[英]Android Retrofit 2 file upload
我正在使用Retrofit 2,並且想調用一個Web服務以將圖像上傳到服務器。 服務器端,我使用的是Phalcon PHP ,我檢查是否有要上傳的文件。 但是我從來沒有要上傳的文件。 我可以獲取description參數,但不能獲取file參數。
你能告訴我我的Android代碼是否正常嗎? 我不知道怎么了
應用服務
public interface ApplicationService {
...
// My other web services works well
@Multipart
@POST("/path/to/uploadPictures")
Call<ResponseBody> upload(@Part("description") RequestBody description,
@Part("file") RequestBody file);
}
ServiceGenerator類
public class ServiceGenerator {
public static final String API_BASE_URL = Globals.SERVER_NAME;
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
private static Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl(API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create());
public static <S> S createService(Class<S> serviceClass) {
Retrofit retrofit = builder.client(httpClient.build()).build();
return retrofit.create(serviceClass);
}
}
上傳文件調用
private void uploadFile(String filename) {
// create upload service client
ApplicationService service = ServiceGenerator.createService(ApplicationService.class);
File file = new File(this.getExternalFilesDir(Environment.DIRECTORY_PICTURES), filename);
// create RequestBody instance from file
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
// add another part within the multipart request
String descriptionString = "hello, this is description speaking";
RequestBody description = RequestBody.create(MediaType.parse("multipart/form-data"), descriptionString);
// finally, execute the request
Call<ResponseBody> call = service.upload(description, requestFile);
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call,
Response<ResponseBody> response) {
Log.v("Upload", "success");
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.e("Upload error:", t.getMessage());
}
});
}
而不是@Part("file") MultipartBody.Part file
使用@Part MultipartBody.Part file
File file = new File(getRealPathFromURI(data.getData()));
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), getRealPathFromURI(data.getData()));
MultipartBody.Part multipartBody =MultipartBody.Part.createFormData("file",file.getName(),requestFile);
