IOS利用CocoaHttpServer搭建手机本地服务器
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 interfacestemp_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 iPhoneif([[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;}
7.运行后,控制台会打印出端口号和ip,在电脑端浏览器里输入ip+端口号访问即可,如果成功的话会看到如下界面:
8.如果上传成功,网页上会出现上传的文件名,可以在沙盒里验证文件是否上传成功
