* `read(size)`：讀取檔案的 `size` (`int`) 個位元組/字元。
* `seek(offset)`：移動到檔案中的位元組位置 `offset` (`int`)。
    * 例如，`await myfile.seek(0)` 會移到檔案開頭。
    * 當你已經執行過 `await myfile.read()`，之後需要再次讀取內容時特別有用。
* `close()`：關閉檔案。

由於這些都是 `async` 方法，你需要以 await 呼叫它們。

例如，在 `async` 的路徑操作函式中可這樣讀取內容：

```Python
contents = await myfile.read()
```

若是在一般的 `def` 路徑操作函式中，你可以直接存取 `UploadFile.file`，例如：

```Python

	// Object operations.

	// GetObjectNInfo returns a GetObjectReader that satisfies the
	// ReadCloser interface. The Close method runs any cleanup
	// functions, so it must always be called after reading till EOF
	//
	// IMPORTANTLY, when implementations return err != nil, this
	// function MUST NOT return a non-nil ReadCloser.

                if (offerBasic) {
                    response.addHeader("WWW-Authenticate", "Basic realm=\"" + this.realm + "\"");
                }
                response.setHeader("Connection", "close");
                response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
                response.flushBuffer();
                return;
            }
            final HttpSession ssn = request.getSession();

	findClosestCommands := func(command string) []string {
		var closestCommands []string
		closestCommands = append(closestCommands, commandsTree.PrefixMatch(command)...)

		sort.Strings(closestCommands)
		// Suggest other close commands - allow missed, wrongly added and
		// even transposed characters
		for _, value := range commandsTree.Walk(commandsTree.Root()) {
			if sort.SearchStrings(closestCommands, value) < len(closestCommands) {
				continue

		return "", gcsToObjectError(err, gcs.Bucket, key)
	}

	if _, err := xioutil.Copy(w, data); err != nil {
		return "", gcsToObjectError(err, gcs.Bucket, key)
	}

	return "", w.Close()
}

// FIXME: add support for remote version ID in GCS remote tier and remove this.
// Currently it's a no-op.

      val requestBodyOut = requestBody.takeSink()
      assertFailsWith<IOException> {
        SlowRequestBody.writeTo(requestBodyOut)
      }
      assertFailsWith<IOException> {
        requestBodyOut.close()
      }
    }

    // Confirm that the connection pool was not corrupted by making another call.
    makeSimpleCall()
  }

### Resource Cleanup Pattern

Always use try-with-resources for `ResponseData` - temp files are auto-deleted on close.

## Log Message Guidelines

- Format parameters as `key=value` (e.g., `sessionId={}`, `url={}`)
- Prefix with `[name]` when context identification is needed
- Use full words, not abbreviations

}

@Before
public void before() {
    runner.admin().indices().prepareDelete("_all").execute().actionGet();
}

@AfterClass
public static void afterClass() {
    runner.close();
    runner.clean();
}
```

### Testing Best Practices

- Minimize `Thread.sleep()` - use only when absolutely necessary
- For timestamp tests: use minimal delays (50-100ms)
