如何在c++ /CLI中编写这一行

我正在使用Visual c++调用web服务。我需要绕过无效的SSL证书,因为我得到这个错误-
请求失败。底层连接已关闭:无法为SSL/TLS安全通道建立信任关系。
在c#中写同样的东西时,我使用了这一行-
System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
,它对我有效。
如何在Visual c++中实现同样的事情?如何在Visual c++中编写同一行?
您需要显式地创建回调对象并将其分配给相应的属性。
using namespace System;
using namespace System::Net;
using namespace System::Net::Security;
using namespace System::Security::Cryptography::X509Certificates;
static bool ValidateServerCertificate(
Object^ sender,
X509Certificate^ certificate,
X509Chain^ chain,
SslPolicyErrors sslPolicyErrors)
{
return true;
}
int main(array<System::String ^> ^args)
{
// create callback object, pointing to your function
System::Net::Security::RemoteCertificateValidationCallback^ clb = gcnew RemoteCertificateValidationCallback(ValidateServerCertificate);
// assign it to the property
System::Net::ServicePointManager::ServerCertificateValidationCallback = clb;
return 0;
}
VS 2010中的c++/CLI不支持lambdas,因此您必须将委托编写为普通函数:
using namespace System::Net;
using namespace System::Net::Security;
using namespace System::Security::Cryptography::X509Certificates;
bool returnTrueCallback(
Object^ sender, X509Certificate^ certificate, X509Chain^ chain,
SslPolicyErrors sslPolicyErrors)
{
return true;
}
...
ServicePointManager::ServerCertificateValidationCallback =
gcnew RemoteCertificateValidationCallback(returnTrueCallback);
