匹配location的过程其实可以理解成一个在众多选项中寻找最佳答案的过程。当然“”代表的就是正确答案而其它情况只是相对于正确答案的最佳选项。下面我们来看具体的匹配顺序 1.Nginx按照location配置顺序依次进行匹配 2.如果请求URI部分前缀或全部与location uri匹配先记录下来(如有匹配长度更长的则覆盖记录)继续向下匹配再看看是否还有最佳答案备胎最后再考虑你 3.如果与选项精确匹配则立刻停止匹配高富帅你就是我心目中的白马王子参考测试1 4.如果跟^~选项匹配成功还要继续完成所有匹配最长匹配策略直到找到与^~匹配长度最长的那个选项后再停止匹配如果实在找不到其它的就只能拿这个凑合了虽然都不帅但我要找最有钱的那位参考测试2 5.如果跟~或~*任意选项匹配成功则立刻停止好不容易遇到一个爆发户不拖泥带水立刻下手参考测试3、4 6.完成所有匹配。前面5步中每一步但凡匹配成功都会覆盖结果记录。如果匹配过程能进入第6步说明请求URI前缀与location uri匹配是最好的结果了最长匹配策略最终的结果记录也就是最佳答案在备胎中选择最佳备胎残忍现实。参考测试5 优先级 结合上面的匹配顺序和所有测试过程我们对各种匹配规则的作用优先级做个排序。 优先级排序匹配规则修饰符1精确匹配2指定字符串开头^~3正则匹配~、~*
