不,您不需要 Application 对象。这是一个功能齐全的示例:
$ httpsget https://httpbin.org/user-agent
{
"user-agent": "Poco HTTPSClientSession"
}
代码:
#include "Poco/StreamCopier.h"
#include "Poco/URI.h"
#include "Poco/Exception.h"
#include "Poco/SharedPtr.h"
#include "Poco/Net/SSLManager.h"
#include "Poco/Net/KeyConsoleHandler.h"
#include "Poco/Net/ConsoleCertificateHandler.h"
#include "Poco/Net/HTTPSClientSession.h"
#include "Poco/Net/HTTPRequest.h"
#include "Poco/Net/HTTPResponse.h"
#include <memory>
#include <iostream>
using namespace Poco;
using namespace Poco::Net;
class SSLInitializer {
public:
SSLInitializer() { Poco::Net::initializeSSL(); }
~SSLInitializer() { Poco::Net::uninitializeSSL(); }
};
int main(int argc, char** argv)
{
SSLInitializer sslInitializer;
SharedPtr<InvalidCertificateHandler> ptrCert = new ConsoleCertificateHandler(false);
Context::Ptr ptrContext = new Context(Context::CLIENT_USE, "", "", "rootcert.pem", Context::VERIFY_STRICT, 9, false, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");
SSLManager::instance().initializeClient(0, ptrCert, ptrContext);
try
{
if (argc > 1)
{
URI uri(argv[1]);
HTTPSClientSession s(uri.getHost(), uri.getPort());
HTTPRequest request(HTTPRequest::HTTP_GET, uri.getPath());
request.set("user-agent", "Poco HTTPSClientSession");
s.sendRequest(request);
HTTPResponse response;
std::istream& rs = s.receiveResponse(response);
StreamCopier::copyStream(rs, std::cout);
}
}
catch (Exception& ex)
{
std::cout << ex.displayText() << std::endl;
return 1;
}
return 0;
}
