问题描述

您好,我想从我的网站解析JSON。特jsonString我距离Te HTT presponse得到工作正常,但是当我试图解析它在的JSONObject它提供了NPE。
这与JSON IM测试现在:

  {galgjejson:
        {荷兰:
                            {length7:[
                                                {词:机器人},
                                                {词:露营},
                                                {词:koekjes}
                                            ]
                            },
                            {length8:[
                                                {词:机器人},
                                                {词:露营},
                                                {词:露营},
                                                {词:露营},
                                                {词:露营},
                                                {词:露营},
                                                {词:scheppen}
                                            ]
                            },
                            {length9:[
                                                {词:verslapen},
                                                {词:versleten},
                                                {词:verbrande}
                                            ]
                            },
                            {length10:[
                                                {词:verslapend},
                                                {词:versletend},
                                                {词:verbranden},
                                                {词:verbranden},
                                                {词:verbranden}
                                            ]
                            },
                            {length11:[
                                                {词:verslapende},
                                                {词:versletende}
                                            ]
                            },
                            {length12:[
                                                {词:verslapenden}
                                            ]
                            }
        },
        { 英语 :
                            {length7:[
                                                {词:毕业生},
                                                {词:街上购物},
                                                {词:烹饪}
                                            ]
                            },
                            {length8:[
                                                {词:停止},
                                                {词:沉睡},
                                                {词:开始},
                                                {词:开始},
                                                {词:开始},
                                                {词:开始},
                                                {词:开始}
                                        ]
                            },
                            {length9:[
                                                {词:somewordd},
                                                {词:somewordd},
                                                {词:somewordd}
                                            ]
                            },
                            {length10:[
                                                {词:someworddd},
                                                {词:someworddd}
                                            ]
                            },
                            {length11:[
                                                {词:somewordddd},
                                                {词:somewordddd},
                                                {词:somewordddd},
                                                {词:somewordddd},
                                                {词:somewordddd}
                                            ]
                            },
                            {length12:[
                                                {词:someworddddd},
                                                {词:someworddddd},
                                                {词:someworddddd}
                                            ]
                            }        }}

我做的方法:

 公共MikeyJSON(字符串jsonString){
    Log.i(JSON,jsonString:+ jsonString);
    尝试{
        JSONObject的myObject的=新的JSONObject(jsonString);
        Log.i(JSON,myObject_Object:+ myObject.toString());
    }赶上(JSONException E){
        // TODO自动生成catch块
        e.printStackTrace();
    }}公共字符串的getResult(郎字符串,字符串长度,诠释wordPos){
    串字=0;    尝试{
        langObject = myObject.getJSONObject(郎);
        Log.i(JSON,Language_Object+ langObject.toString());
        lengthObject = langObject.getJSONObject(长);
        Log.i(JSON,wordlength_Object+ lengthObject.toString());
        wordArray = lengthObject.getJSONArray(长);
        Log.i(JSON,wordlength_Object+ wordArray.toString());
        如果(wordPos> wordArray.length()){
            wordPos = 0;
        }
        对于(i = 0; I< wordArray.length();我++){
            字= wordArray.getJSONObject(wordPos)的ToString();
        }
        Log.i(JSON,word_Object+字);    }赶上(JSONException E){
        // TODO自动生成catch块
        e.printStackTrace();
    }    返回字;
}
}

我试图找回只有一个给定的语言和长度的字。这是我的很多研究后提出,但我只是不知道为什么它不会工作。如果我的JSON是无效的请求告诉我,我做错了什么,监守我得到这个错误之前NPE:

解决方案

您JSON是无效的 - 这是正确的格式:

  {荷兰:[
                        {length7:[
                                            {词:机器人},
                                            {词:露营},
                                            {词:koekjes}
                                        ]
                        },
                        {length8:[
                                            {词:机器人},
                                            {词:露营},
                                            {词:露营},
                                            {词:露营},
                                            {词:露营},
                                            {词:露营},
                                            {词:scheppen}
                                        ]
                        }]
}

目前,荷兰是一个JSONArray格式(它持有多个一个JSONObjects),但你的回答是缺少方括号。如果您解析荷兰作为JSONArray和一个删除长度一个JSONObjects之一,那么你应该能够使它工作

                                            ]
                            }

        }

}

The method I made:

    public MikeyJSON(String jsonString) {
    Log.i("JSON", "jsonString: " + jsonString);
    try {
        JSONObject myObject = new JSONObject(jsonString);
        Log.i("JSON", "myObject_Object: " + myObject.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

public String getResult(String lang, String length, int wordPos) {
    String word = "0";  

    try {
        langObject = myObject.getJSONObject(lang);
        Log.i("JSON", "Language_Object " + langObject.toString());
        lengthObject = langObject.getJSONObject(length);
        Log.i("JSON", "wordlength_Object " + lengthObject.toString());
        wordArray = lengthObject.getJSONArray(length);
        Log.i("JSON", "wordlength_Object " + wordArray.toString());
        if(wordPos>wordArray.length()) {
            wordPos = 0;
        }
        for(i=0;i<wordArray.length();i++){
            word = wordArray.getJSONObject(wordPos).toString();
        }
        Log.i("JSON", "word_Object " + word);

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return word;        
}
}

What I'm trying to retrieve is only one word of the given language and length. This is what I made after alot of research but i just don't get why it won't work. If my json is invalid pleas tell me what i'm doing wrong, becuase I get this error before the NPE:

解决方案

Your JSON is invalid - this is the correct format:

{ "Nederlands" :  [
                        { "length7" : [ 
                                            { "word" : "android" }, 
                                            { "word" : "camping" },
                                            { "word" : "koekjes" }
                                        ]
                        }, 
                        { "length8" : [
                                            { "word" : "androids" },    
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "campings" },
                                            { "word" : "scheppen" }
                                        ]
                        }]
}

At the moment, "Nederlands" is in the format of a JSONArray (it's holding multiple JSONObjects) but your response is missing the square brackets. If you parse "Nederlands" as a JSONArray and remove the "length" JSONObjects one by one then you should be able to make it work
