本文主要是介绍Retrofit2+OkHttp3+RxJava网络请求封装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
第一步： 添加依赖
//RxJava
implementation 'io.reactivex:rxjava:1.1.3'
//RxAndroid
implementation 'io.reactivex:rxandroid:1.1.0'
//retrofit
implementation 'com.squareup.retrofit2:retrofit:2.0.0'
//retrofit依赖Gson
implementation 'com.squareup.retrofit2:converter-gson:2.0.0'
//OkHttp
implementation 'com.squareup.okhttp3:okhttp:3.8.0'
//retrofit依赖RxJava
implementation 'com.squareup.retrofit2:adapter-rxjava:2.0.0'
//okhttp
implementation 'com.squareup.okhttp3:logging-interceptor:3.6.0'
//日志
implementation 'com.orhanobut:logger:2.2.0'
第二步：
RetrofitServiceManagerpackage com.example.myapplication;import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.orhanobut.logger.Logger;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.rxjava.RxJavaCallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;/*** Created by ShinnyYang on 2020/8/3.*/
public class RetrofitServiceManager {private static final int DEFAULT_CONNECT_TIME = 12;private static final int DEFAULT_WRITE_TIME = 12;private static final int DEFAULT_READ_TIME = 12;private static OkHttpClient okHttpClient;private static final String REQUEST_PATH = "http://admin.qianduoduo.cy6.co";private static Retrofit retrofit;private RetrofitServiceManager() {retrofit = new Retrofit.Builder().client(initOKHttp())//设置使用okhttp网络请求.baseUrl(REQUEST_PATH)//设置服务器路径.addConverterFactory(GsonConverterFactory.create())//添加转化库，默认是Gson.addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加回调库，采用RxJava.build();}public static OkHttpClient initOKHttp() {if (okHttpClient == null) {HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {@Overridepublic void log(String message) {//防止&、=都被转义Logger.e("okhttp==" + message);}});loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);okHttpClient = new OkHttpClient.Builder()/* .addInterceptor(new Interceptor() {@Overridepublic Response intercept(Chain chain) throws IOException {Request request = chain.request().newBuilder().addHeader("AuthToken", "").build();return chain.proceed(request);}})*/.connectTimeout(12, TimeUnit.SECONDS).readTimeout(12, TimeUnit.SECONDS).writeTimeout(12, TimeUnit.SECONDS).addInterceptor(loggingInterceptor).build();}return okHttpClient;}private static class SingletonHolder {private static final RetrofitServiceManager INSTANCE = new RetrofitServiceManager();}/** 获取RetrofitServiceManager**/public static RetrofitServiceManager getInstance() {return SingletonHolder.INSTANCE;}public <T> T create(Class<T> service) {return retrofit.create(service);}
}
第三步：
AllApi
package com.example.myapplication;import com.example.myapplication.bean.HomeListBean;import java.util.Map;import retrofit2.http.GET;
import retrofit2.http.Query;
import retrofit2.http.QueryMap;
import rx.Observable;/*** Created by ShinnyYang on 2020/8/3.*/
public interface AllApi {@GET("/qddapiv2/index/list.php")Observable<HomeListBean> getHomeList(@QueryMap Map<String, Object> map);
}
第四步：
HttpModel
package com.example.myapplication;import com.example.myapplication.bean.HomeListBean;import java.util.Map;import rx.Observable;
import rx.Observer;
import rx.android.schedulers.AndroidSchedulers;
import rx.schedulers.Schedulers;/*** Created by ShinnyYang on 2020/8/3.*/
public class HttpModel {private static AllApi movieService = RetrofitServiceManager.getInstance().create(AllApi.class);public static void getList(Map<String, Object> map,Observer<HomeListBean> observer) {setSubscribe(movieService.getHomeList(map), observer);}private static <T> void setSubscribe(Observable<T> observable, Observer<T> observer) {observable.subscribeOn(Schedulers.io()).subscribeOn(Schedulers.newThread())//子线程访问网络.observeOn(AndroidSchedulers.mainThread())//回调到主线程.subscribe(observer);}
}
第五步 ：
private void getData() {Map<String, Object> map = new HashMap<>();map.put("page", "1");map.put("auth", "");map.put("time", "1596091163");map.put("token", "ZcfveU5pHeYiqH6lfvE9qeIquMPVGnSloW7TYnryFCI=");map.put("uid", "0730096");map.put("action", "margin");map.put("device_no", "ece430f2-cda1-4c5c-be1e-a0657395470e");HttpModel.getList(map, new Observer<HomeListBean>() {@Overridepublic void onCompleted() {Toast.makeText(getApplicationContext(), "onCompleted", Toast.LENGTH_SHORT).show();}@Overridepublic void onError(Throwable e) {Logger.e("onError==>" + e.getMessage());}@Overridepublic void onNext(HomeListBean homeListBean) {Logger.e("onSuccess==>" + homeListBean.toString());}});
}
实体bean
package com.example.myapplication.bean;import java.util.List;public class HomeListBean {/*** status : 1* time : 1595819291* pagenum : 1* data : [{"task_id":"254","type_id":"11","thumb":"http://admin.qianduoduo.cy6.co/api/img/5.png","title":"999999999999999","unit_price":"400.00","num":"12","is_jingpin":"0","margin_per":1,"finish":2,"type_name":"微信转发","extra":"75"}]* msg : 查询成功*/private int status;private int time;private int pagenum;private String msg;private List<DataBean> data;public int getStatus() {return status;}public void setStatus(int status) {this.status = status;}public int getTime() {return time;}public void setTime(int time) {this.time = time;}public int getPagenum() {return pagenum;}public void setPagenum(int pagenum) {this.pagenum = pagenum;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public List<DataBean> getData() {return data;}public void setData(List<DataBean> data) {this.data = data;}@Overridepublic String toString() {return "HomeListBean{" +"status=" + status +", time=" + time +", pagenum=" + pagenum +", msg='" + msg + '\'' +", data=" + data +'}';}public static class DataBean {/*** task_id : 254* type_id : 11* thumb : http://admin.qianduoduo.cy6.co/api/img/5.png* title : 999999999999999* unit_price : 400.00* num : 12* is_jingpin : 0* margin_per : 1* finish : 2* type_name : 微信转发* extra : 75*/private String task_id;private String type_id;private String thumb;private String title;private String unit_price;private String num;private String is_jingpin;private int margin_per;private int finish;private String type_name;private String extra;@Overridepublic String toString() {return "DataBean{" +"task_id='" + task_id + '\'' +", type_id='" + type_id + '\'' +", thumb='" + thumb + '\'' +", title='" + title + '\'' +", unit_price='" + unit_price + '\'' +", num='" + num + '\'' +", is_jingpin='" + is_jingpin + '\'' +", margin_per=" + margin_per +", finish=" + finish +", type_name='" + type_name + '\'' +", extra='" + extra + '\'' +'}';}public String getTask_id() {return task_id;}public void setTask_id(String task_id) {this.task_id = task_id;}public String getType_id() {return type_id;}public void setType_id(String type_id) {this.type_id = type_id;}public String getThumb() {return thumb;}public void setThumb(String thumb) {this.thumb = thumb;}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public String getUnit_price() {return unit_price;}public void setUnit_price(String unit_price) {this.unit_price = unit_price;}public String getNum() {return num;}public void setNum(String num) {this.num = num;}public String getIs_jingpin() {return is_jingpin;}public void setIs_jingpin(String is_jingpin) {this.is_jingpin = is_jingpin;}public int getMargin_per() {return margin_per;}public void setMargin_per(int margin_per) {this.margin_per = margin_per;}public int getFinish() {return finish;}public void setFinish(int finish) {this.finish = finish;}public String getType_name() {return type_name;}public void setType_name(String type_name) {this.type_name = type_name;}public String getExtra() {return extra;}public void setExtra(String extra) {this.extra = extra;}}
}
完成！！！！！
常用的注解：
@GET GET请求方式
@POST POST请求方式
@Query GET请求参数
@Header用来添加Header请求头
@FormUrlEncoded post请求头标示 其他注解请求方式：
@PUT 表示这是一个PUT请求
@DELETE 表示这是一个DELETE请求
@HEAD 表示这是一个HEAD请求
@OPTIONS 表示这是一个OPTION请求
@PATCH 表示这是一个PAT请求
