私はこのような改造2から画像をアップロードするために使用し、それは
File file = new File(image.getPath());
RequestBody mFile = RequestBody.create(MediaType.parse("image/*"), file);
MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("gallery", file.getName(), mFile);
RequestBody filename = RequestBody.create(MediaType.parse("text/plain"), id);
final NetworkCall networkCall=new NetworkCall(this);
Call<ResponseBody> call = networkCall.getRetrofit(false).uploadImage(filename, fileToUpload);
call.clone().enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
}
});
ここ
私のネットワーク呼び出しクラスされ、正しく働いていた:
public class NetworkCall {
Context context;
ProgressDialog progressDialog;
public NetworkCall(Context context){
this.context = context;
}
public IApi getRetrofit(boolean isShowLoading){
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.connectTimeout(0, TimeUnit.SECONDS).readTimeout(0,TimeUnit.SECONDS);
httpClient.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
Request request = original.newBuilder()
.header("Content_type","application/json")
.header("Accept", "application/json")
.method(original.method(), original.body())
.build();
return chain.proceed(request);
}
});
Gson gson = new GsonBuilder()
.setLenient()
.create();
OkHttpClient client = httpClient.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
if (isShowLoading&&context instanceof BaseActivity)
showLoading();
// prepare call in Retrofit 2.0
IApi api = retrofit.create(IApi.class);
// Call<BaseResponce> call = api.callService(json);
//asynchronous call
// call.enqueue(this);
return api;
}
private void showLoading(){
try {
((BaseActivity)context).runOnUiThread(new Runnable() {
@Override
public void run() {
progressDialog = new ProgressDialog(context);
progressDialog.setMessage("Please wait...");
progressDialog.setCancelable(false);
progressDialog.show();
}
});
}catch (Exception e){
e.printStackTrace();
}
}
public void dismissLoading(){
try {
((BaseActivity)context).runOnUiThread(new Runnable() {
@Override
public void run() {
progressDialog.cancel();
progressDialog.dismiss();
}
});
}catch (Exception e){
e.printStackTrace();
}
}
}
iがIAPIクラスでこれを使用
@Multipart
@POST("events/file_upload.json")
Call <ResponseBody> uploadImage(@Part("event_id") RequestBody id,@Part MultipartBody.Part part);
