How should I make my process send requests to the target when using OATPP

[ZzMLvzZ-792998470]

I am currently using C++to create a video engine, and I can use the OATPP framework to receive external requests and execute corresponding methods. But now I hope to send a post request to the backend at the specified address when executing some of my methods. I tried to encapsulate a class but it doesn't seem to work. Can you help me solve my problem? Thank you very much!

``
class RequestHandler {
public:
RequestHandler() {}

~RequestHandler() {}

// 注册地址和端口
void registerConnection(const std::string& url = "http://127.0.0.1", int port = 9002) {
    _connectionProvider =  oatpp::network::tcp::client::ConnectionProvider
            ::createShared({url, static_cast<v_uint16>(port)});
    _requestExecutor = oatpp::web::client::HttpRequestExecutor::createShared(_connectionProvider);
}
// 解绑
void unregisterConnection() {
    _connectionProvider->stop();
    _connectionProvider = nullptr;
    _requestExecutor = nullptr;
}
// 发送请求并返回response
std::shared_ptr<oatpp::web::protocol::http::incoming::Response> sendRequest(const std::string& order, const std::string& endpoint, const std::string& message) {
    auto headers = oatpp::web::protocol::http::Headers();
    headers.put("user-agent", "super-agent");

    if(!_requestExecutor) {
        std::cerr << "_requestExecutor is not exist" << std::endl;
        return nullptr;
    }

    auto response = _requestExecutor->executeOnce(order, endpoint, headers, nullptr);
    return response;
}

private:
std::shared_ptroatpp::network::tcp::client::ConnectionProvider _connectionProvider;
std::shared_ptroatpp::web::client::HttpRequestExecutor _requestExecutor;
};
``

my error：
zhaozimo@zhaozimodeMacBook-Pro test % sh livePlatform_test_request.sh
server=oatpp/1.3.0

Try pass _requestExecutor->getConnection() as the last parameter of _requestExecutor->executeOnce()

You'd better refer to the documentation and implement your own apiclient to send a request.

多谢老哥 我对这个框架还不是很熟 剩下的东西我看看文档自己解决吧

[doufu3344]

_connectionProvider = oatpp::network::tcp::client::ConnectionProvider
::createShared({url, static_cast<v_uint16>(port)});

The url is incorrect, this parameter represents the host address, so it should be 127.0.0.1 not http://127.0.0.1

牛的老哥 我搞定了！ 十分感谢！
