retrofit文件上传和拦截器使用

来源：互联网发布：中文翻译意大利语软件编辑：程序博客网时间：2024/05/23 01:13

1.文件上传添加依赖

 compile 'com.squareup.retrofit2:retrofit:2.3.0'

自己的service

    @Multipart    @POST("you methd url upload/")    Call<ResponseBody> upload(@Part MultipartBody.Part file);

初始化retrofit

       retrofit = new Retrofit.Builder()                .client(builder.build())                //modify by zqikai 20160317 for 对http请求结果进行统一的预处理 GosnResponseBodyConvert//                .addConverterFactory(GsonConverterFactory.create())                //      .addConverterFactory(ResponseConvertFactory.create())                //    .addCallAdapterFactory(RxJavaCallAdapterFactory.create())                .baseUrl(BASE_URL)                .build();

   OkHttpClient.Builder builder = new OkHttpClient.Builder();        builder.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);

具体上传的方法

    public void retrofit(){        final File file = new File("/sdcard/mineicon.jpeg");        RequestBody requestFile =                RequestBody.create(MediaType.parse("multipart/form-data"), file);        MultipartBody.Part body =                MultipartBody.Part.createFormData("file", file.getName(), requestFile);     /*   RequestBody requestBody = new MultipartBody.Builder().setType(MultipartBody.FORM)                .addFormDataPart("file", "sss", RequestBody.create(MediaType.parse("image*//*"), bytes))                .build();*/             /*   RequestBody requestFile =                        RequestBody.create(MediaType.parse("multipart/form-data"),bytes);*/       Call<ResponseBody> call= HttpUtils.getInstance().getService().upload(body);        call.enqueue(new Callback<ResponseBody>() {            @Override            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {            }            @Override            public void onFailure(Call<ResponseBody> call, Throwable t) {            }        });    }

2.拦截器的使用

设置拦截级别

 HttpLoggingInterceptor.Level level= HttpLoggingInterceptor.Level.BASIC;

初始化拦截器

   HttpLoggingInterceptor loggingInterceptor=new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {            @Override            public void log(String message) {                Log.e("zcb","OkHttp====Message:"+message);            }        });

设置级别添加到okhttp

loggingInterceptor.setLevel(level);        builder.addInterceptor(loggingInterceptor);

添加到retrofit

  retrofit = new Retrofit.Builder()                .client(builder.build())

就能打印一些请求的url之类的了
