使用改造上传文件时出现错误（没有这样的文件或目录）
Getting error (No such file or directory) while uploading file with retrofit
我正在开发 android 应用程序，我需要 post 向服务器请求文件。
我正在使用 retrofit 来执行此操作，并且我会执行 Multipart api 请求。
然后我使用 Intent.createChooser 来选择文件。
当我 enqueue 调用服务时出现问题。在 onFailure 我得到这个错误：
E/Upload errorrrrrr:: /document/image:77317 (No such file or directory)
但是，这是我在 onActivityResult:
中得到的 uri 和文件路径
uri: content://com.android.providers.media.documents/document/image%3A77317
路径：/document/image:77317
然后我设置了权限：
<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？

}
您的问题是 API 级别 19 及以上 (Android Kitkat)，如果您为您的文件选择器打开文档提供程序，然后 Uri 您返回的结果因您选择文件的位置而异。
使用这个class:
public class FileUtil {

*/
@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;

uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;

selection = "_id=?";

}
if ("content".equalsIgnoreCase(uri.getScheme())) {

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;
}
/**

private static boolean isExternalStorageDocument(Uri uri) {
