注意:我不知道其他帖子是如何回答这个问题的。我确实发现了以下内容:
如果你想打印到浏览器，你可以添加:
return jsonify(request.form)
如果你想打印到控制台你可以添加:
my_data = request.form
for key in my_data:
print ('form key '+key+" "+my_data[key])
return render_template("some.html")
我正在尝试使用以下 Controller 打印所有 POST 变量:
from flask import Flask, render_template, request
app = Flask(__name__)
@app.route("/")
def index():
return render_template("index.html")
@app.route("/register", methods=["POST"])
def register():
dict = request.form
for key in dict:
print ('form key '+dict[key])
但是我得到了错误:
ValueError: View function did not return a response
这是我的表格:
{% extends "layout.html" %}
{% block title %}
Frosh IMs
{% endblock %}
{% block body %}
