GCDWebServer 介绍
由swisspol提供的开源库GCDWebServer是一个轻量的HTTP server，它基于 GCD 并可用于 OS X &
iOS，该库还实现了基于web的文件上传以及 WebDAV server等扩展功能。
使用方法：
#import "GCDWebServer.h"
#import "GCDWebServerDataResponse.h"
static GCDWebServer* _webServer = nil; // This should really be an ivar of your application's delegate class
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
// Create server
_webServer = [[GCDWebServer alloc] init];
// Add a handler to respond to GET requests on any URL
[_webServer addDefaultHandlerForMethod:@"GET"
requestClass:[GCDWebServerRequest class]
processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
return [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
}];
// Start server on port 8080
[_webServer startWithPort:8080 bonjourName:nil];
return YES;
}
