阿里云短信发送代码封装 忽见某一高手为了实现发送短信，竟然引入了整个aliyunsdk，我一阵语塞。。。在这里分享一个项目中调用阿里云短信发送的PHP实现吧。注意：下面的类中 namespace 和 config 均为伪代码，请自行替换。/** * 阿里云短信 * @package rehiy\util * @author 若海<https://www.rehiy.com> */ namespace rehiy\util; use rehiy\Config; use rehiy\Exception; class AliyunSms { protected $accessKeyId = ''; protected $accessKeySecret = ''; protected $signName = ''; protected $templateCode = ''; protected $apiUrl = 'http://dysmsapi.aliyuncs.com/'; public function __construct() { $this->accessKeyId = Config::get('sms_appid'); $this->accessKeySecret = Config::get('sms_secret'); $this->signName = Config::get('sms_signame'); $this->templateCode = Config::get('sms_template_code'); } public function send(string $phone, array $data) { $params = [ 'AccessKeyId' => $this->accessKeyId, 'Action' => 'SendSms', 'Format' => 'JSON', 'PhoneNumbers' => $phone, 'RegionId' => 'cn-hangzhou', 'SignName' => $this->signName, 'SignatureMethod' => 'HMAC-SHA1', 'SignatureNonce' => uniqid(mt_rand(0, 0xffff), true), 'SignatureVersion' => '1.0', 'Timestamp' => gmdate('Y-m-d\TH:i:s\Z'), 'Version' => '2017-05-25', 'TemplateCode' => $this->templateCode, 'TemplateParam' => json_encode($data, JSON_UNESCAPED_UNICODE), ]; ksort($params); $sortedQuery = http_build_query($params, '', '&', PHP_QUERY_RFC3986); $signature = "POST&%2F&" . rawurlencode($sortedQuery); $signature = rawurlencode( base64_encode(hash_hmac('sha1', $signature, $this->accessKeySecret .

为废弃的 openssl-1.0.2 填坑（.a转.so） 先吐个槽：话说php7已经大行其道，php8也开测了，某擎微平台却还运行在已经停止支持的php5上，而php5更是依赖了已废弃的openssl-1.0.x帮小伙伴编译php5环境的时候，发现工具链已经无法很好的编译出openssl的lib库。编译出来的libcrypto.so竟然是0字节，其他文件均正常。调整各项参数，重新编译均无法解决。最后，只好拿libcrypto.a开刀，尝试编译出正确的.so文件。ar -x libcrypto.a gcc -shared *.o -o libcrypto.so rm *.o工作原理： .so文件是动态库文件，.a是由一系列.o 文件通过ar程序打包在一起的静态库，要把它转成动态库只需先解开，生成一堆.o文件，再通过编译器（gcc 或 ifort）编成动态库即可。

自动生成百度云加速 IP 白名单 百度云加速的ip段非常之多，官方给了一个帖子来列出这些ip，获取起来十分不便。倍感痛苦的我，最终还是决定写个PHP脚本自动更新Nginx的real_ip规则。其他规则也可以参考修改。最新源码参看：https://github.com/rehiy/baidu-yunjiasu-ipbaidu.txt 复制自百度云加速官方文档<?php $bdip4 = read_ipv4_list('baidu.txt'); $cfip4 = read_ipv4_list('https://www.cloudflare.com/ips-v4'); $cfip6 = read_ipv6_list('https://www.cloudflare.com/ips-v6'); $list = array_merge( ['# su-ipv4'], $bdip4, ['# cf-ipv4'], $cfip4, ['# cf-ipv6'], $cfip6 ); echo '写入配置文件: '; make_nginx_waf_ip($list); echo '...1'; make_nginx_real_ip_conf($list); echo '...2'; make_nginx_geoip_proxy($list); echo "...3..."; /////////////////////////////////////////////////////////// function make_nginx_waf_ip($list) { $rets = []; foreach ($list as $ip) { if (preg_match('/^#/', $ip)) { $rets[] = $ip; } else { $rets[] = "allow {$ip};"; } } $rets[] = '# default'; $rets[] = 'deny all;'; $text = implode("\n", $rets); file_put_contents('./dist/nginx_waf_ip.conf', $text); } function make_nginx_real_ip_conf($list) { $rets = []; foreach ($list as $ip) { if (preg_match('/^#/', $ip)) { $rets[] = $ip; } else { $rets[] = "set_real_ip_from {$ip};"; } } $text = implode("\n", $rets); file_put_contents('./dist/nginx_real_ip.conf', $text); } function make_nginx_geoip_proxy($list) { $rets = []; foreach ($list as $ip) { if (preg_match('/^#/', $ip)) { $rets[] = $ip; } else { $rets[] = "geoip_proxy {$ip};"; } } $rets[] = '# recursive'; $rets[] = 'geoip_proxy_recursive on;'; $text = implode("\n", $rets); file_put_contents('./dist/nginx_geoip_proxy.conf', $text); } /////////////////////////////////////////////////////////// function read_ipv4_list($site) { echo "读取远程数据: {$site}\n"; $html = file_get_contents($site); if (!preg_match_all('/\d+\.\d+\.\d+\.\d+\/\d+/', $html, $list)) { exit("读取数据失败: {$site}\n"); } return sort_ipv4_list($list[0]); } function read_ipv6_list($site) { echo "读取远程数据: {$site}\n"; $html = file_get_contents($site); if (!preg_match_all('/[0-9:a-f]+\/\d+/', $html, $list)) { exit("读取数据失败: {$site}\n"); } return $list[0]; } function sort_ipv4_list($list) { $rets = []; foreach (array_unique($list) as $val) { $ip = ip2long(explode('/', $val)[0]); $ip = sprintf('%u', floatval($ip)); $rets[$ip] = $val; } ksort($rets); return array_values($rets); }

设置 CORS 实现跨域请求 一、使用php代码实现# # CORS config for php # Code by rehiy[[email protected]] # function make_cors($origin = '*') { $request_method = $_SERVER['REQUEST_METHOD']; if ($request_method === 'OPTIONS') { header('Access-Control-Allow-Origin:'.$origin); header('Access-Control-Allow-Credentials:true'); header('Access-Control-Allow-Methods:GET, POST, OPTIONS'); header('Access-Control-Max-Age:1728000'); header('Content-Type:text/plain charset=UTF-8'); header('Content-Length: 0',true); header('status: 204'); header('HTTP/1.0 204 No Content'); } if ($request_method === 'POST') { header('Access-Control-Allow-Origin:'.$origin); header('Access-Control-Allow-Credentials:true'); header('Access-Control-Allow-Methods:GET, POST, OPTIONS'); } if ($request_method === 'GET') { header('Access-Control-Allow-Origin:'.$origin); header('Access-Control-Allow-Credentials:true'); header('Access-Control-Allow-Methods:GET, POST, OPTIONS'); } }二、使用nginx配置实现# # CORS config for nginx # Code by rehiy[[email protected]] # location / { set $origin '*'; if ($request_method = 'OPTIONS') { add_header 'Access-Control-Allow-Origin' $origin; # # Om nom nom cookies # add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; # # Custom headers and headers various browsers *should* be OK with but aren't # add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; # # Tell client that this pre-flight info is valid for 20 days # add_header 'Access-Control-Max-Age' 1728000; add_header 'Content-Type' 'text/plain charset=UTF-8'; add_header 'Content-Length' 0; return 204; } if ($request_method = 'POST') { add_header 'Access-Control-Allow-Origin' $origin; add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; } if ($request_method = 'GET') { add_header 'Access-Control-Allow-Origin' $origin; add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; } }

Ubuntu 修复 grub 开机引导 安装完Ubuntu忘记写入引导文件，或者使用工具调整分区后，很容易出现grub损坏无法进入系统的情况。也可能是由于分区调整或分区UUID改变造成grub2不能正常启动，从而进入修复模式了（grub rescue)，也称救援模式。error : unknow filesystem grub rescue >在救援模式下只有很少的命令可以用:(1)set 查看环境变量，这里可以查看启动路径和分区。 (2)ls 查看设备 (3)insmod 加载模块 (4)root 指定用于启动系统的分区,在救援模式下设置grub启动分区 (5)prefix 设定grub启动路径具体修复步骤如下：1、查看分区：grub rescue> ls //回车，会出现如下字样： (hd0) (hd0,msdos6) (hd0,msdos5) (hd0,msdos1)2、寻找ubuntu分区：若包含/bin以及/sbin等目录，表示为主分区。若包含/boot/grub或者/grub，即为启动分区。grub rescue> ls (hd0,msdos1)/3、修改启动分区：假如你找到的主分区为(hd0,msdos6)，grub所在路径是(hd0,msdos1)/grubgrub rescue > root=hd0,msdos1 grub rescue > prefix=/grub //grub路径设置 grub rescue > set root=hd0,msdos1 grub rescue > set prefix=(hd0,msdos1)/grub grub rescue > insmod normal //启动normal启动 grub rescue > normal之后你就会看到熟悉的启动菜单栏了4、进入命令行启动ubuntu进入系统启动选项界面后还是进不去，按C进入命令行模式grub > set root=hd0,msdos1 grub > set prefix=(hd0,msdos1)/grub grub > linux /vmlinuz-xxx-xxx root=/dev/sda6 //按Tab键自动补全，若acpi有问题,在最后添加acpi=off grub > initrd /initrd.img-xxx-xxx grub > boot这样就可以进入了5、进入ubuntu修复grubsudo update-grub sudo grub-install /dev/sda6、重启，搞定！！
