無法使用<QJsonValue><QJsonObject>

Question

我使用 QJsonValue和 QJsonObject

即使當我添加QT + =核心問題。我使用QT 5.5 有沒有人知道可能是什麼問題。 在此先感謝

Answer 1

Pro file:  

QT += core gui webkit network 
TEMPLATE = app 
SOURCES += main.cpp \ 
apiservis.cpp 
HEADERS += \ 
apiservis.h 
QT = core 
QT -= gui 
QT += webkit 
QT += webkit webkitwidgets 
QT += network 
TARGET = cpp 
CONFIG += console 
CONFIG -= app_bundle 
TARGET = main 
DISTFILES += \ 
API_kljuc.txt 

And in the .h file I have: 
#include <QCoreApplication> 
#include <iostream> 
#include <cmath> 
#include <iomanip> 
#include <vector> 
#include <string.h> 
#include <locale> 
#include <sstream> 
#include <fstream> 
#include <string> 
#include <curl/curl.h> 
#include <stdio.h> 
#include <QHash> 
#include <QVariantMap> 
#include <QWebFrame> 
#include <QWebView> 
#include <QNetworkReply> 
#include <QCoreApplication> 
#include <QDebug> 
#include <QNetworkAccessManager> 
#include <QNetworkRequest> 
#include <QUrl> 
#include <QObject> 
#include <QJsonArray> 
#include <QJsonValue> 
#include <QJsonObject> 

But when I try to build it, error is: QJsonARRay:No such file or directory.
