阿里云函数计算
我正在使用阿里云的函数计算（Function Compute）来生成看似正常的流量，这有助于掩盖我的代理服务器在GFW（中国国家防火墙）下的活动。我在代理服务器旁边部署了一个带宽服务器，而这个函数计算函数每分钟都会向带宽API发起请求。这样就形成了正常流量和代理流量的混合。

# 调用外部API的函数
def call_bandwidth_api():
try:
response = requests.get('https://www.lzwjava.xyz/bandwidth')
response.raise_for_status() # 抛出HTTP错误异常
return True # 表示成功
except Exception as e:
print("获取带宽数据时出错:", e)
return False # 表示失败

futures = [executor.submit(call_bandwidth_api) for _ in range(total_calls)]
# 等待所有任务完成并统计成功次数
