调用函数计算5和6的加减乘除

下面是调用函数计算5和6的加减乘除的示例代码：

import requests

def calculate(num1, num2, operator):
    url = f'https://xxxxx.cn-hangzhou.fc.aliyuncs.com/2016-08-15/proxy/xxxxx/func/'
    if operator == '+':
        payload = {'num1': num1, 'num2': num2, 'operator': operator}
        r = requests.get(url, params=payload)
        return r.text.strip()
    elif operator == '-':
        payload = {'num1': num1, 'num2': num2, 'operator': operator}
        r = requests.get(url, params=payload)
        return r.text.strip()
    elif operator == '*':
        payload = {'num1': num1, 'num2': num2, 'operator': operator}
        r = requests.get(url, params=payload)
        return r.text.strip()
    elif operator == '/':
        payload = {'num1': num1, 'num2': num2, 'operator': operator}
        r = requests.get(url, params=payload)
        return r.text.strip()
    else:
        return 'Invalid operator'

print(calculate(5, 6, '+')) # 11
print(calculate(5, 6, '-')) # -1
print(calculate(5, 6, '*')) # 30
print(calculate(5, 6, '/')) # 0.8333333333333334

其中，`url` 是函数计算的接口地址，`payload` 是请求的参数，`requests.get()` 方法发送 GET 请求并获取响应结果。需要将 `xxxxx` 替换为自己的函数计算服务名称，`func` 替换为自己的函数名称。
