405 方法不允许,methods=["POST", "GET"] 不工作
405 Method not Allow, methods=["POST", "GET"] not working
我在网上学习 flask 教程,也在看 POST 和 GET 上的视频。其中一个练习是 运行 一个简单的表单提交,在新的 @app.route() 上返回用户名。我尝试添加密码和用户名来模拟登录,因为我认为我很酷但失败了。代码如下。
from flask import Flask, redirect, url_for, render_template, request
app = Flask(__name__)
realUser: str = "name"
realPass: str = "pass"
@app.route("/")
def home():
return render_template("extension.html")
@app.route("/login", methods=["POST", "GET"])
def login():
if request.method == "POST":
user = request.form["un"]
password = request.form["password"]
if realUser == user and password == realPass:
return redirect(url_for("user", usr=user))
else:
return render_template("extension.html")
@app.route("/<usr>")
def user(usr):
return f"<h1>{usr}</h1>"
if __name__ == "__main__":
app.run(debug=True)
extension.html:
{% extends "ThePurpleLounge.html" %}
{% block title %}Home Page{% endblock %}
{% block content %}
<h1>Login</h1>
<form method="post">
<p>Name:</p>
<p><input type="text" name="un" /></p>
<p>Password:</p>
<p><input type="text" name="password" /></p>
<p><input type="submit" value="submit" /></p>
</form>
{% endblock %}
ThePurpleLounge.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{% block title %}{% endblock %}</title>
</head>
<body>
{% block content %}
{% endblock %}
</body>
</html>
我什至尝试将我的代码简化为:
from flask import Flask, redirect, url_for, render_template, request
app = Flask(__name__)
@app.route("/")
def home():
return render_template("extension.html")
@app.route("/login", methods=["POST", "GET"])
def login():
if request.method == "POST":
user = request.form["un"]
return redirect(url_for("user", usr=user))
else:
return render_template("extension.html")
@app.route("/<usr>")
def user(usr):
return f"<h1>{usr}</h1>"
if __name__ == "__main__":
app.run(debug=True)
但是,它仍然显示 405 Method Not Allowed。本教程直接进入代码,所以我可能必须安装或配置一些东西。
在 @app.route("/")
中您不允许使用 POST 方法。因此,当您尝试发送带有 url http://127.0.0.1:5000/ 的表单时,服务器会拒绝它。
但是,如果您纠正存在另一个问题:您在另一个 url (@app.route("/login", methods=["POST", "GET"])
).
处实现了登录方法
这是您的代码的有效修改(/
重定向到 /login
)
from flask import Flask, redirect, url_for, render_template, request
app = Flask(__name__)
realUser: str = "name"
realPass: str = "pass"
@app.route("/")
def home():
return redirect(url_for("login"))
@app.route("/login", methods=["POST", "GET"])
def login():
if request.method == "POST":
user = request.form["un"]
password = request.form["password"]
if realUser == user and password == realPass:
return redirect(url_for("user", usr=user))
else:
return render_template("extension.html")
@app.route("/<usr>")
def user(usr):
return f"<h1>{usr}</h1>"
if __name__ == "__main__":
app.run(debug=True)
这种代码对于理解 flask 的工作原理很有趣。要进一步了解身份验证方法,您应该看看 。
