from flask import request

@app.route('/data')
def data():
    # here we want to get the value of user (i.e. ?user=some-value)
    user = request.args.get('user')

这个准则对我很有效:

from flask import Flask, request
app = Flask(__name__)
@app.route('/')
def search():
   query = request.args
   for key,value in query.items():
      print(key,value)
    return "Hello World"

if __name__ == '__main__':
  app.run(debug=True)

我们可以通过使用request.query_string来做到这一点。

例子:

让我们考虑view.py

from my_script import get_url_params

@app.route('/web_url/', methods=('get', 'post'))
def get_url_params_index():
    return Response(get_url_params())

您还可以使用Flask Blueprints - https://flask.palletsprojects.com/en/1.1.x/blueprints/使其更加模块化

让我们考虑将名字作为查询字符串的一部分传递 / web_url / ?first_name =约翰

## here is my_script.py

## import required flask packages
from flask import request
def get_url_params():
    ## you might further need to format the URL params through escape.    
    firstName = request.args.get('first_name') 
    return firstName
    

正如你所看到的，这只是一个小例子-你可以获取多个值+格式化这些并使用它或将其传递到模板文件。

对查询字符串尝试这样做:

from flask import Flask, request

app = Flask(__name__)

@app.route('/parameters', methods=['GET'])
def query_strings():

    args1 = request.args['args1']
    args2 = request.args['args2']
    args3 = request.args['args3']

    return '''<h1>The Query String are...{}:{}:{}</h1>''' .format(args1,args2,args3)


if __name__ == '__main__':

    app.run(debug=True)

输出:

如果请求是GET，我们传递一些查询参数，

fro`enter code here`m flask import request
@app.route('/')
@app.route('/data')
def data():
   if request.method == 'GET':
      # Get the parameters by key
      arg1 = request.args.get('arg1')
      arg2 = request.args.get('arg2')
      # Generate the query string
      query_string="?arg1={0}&arg2={1}".format(arg1, arg2)
      return render_template("data.html", query_string=query_string)

Werkzeug/Flask已经为您解析了所有内容。不需要再用urlparse做同样的工作:

from flask import request

@app.route('/')
@app.route('/data')
def data():
    query_string = request.query_string  ## There is it
    return render_template("data.html")
