尝试使用改造将图像上传到服务器时出现以下错误,api收到标头授权令牌,_method =“put”和image =“imageName.jpg”作为参数,其他一切都是可选的,任何帮助将不胜感激。
java.io.FileNotFoundException:/storage/emulated/0/Download/space-wallpaper-21.jpg:open failed:EACCES(Permission denied)
userImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType("*/*");
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK && null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imageDecodableString = cursor.getString(columnIndex);
cursor.close();
StringBuilder stringBuilder = new StringBuilder(AUTHORIZATION);
sharedPreferences = this.getSharedPreferences(getResources().getString(R.string.token), 0);
stringBuilder.append(sharedPreferences.getString(getResources().getString(R.string.token), ""));
methodMap.put("_method", "PUT");
File file = new File(imageDecodableString);
RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestBody);
//RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "image");
Call<UserInfo> uploadImage = new RestClient(CONSTS.BASE_URL_ADDRESS_ACCOUNT_CREATION).getUserSignUpClient()
.postImage(stringBuilder.toString(), methodMap, body);
uploadImage.enqueue(new Callback<UserInfo>() {
@Override
public void onResponse(Call<UserInfo> call, Response<UserInfo> response) {
if (response.isSuccessful()) {
}
}
@Override
public void onFailure(Call<UserInfo> call, Throwable t) {
Toast.makeText(DetailActivity.this, t.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
接口:
public interface UserSignUpClient {
@POST("account")
Call<AuthenticationAccountCreationResponse> createAccount(@Body UserSignUp userSignUp);
@Multipart
@POST("account")
Call<UserInfo> postImage(@Header("Authorization") String headerValue, @PartMap Map<String, String> map, @Part MultipartBody.Part image);
}
改造构建器类:
public class RestClient {
private UserSignInClient userSignInClient;
private UserSignUpClient userSignUpClient;
private UserInfoClient userInfoClient;
private UserImageUploadClient userImageUploadClient;
public RestClient(String baseUrlLink){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrlLink)
.addConverterFactory(GsonConverterFactory.create()).build();
if (baseUrlLink.equals(CONSTS.BASE_URL_ADDRESS_TOKEN)){
userSignInClient = retrofit.create(UserSignInClient.class);
} else if (baseUrlLink.equals(CONSTS.BASE_URL_ADDRESS_ACCOUNT_CREATION)) {
userSignUpClient = retrofit.create(UserSignUpClient.class);
} else if (baseUrlLink.equals(CONSTS.BASE_URL_ADDRESS_USER_INFO)){
userInfoClient = retrofit.create(UserInfoClient.class);
}
}
public UserSignInClient getUserSignInClient() {
return userSignInClient;
}
public UserSignUpClient getUserSignUpClient() {
return userSignUpClient;
}
public UserInfoClient getUserInfoClient() {
return userInfoClient;
}
}

适用于Android 6.0 Marshmallow:
在Manifest中添加权限:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
适用于棉花糖及以上设备:
public class MainActivity extends AppCompatActivity implements ActivityCompat.OnRequestPermissionsResultCallback{
private static final int REQUEST_WRITE_PERMISSION = 786;
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == REQUEST_WRITE_PERMISSION && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
openFilePicker();//do your job
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestPermission();
}
private void requestPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_WRITE_PERMISSION);
} else {
openFilePicker();//do your job
}
}
}

注意:不要忘记在清单文件中添加权限
答案 1 :(得分:3)
添加此
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
在清单文件的清单标记内。但是确保它在应用程序标记之外。
