[英]How to install OpenSSL 1.1.0 for Qt on Windows?
My goal is to get the source code (or images) from a webpage over a SSL connection using QNetworkRequest
with the QNetworkAccessManager
. 我的目标是使用
QNetworkRequest
和QNetworkAccessManager
通过SSL连接从网页上获取源代码(或图像)。
OpenSSL 1.1.0 doesn't work with Qt 5.8! OpenSSL 1.1.0不适用于Qt 5.8! Look in Edit 2 for the install solution!
在Edit 2中查找安装解决方案!
First Try: Get the ssleay32.lib and the libeay32.lib and copy them into the debug and the release folder. 首先尝试:获取ssleay32.lib和libeay32.lib并将它们复制到debug和release文件夹中。 Dont work.
不要工作
Second Try: (deleted because it's nonsense) But it doesnt work again. 第二次尝试:(由于废话而删除),但是它不再起作用。
Code (works fine for normal http): 代码(适用于正常的http):
QUrl url = QUrl(name);
data.clear();
QNetworkRequest *request = new QNetworkRequest(url);
request->setRawHeader("User-Agent", userAgent);
QSslConfiguration sslConfiguration(QSslConfiguration::defaultConfiguration());
request->setSslConfiguration(sslConfiguration);
reply = webCtrl->get(*request);
connect(webCtrl, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*)));
connect(reply, SIGNAL(readyRead()), this, SLOT(onReadyRead()));
connect(reply, SIGNAL(finished()), this, SLOT(onReplyFinished()));

Edit 1: I found this Artikel and OpenSSL 1.1.0 will be working with Qt 5.10 but not in Qt 5.8 what I am using. 编辑1:我发现此 Artikel和OpenSSL 1.1.0将与Qt 5.10一起使用,但在Qt 5.8中无法使用。 And in this Artikel I found the
QSslSocket::sslLibraryBuildVersionString()
command and I Need OpenSSL Version: OpenSSL 1.0.2h 3 May 2016
. 在此 Artikel中,我找到了
QSslSocket::sslLibraryBuildVersionString()
命令,我需要OpenSSL版本: OpenSSL 1.0.2h 3 May 2016
。
I will checkout the other OpenSSL Version later and edit this post if it is working or not. 稍后,我将签出其他OpenSSL版本,并编辑此帖子(不管它是否有效)。
Edit 2: Download OpenSSL 1.0.2h 3 May 2016
and Install 7zip and Perl. 编辑2:
OpenSSL 1.0.2h 3 May 2016
下载OpenSSL 1.0.2h 3 May 2016
然后安装7zip和Perl。 Extract the openSSL folder and follow INSTALL.W64
. 解压缩openSSL文件夹,然后按照
INSTALL.W64
。 Go to the bin
folder and copy libeay32-xxx.dll
and ssleay32-xxx.dll
to the application folder and rename the files to libeay32.dll
and ssleay32.dll
. 转到
bin
文件夹,将libeay32-xxx.dll
和ssleay32-xxx.dll
到应用程序文件夹,并将文件重命名为libeay32.dll
和ssleay32.dll
。 Thanks @[Max Go]. 谢谢@ [Max Go]。
Now the SSL connection finaly works, but I get an error message when I Close the application and the web connection was used at runtime. 现在,SSL连接最终完成了,但是当我关闭应用程序并且在运行时使用了Web连接时,我收到一条错误消息。
Exception at 0x000000007772D1CB (ntdll.dll) in onlineTest.exe: 0xC0000005: Access Violation reading position 0x0000000000000074.

Edit 3: I forgot to compile the -d debug .dll's. 编辑3:我忘了编译-d调试.dll。 Simply change the compiler mode to Debug, generate the Debug .dll's, rename if needed without the -d and then copy the debug .dll's into the debug folder and the normal .dll's into the release folder.
只需将编译器模式更改为Debug,生成Debug .dll,然后在不使用-d的情况下重命名(如果需要),然后将debug .dll复制到debug文件夹,将普通.dll复制到release文件夹。
Here's the script I use to build OpenSSL automatically from a Visual Studio prompt. 这是我用来从Visual Studio提示自动构建OpenSSL的脚本。 It will build either a 32 or 64 bit library, depending on what compiler is enabled.
根据启用的编译器,它将构建32位或64位库。
