This is a very similar problem to this question (Tornado POST 405: Method Not Allowed), but the dead simple answer for that question is still not working. There are also many, many more similar questions in the side bar -----> which are not related to Tornado, and did not provide me with a solution.
Right now I am using Firefox on OSX.
My tornado code is as follows:
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def post(self):
self.write("Hello, world")
get = post # <--------------
application = tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
application.listen(8888)
tornado.ioloop.IOLoop.instance().start()
If I run GET, it works fine, but if I use POST, I get the error on client side HTTP/1.1 405 Method Not Allowed
and the error on server side WARNING:tornado.access:405 OPTIONS
. I have tried running the js in both a file://index.html
and localhost:8000/index.html
setting
My test js looks like this:
//this one returns the error
U.Ajax.post("http://localhost:8888/", "text", "data = fez hat")
.then(function(result) {
console.log(result);
});
//this one works
U.Ajax.get("http://localhost:8888/", "text", "data = fez hat")
.then(function(result) {
console.log(result);
});
My ajax code looks like this, if that's any help:
//tested and functional ajax code, for ease of testing
U = {};
U.Ajax = {};
U.Ajax.send = function(getOrPost, url, dataType, data) {
return new Promise( function(resolve, reject) {
var request = new XMLHttpRequest();
if(getOrPost == "GET") {
request.responseType = dataType || "text";
request.open("GET", url);
}
else {//getOrPost == "POST"
request.open("POST", url);
request.setRequestHeader('Content-type', dataType)
}
request.onload = function() {
if (request.status >= 200 && request.status < 400) {
console.log("ajax", request.status+" "+url, request);
resolve(request);
} else {
request.onerror();
}
};
request.onerror = function() {
var err = "include src '"+url+"' does not exist";
console.log(err)
reject(err)
};
try {
request.send(data);
}
catch(e) {
var err = "NS_ERROR_DOM_BAD_URI: Access to restricted URI '"+url+"' denied";
console.log(err)
reject(err)
}
});
}
U.Ajax.get = function(url, responseType) {
return U.Ajax.send("GET", url, responseType);
}
U.Ajax.post = function(url, contentType, data) {
return U.Ajax.send("POST", url, contentType, data);
}
EDIT :: If I change the tornado code to equate GET POST and OPTION, it works, but incorrectly
class MainHandler(tornado.web.RequestHandler):
def post(self):
print(self.request)
get = options = post # <--------------
I no longer get an error, but when I print self.request
it appears that my headers are set to "OPTIONS" somehow
HTTPServerRequest(protocol='http', host='localhost:8888', method='OPTIONS', uri='/', version='HTTP/1.1', remote_ip='127.0.0.1', headers={'Origin': 'null', 'Accept-Language': 'en-US,en;q=0.5', 'Accept-Encoding': 'gzip, deflate', 'Access-Control-Request-Headers': 'content-type', 'Host': 'localhost:8888', 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8', 'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:55.0) Gecko/20100101 Firefox/55.0', 'Access-Control-Request-Method': 'POST', 'Connection': 'keep-alive'})
