本文介绍了一个使用Retrofit实现网络请求的实用工具类，包括单例模式的实现、OkHttp的日志拦截配置、以及如何通过自定义拦截器为所有POST请求添加公共参数。

public class RetyofitUitl {
private static  RetyofitUitl retyofitUitl;
    
     private RetyofitUitl(){
         
     }
    public static RetyofitUitl getRetyofitUitl (){
         if (retyofitUitl==null){
             synchronized (RetyofitUitl.class){
                 if (retyofitUitl==null){
                     retyofitUitl=new RetyofitUitl();
                 }
             }
         }
    }
    
    public  Resreivce  getPost(){

           //日志拦截 拦截器
        OkHttpClient okHttpClient = new OkHttpClient.Builder().addNetworkInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BASIC)).build();
        Retrofit retrofit=new Retrofit.Builder().baseUrl("https://www.zhaoapi.cn/")
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .client(okHttpClient)
                .build();
        Resreivce resreivce = retrofit.create(Resreivce.class);
        return  resreivce;
    }

 class MyInterceptor implements Interceptor {
     
     private FormBody.Builder formBody;
     private Request build1;

     @Override
     public Response intercept(Chain chain) throws IOException {
         Request request = chain.request();
         RequestBody body = request.body();
         if (body instanceof FormBody) {
             formBody = new FormBody.Builder();

             for (int i = 0; i < ((FormBody) body).
                     size(); i++) {
                 String name = ((FormBody) body).name(i);
                 String value = ((FormBody) body).value(i);
                 formBody.add(name, value);
             }
             formBody.add("token", "1");
             formBody.add("source", "android");
             formBody.add("appVersion", "101");
             FormBody build = formBody.build();
             build1 = request.newBuilder().post(build).build();

         }
         Response proceed = chain.proceed(build1);
         return proceed;
     }
 }
