[英]Issue to Upload video file from android device to SpringBoot Rest API
I am stuck to achieve below functionality in android actually I dont have much working experience in android new APIs (API 29)我坚持在 android 中实现以下功能实际上我在 android 新 API(API 29)方面没有太多工作经验
1- Picked video from gallery, it gave me URI and I created IputeStreamRequestBody as per this thread 1- 从图库中挑选视频,它给了我 URI,我根据这个线程创建了 IputeStreamRequestBody
Here is my code for that:这是我的代码:
public class InputStreamRequestBody extends RequestBody {
private final MediaType contentType;
private final ContentResolver contentResolver;
private final Uri uri;
public InputStreamRequestBody(MediaType contentType, ContentResolver contentResolver, Uri uri) {
if (uri == null) throw new NullPointerException("uri == null");
this.contentType = contentType;
this.contentResolver = contentResolver;
this.uri = uri;
}
@Nullable
@Override
public MediaType contentType() {
return contentType;
}
@Override
public long contentLength() {
return -1;
}
@Override
public void writeTo(@NonNull BufferedSink sink) throws IOException {
try (Source source = Okio.source(contentResolver.openInputStream(uri))) {
sink.writeAll(source);
}
}
} }
Step: 3- Here is my retrofit code:步骤: 3- 这是我的 retrofit 代码:
public interface PlatformGroupPostService {
@Multipart
@POST("brainy/api/v0/post")
Observable<NewGroupAPIResponse> createPost(@Part("postData") RequestBody postData,
@Part MultipartBody.Part attachments);
} }
Request hit the server with null instance of file here is my Rest call:请求使用 null 文件实例到达服务器,这是我的 Rest 调用:
//attachments always coming null
public ResponseEntity<?> createPost(@RequestParam String postData,
@RequestPart(value = "attachments", required = false)
MultipartFile attachments) {
PostEntity postEntity = getPostEntity(postData);
return new ResponseEntity<>(postService.createPost(postEntity, attachments), HttpStatus.CREATED);
}
above rest API is working fine with PostMan request but from Retrofit call its not working.以上 rest API 在 PostMan 请求下工作正常,但来自 ZB9794896D699A785421Z2D376 的调用不工作。 I think I am doing something wrong.
我想我做错了什么。
I am struggling to achieve this feature since 4-5 days, applies multiple solution, Like自 4-5 天以来,我一直在努力实现此功能,应用多种解决方案,例如
1- store android file from gallery to cache and then tries to upload it, but same issue. 1-将 android 文件从画廊存储到缓存,然后尝试上传,但同样的问题。 Now kind of overflow for me
现在对我来说有点溢出
fun prepareFilePart(partName: String, uri: Uri, context: Context, name: String): MultipartBody.Part {
val inputStream = context.contentResolver.openInputStream(uri)
val file = File(context.cacheDir, name+".mp4")
val fos = FileOutputStream(file)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
if (inputStream != null) {
FileUtils.copy(inputStream, fos)
}
} else {
}
fos.flush();
fos.getFD().sync();
fos.close();
val requestBody: RequestBody =
RequestBody.create(MediaType.parse(context.contentResolver.getType(uri)), file)
return MultipartBody.Part.createFormData(partName, name, requestBody)
}
any help would be really appreciable任何帮助都会非常显着
Hi after long digging I found solution and its working now:嗨,经过长时间的挖掘,我找到了解决方案并且现在可以使用:
