【问题描述】：

我想使用 QNetworkAccessManager 通过 https 访问页面，但是当我尝试它时，我得到以下输出：

qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks  
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_set_id_callback

qt.network.ssl: QSslSocket: cannot call unresolved function SSLeay  
qt.network.ssl: QSslSocket: cannot call unresolved function  SSLeay_version

我使用的是 arch x86_64 和 QT 5.9。

在终端输入后：openssl version -v 我得到了OpenSSL 1.1.0f 25 May 2017，所以它是最新的。

我也添加到 main.cpp：

qDebug() << "SSL version use for build "
         << QSslSocket::sslLibraryBuildVersionString();
qDebug() <<"SSL version use for run-time "
         << QSslSocket::sslLibraryVersionNumber();

我得到了以下信息：

SSL version use for build:  "OpenSSL 1.0.1e-fips 11 Feb 2013"
SSL version use for run-time:  0

您有什么建议可以解决这个问题吗？

【参考方案1】：

检查您主机上安装的OpenSSL 的版本

QNetworkAccessManager 尝试在运行时加载的库中查找函数。

很可能您安装了旧版本的OpenSSL。

还要检查 thread 上的 Qt 与 OpenSSL 编译时/运行时依赖项
