问题 I want to connect to a proxy server that only allows HTTP connections, to speak with the target server by HTTPS. The proxy server documentation states that the only way to do that is by means of the HTTP Connect verb (they are planning to add direct HTTPS connections to the proxy server itself, but for the moment only HTTP connections are allowed). In my C++ program, I successfully connected and worked with the target server using ssl_stream 's during a couple of months, using boost::asio

问题 I need to expose an async REST api for c++ clients, that internally uses boost::beast for sending REST requests / receiving responses. The starting point is http_client_async.cpp example. Now the client will pass a callback function using this async api, that needs to be called at the end of the REST operation from the on_read() handler[http_client_async.cpp], passing the full response back to the caller. How can i achieve this? 回答1: but is there any way to invoke thie _callback through asio

问题 I have cases when there is a chunked response which is too big for beast, and I want to stop before I get to beast's body_limit , and continue handling the message from that point using plain boost::asio. Mind that this (obviously) means I already received the header and a large part of the body. I'm using it for a reverse proxy, so basically what I want to do is somehow send the incomplete response to the http client, while continuing relaying the remaining response data using boost::asio. I

问题 I am looking for a string implementation with fixed upper size that can be used in memcopy environment and that is trivially constructible and copyable. I found boost beast static_string, but IDK if my example works by accident or no? #include <algorithm> #include <iostream> #include <boost/beast/core/static_string.hpp> boost::beast::static_string<16> s1("abc"); int main(){ boost::beast::static_string<16> s2; std::copy_n((char*)&s1, sizeof(s2), (char*)&s2); s1.push_back('X'); std::cout << "--

问题 I am not very familiar with the boost::asio fundamentals. I am working on a task where I have connected to a web server and reading the response. The response is thrown at a random period, i.e. as and when the response is generated. For this I am using the boost::beast library which is wrapped over the boost::asio fundamentals. I have found that the async_read() function is waiting until it is receiving a response. Now, the thing is : in documentations & example the asynchronous way of

问题 I have an application of a client where I need to receive http "long running requests" from a server. I send a command, and after getting the header of the response, I have to just receive json data separated by \r\n until the connection is terminated. I managed to adapt boost beast client example to send the message and receive the header and parse it and receive responses from the server. However, I failed at finding a way to serialize the data so that I could process the json messages. The

问题 I'm trying to display an image file in the browser through a boost beast http server.
