通过抓包得知, 楼主所请求的这个图片, 对方的服务器, 不按套路出牌, 不管客户端支持不支持gzip
解码,
而直接将内容使用gzip
压缩之后输出, 所以导致PHP
获取到的数据是经过压缩的,而你没有指定让它解压,
所以把它压缩后的数据当成图片来进行解析, 而这个数据当然不是图片了, 所以就得不到图片的信息了.
使用下面的代码即可:
<?php var_dump(getimagesize('compress.zlib://http://kids.file.putaocdn.com/file/4/ee/4eee9185e2fc60188b49bacdcc0c65ccfdecf8e8.jpg'));
先检查一下 file_get_contents('http://kids.file.putaocdn.com/file/4/ee/4eee9185e2fc60188b49bacdcc0c65ccfdecf8e8.jpg')
是否能成功。很可能是php设置不能获取远程图片,或者请求时对方屏蔽了php的请求。
如果文件可以成功获取,那把文件保存下来,再次使用getimagesize识别。
