我正在使用Retrofit 2,我想调用一个Web服务将我的图像上传到我的服务器。服务器端我使用Phalcon PHP并检查是否有要上传的文件。但我从来没有上传过的文件。我可以获取description参数但不能获取文件参数。
你能告诉我我的安卓代码是否正常?我不知道出了什么问题。
ApplicationService
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类
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);
}
}
上传文件
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());
}
});
}
答案 0 :(得分:1)
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);
