python - 如何让Braintree的python客户端重用连接？

Question

Braintree 提供 Python library用于与他们的 API 交互。

但是，启用日志记录后，可以看到每个 API 调用都会协商新的 SSL 连接。

braintree.Customer.create({'first_name': 'Alice'})
braintree.Customer.create({'first_name': 'Bob'})

INFO:requests.packages.urllib3.connectionpool:Starting new HTTPS connection (1): api.sandbox.braintreegateway.com 
DEBUG:requests.packages.urllib3.connectionpool:"POST /merchants/hx4tr43ms83q8x9g/customers HTTP/1.1" 201 None
INFO:requests.packages.urllib3.connectionpool:Starting new HTTPS connection (1): api.sandbox.braintreegateway.com 
DEBUG:requests.packages.urllib3.connectionpool:"POST /merchants/hx4tr43ms83q8x9g/customers HTTP/1.1" 201 None     

如果有大量的调用，这会导致大量的资源浪费，尤其是时间。

是否有任何方法可以将 Braintree 配置为重用/池连接，底层请求模块应该支持这些连接？

它不受官方支持，因为它覆盖了私有(private)方法，但您可以提供替代的 HTTP 实现。这将通过 session 发送所有 API 请求。

class SessionHttp(braintree.util.http.Http):
    session = requests.Session()

    def __init__(self, config, environment=None):
        super(SessionHttp, self).__init__(config, environment)

    def _Http__request_function(self, method):
        if method == "GET":
            return SessionHttp.session.get
        elif method == "POST":
            return SessionHttp.session.post
        elif method == "PUT":
            return SessionHttp.session.put
        elif method == "DELETE":
            return SessionHttp.session.delete

braintree.Configuration.configure(
    # ...
    http_strategy=SessionHttp
)

braintree.Customer.create({'first_name': 'Alice'})
braintree.Customer.create({'first_name': 'Bob'})

INFO:requests.packages.urllib3.connectionpool:Starting new HTTPS connection (1): api.sandbox.braintreegateway.com 
DEBUG:requests.packages.urllib3.connectionpool:"POST /merchants/hx4tr43ms83q8x9g/customers HTTP/1.1" 201 None
