上载经过改造的文件时出现错误(无此文件或目录)

本文介绍了上载经过改造的文件时出现错误(无此文件或目录)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我正在使用android应用，因此我需要将请求和文件发布到服务器.我正在使用 retrofit 来执行此操作，并且我执行了 Multipart api请求.然后，我使用 Intent.createChooser 来选择文件.

I am working on android app and I need to post request with file to the server. I am using retrofit to do that and I do Multipart api request. Then I use Intent.createChooser to pick the file.

当我对服务调用进行入队时，就会出现问题.在 onFailure 中，我收到此错误:

The problem come in when I do enqueue to the service call. In the onFailure I get this error:

E/Upload errorrrrrr ::/document/image:77317(没有这样的文件或目录)

E/Upload errorrrrrr:: /document/image:77317 (No such file or directory)

但是，这是我在 onActivityResult 中获得的uri和文件路径:

However, This is the uri and file path which I get in the onActivityResult:

uri: content://com.android.providers.media.documents/document/image%3A77317

路径:/document/image:77317

然后我放权限:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera2.full" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <uses-feature android:name="android.hardware.camera.any" android:required="true" />

，这是请求:

@Multipart @POST("upload_document") Call<UploadDocuments> uploadDocuments( @Header("Authorization") String authorization, @Part MultipartBody.Part document_name, @Part("document_type") RequestBody document_type, @Part("fk_id") RequestBody fk_id, @Part("type") RequestBody type, @Part("certificate_name") RequestBody certificate_name, @Part("certificate_description") RequestBody certificate_description, @Part("notes") RequestBody notes);

我该如何解决这个问题?谢谢，

How I can solve this problem? and Thanks,

@Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_scan_passport); button = (Button) findViewById(R.id.btnUpload); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(); intent.setType("*/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent, "Select File"), PICK_PHOTO_FOR_AVATAR ); } }); } @Override protected void onActivityResult(int requestCode, final int resultCode, Intent data) { if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) { if (data == null) { //Display an error return; } else { Uri uri = data.getData(); path = data.getData().getPath(); if(uri != null) uploadFile(uri); } } super.onActivityResult(requestCode, resultCode, data); } private void uploadFile(Uri fileUri) { // use the FileUtils to get the actual file by uri File file = FileUtils.getFile( fileUri.getPath()); // create RequestBody instance from file final RequestBody requestFile = RequestBody.create( MediaType.parse("*/*"), file ); // MultipartBody.Part is used to send also the actual file name final MultipartBody.Part body = MultipartBody.Part.createFormData("document_name", file.getName(), requestFile); // add another part within the multipart request String document_type1 = "CV"; String fk_id1 ="2"; String type1 = "property_documents"; String certificate_name1 = "anyname"; String certificate_description1 = "anyDesc"; String notes1 = "anyNotes"; RequestBody document_type = RequestBody.create( okhttp3.MultipartBody.FORM, document_type1); RequestBody fk_id = RequestBody.create( okhttp3.MultipartBody.FORM, fk_id1); RequestBody type = RequestBody.create( okhttp3.MultipartBody.FORM, type1); RequestBody certificate_name = RequestBody.create( okhttp3.MultipartBody.FORM, certificate_name1); RequestBody certificate_description = RequestBody.create( okhttp3.MultipartBody.FORM, certificate_description1); RequestBody notes = RequestBody.create( okhttp3.MultipartBody.FORM, notes1); // finally, execute the request Call<UploadDocuments> call = service.uploadDocuments( authorization,body,document_type, fk_id,type,certificate_name, certificate_description,notes); call.enqueue(new Callback<UploadDocuments>() { @Override public void onResponse(Call<UploadDocuments> call,Response<UploadDocuments> response) { Log.v("Upload", "successssssssssss"); if(response.isSuccessful()) { String status = response.body().getMessage(); if (status.equals("success")) { String name = response.body().getData().getCertificateName(); Toast.makeText(getApplicationContext(),"done " + name,Toast.LENGTH_LONG).show(); } } } @Override public void onFailure(Call<UploadDocuments> call, Throwable t) { Log.e("Upload errorrrrrr:", t.getMessage()); } }); }

在将代码编辑为Jeel答案后，我还有其他问题，在拍摄图像时出现此错误:

Also I have additional problem after editing my code as Jeel answer, The problem when I take image capture I get this error:

我还设置了此提供程序:

推荐答案

您的问题是 API级别19 &在(Android Kitkat)上方，如果您为文件选择器打开文档提供程序，则 Uri 会根据您选择文件的位置而不同.

Your issue is that for API level 19 & above (Android Kitkat), if you open documents provider for your file picker then Uri you get back differs depending from where you pick file.

使用此类:

public class FileUtil { /* * Gets the file path of the given Uri. */ @SuppressLint("NewApi") public static String getPath(Uri uri, Context context) { final boolean needToCheckUri = Build.VERSION.SDK_INT >= 19; String selection = null; String[] selectionArgs = null; // Uri is different in versions after KITKAT (Android 4.4), we need to // deal with different Uris. if (needToCheckUri && DocumentsContract.isDocumentUri(context, uri)) { if (isExternalStorageDocument(uri)) { final String docId = DocumentsContract.getDocumentId(uri); final String[] split = docId.split(":"); return Environment.getExternalStorageDirectory() + "/" + split[1]; } else if (isDownloadsDocument(uri)) { final String id = DocumentsContract.getDocumentId(uri); if (id.startsWith("raw:")) { return id.replaceFirst("raw:", ""); } uri = ContentUris.withAppendedId( Uri.parse("content://downloads/public_downloads"), Long.valueOf(id)); } else if (isMediaDocument(uri)) { final String docId = DocumentsContract.getDocumentId(uri); final String[] split = docId.split(":"); final String type = split[0]; switch (type) { case "image": uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; break; case "video": uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI; break; case "audio": uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI; break; } selection = "_id=?"; selectionArgs = new String[]{ split[1] }; } } if ("content".equalsIgnoreCase(uri.getScheme())) { String[] projection = { MediaStore.Images.Media.DATA }; try (Cursor cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null)) { if (cursor != null && cursor.moveToFirst()) { int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); return cursor.getString(columnIndex); } } catch (Exception e) { Log.e("on getPath", "Exception", e); } } else if ("file".equalsIgnoreCase(uri.getScheme())) { return uri.getPath(); } return null; } /** * @param uri The Uri to check. * @return Whether the Uri authority is ExternalStorageProvider. */ private static boolean isExternalStorageDocument(Uri uri) { return "com.android.externalstorage.documents".equals(uri.getAuthority()); } /** * @param uri The Uri to check. * @return Whether the Uri authority is DownloadsProvider. */ private static boolean isDownloadsDocument(Uri uri) { return "com.android.providers.downloads.documents".equals(uri.getAuthority()); } /** * @param uri The Uri to check. * @return Whether the Uri authority is MediaProvider. */ private static boolean isMediaDocument(Uri uri) { return "com.android.providers.media.documents".equals(uri.getAuthority()); } }

并按照以下方式获取文件:

And obtain your file like below:

File file = new File(FileUtil.getPath(uri, this)); // *this* here is context, which can be Activity/Fragment

注意: 让我知道是否有人需要有关代码的说明.
