retrofit post請(qǐng)求上傳表單和文件最重要的就是就是去構(gòu)建RequestBody仅炊，今天為大家?guī)?lái)一種超級(jí)簡(jiǎn)單的上傳方式
Body方式：
1、Retrofit接口RetrofitInterface
@POST(URLConstant.URL_PATH)
Flowable<UploadImgBean> upload(@Body RequestBody Body);
2蜕窿、Retrofit的配置
private static RetrofitInterface getRetrofitInterface(String baseUrl) {
if (retrofitInterface == null) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create())
// .addConverterFactory(ScalarsConverterFactory.create()) //string
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
retrofitInterface = retrofit.create(RetrofitInterface.class);
}
return retrofitInterface;
}
3、構(gòu)建body
public static Flowable<UploadImgBean> upload(List<File> fileList) {
//構(gòu)建body
//addFormDataPart()第一個(gè)參數(shù)為表單名字桐经，這是和后臺(tái)約定好的
MultipartBody.Builder builder = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("username", "name")
.addFormDataPart("phone", "phone")
//注意，file是后臺(tái)約定的參數(shù)气堕，如果是多圖畔咧，file[]，如果是單張圖片誓沸，file就行
for (File file : fileList) {
//這里上傳的是多圖
builder.addFormDataPart("file[]", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));
}
RequestBody requestBody = builder.build();
return getRetrofitInterface(URLConstant.URL_BASE).upload(requestBody);
}
4蔽介、開始執(zhí)行上傳
HttpUtils.upload(mUploadFileList)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new DisposableSubscriber<UploadImgBean>() {
@Override
public void onNext(UploadImgBean uploadImgBean) {
Log.i(TAG, "onNext: " );
}
}
@Override
public void onError(Throwable throwable) {
Log.i(TAG, "onError: --->" + throwable.getMessage());
}
@Override
public void onComplete() {
Log.i(TAG, "onComplete: ");
}
});
