* Fügen Sie es als „Middleware“ zu Ihrer **FastAPI**-Anwendung hinzu.

Sie können auch angeben, ob Ihr Backend erlaubt:

* Anmeldeinformationen (Autorisierungsheader, Cookies, usw.).
* Bestimmte HTTP-Methoden (`POST`, `PUT`) oder alle mit der Wildcard `"*"`.
* Bestimmte HTTP-Header oder alle mit der Wildcard `"*"`.

## Architecture

### Core Components

- **`Curl`**: Static entry point providing factory methods for all HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, CONNECT, TRACE). Also defines the `Method` enum and `tmpDir` constant.

        // Test various positions
        int[] positions = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 15, 16 };
        for (int pos : positions) {
            int padding = (int) pad8Method.invoke(req, pos);

            // Verify padding makes position 8-byte aligned
            assertEquals(0, (pos + padding) % 8);
        }
    }

    @Test
    @DisplayName("Should write bytes at different buffer offsets")

    server.enqueue(MockResponse())
    server.start()
    val call =
      client.newCall(
        Request
          .Builder()
          .url(server.url("/"))
          .post(
            object : RequestBody() {
              override fun contentType() = null

              override fun writeTo(sink: BufferedSink) {
                for (i in 0..9) {
                  sink.writeByte(0)

* Bunu **FastAPI** uygulamanıza bir "middleware" olarak ekleyin.

Ayrıca backend’in şunlara izin verip vermediğini de belirtebilirsiniz:

* Credentials (Authorization header’ları, Cookie’ler, vb).
* Belirli HTTP method’ları (`POST`, `PUT`) veya wildcard `"*"` ile hepsini.
* Belirli HTTP header’ları veya wildcard `"*"` ile hepsini.
