静态文件服务器在日常生活中很常用！
本文尝试使用cpp-httplib来搭建一个静态文件服务器
官方文档中关于静态服务器的说明：
// Mount / to ./www directory auto ret = svr.set_mount_point("/", "./www"); if (!ret) { // The specified base directory doesn't exist... } // Mount /public to ./www directory ret = svr.set_mount_point("/public", "./www"); // Mount /public to ./www1 and ./www2 directories ret = svr.set_mount_point("/public", "./www1"); // 1st order to search ret = svr.set_mount_point("/public", "./www2"); // 2nd order to search // Remove mount / ret = svr.remove_mount_point("/"); // Remove mount /public ret = svr.remove_mount_point("/public");
官方已经内置的MIME类型：
自定义MIME类型：
// User defined file extension and MIME type mappings svr.set_file_extension_and_mimetype_mapping("cc", "text/x-c"); svr.set_file_extension_and_mimetype_mapping("cpp", "text/x-c"); svr.set_file_extension_and_mimetype_mapping("hh", "text/x-h");
为了方便省事，直接在上篇文章中的Qt程序中进行更改。
代码如下：
#include <httplib.h> #include <iostream> using namespace httplib; void wuhan(const Request &req, Response &res) { printf("httplib server recv a req: %s ", req.path.c_str() ); res.set_content("<html> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <h1> 武汉, 加油！</h1></html>", "text/html"); res.status = 200; } int main(void) { Server svr; svr.set_base_dir("./"); /// Static file server // Mount / to ./www directory svr.set_file_extension_and_mimetype_mapping("cc", "text/x-c"); svr.set_file_extension_and_mimetype_mapping("cpp", "text/x-c"); svr.set_file_extension_and_mimetype_mapping("hh", "text/x-h"); svr.set_file_extension_and_mimetype_mapping("h", "text/x-h"); svr.set_file_extension_and_mimetype_mapping("mp3", "audio/mpeg"); svr.set_file_extension_and_mimetype_mapping("mp4", "video/mpeg"); svr.set_file_extension_and_mimetype_mapping("avi", "video/x-msvideo"); auto ret = svr.set_mount_point("/", "./www"); if (!ret) { // The specified base directory doesn't exist... std::cout << "The specified base directory doesn't exist..." << std::endl; } /// Get svr.Get("/wuhan", wuhan); svr.Get("/hi", [](const Request& req, Response& res) { res.set_content("Hello World!", "text/plain"); }); svr.Get(R"(/numbers/(d+))", [&](const Request& req, Response& res) { auto numbers = req.matches[1]; res.set_content(numbers, "text/plain"); }); svr.Get("/body-header-param", [](const Request& req, Response& res) { if (req.has_header("Content-Length")) { auto val = req.get_header_value("Content-Length"); } if (req.has_param("key")) { auto val = req.get_param_value("key"); } res.set_content(req.body, "text/plain"); }); svr.Get("/stop", [&](const Request& req, Response& res) { svr.stop(); }); /// listen svr.listen("localhost", 1234); }
构建运行，前提需要在生成目录下放置好静态资源，我的目录如下：
