Question

关于python中Service Bus订阅的相关性过滤器的文档不多。所有示例都涉及SQL过滤器。我试图应用与那里看到的相同的逻辑，但无济于事。

我有一个简单的测试用例，其中我要创建两个订阅，每个订阅都有一个关联过滤器。一个过滤器根据相关性id =高过滤，另一个过滤器对低过滤。

new = []
for L in range(0, len(stuff)+1):
    for subset in itertools.combinations(stuff, L):
        if sum(subset) == 10170090:
            new.append(subset)

new = list(map(list, new))

for i in new:
    lst = iter(list(zip(stuff, words)))
    a = next(lst)
    for idx, item in enumerate(i):
        while True:
            if item == a[0] and a[1] == 'RFQ_DELETED':
                i[idx] = a[1]
                break
            elif item == a[0]:
                i[idx] = a[1]
                a = next(lst)
                break
            else:
                a = next(lst)

print(new)

[['AGGGG', 'AUDIT + PARK', 'AUDIT + PENDING', 'PENDING'], 
 ['AGGGG', 'AUDIT + PENDING', 'LIVE', 'PENDING'], 
 ['AGGGG', 'AUDIT + PENDING', 'PENDING', 'RFQ_DELETED'], 
 ['AGGGG', 'AUDIT + PARK', 'AUDIT + PENDING', 'AUDIT + QUOTE_CREATED,AUDIT + QUOTE_DELETED', 'REJECT'], 
 ['AGGGG', 'AUDIT + PENDING', 'AUDIT + QUOTE_CREATED,AUDIT + QUOTE_DELETED', 'LIVE', 'REJECT'],  
 ... 
 ['AGGGG', 'AUDIT + PENDING', 'AUDIT + QUOTE_CREATED,AUDIT + QUOTE_DELETED', 'AUDIT + QUOTE_REJECTED', 'LIVE', 'QUOTE_CREATED', 'RFQ_DELETED'], 
 ['AGGGG', 'AUDIT + PENDING', 'AUDIT + QUOTE_REJECTED', 'AUDIT + QUOTE_UPDATED', 'LIVE', 'REJECT', 'RFQ_DELETED'], 
 ['AGGGG', 'AUDIT + PENDING', 'AUDIT + QUOTE_REJECTED', 'LIVE', 'QUOTE_CREATED', 'REJECT', 'RFQ_DELETED'], 
 ['AGGGG', 'AUDIT + PENDING', 'AUDIT + QUOTE_REJECTED', 'LIVE', 'QUOTE_CREATED', 'REJECT', 'RFQ_DELETED']
]

我正在通过发送correlation_id设置为低的消息来测试这些过滤器。

    _create_subscription(bus_service, 'filter-test-topic', 'highsub')

    high_rule = Rule()
    high_rule.filter_type = 'CorrelationFilter'
    high_rule.correlation_filter = CorrelationFilter(correlation_id='high')

    bus_service.create_rule('filter-test-topic', 'highsub', 'HighMessageFilter', high_rule)
    bus_service.delete_rule('filter-test-topic', 'highsub', DEFAULT_RULE_NAME)

    _create_subscription(bus_service, 'filter-test-topic', 'lowsub')

    low_rule = Rule()
    low_rule.filter_type = 'CorrelationFilter'
    low_rule.filter_expression = CorrelationFilter(correlation_id='low')

    bus_service.create_rule('filter-test-topic', 'lowsub', 'LowMessageFilter', low_rule)
    bus_service.delete_rule('filter-test-topic', 'lowsub', DEFAULT_RULE_NAME)

我希望在“ lowsub”中看到5条消息，在“ highsub”中看到0条消息。但是，当我检查azure门户时，两个订阅都有0条消息。

我可以正确创建过滤器吗？我是否在消息中正确设置了correlation_id？我不确定我在做什么错。
