drogon::app().forward(...) does not perform URL escaping

[Mis1eader-dev]

Describe the bug
Forwarding requests that contain spaces in the URL all fail to be resolved on the forwarded party.
After manually replacing spaces with their escaped equivalences it worked.

string path = req->path();
replaceAll(path, " ", "%20");
req->setPath(std::move(path));
drogon::app().forward(std::move(req), std::move(callback), host);

Solution
Perform URL escaping on the path before forwarding.

Alternative Solution
Have it use req->getOriginalPath() instead of req->path()

req->setPath(req->getOriginalPath());
drogon::app().forward(std::move(req), std::move(callback), host);

#include <drogon/drogon.h>
#include

void forwardRequest(const std::shared_ptrdrogon::HttpRequest &req, const std::function<void(const drogon::HttpResponsePtr &)> &callback, const std::string &host) {

req->setPath(req->getOriginalPath());


drogon::app().forward(std::move(req), std::move(callback), host);

}

int main() {

drogon::app().registerHandler("/forward", [](const drogon::HttpRequestPtr &req, std::function<void (const drogon::HttpResponsePtr &)> &&callback) {
    std::string host = "http://example.com";  
    
    
    forwardRequest(req, std::move(callback), host);
});

// Start the Drogon application
drogon::app().run();
return 0;

}
please check the code I am not understand properly but try this .

@ladaniprem the provided alternative solution does this, but I'm awaiting opinions of other maintainers as to whether we should alter request objects or alter the forward function itself.
