Timeout Mechanism

HTTP API

The timeout setting of the HTTP API is relatively flexible. The priority of the settings decreases in turn: Request object -> Client object -> Default value.

The default connection timeout is 5 seconds and the read timeout is 10 seconds.

The following code demonstrates how to customize the timeout setting.

Python

from webullsdkcore.client import ApiClient
from webullsdkmdata.request.get_instruments_request import GetInstrumentsRequest
# Set the connection timeout to 3 seconds and the read timeout to 6 seconds.
client = ApiClient(app_key="<your_app_key>", app_secret="<your_app_secret>", region_id="<region_id>", connect_timeout=3,
                   timeout=6)

request = GetInstrumentsRequest()
# Set the connection timeout of the request to 2 seconds and the read timeout to 4 seconds, only valid for the current request.
request.set_connect_timeout(2)
request.set_read_timeout(4)

Java

HttpApiConfig apiConfig = HttpApiConfig.builder()
        .appKey("<your_app_key>")
        .appSecret("<your_app_secret>")
        .regionId(Region.us.name())
        // Set the connection timeout to 3 seconds and the read timeout to 6 seconds.
        .runtimeOptions(new RuntimeOptions().connectTimeout(3, TimeUnit.SECONDS).readTimeout(6, TimeUnit.SECONDS))
        .build();
HttpApiClient client = new HttpApiClient(apiConfig);

HttpRequest request = new HttpRequest("/app/subscriptions/list", Versions.V1, HttpMethod.GET);
// Set the connection timeout of the request to 2 seconds and the read timeout to 4 seconds, only valid for the current request.
request.setRuntimeOptions(new RuntimeOptions().connectTimeout(2, TimeUnit.SECONDS).readTimeout(4, TimeUnit.SECONDS));

List<Account> accounts = client.request(request).responseType(new TypeToken<List<Account>>() {}.getType()).doAction();

Quote Subscription

Market subscription is a persistent connection based on MQTT v3.1.1. The default connection timeout is 5 seconds, and the read timeout is 60 seconds (the connection will be maintained through the heartbeat packet within 60 seconds).

Python

Currently, there is no method for customizing the timeout configuration.

Java

QuotesSubsClient client = QuotesSubsClient.builder()
        .appKey("<your_app_key>")
        .appSecret("<your_app_secret>")
        .regionId(Region.us.name())
        // Set the connection timeout to 10 seconds and the read timeout to 60 seconds.
        .connectTimeout(10000)
        .readTimeout(60000)
        .build()

Trade Events Subscription / Quotes API

The trading events subscription is based on the persistent connection of Server Streaming implemented by gRPC. Currently, there is no way to customize the timeout configuration.

Python

The timeout is managed by Python's gRPC libs by default.

Java

The timeout is managed by Java's gRPC libs by default.
