TinyPNG一个压缩PNG工具了,TinyPNG为了达到更小的文件大小进行了有损压缩,尽管在质量上有轻微的下降,但裸眼看不出来,下面我们就来看看linux中tinypng图片压缩的例子.
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'`
- echo $url
- wget $url -O $2
- 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BYTE
- $destination_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BYTE
- $destination_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(

- /* Uncomment below if you have trouble validating our SSL certificate.
- Download cacert.pem from: http://curl.haxx.se/ca/cacert.pem */
- // CURLOPT_CAINFO => __DIR__ . "/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) as $header) {
- if (substr($header, 0, 10) === "Location: ") {
- $request = curl_init();
- curl_setopt_array($request, array(
- CURLOPT_URL => substr($header, 10),
- CURLOPT_RETURNTRANSFER => true,
- /* Uncomment below if you have trouble validating our SSL certificate. */
- // CURLOPT_CAINFO => __DIR__ . "/cacert.pem",
- CURLOPT_SSL_VERIFYPEER => true
- ));
- file_put_contents($output, curl_exec($request));
- }
- }
- } else {
- print(curl_error($request));
- /* Something went wrong! */
- print("Compression failed");
- }
- }
- ?>

- echo " alt=\"图片预览:\r文件名:".$output."\r上传时间:\">";
- }
- }
- ?>
- </body>
- </html>
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.
