这个项目是mvp开发模式和retrofit+rxjava的开发框架
需要引入的jar包： implementation 'com.squareup.retrofit2:retrofit:2.1.0' implementation 'com.squareup.okhttp3:okhttp:3.5.0' implementation 'com.squareup.retrofit2:converter-gson:2.1.0' implementation 'io.reactivex.rxjava2:rxjava:2.0.1' implementation 'io.reactivex.rxjava2:rxandroid:2.0.1' implementation 'com.android.support:support-v4:28.0.0' implementation 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' implementation 'com.squareup.retrofit2:converter-scalars:2.3.0'
在retrofit这个文件夹中封装retrofit的网络请求框架
apiservice：定义请求方式
// 下面的是rxjava与retrofit的结合封装的apiservice
/** * TODO Get请求 */ @GET Observable getUser(@Url String url,@QueryMap Map<String, String> info); //简洁方式 直接获取所需数据
/**
* TODO POST请求
* @parmas url 请求地址
* @params Body 利用body进行参数封装
* @params headsMap 请求所需要的特殊请求头map<key,value>集合，如果有特殊的header，没有的话请传控map就可以
*/
@POST
//多个参数
Observable<BaseResponse> postUser(@Url String url, @Body RequestBody body, @HeaderMap Map<String,String>headsMap);
/**
* TODO DELETE
*/
@DELETE
Observable<BaseResponse> delete(@Url String url, @Body RequestBody body,@HeaderMap Map<String,String>headsMap);
/**
* TODO PUT
*/
@PUT()
@FormUrlEncoded
Observable<BaseResponse> put(@Url String url, @Body RequestBody body,@HeaderMap Map<String,String>headsMap);
/**
* TODO 文件上传
*/
//亲测可用
@Multipart
@POST
Observable<BaseResponse> uploadImage(@Url String url,@HeaderMap Map<String, String> headers, @Part MultipartBody.Part file);
/**
* 多文件上传
*/
@Multipart
@POST
Observable<BaseResponse> uploadImages(@Url String url,@HeaderMap Map<String, String> headers, @Part List<MultipartBody.Part> files);
/**
* 来自https://blog.csdn.net/impure/article/details/79658098
* @Streaming 这个注解必须添加，否则文件全部写入内存，文件过大会造成内存溢出
*/
@Streaming
@GET
Observable<BaseResponse> download(@Header("RANGE") String start, @Url String url);
2：LogInterceptor:定义的基本的网络请求拦截方式
3：RetrofitUtils:对网络请求进行实例化
