retrofit post请求上传表单和文件最重要的就是就是去构建RequestBody，今天为大家带来一种超级简单的上传方式
Body方式：
1、Retrofit接口RetrofitInterface
@POST(URLConstant.URL_PATH) Flowable<UploadImgBean> upload(@Body RequestBody Body);
2、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、构建body
public static Flowable<UploadImgBean> upload(List<File> fileList) {
//构建body
//addFormDataPart()第一个参数为表单名字，这是和后台约定好的
MultipartBody.Builder builder = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("username", "name")
.addFormDataPart("phone", "phone")
//注意，file是后台约定的参数，如果是多图，file[]，如果是单张图片，file就行
for (File file : fileList) {
//这里上传的是多图
builder.addFormDataPart("file[]", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));
}
RequestBody requestBody = builder.build();
return getRetrofitInterface(URLConstant.URL_BASE).upload(requestBody);
}
4、开始执行上传
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: ");
}
});
