用于创建可点击链接的Python代码抛出错误

name = "John"
url = "http://example.com/user?id=" + name  # 如果name包含特殊字符，可能会导致错误

from urllib.parse import quote

name = "John Doe"
encoded_name = quote(name)
url = f"http://example.com/user?id={encoded_name}"

name = "John Doe"
url = f"http://example.com/user?id={quote(name)}"

from flask import url_for

@app.route('/user/<username>')
def user_profile(username):
    return f'User {username}'

# 在模板中
<a href="{{ url_for('user_profile', username=name) }}">Profile</a>

from urllib.parse import quote

def create_clickable_link(base_url, params):
    query_string = '&'.join(f'{k}={quote(v)}' for k, v in params.items())
    full_url = f"{base_url}?{query_string}"
    return full_url

# 使用示例
params = {'id': 'John Doe', 'action': 'view'}
link = create_clickable_link("http://example.com/user", params)
print(link)  # 输出: http://example.com/user?id=John%20Doe&action=view
