```java
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
  Request request = new Request.Builder()
      .url(url)
      .build();

  try (Response response = client.newCall(request).execute()) {
    return response.body().string();

Post to a Server
----------------

This program posts data to a service. [Full source][post_example].

```java

import jcifs.internal.util.SMBUtil;

/**
 * SMB2 Echo response message.
 *
 * This response confirms that the server is still active
 * and the connection is working properly.
 *
 * @author mbechler
 */
public class Smb2EchoResponse extends ServerMessageBlock2Response {

    /**
     * Constructs an SMB2 echo response
     * @param config the client configuration
     */

Wenn Sie das ausführen und auf [http://localhost:8000/v1/](http://localhost:8000/v1/) gehen, sehen Sie die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> von Flask:

```txt
Hello, World from Flask!
```

Und wenn Sie auf [http://localhost:8000/v2](http://localhost:8000/v2) gehen, sehen Sie die Response von FastAPI:

```JSON
{
    "message": "Hello World"
}

    app = FastAPI()

    client = TestClient(app)

    @app.get("/test/")
    def call(test: Annotated[str, Depends(Dep())]):
        return {"test": test}

    response = client.get("/test")

İkili veriyi JSON içinde encode etmek yerine, yükleme için [Request Files](../tutorial/request-files.md) ve gönderim için [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) kullanıp kullanamayacağınıza önce bir bakın.

JSON sadece UTF-8 ile encode edilmiş string'ler içerebilir, dolayısıyla ham bytes içeremez.
