Flask

Question

我希望能够在 return HTTP 调用的响应之前访问请求对象。我想通过 "teardown_request" 和 "after_request":

访问请求

from flask import Flask
...
app = Flask(__name__, instance_relative_config=True)
...

@app.before_request
def before_request():
    # do something

@app.after_request
def after_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(request)

@app.teardown_request
def teardown_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(request)

我看到我可以将请求添加到 g 并执行如下操作：

g.curr_request = request

@app.after_request
def after_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(g.curr_request)

不过上面的好像有点奇怪。我确信有更好的方法来访问请求。

谢谢

Answer 1

解决方法很简单 -

from flask import request

@app.after_request
def after_request(response):
    do_something_based_on_the_request_endpoint(request)
    return response

Answer 2

也尝试 teardown_request（例外）。这将执行 "regardless of whether there was an exception or not"。查看文档：http://flask.pocoo.org/docs/0.12/api/#flask.Flask.teardown_request

Flask - 在 after_request 或 teardown_request 中访问请求

Flask - access the request in after_request or teardown_request
