解决Gravatar头像、Google fonts和Google ajax不能使用的方法

吾爱互联 · 发表于 2015-5-14 13:49:12

因为国内google打不开了所以导致像国外的　Gravatar头像、Google fonts和Google ajax这些接口都不能使用了，　下文我们就一起来看解决办法．
</div>Gravatar头像现在大陆地区偶尔无法访问，还有各种google服务也用不了。对于“一枚程序员”来说是不能容忍的。 
于是麦葱弄了个解决之法——使用nginx反向代理Gravatar头像、Google fonts和Google ajax。 
反代之前需要确定nginx已经安装了proxy_cache模块并配置好路径及参数。
 
下面是麦葱在nginx.conf中配置的代码：
 
http 
{ 
    #其他代码...#
    proxy_connect_timeout 5; 
    proxy_read_timeout 60; 
    proxy_send_timeout 5; 
    proxy_buffer_size 16k; 
    proxy_buffers 4 64k; 
    proxy_busy_buffers_size 128k; 
    proxy_temp_file_write_size 128k; 
    proxy_temp_path /tmp/nginx_proxy_temp 1 2;  #临时文件目录
    #其他代码...# 
}
 
然后是单独的配置文件gravatar.conf，带#的需要你进行相应修改：
 
proxy_cache_path  /tmp/nginx_proxy_cache/gravatar levels=1:2 keys_zone=GRAVATAR:32m inactive=7d max_size=1g; #缓存路径
server { 
    listen 80; 
    server_name gravatar.yuxiaoxi.com; #绑定的域名
    location  / { 
        proxy_cache GRAVATAR; 
        proxy_cache_key "$scheme://$host$<a href="/tags.php/request/" target="_blank">request</a>_uri"; 
        proxy_cache_valid 200 304 7d; 
        proxy_cache_valid 301 3d; 
        proxy_cache_valid any 10s;
        proxy_pass http://0.gravatar.com; #反代的域名 
        proxy_pass_header Server; 
        proxy_redirect off; 
        proxy_set_header Host 0.gravatar.com; 
        proxy_set_header X-Real-IP $remote_addr; 
        proxy_set_header X-Scheme $scheme; 
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    }
    location ~ /purge(/.*) { 
        allow 127.0.0.1; 
        deny all; 
        proxy_cache_purge GRAVATAR "$scheme://$host$1"; 
    }
    location ~* ＼.(ftpquota|htaccess|htpasswd|asp|aspx|jsp|asa|mdb)?$ { 
        deny all; 
    }
    access_log /home/wwwroot/gravatar/log/access.log combined; #access_log end 
    error_log /home/wwwroot/gravatar/log/error.log crit; #error_log end 
}

Google fonts和Google ajax配置差不多，我就不贴出来了，请在文尾查看下载链接。 
你也可以直接使用麦葱弄好的，支持SSL哦~：
 
将www.gravatar.com,cn.gravatar.com,0.gravatar.com,1.gravatar.com,2.gravatar.com替换为gravatar.yuxiaoxi.com； 
将fonts.gstatic.com替换为fonts.yuxiaoxi.com； 
将ajax.googleapis.com替换为ajax.yuxiaoxi.com；
 
BYMT主题用户修改办法：
 
1、打开/wp-content/themes/BYMT/目录下的functions.php文件 
2、搜索bymt_get_avatar，将gravatar.duoshuo.com替换为gravatar.yuxiaoxi.com 
3、搜索bymt_avatar，从//获取头像及缓存开始，到//<a href="/tags.php/%B7%D6%D2%B3/" target="_blank">分页</a>功能上一行，替换为： 
// 通过curl获取内容 
function bymt_curl_contents($url){ 
    $ch = curl_init(); 
    <a href="/tags.php/curl_setopt/" target="_blank">curl_setopt</a>($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    $response =  curl_exec($ch); 
    curl_close($ch);
    /** 请求为空 **/ 
    if(empty($response)){ 
        $response = ''; 
    }
    return $response; 
}
// 写文件 
function bymt_write_file($path, $data, $mode = 'wb') { 
    if ( ! $fp = @<a href="/tags.php/fopen/" target="_blank">fopen</a>($path, $mode)) { 
        return false; 
    }
    flock($fp, LOCK_EX); 
    fwrite($fp, $data); 
    flock($fp, LOCK_UN); 
    fclose($fp);
    return true; 
}
//获取头像及缓存 
function bymt_avatar($email, $size='50', $time='1209600') { // 默认尺寸50px 有效期14天 
    if ( !is_numeric($size) ) $size = '50'; 
    if ( !is_numeric($time) ) $time = '1209600'; 
    if(bymt_c('avatar_cache') ){ 
        $mailhash = md5(strtolower(trim($email))); 
        $default = urlencode(get_option('avatar_default')); 
        $rating = get_option('avatar_rating'); 
        $ava_path = ABSPATH . 'avatar/' . $mailhash. '-' . $size . '.jpg'; 
        if ( ! file_exists($ava_path) || filesize($ava_path) < 1 || (time() - filemtime($ava_path)) > $time) { 
            $ava_url = 'http://gravatar.yuxiaoxi.com/avatar/'.$mailhash.'?s='.$size.'&d='.$default.'&r='.$rating; 
            $avadata = bymt_curl_contents($ava_url); 
            bymt_write_file($ava_path, $avadata); 
        } else { 
            $ava_url = esc_url(home_url('/avatar/')) . $mailhash. '-' . $size . '.jpg'; 
        } 
        return '<img src="'.$ava_url.'" alt="avatar" class="avatar avatar-'.$size.' photo" height="'.$size.'" width="'.$size.'" />'; 
    }else{ 
        return get_avatar( $email, $size ); 
    } 
}
4、打开/wp-<a href="/tags.php/include/" target="_blank">include</a>s/script-loader.php，搜索ajax.googleapis.com替换为ajax.yuxiaoxi.com，搜索 fonts.gstatic.com替换为fonts.yuxiaoxi.com； 
搞定收工！
