我在 Microsoft Docs 看到有一种方法可以通过设置 PartitionId 而不是 PartitionKey（使用 C#）将数据发送到我想要的分区。CreatePartitionSender(String) 创建一个可以将 EventData 直接发布到特定 EventHub 分区的 PartitionSender。但是，我在 Python 中找不到相同的内容。有什么可用的方法吗？

有两种方法可以将数据发送到 Azure 事件中心，即 HTTP REST API 和 AMQP 1.0 协议。
对于使用 HTTP REST API 或Azure EventHub Python 客户端库，只有partitionId参数支持向 Event Hub 中的指定分区发送新事件，如下两个。
REST API
Send partition event需要partitionIdendpoint中的参数https://{servicebusNamespace}.servicebus.windows.net/{eventHubPath}/partitions/{partitionId}/messages，它是唯一一个支持发送分区特性的REST API。的源代码注释
Sender.py解释partition参数如下。:param partition: The specific partition ID to send to. Default is None, in which case the service will assign to all partitions using round-robin.:type partition: str
所以实际上，您不能使用partitionKeyvalue 将事件发送到指定的 EventHub 分区，除非在 Python 中使用 AMQP 1.0。使用AMQP 1.0，请查看官方文档AMQP 1.0 in Azure Service Bus and Event Hubs protocol guide并partition-key在页面上搜索，结果如下。

我不太确定，但使用 python ，这是打开连接的方法
def open(self):
"""
Open the Sender using the supplied conneciton.
If the handler has previously been redirected, the redirect
context will be used to create a new handler before opening it.
:param connection: The underlying client shared connection.
:type: connection: ~uamqp.connection.Connection
"""
self.running = True
if self.redirected:
self.target = self.redirected.address
self._handler = SendClient(
self.target,
auth=self.client.get_auth(),
debug=self.client.debug,
msg_timeout=self.timeout,
error_policy=self.retry_policy,
keep_alive_interval=self.keep_alive,
client_name=self.name,
properties=self.client.create_properties())
self._handler.open()
while not self._handler.client_ready():
time.sleep(0.05)
这是初始化
def __init__(self, client, target, partition=None, send_timeout=60, keep_alive=None, auto_reconnect=True):
"""
Instantiate an EventHub event Sender handler.
:param client: The parent EventHubClient.
:type client: ~azure.eventhub.client.EventHubClient.
:param target: The URI of the EventHub to send to.
:type target: str
:param partition: The specific partition ID to send to. Default is None, in which case the service
will assign to all partitions using round-robin.
:type partition: str
:param send_timeout: The timeout in seconds for an individual event to be sent from the time that it is
queued. Default value is 60 seconds. If set to 0, there will be no timeout.
:type send_timeout: int
:param keep_alive: The time interval in seconds between pinging the connection to keep it alive during
periods of inactivity. The default value is None, i.e. no keep alive pings.
:type keep_alive: int
:param auto_reconnect: Whether to automatically reconnect the sender if a retryable error occurs.
Default value is `True`.
:type auto_reconnect: bool
"""
self.running = False
self.client = client
self.target = target
self.partition = partition
self.timeout = send_timeout
self.redirected = None
self.error = None
self.keep_alive = keep_alive
self.auto_reconnect = auto_reconnect
self.retry_policy = errors.ErrorPolicy(max_retries=3, on_error=_error_handler)
self.reconnect_backoff = 1
self.name = "EHSender-{}".format(uuid.uuid4())
if partition:
self.target += "/Partitions/" + partition
self.name += "-partition{}".format(partition)
self._handler = SendClient(
self.target,
auth=self.client.get_auth(),
debug=self.client.debug,
msg_timeout=self.timeout,
error_policy=self.retry_policy,
keep_alive_interval=self.keep_alive,
client_name=self.name,
properties=self.client.create_properties())
self._outcome = None
self._condition = None
我相信，下面的函数行只会创建一个分区发送者
if partition:
self.target += "/Partitions/" + partition
self.name += "-partition{}".format(partition)
