If you closely look at the HTTP Request methods, for Peek Lock the request method is Post while for Receive and Delete it is Delete . 如果您仔细查看HTTP Request方法，则对于Peek Lock ，请求方法为Post而对于Receive and Delete ，请求方法为Delete 。

If you want to Peek Lock a message, you will need to use HTTP POST method. 如果要Peek Lock消息，则需要使用HTTP POST方法。

However, please keep in mind that Peek Lock method dequeues a message from the queue and it will remain invisible to other callers for certain duration. 但是，请记住， Peek Lock方法使消息从队列中出队，并且在某些持续时间内，其他调用者将看不见该消息。 Furthermore after a message has been dequeued a certain number of times, it will be dead lettered. 此外，在将消息出队一定次数后，该消息将被删除。

Unfortunately simple peeking at a message (ie fetching a message without dequeuing it) is not possible with REST API (HTTP Protocol). 不幸的是，使用REST API（HTTP协议）无法简单地窥视消息（即在不使消息出队的情况下获取消息）。 You will need to use AMQP protocol to do so. 您将需要使用AMQP协议。
