Logging Interceptor
===================

An [OkHttp interceptor][interceptors] which logs HTTP request and response data.

```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();
```

You can change the log level at any time by calling `setLevel()`.

            // get a content
            final HttpResponse response = executeHttpClient(httpGet);
            httpEntity = response.getEntity();

            final int httpStatusCode = response.getStatusLine().getStatusCode();
            if (httpStatusCode == 200) {

                // check file size
                final Header contentLengthHeader = response.getFirstHeader("Content-Length");

Wenn ein Client versucht, einige **zusätzliche Header** zu senden, erhält er eine **Error-<abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>**.

Zum Beispiel, wenn der Client versucht, einen `tool`-Header mit einem Wert von `plumbus` zu senden, erhält er eine **Error-Response**, die ihm mitteilt, dass der Header-Parameter `tool` nicht erlaubt ist:

```json
{
    "detail": [
        {

            } else {
                final SmbComOpenAndXResponse response = new SmbComOpenAndXResponse(config);
                h.send(new SmbComOpenAndX(config, uncPath, access, sharing, flags, attrs, null), response);
                this.fileLocator.updateType(response.getFileType());
                info = response;
                fileSize = response.getDataSize();

      @Override public void onFailure(Call call, IOException e) {
      }

      @Override public void onResponse(Call call, Response response) throws IOException {
        try (ResponseBody body = response.body()) {
          // Consume and discard the response body.
          body.source().readByteString();
        }
      }
    });
