link can be embedded into the QR code.

The following is a sample code that uses the Python programming language and the qrcode library to generate a QR code image:

import qrcode

def generate_qrcode(paper_link):
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=10,
        border=4,
    )
    qr.add_data(paper_link)
    qr.make(fit=True)
    qr_img = qr.make_image(fill_color="black", back_color="white")
    qr_img.save("qrcode.png")

generate_qrcode(paper_link)

In the above code, you first need to replace paper_link with Actual question paper link. Then, the QR code image is generated by calling the function of the qrcode library, and the test paper link is embedded into the QR code. Finally, save the generated QR code image to the local file qrcode.png.

Through the above code example, we can share the test paper link and QR code in the online answer. Students can directly enter the answer interface through the test paper link, and teachers can share the link with students to facilitate their participation in exams or assignments. The QR code sharing is more convenient for students. By scanning the QR code, they can enter the answer page. The implementation of this function greatly improves the convenience and efficiency of learning.
