So when calling createPublication(), you have two methods with the same name:
One is createPublication(Publication)
The other is createPublication(Publication, String) <-- -- You want to use this one because the second parameter String is filled with the device id on which you want to attach the publication

I'm using createPublication(Publication, String) but I have an error saying "cannot resolve method", did I fill it wrong?

    Publication publicationConf2 = new Publication("conference2", 20d, 2000d);
    matchMore.createPublication(publicationConf2, "df8dbde6-326c-49f1-82a1-a5cbffeb1290");

@wenjdu

matchMore.createPublication(publication, "deviceIdExample",
                    createdPublication -> {
                return INSTANCE; },
                    e -> {
                return INSTANCE; }
                    );

Did you add the asynchronous callback ?

@GiacL

he will com back in a moment

it works, ty

GiacL

@GiacL

@wenjdu my test was wrong, it created once again with my device id and not the pinDeviceID

wenjdu

@wenjdu

Could you copy paste your code here please

With markdown if possible

GiacL

@GiacL

``` (shift+enter for line break)
var code = "formatted";
PinDevice pinDevice = new PinDevice("pinDeviceTransport", new MatchMoreLocation(32L,46.52214476,6.64595656) );
matchMore.createPinDevice(pinDevice, createdPinDevice ->{
Toast.makeText(getApplicationContext(), "pinDevice créé", Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(), "pinDeviceID = " + createdPinDevice.getId(), Toast.LENGTH_SHORT).show();
this.pinID = createdPinDevice.getId();
return Unit.INSTANCE;
}, e -> {
Toast.makeText(getApplicationContext(), "erreur creation pinDevice: " + e.getMessage(), Toast.LENGTH_SHORT).show();
Log.d("JavaExample", e.getMessage());
return Unit.INSTANCE;
});
Publication publicationConf = new Publication("conference", 3330d, 3330d);
matchMore.createPublication(publicationConf, pinID, createdPublication ->{
Toast.makeText(getApplicationContext(), "Publication créée", Toast.LENGTH_SHORT).show();
Log.d("TARTATIN", createdPublication.toString());
return Unit.INSTANCE; // return Unit.INSTANCE; is important (b/c kotlin vs java lambdas differ in implementation)
}, e -> {
Toast.makeText(getApplicationContext(), "erreur creation publication: " + e.getMessage(), Toast.LENGTH_SHORT).show();
Log.d("JavaExample", e.getMessage());
return Unit.INSTANCE;

});

```

sorry don't know how it's work markdown

wenjdu

@wenjdu

matchMore.createPublication(publicationConf, pinID, createdPublication ->{
Toast.makeText(getApplicationContext(), "Publication créée", Toast.LENGTH_SHORT).show();
Log.d("TARTATIN", createdPublication.toString());
return Unit.INSTANCE; // return Unit.INSTANCE; is important (b/c kotlin vs java lambdas differ in implementation)
}, e -> {
Toast.makeText(getApplicationContext(), "erreur creation publication: " + e.getMessage(), Toast.LENGTH_SHORT).show();
Log.d("JavaExample", e.getMessage());
return Unit.INSTANCE;

it should be working

what errors messages you get in the log ?

GiacL

@GiacL

got no error message

The publication is created, but it takes my deviceID and not the pinDeviceID

when i see the match

wenjdu

@wenjdu

Log.d("TARTATIN", createdPublication.toString());

then do you see something in the log debug ?

@wenjdu

deviceId=448af123-5b92-4b2b-b249-160b57434c2b is it the id of your pin ?

GiacL

@GiacL

no it's the id of my device

wenjdu

@wenjdu

matchMore.createPinDevice(pinDevice, createdPinDevice ->{
Toast.makeText(getApplicationContext(), "pinDevice créé", Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(), "pinDeviceID = " + createdPinDevice.getId(), Toast.LENGTH_SHORT).show();
this.pinID = createdPinDevice.getId();
return Unit.INSTANCE;
}, e -> {

Can you log the pin device id

and compare

it shouldn't be your main device id in the publication

@wenjdu

Can you matchmore.createPublication(yourPublication, "40bdeb11-b03a-4823-81bb-33b99e5cfbf2")

Try it like that and give me the log again

wenjdu

@wenjdu

ok see you are publishing on the right device id now

GiacL

@GiacL

yeah but i put the String directly, i can't put that in a variable?

wenjdu

@wenjdu

So I think the issue is related with the value you store inside of your variable this.pinID

GiacL

@GiacL

ok, thank you

wenjdu

@wenjdu

Yes you definately can but be careful with the callbacks

GiacL

@GiacL

thanks

wenjdu

@wenjdu

When there is asynchronous calls, you have to make sure that async call One is finished before async call Two is launched. Especially, when you need a value that is returned with async call One.

In your case, you have pinID which is supposed to be store at the end of the async call One, but if your async call Two is called before async call One is done. Then you will have pinID = null, which lead to the case where createPublication(publication, null) == you create a publication for your main device.

Bonjour, quel type d'infrastructure (en terme de serveur) utilisez-vous ?

Bonjour @arthfr, notre service fonctionne dans le Cloud (GCloud) et pour l'utiliser vous n'avez pas besoin d'infrastructure de votre côté. Nos sdks communiquent avec le backend directement. Est-ce que cela répond à votre question?

Hi, I'm trying to make a publication from a server in Java. If I understood correctly, I need to make a post request on your rest api using this url: https://api.matchmore.io/v5/devices/{deviceId}/publications

Then I need to replace the brackets of the deviceId by my deviceId. However, I still have the following question: how do I structure the header of the request? Do I only need the api key ? or should I put any username and password encrypted too?

For example taking this code:
´´´
HttpPost createConnectivity(String restUrl, String username, String password)
{
HttpPost post = new HttpPost(restUrl);
String auth=new StringBuffer(apiKey).toString();
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("UTF-8")));
String authHeader = "Basic " + new String(encodedAuth);
post.setHeader("AUTHORIZATION", authHeader);
post.setHeader("Content-Type", "application/json");
post.setHeader("Accept", "application/json");
post.setHeader("X-Stream" , "true");
return post;
}

´´´
Would it be the correct approach for the header?

Adam Smolarek

@adamsmo

there is no need for user and password
only apiKey

Hello, I'm trying to do the same as Arnaud, But I get a HandShake_Failure.
This is my code: Do I need to specify authentication somewhere?

....
public class Test {
public static void main(String[] args) throws IOException {
URL url = new URL("https://api.matchmore.io/v5/devices/{deviceId}/publications");
HttpsURLConnection httpCon = (HttpsURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("POST");
OutputStreamWriter out = new OutputStreamWriter(
httpCon.getOutputStream());
System.out.println(httpCon.getResponseCode());
System.out.println(httpCon.getResponseMessage());
out.close();
}
}

Łukasz Młynik

@lmlynik

@nico368 what is your device id?

nico368

@nico368

sorry

Łukasz Młynik

@lmlynik

also, yes, you need toto provide your appi key just like @Ohmere03

you just need to call setHeader("AUTHORIZATION", "<your api key>");
