如何解决HTML网页中文显示乱码的方法 如何解决HTML网页中文显示乱码的方法 第一：定义网页显示编码。如果不定义网页编码，那么我们浏览网页的时候，IE会自动识别网页编码，这就有可能会导致中文显示乱码了。所以我们做网页的时候，都会用“”来定义网页编码。(我们常见的Unicode码是utf-8)<html> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <head>把文件保存成utf-8的编码，仿着上面的位置，在页面加上中间那行代码，如果还有乱码就把utf-8改成gbk第二：网页存储编码。大家经常会忽略这个问题。我就用建站常用工具Dreamweaver来说吧。我们用DW新建一张默认的编码保存的时候都会保存为两种编码uft8格式或gbk格式，这个可以在Dreamweaver->编辑->首选项->新建文档 进行设置。如果你设置了默认utf8格式，那么网页存储编码就是utf8，同时使用来什么网页显示编码也为utf8，如果不一致就会导致乱码。我这样说明，不知道是否说明了问题。也就是说，我们在遇到乱码问题的时候，是由于编码不一致导致的。这个是html网页的乱码情况的总结，我们举一反三，我们在使用php虚拟主机建站的时候遇到乱码问题的时候，我们也要通过三个因素来考虑解决问题。我总结的三个因素：网页显示编码、网页存储编码、数据库编码网站出现中文显示乱码的时候，请先从这三个方向去考虑解决问题，将事半功倍。

图片加速接口：缓存图片，加速访问，解决防盗链 图片加速接口：缓存图片，加速访问，解决防盗链 一、加速接口1. WordPress提供的图片加速https://i0.wp.com/{url} https://i1.wp.com/{url} https://i2.wp.com/{url} https://i3.wp.com/{url} 其中url部分是不带协议头的，即https://2. 百度加速https://image.baidu.com/search/down?url={url} url填完整url，注意该url需要是直链，重定向链接会失效。3. CdnJson提供https://cdn.cdnjson.com/{url} 其中url部分是不带协议头的，即https:// 注意该url需要是直链，重定向链接会失效。4. 搜狗图片https://img02.sogoucdn.com/v2/thumb/retype_exclude_gif/ext/auto/q/95/crop/xy/ai/t/0/?appid=122&url={url} url为完整url5. 广西龙讯http://collect34.longsunhd.com/source/plugin/yzs1013_pldr/getimg.php?url={url} url为完整链接进阶使用https://pic.2ge.org/cdn/?url={url} url填完整url整合接口，使用这个接口会随机挑选上述一个接口进行加速，达到负载均衡的效果。同时，也能防止其中有接口挂了，也能进行筛除。转载自： 勿埋我心
