httplib 与 json.hpp 结合示例

1、使用POST 接口，发送 登陆 请求

客户端发送

{nlohmann::json jsonOfCollectionInfo;jsonOfCollectionInfo["user_id"] = "zhang";jsonOfCollectionInfo["password"] = "123456";httplib::Client cli(collector_server_address);auto reponse = cli.Post("/login_in", jsonOfCollectionInfo.dump(), "text/plain");
}

服务端接收

{// HTTPhttplib::Server svr_http;svr_http.Post("/login_in", [](const httplib::Request &request, httplib::Response &res){std::cout << "[" <<  __FILE__ << "][" << __LINE__ << "] recevie post msg begin" << request.body <<  std::endl;auto request = nlohmann::json::parse(request->body);...... std::cout <<  输出 request 的信息 << std::endl;.....});
}

2、使用get 接口，获取联网状态

客户端发送

httplib::Client cli("http://0.0.0.0:8188");
auto res_client = cli.Get("/get_network_status");
if(res_client == NULL)
{return false;
}
std::cout << res_client->status << std::endl;
std::cout << res_client->body << std::endl;
auto json_result = nlohmann::json::parse(res_client->body);

服务端接收

{// HTTPhttplib::Server svr_http;svr_http.Post("/get_network_status", [](const httplib::Request &request, httplib::Response &res){std::cout << "[" <<  __FILE__ << "][" << __LINE__ << "] recevie post msg begin" << request.body <<  std::endl;auto request = nlohmann::json::parse(request->body);...... std::cout <<  输出 request 的信息 << std::endl;.....});
}
