我正在尝试使用FLASK完成一个外汇货币转换器，但是我的代码无法正常工作。
它允许用户输入，然后在我点击后提交显示Method Not Allowed的下一页
所请求的URL不允许使用该方法。
-Update，现在只要我尝试拉起不加载的Index2.html，它就会转到操作页面。我不确定为什么它不允许我继续进行。
-我正在尝试保存三个输入，将它们添加到列表中，然后将其转换为美元金额
-Page刷新到操作页面，这不是预期的

最佳答案
由于未共享index2.htlm，因此我创建了一个简单的1衬板index2.html来显示转换。 PFB代码:
app.py:
from flask import Flask, render_template, request, redirect, session, url_for
from forex_python.converter import CurrencyCodes, CurrencyRates
app = Flask(__name__)
app.config["secret key"] = "yeah"
app.config['DEBUG_TB_INTERCEPT_REDIRECTS'] = False
responses_key = "responses"
@app.route('/', methods = ['GET', 'POST'])
def index():
return render_template('Index.html')
T = CurrencyRates()
@app.route("/conversion", methods = ['GET', 'POST'])
def conversion():
if request.method == 'POST':
C1 = request.form.get('C1', None)
C2_to = request.form.get('C2_to', None)
amt = request.form.get('amt', None)
rate = T.convert(C1, C2_to, int(amt))
print(C1, C2_to, amt, rate)
details = {'C1': C1, 'C2_to': C2_to, 'amt': amt, 'rate': rate}
return render_template("Index2.html", details=details)
if __name__ == '__main__':
app.run(host='xx.xx.xx.xx', debug=True)
app.run(debug=True)
