Google Web API

遅ればせながらGoogle Web APIで遊んでみました。

http://www.google.com/apis/

手順通りに

1. Debeloper's Kitをダウンロード

2. Google Accountを作る

3.発行されたライセンス・キーを使ってプログラムを書く

を順番にやってみることに。今回はJavaのAPIを使ってみました。

やってみたのは、以下のクラスを使って

GoogleSearch
GoogleSearchResult
GoogleSearchResultElement

ググッて、結果を得るということ。
以下の例では"Rugby"をググってみるコード

package com.hidekoji.GoogleTest;

import com.google.soap.search.GoogleSearch;
import com.google.soap.search.GoogleSearchResult;
import com.google.soap.search.GoogleSearchFault;
import com.google.soap.search.GoogleSearchResultElement;

public class GoogleTest 
{
  public GoogleTest()
  {
  }

   public GoogleSearchResult doSearch(String queryString)
   {
    GoogleSearch search = new GoogleSearch();
    // Set mandatory attributes
    search.setKey("SET_YOUR_OWN_KEY");
    search.setQueryString(queryString);
    // Set optional attributes
    search.setSafeSearch(true);
    // Invoke the actual search
    try{
    GoogleSearchResult result = search.doSearch();
    return result;
    } catch (GoogleSearchFault e)
     {
       return null; 
     }
   }

   public void printResult(GoogleSearchResult result)
   {
    if (result != null)
    {
     GoogleSearchResultElement[] elements = (GoogleSearchResultElement[]) result.getResultElements();
     for (int i=0;i<elements.length;i++)
     {
      String title = elements[i].getTitle();
      String directoryTitle = elements[i].getDirectoryTitle();
      String snippet  = elements[i].getSnippet();
      
      System.out.print("======= Line#"+i+" ========");
      System.out.print("\n");
      System.out.print(title);
      System.out.print("\n");
      System.out.print(directoryTitle);
      System.out.print("\n");
      System.out.print(snippet);
      System.out.print("\n");
     }
    }else
    {
      System.out.print("no data found");
    }
   }

  public static void main(String[] args)
  {
    GoogleTest googleTest = new GoogleTest();
    GoogleSearchResult result = googleTest.doSearch("Rugby");
    googleTest.printResult(result);
  }
}
