我的服务器发送如下数据。我正在使用Gson来解析这些数据。但它失败了以下例外：
{
"users":[
{
"config":{
"identifiers":{
"id":"7"
},
"v_id":[
"335",
"Product User "
],
"m_id":[
"3530",
"4744"
],
"expand":{
"chategory":[
{
"identifiers":{
"id":"3"
},
"catConfig":{
"security":"Private"
}
}
],
"hobby":[
{
"identifiers":{
"id":"200",
"d_id":[
"Playing \"Football\"",
"Music",
"Dancing",
"Browsing"
]
},
"type":"Output"
}
]
}
}
}
]
}
异常

注意输入带有转义序列，其中Gson抱怨字符串没有它。此外，如果它是一个普通的JsonObject而不是JsonArray，它的工作正常。
可能是什么问题？

我提取了你的json部分
{"d_id":["Playing \"Football\"","Music","Dancing","Browsing"]}
我试图将你的json复制到Pojo类中并生成以下类
public class Bean {
private String[] d_id;
public String[] getD_id() {
return d_id;
}
public void setD_id(String[] d_id) {
this.d_id = d_id;
}
@Override
public String toString() {
return "ClassPojo [d_id = " + d_id + "]";
}
}
RetrofitUtil
public class UtilRetrofit {
public static String URL = "";
private static ENDPointerListener sENDPointerListener;
public static ENDPointerListener getENDPointerListener() {
if (sENDPointerListener == null) {
sENDPointerListener = new ENDPointerListener() {
@Override
public String getEndPoint() {
return URL;
}
};
}
return sENDPointerListener;
}
public static void setENDPointerListener(ENDPointerListener pENDPointerListener) {
sENDPointerListener = pENDPointerListener;
}
public interface ENDPointerListener {
String getEndPoint();
}
public static <T> T build(Class<T> t) {
OkHttpClient okhttp = new OkHttpClient.Builder().addInterceptor(new StethoInterceptor()).build();
Retrofit retrofit = new Retrofit.Builder().client(okhttp)
.baseUrl(getENDPointerListener().getEndPoint())
.addConverterFactory(GsonConverterFactory.create(new GsonBuilder()
.setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")
.create()))
.build();
return retrofit.create(t);
}
}
使用Retrofit和mock服务器来检索值
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
RestA rest = UtilRetrofit.build(RestA.class);
Call<Bean> call = rest.geBean();
call.enqueue(new Callback<Bean>() {
@Override
public void onResponse(Call<Bean> call, Response<Bean> response) {
Bean data =response.body();
}
@Override
public void onFailure(Call<Bean> call, Throwable t) {
Toast.makeText(getActivity(),t.toString(),Toast.LENGTH_SHORT).show();
}
});
}
即使字符串中有双引号，我的结果也很好。你的bean类有什么问题吗？
@RunWith(AndroidJUnit4.class)
@SmallTest
public class RestATest {
@Rule
public ActivityTestRule<MainActivity> mMainActivityActivityTestRule = new ActivityTestRule<MainActivity>(MainActivity.class, true, false);
private MockWebServer mMock;
@Before
public void set() {
mMock = new MockWebServer();
try {
mMock.play();
} catch (IOException pE) {
pE.printStackTrace();
}
//set the mock Server
UtilRetrofit.URL = mMock.getUrl("/").toString();
}
@Test
public void testRequest1() {
String bodyStr = "{\"d_id\":[\n\"Playing \\\"Football\\\"\",\n\"Music\",\n\"Dancing\",\n\"Browsing\"\n]\n}";
mMock.enqueue(new MockResponse().setResponseCode(200).setBody(bodyStr));
mMainActivityActivityTestRule.launchActivity(null);
}
}

我尝试使用GSON默认的Deserializer并且工作正常。我没有任何例外。
private void parseJSON() {
String json = "{\"users\":[{\"config\":{\"identifiers\":{\"id\":\"7\"},\"v_id\":[\"335\",\"Product User \"],\"m_id\":[\"3530\",\"4744\"],\"expand\":{\"chategory\":[{\"identifiers\":{\"id\":\"3\"},\"catConfig\":{\"security\":\"Private\"}}],\"hobby\":[{\"identifiers\":{\"id\":\"200\",\"d_id\":[\"Playing \\\"Football\\\"\",\"Music\",\"Dancing\",\"Browsing\"]},\"type\":\"Output\"}]}}}]}";
Gson gson = new Gson();
JSONResponse jsonResponse = gson.fromJson(json, JSONResponse.class);
for (String s : jsonResponse.getUsers().get(0).getConfig().getExpand().getHobby().get(0).getIdentifiers().getDId()) {
System.out.println(s);
}
}
输出：
08-19 12:26:49.682 12405-12405/com.trial.mobileapps.gsontrial I/System.out: Playing "Football"
08-19 12:26:49.682 12405-12405/com.trial.mobileapps.gsontrial I/System.out: Music
