我运行Windows 7计算机,在我的D:驱动器上安装了openssl 1.1.0。我正在使用Qt5.9.0

这是触发错误的代码:
QString Commands::getPublicIp()
{
QString temp;
QNetworkAccessManager networkManager;
QUrl url("http://api.ipify.org");
QString query = "format=json";
url.setQuery(query);
QNetworkReply* reply = networkManager.get(QNetworkRequest(url));
QObject::connect(
reply
, &QNetworkReply::finished
, [&](){
if(reply->error() != QNetworkReply::NoError) {
return QString();
} else {
QJsonObject jsonObject= QJsonDocument::fromJson(reply->readAll()).object();
QHostAddress ip(jsonObject["ip"].toString());
temp = QString("002 " + ip.toString());
}
reply->deleteLater();
}
);
return temp;
}
我一直收到qt.network.ssl错误,在链接openssl之后我不断收到编译错误:
: - 1:错误:找不到D:\ OpenSSL-Win32 \ lib:权限被拒绝
: - 1:错误:找不到-llibssl
collect2.exe:-1:错误:错误:ld返回1退出状态
即使我目前没有使用OpenSSL,我也愿意稍后再使用它。
答案 0 :(得分:0)
仅Qt 5.10支持OpenSSL 1.1.0。请使用OpenSSL 1.0.2l,您可以使用与npcglib编译器匹配的预构建包。
您的LIBS +=
包含是正确的,但似乎您的计算机没有权限或找不到库。无法告知为什么会发生此错误。验证文件夹中是否存在库以及用户是否有权访问。
QNetworkReply *QNetworkAccessManager::get(const QNetworkRequest &request)
是一个异步调用。您的函数QString Commands::getPublicIp()
可能会在请求完成之前返回一个空的QString。
