Qt、WIndows和OpenSSL-无法调用未解析的函数xyz

我最近在运行Qt5.9.1的Windows 10计算机上安装了ArcGIS运行时SDK。尝试使用一个ArcGIS模板构建一个简单的

QWidget

应用程序时，出现以下错误：

qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new
qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init

这个问题似乎很常见，但大多数谷歌搜索结果都给出了Linux系统的答案

我已经做了以下工作：

• 下载并安装OpenSSL（来自GnuWin32 OpenSSL）
• 跨

  libeay32.dll

  和

  libssl32.dll

  复制到生成文件夹
• 将include路径添加到Qt-pro文件中
• 已验证

  网络

  位于pro文件的

  QT+=

  config部分

然而，上述这些都没有带来任何不同。我正在运行MSVC 2015 32位工具包。

您必须将静态库添加到项目中

找出

libeay32.lib

和

libssl32.lib

并将它们添加到项目中

我认为您需要两个dll文件：libeay32.dll和ssleay32.dll。我使用与您相同的qt版本，因此您可以从下载它们或直接从中获取zip（这对我很有用）

Qt使用不同版本的openssl库，因此如果您不确定，则应使用下面的静态函数在代码中对其进行测试：

QSslSocket::sslLibraryBuildVersionString();
