Let's understand such a problem first, If our front-end development needs are the needs given to us by the demand side, It is possible that a front-end developer will deal with multiple demanders, Therefore, it will keep in touch with multiple demand parties. Then in the program it means keeping references to multiple objects, The larger the program, There will be more and more objects, The relationship between them will become more and more complicated. Now if there is an intermediary (if it is our supervisor) to meet the needs of multiple demanders, Then the demander only needs to give all the requirements to our supervisor, who will assign tasks to us according to our workload in turn. In this way, our front-end development does not need to contact with multiple business parties, we only need to contact our supervisor (i.e. Intermediary), which weakens the coupling between objects.Proxy is a noun and Delegate is a verb. Secondly, proxy shows that several objects implement a common interface, while delegate only shows that one object references another object and does not involve an interface.　　天赐的干爹高志添（夏雨 饰）为了儿子高青（王喜 饰）与孙女也是处处迁就照顾，但高青只为了培养女儿，甚至无暇顾及妻子的感受，最后离婚收场。高青处于人生低潮的时候，幸得女儿老师罗四喜（杨怡 饰）的大力支持，到后来他才发现四喜对他的情感所在，无奈他心中最重要的还是自己的女儿《女马帮》是姜运民、宗庆平执导的电视剧。讲述的是上世纪30年代发生在云南的一个女锅头的奋斗故事，将彩云之南的秀丽风景和博大精深的云南文化呈现在观众面前。斯普纳和凯文开始了对抗机器人的行动，一场制造者和被制造者之间的战争拉开序幕。军士们都用吃奶的劲儿喊了出来。If a malicious request has characteristics, it is very simple to deal with: just intercept it directly.
