['bob', 'about', 'Zoo', 'Credit']

忽略字母大小写，进行名字排序[('adam', 92), ('bob', 75), ('cart', 66), ('Eisa', 88)]

按成绩从低到高排序：[('cart', 66), ('bob', 75), ('Eisa', 88), ('adam', 92)]

按成绩从高到低排序：[('adam', 92), ('Eisa', 88), ('bob', 75), ('cart', 66)]

忽略字母大小写，对req字典按key排序：[('channel', 'guanwang'), ('clientId', '5b3b4510e48cc6703a96102f19beec1b'), ('clientVer', '1.3.1'), ('loginPlatform', 'android'), ('loginToken', ''), ('sign', '4efb209fb3021e09f737f3dc4a6ddec4'), ('systemOs', 'vivo'), ('timeStamp', 1563434953)]
