在蛋糕php 1.3中查看ctp我有以下代码:

$url = 'http://example.com/exmp/explus/books/view/'.$book['Book']['id'];

echo $this->Html->meta(array('property' => 'fb:app_id', 'content' => '*******'),'',array('inline'=>false));

echo $this->Html->meta(array('property' => 'og:type', 'content' => 'book'),'',array('inline'=>false));

echo $this->Html->meta(array('property' => 'og:url', 'content' => $url ),'',array('inline'=>false));

echo $this->Html->meta(array('property' => 'og:title', 'content' => $book['Book']['title']),'',array('inline'=>false));

echo $this->Html->meta(array('property' => 'og:description', 'content' => $book['Book']['title']),'',array('inline'=>false));

$imgurl = '../image/'.$book['Book']['id'];

echo $this->Html->meta(array('property' => 'og:image', 'content' => $imgurl ),'',array('inline'=>false)); ?>

当我发布它时,它会出现以下错误

{
   "error": {
      "message": "(#3502) Object at URL http://example.com/exmp/explus/books/view/234'   has   og:type of 'website'. The property 'book' requires an object of og:type 'book'. ",
      "type": "OAuthException",
      "code": …

在 java 1.8.0 中，我尝试替换 %，但它不匹配

  String str = "%28Sample text%29";

  str.replaceAll("%29", "\\)");

  str.replaceAll("%28", "\\(");
  System.out.println("Replaced string is " + str);

我已经尝试过所有这些将符号“%”替换为单词“百分比”，但没有任何效果对我有用。提前致谢。
