Wi-Fi传输文件

SGWiFiUpload

• SGWiFiUpload使用了CocoaHttpServer创建服务器，接受并监听文件
• 使用SGHTTPConnection继承HTTPConnection修改了里面的文件储存路径，并且使用通知监听了里面的上传进度

SGHTTPConnection类

- (void) processStartOfPartWithHeader:(MultipartMessageHeader*) header 

    // 这里用于发出文件开始上传的通知
    dispatch_async(dispatch_get_main_queue(), ^{
        [[NSNotificationCenter defaultCenter] postNotificationName:SGFileUploadDidStartNotification object:@{@"fileName" : filename ?: @"File"}];
    });
    // 这里用于设置文件的保存路径，先预存一个空文件，然后进行追加写内容
    NSString *uploadDirPath = [SGWiFiUploadManager sharedManager].savePath;

SGWiFiUploadManager类

• 控制服务器开关
• 接受文件上传进度并回调出去
• 弹出上传界面

例子

   SGWiFiUploadManager *mgr = [SGWiFiUploadManager sharedManager];
    BOOL success = [mgr startHTTPServerAtPort:10086];
    if (success) {
        [mgr setFileUploadStartCallback:^(NSString *fileName, NSString *savePath) {
            NSLog(@"File %@ Upload Start", fileName);
        }];
        [mgr setFileUploadProgressCallback:^(NSString *fileName, NSString *savePath, CGFloat progress) {
            NSLog(@"File %@ on progress %f", fileName, progress);
        }];
        [mgr setFileUploadFinishCallback:^(NSString *fileName, NSString *savePath) {
            NSLog(@"File Upload Finish %@ at %@", fileName, savePath);
        }];
    }
    [mgr showWiFiPageFrontViewController:self dismiss:^{
        [mgr stopHTTPServer];
    }];
