我正在做一个ajax POST请求,我得到了这个例外:
[Fri Nov 29 20:48:55 2013] [error] [client 192.168.25.100] self.raise_routing_exception(req)
[Fri Nov 29 20:48:55 2013] [error] [client 192.168.25.100] File "/usr/lib/python2.6/site-packages/flask/app.py", line 1439, in raise_routing_exception
[Fri Nov 29 20:48:55 2013] [error] [client 192.168.25.100] raise FormDataRoutingRedirect(request)
[Fri Nov 29 20:48:55 2013] [error] [client 192.168.25.100] FormDataRoutingRedirect: A request was sent to this URL (http://example.com/myurl) but a redirect was issued automatically by the routing system to "http://example.com/myurl/". The URL was defined with a trailing slash so Flask will automatically redirect to the URL with the trailing slash if it was accessed without one. Make sure to directly send your POST-request to this URL since we can't make browsers or HTTP clients redirect with form data reliably or without user interaction.
路线定义是:
@app.route('/myurl')
def my_func():
我可以在Firebug中看到请求是在没有尾部斜杠的情况下发送的:
http://example.com/myurl
Content-Type application/x-www-form-urlencoded; charset=UTF-8
我在另一个模块中有这个:
@app.route('/')
@app.route('/<a>/')
@app.route('/<a>/<b>')
def index(a='', b=''):
这最后一个会妨碍吗?或者是什么? Flask版本为0.10.1
答案 0 :(得分:7)
我的猜测是,您的/myurl
路由未定义为接受POST
个请求,而您的/<a>/
路由是,因此Werkzeug选择了/<a>/
。
解释以斜杠结尾的路由的行为here。默认情况下,调用使用尾部斜杠定义的路径而不使用该斜杠会触发重定向到URL的尾部斜杠版本。这当然不适用于POST
次请求,因此您获得FormDataRoutingRedirect
例外。
我怀疑如果您将POST
请求发送到/myurl/
,那么您的/<a>/
路由会被调用得很好,但显然这不是您想要的。
我认为您遗失的是接受POST
/myurl
的请求,您可以执行以下操作:
@app.route('/myurl', methods = ['GET', 'POST'])
def my_func():
