简单封装retrofit2+rxjava2

1,添加依赖

compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.okhttp3:okhttp:3.3.1'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
//适配器
compile 'com.squareup.okhttp3:logging-interceptor:3.8.1'
compile "com.squareup.retrofit2:adapter-rxjava2:2.2.0"
compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'

2,配置okhttp和retrofit

package com.weijie.aiboy.base;

import android.util.Log;

import com.google.gson.FieldNamingPolicy;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.weijie.aiboy.api.ServiceAPI;

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import okhttp3.Interceptor;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;

public class BaseRetrofit {

    private static final String BASE_URL = "http://101.37.34.109:8080/lol/";

    private static final long TIMEOUT = 30;

    // Retrofit是基于OkHttpClient的，可以创建一个OkHttpClient进行一些配置
    private static OkHttpClient httpClient = new OkHttpClient.Builder()
            // 添加通用的Header
            .addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request.Builder builder = chain.request().newBuilder();
                    return chain.proceed(builder.build());
                }
            })
            /*
            这里可以添加一个HttpLoggingInterceptor，因为Retrofit封装好了从Http请求到解析，
            出了bug很难找出来问题，添加HttpLoggingInterceptor拦截器方便调试接口
             */
            .addInterceptor(new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
                @Override
                public void log(String message) {
                    Log.i("----->",message);
                }
            }).setLevel(HttpLoggingInterceptor.Level.BASIC))
            .connectTimeout(TIMEOUT, TimeUnit.SECONDS)
            .readTimeout(TIMEOUT, TimeUnit.SECONDS)
            .build();

    private static ServiceAPI retrofitService = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            // 添加Gson转换器
            .addConverterFactory(GsonConverterFactory.create(buildGson()))
            // 添加Retrofit到RxJava的转换器
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .client(httpClient)
            .build()
            .create(ServiceAPI.class);

    public static ServiceAPI getInstance() {
        return retrofitService;
    }

    private static Gson buildGson() {
        return new GsonBuilder()
                .serializeNulls()
                .setFieldNamingPolicy(FieldNamingPolicy.IDENTITY)
                .create();
    }
}

3,定义接口文件

package com.weijie.aiboy.api;


import com.weijie.aiboy.bean.ShouyeBeen;

import java.util.Map;

import io.reactivex.Observable;
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import retrofit2.Response;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;
import retrofit2.http.QueryMap;

/**
 * Created by Administrator on 2017/8/12.
 */

public interface ServiceAPI {
   /*post上传*/
    @POST("game/getHome")
    Observable>getShouyeInfo(@QueryMap Map map);
    /*图文上传*/
    @Multipart
    @POST("user/updateUserImg")
    Observable>upDateHeadImg(@Part("userId")RequestBody body, @Part MultipartBody.Part file);
}

4，定义baseObsever

package com.weijie.aiboy.base;

import android.content.Context;
import android.util.Log;
import android.widget.Toast;

import io.reactivex.Observer;
import io.reactivex.disposables.Disposable;
import retrofit2.Response;

public abstract class BaseObserver implements Observer> {

    private static final String TAG = "BaseObserver";
    private Context mContext;

    protected BaseObserver(Context context) {
        this.mContext = context.getApplicationContext();
    }

    @Override
    public void onSubscribe(Disposable d) {

    }

    @Override
    public void onNext(Response value) {
        if (value != null) {
            if (value.isSuccessful()) {
                T t = value.body();
                onHandleSuccess(t);
            } else {
                onHandleError(value.message());
            }
        }
    }

    @Override
    public void onError(Throwable e) {
        Log.e(TAG, "error:" + e.toString());
    }

    @Override
    public void onComplete() {
        Log.d(TAG, "onComplete");
    }


    protected abstract void onHandleSuccess(T t);

    protected void onHandleError(String msg) {
        Toast.makeText(mContext, msg, Toast.LENGTH_SHORT).show();
    }
}

5,定义BaseEntity

package com.weijie.aiboy.entity;

import com.google.gson.annotations.SerializedName;

public class BaseEntity {

    @SerializedName("state")
    private int state;
    @SerializedName("msg")
    private String msg;
    @SerializedName("data")
    private E AdsList;

    public boolean isSuccess() {
        return state == 0;
    }

    public int getState() {
        return state;
    }

    public void setState(int code) {
        this.state = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public E getAdsList() {
        return AdsList;
    }

    public void setAdsList(E AdsList) {
        this.AdsList = AdsList;
    }
}

6，封装线程切换

package com.weijie.aiboy.base;

import io.reactivex.Observable;
import io.reactivex.ObservableSource;
import io.reactivex.ObservableTransformer;
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.Disposable;
import io.reactivex.functions.Consumer;
import io.reactivex.schedulers.Schedulers;

public class MyRxSchedulers {

    public static  ObservableTransformer compose() {
        return new ObservableTransformer() {
            @Override
            public ObservableSource apply(Observable observable) {
                return observable
                        .subscribeOn(Schedulers.io())
                        .doOnSubscribe(new Consumer() {
                            @Override
                            public void accept(Disposable disposable) throws Exception {
//                                if (!Utils.isNetworkConnected()) {
//                                    Toast.makeText(context, R.string.toast_network_error, Toast.LENGTH_SHORT).show();
//                                }
                            }
                        })
                        .observeOn(AndroidSchedulers.mainThread());
            }
        };
    }
}

其他

package com.weijie.aiboy.base;

import okhttp3.MediaType;
import okhttp3.RequestBody;

/**
 * Created by Administrator on 2017/8/15.
 */

public class RetrofitUtils {
    /*图文上传转默认文本格式*/
    public static RequestBody exchangeTextType(String s){
       RequestBody body= RequestBody.create(MediaType.parse("text/plain"),s);
        return body;
    }
}

*示例

 final File file=new File(Environment.getExternalStorageDirectory() + "/head.jpg");
        Log.d("ppppppp",file.length()+"");
        MediaType MEDIATYPE = MediaType.parse(judgeType(Environment.getExternalStorageDirectory() + "/head.jpg"));
        RequestBody requestFile = RequestBody.create(MEDIATYPE, file);
        HashMapmap=new HashMap<>();
        MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);
        map.put("userId",RequestBody.create(MediaType.parse("text/plain"),"33"));

        BaseRetrofit.getInstance().upDateHeadImg(RetrofitUtils.exchangeTextType("33"),body).compose(MyRxSchedulers.>compose()).subscribe(new Consumer>() {
            @Override
            public void accept(Response
