Question

我正在构建一个Web应用程序，并尝试使用redirect（）函数链接两个html。但是，当我单击“提交”按钮时，login.html不会重定向到success.html（即浏览器仍在login.html中）

下面是我的python代码：

from flask import Flask, redirect, url_for, render_template, request, abort
app = Flask(__name__)

@app.route('/')
def index():
   return render_template('login.html')

@app.route('/login',methods = ['POST', 'GET'])
def login():
   if request.method == 'POST':
      if request.form['username'] == 'admin':
         return redirect(url_for('success'))
      else:
         abort(401)
   else:
      return redirect(url_for('index'))

@app.route('/success', methods = ['POST', 'GET'])
def success():
   return 'logged in successfully'

if __name__ == '__main__':
   app.run(debug = True)

还有html代码：

<html>
   <body>
      <form action = "login" method = "post">
         <p>Enter Name:</p>
         <p><input type = "text" name = "username" /></p>
         <p><input type = "submit" value = "submit" /></p>
      </form>
   </body>
</html>

Answer 1

您的字段名称在html和view函数中不匹配。将name = "nm"更改为name = "username"：

<html>
   <body>
      <form action = "login" method = "post">
         <p>Enter Name:</p>
         <p><input type = "text" name = "username" /></p>
         <p><input type = "submit" value = "submit" /></p>
      </form>
   </body>
</html>

当Flask中的request.method =='POST'时Redirect（）不起作用
