使用 retrofit2 上传文件 - 文件正在上传，但响应"onFailure"

Question

我需要上传一个图像作为文件，已经尝试了堆栈中的不同解决方案，但我仍然坚持。有人能向我解释我做错了什么吗？

上传功能

private void EnviarFotos(){
iGeoPBService geoPBService = GeoPBService.getInstance().usarServico();
List<Foto> listaFotos = bancoDadosController.syncFotos();
for (final Foto foto : listaFotos){
String numObra = foto.getNumeroObra();
String idAcomp = foto.getIdAcompanhamento();
String idMedicao = foto.getIdMedicao();
String imagem = foto.getImagem();
final File file = FileFoto(imagem);
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"),file);
MultipartBody.Part multipartBody = MultipartBody.Part.createFormData("file",foto.getNomeFoto(),requestFile);
if (idAcomp.equals("N/A")){
Call<String> envioMed = geoPBService.uploadFotoMedicao(idJurisdicionado,numObra,idMedicao,multipartBody);
envioMed.enqueue(new Callback<String>() {
@Override
public void onResponse(Call<String> call, Response<String> response) {
if (response.isSuccessful()){
bancoDadosController.atualizaStatusSyncFoto(foto.getNomeFoto());
AttInfos();
Log.d("TESTE","FOTO ENVIADA COM SUCESSO!!!");
file.delete();
}else {
Log.d("TESTE","msg :"+ response.message());
Log.d("TESTE","errorBody :"+ response.errorBody().toString());
Toast.makeText(getBaseContext(),response.message(),Toast.LENGTH_SHORT).show();
}

}
@Override
public void onFailure(Call<String> call, Throwable t) {
Log.d("TESTE","DEU MERDA!!!");
Log.d("TESTE","throw :"+ t.getMessage());
Log.d("TESTE","cause :"+ t.getCause());
Log.d("TESTE","lmsg :"+ t.getLocalizedMessage());
Log.d("TESTE","Stack :"+ t.getStackTrace().toString());
Toast.makeText(getBaseContext(),t.getMessage(),Toast.LENGTH_SHORT).show();
}
});
}else {
Call<String> envioAcomp = geoPBService.uploadFotoAcompanhamento(idJurisdicionado,numObra,idAcomp,multipartBody);
envioAcomp.enqueue(new Callback<String>() {
@Override
public void onResponse(Call<String> call, Response<String> response) {
AttInfos();
Log.d("TESTE","FOTO ENVIADA COM SUCESSO!!!");
file.delete();
}
@Override
public void onFailure(Call<String> call, Throwable t) {
Log.d("TESTE","DEU MERDA!!!");
Toast.makeText(getBaseContext(),t.getMessage(),Toast.LENGTH_SHORT).show();
}
});
}
}
}

接口

public interface iGeoPBService {
@Multipart
@POST("obras/uploadFotoMedicao/{jurisdicionado}/{numObra}/{idMedicao}")
Call<String> uploadFotoMedicao(@Path("jurisdicionado") String idJurisdicionado,@Path("numObra")String numObra,@Path("idMedicao") String idMedicao, @Part MultipartBody.Part file);
@Multipart
@POST("obras/uploadFotoAcompanhamento/{jurisdicionado}/{numObra}/{idAcompanhamento}")
Call<String> uploadFotoAcompanhamento(@Path("jurisdicionado") String idJurisdicionado, @Path("numObra")String numObra, @Path("idAcompanhamento") String idAcompanhamento, @Part MultipartBody.Part file);

}

我的代码已经在其他答案的基础上进行了一些更改——关于使用retrofit2上传文件的类似问题，但在执行我的代码后，总是出现"onFailure">

Logcat显示：

throw :Expected value at line 1 column 1 path $

Stacktrace :[Ljava.lang.StackTraceElement;@b4b765b

我的文件被上传到服务器，但在改装"onFailure"响应方法时

我做错了什么？实际上，问题可能出在服务器端？

[EDIT]

我更改了代码中的一些内容，现在我得到了正确的"onResponse"。

只需将您的RequestBody更改为：

RequestBody requestFile = RequestBody.create(MediaType.parse("image/*"), file);

您发送的MediaType错误。。。
