【问题】当同一个接口需要同时上传多张图片，多个语音文件，还有其他普通类型的参数。得 怎处理网络层和View层代码？
【法1】
(1) 网络层：
【代码】
public void upload(Map partMap) {
TempService service = RetrofitServiceManager.getInstance().create(TempService.class);
observe(service.commitReply(partMap), new Observer() {
@Override
public void onCompleted() { // todo }
@Override
public void onError(Throwable e) { // todo }
@Override
public void onNext(BaseResponse response) { // todo }
});
}
（2） View层 ：
【代码】
Map partMap = new HashMap<>();
if(mFilePath != null) { //有上传语音文件
audioFile=newFile(mFilePath);
RequestBody fileBody = RequestBody.create(MediaType.parse("audio/*"),audioFile);
partMap.put("voice\";filename=\""+audioFile.getName()+"",fileBody);
}
if( images != null && images.size() !=0 ) { //有上传图片
for(inti =0 ;i< images.size(); i++){
String path =images.get(i).path;
imagePaths.add(newFile(path));
} }
for(File file :imagePaths){
RequestBody fileBody = RequestBody.create(MediaType.parse("image/*"),file);
partMap.put("pic\";filename=\""+ file.getName()+"",fileBody);
}
partMap.put("accessToken",RequestBody.create(null,"tTrLgDBA2lxdsHJOAZu9Sw=="));
partMap.put("memberId",RequestBody.create(null,"3"));
partMap.put("hotReply.problemId",RequestBody.create(null,mProblemId+""));
partMap.put("hotReply.content",RequestBody.create(null,mAnswerText));
partMap.put("hotReply.voiceDuration",RequestBody.create(null,mRecordTime+""));
mPresenter.upload(partMap) ; // 提交专家回答信息
