Good question. I wanted to encapsulate the C API for socket programming and make it more modern. So far, I did not really succeed, I guess. There is one cool thing at the moment: Requests are handled by specifying an arbitrary function object (yay, C++11). This function is then called asynchronously (yay, C++11 again!) whenever a new client is accepted. You can then send stuff to the client or whatever...

QUESTION
I'm trying to follow a tutorial about creating and hosting an HTTP proxy. When I try to install the modules, it fails. (SimpleHTTPServer and SocketServer)
Tutorial used: https://levelup.gitconnected.com/how-to-build-a-super-simple-http-proxy-in-python-in-just-17-lines-of-code-a1a09192be00
Output:
...ANSWER
Answered 2022-Jan-17 at 21:23Those are standard library's modules as LeopardShark mentioned. You can import them directly to your code without installing them with pip.
The complete list of modules coming with standard library you can find here: https://docs.python.org/3/library/
Also, the specific modules you're asking about were renamed in Python3:
Note The SimpleHTTPServer module has been merged into http.server in Python 3.
Based on module's documentation: https://docs.python.org/2/library/simplehttpserver.html
Basically, you just need to do:

I have a socket server, so it is looping forever and check whatever data received on the socket. If b'Go' command is received on the socket connection, I want to start another loop that prints "Going ..." every 5 seconds. If b'Stop' command is received on the socket connection, I want to start another loop that prints "Sitting ..." once. Then the socket connection keep listening.
I tried the following but now blocked. Thanks for help.

QUESTION
I am attempting to log message via log4cplus::SocketAppender
. These messages are serialized using google protobuf.
I have no problem sending logs with small size. However, if I attempt to log messages with character length greater than 8000, I get following error message:
log4cplus:ERROR SocketBuffer::appendString()- Attempt to write beyond end of buffer
My current workaround is breaking these buffers into smaller chunks before sending it across the network.
Here is a snippet of my property file (named test.properties):
...ANSWER
Answered 2021-Feb-23 at 06:42If your MyBuffer
is binary data then you are using log4cplus wrong. It is meant to log text strings, not binary data.
Also, there is a limit to the length of a buffer to 8*1024
bytes. See socketappender.h
.
QUESTION
I have a Phoenix Framework app deployed with Cloud Run with multiple clients using it.
I want to move the deployment to Computer Engine because of Cloud Run background task limitation, but I don't want to force clients to update their apps (i.e. backend url).
So I though I could deploy a Ngnix instance in Cloud Run that redirects everything to Compute Engine.
The problem is that I use an authorization request header that does not reach Phoenix connection. I've tried it with a different server (a Python simpleserver) and it receives every header properly.
So, the question is. Does Phoenix Framework filters out some request headers if they come from a redirection?
The header is:
{"authorization", "Bearer XXX"}
ngixn.conf is simply:
...ANSWER
Answered 2020-Nov-03 at 10:07This is a feature in curl. If a request gets redirected to a different hostname, then any Authorization
header is going to be removed in the second request in order not to leak credentials to an unrelated server. (You're making a request to localhost:80
, but the redirect location is 0.0.0.0:4000
, so that counts as a different hostname.)
You can get curl to forward the Authorization
header by using the --location-trusted
option instead of -L
.
(Though it's odd that you're seeing this with curl 7.54.0 - according to this security advisory, curl 7.54.0 should behave as you expect it to, and only 7.58.0 and higher have this protection feature.)

QUESTION
I have to insert this code:
...ANSWER
Answered 2020-Jul-19 at 20:45The program starts creating a socket and setting it to listen to a specific port, passed as an argument to your program with a command line such as programName
.
The port number is retrieved with the line simplePort = atoi(argv[1]);
. There could have been a stricter check on the parameter (atoi()
doesn't check if a number is actually provided), but I suppose it is ok for an entry level educational program.
After that, with the line

QUESTION
I would like to integrate an HTML5 microphone in my web application, record audio and send it to a (Node.js) back-end, use the Dialogflow API for audio, and return audio result to a client to play this in a browser.
(I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )
I found a github project which is exactly what I want to do. https://github.com/dialogflow/selfservicekiosk-audio-streaming
This is Ms. Lee Boonstra's Medium blog. (https://medium.com/google-cloud/building-your-own-conversational-voice-ai-with-dialogflow-speech-to-text-in-web-apps-part-i-b92770bd8b47) She has developed this project. (Thank you very much, Ms. Boonstra!) She explains this project very precisely.
This project contains selfservicekiosk application and 6 simple examples. I tried all of them. selfservicekiosk application and simple example 1,2, 4,5,6 worked perfectly, but example3 didn't work. Unfortunately, example3 is what I want to do. https://github.com/dialogflow/selfservicekiosk-audio-streaming/tree/master/examples
These are results when I tried example3.
This is Terminal. This is Chrome's console.
I focus on this message.
...ANSWER
Answered 2020-May-15 at 13:22Hmm that is strange because I did clone a fresh repo, on my Windows 10 machine (without changing the code), and tested it with Chrome (79.0.3945.130) and it just worked. The problem for you is indeed the playing part, because your browser did receive an audio buffer.
Since you mentioned that the SelfServiceKiosk app worked, and example 3 not; maybe you could replace the playOutput function with the function that is been used by the SelfServiceKiosk app? You can find it here, but be aware that the code is written in TypeScript.
https://github.com/dialogflow/selfservicekiosk-audio-streaming/blob/master/client/src/app/dialogflow/dialogflow.component.ts
I know that this code is a little different, and i think I have wrote it that way that it resumes and starts, because otherwise IOS seems to block the auto play. Hope that helps?
