特色
目前共三个相册:原神、yuri、kano,大部分图片收集自P站,人肉精选。图片比例约为16:9,分辨率2160P。原始图片通过PhotoShop使用“保留细节2.0”超分(或超采样缩放)至4K,后在PS中转码为webp格式,在质量与图片体积中平衡取舍。
7个自定义参数:
- output:cdn,使用CDN输出;pass,使用本机二进制输出
- cdn_choose:选择哪个CDN
- default_album:未指定相册或URL参数错误时默认输出的相册
- mobile_default_album:移动端请求时,若未指定相册或参数错误,默认输出的相册
- diff_domain:是否使用域名分流策略,开启后
referer_list
里的域名会使用cdn_choose
里的CDN,其它域名使用CloudFlare CDN - referer_list:域名分流列表
- cdn_list:可用的cdn列表,随心切换
请确保数组里的文件名和磁盘(或CDN)中的文件对得上,文件夹结构一致。需要修改的话,两者都要修改,否则404。
可以配置多个CDN地址,如CDN异常可在API中快速进行切换,前端无需调整。
当output
选择为pass
时,不使用CDN时不做302跳转,直接使用本机进行二进制输出,对服务器性能有略微的影响,服务器带宽小不建议使用直出的方式。
API代码未作任何输入校验和错误处理。
图包下载:library.zip
图片文件名即为PIXIV ID,图片均收集自网络,非商业化使用,如有侵权,请联系我删除!
如何使用
基本使用
API URL:https://api-images.kanochan.net/api.php
https://api-images.kanochan.net/api.php
将图片URL替换成上面的API URL即可,同一页面多次引用在末尾加上随机字符以做区分,如:
https://api-images.kanochan.net/api.php?250
进阶使用
API URL:https://api-images.kanochan.net/api.php?album=yuri&
https://api-images.kanochan.net/api.php?album=yuri&
album
用于指定输出相册,格式:album=相册名称
,未指定则以default_album
中的相册进行输出。
可选的相册:
- 原神:https://api-images.kanochan.net/api.php?album=Genshin-Impact&
- Yuri:https://api-images.kanochan.net/api.php?album=yuri&
- kano(竖向):https://api-images.kanochan.net/api.php?album=kano-verticalt&
- kano(横向):https://api-images.kanochan.net/api.php?album=kano-horizontal&
图片一览
- 原神Genshin Impact(慎入!可能需要500MB流量)
- Yuri
只是觉得女孩子们之间真是好啊(慎入!可能需要500MB流量) - kano
可用的CDN列表
唔,这是ilulu赞助的,需要refferer加白名单。
这是萝莉控ilolicon赞助的,可以托管5GB的图片哦,快联系TA吧
使用Cloudflare,速度随缘。
- .......正在等待更多大佬赞助CDN(划掉)
一些帮助
这个小函数可以帮你把文件夹里的图片输出为数组,本来想集成进API里,算了算了。
<?php
/**
* 获取图库数据
* @param $dir 要查找的文件路径
* @param $dirArray 存储文件名的数组
* @param $albumName 相册名称,以目录来命名
*/
function getImgList($dir, &$dirArray)
{
// 读取当前目录下的所有文件和目录(不包含子目录下文件)
$filesList = scandir($dir);
if (is_array($filesList)) {
foreach ($filesList as $val) {
// 跳过. 和 ..
if ($val == '.' || $val == '..')
continue;
// 判断是否是目录
if (is_dir($dir . '/' . $val)) {
getImgList($dir . '/' . $val, $dirArray); //遇到目录递归继续往下寻找
} else {
$albumName = end(explode('/',$dir)); //获取图片文件所在的目录名称
$dirArray[$albumName]['imgDir'] = $dir; //记录图片相对路径
$dirArray[$albumName]['imgLib'][] = $val; //记录图片文件名
}
}
