Question

我有一个Android客户端和一个应该相互通信的服务器。我正在使用烧瓶并在app引擎上托管我的服务器。这是main.py文件：

from flask import Flask
import braintree

braintree.Configuration.configure(braintree.Environment.Sandbox,
                                  merchant_id="something_censored",
                                  public_key="something_censored",
                                  private_key="something_censored")

app = Flask(__name__)

if __name__ == '__main__':
    app.run()

@app.route('/')
def hello_world():
    return 'Hello World!'

@app.route('/<name>')
def hello_name(name):
    return "Howdy {}".format(name)


@app.route('/client_token', methods=["GET"])
def client_token():
    return braintree.ClientToken.generate()

@app.route('/create_customer/<firstName>/<lastName>/<email>', methods=["GET"])
def create_customer(firstName, lastName, email):
    result = braintree.Customer.create({
        "first_name": firstName,
        "last_name": lastName,
        "email": email,
    })
    return result.customer.id


@app.route('/create_payment_method_for_customer/<customerId>/<clientNonce>', methods=["POST"])
def create_payment_method_for_customer(customerId, clientNonce):
    braintree.PaymentMethod.create({
        "customer_id": customerId,
        "payment_method_nonce": clientNonce,
        "options": {
            "verify_card": True,
            "verification_merchant_account_id": "ydt4s72wzw46wdbs",
            "verification_amount": "0.00",
        }
    })

@app.route('/get_customer_payment_methods/<customer_id>')
def get_customer_payment_methods(customer_id):
    result = braintree.Customer.find(customer_id)
    return result.payment_methods

我已经使用pip install braintree命令在python中下载了braintree服务器sdk，我已经安装了2.7 python应用程序引擎sdk。在http://birthpayserver.appspot.com/部署了在app引擎上托管的烧瓶服务器后，我调用了'/ client_token'路由，如下所示：

Uri.Builder builder = new Uri.Builder()
            .scheme("http")
            .authority("www.birthpayserver.appspot.com")
            .appendPath("create_customer")
            .appendPath(firstName)
            .appendPath(lastName)
            .appendPath(email);
    String url = builder.build().toString();

    AsyncHttpClient client = new AsyncHttpClient();
    client.get(url, new TextHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, String customerId) {
            mCustomerId = customerId;
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
            Toast.makeText(getBaseContext(), "Failed to create account, try again.", Toast.LENGTH_LONG).show();
            Log.d(LOG_TAG, responseString);
        }
    });

调用onFailure方法，responseString等于：{/ p>

<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>500 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered an error and could not complete your request.
<p>Please try again in 30 seconds.</h2>
<h2></h2>
</body></html>

当我运行我的服务器时，日志如下：

编辑：

再次运行我的烧瓶服务器时，日志显示有ImportError: No module named braintree，但我安装了braintree。

如何让服务器在app引擎上运行，以便它接受并响应http个请求？

为什么我的客户端无法连接到我的服务器？
