IOS利用CocoaHttpServer搭建手机本地服务器

这篇文章主要介绍了IOS利用CocoaHttpServer搭建手机本地服务器的步骤，帮助大家更好的理解和学习使用ios开发，感兴趣的朋友可以了解下

缘起

今天用暴风影音看视频，然后发现它有个功能，wifi传片，感觉挺有意思，然后就上网查了下相关内容。

原理

使用CocoaHTTPServer框架，在iOS端建立一个本地服务器，只要电脑和手机连入同一热点或者说网络，就可以实现通过电脑浏览器访问iOS服务器的页面，利用POST实现文件的上传。

实现

1.下载CocoaHTTPServer

2.导入CocoaHTTPServer-master目录下的Core文件夹

3.导入Samples/SimpleFileUploadServer目录下的MyHTTPConnection类文件和web文件夹

4.导入Vendor目录下的CocoaAsyncSocket、CocoaLumberjack文件夹

5.打开MyHTTPConnection.m文件，根据标记 #pragma mark multipart form data parser delegate 跳转或者直接找到139行的 *- (void) processStartOfPartWithHeader:(MultipartMessageHeader ) header 方法，把第151行的uploadDirPath改为

				?

									NSString *uploadDirPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];

这个路径是上传文件的存储路径

6.在适当的地方配置server启动。这里以AppDelegate为例

				?

									#import "AppDelegate.h"

									#import <ifaddrs.h>

									#import <arpa/inet.h>

									#import "HTTPServer.h"

									#import "DDLog.h"

									#import "DDTTYLogger.h"

									#import "MyHTTPConnection.h"

									@interface AppDelegate ()

									@property (nonatomic, strong) HTTPServer * httpServer;

									@end

									@implementation AppDelegate

									- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

									    _httpServer = [[HTTPServer alloc] init];

									    [_httpServer setPort:1234];

									    [_httpServer setType:@"_http._tcp."];

									    // webPath是server搜寻HTML等文件的路径

									    NSString * webPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"web"];

									    [_httpServer setDocumentRoot:webPath];

									    [_httpServer setConnectionClass:[MyHTTPConnection class]];

									    NSError *err;

									    if ([_httpServer start:&err]) {

									        NSLog(@"port %hu",[_httpServer listeningPort]);

									    }else{

									        NSLog(@"%@",err);

									    }

									    NSString *ipStr = [self getIpAddresses];

									    NSLog(@"ip地址 %@", ipStr);

									    return YES;

									}

									- (NSString *)getIpAddresses{

									    NSString *address = @"error";

									    struct ifaddrs *interfaces = NULL;

									    struct ifaddrs *temp_addr = NULL;

									    int success = 0;

									    // retrieve the current interfaces - returns 0 on success

									    success = getifaddrs(&interfaces);

									    if (success == 0)

									    {

									        // Loop through linked list of interfaces

									        temp_addr = interfaces;

									        while(temp_addr != NULL)

									        {

									            if(temp_addr->ifa_addr->sa_family == AF_INET)

									            {

									                // Check if interface is en0 which is the wifi connection on the iPhone

									                if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"])

									                {

									                    // Get NSString from C String

									                    address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];

									                }

									            }

									            temp_addr = temp_addr->ifa_next;

									        }

									    }

									    // Free memory

									    freeifaddrs(interfaces);

									    return address;

									}
