一、问题描述:
使用PHP中的库函数file_get_contents时出现Unable to find the wrapper "https"错误解决
出现这个错误的原因很简单,因为你php配置出了问题,先说一下为什么会出现这个问题,原因是你的URL地址的前缀是https;在URL前加https前缀表明是用SSL加密的。 你的电脑与服务器之间收发的信息传输将更加安全。Web服务器启用SSL需要获得一个服务器证书并将该证书与要使用SSL的服务器绑定。
http和https使用的是完全不同的连接方式,用的端口也不一样,前者是80,后者是443。http的连接很简单,是无状态的。HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议要比http协议安全。读完这段话你也应该知道原因了。因为你的php配置中的加密模块并没有打开。
二、问题解决方案
(1)重新编译openssl扩展
(2)php7 源码目录路径:/home/www/demo/php-7.0.22/
(3)进入openssl的扩展目录:/home/www/demo/php-7.0.22/ext/openssl
(4)运行phpize生成编译的配置文件,可能会出现以下错误
Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module
解决办法:在当前目录复制一份编译需要的文件,执行命令: cp ./config0.m4 ./config.m4 即可,继续以上的操作,生成通过
www@tinywan:~/demo/php-7.0./ext/openssl$ /opt/php7.0.22/bin/phpize
Configuring for:
PHP Api Version:
Zend Module Api No:
Zend Extension Api No:
(5)检测编译文件是否通过
sudo ./configure --with-openssl --with-php-config=/opt/php7.0.22/bin/php-config
(6)开始编译
遇到以下错误
/usr/include/openssl/conf.h::: note: expected 'struct lhash_st_CONF_VALUE *' but argument is of type 'int *' make: *** [ext/openssl/openssl.lo] Error
注意:我踩的一个坑,安装的是php7.0.22的版本,结果我下载的7.0.9的版本,这样子也会提示以下错误信息
Make sure that you run '/opt/php7.0.22/bin/phpize' in the top level source directory of the module
安装以下扩展
sudo apt-get install openssl
sudo apt-get install libssl-dev
继续编译
make cp ./.libs/openssl.so /home/www/demo/php-7.0./ext/openssl/modules/openssl.so
cp ./.libs/openssl.lai /home/www/demo/php-7.0./ext/openssl/modules/openssl.la
PATH="$PATH:/sbin" ldconfig -n /home/www/demo/php-7.0./ext/openssl/modules
----------------------------------------------------------------------
Libraries have been installed in:
/home/www/demo/php-7.0./ext/openssl/modules If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf' See any operating system documentation about shared libraries for
more information, such as the ld() and ld.so() manual pages.
---------------------------------------------------------------------- Build complete.
Don't forget to run 'make test'.
安装
www@ubuntu1:~/demo/php-7.0./ext/openssl$ sudo make install
[sudo] password for www:
Installing shared extensions: /opt/php7.0.22/lib/php/extensions/no-debug-non-zts-/
(7)修改配置php.ini文件:sudo vim /opt/php7.0.22/etc/php.ini 添加以下代码
extension=/opt/php7.0.22/lib/php/extensions/no-debug-non-zts-/openssl.so
(8)重启服务器,查看扩展是否安装成功
(9)安装结束
