如何使用Flask将POST传递到另一个URL [英] How to pass your POST to another URL using Flask
问题描述
我正在尝试从用户那里获取一些短语，当他/她按下提交"时，我想使用Flask将他/她重定向到具有他/她名字的另一个页面.这是我的Python代码:
I am trying to get some phrase from the user, and when he/she will press "submit" i want to redirect him/her to another page with his/her name, using Flask. Here is my Python code:
from flask import Flask, redirect, render_template, request, session, url_for
app = Flask(__name__)
@app.route("/", methods = ["POST", "GET"])
def login():
if request.method == "POST":
user = request.form["name"]
return redirect(url_for("success", name=user))
else:
return render_template("login.html")
@app.route("/success", methods = ["POST", "GET"])
def success():
user = request.form.get('name')
return render_template("success.html", name=user)
if __name__ == "__main__":
app.run("0.0.0.0", 8080)
因此，当我转到自己的网站时，我将转到"else"分支并执行:"render_template("login.html")".然后，如果我按提交，我进入如果"，我试图将用户重定向到"success.html".这是我的login.html:
So when i go to my site i am going to "else" branch and do: "render_template("login.html")". Then if i press submit i go into "if" where i am trying to redirect the user to "success.html". Here is my login.html:
<html>
<body>
<form action = "http://ide50-zahar-zagrava.cs50.io:8080/" method = "post">
<p>Enter Name:</p>
<p><input type = "text" name = "name" /></p>
<p><input type = "submit" value = "submit" /></p>
</form>
</body>
</html>
和succes.html:
And succes.html:
<html>
<body>
<h1>Hello {{ name }}!</h1>
</body>
</html>
但是有话要说:你好"，它说:你好，没有".我的主要问题是如何将数据从一页传递到另一页?我对Flask和Python完全陌生，所以我不知道出了什么问题.
But insted of saying: "Hello " it says: "Hello None". My main question is how to pass data from one page to another? I am completely new at Flask and Python, so i can't figure out what's going wrong.
推荐答案
form 中的 action 错误.您正在将表单发送到索引页面.您可以像这样编辑它:
your action from form is wrong.you are sending the form to the index page. you could edit it like:
<form action="{{ url_for('success') }}" method="post">
这样，您的表格将被发送到成功方法.
this way, your form will be sent to the success method.
