Question

我想在返回HTTP调用的响应之前能够访问请求对象。我希望通过＆＃34; teardown_request＆＃34;访问请求。和＆＃34; after_request＆＃34;：

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并执行以下操作：

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)

但上面看起来有点奇怪。我确信有更好的方式来访问请求。

Answer 1

解决方案很简单 -

from flask import request

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

Answer 2

同时尝试teardown_request（例外）。这将执行＆＃34;无论是否存在异常＆＃34;。查看文档：{{3}}

Flask - 在after_request或teardown_request中访问请求
