The disadvantage of using this crawler is very low efficiency, fool-like crawler, can not be executed in parallel, but its advantage is the analysis of the DOM tree structure analysis of the Web page source and information crawling, and it can be crawled through the browser of the intermediate process demonstration and verification code input.

1, the title requirements: In addition to integers, but also to support the true score of the arithmetic.2, design ideas: (1) The production of the operand:A. Define a random function with a macro definition.B. Random random functions are used to generate random numbers and define the range of values for random numbers.(2) Operator problem Resolution:A. Invoking random functions to generate 0~3 four random numbersB. Quote Swatch, case structure, randomly select operation symbol: 0: Add 1: minus
remainder, then add a condition, if the operator is division,a%b=0), whether to support fractions (separately add output function, judge the output of the score). It should be judged whether the topic repeats. With a for loop control, if the first number repeats, then check the second number, if the second number is also repeated, then check the operation symbol, if all repeat, then delete this question, another problem. If one of these three controls is not satisfied, then break exits. Resul
RabbitMQ (Fri)--Topics
' Topic Exchange ' in ' RABBITMQ ' matches the routing key with a pattern, which is similar to a regular match to receive the information you like.
Topic ExchangeIf you want to use ' topic ' mode, then you can set ' Routing_key '. Instead, the value needs to be set according to certain requirements.' Routing_key ' in topic mode, you should select a group of words that have a specific attribute as the value.

Because of the "*" (star)and "#" (hash), Topic Exchange is very powerful and can be converted to other Exchange:
If Binding_key is "#"-It will receive all the message, no matter what Routing_key is, it is like Fanout exchange.
If "*" (Star) and "#" (hash) is not used, then topic Exchange becomes direct exchange.
