How do you access query parameters or the query string in Flask routes? It's not obvious from the Flask documentation.
下面的示例路由/data
说明了我要访问该数据的上下文.如果有人请求类似 example.com/data?abc=123
之类的内容,我希望访问字符串?abc = 123
或能够检索参数值像 abc
.

below illustrates the context that I would like to access that data. If someone requests something like example.com/data?abc=123

or to be able to retrieve the value of parameters like abc
.
@app.route("/data")
def data():
# query_string = ???
return render_template("data.html")
推荐答案
from flask import request
@app.route('/data')
def data():
# here we want to get the value of user (i.e. ?user=some-value)
