我正在使用cpprestsdk“卡萨布兰卡”主分支与https网址,它在Windows和osx上运行但是当我在linux上运行时我收到“错误是ssl握手”
C++ exception with description "Error in SSL handshake" thrown in the test body.
我尝试使用firefox打开这个网址。
当我使用它与http url时,它工作正常 我在一个名为“http_client_asio.cpp”
的文件中检查了我发现此消息的代码void write_request()
{
// Only perform handshake if a TLS connection and not being reused.
if (m_connection->is_ssl() && !m_connection->is_reused())
{
const auto weakCtx = std::weak_ptr<asio_context>(shared_from_this());
m_connection->async_handshake(boost::asio::ssl::stream_base::client,
m_http_client->client_config(),
m_http_client->base_uri().host(),
boost::bind(&asio_context::handle_handshake, shared_from_this(), boost::asio::placeholders::error),
// Use a weak_ptr since the verify_callback is stored until the connection is destroyed.
// This avoids creating a circular reference since we pool connection objects.
[weakCtx](bool preverified, boost::asio::ssl::verify_context &verify_context)
{
auto this_request = weakCtx.lock();
if(this_request)
{
return this_request->handle_cert_verification(preverified, verify_context);
}
return false;
});
}
else
{
m_connection->async_write(m_body_buf, boost::bind(&asio_context::handle_write_headers, shared_from_this(), boost::asio::placeholders::error));
}
}
void handle_handshake(const boost::system::error_code& ec)
{
if (!ec)
{
m_connection->async_write(m_body_buf, boost::bind(&asio_context::handle_write_headers, shared_from_this(), boost::asio::placeholders::error));
}
else
{
report_error("Error in SSL handshake", ec, httpclient_errorcode_context::handshake);
}
}
在客户端我喜欢这样的http客户端
http_client client(U("https://www.bing.com/"));
我该如何修复此错误?
答案 0 :(得分:3)
我在尝试连接到https网址时遇到了同样的问题。
首先,如果您不需要连接到https,则只需将您的网址替换为http网址。
另一种解决方案是将http_client_config凭据验证设置为false。像这样:
http_client_config config;
config.set_validate_certificates(false);
但是,如果您需要使用包含安全性的https连接,则必须包含本地证书文件(通常是CRT或DEM文件)并将其设置为http_client配置中的回调:
http_client_config config;
config.set_ssl_context_callback([]((boost::asio::ssl::context &ctx) {
ctx.load_verify_file("PATH_TO_CERTIFICATE_FILE");
});
