Http/Header 里private static function isValidKeyName($str)函数报错问题

[doghap]

问题报错原因是count()函数只对Countable或数组有效，而字符串则需要用strlen()函数去求长度

php-sdk/src/Qiniu/Http/Header.php

Line 265 in dd4b3d3

private static function isValidKeyName($str)

[doghap]

具体错误为：count(): Parameter must be an array or an object that implements Countable
