音乐小说磁力下载器,go后端web版- 编程源码 -卓越飞翔博客

学习html/css/js/go基础知识所写,此源码是最后一个go版本,
由于go错误处理有问题,不仅语法太啰嗦,还影响代码链式调用,
以后打算主学js不再深入学习go了,后续源码只发nodejs版本,
js不仅语法灵活,还能前后端统一,无论js逆向还是油猴脚本开发,
都离不开js基础,py暂时不打算使用,等js熟练以后会再做考虑!

磁力由于版规所限,前段时间没打算发出去,
由于19号磁力站被封了,正好把源码发出去,
磁力功能暂不可用,仅供大家参考一下,
win成品压缩包未加密,go源码压缩包密码:52pj

html源码中用的免费临时图床，如果后续背景图片过期了，或者觉得背景图片加载缓慢，可以把html源码中的背景图地址替换为1.jpeg就行了，乱码字体库替换为1.woff，不用在地址前加http前缀，html的修改需要重新编译，win程序中已打包这几个外部文件，但图片地址忘改暂时没法修改了，感兴趣的自行修改重新编译一下，我就不重新编辑发帖了，对移动端也做了页面自适应，可以通过内网直接访问，win用户在cmd中用ipconfig就可以看到主机ip，ipv4地址一栏中以192.168开头的就是，手机浏览器输入就可以访问

代码中有个小bug,一开始没注意到,但不影响正常使用,在根据歌曲数/68进行分页计算时,错误的用整除后的结果取余,结果就是当歌曲数正好是68的倍数，总页数也会多加一页，虽然这种概率很小，也算是一个小问题,下面是需要修改的部分:
s1,_:=strconv.Atoi(r1.FindStringSubmatch(b)[1])
s2:=s1/68
if s2%68>0{s2++}
s3,_:=strconv.Atoi(r.Form[`v`][0])
if s3>s2{return}
s:=r2.FindAllStringSubmatch(b,-1)
io.WriteString(w,strconv.Itoa(s2)+`　`)

把上面这段代码替换为下面这段代码:
s1,_:=strconv.Atoi(r1.FindStringSubmatch(b)[1])
if s1%68>0{s1=s1/68+1}else{s1=s1/68}
s2,_:=strconv.Atoi(r.Form[`v`][0])
if s2>s1{return}
s:=r2.FindAllStringSubmatch(b,-1)
io.WriteString(w,strconv.Itoa(s1)+`　`)
