## Installation Steps
|

### Preparation
|
||||
### Pre-installation preparation
|
||||
|
||||
1. Install Python. The recent taospy package requires Python 3.6.2+. The earlier versions of taospy require Python 3.7+. The taos-ws-py package requires Python 3.7+. If Python is not available on your system, refer to the [Python BeginnersGuide](https://wiki.python.org/moin/BeginnersGuide/Download) to install it.
|
||||
2. Install [pip](https://pypi.org/project/pip/). In most cases, the Python installer comes with the pip utility. If not, please refer to [pip documentation](https://pip.pypa.io/en/stable/installation/) to install it.

The `consumer` in the connector contains the subscription api.
|
||||
|
||||
##### Create Consumer
|
||||
|
||||
The syntax for creating a consumer is `consumer = Consumer(configs)`. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/).
|
||||
|
||||
```python
|
||||
from taos.tmq import Consumer
|
||||
|
||||
consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
|
||||
```
|
||||
|
||||
##### Subscribe topics
|
||||
|
||||
The `subscribe` function is used to subscribe to a list of topics.
|
||||
|
||||
```python
|
||||
consumer.subscribe(['topic1', 'topic2'])
|
||||
```
|
||||
|
||||
##### Consume
|
||||
|
||||
The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.
|
||||
|
||||
```python
|
||||
while True:
|
||||
res = consumer.poll(1)
|
||||
if not res:
|
||||
continue
|
||||
err = res.error()
|
||||
if err is not None:
|
||||
raise err
|
||||
val = res.value()
|
||||
|
||||
for block in val:
|
||||
print(block.fetchall())
|
||||
```
|
||||
|
||||
##### assignment
|
||||
|
||||
The `assignment` function is used to get the assignment of the topic.
|
||||
|
||||
```python
|
||||
assignments = consumer.assignment()
|
||||
```
|
||||
|
||||
##### Seek
|
||||
|
||||
The `seek` function is used to reset the assignment of the topic.
|
||||
|
||||
```python
|
||||
tp = TopicPartition(topic='topic1', partition=0, offset=0)
|
||||
consumer.seek(tp)
|
||||
```
|
||||
|
||||
##### After consuming data
|
||||
|
||||
You should unsubscribe to the topics and close the consumer after consuming.
|
||||
|
||||
```python
|
||||
consumer.unsubscribe()
|
||||
consumer.close()
|
||||
```

The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.

```python

### 数据订阅
|

<Tabs defaultValue="native">
|

<TabItem value="native" label="原生连接">
|
||||
|

`Consumer` 提供了 Python 连接器订阅 TMQ 数据的 API。
|
||||
|
||||
##### 创建 Consumer
|
||||
|
||||
创建 Consumer 语法为 `consumer = Consumer(configs)`，参数定义请参考 [数据订阅文档](../../develop/tmq/#%E5%88%9B%E5%BB%BA%E6%B6%88%E8%B4%B9%E8%80%85-consumer)。
|
||||
|
||||
```python
|
||||
from taos.tmq import Consumer
|
||||
|
||||
consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
|
||||
```
|
||||
|
||||
##### 订阅 topics
|
||||
|
||||
Consumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
|
||||
|
||||
```python
|
||||
consumer.subscribe(['topic1', 'topic2'])
|
||||
```
|
||||
|
||||
##### 消费数据
|
||||
|
||||
Consumer API 的 `poll` 方法用于消费数据，`poll` 方法接收一个 float 类型的超时时间，超时时间单位为秒（s），`poll` 方法在超时之前返回一条 Message 类型的数据或超时返回 `None`。消费者必须通过 Message 的 `error()` 方法校验返回数据的 error 信息。
|
||||
|
||||
```python
|
||||
while True:
|
||||
res = consumer.poll(1)
|
||||
if not res:
|
||||
continue
|
||||
err = res.error()
|
||||
if err is not None:
|
||||
raise err
|
||||
val = res.value()
|
||||
|
||||
for block in val:
|
||||
print(block.fetchall())
|
||||
```
|
||||
|
||||
##### 获取消费进度
|
||||
|
||||
Consumer API 的 `assignment` 方法用于获取 Consumer 订阅的所有 topic 的消费进度，返回结果类型为 TopicPartition 列表。
|
||||
|
||||
```python
|
||||
assignments = consumer.assignment()
|
||||
```
|
||||
|
||||
##### 指定订阅 Offset
|
||||
|
||||
Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置，方法参数类型为 TopicPartition。
|
||||
|
||||
```python
|
||||
tp = TopicPartition(topic='topic1', partition=0, offset=0)
|
||||
consumer.seek(tp)
|
||||
```
|
||||
|
||||
##### 关闭订阅
|
||||
|
||||
消费结束后，应当取消订阅，并关闭 Consumer。
|
||||
|
||||
```python
|
||||
consumer.unsubscribe()
|
||||
consumer.close()
|
||||
```
|
||||

除了原生的连接方式，Python 连接器还支持通过 websocket 订阅 TMQ 数据，使用 websocket 方式订阅 TMQ 数据需要安装 `taos-ws-py`。
|
||||
|
||||
taosws `Consumer` API 提供了基于 Websocket 订阅 TMQ 数据的 API。
|
||||
|
||||
##### 创建 Consumer
|
||||
|
||||
创建 Consumer 语法为 `consumer = Consumer(conf=configs)`，使用时需要指定 `td.connect.websocket.scheme` 参数值为 "ws"，参数定义请参考 [数据订阅文档](../../develop/tmq/#%E5%88%9B%E5%BB%BA%E6%B6%88%E8%B4%B9%E8%80%85-consumer)。
|
||||
|
||||
```python
|
||||
import taosws
|
||||
|
||||
consumer = taosws.(conf={"group.id": "local", "td.connect.websocket.scheme": "ws"})
|
||||
```
|
||||
|
||||
##### 订阅 topics
|
||||
|
||||
Consumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
|
||||
|
||||
```python
|
||||
consumer.subscribe(['topic1', 'topic2'])

|
||||
if not res:

##### 重置消费进度
|
||||
|
||||
Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置。
|
||||
|
||||
```python
|
||||
consumer.seek(topic='topic1', partition=0, offset=0)
|
||||
```
|
||||
|
||||
##### 结束消费
|
||||
|
||||
消费结束后，应当取消订阅，并关闭 Consumer。
|
||||
|
||||
```python

### 数据订阅
|
||||
|
||||
连接器支持数据订阅功能，数据订阅功能请参考 [数据订阅文档](../../develop/tmq/)。
|
||||
|
||||
#### 创建 Topic
|
||||
|
||||
创建 Topic 相关请参考 [数据订阅文档](../../develop/tmq/#创建-topic)。
|
||||
|
||||
#### 创建 Consumer
|
||||
|
||||
<Tabs defaultValue="native">
|
||||
|
||||
<TabItem value="native" label="原生连接">
|
||||
|
||||
`Consumer` 提供了 Python 连接器订阅 TMQ 数据的 API。创建 Consumer 语法为 `consumer = Consumer(configs)`，参数定义请参考 [数据订阅文档](../../develop/tmq/#创建消费者-consumer)。
|
||||
|
||||
```python
|
||||
from taos.tmq import Consumer
|
||||
|
||||
consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
|

```
|
||||
</TabItem>
|
||||
|
||||
<TabItem value="websocket" label="WebSocket 连接">
|
||||
|
||||
除了原生的连接方式，Python 连接器还支持通过 websocket 订阅 TMQ 数据，使用 websocket 方式订阅 TMQ 数据需要安装 `taos-ws-py`。
|
||||
|
||||
taosws `Consumer` API 提供了基于 Websocket 订阅 TMQ 数据的 API。创建 Consumer 语法为 `consumer = Consumer(conf=configs)`，使用时需要指定 `td.connect.websocket.scheme` 参数值为 "ws"，参数定义请参考 [数据订阅文档](../../develop/tmq/#%E5%88%9B%E5%BB%BA%E6%B6%88%E8%B4%B9%E8%80%85-consumer)。
|
||||
|
||||
```python
|
||||
import taosws
|
||||
|
||||
consumer = taosws.(conf={"group.id": "local", "td.connect.websocket.scheme": "ws"})
|
