CPPRest SDK making HTTP request to Server - c++

Question

during CPPRest SDK (2.8) testing, I initialized an HTTP Request simulating user login to the local server, I am expecting a JSON string to be returned indicating if login succeed. here is the code I wrote.
void printJSON(json::value v)
{
if (!v.is_null()){
// Loop over each element in the object
for (auto iter = v.as_object().cbegin(); iter != v.as_object().cend(); ++iter){
const string &key = iter->first;
const json::value &value = iter->second;
if (value.is_object() || value.is_array()){
if(key.size() != 0){
std::wcout << "Parent: " << key.c_str() << std::endl;
}
printJSON(value);
if(key.size() != 0){
std::wcout << "End of Parent: " << key.c_str() << std::endl;
}
}else{
std::wcout << "Key: " << key.c_str() << ", Value: " << value.to_string().c_str() << std::endl;
}
}
}
}
void login(){
http_client client("http://localhost:8080/user");
http_request request(methods::POST);
request.headers().add("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
request.headers().add("Content-Length", "100");
request.headers().add("Host", "testhost.com");
request.headers().add("X-Requested-With", "XMLHttpRequest");
request.set_body("u_id=test_admin&pwd=123456789");
pplx::task<void> task = client.request(request)
.then([](http_response response)-> pplx::task<json::value>{
if(response.status_code() == status_codes::OK){
return response.extract_json();
} else {
return pplx::task_from_result(json::value());
};})
.then([](pplx::task<json::value> previousTask){
try{
const json::value & v = previousTask.get();
printJSON(v);
} catch(const http_exception &e){
std::cout<<e.what()<<std::endl;
}
});
try{
task.wait();
} catch(std::exception &e){
std::cout<<e.what()<<std::endl;
}
}
When I run this code, nothing happened, it seems request never reaches to the Server which has been tested using JSP, So I am pretty sure something went wrong in my code. please help, thanks

Vague.
If you're saying that the request is not reaching the server, there might be a problem with the listener at the time you executed this code.
Your request format is correct and running, you may try to wrap the body (u_id, pwd) into a json, and see if it works.
The bottomline is debugging or sharing your server code would probably help clarify things a bit more.
