QNetworkReply* reply = m_pNetWorkManager->post(request, append);
这句代码执行完之后，执行流程需要回到事件循环当中，post才会被执行。
可以向下面这样异步执行：
void on_button_clicked()
{
QNetworkRequest request;
QByteArray line;
request.setUrl(QUrl("http://192.168.1.117:8070/api/yakInterface/yakRecordRealPosition/addYakRecordRealPosition"));
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");
QByteArray append("{\"id\":null,\"simCode\":134.0,\"longitude\":12345.0,\"latitude\":12345.0,\"height\":15.0,\"time\":12345,\"deviceCode\":\"M110 - niu\",\"speed\":180}");
m_reply = m_pNetWorkManager->post(request, append);
connect(m_reply, &QNetworkReply::finished, this, &MainWindow::on_reply_finished);
}
void on_reply_finished()
{
if (m_reply->error() == QNetworkReply::NoError) {
// 成功
} else {
// 失败
}
}
或者同步：
void on_button_clicked()
{
QNetworkRequest request;
QByteArray line;
request.setUrl(QUrl("http://192.168.1.117:8070/api/yakInterface/yakRecordRealPosition/addYakRecordRealPosition"));
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");
QByteArray append("{\"id\":null,\"simCode\":134.0,\"longitude\":12345.0,\"latitude\":12345.0,\"height\":15.0,\"time\":12345,\"deviceCode\":\"M110 - niu\",\"speed\":180}");
QNetworkReply *reply = m_pNetWorkManager->post(request, append);
QEventLoop loop;
connect(reply, &QNetworkReply::finished, &loop, &QEventLoop::quit);
loop.exec();
if (reply->error() == QNetworkReply::NoError) {
// 成功
} else {
// 失败
}
}
