我正在尝试通过包含 POCO 来修改 C++ 程序，以便能够执行 HTTP 请求并接收结果。基本上，我只需要在另一个 C++ 程序中提供用户名和密码并得到一个简单的“OK”或“ERROR”响应。
我根本不熟悉 C++（主要使用 Java）。我构建了 POCO 项目并安装了它，没有任何问题，但是当我将它添加到项目中时，我在构建时遇到了一些编译器错误：

我的代码片段如下：
#include <Poco/Net/HTTPRequest.h>
#include <Poco/Net/HTTPClientSession.h>
#include <Poco/Net/HTMLForm.h>
#include <Poco/StreamCopier.h>
string RTMPAppProtocolHandler::GetAuthPassword(string user) {
INFO("Testing auth: %s", STR(user));
Poco::Net::HTTPClientSession s("www.somehost.com");
//s.setProxy("localhost", srv.port());
Poco::Net::HTTPRequest request(Poco::Net::HTTPRequest::HTTP_GET, "/large");
Poco::Net::HTMLForm form;
form.add(“entry1”, “value1”);
form.prepareSubmit(request);
s.sendRequest(request);
Poco::Net::HTTPResponse response;
std::istream& rs = s.receiveResponse(response);
Poco::StreamCopier::copyStream(rs, std::cout);
return user;
}
我在做傻事吗？我需要修改的只是与 HTTP 服务器的这个小交互，所以我只是在寻找一个非常简单的解决方案，但发现很难找到容易工作的东西（主要是因为我不熟悉 C++）
