Google通过ISBN搜索API

Posted 2021-04-03

我试图找出如何使用Google Books API按ISBN搜索图书。我需要编写一个搜索ISBN的程序，然后打印出标题，作者和版本。我尝试使用List volumesList = books.volumes.list("");，但这不允许我按ISBN搜索，我没有找到一种方法来获取我需要的信息（当ISBN放入其中时没有结果）。我现在拥有的是：

    JsonFactory jsonFactory = new JacksonFactory();     
    final Books books = new Books(new NetHttpTransport(), jsonFactory);
    List volumesList = books.volumes.list("9780262140874");

    volumesList.setMaxResults((long) 2);

    volumesList.setFilter("ebooks");
    try
    {
        Volumes volumes = volumesList.execute();
        for (Volume volume : volumes.getItems()) 
        {
            VolumeVolumeInfo volumeInfomation = volume.getVolumeInfo();
            System.out.println("Title: " + volumeInfomation.getTitle());
            System.out.println("Id: " + volume.getId());
            System.out.println("Authors: " + volumeInfomation.getAuthors());
            System.out.println("date published: " + volumeInfomation.getPublishedDate());
            System.out.println();
        }

    } catch (Exception ex) {
        // TODO Auto-generated catch block
        System.out.println("didnt wrork "+ex.toString());
    }

如果有人有任何关于如何提高效率的建议让我知道。新守则：

    String titleBook="";

    ////////////////////////////////////////////////
    try
    {                               
        BooksService booksService = new BooksService("UAH");
        String isbn = "9780262140874";
        URL url = new URL("http://www.google.com/books/feeds/volumes/?q=ISBN%3C" + isbn + "%3E");
        VolumeQuery volumeQuery = new VolumeQuery(url);
        VolumeFeed volumeFeed = booksService.query(volumeQuery, VolumeFeed.class);
        VolumeEntry bookInfo=volumeFeed.getEntries().get(0);

        System.out.println("Title: " + bookInfo.getTitles().get(0));
        System.out.println("Id: " + bookInfo.getId());
        System.out.println("Authors: " + bookInfo.getAuthors());
        System.out.println("Version: " + bookInfo.getVersionId());
        System.out.println("Description: "+bookInfo.getDescriptions()+"
");
        titleBook= bookInfo.getTitles().get(0).toString();
        titleBook=(String) titleBook.subSequence(titleBook.indexOf("="), titleBook.length()-1);
    }catch(Exception ex){System.out.println(ex.getMessage());}
    /////////////////////////////////////////////////
    JsonFactory jsonFactory = new JacksonFactory();     
    final Books books = new Books(new NetHttpTransport(), jsonFactory);
    List volumesList = books.volumes.list(titleBook);   
    try
    {
        Volumes volumes = volumesList.execute();
        Volume bookInfomation= volumes.getItems().get(0);

        VolumeVolumeInfo volumeInfomation = bookInfomation.getVolumeInfo();
        System.out.println("Title: " + volumeInfomation.getTitle());
        System.out.println("Id: " + bookInfomation.getId());
        System.out.println("Authors: " + volumeInfomation.getAuthors());
        System.out.println("date published: " + volumeInfomation.getPublishedDate());
        System.out.println();

    } catch (Exception ex) {
        System.out.println("didnt wrork "+ex.toString());
    }

答案

你在使用deprecated data API吗？

使用Books API v1（来自Labs），您可以使用查询

https://www.googleapis.com/books/v1/volumes?q=isbn:<your_isbn_here>

例如

https://www.googleapis.com/books/v1/volumes?q=isbn:0735619670

通过其ISBN查询书籍。

您可能需要查看Googles示例代码：BooksSample.java

另一答案

如果我理解你的任务，你不能像开发者指南developer guide中所说的那样尝试。你可以这样做：

BooksService booksService = new BooksService("myCompany-myApp-1");
myService.setUserCredentials("[e-mail]", "secretPassword");

String isbn = "9780552152679";
URL url = new URL("http://www.google.com/books/feeds/volumes/?q=ISBN%3C" + isbn + "%3E");
VolumeQuery volumeQuery = new VolumeQuery(url);
VolumeFeed volumeFeed = booksService.query(volumeQuery, VolumeFeed.class);

// using an ISBN in query gives only one entry in VolumeFeed
List<VolumeEntry> volumeEntries = volumeFeed.getEntries();
VolumeEntry entry = volumeEntries.get(0);

现在使用VolumeEntry api查找所需的getXXXX（）并在您的代码中使用它。我希望它能帮助您解决问题。

另一答案

$("form").submit(
  function(e) {
    e.preventDefault();
    var isbn = $('#ISBN').val();
    var isbn_without_hyphens = isbn.replace(/-/g, "");
    var googleAPI = "https://www.googleapis.com/books/v1/volumes?q=" + isbn_without_hyphens;
    $.getJSON(googleAPI, function(response) {
      if (typeof response.items === "undefined") {
        alert("No books match that ISBN.")
      } else {
        $("#title").html(response.items[0].volumeInfo.title);
        $("#author").html(response.items[0].volumeInfo.authors[0]);
        $("#publishedDate").html(response.items[0].volumeInfo.publishedDate);
      }
    });
  }
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
  <strong>Enter ISBN:</strong> <input type="text" id="ISBN" value="9781407170671">
  <input type="submit" id="submit">
</form>
Title: <span id="title"></span>
<br> Author: <span id="author"></span>
<br> Publication date: <span id="publishedDate"></span>
