谷歌图书API通过ISBN检索 [英] Google books API searching by ISBN
问题描述
我试图找出如何通过国际标准书号使用谷歌图书API搜索一本书。我需要写一个程序，对于一个ISBN检索，然后打印出标题，作者和编辑。我试着用列表volumesList = books.volumes.list（）; 但是这并没有让我通过ISBN进行搜索，我没有看到一个方法来获取信息我需要（当ISBN被放置在它没有结果）。我现在所拥有的是：
JsonFactory jsonFactory =新JacksonFactory（）;
最终书籍书=新的图书（新NetHttpTransport（），jsonFactory）;
列表volumesList = books.volumes.list（9780262140874）; volumesList.setMaxResults（（长）2）; volumesList.setFilter（电子书）;
尝试
{
卷册= volumesList.execute（）;
对于（卷volume：volumes.getItems（））
{
VolumeVolumeInfo volumeInfomation = volume.getVolumeInfo（）;
的System.out.println（标题：+ volumeInfomation.getTitle（））;
的System.out.println（ID：+ volume.getId（））;
的System.out.println（作者：+ volumeInfomation.getAuthors（））;
的System.out.println（发布日期：+ volumeInfomation.getPublishedDate（））;
的System.out.println（）;
} }赶上（例外前）{
// TODO自动生成catch块
的System.out.println（剪掉wrork+ ex.toString（））;
}
如果任何人有关于如何使这种更有效的让我知道的任何建议。
新的code：
字符串titleBook =; ////////////////////////////////////////////////
尝试
{
BooksService booksService =新BooksService（UAH）;
字符串ISBN =9780262140874
网址URL =新的URL（http://www.google.com/books/feeds/volumes/?q=ISBN%3C+ ISBN +％3E）;
VolumeQuery volumeQuery =新VolumeQuery（URL）;
VolumeFeed volumeFeed = booksService.query（volumeQuery，VolumeFeed.class）;
VolumeEntry的BookInfo = volumeFeed.getEntries（）得到（0）; 的System.out.println（标题：+ bookInfo.getTitles（）得到（0））;
的System.out.println（ID：+ bookInfo.getId（））;
的System.out.println（作者：+ bookInfo.getAuthors（））;
的System.out.println（版本：+ bookInfo.getVersionId（））;
的System.out.println（描述：+ bookInfo.getDescriptions（）+\\ n）;
。titleBook = bookInfo.getTitles（）得到（0）的ToString（）;
titleBook =（字符串）titleBook.subSequence（titleBook.indexOf（=），titleBook.length（） - 1）;
}赶上（例外前）{的System.out.println（ex.getMessage（））;}
/////////////////////////////////////////////////
JsonFactory jsonFactory =新JacksonFactory（）;

的System.out.println（ID：+ bookInfomation.getId（））;
的System.out.println（作者：+ volumeInfomation.getAuthors（））;

的System.out.println（剪掉wrork+ ex.toString（））;

您使用的德precated数据API ？
使用书籍API V1 （从实验室），你可以使用查询
https://www.googleapis.com/books/v1/volumes?q=isbn:<your_isbn_here>
例如：
<一个href=\"https://www.googleapis.com/books/v1/volumes?q=isbn:0735619670\">https://www.googleapis.com/books/v1/volumes?q=isbn:0735619670
其ISBN来查询一本书。
您可能想看看谷歌的例子code：<一href=\"http://$c$c.google.com/p/google-api-java-client/source/browse/books-cmdline-sample/src/main/java/com/google/api/services/samples/books/cmdline/BooksSample.java?repo=samples\">BooksSample.java
I am trying to figure out how to search for a book by ISBN using the Google Books API. I need to write a program that searches for an ISBN then prints out the title, author, and edition. I tried using List volumesList = books.volumes.list(""); but that did not allow me to search by ISBN and I did not see a way to get the information I needed(when an ISBN was placed in it had no results) . What I have right now is:
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());
}
If anyone has any suggestions about how to make this more efficient let me know. New Code:
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());
}
Are you using the deprecated data API?
With Books API v1 (from Labs) you could use the query
https://www.googleapis.com/books/v1/volumes?q=isbn:<your_isbn_here>
for example
https://www.googleapis.com/books/v1/volumes?q=isbn:0735619670
to query a book by its ISBN.
You may want to look at Googles example code: BooksSample.java
