做p2p穿透所使用的协议为xtcp，搭建最少需要一台服务端两台客户端。优点：仅少量占用服务器带宽，占用的带宽可忽略不计，传输大文件利器！1、将配置文件写入frps.ini（服务端配置）# 服务端配置 [common] bind_addr = 0.0.0.0 bind_port = 7000 bind_udp_port = 7001 kcp_bind_port = 7000 # 开启控制面板 dashboard_port = 7500 dashboard_user = admin dashboard_pwd = admin2、在需要穿透的主机内网开启一个frpc客户端，将配置文件写入frpc.ini（客户端配置）# 连接服务器配置 [common] server_addr = ***.***.***.*** server_port = 7000 # 开启控制面板 admin_addr = 127.0.0.1 admin_port = 80 # 设置控制面板账号密码 admin_user = admin admin_pwd = admin # 设置需要穿透的名称，但是在服务器后台是看不到该连接的 [Mstsc] # 设置协议xtcp type = xtcp # 设置密钥 sk = abcdefg # 设置需要穿透的IP local_ip = 127.0.0.1 # 设置需要穿透的端口 local_port = 33893、在需要访问穿透主机的主机上开启一个frpc客户端，将配置文件写入frpc.ini（客户端配置）# 连接服务器配置 [common] server_addr = ***.***.***.*** server_port = 7000 # 开启控制面板 admin_addr = 127.0.0.1 admin_port = 80 # 设置控制面板账号密码 admin_user = admin admin_pwd = admin # 设置需要访问穿透的命名，可随意命名 [Mstsc_visitor] # 设置协议xtcp type = xtcp # 设置角色为visitor role = visitor # 设置被穿透主机的frpc穿透名称 server_name = Mstsc # 设置密钥 sk = abcdefg # 将穿透的IP地址绑定为本地地址 bind_addr = 127.0.0.1 # 将穿透的端口绑定为本地端口 bind_port = 33904、开启所有服务，在本地运行mstsc进行测试，连接上即可。

php curl简单图片生成base64编码使用方法：创建index.php 文件复制下面代码保存即可<?php $url=$_GET['url']; function curl_url($url,$type=0,$timeout=30){ $msg = ['code'=>2100,'status'=>'error','msg'=>'未知错误！']; $imgs= ['image/jpeg'=>'jpeg', 'image/jpg'=>'jpg', 'image/gif'=>'gif', 'image/png'=>'png', 'text/html'=>'html', 'text/plain'=>'txt', 'image/pjpeg'=>'jpg', 'image/x-png'=>'png', 'image/x-icon'=>'ico' ]; if(!stristr($url,'http')){ $msg['code']= 2101; $msg['msg'] = 'url地址不正确!'; return $msg; } $dir= pathinfo($url); $host = $dir['dirname']; $refer= $host.'/'; $ch = curl_init($url); curl_setopt ($ch, CURLOPT_REFERER, $refer); //伪造来源地址 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//返回变量内容还是直接输出字符串,0输出,1返回内容 curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);//在启用CURLOPT_RETURNTRANSFER的时候，返回原生的（Raw）输出 curl_setopt($ch, CURLOPT_HEADER, 0); //是否输出HEADER头信息 0否1是 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); //超时时间 $data = curl_exec($ch); $info = curl_getinfo($ch); curl_close($ch); $httpCode = intval($info['http_code']); $httpContentType = $info['content_type']; $httpSizeDownload= intval($info['size_download']); if($httpCode!='200'){ $msg['code']= 2102; $msg['msg'] = 'url返回内容不正确！'; return $msg; } if($type>0 && !isset($imgs[$httpContentType])){ $msg['code']= 2103; $msg['msg'] = 'url资源类型未知！'; return $msg; } if($httpSizeDownload<1){ $msg['code']= 2104; $msg['msg'] = '内容大小不正确！'; return $msg; } $msg['code'] = 200; $msg['status']='success'; $msg['msg'] = '资源获取成功'; if($type==0 or $httpContentType=='text/html') $msg['data'] = $data; $base_64 = base64_encode($data); if($type==1) $msg['data'] = $base_64; elseif($type==2) $msg['data'] = "data:{$httpContentType};base64,{$base_64}"; elseif($type==3) $msg['data'] = "<img src='data:{$httpContentType};base64,{$base_64}' />"; else $msg['msg'] = '未知返回需求！'; unset($info,$data,$base_64); return $msg; } $msg = curl_url($url,3); if($msg['status']=='success') echo $msg['data']; die; ?>调用方法：http://4dn.net/index.php?url=图片地址

效果图：代码：在源代码加上<i class="layui-icon layui-icon-tips" lay-tips="最大长度为16个文字" ></i>JS代码加上js代码$('*[lay-tips]').on('mouseenter', function(){ var content = $(this).attr('lay-tips'); this.index = layer.tips('<div style="padding: 10px; font-size: 14px; color: #eee;">'+ content + '</div>', this, { time: -1 ,maxWidth: 280 ,tips: [3, '#3A3D49'] }); }).on('mouseleave', function(){ layer.close(this.index); });
