# 获取数据游标
参见[初始化DIS客户端](https://support.huaweicloud.com/sdkreference-dis/dis_06_0043.html)的操作初始化一个DIS客户端实例。
配置参数如下：
```
partitionId="shardId-0000000000"  
streamname=”dis-test1“ #已存在的通道名
5种游标设置使用参考如下：
# startSeq与AT_SEQUENCE_NUMBER/AFTER_SEQUENCE_NUMBER搭配使用
r = cli.getCursor(streamname, partitionId, cursorType='AT_SEQUENCE_NUMBER', startSeq="0")
# r = cli.getCursor(streamname, partitionId, cursorType='AFTER_SEQUENCE_NUMBER', startSeq="0")
# timestamp与AT_TIMESTAMP搭配使用
# r = cli.getCursor(streamname, partitionId, cursorType='AT_TIMESTAMP',timestamp=1554694135190)
# r = cli.getCursor(streamname, partitionId, cursorType='TRIM_HORIZON')
# r = cli.getCursor(streamname, partitionId, cursorType='LATEST')
```
配置好以上参数，执行getCursor_sample.py文件调用getCursor_test方法，响应结果示例如下：
```
