我要做的是发送https请求 https://mapi.alipay.com/gateway.do?在QT并获得回复。每当我 发送请求我得到以下错误。
qt.network.ssl:QSslSocket:无法调用未解析的函数SSLv23_client_method qt.network.ssl:QSslSocket:无法调用 未解决的函数SSL_CTX_new qt.network.ssl:QSslSocket:不能 调用未解析的函数SSL_library_init qt.network.ssl:QSslSocket: 无法调用未解析的函数ERR_get_error qt.network.ssl: QSslSocket:无法调用未解析的函数ERR_get_error失败 “创建SSL上下文时出错()
我被告知我需要SSL证书,所以我使用了
openssl s_client -connect mapi.alipay.com:443 -showcerts
获得证书。但是什么时候
如何在QT中为我的项目代码添加SSL证书?
#include <QCoreApplication>
#include <QDebug>
#include <QNetworkAccessManager>
#include <QNetworkRequest>
#include <QNetworkReply>
#include <QUrl>
#include <QUrlQuery>
#include <QFile>
#include <QSslSocket>
void sendRequest();
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
sendRequest();
return a.exec();
}
void sendRequest(){
// create custom temporary event loop on stack
QEventLoop eventLoop;
// "quit()" the event-loop, when the network request "finished()"
QNetworkAccessManager mgr;
QObject::connect(&mgr, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
// the HTTP request
QNetworkRequest req( QUrl( QString("https://mapi.alipay.com/gateway.do/_input_charset=UTF-8¤cy=USD¬ify_url=10.237.221.84:80&out_trade_no=123456789&partner=2088101122136241&sign=760bdzec6y9goq7ctyx96ezkz78287de&subject=Coke&sign_type=MD5&service=create_forex_trade&total_fee=0.01") ) );
QNetworkReply *reply = mgr.get(req);
eventLoop.exec(); // blocks stack until "finished()" has been called
if (reply->error() == QNetworkReply::NoError) {
//success
qDebug() << "Success" <<reply->readAll();
delete reply;
}
else {
//failure
qDebug() << "Failure" <<reply->errorString();
delete reply;
}
}
答案 0 :(得分:1)
要向Qt程序添加其他SSL证书,您可以使用:
QSslSocket::addDefaultCaCertificates("example.pem");
但是,我认为这不会解决您的任何错误。您的问题中的错误与缺少的SSL证书无关,但与缺少的SSL功能无关。您可能正在使用过时的SSL库? (例如,在Windows上较旧或不兼容的libeay32.dll和ssleay32.dll版本?)
