# DropFields 类
<a name="aws-glue-api-crawler-pyspark-transforms-DropFields"></a>

删除 `DynamicFrame` 中的字段。

## 示例
<a name="pyspark-DropFields-examples"></a>

我们建议您使用 [`DynamicFrame.drop_fields()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-drop_fields) 方法从 `DynamicFrame` 中删除字段。要查看代码示例，请参阅 [示例：使用 drop\_fields 从 `DynamicFrame` 中删除字段](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-drop_fields-example)。

## \_\_call\_\_(frame, paths, transformation\_ctx = "", info = "", stageThreshold = 0, totalThreshold = 0)
<a name="aws-glue-api-crawler-pyspark-transforms-DropFields-__call__"></a>

删除 `DynamicFrame` 中的字节。
+ `frame` – 要在其中删除节点的 `DynamicFrame`（必需）。
+ `paths` – 要删除的节点的完整路径的列表 (必需)。
+ `transformation_ctx` – 用于标识状态信息的唯一字符串 (可选)。
+ `info` – 与转换中的错误关联的字符串 (可选)。
+ `stageThreshold` – 在转换出错之前可能在其中发生的最大错误数（可选）。默认值为 0。
+ `totalThreshold` – 在处理出错之前可能全面发生的最大错误数（可选）。默认值为 0。

返回不包含指定字段的新 `DynamicFrame`。
