Flask在POST方法上不重定向

from flask import Flask, redirect, request

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        # 处理POST请求的逻辑
        return redirect(request.url)
    else:
        # 处理GET请求的逻辑
        return 'Hello, Flask!'

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

from flask import Flask, render_template, request

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    if request.method == 'POST':
        # 处理POST请求的逻辑
        data = request.form.get('data')
        return render_template('index.html', data=data)
    else:
        # 处理GET请求的逻辑
        return render_template('index.html')
