Linux下PHP5.2安装curl扩展支持https

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;     } }
