Android网络请求Retrofit进行二次封装,拿过来就能用

Android

Retrofit

import android.util.Log;

import java.util.concurrent.TimeUnit;

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;

/**

public class RetrofitUtils {
private static RetrofitUtils retrofitUtils;
private static Retrofit retrofit;
public RetrofitUtils() {
}

public static RetrofitUtils getInstance(){

if(retrofitUtils == null){
synchronized (RetrofitUtils.class){
if(retrofitUtils == null){
retrofitUtils = new RetrofitUtils();

}
}

}
return retrofitUtils;
}

public static synchronized Retrofit getRetrofit(String url){
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
@Override
public void log(String message) {
Log.i("xxx", "log: "+message);
}
});
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

OkHttpClient httpClient = new OkHttpClient.Builder().addInterceptor(httpLoggingInterceptor).connectTimeout(5000, TimeUnit.SECONDS).build();

if(retrofit == null){
retrofit = new Retrofit.Builder().baseUrl(url).client(httpClient).addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();

}
return retrofit;
}

public <T>T getApiService(String url,Class<T> cl){
Retrofit retrofit = getRetrofit(url);
return retrofit.create(cl);
}
}

这里用的时候需要写一个ApiService接口,用来写请求:

package com.bewei.retrofit.inter;import com.bewei.retrofit.bean.News;import com.bewei.retrofit.bean.Party;import com.bewei.retrofit.bean.User;import retrofit2.Call;import retrofit2.http.Field;import retrofit2.http.FormUrlEncoded;import retrofit2.http.GET;import retrofit2.http.POST;import retrofit2.http.Path;import retrofit2.http.Query;/** * 1. 类的用途 网络接口 * 2. @author forever * 3. @date 2017/11/1 14:32 */public interface ApiService {    /**     * 无参get请求     * http://service.meiyinkeqiu.com/service/ads/cptj      *     * @return     */    @GET("service/ads/cptj")    Call<News> getNoParams();    /**     * 有参get请求     * 拼接参数 /形式     *     * @return https://api.github.com/users/baiiu      */    @GET("users/{user}")   Call<User> getHasParams(@Path("user") String user);    /**     * http://www.93.gov.cn/93app/data.do      * channelId     * startNum     * 拼接 ? &     * 为主     */    @GET("data.do")   Call<Party> getHasParams2(@Query("channelId")int channelId, @Query("startNum") int startNum );    /**     * post请求 http://120.27.23.105/user/reg 注册     */    @POST("reg")    @FormUrlEncoded//支持表单提交    Call<User> register(@Field("mobile")String mobile,@Field("password")String password);}

这里边列出了各种方式的网络请求,

这样,就可以使用Retrofit了
