c++ - cpprest 服务器端向客户端reply后，客户端收不到http_response
客户端向服务端request请求后，服务器端能接收到http_request,然后reply回复，客户端就无法收到这个http_response，帮忙看看，实在找不出来原因了
客户端代码
#include "cpprest/http_client.h"
#include "cpprest/filestream.h"
using namespace utility; // Common utilities like string conversions
using namespace web; // Common features like URIs.
using namespace web::http; // Common HTTP functionality
using namespace web::http::client; // HTTP client features
using namespace concurrency::streams; // Asynchronous streams
int main(int argc, char* argv[])
{
auto fileStream = std::make_shared<ostream>();
// Open stream to output file.
pplx::task<void> requestTask = fstream::open_ostream(U("results.html")).then([=](ostream outFile)
{
*fileStream = outFile;
// Create http_client to send the request.
http_client client(U("http://www.bing.com/"));
http_client localclient(U("http://localhost:8888"));
return localclient.request(methods::GET);
})
.then([=](http_response response)
{
printf("Received response status code:%u\n", response.status_code());
system("pause");
return response.body().read_to_end(fileStream->streambuf());
})
.then([=](size_t)
{
return fileStream->close();
});
try
{
requestTask.wait();
}
catch (const std::exception &e)
{
printf("Error exception:%s\n", e.what());
system("pause");
}
return 0;
}
服务器代码
#include "cpprest/json.h"
#include "cpprest/http_listener.h"
#include "cpprest/uri.h"
#include "cpprest/asyncrt_utils.h"
#include "cpprest/http_client.h"
using namespace web::http::experimental::listener;
using namespace web::http;
using namespace web;
void handle_get(http_request message)
{
message.reply(status_codes::OK, U("Hello, World!"));
};
void handle_post(http_request message)
{
message.reply(status_codes::NotFound);
};
void handle_put(http_request message)
{
message.reply(status_codes::NotFound);
};
void handle_delete(http_request message)
{
message.reply(status_codes::NotFound);
};
#define TRACE(msg) std::wcout << msg
#define TRACE_ACTION(a, k, v) std::wcout << a << L" (" << k << L", " << v << L")\n"
int main(int argc, char ** argv)
{
uri_builder uri(U("http://localhost:8888"));
http_listener listener(uri.to_uri());
listener.support(methods::GET, handle_get);
listener.support(methods::POST, handle_post);
listener.support(methods::PUT, handle_put);
listener.support(methods::DEL, handle_delete);
try
{
listener
.open()
.then([&listener](){TRACE(L"\nstarting to listen\n"); })
.wait();
while (true);
}
catch (std::exception const & e)
{
std::wcout << e.what() << std::endl;
}
catch (...)
{
std::wcout << "Unknown exception" << std::endl;
}
return 0;
}
