Question

我正在测试嵌入Braintree平台的Google App Engine中的应用。我正在使用他们的代码进行此测试来处理虚构的事务。在我的html中，我有一个表单，在提交时将其信息路由到＆＃34; / create_transaction＆＃34;下面。服务器代码是：

@app.route("/create_transaction", methods=["POST"])
def create_transaction():
    result = braintree.Transaction.sale({
        "amount": "1000.00",
        "credit_card": {
            "number": request.form["number"],
            "cvv": request.form["cvv"],
            "expiration_month": request.form["month"],
            "expiration_year": request.form["year"]
        },
        "options": {
            "submit_for_settlement": True
        }
    })
    if result.is_success:
        return "<h1>Success! Transaction ID: {0}</h1>".format(result.transaction.id)
    else:
        return "<h1>Error: {0}</h1>".format(result.message)

浏览器不会返回结果，而是呈现内部服务器错误500. Traceback如下：

为什么GAE会抛出此异常？

Answer 1

_{我在Braintree工作。如果您需要更多帮助，可以随时get in touch with our support team。}

这似乎是problem with certain versions of urllib3 / requests (a Braintree dependency) on GAE。

尝试将其添加到app.yaml文件中：

libraries:
- name: ssl
  version: latest

并确保您已为该应用程序启用了结算功能。

如果这不能解决问题，您可以查看上面链接的github问题以获取更多信息。

AttributeError：'NoneType'对象在使用Braintree的GAE中没有属性'wrap_socket'
