Like in the title. I have a problem with recieving logged user data under vuejs.
I use
- FOS User - to login
- Fos Rest - to api
- Jms Serializer
This is my function to take data from database
public function getUser()
{
$userId = $this->container->get('security.token_storage')->getToken()->getUser('id');
return $this->repository->FindOneBy(['id' => $userId]);
}
Now, when it is in form like above, console.log return an empty object, in vuejs. However, when I change $userId to 5 for example -
$this->repository->FindOneBy(['id' => 5]);
object is available with data.
now. I checked api addres in both cases - works. i also return a dump in both cases. everything in both cases is identical.
this is my log
when $userId
127.0.0.1 - - [07/Apr/2018:03:55:24 +0200] "GET /ekopanel2/web/app_dev.php/api/v1/greenker/user HTTP/1.1" 204 380 "http://localhost:8080/greenker" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0"
and this is when 5
127.0.0.1 - - [07/Apr/2018:03:55:34 +0200] "GET /ekopanel2/web/app_dev.php/api/v1/greenker/user HTTP/1.1" 200 895 "http://localhost:8080/greenker" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0"
i noticed that status code is different, when 5 it is 200 and working, when $userId, status code is 204, so it looks like it gets empty data.
Can you help please?
Let's suppose you are logged in.
If not, $this->container->get('security.token_storage')->getToken()->getUser() would return the string "anon."
Have you tried with this :
$userId = $this->container->get('security.token_storage')->getToken()->getUser()->getId();
Be carefull to check if the user is logged in. Otherwise, it will throw an exception like "Call to a member function getId() on string".

Below is the request that I did. Everything works except when I try the put /stats-batch which shows this error. I don't know what is the options that is being displayed, I only noticed it today.
The /stats-batch also just prints hello when access

I call this functions with a button click using axios like this. config has the authorization header just like all the other request
const startBatch = async () => {
const status = 'start'
await axios
.put('http://127.0.0.1:5000/stats-batch', status, config)
.then((res) => {
console.log(res)
})
.catch((err) => {
console.log(err)
})
}
The console shows the error that No Access-Control-Allow-Origin header is present on the requested resource.
I also have flask_cors installed and the other axios request is working. I don't know what cause this error if its the backend or the frontend.
I see an issue; "/new-batch" endpoint is throwing 500 exceptions, which could be related to "Object of type function is not JSON serializable".
Based on the description / Error "No Access-Control-Allow-Origin header is present on the requested resource" message what I understand is
CORS configuration has been missed for PUT VERB.
Because you wrote that rest of the endpoints work without issues, only PUT on this specific "/new-batch" endpoint fails.
Options: In CORS, a preflight request is sent with the OPTIONS method so that the server can respond if it is acceptable to send the request.

Hi I am trying to do SSE(Server-Sent Events) with python flask quite similar to this question
I am using SSE to plot a real-time graph in the web app.
My codes are working fine when applied in local, but when I deploy it in GAE(Google App Engine), the data does not seem to be returned(yield)
I found that I should make the response header as following
X-Accel-Buffering: no
in this guide here
So, I tried this code on "main.py"
# render "plot.html" and plot the real-time graph
# plot.html gets the value from /chart-data event stream, and update the graph
#app.route('/plot_graph', methods=["GET", "POST"])
def plot_graph():
return render_template('plot.html')
#app.route('/chart-data')
def chart_data():
def generate_random_data():
while True:
# generating random data
json_data = json.dumps(
{'time': datetime.now().strftime('%Y-%m-%d %H:%M:%S'), 'value': random() * 100})
yield f"data:{json_data}\n\n"
time.sleep(0.5)
resp = Response(generate_random_data(), mimetype='text/event-stream')
resp.headers["X-Accel-Buffering"] = "no"
return resp
Also, in "plot.html" file, it is getting values from /chart-data like this
const source = new EventSource("/chart-data");
source.onmessage = function (event) {
const data = JSON.parse(event.data);
...
}
and this also works well when executed in local machine, but not working on GAE..
for the logs and error messages, when I tried the code on local machine,
and went to the root dir, /plot_graph, /chart-data, the log looks like
127.0.0.1 - - [03/Jul/2020 14:14:19] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [03/Jul/2020 14:14:20] "GET /favicon.ico HTTP/1.1" 404 -
127.0.0.1 - - [03/Jul/2020 14:14:23] "GET /plot_graph HTTP/1.1" 200 -
127.0.0.1 - - [03/Jul/2020 14:14:24] "GET /chart-data HTTP/1.1" 200 -
127.0.0.1 - - [03/Jul/2020 14:15:04] "GET /chart-data HTTP/1.1" 200 -
when I went into /plot_graph, I see a GET request from /chart-data and it works fine(/plot_graph shows a real-time graph). Also, when I go into /chart-data, I can see yielded values being displayed on the web.
In the GAE logs,
2020-07-03 05:22:23 default[20200703t141524] "GET / HTTP/1.1" 200
2020-07-03 05:22:23 default[20200703t141524] "GET /favicon.ico HTTP/1.1" 404
2020-07-03 05:22:38 default[20200703t141524] "GET /plot_graph HTTP/1.1" 200
for the GAE, even if I entered /plot_graph, the GET request does not seemed to be happening. and since it is not getting any values, the graph is not plotted(only the frame for the graph is displayed).
Also, I tried to go into /chart-data of GAE web server, but I could not enter and cannot see any GET request in the logs as I saw on the server on local machine.
Please can you help me with this problem?
I'm creating a database for a school project and doing the backend between it and the app.(I'm using Flask and SQLAlchemy for it)
So the problem is that i can't call a function User(entrances), the function User() is a construction function used to create and object ,well it's what it looks like for me at least. But the function itself works when i do it in the interpreter.
WHY can i do it in my interpreter and can't do it on the flask tiny web framework???
here's the github link:BackEndRepository
Before taking a look at the samples here's the output form the interpreter that works:
Interperter
here's the code for my route:
from app import app,db
from models import User
from flask import render_template,Flask,request,redirect,url_for
#app.route('/index')
def index():
return "Hello, World!"
#app.route('/teste')
def teste():
users = db.session.query(User).all()
return u"<br>".join([u"{0}: {1}".format(user.name, user.email) for user in users])
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste
And here is the code for my model:
from app import db
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(64), index=True, unique=True)
email = db.Column(db.String(120), index=True, unique=True)
def __init__(self,name,email):
self.name = name
self.email= email
def __repr__(self):
return '<User {0} {1}>'.format(self.name,self.email)
so i run in my terminal "flask run" and get the error in response:(theese is all the log i had after doing what i explained)

TypeError: 'User' object is not callable
The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a User.

JUST highlighting the part that's bugging me out the most here:
TypeError: 'User' object is not callable
The problem is here:
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste
You are returning teste which is a User. That's not a valid return type here as the error tells you:
The return type must be a string, tuple, Response instance, or WSGI callable, but it was a User.
It's fine to return a string for example, so this should work:
#app.route('/teste2')
def teste2():
teste=User(name='susan',email='susan#example.com')
#u = User(name=request.args.get('1'), email=request.args.get('2'))
return teste.name
I'm looking for a way to get the ip address with camel rest dsl and the Netty4 Http component.
I checked on the documentation, I've put a breakpoint on my rest and checked on the headers, the properties,...everywhere, and couldn't find a proper way get this information.
Headers log:

You should get two headers populated:
CamelNettyLocalAddress and CamelNettyRemoteAddress.
See here where the debug log of netty-http shows this clearly.

I have some hard time with my code. I'm trying to connect to a website using cURL.
Let's see the code of the website :
<td class="input "><input tabindex="1" class="text" name="authentificationLogin" id="authentificationLogin" type="text"/></td>
<td class="input "><input tabindex="2" class="text" autocapitalize="off" autocorrect="off" name="authentificationPassword" id="authentificationPassword" type="password"/></td>
<td class="input "><input name="authentificationRedirection" id="authentificationRedirection" type="hidden" value="http://myWebsite/?Redirect"/><input name="authentification08e11696a1" id="authentification08e11696a1" type="hidden" value=""/><br/><button class="button button-style" type="submit" name="Submit" id="authentificationSubmit" onclick="return lock("id:authentificationSubmit");">
Now, let's see my code :
#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>
#include <curl/curl.h>
#include <curl/easy.h>

Well, that start to be interessant. This is cookies sent to the website during the HTTP request. They changed each time I sent a new HTTP request.
&to=gaia&login=myName&password=myPassword&redirection=http%3A%2F%2FmyWebsite.com%2%2F%3Fidentification%3D1&isBoxStyle=&08e11696a1=
This is the principal of my request. Name and password are sent to the server.
I have no error but my code is not working because my hour of last connection isn't change... Probably because i don't set cookies.
I'm really inexperienced and I know I'm doing probably so many stupid error. But, please, if you have any informations, answer to my question...
Have you some genious ideas for repair this code ?
Best regards.
Xavier.
You want to set the string "&to=gaia&login=myName&password=myPassword&redirection=http%3A%" ... to the CURLOPT_POSTFIELDS option for such a "regular" POST.
The CURLOPT_HTTPPOST option that you use (in combination with curl_formadd etc) is for multipart formposts, which you obviously don't want!
I'm happy to told you that i finally did it.

If you have probleme, do no hesitate to post, and i will try to help you :)
It is the answer to connect to the website, you can also look what i sniffed to have an example ;)
