POST Call

[sanjoy-gwtp]

error: C3688: invalid literal suffix '_method'; literal operator or literal operator template 'operator ""_method' not found

[Shravan40]

Could you please provide us whole POST method, which you are trying to compile ?

[sanjoy-gwtp]

CROW_ROUTE(app, "/add_json") .methods("POST"_method) ([](const crow::request& req){ auto x = crow::json::load(req.body); if (!x) return crow::response(400); int sum = x["a"].i()+x["b"].i(); std::ostringstream os; os << sum; return crow::response{os.str()}; });

It's the same example given in project description. And it's working fine at my machine. Please post the complete error log, with the command you are using to compile it.

@sanjoy-gwtp, it looks like you're using MSVC. Which version are using? Be sure not to have CROW_MSVC_WORKAROUND defined and to use MSVC 2013 or 2015+. I've successfully used 2015 myself.

[sanjoy-gwtp]

I find my solution.

CROW_ROUTE(app, "/add_json") .methods("POST"_method) it will be methods(crow::HTTPMethod::Post) ([](const crow::request& req){ auto x = crow::json::load(req.body); if (!x) return crow::response(400); int sum = x["a"].i()+x["b"].i(); std::ostringstream os; os << sum; return crow::response{os.str()}; });
