Falcon过早关闭连接

Question

Falcon框架从不返回整个响应。我从curl（或任何其他HTTP工具）得到的都是：

$ curl -q -D - -o - "localhost:8000/post_account?email=[e-mail]
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)收到的结果是好的。

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

Web服务器

$ gunicorn index:app

有人看到我没看到的东西吗？谢谢你的帮助。

使用gunicorn index:app --log-level DEBUG启动gunicorn工人。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)正在返回无效的内容。示例：如果你在python 3上运行它，那么它肯定会返回一个字典，但falcon需要一个字节字符串，所以它失败并关闭连接。您必须序列化（到json、xml，无论您喜欢什么）account.create_account(**_payload)的输出。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)
