我正在使用Android Volley从API提取JSON对象。我将使用以下URL作为参考：https://glosbe.com/gapi/translate?from=la&dest=eng&format=json&phrase=puer&pretty=true
基本上，我正在尝试使用此API在拉丁语和英语之间进行转换。我遇到一个问题，当我在应用程序中获取JSON并使用toString()显示时，它没有显示某些内容，即使我在浏览器中将其提取，也无法看到。这是我的浏览器中的样子：

当我在应用程序中将其拉起时，它不会显示“短语”部分。这是我使用的代码：
RequestQueue mRequestQueue;
Cache cache = new DiskBasedCache(getActivity().getCacheDir(), 1024 * 1024); // 1MB cap
Network network = new BasicNetwork(new HurlStack());
mRequestQueue = new RequestQueue(cache, network);
mRequestQueue.start();
String url = "https://glosbe.com/gapi/translate?from=la&dest=eng&format=json&phrase=" + e.getText().toString();
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
(Request.Method.GET, url, null, new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response)
{
Log.d("JSON", response.toString());
try
{
JSONArray arr = response.getJSONArray("tuc");
try
{
JSONObject phrase = response.getJSONObject("phrase");
}
catch(JSONException e)
{
Toast.makeText(getActivity(), "Phrase not found", Toast.LENGTH_LONG).show();
}
Log.d("JSON", arr.toString());
try
{
JSONArray arr2 = arr.getJSONObject(0).getJSONArray("meanings");
definition = arr2.getJSONObject(0).getString("text");
t.setText(definition);
Toast.makeText(getActivity(), "Got stuff sucessfully", Toast.LENGTH_LONG).show();
}
catch (JSONException e)
{
JSONObject phrase = arr.getJSONObject(0);
definition = phrase.getString("text");
t.setText(definition);
Toast.makeText(getActivity(), "Got stuff succesfully with exception", Toast.LENGTH_LONG).show();
}
}
catch(JSONException e)
{
Log.d("error", e.toString());
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error)
{
Log.d("Error", error.toString());
}
});
MySingleton.getInstance(getActivity()).addToRequestQueue(jsonObjectRequest);
答案 0 :(得分：0)
您用来解析的代码与JSON的结构不匹配。
“ tuc”是一个数组，“短语”和“含义”在该数组的对象内部。假设您只想获得第一个短语：
Get-Content "appetest.txt" | Select-Object -Index (10,11,12,13,14,15,16,17,18,19,20) |set-content appetest10_new2.txt我认为是正确的，但目前我没有设置Android项目来对其进行测试。
答案 1 :(得分：0)
确定，这是在android中解析您的响应的代码：
try
{
JSONArray TUCarray = response.getJSONArray("tuc");
JsonObject phraseobject=TUCarray.getJSONObject(0).getJSONObject("phrase");
}
catch(JSONException e)
{
Toast.makeText(getActivity(), "Phrase not found",Toast.LENGTH_LONG).show();
}
在解析整个响应时要小心，因为我会看到TUC数组的某些对象没有子对象短语，例如：-您提供的链接的响应中TUC数组的最后一个对象）。
