【问题描述】：
我从 api 结构中获取数据时出现此错误。我检查了许多网站以供参考，但我没有得到正确的解决方案
public class ApiClient {
public static final String BASE_URL = "http://stock.adverscribe.in/api/controllers/";
private static Retrofit retrofit = null;
public
static Retrofit getClient() {
Gson gson = new GsonBuilder()
.setLenient()
.create();
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
}
return retrofit;
}
}
ApiInterface.java
public interface ApiInterface {
@GET("getMenu")
Call<MenuResponse> getMenuResult();
}
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<MenuResponse> call = apiService.getMenuResult();
call.enqueue(new Callback<MenuResponse>() {
@Override
public void onResponse(Call<MenuResponse> call, Response<MenuResponse> response) {
int code = response.body().getCode();
Toast.makeText(MainActivity.this, "" + code, Toast.LENGTH_SHORT).show();
}
@Override
public void onFailure(Call<MenuResponse> call, Throwable t) {
Toast.makeText(MainActivity.this, "" + t.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
}
这是json数据

【问题讨论】：
-
显示完整的错误堆栈跟踪。并显示您尝试解析的 JSON。
-
json 数据堆栈跟踪已添加到问题中，请查看
-
您提供的日志中没有异常堆栈跟踪。请给出异常堆栈跟踪。
-
正如@dave 提到的，除了 JSON 之外，您的 API 还会返回一些垃圾，这会使响应成为无效的 JSON。在继续之前让您的 API 返回 JSON。
