kandi X-RAY | client-examples Summary
This repository contains examples of Apache Kafka clients written using the Apache Kafka Java APIs:. All examples are assembled into Docker images which allows them to be deployed on Kubernetes or OpenShift. This may serve as a basic usage example for the Strimzi project. This repository contains Deployments for the clients as well as KafkaTopic and KafkaUsers for use by Strimzi operators. Logging configuration can be found in the log4j2.properties file for the producer and consumer separately.

QUESTION
I'm sending post request from "angular->port 4200" to "expressjs server->port 8000".
As an example i'm folowing this example: https://github.com/kuncevic/angular-httpclient-examples/blob/master/client/src/app/app.component.ts
I'm getting two error :
1)undefined from Nodejs(data and req.body.text)
2)Message received from background. Values reset
Angular side:
...ANSWER
Answered 2022-Feb-07 at 07:14Either you are not sending anything of there is no value in body.text
Try to console.log(req.body)
instead of req.body.text
.
Try to console.log(culture)
and this.getLangCookie()
on the client side to see if you are actually sending something.
You can also make use of the network tab in the browser to inspect the request that you are sending.
QUESTION
I'm trying to use D1 mini to fetch some data from website. I created an API key on Thingspeak ThingHttp. However, the client didn't connect properly. I got "connection failed" from the Serial monitor.
Here is my code. I think they are almost the same as this.
...ANSWER
Answered 2021-Jul-26 at 05:27You're using the wrong port number.
Port 80 is for unencrypted HTTP.
Port 443 is for HTTPS.
You're using WiFiClientSecure
, so presumably you're intending to use HTTPS. HTTPS runs on port 443, not port 80. You'll need to change your code to use 443, or you'll need to use WiFiClient
in order to work with port 80 (but make sure the API you're trying to connect to allows access over plain HTTP - most will not).
I highly recommend that you use an existing HTTP client rather than implement the protocol yourself as you'll need to with WiFiClient
or WiFiClientSecure
, which just provide TCP and encrypted TCP connections. You can find examples of how to use ESP8266HTTPClient
in the ESP8266 Arduino core repository.
QUESTION
I followed ManagedSubscriptionDataExample.java (https://github.com/eclipse/milo/blob/master/milo-examples/client-examples/src/main/java/org/eclipse/milo/examples/client/ManagedSubscriptionDataExample.java) example on github page to read OPC nodes from PLC S7-1200.
Value for nodes are getting updated but I can't get name.
For code:
...ANSWER
Answered 2021-Nov-05 at 13:58UaExpert is doing more bookkeeping than you are doing. You should have knowledge of which Nodes you have created MonitoredItems for and be able to get the BrowseName or DisplayName attribute from those Nodes.
Inside that callback you have access to the NodeId - that should be your key to get to the Node and any attributes you are interested in.
QUESTION
I would like to ask how should I work correctly with Struct when I am trying to read some object from opc ua server. I went trough this example and I was able to read the data.
But right now I don't know how to correctly read them. Let's imagine I am reading some datastructure including two arrays for x and y values. I tried to do something like this:
...ANSWER
Answered 2020-Nov-23 at 08:19First of all, you cannot cast array of objects like that. Instead, you could use the stream API to construct Floats like this:

I was following the steps in https://www.eclipse.org/hono/docs/dev-guide/java_client_consumer/ to start the example Hono client. From the hono-client-examples folder I ran this command -
...ANSWER
Answered 2020-Aug-21 at 14:56Assuming that you are running Hono on a local minikube cluster with minikube tunnel
running, you can determine the IP address and port of Hono's northbound API as follows (replace hono
with the namespace that you have installed Hono to):

I am following the "4. Java Socket Client Example: a HTTP Client" instruction from https://www.codejava.net/java-se/networking/java-socket-client-examples-tcp-ip in my Mac using IntelliJ.
The Http config is as easy as:
...ANSWER
Answered 2020-May-04 at 08:39The issue is how new lines are printed on Windows and Mac, Windows treats new lines as 2 characters, CR - Carriage return ("\r") + LF- Line feed ("\n") "\r\n"
, Mac prints new lines as LF("\n")
only. HTTP requests expects each line to be separated by CRLF "\r\n"
, what your code is printing is just "\n"
on Mac and "\r\n"
on Windows that is why it works as expected on Windows platform.
To make it work on both Windows and Mac try the following code:
