php调用阿里云的颜色识别SDK报错 Warning: array_slice() expects parameter 1 to be array, null given in

问题遇到的现象和发生背景

php调用阿里云的颜色识别SDK总是报错
调用的内容可以正常输出，但是会有一句报错：Warning: array_slice() expects parameter 1 to be array, null given in

总是报错“Warning: array_slice() expects parameter 1 to be array, null given in ”

运行结果及报错内容

报错的问题应该是最后一行：Sample::main(array_slice($argv, 1));

我想要达到的结果

帮忙看看哪里的问题

accessKeyId你得key值这里调用成功没？ 现在报错是因为你得key，打印一下你得key对不对
