我必须创建一个结构的json:
{
"user_id":"1",
"program_id":"2",
"test_id":["1","2","3","4"],
"answers":["a","c","d","b"]
}
我无法传递字符串数组,当我传递字符串数组时,它就像: -
{
"user_id":"1",
"program_id":"2",
"test_id":"[1,2,3,4]",
"answers":"[a,c,d,b]"
}
有人可以指导我如何使用上面所需的结构创建一个json吗?

我使用以下代码来实现它,ansAr
和qAr
是String arraylists:
JSONObject params = null;
JSONArray jsonAns = new JSONArray(ansAr);
JSONArray jsonQues = new JSONArray(qAr);
try {
params = new JSONObject();
params.put("userId", mSessionManager.getToken());
params.put("program_id", prgid);
params.put("test_id", jsonQues);
params.put("answer", jsonAns);
System.out.println("final params array" + params.toString());
} catch (Exception e) {
e.printStackTrace();
}
获取请求json如下:
{
"user_id":"1",
"program_id":"2",
"test_id":["1","2","3","4"],
"answers":["a","c","d","b"]
}

使用此..pattern创建json字符串数组..
String[] test_id = {"1", "2", "3", "4"};
JSONArray json = new JSONArray(Arrays.asList(data));
