Flask - POST - The method is not allowed for the requested URL
提问by Phil27
I just started learning Flask but I meet troubles with the POST method.
我刚开始学习 Flask，但在使用 POST 方法时遇到了麻烦。
Here is my (very simple) Python code :
这是我的（非常简单的）Python 代码：
@app.route('/test')
def test(methods=["GET","POST"]):
if request.method=='GET':
return('<form action="/test" method="post"><input type="submit" value="Send" /></form>')
elif request.method=='POST':
return "OK this is a post method"
else:
return("ok")
when going to : http://127.0.0.1:5000/test

I successfully can submit my form by clicking on the send button but I a 405 error is returned:

You gotta add "POST" in the route declaration accepted methods. You've put it in the function.
您必须在路由声明接受的方法中添加“POST”。你已经把它放在函数中了。
@app.route('/test', methods=['GET', 'POST'])
def test():
if request.method=='GET':
return('<form action="/test" method="post"><input type="submit" value="Send" /></form>')
elif request.method=='POST':
return "OK this is a post method"
else:
return("ok")
