问题：
线上运行的 LNMP 服务器，因历史原因安装的 curl 模块只支持 http，不支持 https。类似请求或 POST 微信接口（小程序），都无法正常使用。
一、解决方法：
编译安装 curl，重新编译 php，使 php 的 curl 模块支持 https。
cd /data0/software
1、下载安装 curl
wget http://curl.haxx.se/download/curl-7.44.0.tar.gz
tar zxvf curl-7.44.0.tar.gz
cd curl-7.44.0
./configure –prefix=/usr/local/curl –with-gssapi –enable-tls-srp –with-libmetalink
make && make install
2、重新编译 php
查找系统之前的 php 编译参数
/usr/local/webserver/php/bin/php -i | grep configure
./configure –prefix=/usr/local/webserver/php –with-config-file-path=/usr/local/webserver/php/etc –with-MySQL=/usr/local/mysql –with-mysqli=/usr/local/mysql/bin/mysql_config –with-iconv-dir=/usr/local –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr/ –enable-xml –disable-rpath –enable-discard-path –enable-safe-mode –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fastcgi –enable-fpm –enable-force-cgi-redirect –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –with-xmlrpc –enable-zip –enable-soap
取消原来的 –with-curl
替换为：–with-curl=/usr/local/curl
cd /data0/software/php-5.2.17
# 进入 php 安装包目录（注意 php 版本要和之前一样）
./configure –prefix=/usr/local/webserver/php –with-config-file-path=/usr/local/webserver/php/etc –with-mysql=/usr/local/mysql –with-mysqli=/usr/local/mysql/bin/mysql_config –with-iconv-dir=/usr/local –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr/ –enable-xml –disable-rpath –enable-discard-path –enable-safe-mode –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl=/usr/local/curl –with-curlwrappers –enable-mbregex –enable-fastcgi –enable-fpm –enable-force-cgi-redirect –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –with-xmlrpc –enable-zip –enable-soap
/usr/local/webserver/php/sbin/php-fpm stop
# 不确定是否要关闭，但还是关闭再编辑吧
make ZEND_EXTRA_LIBS=’-liconv’
make install
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/php/bin/php -i|grep curl
## 有 libcurl/7.44.0 OpenSSL/1.0.1e 字样了。说明成功了。
二、还有一种方式，不变服务器环境下，使用 socket 方式来请求或 post 数据，方法如下：
function socketRequest($url, $data =””, $method =””, $cookieFile = “”, $connectTimeout = 1){
$return = ”;
$matches = parse_url($url);
!isset($matches[‘host’]) && $matches[‘host’] = ”;
!isset($matches[‘path’]) && $matches[‘path’] = ”;
!isset($matches[‘query’]) && $matches[‘query’] = ”;
!isset($matches[‘port’]) && $matches[‘port’] = ”;
$host = $matches[‘host’];
$path = $matches[‘path’] ? $matches[‘path’].($matches[‘query’] ? ‘?’.$matches[‘query’] : ”) : ‘/’;
$port = !empty($matches[‘port’]) ? $matches[‘port’] : 443;
$conf_arr = array(
‘limit’ => 0,
‘post’ => $data,
‘cookie’ => $cookieFile,
‘ip’ => ”,
‘timeout’ => $connectTimeout,
‘block’ => TRUE,
);
foreach ($conf_arr as $k=>$v) ${$k} = $v;
if($post) {
if(is_array($post))
{
$postBodyString = ”;
foreach ($post as $k => $v) $postBodyString .= “$k=” . urlencode($v) . “&”;
$post = rtrim($postBodyString, ‘&’);
}
$out = “POST $path HTTP/1.0\r\n”;
$out .= “Accept: */*\r\n”;
//$out .= “Referer: $boardurl\r\n”;
$out .= “Accept-Language: zh-cn\r\n”;
$out .= “Content-Type: application/x-www-form-urlencoded\r\n”;
$out .= “User-Agent: “.$_SEVER[‘HTTP_USER_AGENT’].”\r\n”;
$out .= “Host: $host\r\n”;
$out .= ‘Content-Length: ‘.strlen($post).”\r\n”;
$out .= “Connection: Close\r\n”;
$out .= “Cache-Control: no-cache\r\n”;
$out .= “Cookie: $cookie\r\n\r\n”;
$out .= $post;
} else {
$out = “GET $path HTTP/1.0\r\n”;
$out .= “Accept: */*\r\n”;
//$out .= “Referer: $boardurl\r\n”;
$out .= “Accept-Language: zh-cn\r\n”;
$out .= “User-Agent: “.$_SEVER[‘HTTP_USER_AGENT’].”\r\n”;
$out .= “Host: $host\r\n”;
$out .= “Connection: Close\r\n”;
$out .= “Cookie: $cookie\r\n\r\n”;
}
$fp = @fsockopen(‘ssl://’.($ip ? $ip : $host), $port, $errno, $errstr, $timeout);
if(!$fp) {
return ”;
} else {
stream_set_blocking($fp, $block);
stream_set_timeout($fp, $timeout);
@fwrite($fp, $out);
$status = stream_get_meta_data($fp);
if(!$status[‘timed_out’]) {
while (!feof($fp)) {
if(($header = @fgets($fp)) && ($header == “\r\n” || $header == “\n”)) {
break;
}
}
$stop = false;
while(!feof($fp) && !$stop) {
$data = fread($fp, ($limit == 0 || $limit > 8192 ? 8192 : $limit));
$return .= $data;
if($limit) {
$limit -= strlen($data);
$stop = $limit <= 0;
}
}
}
@fclose($fp);
return $return;
}
}
