大神，请教一下，使用C++ Rest SDK异步请求一个错误的地址，为什么捕获不到异常，而且程序会死机？

void sendHTTP(std::string strurl)
{
try
{
std::wstring url = StringToWString(strurl);
web::http::client::http_client_config client_config;
client_config.set_timeout(std::chrono::seconds(10000));
web::http::client::http_client client(url, client_config);
auto task = client.request(web::http::methods::POST);
}
catch (web::uri_exception)
{
std::cout << "uri_exception" << std::endl;

catch (web::json::details::json_error)

std::cout << "json_error" << std::endl;

std::cout << "web_proxy_mode" << std::endl;
}

std::cout << "sendHTTP error" << std::endl;

std::string URL = "http://127.0.0.1:8080/test/test.go&data="+ URLEncode("{"row":[{"test":34,"test2" : 1}, {"test":34,"test2" : 1}]}");//网址不存在
sendHTTP(URL);
}
return 0;
}

@zhanMan 异步接口肯定不能够通过try catch来捕获异常，你看看它异步返回值里面有没有什么参数可以说明返回失败了呢？
