rxjava+retrofit+okhttp

写一个接口等待实现,接口里面是请求方式

public interface ApiService {

@GET
Observable<String> get(@Url String url , @QueryMap Map<String,String> map);

@FormUrlEncoded
@POST
Observable<String> post(@Url String url, @FieldMap Map<String,String> map);

}

创建一个RetrofitManager

public class RetrofitManager {

public static OkHttpClient client = new OkHttpClient.Builder()
.build();

public static  ApiService  apiService = new Retrofit.Builder()
.baseUrl("http://120.27.23.105/")
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(ScalarsConverterFactory.create())
.client(cl
4000
ient)
.build()
.create(ApiService.class);

public static void get(String url, Map<String,String> map,Observer observer){

apiService.get(url,map)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(observer);

}

public static void post(String url,Map<String,String> map,Observer observer){
apiService.post(url,map)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(observer);
}

}

public abstract class BaseObserver<T> implements Observer<String> {

@Override
public void onSubscribe(Disposable d) {

}

@Override
public void onNext(String s) {

try {
Type genType = getClass().getGenericSuperclass();
Type[] params = ((ParameterizedType) genType).getActualTypeArguments();
Class entityClass = (Class) params[0];
Gson gson = new Gson();
T t = (T)gson.fromJson(s,entityClass);
success(t);

} catch (Exception e) {
failure(1001);
e.printStackTrace();
}

}

@Override
public void onError(Throwable e) {
try {
if(e != null){
if(e instanceof HttpException){
failure(HTTP_ERROR);
} else if(e instanceof SocketException){
failure(NET_WORK_ERROR);
}else {
failure(UNKNOW_ERROR);
}
}else {
failure(UNKNOW_ERROR);
}
e.printStackTrace() ;
} catch (Exception e1) {
failure(UNKNOW_ERROR);
e1.printStackTrace();
}

}

@Override
public void onComplete() {

}

//
