Converting a json value that keeps changing to int in c++ - c++

Question

Okay so i get this JSON object from my client:
{"command":"BrugerIndtastTF","brugerT":"\"10\"","brugerF":"\"20\""}
Then i need to use the int value from "brugerT", but as you can see it has "\"10\"" around it. When i code this in javascript i dont get this problem. Is there a way to only use the part of "brugerT" that says 10?
the code where *temp only should print the int value 10:
socket_->hub_.onMessage([this](
uWS::WebSocket<uWS::SERVER> *ws,
char* message,
size_t length,
uWS::OpCode opCode
)
{
std::string data = std::string(message,length);
std::cout << "web::Server:\t Data received: " << data << std::endl;
// handle manual settings
std::cout << "Web::Server:\t Received request: manual. Redirecting message." << std::endl;
json test1 = json::parse(data);
auto test2 = test1.json::find("command");
std::cout << "Web::Server:\t Test 1" << test1 << std::endl;
std::cout << "Web::Server:\t Test 2" << *test2 << std::endl;
if (*test2 =="BrugerIndtastTF")
{
std::cout<<"Web::Server:\t BrugerIndtastTF modtaget" << std::endl;
auto temp= test1.json::find("brugerT");
auto humi= test1.json::find("brugerF");
std::cout << "Web::Server:\t temp: " << *temp << "humi: " << *humi << std::endl;
}
});
EDIT:
Here you can see the terminal
it should just say: temp: 10 humi: 20

You can try to get the string value of brugerT and strip the \" out of the string and then convert the resulting string into a int with stoi. You could even use a regular expression to find the integer inside the string and let that library figure out what is the best matching method. A regular expression for that would be something like: ([0-9]+)
ps string literal type 6 might be of some use when manually filtering out \"
#include <iostream>
#include <regex>
#include <string>
using namespace std;
int main() {
string inputStr(R"("\"10\"")");
regex matchStr(R"(([0-9]+))");
auto matchesBegin = sregex_iterator(inputStr.begin(), inputStr.end(), matchStr);
auto matchesEnd = sregex_iterator();
for (sregex_iterator i = matchesBegin; i != matchesEnd; ++i) {
cout << i->str() << endl;
}
return 0;
}
