JSON轉換結果在Java失敗（JSONObject無法轉換爲JSONArray）

我的PHP腳本的JSON結果有問題。我無法在JAVA中提取此結果。下面有錯誤：JSON轉換結果在Java失敗（JSONObject無法轉換爲JSONArray）

Error converting result org.json.JSONException: Value 
{"3":[{"date":"25\/07\/2011","descr":"Une colloque bla bla","numColloque":"1","titre":"Une colloque"}],

     {"numPublication":"3","lienPDF":"http:\/\/www.irdes.com","date":"25\/07\/2011","numTypePublication":"3","titre":"un titre"}]} 

of type org.json.JSONObject cannot be converted to JSONArray

我結果的語法很簡單：

{"Object1":[{"id":"value"},{"id":"value"}], 
"Object2":[{"id":"value"},{"id":"value"}], 
... 
}

我對提取JAVA腳本（LIGNE錯誤：有**）：

result=sb.toString(); 
**JSONArray jArray = new JSONArray(result);** 
for (int i=1;i<=9;i++){ 
    JSONObject typeUpdateObject = jArray.getJSONObject(i); 
    extraction(typeUpdateObject, i); 
}

這不是這種提取的正確方法嗎？

由克里斯和查爾斯的答案是正確的，你應該看看在JSON specification。也就是說，我相信以下是你正在尋找的。

JSONObject obj = new JSONObject(result); 
for(int i=1;i<=9;i++) { 
    JSONArray arr = obj.getJSONArray(""+i); 
    for(int j=0;j<arr.length();j++) 
     extraction(arr.getJSONObject(j), i); 
}

感謝您的代碼馬特:)只是爲第二個，它是j變量:)（j toshiro92

感謝您的區別！ –

您在對象和數組之間感到困惑。

你發佈的代碼示例都是對象{}而數組是[]。

你擁有的結構是：{[{}]}

而您解析代碼片斷期待：[{}]

有錯誤一大提示：類型org.json.JSONObject不能轉換到JSONArray

一個對象是key：value對的無序列表。

{ // object 
    "key" : "value", 
    "key2" : "another value" 
}

數組是值的有序（索引）列表：

[ // array 
    "value1", 
    "value2" 
]

我明白，但我的PHP代碼編碼一個數組，對象數組值。感謝您的解釋。 – toshiro92

{ 
    "glossary": { 
     "title": "example glossary", 
     "GlossDiv": { 
      "title": "S", 
      "GlossList": { 
       "GlossEntry": { 
        "ID": "SGML", 
        "SortAs": "SGML", 
        "GlossTerm": "Standard Generalized Markup Language", 
        "Acronym": "SGML", 
        "Abbrev": "ISO 8879:1986", 
        "GlossDef": { 
         "para": "A meta-markup language, used to create markup languages such as DocBook.", 
         "GlossSeeAlso": ["GML", "XML"] 
        }, 
        "GlossSee": "markup" 
       } 
      } 
     } 
    } 
}

這是一個JSON應該如何看，

查爾斯所述對象{}陣列[] ，這是一個方便的學習JSON的備忘單

object {} {成員} 構件對對，成員對字符串：值陣列 [] [元素] 元件值值，元件值字符串號碼對象陣列真假空
