【问题标题】：Error while checking request.method检查 request.method 时出错

【问题描述】：

当我尝试做这样的 if 语句时：

if request.method == "POST":

我收到此错误：

AttributeError: 'module' object has no attribute 'method'

完整的追溯：

Traceback (most recent call last):

这是我的导入：

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from flask import Flask, request, render_template, flash, url_for, redirect, session
from flask_cors import CORS, cross_origin
from dbconnect import connection
from pymysql import escape_string as thwart
from passlib.hash import sha256_crypt
from functools import wraps
import random
from base64 import b64encode
from wtforms import Form, BooleanField, TextField, PasswordField, validators
import gc
from urllib import request

还有我的功能：

@app.route('/login', methods=['POST', 'GET'])
    def login_page():
        error = " "
        try:
            c, conn = connection()
            if request.method == "POST":

                data = c.execute("SELECT * FROM users WHERE username = (%s)", (thwart(request.form['username'])))
                print(data)
                if data < 1 :
                    return "0"
                else:
                    data = c.fetchone()[2]
                    if sha256_crypt.verify(request.form['password'], data):
                        session['logged_in']  = True
                        session['username'] = request.form['username']
                        return "1"
                    else:
                        return "0"

            gc.collect()

            return render_template("login.html")

        except Exception as e:
            raise e
            error = "Invalid credentials"
            return "error"

【问题讨论】：

你想做什么？检查正在使用来自request 的哪种方法？比如检查方法是否为request.method()?
您能在此处粘贴更多代码吗？使用这种方法的东西，以及任何导入语句都会很有用。
刚刚做了，添加了一些代码

标签： python python-3.x flask

【解决方案1】：

因为您要导入 2 个单独的 requests（来自 flask 和 urllib），所以它无法正常工作。将 urllib 请求的导入更改为此，并将 urllib 请求的所有引用从 request 更新为 req

from urllib import request as req
