[英]How do I parse this JSON object to get a list of recipe objects that I can then use?
所以我对 Java 非常陌生,需要帮助来解析 JSON 响应。 我已经有了我用来这样做的方法,但需要帮助弄清楚我到底做错了什么。
我正在使用 API 从站点检索食谱。 我正在尝试获取食谱列表(在这种情况下我假设为“命中”?),然后我可以向用户展示。
显然我需要配方名称(在这种情况下为“标签”)和其他信息。 谁能帮我?
这是我得到的响应 api 响应:

这是目前我用来解析 JSON object 的方法:
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
@Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
//JSONObject jsonData1 = new JSONObject(myResponse);
JSONObject Jobject = null;
try {
Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray Jarray = null;
try {
Jarray = Jobject.getJSONArray("hits");
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object;
try {
object = Jarray.getJSONObject(i);
try {
JSONArray Recipe = object.getJSONArray("recipe");
}catch (JSONException e){
e.printStackTrace();
}
for (int j = 0; j < Jarray.length(); j++){
JSONObject object2 = null;
try {
object2 = Jarray.getJSONObject(j);
String Name = object2.getString("label");
String Photo = object2.getString("image");
Log.d("rec_query", " " + Photo);
}catch (JSONException e){
e.printStackTrace();
Log.d("response6:", e.toString());
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
});
}
}
});
return null;
}
}
注意 {} {} 只是不同的配方...它不适合整个响应
目前,当我尝试在日志中打印我的变量时,我收到一条消息,指出变量为空(我用来存储不同配方/“命中”的变量。
您的回复似乎不完整,不是正确的 JSON 格式,提供正确的格式,我会尽力帮助您
String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
像这样,并且需要导入 com.alibaba.fastjson 但我不知道你是否可以使用 fastjson
