简介
目前一些应用里有用到在Iphone上架设http服务器，其主要用在以下几个方面
- 当需要在iphone本地架设一个小型http网站，供用户来使用。
- 或者希望通过自己的应用把相应的文件导入到电脑里，例如：目前大多数视频应用，把电脑上的视频导入到本应用。(必须在同一WIFI)
- 预加载视频。在浏览网上视频时候，在用到hls等视频切片技术的视频源时候，可以在本地架设一个http服务器预下载后边的视频，进行预加载，以达到视频播放流畅。
在iOS上，目前推荐使用CocoaHTTPServer开源框架。
CocoaHTTPServer官方介绍
CocoaHTTPServer is a small, lightweight, embeddable HTTP server for Mac OS X or iOS applications.
Sometimes developers need an embedded HTTP server in their app.
Perhaps it's a server application with remote monitoring.
Or perhaps it's a desktop application using HTTP for the communication backend.
Or perhaps it's an iOS app providing over-the-air access to documents.
Whatever your reason, CocoaHTTPServer can get the job done. It provides:
Built in support for bonjour broadcasting
IPv4 and IPv6 support
Asynchronous networking using GCD and standard sockets
Password protection support
SSL/TLS encryption support
Extremely FAST and memory efficient
Extremely scalable (built entirely upon GCD)
Heavily commented code
Very easily extensible
WebDAV is supported too!

用法
以在本地创建http web为例
在官网下载源码工程
这里使用的是一个小forkcocoa-web-resource
-
Core文件夹架设http服务器Core 核心类 -
Extensions 文件夹WebDAV实现类 -
Sample 文件夹CocoaHTTPServer基本使用 -
Vendor第三方日志类
创建工程
创建一个名为iPhoneLocalHttpServer的Demo工程
引入库
加载资源

定义
#import "HTTPServer.h"
interface ViewController ()<UIWebViewDelegate,WebFileResourceDelegate>
{
HTTPServer *httpServer;
UIWebView *mWebView;//测试webview
UILabel *urlLabel;//显示ip端口的
NSMutableArray *fileList;
}
实现
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
urlLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 20, [UIScreen mainScreen].bounds.size.width, 25)];
[self.view addSubview:urlLabel];
// set up the http server
httpServer = [[HTTPServer alloc] init];
[httpServer setType:@"_http._tcp."];
[httpServer setPort:8088];
[httpServer setName:@"iPhoneLocalHttpServer"];
[httpServer setupBuiltInDocroot];
httpServer.fileResourceDelegate = self;
NSError *error = nil;
BOOL serverIsRunning = [httpServer start:&error];
if(!serverIsRunning)
{
NSLog(@"Error starting HTTP Server: %@", error);
}
[urlLabel setText:[NSString stringWithFormat:@"http://%@:%d", [httpServer hostName], [httpServer port]]];
mWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 64, urlLabel.frame.size.width, [UIScreen mainScreen].bounds.size.height - 64)];
mWebView.delegate = self;
mWebView.scalesPageToFit = YES;
[self.view addSubview:mWebView];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://%@:%d", @"127.0.0.1", [httpServer port]]]];
[mWebView loadRequest:request];
});
}
模拟器运行:
safari打开
使用模拟器safari打开127.0.0.1:8088（真机上不行，还不知道原因）
iOS http设置
-
在Filter中搜索Info.plist，选择Info.plist进行编辑
-
按照上面提到的方式添加信息，正确的修改会看到下图这个样子，注意类型NSAppTransportSecurity为Dictionary，NSAllowsArbitraryLoads为Boolean，复制粘贴的时候，不要多了空格，segment fault 页面上直接复制，经常会多一个出空格！
