json 在 android 中使用改造时出现解析错误
json parsing error using retrofit in android
您好，我在解析过程中遇到问题 json。
我遇到了这个错误
D/MAgencyRepo: onFailure : java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
谷歌搜索此错误的结果表明我从 api 获得的响应与我制作的响应模型 class 不同。
所以我试图找到这两者之间的区别，但我找不到。
为什么会出现此错误？
我该如何解决？？
这是我的 class 代码，它是 DTO
public class ShortWeather implements Serializable {
@Expose
@SerializedName("response")
public Response response;
public static class Response implements Serializable{
@Expose

public Body body;
@Expose

@Override

这是我使用 retrofit
调用 api 的代码
MAgencyRepo class
public class MAgencyRepo {
private final String TAG = "MAgencyRepo";
private final static String BASE_URL = "http://apis.data.go.kr/1360000/VilageFcstInfoService_2.0/";
private static MAgencyRepo instance;
private Retrofit retrofit;
private MeteorologicalAgencyAPI MaAPI;
private ShortWeather sw;
public static MAgencyRepo getInStance() {
if(instance == null){
instance = new MAgencyRepo();
}
return instance;
}
public MutableLiveData<ShortWeather> getWeather() {
retrofit = new RetrofitService().getRetroInstance(BASE_URL);
MaAPI = retrofit.create(MeteorologicalAgencyAPI.class);
sw = new ShortWeather();
MutableLiveData<ShortWeather> data = new MutableLiveData<ShortWeather>();
callWeatherAPI(data);
return data;
}
private void callWeatherAPI(MutableLiveData<ShortWeather> data) {
Call<ShortWeather> call = MaAPI.getShortWeather("this is my api key",
50,1,"JSON","20210904","0500",55,127);
call.enqueue(new Callback<ShortWeather>() {
@Override
public void onResponse(Call<ShortWeather> call, Response<ShortWeather> response) {
if(response.isSuccessful()){
data.postValue(response.body());
Log.i(TAG,"API CONNECT SUCCESS");
Log.i(TAG,response.body().toString());
}else{
Log.i(TAG,"API CONNECT SUCCESS BUT WRONG PARAMETER");
Log.i(TAG,response.body().toString());
}
}
@Override
public void onFailure(Call<ShortWeather> call, Throwable t) {
Log.d(TAG,"onFailure : "+t.getMessage());
}
});
}
}
改装服务Class
public class RetrofitService {
public Retrofit getRetroInstance(String baseUrl){
Gson gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
}
我发现我放在代码中的 api 键被编码了。
但是当我尝试发送 api 密钥时，密钥又被编码了。
所以我一直收到一个错误说
服务密钥未注册
我不知道如何获取 http 连接日志。
所以我不知道发生了什么
但是我找到了一种使用 okhttp
从 http 连接获取日志的方法
这是我的代码
public class RetrofitService {
public Retrofit getRetroInstance(String baseUrl){
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl(baseUrl)
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
}
下次我应该使用 okhttp 来查看 http 连接日志。
您好，我在解析过程中遇到问题 json。

这是我使用 retrofit
调用 api 的代码MAgencyRepo class
public class MAgencyRepo {
private final String TAG = "MAgencyRepo";
private final static String BASE_URL = "http://apis.data.go.kr/1360000/VilageFcstInfoService_2.0/";
private static MAgencyRepo instance;
private Retrofit retrofit;
private MeteorologicalAgencyAPI MaAPI;
private ShortWeather sw;
public static MAgencyRepo getInStance() {
if(instance == null){
instance = new MAgencyRepo();
}
return instance;
}
public MutableLiveData<ShortWeather> getWeather() {
retrofit = new RetrofitService().getRetroInstance(BASE_URL);
MaAPI = retrofit.create(MeteorologicalAgencyAPI.class);
sw = new ShortWeather();
MutableLiveData<ShortWeather> data = new MutableLiveData<ShortWeather>();
callWeatherAPI(data);
return data;
}
private void callWeatherAPI(MutableLiveData<ShortWeather> data) {
Call<ShortWeather> call = MaAPI.getShortWeather("this is my api key",
50,1,"JSON","20210904","0500",55,127);
call.enqueue(new Callback<ShortWeather>() {
@Override
public void onResponse(Call<ShortWeather> call, Response<ShortWeather> response) {
if(response.isSuccessful()){
data.postValue(response.body());
Log.i(TAG,"API CONNECT SUCCESS");
Log.i(TAG,response.body().toString());
}else{
Log.i(TAG,"API CONNECT SUCCESS BUT WRONG PARAMETER");
Log.i(TAG,response.body().toString());
}
}
@Override
public void onFailure(Call<ShortWeather> call, Throwable t) {
Log.d(TAG,"onFailure : "+t.getMessage());
}
});
}
}
改装服务Class
public class RetrofitService {
public Retrofit getRetroInstance(String baseUrl){
Gson gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
}
我发现我放在代码中的 api 键被编码了。 但是当我尝试发送 api 密钥时，密钥又被编码了。 所以我一直收到一个错误说
服务密钥未注册
我不知道如何获取 http 连接日志。 所以我不知道发生了什么 但是我找到了一种使用 okhttp
从 http 连接获取日志的方法这是我的代码
public class RetrofitService {
public Retrofit getRetroInstance(String baseUrl){
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl(baseUrl)
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
}
下次我应该使用 okhttp 来查看 http 连接日志。
