iOS 利用CocoaHttpServer搭建手机本地服务器

1、首先导入第三方

目录结构（删除了Samples文件夹）

导入库时选择create groups

成功导入后会报错

Multiple commands produce '/Users/xxx/Library/Developer/Xcode/DerivedData/3D_Touch-hkkuoykjtawrqcdogfwpdukvryhl/Build/Products/Debug-iphoneos/3D Touch.app/About.txt':
1) Target '3D Touch' (project '3D Touch') has copy command from '/Users/xxx/Desktop/CocoaHTTPServer-master/Vendor/CocoaAsyncSocket/About.txt' to '/Users/xxx/Library/Developer/Xcode/DerivedData/3D_Touch-hkkuoykjtawrqcdogfwpdukvryhl/Build/Products/Debug-iphoneos/3D Touch.app/About.txt'
2) Target '3D Touch' (project '3D Touch') has copy command from '/Users/xxx/Desktop/CocoaHTTPServer-master/Vendor/CocoaLumberjack/About.txt' to '/Users/xxx/Library/Developer/Xcode/DerivedData/3D_Touch-hkkuoykjtawrqcdogfwpdukvryhl/Build/Products/Debug-iphoneos/3D Touch.app/About.txt'

因为这两个文件有重复，才会报错的，将两个文件删除即可。

2、在appdelegate文件中开启服务，获取端口号

引入头文件，并定义两个全局变量

#import "HTTPServer.h"
#define webPath [[NSBundle mainBundle]pathForResource:@"content.html" ofType:nil]

@property (nonatomic) HTTPServer *localHttpServer;
@property (nonatomic) NSString *port;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 搭建本地服务器并启动
    [self setupLocalHttpServer];
    
    //导航
    self.window.rootViewController = [[UINavigationController alloc]initWithRootViewController:[ViewController new]];
    
    return YES;
}

#pragma mark - HTTP Server 搭建本地服务器并启动
- (void)setupLocalHttpServer {
    _localHttpServer = [[HTTPServer alloc] init];
    [_localHttpServer setType:@"_http.tcp"];
    
    NSFileManager *fileManager = [[NSFileManager alloc] init];
    NSLog(@"%@",webPath);
    
    if (![fileManager fileExistsAtPath:webPath]) {
        NSLog(@"File path error!");
    } else {
        NSString *webLocalPath = webPath;
        [_localHttpServer setDocumentRoot:webLocalPath];
        NSLog(@"webLocalPath:%@",webLocalPath);
        [self startServer];
    }
}

- (void)startServer {
    NSError *error;
    if ([_localHttpServer start:&error]) {
        NSLog(@"Started HTTP Server on port %hu", [_localHttpServer listeningPort]);
        self.port = [NSString stringWithFormat:@"%d",[_localHttpServer listeningPort]];
        //保存端口号，在调用的时候使用
            NSUserDefaults *accountDefaults = [NSUserDefaults standardUserDefaults];
                 [accountDefaults setObject:self.port forKey:@"webPort"];
                [accountDefaults synchronize];
    } else {
        NSLog(@"Error starting HTTP Server: %@", error);
    }
}

3、在UIViewController中加载webView
注意：链接必须是http://locoahost:端口号

#import 

@property (nonatomic) WKWebView *webView;

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];

    self.webView = [[WKWebView alloc] init];
    //获取端口号，加载本地服务器html
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://localhost:%@", [userDefaults objectForKey:@"webPort"]]];
    NSLog(@"%@",[NSString stringWithFormat:@"http://localhost:%@", [userDefaults objectForKey:@"webPort"]]);
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [self.webView loadRequest:request];
}
