我在尝试使 QNetwork 类在 Ubuntu 18.04 上与 Qt5.11.1 一起工作时遇到问题

我的系统上安装了 openssl 1.1.0g 和 libssl-dev。

Qt 使用的 openssl 版本是 1.0.2k。我已经检查过QSslSocket::sslLibraryBuildVersionString()。加QSslSocket::supportsSsl()回报false。

我试图解决这个问题，但我总是遇到这些错误：

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

qt.network.ssl: QSslSocket: cannot resolve OPENSSL_add_all_algorithms_conf
qt.network.ssl: QSslSocket: cannot resolve SSLeay
qt.network.ssl: Incompatible version of OpenSSL

我已经检查了多个关于此的问题和论坛，但似乎没有什么对我有用。有人知道吗？

我终于设法使它工作。

我已经从源代码安装了 openssl 1.0.2k。我已经在这里下载了我需要的版本，并按照此页面上的教程进行操作。

这样做之后，我仍然有一些错误，但不是不兼容版本的错误。为了解决我已经安装的问题libssl1.0-dev，一切都很好（感谢这个人）。

我希望这会对某人有所帮助。

我已将libcrypto.soand libssl.so(v1.0.2) 复制到我当前的编译器 lib 目录 ( <QTDIR>/5.11.1/gcc_64/lib)。就我而言，我在/usr/lib/x86_64-linux-gnu/:libssl.so.1.0.0和中使用了这些 2 个库libcrypto.so.1.0.0，复制并重命名。它对我有用。

我解决了这个问题，通过这种方式创建了一个到 openssl 1.1.0 的符号链接：

在 /opt/f5/vpn/lib 中创建覆盖 libcrypto.so.1.0.0 和 libssl.so.1.0.0 的符号链接：

    sudo ln -sf /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 /opt/f5/vpn/lib/libcrypto.so.1.0.0 

    sudo ln -sf /usr/lib/x86_64-linux-gnu/libssl.so.1.1 /opt/f5/vpn/lib/libssl.so.1.0.0

我在 Ubuntu 16.04 上使用 Qt 5.13.1 时遇到了这个问题。

在我的 Qt 环境中和的值是QSslSocket::sslLibraryBuildVersionString()和。QSslSocket::supportsSsl()"OpenSSL 1.1.1b 26 Feb 2019"false

每次QNetworkAccessManager访问 https 地址时都会生成此输出：

qt.network.ssl: QSslSocket: cannot resolve OPENSSL_init_ssl
qt.network.ssl: QSslSocket: cannot resolve OPENSSL_init_crypto
qt.network.ssl: QSslSocket: cannot resolve ASN1_STRING_get0_data

qt.network.ssl: QSslSocket: cannot resolve OpenSSL_version_num
qt.network.ssl: QSslSocket: cannot resolve OpenSSL_version
qt.network.ssl: Incompatible version of OpenSSL
qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed

以上解决方案都不适合我。我在我的 Ubuntu 上安装了Homebrew包管理器，然后像这样安装了openssl@1.1：

$ brew install openssl@1.1

然后我只是将这些行添加到我的项目文件中：

LIBS += -L/home/linuxbrew/.linuxbrew/Cellar/openssl@1.1/1.1.1c/lib -lssl -lcrypto
INCLUDEPATH += /home/linuxbrew/.linuxbrew/Cellar/openssl@1.1/1.1.1c/include

的值QSslSocket::sslLibraryBuildVersionString()仍然是旧值"OpenSSL 1.1.1b 26 Feb 2019"，但值QSslSocket::supportsSsl()变成了true，它解决了我的问题。
