分析:post请求,图片的上传是以文件形式的byte\[\]上传的.----服务器要求以表单形式上传

### Retrofit实战: ###

如何选择对应的Api接口呢?

1.  需要文件上传
2.  带参数

官方文档说明:用@Multipart形式的post

public interface UserApi{
     /**
         * 修改用户信息api接口
         * @param id
         * @param username
         * @param sex
         * @param email
         * @return
         */
        @Multipart
        @POST("UserHandler.ashx/user/personal/update")
        Call<Response<User>> updataUserInfo( @Part MultipartBody.Part id,
                                             @Part MultipartBody.Part username,
                                             @Part MultipartBody.Part sex,
                                             @Part MultipartBody.Part email,
                                             @Part MultipartBody.Part file
                                             );
    
    }

配置Api接口:

public class ApiRetrofit { 
        public UserApi userApiService;
        public static final String USER_BASE_URL = "http://lxqmainserv01.chinacloudapp.cn/projects/tulou/communication/user/";
      ApiRetrofit() {
            Retrofit retrofit_user = new Retrofit.Builder()
                    .baseUrl(USER_BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .build();
            userApiService = retrofit_user.create(UserApi.class);
     }
    }

建立获取单例模式,得到配置好的单例接口继承对象 UserApi :

public class ApiFactory {
    
        protected static final Object monitor = new Object();
        static UserApi userApiSingleton = null;
    
    
        //return Singleton
        public static UserApi getUserApiSingleton() {
            synchronized (monitor) {
                if (userApiSingleton == null) {
                    userApiSingleton = new ApiRetrofit().getUserApiService();
                }
                return userApiSingleton;
            }
        }
    }

到这里retrofit的文件终于完成,现在开始使用:

public void upLoadInfo(final View view) {
            DialogUtils.showCustomDialogFragment(mActivity);
            UserApi userApiSingleton = ApiFactory.getUserApiSingleton();
            final File file = new File(path+"image.png");
            MultipartBody.Part id =
                    MultipartBody.Part.createFormData("id", user_id+"");
            MultipartBody.Part name =
                    MultipartBody.Part.createFormData("username", username+"");
            MultipartBody.Part sex1 =
                    MultipartBody.Part.createFormData("sex", sex+"");
            MultipartBody.Part user_email =
                    MultipartBody.Part.createFormData("email", email+"");
            RequestBody image =
                    RequestBody.create(MediaType.parse("multipart/form-data"), file);
            MultipartBody.Part photo1part =
                    MultipartBody.Part.createFormData("avatarimage", file.getName(),image);
            Call<Response<User>> call = userApiSingleton.updataUserInfo(id, name, sex1, user_email,photo1part);
            call.enqueue(new Callback<Response<User>>() {
                @Override
                public void onResponse(Call<Response<User>> call, retrofit2.Response<Response<User>> response) {
                    User data = response.body().getData();
                    App.savePreUser(data);
                    DialogUtils.dismissProgress();
                    finish();
                    //Log.i(TAG, "onResponse: 成功了");
                }
    
                @Override
                public void onFailure(Call<Response<User>> call, Throwable t) {
                    DialogUtils.dismissProgress();
                    TopSnackbarUtil.showTopBar(view, "保存失败,请重试");
                    Log.i(TAG, "onFailure: "+t.toString());
                }
            });
    
    
        }
