我正在连接到一个总是以 JSON 形式回复的 WebSocket。我看到 websocket_incoming_message 有一个 extract_string 方法，但是在使用 json:value 尝试了很多东西之后，似乎你只能通过一个接一个地插入键值对来动态构建 JSON 数组。我在这里遗漏了什么还是有办法从 websocket_incoming_message 获取输出并将其直接转换为 json:value 数组？
websocket_client client;
//start socket connection to server
try {
std::cout << "s
----------
client.connect(U("wss://XZXXXZZy.com/ws?account_id=4de3f308f2f8d3247As70228f94e0d2aAea&ws_key=reception")).wait();
}
catch (const std::exception&e)
{
std::cout << e.what() << std::endl;
}
//send messages to the server
//websocket_outgoing_message msg;
//msg.set_pong_message();
//std::cout << "\n...........2nd.........;";
//std::string data = "hii";
//client.send(msg).then([]() {
//
//
//
//
// /* Successfully sent the message. */ });
//std::cout << " Successfully sent the message.";
//std::cout << "\n...........3rd.........;";
//receive messages from the server
client.receive().then([](websocket_incoming_message msg) {
std::cout << "receiving data from socket";
return msg.extract_string();
}).then([](std::string body) {
//FETCHING THE DATA FROM BODY. "TEXT/JSON"
std::cout << "displaying the data";
std::cout << body << std::endl;
const json::value& v1 = body.substr;
utility::string_t jsonval = v1.serialize();
auto array = v1.at(U("rows")).as_array();
for (int i = 0; i<array.size(); ++i)
{
auto id = array[i].at(U("id")).as_string();
std::wcout << "\n" << id;
auto key = array[i].at(U("key")).as_string();
std::wcout << "\n" << key;
auto array2 = array[i].at(U("value")).as_array();
std::wcout << array2[0];
std::wcout << array2[1];
}
}
);
//close the connection
client.close().then([]() {
std::cout << "successfully close socket connction";
/* Successfully closed the connection. */
});
