* canceled. For example, happy-path events like [requestHeadersStart] and [requestHeadersEnd] may
   * occur after a call is canceled. Typically cancellation takes effect when an expensive I/O
   * operation is required.

   * This is invoked at most once, even if [Call.cancel] is invoked multiple times. It may be
   * invoked at any point in a call's life, including before [callStart] and after [callEnd].

cUrl-like Java Client
[![Java CI with Maven](https://github.com/codelibs/curl4j/actions/workflows/maven.yml/badge.svg)](https://github.com/codelibs/curl4j/actions/workflows/maven.yml)
=====================

curl4j is a simple cUrl-like Java client.

## Version

[Versions in Maven Repository](https://repo1.maven.org/maven2/org/codelibs/curl4j/)

## Using Maven

Put the following block into pom.xml if using Maven:

    <dependency>

  public TestSuite createTestSuite() {
    checkCanCreate();

    logger.fine(" Testing: " + name);
    logger.fine("Features: " + formatFeatureSet(features));

    addImpliedFeatures(features);

    logger.fine("Expanded: " + formatFeatureSet(features));

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Laden Sie Traefik herunter</a>, es ist eine einzelne Binärdatei, Sie können die komprimierte Datei extrahieren und sie direkt vom Terminal aus ausführen.

Dann erstellen Sie eine Datei `traefik.toml` mit:

```TOML hl_lines="3"
[entryPoints]

Sie können `json_schema_extra` setzen, mit einem `dict`, das alle zusätzlichen Daten enthält, die im generierten JSON-Schema angezeigt werden sollen, einschließlich `examples`.

Webhooks sind in OpenAPI 3.1.0 und höher verfügbar und werden von FastAPI `0.99.0` und höher unterstützt.

## Eine Anwendung mit Webhooks

Wenn Sie eine **FastAPI**-Anwendung erstellen, gibt es ein `webhooks`-Attribut, mit dem Sie *Webhooks* definieren können, genauso wie Sie *Pfadoperationen* definieren würden, zum Beispiel mit `@app.webhooks.post()`.

  fun connectionPreface() {
    this.withLock {
      if (closed) throw IOException("closed")
      if (!client) return // Nothing to write; servers don't send connection headers!
      if (logger.isLoggable(FINE)) {
        logger.fine(format(">> CONNECTION ${CONNECTION_PREFACE.hex()}"))
      }
      sink.write(CONNECTION_PREFACE)
      sink.flush()
    }
  }

  /** Applies `peerSettings` and then sends a settings ACK. */

        assertEquals(UserAgentType.IE, userAgentHelper.getUserAgentType());
    }

    public void test_getUserAgentType_Chrome() {
        getMockRequest().addHeader("user-agent",
                "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.52 Safari/537.36");

They tend to require more complex configurations, a message/job queue manager, like RabbitMQ or Redis, but they allow you to run background tasks in multiple processes, and especially, in multiple servers.

#### Using `StreamingResponse` with file-like objects

If you have a file-like object (e.g. the object returned by `open()`), you can create a generator function to iterate over that file-like object.

That way, you don't have to read it all first in memory, and you can pass that generator function to the `StreamingResponse`, and return it.
