trying to understand how to work with kryonet, it is quite easy to send and receive message from java client, but what if I want to send it from some UI tool like Hercules, or not java code. As I see it uses kryo for Serialization, is there way to serialize object to this fromat without java? Or use plain String or json for comunication?
You can easily create a server using json instead of kryo:
import com.esotericsoftware.kryonet.Server;
import com.esotericsoftware.kryonet.serialization.JsonSerialization;
new Server(16384, 2048, new JsonSerialization());

I'm trying to utilise com.google.cloud.dialogflow.v2.WebhookResponse to interact with my dialogflow agent. But I'm having trouble responding back to the agent during fulfillment.
The response created doesn't follow the specifications required i.e the agent expect the json to be fulfillmentText: "something" but the builder builds it in the format of fulfillment_text. There's not enough documentation on how to use API client correctly
Anyone has experience doing this in java/kotlin?
val response = WebhookResponse
.newBuilder()
.setFulfillmentText("Hello")
.build()
println(response)
println(Gson().toJson(response))
Output:
fulfillment_text: "Hello"
{"bitField0_":0,"fulfillmentText_":"Hello","fulfillmentMessages_":
[],"source_":"","outputContexts_":[],"memoizedIsInitialized":1,"unknownFields":{"fields":{}},"memoizedSize":-1,"memoizedHashCode":0}
I'm using 'com.google.cloud:google-cloud-dialogflow:0.75.1-alpha' from https://cloud.google.com/dialogflow-enterprise/docs/reference/libraries/java
The library you're using is primarily designed as a client library, letting you send text to Dialogflow and having it determine the Intent and parameters (and possibly a response) from that text.
It sounds like you're trying to use this on the other end - in a webhook to handle fulfillment. It just isn't designed for that. The Class was automatically generated from the ProtoBuf definition, which does not serialize to JSON, and isn't designed to represent things that way.
You will need to build the JSON for the response yourself.
I want to send a client's public key (java.security.publickey) in JSON format to my server. I'm using Google's Gson library to convert in between, however, I'm getting a runtime exception which tells me that Key is an interface and I need some kind of adapter to parse it. Have anyone encountered this problem? Any solution is welcome, I just need to transfer the key via HTTP.
Thank you!
You can get the encoded key using the getEncoded() method and send that via JSON to your server.
I'm using Netty Socket IO to send socket.io content from Java (well, actually Scala.) I've tried several ways of sending a JSON object to the client:
hardcoded String
standard Java json library
Gson library
Each time, when the data gets to the client, it's just a string that looks like a JSON object. I'm currently sending it with:
case class Data(message:String) and gson.toJson(new Data("what up")). The object looks like this on the client: "{"message":"what up"}", although it's just a String and not a JSON object.
Any ideas on how to get an actual JSON object on the other side?
Thanks
This works (JQuery):
$.parseJSON(string)
I need to use some from from a php web service which rendering its data by serializing json in java play framework 1.2.x. What i am doing just using play WS function. and i am getting data from that service. But when I try to get it with JSONObject it throws excepiton which is so normal, because the returned data does not look a json format well. Any body who knows any workarounds or solution would be appreciated.
HttpResponse htp = WS.url("http://www.geoplugin.net/php.gp?ip=78.171.90.49").get();
System.out.println(htp.getContentType()+"\n"+htp.getStatusText()+"\n"+htp.getString());
The returned data :
a:18:{s:17:"geoplugin_request";s:12:"78.171.90.49";s:16:"geoplugin_status";i:200;s:16:"geoplugin_credit";s:145:"Some of the returned data includes GeoLite data created by MaxMind, available from <a href=\'http://www.maxmind.com\'>http://www.maxmind.com</a>.";s:14:"geoplugin_city";s:8:"Istanbul";s:16:"geoplugin_region";s:8:"Istanbul";s:18:"geoplugin_areaCode";s:1:"0";s:17:"geoplugin_dmaCode";s:1:"0";s:21:"geoplugin_countryCode";s:2:"TR";s:21:"geoplugin_countryName";s:6:"Turkey";s:23:"geoplugin_continentCode";s:2:"EU";s:18:"geoplugin_latitude";s:7:"41.0186";s:19:"geoplugin_longitude";s:9:"28.964701";s:20:"geoplugin_regionCode";s:2:"34";s:20:"geoplugin_regionName";s:8:"Istanbul";s:22:"geoplugin_currencyCode";s:3:"TRY";s:24:"geoplugin_currencySymbol";s:15:"YTL";s:29:"geoplugin_currencySymbol_UTF8";s:3:"YTL";s:27:"geoplugin_currencyConverter";s:6:"2.2669";}
You are accessing the PHP endpoint. You need to hit this URL instead:
http://www.geoplugin.net/json.gp?ip=78.171.90.49
I have some forms and databases that will fill up some POJO's with data. Using Json (gson) I"m going to upload the data to my web server. The server will send back a responses that will eventually be placed back in objects.
My question is, should I encode/decode my objects to json and then pass strings back and forth to my WebApi class? Or should I pass my WebApi class my object and have it pass back an appropriate response object (based on the method I call.)?
So at when I call my Api that has all the http conection stuff in it, it would look something like this.
myWebApi postSomeData( jsonData ); //
Should jsonData be a pojo that will be encoded into json string inside myWebApi or should I encode it into json and pass in a string.
Or in otherwords
String postSomeData( String jsonData){
web code here..
}
or
ResponsePojo postSomeData( PostData myData){
...
myMapper.MapFrom(myData); //converts pojo to json
...
webcode
}
At some point there will be images included in the data needed to be uploaded.
I would recommend using json for data transfer, it will make your services technology independent.
You can use flexjon to serialize java objects in a pretty direct way on the server side.
For images you will need to do post http POST anyway, this should be done separately from data submit since an error in a image upload should not result in data loss. Typically you'll associate the id of your data object in the uploaded image (or reversly), so you need to insert your object to db and wait for the response to insert the dependency id to your image.
