PHP实现Markdown文章上传到七牛图床的实例内容

$ mkdir markdown-images-to-qiniu

$ cd markdown-images-to-qiniu

$ composer require qiniu/php-sdk

?php

require 'vendor/autoload.php';

use Qiniu\Auth;

use Qiniu\Storage\UploadManager;

// 1. 读取 `makrdown` 文件

$file = $argv[1];

if(! file_exists($file) ){

  return "找不到文件{$file}";

}

$orginalContent = file_get_contents($file);

// 2. 正则匹配出所有的图片

preg_match_all(

  '/\!\[.*\]\(.+\)/',

  $orginalContent,

  $matches,

  PREG_PATTERN_ORDER

);

$mdImageArr = $matches[0];

if(! count($mdImageArr) ){

  return "无需上传图片";

}

// 3. 依次上传图片

$accessKey = '你的 AccessKey';

$secretKey = '你的 SecretKey';

$bucket = '你的七牛空间名'; // eg. mindgeek

$url = "空间所绑定的域名"; // eg. http://qiniu.site.com

  $localPath = mb_substr($image, $start, -1);

  $extension = pathinfo($localPath)['extension'];

  $uploadPath = uniqid(). ".". $extension;

  list($ret, $error) = $uploadMgr->putFile($token, $uploadPath, $localPath);

  if(! $error ){

    // 4. 将文章图片的地址替换为图床地址

    $content = str_replace($localPath, $url.$uploadPath, $content);

    echo "{$uploadPath} 上传成功。\n";

  } else {

// 5. 保存替换后的文章
