使用Google Books API [英] Using Google Books API

问题描述

我在使用Google Books API时遇到问题

I'm having trouble using the Google Books API

我没有使用JSON的经验.

I am inexperienced in working with JSON.

我的表单:

<form action="action.php" method="POST">
<div class="form-group">
    <div class="campos">
        <label>
         Search
        </label>
        <input type="text" name="search"  style="margin-right: 10px; width:250px; float:left" class="input-field" placeholder="Title, Author..."  />    
        <button type="submit" id="search" class="btn btn-default">Search</button>
    </div>
</div>

我的动作:

$var1 = "https://www.googleapis.com/books/v1/volumes?q=";
$var2 = urlencode($_POST['search']);
$str = str_replace(" ", "+", $var2);
$page = $var1.$str;
header ("location:$page");
$data = file_get_contents($page);
$data = json_decode($page, true);

因此，运行此代码将向我返回一个包含以下内容的json文件:

So running this code is returned to me one json file containing something like:

{
 "kind": "books#volumes",
 "totalItems": 584,
 "items": [
  {
  "kind": "books#volume",
  "id": "NkHwo2hKW6YC",

  "selfLink": "https://www.googleapis.com/books/v1/volumes/NkHwo2hKW6YC",

   }
  ],
   "readingModes": {

  },

    },

  "canonicalVolumeLink": "http://books.google.com.br/books/about/viagem_ao_redor_da_lua.html?hl=&id=NkHwo2hKW6YC"
 },
 "saleInfo": {
  "country": "BR",
  "saleability": "NOT_FOR_SALE",
  "isEbook": false
 },
 "accessInfo": {
  "country": "BR",
  "viewability": "PARTIAL",
  "embeddable": true,
  "publicDomain": false,

  "epub": {
    "isAvailable": false
  },

   "isAvailable": false
  },
  "webReaderLink": "http://books.google.com.br/books/reader?id=NkHwo2hKW6YC&hl=&printsec=frontcover&output=reader&source=gbs_api",
  "accessViewStatus": "SAMPLE",
  "quoteSharingAllowed": false
 },
  "searchInfo": {
  "textSnippet": "Em uma época que não se conhecia a tecnologia, Verne consegue prever em forma de aventura, uma viagem pelo espaço até a Lua."
 }
 },
 ]  
}

我需要通过php显示一些此类信息.

I need to show some of this information by php.

推荐答案

请您检索JSON信息，这是最困难的部分.

Well you ale retrieving the JSON info so that's the hard part.

为了通过php打印数据，请尝试以下操作；

In order to print the data via php try something like the following;

$page = file_get_contents($page);

$data = json_decode($page, true);

echo "Title = " . $data['items'][0]['volumeInfo']['title'];
echo "Authors = " . @implode(",", $data['items'][0]['volumeInfo']['authors']);    
echo "Pagecount = " . $data['items'][0]['volumeInfo']['pageCount'];
