傑克遜JSON解析器無效UTF-8起始字節

Question

我試圖解析以下JSON和我不斷收到一個JsonParseException：

{ 
    "episodes":{ 
     "description":"Episode 3 – Oprah's Surprise Patrol from 1\/20\/04\nTake a trip down memory lane and hear all your favorite episodes of The Oprah Winfrey Show from the last 25 seasons -- everyday on your radio!" 
    } 
} 

也對......未能在此JSON

{ 
    "episodes":{ 
     "description":"After 20 years in sports talk…he’s still the top dog! Catch Christopher 「Mad Dog」 Russo weekday afternoons on Mad Dog Radio as he tells it like it is…Give the Doggie a call at 888-623-3646." 
    } 
} 

例外：

org.codehaus.jackson.JsonParseException: Invalid UTF-8 start byte 0x96 
at [Source: C:\Json Test Files\episodes.txt; line: 3, column: 33] 
    at org.codehaus.jackson.JsonParser._constructError(JsonParser.java:1291)

    at com.niveus.jackson.Main.parseEpisodes(Main.java:37) 
    at com.niveus.jackson.Main.main(Main.java:13) 

代碼：

public class Main { 
    public static void main(String [] args) { 
     parseEpisodes("C:\\Json Test Files\\episodes.txt"); 
    } 
    public static void parseEpisodes(String filename) { 
     JsonFactory factory = new JsonFactory(); 
     JsonParser parser = null; 
     String nameField = null; 

     try { 
      parser = factory.createJsonParser(new File(filename)); 

      parser.configure(JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true); 
      parser.configure(JsonParser.Feature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER, true); 

      JsonToken token = parser.nextToken(); 
      nameField = parser.getText(); 
      String desc = null; 

      while (token != JsonToken.END_OBJECT) { 
       if (nameField.equals("episodes")) { 
        while (token != JsonToken.END_OBJECT) { 
         if (nameField.equals("description")) { 
          parser.nextToken(); 
          desc = parser.getText(); 
         } 

         token = parser.nextToken(); 
         nameField = parser.getText(); 
        } 
       } 

       token = parser.nextToken(); 
       nameField = parser.getText(); 
      } 

      System.out.println(desc); 
     } 
     catch (JsonParseException e) { 
      e.printStackTrace(); 
     } 
     catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
}

第33列的字符是–，而這將是字節0x96的原因是該文件物理編碼爲Windows-1252。您需要將文件保存爲UTF-8，windows-1252不是json的有效編碼。如何做到這一點取決於你使用的文本編輯器。

見JSON RFC：

1. 編碼

   JSON內容應以Unicode編碼。默認編碼是
   UTF-8。
