想要在Flask去使用Http的错误码，
不想要直接写400，表示bad request
而想要试用别处已经定义好的http的状态码
搜：
Flask Bad Request
Application Errors — Flask Documentation (0.11)
-》
HTTP Exceptions — Werkzeug Documentation (0.11)
“
exception werkzeug.exceptions.HTTPException(description=None, response=None)
Baseclass for all HTTP exceptions. This exception can be called as WSGI application to render a default error page or you can catch the subclasses of it independently and render nicer error messages.
call(environ, start_response)
Call the exception as WSGI application.
Parameters:
environ – the WSGI environment.
start_response – the response callable provided by the WSGI server.
get_response(environ=None)
Get a response object. If one was passed to the exception it’s returned directly.
Parameters: environ – the optional environ for the request. This can be used to modify the response depending on how the request looked like.
Returns: a Response object or a subclass thereof.

HTTP Exceptions — Werkzeug Documentation (0.11)
“
exception werkzeug.exceptions.BadRequest(description=None, response=None)
400 Bad Request
Raise if the browser sends something to the application the application or server cannot handle.

还是没找到，具体如何使用。
Flask http status code
Custom Error Pages — Flask Documentation (0.11)
Implementing API Exceptions — Flask Documentation (0.11)
Flask http status code definition
List of HTTP status codes – Wikipedia
python – Flask – How to create custom abort() code? – Stack Overflow
python – Setting HTTP status code in Bottle? – Stack Overflow
去试试：
############################################################ # Flask ############################################################ from werkzeug.exceptions import * def put(self, userId, taskId): gLog.debug("BadRequest=%s", BadRequest) gLog.debug("BadRequest.code=%s", BadRequest.code) if userId == "": return genRespFailDict(code=BadRequest.code, message="user id can not empty") |
好像是可以的：
| <div–<—————————————————————————— DEBUG in Task [/root/RunningFast/staging/runningfast/resources/Task.py:209]: BadRequest=<class ‘werkzeug.exceptions.BadRequest’> <div–<—————————————————————————— <div–<—————————————————————————— DEBUG in Task [/root/RunningFast/staging/runningfast/resources/Task.py:210]: BadRequest.code=400 |
【总结】
暂时可以去用：
from werkzeug.exceptions import * gLog.debug("BadRequest.code=%s", BadRequest.code) |
而使得不用直接写对应的400的值，显得更加直观。
对于其它异常的写法，详见：
HTTP Exceptions — Werkzeug Documentation (0.11)
