站点页面上占用数据较多的一般是图片,图片的压缩比越大 ,访问页面速度会越快。wordpress下有相关的如WP Smush.it可以用于图片压缩,不过对于压缩比例和保真层度来看,不如tinypng 。其对wordpress也提供了相应的插件,不过免费版每个邮箱用户每月只提供五百个请求的压缩。这里结合其官方API ,做了一个shell版本的小工具,另外根据之前的php上传及tinypng的php API也写了一个web版的工具。
一、shell 版本
通过CURL请求,直接执行请求API URL时:
[root@361way tmp]# curl -i --user api:aSiDFS1VD1UfX7pIPdoDFSvoaYTaAvN --data-binary @delrepo2.png https://api.tinypng.com/shrink 执行结果 HTTP/1.1 100 Continue HTTP/1.1 201 Created Cache-Control: no-cache Compression-Count: 2 Content-Type: application/json; charset=utf-8 Date: Wed, 04 Mar 2015 03:13:34 GMT Location: https://api.tinypng.com/output/3molv9psquoqou8u.png Server: Apache/2 Strict-Transport-Security: max-age=31536000 X-Powered-By: Voormedia (voormedia.com/jobs) Content-Length: 158 Connection: keep-alive {"input":{"size":10628,"type":"image/png"},"output":{"size":7865,"type":"image/png","ratio":0.74,"url":"https://api.tinypng.com/output/3molv9psquoqou8u.png"}}
其中Location地址为执行后返回压缩后的图片在服务器上存放的地址。最后可以通过wget或curl 将该地址从远程取回来。
以下是写的shell 版,如下 :
#!/bin/bash Help() { cat << EOF ==================================================================== Usage: tinpny.sh input.png output.png ==================================================================== EOF } if [ # != 2 ];then Help else httpcont=`date +%s` url=`curl --silent -i --user api:aSiDFS1VD1UfX7pIPdoDFSvoaY_TaAvN --data-binary @1 https://api.tinypng.com/shrink |grep Location|awk '{print 2}'| tr -d '\r'` echourl wget url -O2 fi
二、php版
可以先参看PHP图片上传程序(完整版) ,这里使用的是PHP with curl API版,代码如下:
<?php /****************************************************************************** 参数说明: max_file_size : 上传文件大小限制, 单位BYTEdestination_folder : 上传文件路径 watermark : 是否附加水印(1为加水印,其他为不加水印); 使用说明: 1. 将PHP.INI文件里面的"extension=php_gd2.dll"一行前面的;号去掉,因为我们要用到GD库; 2. 将extension_dir =改为你的php_gd2.dll所在目录; ******************************************************************************/ //上传文件类型列表uptypes=array( 'image/jpg', 'image/jpeg', 'image/png', 'image/pjpeg', 'image/gif', 'image/bmp', 'image/x-png' ); max_file_size=2000000; //上传文件大小限制, 单位BYTEdestination_folder="uploadimg/"; //上传文件路径 watermark=2; //是否附加水印(1为加水印,其他为不加水印);watertype=1; //水印类型(1为文字,2为图片) waterposition=1; //水印位置(1为左下角,2为右下角,3为左上角,4为右上角,5为居中);waterstring="http://www.361way.com/"; //水印字符串 waterimg="361way.gif"; //水印图片imgpreview=1; //是否生成预览图(1为生成,其他为不生成); imgpreviewsize=1/2; //缩略图比例 ?> <?php function Compressimg(input,output) {key = "aSiDFS1VD1UfX7pIPdoDFSvoaY_TaAvN"; request = curl_init(); curl_setopt_array(request, array( CURLOPT_URL => "https://api.tinypng.com/shrink", CURLOPT_USERPWD => "api:" . key, CURLOPT_POSTFIELDS => file_get_contents(input), CURLOPT_BINARYTRANSFER => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_HEADER => true, /* Uncomment below if you have trouble validating our SSL certificate.

"/cacert.pem", CURLOPT_SSL_VERIFYPEER => true )); response = curl_exec(request); if (curl_getinfo(request, CURLINFO_HTTP_CODE) === 201) { /* Compression was successful, retrieve output from Location header. */headers = substr(response, 0, curl_getinfo(request, CURLINFO_HEADER_SIZE)); foreach (explode("\r\n", headers) asheader) { if (substr(header, 0, 10) === "Location: ") {request = curl_init(); curl_setopt_array(request, array( CURLOPT_URL => substr(header, 10), CURLOPT_RETURNTRANSFER => true, /* Uncomment below if you have trouble validating our SSL certificate. */ // CURLOPT_CAINFO => __DIR__ .

最后:
官方还提供了Java、ruby、node.js、python版的API,本来想使用下python版,不过本地的使用python版本是2.7版本的,而官方提供的是python3.x版本的。
