我们如何使用python flask从另一个路由中调用带有参数的路由？

Question

我正在发布一种形式，其中有两个输入到python flask路由。

  <form action = "http://localhost:5000/xyz" method = "POST">
     <p>x <input type = "text" name = "x" /></p>
     <p>y <input type = "text" name = "y" /></p>
     <p><input type = "submit" value = "submit" /></p>
  </form>

python flask代码就像。

@app.route('/xyz', methods = ['POST', 'GET'])
def xyz():
    if request.method == 'POST':
       x = request.form["x"]
       y = request.form["y"]
       callonemethod(x,y)
    return render_template('index.html', var1=var1, var2=var2)
       #abc(x,y) #can i call abc() like this .i want to call abc() immediately, as it is streaming log of callonemethod(x,y) in console.

@app.route('/abc', methods = ['POST', 'GET'])       
def abc():
    callanothermethod(x,y)
    return render_template('index.html', var1=var3, var2=var4)
    #I want to use that x, y here. also want to call abc() whenever i call xyz()

如何使用python flask从另一个路由调用带有参数的路由？

Answer 1

您有两个选择：
选择1：使用从路由中获得的参数进行重定向：

import os
from flask import Flask, redirect, url_for

@app.route('/abc/<x>/<y>')
def abc(x, y):
  callanothermethod(x,y)

然后您可以将调用的网址重定向到上面的他的路由，如下所示：

@app.route('/xyz', methods = ['POST', 'GET'])
def xyz():
    if request.method == 'POST':
       x = request.form["x"]
       y = request.form["y"]
       callonemethod(x,y)
       return redirect(url_for('abc', x=x, y=y))

另请参阅有关Flask中的重定向的文档

选项2：
似乎从多个不同位置调用了abc方法。这可能意味着将其从视图中解封装可能是一个好主意：

utils.py
from other_module import callanothermethod
def abc(x, y):
  callanothermethod(x,y)

import os
from flask import Flask, redirect, url_for
from utils import abc

@app.route('/abc/<x>/<y>')
def abc_route(x, y):
  callanothermethod(x,y)
  abc(x, y)

@app.route('/xyz', methods = ['POST', 'GET'])
def xyz():
    if request.method == 'POST':
       x = request.form["x"]
       y = request.form["y"]
       callonemethod(x,y)
       abc(x, y)
