Plurk API 兩三事-json-simple

千呼萬換後...Plurk的官方API終於出來了(http://www.plurk.com/API)
目前支援Java以及Python,其他語言可能要找些地下版的
目前簡單的撰寫了個小bot測試,簡單紀錄一下
由於plurk使用了json此資料格式,所以資料格式其實很早就被推測導致非官方API大量出現
而在這兩天的測試要parse json data時,java有非常多的json的library,簡單的找了星塵
提供的Java Plurk API中使用的json-simple(A simple Java toolkit for JSON) 此library
下載http://code.google.com/p/json-simple/downloads/list
下面是我參考的decode部分
http://code.google.com/p/json-simple/wiki/DecodingExamples
我選擇了實做一個簡單的KeyFinder,source code如下:

import java.io.IOException;
import org.json.simple.parser.ContentHandler;
import org.json.simple.parser.ParseException;


/**

class KeyFinder implements ContentHandler{
  private Object value;
  private boolean found = false;
  private boolean end = false;
  private String key;
  private String matchKey;

  public void setMatchKey(String matchKey){
    this.matchKey = matchKey;
  }

  public Object getValue(){
    return value;
  }

  public boolean isEnd(){
    return end;
  }

  public void setFound(boolean found){
    this.found = found;
  }

  public boolean isFound(){
    return found;
  }

  public void startJSON() throws ParseException, IOException {
    found = false;
    end = false;
  }

  public void endJSON() throws ParseException, IOException {
    end = true;
  }

  public boolean primitive(Object value) throws ParseException, IOException {
    if(key != null){
      if(key.equals(matchKey)){
        found = true;
        this.value = value;
        key = null;
        return false;
      }
    }
    return true;
  }

  public boolean startArray() throws ParseException, IOException {
    return true;
  }


  public boolean startObject() throws ParseException, IOException {
    return true;
  }

  public boolean startObjectEntry(String key) throws ParseException, IOException {
    this.key = key;
    return true;
  }

  public boolean endArray() throws ParseException, IOException {
    return false;
  }

  public boolean endObject() throws ParseException, IOException {
    return true;
  }

  public boolean endObjectEntry() throws ParseException, IOException {
    return true;
  }
}

搭配上此key finder就可以任意找出自己要的key的對應值了
