java.net.SocketTimeoutException dans okhttp

Question

Ici, il faut tellement de temps pour obtenir des données de json. Une fois supprimé et à nouveau installé, il obtiendra json en 1 min et lorsque je clique à nouveau sur le bouton pour json cela prend tellement de temps et les données ne parviennent toujours pas dans listview

Voici mon code d'exception

voici un code json dans Java:

    if (isNetworkAvailable()) {

        String url = "ConstantValue.URL";

                .add(employeeId, value)

     } else {
         Toast.makeText(MainActivity.this, "Internet not available", Toast.LENGTH_LONG).show();

Autres codes:

private final OkHttpClient client = new OkHttpClient();


Call post(String url, RequestBody formBody, Callback callback) throws IOException {

    Request request = new Request.Builder()
            .url(url)
            .post(formBody)
            .build();

    client.setConnectTimeout(30, TimeUnit.SECONDS);
    client.setReadTimeout(30, TimeUnit.SECONDS);
    client.setWriteTimeout(30, TimeUnit.SECONDS);

    Call call = client.newCall(request);
    call.enqueue(callback);
    return call;
}

Answer 1

IOExceptiojava.net.SocketTimeoutException se produit à la condition suivante.

1. Le serveur est lent et le délai d'expiration par défaut est inférieur. il suffit donc de mettre une valeur de timeout selon vous.
2. Le serveur fonctionne correctement mais la valeur de délai d'attente est pour moins de temps. modifiez donc la valeur du délai d'expiration. comme l'extrait de code ci-dessous.

Client OkHttpClient = new OkHttpClient ();

client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(30, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);

Si vous utilisez okhttp3, vous devez le faire à l'aide du générateur.

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(30, TimeUnit.SECONDS); 
builder.readTimeout(30, TimeUnit.SECONDS); 
builder.writeTimeout(30, TimeUnit.SECONDS); 
client = builder.build();
