Composer在windows下的安装使用

Composer是 PHP 用来管理依赖（dependency）关系的工具。你可以在自己的项目中声明所依赖的外部工具库（libraries），Composer 会帮你安装这些依赖的库文件。
官网：https://getcomposer.org/
中文相关网站：http://www.phpcomposer.com/
一、下载安装文件安装，https://getcomposer.org/Composer-Setup.exe
二、在php.ini文档中打开extension=php_openssl.dll
三、下载php_ssh2.dll、php_ssh2.pdb，http://windows.php.net/downloads/pecl/releases/ssh2/0.12/
四、把php_ssh2.dll、php_ssh2.pdb文件放php的ext文件夹
五、重启nginx及php
六、执行cmd，运行：composer -V 能看到版本，表示安装成功

33 配置wampserver

权限问题配置 permission

listen 8081
<VirtualHost *:8081>
    ServerName localhost
    DocumentRoot C:/Hirson/wamp64/www/zhibo
    <Directory  "C:/Hirson/wamp64/www/zhibo">
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    allow from all
    </Directory>
</VirtualHost>

<VirtualHost *:80>
     DocumentRoot "C:\wamp\www"      
     ServerName localhost       
</VirtualHost>


listen 88
<VirtualHost *:88> 
ServerAdmin webmaster@dummy-host2.example.com
 DocumentRoot "C:/wamp/www/test" 
ServerName www.123.com 
<Directory "C:/wamp/www/test">
Options Indexes FollowSymLinks
    AllowOverride None
</Directory>
</VirtualHost>

在Apache2.4下面会出现403的问题

You don't have permission to access / on this server. Apache/2.4.18 (Win32)

需要设置
require all granted

listen 8050
<VirtualHost *:8050> 
ServerAdmin webmaster@dummy-host2.example.com
 DocumentRoot "E:/web/TP5_Splider" 
ServerName www.123.com 
<Directory "E:/IIS_web/TP5_Splider">
     Options Indexes FollowSymLinks  
     AllowOverride None
     Order deny,allow
     allow from all
     require all granted
</Directory>
</VirtualHost>

apache 配置接口代理

• 1.找到Apache目录下的httpd.conf文件，将
  LoadModule proxy_module modules/mod_proxy.so和
  LoadModule proxy_http_module modules/mod_proxy_http.so前的注释去掉、
• 2 配置信息

 <VirtualHost *:80>  
       ServerAdmin test@test.com  
       ServerName www.test.com  
  
       ProxyRequests Off  
  <Proxy *>  
       Order deny,allow  
       Allow from all  
   </Proxy>  
       ProxyPass /test    http://192.168.1.2:8080/test  
       ProxyPassReverse /test   http://192.168.1.2:8080/test  
</VirtualHost>  

接口代理

 
<?php

    header('Content-Type:text/json;charset=utf-8');//设置返回文件的类型
    header('Access-Control-Allow-Origin: *');//设置允许所有跨域
    $url= $_SERVER['REQUEST_URI']; //获取url localhost后面部分
        if($url=='/'){
        $arrs["msg"]="请填写你要请求的参数apiProxy=";
        echo json_encode($arrs);
        die();
    }else{
        $arr=explode('apiProxy=',$url); 
        if($arr[1]== null){
        $arrs["msg"]="代理参数请求错误";
        echo json_encode($arrs);
        die();
    }
        $data =file_get_contents($arr[1]);
        echo $data;
    }
