python - Falcon 过早关闭连接

Question

Falcon 框架永远不会返回整个响应。我从 curl (或任何其他 HTTP 工具)得到的只是:

$ curl -q -D - -o - "localhost:8000/post_account?email=someone@example.com

HTTP/1.1 200 OK
Server: gunicorn/19.4.5
Date: Thu, 31 Mar 2016 11:36:49 GMT
Connection: close
content-length: 3
content-type: application/json; charset=utf-8

curl: (18) transfer closed with 3 bytes remaining to read

index.py

这是定义路由的引导脚本。

import falcon
from routes import route_account


app = falcon.API()
post_account = route_account.RoutePostAccount()

# Routes
app.add_route('/post_account', post_account)

route_account.py

这是路由处理程序类。我检查了一下，从 _result = account.create_account(**_payload) 收到的结果很好。

from falcon.util import uri
from objects.account_base import AccountBase

account = AccountBase()


class RoutePostAccount(object):

    @staticmethod
    def on_get(req, resp):

        # Convert query parameters string to dict
        _payload = uri.parse_query_string(req.query_string)
        # Create account
        _result = account.create_account(**_payload)
        # Send response
        resp.status = _result.get('status', {}).get('code')
        resp.body = _result

网络服务器

$ gunicorn index:app

有人能看到我看不到的东西吗？感谢您的帮助。

使用gunicorn index:app --log-level DEBUG来启动你的gunicorn worker 。然后，再次尝试curl命令并查看gunicorn控制台:肯定有错误。我认为 account.create_account(**_payload) 返回的内容无效。示例:如果您在 python 3 上运行它，那么它必须返回一个字典，但 falcon 需要一个字节字符串，因此它会失败并关闭连接。您必须将 account.create_account(**_payload) 的输出序列化(到 json、xml，无论您喜欢什么)。这样:

route_account.py:

import json

from falcon.util import uri
from objects.account_base import AccountBase

account = AccountBase()


class RoutePostAccount(object):

    @staticmethod
    def on_get(req, resp):

        # Convert query parameters string to dict
        _payload = uri.parse_query_string(req.query_string)
        # Create account
        _result = account.create_account(**_payload)
        # Send response
        resp.status = _result.get('status', {}).get('code')
        resp.body = json.dumps(_result)
