我正在创建一个需要登录的烧瓶表单，登录后将进入带有复选框和文本输入的输入表单。
我面临一个特定的问题：我无法获取文本框的值，但无法获取复选框的值。
我使用flask并使用每种请求方法来打印我的文本框，但没有获取值。
下面是我的主文件代码：
from flask import Flask, render_template
import os
from flask import redirect, url_for, request
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"]="sqlite:////OtrsSummary.db"
app.config["SECRET_KEY"]="thisiskey"
db = SQLAlchemy(app)
# @app.route("/ndex")
# def home():
# names = os.getlogin().split(".")[0].title()
# return render_template("index.html", name=names)
@app.route("/welcome", methods=['GET', 'POST'])
def welcome():
if request.method=="POST":
try:
phase = request.form.get("phase")
rphase = phase.replace("on", "1")
print(rphase)
sale = request.form.get("sale")
rsale = sale.replace("on", "1")
print(rsale)
floor = request.form.get("floor")
rfloor = floor.replace("on", "1")
options = request.form.get("options")
roptions = options.replace("on", "1")

rimage = image.replace("on", "1")

rnpdeactivation = npdeactivation.replace("on", "1")

rconstuctionimages = constuctionimages.replace("on", "1")
brochure = request.form.get("brochure")
rbrochure = brochure.replace("on", "1")
rera = request.form.get("rera")
rrera = rera.replace("on", "1")
rticketnumber = request.form["ticketnumber"]##here not getting the value
rxidnumber = request.form["xidnumber"]##here not getting the value
rreranumber = request.form["reranumber"]##here not getting the value
print(rxidnumber)
print(rticketnumber)
msg = "Entry Submitted Successfully"
except AttributeError:
msg = "Please Do Not Submit Blank Form"
#con.close()
return render_template("same.html")
@app.route("/", methods=["GET", "POST"])
def log():
names = os.getlogin().split(".")[0].title()
error= None
if request.method == "POST":
if request.form["username"]!= os.getlogin() or request.form["password"]!="1234":
error = "Invalid Credentials.Please Try again."
else:
return redirect(url_for("welcome"))
return render_template("index.html", error=error, name=names)
app.run(debug=True)

有人可以提出一些解决方案吗？
答案 0 :(得分：0)
实际上，我尝试运行您的代码，并且只有选中所有上述复选框，我才会获取文本框的值。
实际上，您正在捕获属性异常，但没有正确处理它。在您的代码中，如果未选中任何复选框，则会给出异常'NoneType'对象没有属性'replace '。不会被处理，因此将不会执行下一行代码。
我对使用复选框的建议是使隐藏类型具有相同的名称，并且值='off'，因此，如果未选中它，则会给出off值。
<input type='hidden' name="checkbox_name" value="off">

request.form 是一本词典，因此您可以检查您的复选框是否已被选中：
sale = 'checked' if 'sale' in request.form else 'not_checked'
