Nginx配置移动端访问自动重定向到指定请求

from flask import Flask, request, jsonify

app = Flask(__name__)


@app.route('/web/<int:num>/', methods=['GET'])
def web(num):
    # 获取当前访问的完整地址
    current_url = request.url

    # 构建响应数据
    response_data = {
        "current_url": current_url,
        "args": request.args.to_dict()
    }

    # 返回响应数据作为 JSON 响应
    return jsonify(response_data)


@app.route('/mobile/<int:num>/', methods=['GET'])
def mobile(num):
    # 获取当前访问的完整地址
    current_url = request.url

    # 构建响应数据
    response_data = {
        "current_url": current_url,
        "args": request.args.to_dict()
    }

    # 返回响应数据作为 JSON 响应
    return jsonify(response_data)
