I have problem with Telegram Bot Api and with "ReplyKeyboard". I'm using Python 2.7 and I send post request: TelegramAPI.post(TELEGRAM_URL + "sendMessage", data=dict(chat_id=CHAT_ID, text="", keyboard={'keyboard': keyboard, 'one_time_keyboard': False, 'resize_keyboard': True}) keyboard in this format: [["A button"], ["B button"]] But in Telegram I don't see keyboard. What problem can be? According to the Bot API documentations , a custom keyboard requires a reply_markup parameter, whose value is a JSON-serialized specification of the keyboard. Assuming your TelegramAPI.post() function does not

For some reason, I am not able to use post methods in torando. Even the hello_world example does not work when I change get to post. import tornado.ioloop import tornado.web class MainHandler(tornado.web.RequestHandler): def post(self): self.write("Hello, world") application = tornado.web.Application([ (r"/", MainHandler), ]) if __name__ == "__main__": application.listen(8888) tornado.ioloop.IOLoop.instance().start() It throws 405 method not allowed. Any suggestions ? You still need get if you want access the page, because access the page using browser request with GET method. import tornado

When to use RequestHandler.get_argument() , RequestHandler.get_query_argument() and RequestHandler.get_body_argument() ? What is the use-case for each of them? Also what does the request.body and request.argument do in these cases? Which are to be used in which scenarios? And, is there a request.query or something similar too? Most HTTP requests store extra parameters (say, form values) in one of two places: the URL (in the form of a ?foo=bar&spam=eggs query string ), or in the request body (when using a POST request and either the application/x-www-form-urlencoded or multipart/form-data mime

first, here is what is said in Pymongo Documentation By default, PyMongo starts a request for each thread when the thread first runs an operation on MongoDB. This guarantees **read-your-writes consistency . Within a request, the thread will continue to use the same socket exclusively, and no other thread will use this socket, until the thread calls end_request() or it terminates. At that point, the socket is returned to the connection pool for use by other threads. so when using an async library to Mongodb (like Asyncmongo, Motor), will the user have a consistency like the one in blocking

简单的web services： 现在我们将开始了解什么是tornado，tornado可以做什么。我们来通过分析tornado实现的一个简单web service 例子开始吧。 Hello Tornado tornado 是一个可以处理http请求的框架，你的工作是作为一个程序员，编写一个handlers来响应一个标准的http请求。，下面是这个例子的所有代码： 范例1:hello.py Code View Copy Print import tornado.httpserver import tornado.ioloop import tornado.options import tornado.web from tornado.options import define, options define(“port”, default=8000, help=”run on the given port”, type = int ) class IndexHandler(tornado.web.RequestHandler): def get ( self ): greeting = self .get_argument(‘greeting’, ’Hello’) self . write (greeting + ’, friendly user !’) if __name__ =
