新手求教，历程无法使用，在debug的时候在replyfinished函数开始处设置断点，一直没有触发
这是pro文件：
QT += core gui network
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = weatherget
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
FORMS += mainwindow.ui
这是头文件：

这是源文件：

QString all=codec->toUnicode((reply->readAll()));
