MobileAgent API集成架构解析
MobileAgent采用分层架构设计，使第三方API集成变得简单高效。以下是核心架构图：
核心组件职责
| 组件 | 职责 | 关键文件 |
|---|---|---|
| Manager Agent | 任务规划与资源调度 | MobileAgentE/agents.py |
| Controller | 设备控制与API调用协调 | MobileAgent/controller.py |
| API适配层 | 第三方服务统一接口封装 | MobileAgent/api.py |
| 密钥管理 | 安全存储与获取API凭证 | inference_agent_E.py, config.json |
环境变量与配置管理
MobileAgent采用环境变量优先的配置策略，确保敏感信息安全：
# Mobile-Agent-E/inference_agent_E.py 中的API密钥管理示例
OPENAI_API_KEY = os.environ.get("OPENAI_API_KEY", default=None)
GEMINI_API_KEY = os.environ.get("GEMINI_API_KEY", default=None)
CLAUDE_API_KEY = os.environ.get("CLAUDE_API_KEY", default=None)
QWEN_API_KEY = os.environ.get("QWEN_API_KEY", default=None)
配置文件示例（PC-Agent/config.json）：
{
"api_keys": {
"alipay": {
"app_id": "your_app_id",
"private_key": "path/to/private/key.pem"
},
"amap": {
"key": "your_amap_api_key"
}
},
"timeout": 30,
"retry_count": 3
}
支付服务集成实战
支付宝API集成
集成步骤
-
准备工作
- 在支付宝开放平台注册应用并获取APP_ID
- 生成RSA密钥对并配置到开放平台
- 安装支付宝SDK:
pip install alipay-sdk-python
-
创建支付API适配类
# 在MobileAgent/api.py中添加
import alipay
from alipay.utils import AliPayConfig
class AlipayAdapter:
def __init__(self, app_id, private_key_path, public_key_path):
self.config = AliPayConfig(
appid=app_id,
app_notify_url=None, # 可选, 不填则使用默认回调地址
app_private_key_string=open(private_key_path).read(),
alipay_public_key_string=open(public_key_path).read(),
sign_type="RSA2", # RSA 或者 RSA2
debug=False # 默认False
)
self.client = alipay.AlipayClient(config=self.config)
def create_order(self, out_trade_no, total_amount, subject):
"""创建支付订单"""
order_string = self.client.api_alipay_trade_page_pay(
out_trade_no=out_trade_no,
total_amount=total_amount,
subject=subject,
return_url="https://example.com/return",
notify_url="https://example.com/notify"
)
return f"{self.client.gateway}?{order_string}"
def verify_payment(self, data, signature):
"""验证支付通知"""
return self.client.verify(data, signature)
- 集成到MobileAgent工作流
# 在MobileAgent/controller.py中添加支付流程控制
def process_payment(self, payment_info):
# 1. 获取支付配置
payment_config = self.load_payment_config(payment_info['type'])
# 2. 创建支付适配器实例
if payment_info['type'] == 'alipay':
adapter = AlipayAdapter(
app_id=payment_config['app_id'],
private_key_path=payment_config['private_key_path'],
public_key_path=payment_config['public_key_path']
)
# 3. 创建订单
order_url = adapter.create_order(
out_trade_no=f"ORDER_{int(time.time())}",
total_amount=payment_info['amount'],
subject=payment_info['subject']
)
# 4. 在移动设备上打开支付链接
self.open_url(order_url)
# 5. 等待并验证支付结果
payment_result = self.wait_for_payment_result(payment_info['timeout'])
return payment_result
错误处理与重试机制
# 支付重试逻辑实现
def safe_payment_call(self, payment_func, max_retries=3, backoff_factor=0.3):
retry_count = 0
while retry_count < max_retries:
try:
return payment_func()
except ConnectionError as e:
self.logger.error(f"支付连接错误: {str(e)}")
except TimeoutError as e:
self.logger.error(f"支付超时: {str(e)}")
except Exception as e:
self.logger.error(f"支付处理错误: {str(e)}")
# 非网络错误不再重试
if not isinstance(e, (ConnectionError, TimeoutError)):
break
retry_count += 1
sleep_time = backoff_factor * (2 ** (retry_count - 1))
time.sleep(sleep_time)
# 达到最大重试次数后记录失败并上报
self.record_failed_payment(payment_info)
raise PaymentException(f"支付失败，已重试{max_retries}次")
微信支付集成要点
微信支付集成与支付宝类似，但有以下关键差异需要注意：
- 签名算法不同：微信支付使用HMAC-SHA256而非RSA
- 证书要求：微信支付API V3需要TLS证书验证
- 接口风格：RESTful风格API，返回JSON格式数据
微信支付适配器核心实现：
class WechatPayAdapter:
def __init__(self, mch_id, api_key, cert_path, key_path):
self.mch_id = mch_id
self.api_key = api_key
self.cert_path = cert_path
self.key_path = key_path
self.base_url = "https://api.mch.weixin.qq.com/v3/pay/transactions"
def create_order(self, order_info):
"""创建微信支付订单"""
nonce_str = self._generate_nonce_str()
timestamp = int(time.time())
# 构建请求参数
params = {
"appid": order_info['appid'],
"mchid": self.mch_id,
"out_trade_no": order_info['out_trade_no'],
"description": order_info['subject'],
"amount": {"total": int(order_info['amount'] * 100), "currency": "CNY"},
"notify_url": order_info['notify_url'],
"client_ip": "127.0.0.1",
"nonce_str": nonce_str
}
# 生成签名
signature = self._generate_signature(params, timestamp, nonce_str)
# 发送请求
headers = {
"Content-Type": "application/json",
"Authorization": f'WECHATPAY2-SHA256-RSA2048 {signature}',
"Wechatpay-Timestamp": str(timestamp),
"Wechatpay-Nonce": nonce_str,
"Wechatpay-Serial": self._get_certificate_serial()
}
response = requests.post(
f"{self.base_url}/jsapi",
json=params,
headers=headers,
cert=(self.cert_path, self.key_path)
)
return response.json()
支付安全最佳实践
-
敏感信息保护
- 所有API密钥必须通过环境变量或加密配置文件管理
- 支付金额等关键参数必须服务端验证，防止客户端篡改
- 实现示例：Mobile-Agent-E/inference_agent_E.py中的环境变量管理方式
-
支付流程安全
- 使用HTTPS加密所有支付相关通信
- 实现幂等性设计，防止重复支付
- 严格验证支付通知的签名
-
日志与审计
def log_payment_event(self, event_type, payment_info, details=None): log_entry = { "timestamp": time.time(), "event_type": event_type, "payment_id": payment_info.get("out_trade_no"), "amount": payment_info.get("amount"), "status": payment_info.get("status"), "device_id": self.device_info.get("device_id"), "details": details or {} } # 确保不记录敏感信息 if "password" in log_entry["details"]: log_entry["details"]["password"] = "***" if "api_key" in log_entry["details"]: log_entry["details"]["api_key"] = "***" self.logger.info(json.dumps(log_entry)) # 保存到审计日志文件 with open("payment_audit.log", "a") as f: f.write(json.dumps(log_entry) + "\n")
地图服务集成详解
高德地图API集成
核心功能实现
- 地理编码与逆地理编码
# MobileAgent/api.py 中的地图服务集成
class AMapAdapter:
def __init__(self, api_key):
self.api_key = api_key
self.base_url = "https://restapi.amap.com/v3"
def geocode(self, address):
"""将地址转换为经纬度坐标"""
params = {
"key": self.api_key,
"address": address,
"output": "json"
}
response = requests.get(f"{self.base_url}/geocode/geo", params=params)
result = response.json()
if result["status"] == "1" and int(result["count"]) > 0:
location = result["geocodes"][0]["location"]
return tuple(map(float, location.split(',')))
return None
def reverse_geocode(self, longitude, latitude):
"""将经纬度转换为地址"""
params = {
"key": self.api_key,
"location": f"{longitude},{latitude}",
"output": "json"
}
response = requests.get(f"{self.base_url}/geocode/regeo", params=params)
result = response.json()
if result["status"] == "1":
return result["regeocode"]["formatted_address"]
return None
- 路径规划与导航
def get_route(self, origin, destination, route_type="driving"):
"""获取两点之间的路线规划"""
params = {
"key": self.api_key,
"origin": f"{origin[0]},{origin[1]}",
"destination": f"{destination[0]},{destination[1]}",
"strategy": "0", # 0-最快路线
"output": "json"
}
response = requests.get(f"{self.base_url}/{route_type}/path", params=params)
result = response.json()
if result["status"] == "1":
# 提取关键路线信息
route = {
"distance": result["route"]["paths"][0]["distance"],
"duration": result["route"]["paths"][0]["duration"],
"steps": []
}
# 解析步骤信息
for step in result["route"]["paths"][0]["steps"]:
route["steps"].append({
"instruction": step["instruction"],
"distance": step["distance"],
"duration": step["duration"],
"polyline": step["polyline"]
})
return route
return None
地图数据缓存策略
为提高性能并减少API调用次数，实现多级缓存机制：
class MapCacheManager:
def __init__(self, cache_dir="map_cache", ttl_map={
"geocode": 86400 * 7, # 地址编码缓存7天
"route": 3600, # 路线缓存1小时
"poi": 86400 # POI缓存1天
}):
self.cache_dir = cache_dir
self.ttl_map = ttl_map
os.makedirs(cache_dir, exist_ok=True)
def _get_cache_key(self, func_name, params):
"""生成唯一缓存键"""
param_str = "_".join([f"{k}_{v}" for k, v in sorted(params.items())])
return hashlib.md5(f"{func_name}_{param_str}".encode()).hexdigest()
def get_cached_data(self, func_name, params):
"""获取缓存数据"""
cache_key = self._get_cache_key(func_name, params)
cache_path = os.path.join(self.cache_dir, cache_key)
if os.path.exists(cache_path):
# 检查缓存是否过期
cache_time = os.path.getmtime(cache_path)
current_time = time.time()
if current_time - cache_time < self.ttl_map.get(func_name, 3600):
with open(cache_path, "r") as f:
return json.load(f)
return None
def cache_data(self, func_name, params, data):
"""缓存API响应数据"""
cache_key = self._get_cache_key(func_name, params)
cache_path = os.path.join(self.cache_dir, cache_key)
with open(cache_path, "w") as f:
json.dump(data, f)
return True
百度地图API集成差异
百度地图API与高德地图在接口设计和响应格式上有差异，需要针对性适配：
class BaiduMapAdapter(MapAdapterBase):
def __init__(self, api_key):
super().__init__(api_key)
self.base_url = "http://api.map.baidu.com"
def geocode(self, address, city=None):
"""百度地图地理编码实现"""
params = {
"ak": self.api_key,
"address": address,
"output": "json"
}
if city:
params["city"] = city
response = requests.get(f"{self.base_url}/geocoding/v3", params=params)
result = response.json()
if result["status"] == 0:
location = result["result"]["location"]
return (location["lng"], location["lat"])
return None
# 其他方法实现...
常见集成问题与解决方案
连接超时与重试策略
基于MobileAgent现有代码实现增强的重试机制：
# 改进自 Mobile-Agent-E/inference_agent_E.py 的API调用方法
def robust_api_call(self, api_func, max_retries=3, backoff_factor=0.5):
"""带指数退避的API调用重试机制"""
retry_count = 0
while retry_count < max_retries:
try:
# 记录API调用开始时间
start_time = time.time()
# 执行API调用
response = api_func()
# 记录API调用耗时
self.log_api_metrics(
api_name=api_func.__name__,
status="success",
duration=time.time() - start_time
)
return response
except requests.exceptions.RequestException as e:
# 计算重试延迟
delay = backoff_factor * (2 ** retry_count)
# 记录失败信息
self.log_api_metrics(
api_name=api_func.__name__,
status="failure",
duration=time.time() - start_time,
error=str(e)
)
# 日志记录与重试提示
self.logger.warning(
f"API调用失败 (尝试 {retry_count+1}/{max_retries}): {str(e)}. "
f"将在 {delay:.2f} 秒后重试..."
)
# 等待重试
time.sleep(delay)
retry_count += 1
# 达到最大重试次数
self.logger.error(f"API调用失败，已达到最大重试次数 ({max_retries})")
raise APIException(f"API调用持续失败: {str(e)}")
支付状态同步问题
def sync_payment_status(self, order_id, max_attempts=10, interval=3):
"""支付状态同步轮询机制"""
attempt = 0
while attempt < max_attempts:
try:
# 查询支付状态
status = self.payment_adapter.query_order_status(order_id)
# 检查状态
if status == "SUCCESS":
return {"status": "success", "order_id": order_id}
elif status in ["PENDING", "PROCESSING"]:
# 支付处理中，继续轮询
attempt += 1
time.sleep(interval)
else:
# 支付失败
return {"status": "failed", "order_id": order_id, "reason": status}
except Exception as e:
self.logger.error(f"查询支付状态失败: {str(e)}")
attempt += 1
time.sleep(interval)
# 轮询超时，返回未知状态
return {"status": "unknown", "order_id": order_id}
地图服务配额管理
class MapAPIQuotaManager:
def __init__(self, quota_config_path="map_api_quota.json"):
self.quota_config = self._load_config(quota_config_path)
self.usage_tracker = self._load_usage_data()
self.lock = threading.Lock()
def check_quota(self, api_type):
"""检查API调用配额是否充足"""
with self.lock:
today = datetime.date.today().isoformat()
if today not in self.usage_tracker:
self.usage_tracker[today] = {}
if api_type not in self.usage_tracker[today]:
self.usage_tracker[today][api_type] = 0
# 检查是否超过配额
daily_quota = self.quota_config.get(api_type, {}).get("daily_quota", 1000)
if self.usage_tracker[today][api_type] >= daily_quota:
return False
return True
def record_usage(self, api_type):
"""记录API调用"""
with self.lock:
today = datetime.date.today().isoformat()
self.usage_tracker[today][api_type] = self.usage_tracker[today].get(api_type, 0) + 1
self._save_usage_data()
def get_remaining_quota(self, api_type):
"""获取剩余配额"""
today = datetime.date.today().isoformat()
used = self.usage_tracker.get(today, {}).get(api_type, 0)
total = self.quota_config.get(api_type, {}).get("daily_quota", 1000)
return max(0, total - used)
