上载经过改造的文件时出现错误(无此文件或目录) [英] Getting error (No such file or directory) while uploading file with retrofit
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，

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:

} else {

我还设置了此提供程序:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.provider"
android:exported="false"
android:grantUriPermissions="true"
tools:replace="android:authorities">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"
tools:replace="android:resource" />
</provider>
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.
