通过ISBN搜索Google图书API

我正在尝试找出如何使用Google Books

API通过ISBN搜索书籍。我需要编写一个程序来搜索ISBN，然后打印出标题，作者和版本。我尝试使用，List volumesList =

books.volumes.list("");但是这不允许我按ISBN进行搜索，而且我没有找到获取所需信息的方法（将ISBN放入其中时没有结果）。我现在所拥有的是：

    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());
    }

如果有人对如何提高效率有任何建议，请告诉我。新代码：

    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()+"\n");
        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());
    }

回答：

您是否正在使用不赞成使用的数据API？

借助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查询一本书。

您可能需要查看Google的示例代码：BooksSample.java

以上是 通过ISBN搜索Google图书API 的全部内容， 来源链接： utcz.com/qa/398654.html
