假设有一个客户端尝试在**查询参数**中发送一些**额外的**数据，它将会收到一个**错误**响应。

例如，如果客户端尝试发送一个值为 `plumbus` 的 `tool` 查询参数，如：

```http
https://example.com/items/?limit=10&tool=plumbus
```

他们将收到一个**错误**响应，告诉他们查询参数 `tool` 是不允许的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

      throws Exception {
    File fileA = newFile("file-a");
    File dir1 = newDir("dir-1");
    newFile("dir-1/file-b");
    newFile("dir-1/dir-2");

    assertThat(Iterables.limit(Files.fileTraverser().breadthFirst(rootDir), 3))
        .containsExactly(rootDir, fileA, dir1);
  }

  public void testFileTraverser_multipleDirectoryLayers_traversalReturnsAll() throws Exception {

```java
// Configure memory usage
crawler.crawlerContext.setMaxAccessCount(10000);     // Limit crawled URLs
crawler.crawlerContext.setMaxDepth(5);               // Limit crawl depth

// Use streaming for large files
container.singleton("fileTransformer", FileTransformer.class, transformer -> {
    transformer.setMaxContentSize(10 * 1024 * 1024); // 10MB limit
});
```

## Troubleshooting

### Common Issues

Por exemplo, se o cliente tentar enviar um parâmetro de consulta `tool` com o valor `plumbus`, como:

```http
https://example.com/items/?limit=10&tool=plumbus
```

Eles receberão um retorno de **erro** informando-os que o parâmentro de consulta `tool` não é permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

  }

  @CanIgnoreReturnValue

      Java8Compatibility.position(b, b.limit());
    } else {
      for (int remaining = b.remaining(); remaining > 0; remaining--) {
        putByte(b.get());
      }
    }
    return this;
  }

    long limit = Long.MAX_VALUE + ((a ^ b) >>> (Long.SIZE - 1));

      return limit;
    }
    long result = a * b;
    if (a == 0 || result / a == b) {
      return result;
    }
    return limit;
  }
