C++ Function Completing Before Other Function Finishes

由 [亡魂溺海] 提交于 2019-12-11 03:48:35
问题 I am coding a C++ program to interact with the internet using the C++ REST SDK. I have a main function and a webCommunication function. The code is similar to below: void webCommunication(data, url) { //Communicate with the internet using the http_client //Print output } int main() { //Obtain information from user webCommunication(ans1, ans2); system("PAUSE"); } However, it seems that the main function is progressing before the webCommunication function is finished. If I make webCommunication

Howto reconnect to a server which does not answer to close()

由 老子叫甜甜 提交于 2019-12-08 04:31:25
问题 I am using the C++ REST SDK ("Casablanca") to receive feed from websocket servers. Sometimes, I need to close the connection and reconnect. The library does not have a reconnect function, so I close the old connection and simply open a new one. The problem is that the server on the other side does, as it seems, not answer to my close message. This is the code: web::websockets::client::websocket_callback_client* m_clClient; ///... void Connection::reconnect() { std::cout << "Debug 1" << std:

no suitable user-defined conversion from utility::string_t to std::string

由 為{幸葍}努か 提交于 2019-11-30 20:36:32
I am using the casablanca C++ Rest library to make HTTP requests. The problem is that this gives a utility::string_t string as output and I can't quite find any way to convert this to a classic std::string. Any ideas? client.request(methods::GET).then([](http_response response) { if(response.status_code() == status_codes::OK) { string_t s = response.extract_string().get(); } }); If you see the documentation for C++ REST SDK from github, you'll find a typedef C++ Rest SDK - utility Namespace Reference typedef std::string string_t; So no need to convert it. Both are same types. Depending on what
