Question

我正在使用Json简单库来处理twitter数据。然而根据一些json stansards，twitter数据无效。然后我转向Json智能库，但它显示了同样的问题。 Twitter数据具有键值对，使得该对可以包含许多双重投入的逗号，例如值=＆＃34;有些g＆＃34; uy＆＃34;。因此，这会导致违反json标准。即使某些值包含＆＃34; https：＆＃34;，冒号也会在解析时产生问题。请提出一些其他解析json的方法。

检查＆＃34;来源＆＃34;作为json的一个关键，例如上面定义的问题。提前完成。

使用的语言是java

代码是

package jsonParser;

import java.io.FileReader;
import java.util.Map;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Iterator;

import net.minidev.json.*;
import net.minidev.json.annotate.JsonIgnore;
import net.minidev.json.parser.*;



public class parse {
       public static void main(String[] args) throws FileNotFoundException, Exception, ParseException 
       {
           JSONParser parser = new JSONParser(JSONParser.ACCEPT_NON_QUOTE|JSONParser.ACCEPT_SIMPLE_QUOTE);
            Object ob= parser.parse(new FileReader("c:\\dailymotion2.3.json"));
            JSONObject jsonObject=(JSONObject)ob;
            JSONArray status=(JSONArray)jsonObject.get("statuses");
           for (Object o : status)
           {
             JSONObject person = (JSONObject) o;

             String text = (String) person.get("text");
             System.out.print(text);

            System.out.print("   ^^^   ");

             JSONObject entities= (JSONObject) person.get("entities");
             //System.out.println(city);
             JSONArray url=(JSONArray) entities.get("urls");

             for(Object c : url)
             {
                 JSONObject ob1=(JSONObject)c;
                 System.out.print((String)ob1.get("url")+" ");
             }

             System.out.print("   ^^^   ");


             JSONArray hash=(JSONArray)entities.get("hashtags");
             for(Object c : hash)
             {
                 JSONObject ob2=(JSONObject)c;
                 System.out.print((String)ob2.get("text")+" ");
             }

             System.out.println("");

           /*String job = (String) person.get("job");
             System.out.println(job);

             JSONArray cars = (JSONArray) person.get("cars");

             for (Object c : cars)
             {
               System.out.println(c+"");
             }*/

           }

       }
}

Answer 1

这不是有效的JSON，因为您可以在http://jsonlint.com/

进行验证

"source": "<a href="https-//mobile.twitter.com" rel="nofollow">Mobile Web (M2)</a>"

值字符串中有嵌套引号。
