融合门户




需求分析
我们希望用户可以通过门户提交请求,并且根据不同的服务类型收取费用。这些服务可能包括打印文件、申请签证等。
技术方案
我们将采用Python Flask框架作为后端,HTML+JavaScript作为前端。所有的业务逻辑将集中在核心模块中。
class ServiceRequest:
def __init__(self, service_type):
self.service_type = service_type
self.status = "pending"
def process(self):
if self.status == "pending":
print(f"Processing {self.service_type} request...")
self.status = "processed"
def charge(self, amount):
if self.status == "processed":
print(f"Charging ${amount} for {self.service_type} service.")
self.status = "charged"
from flask import Flask, request
app = Flask(__name__)
@app.route('/submit', methods=['POST'])
def submit_request():
data = request.get_json()
service_type = data['service_type']
amount = data['amount']
# 创建请求实例
req = ServiceRequest(service_type)
req.process()
req.charge(amount)
return {"status": "success", "message": f"{service_type} processed and charged."}
Submit Your Request
document.getElementById('requestForm').addEventListener('submit', function(event){
event.preventDefault();
const serviceType = document.getElementById('serviceType').value;
const amount = document.getElementById('amount').value;
fetch('/submit', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify({service_type: serviceType, amount: amount})
})
.then(response => response.json())
.then(data => {
document.getElementById('response').innerText = data.message;
});
});
总结
通过统一流程的设计,我们成功实现了服务大厅门户的计费功能。未来还可以扩展更多服务类型和支持多币种支付等功能。
