IOS开发教程之put上传文件的服务器的配置及实例分享

    NSString *authBase64 = [NSString stringWithFormat:@"Basic %@",authStr];
    //转换成第三部
    [request setValue:authBase64 forHTTPHeaderField:@"Authorization"];

    //3，session
      //1>.创建会话机制
    NSURLSessionConfiguration *config = [NSURLSessionConfigurationdefaultSessionConfiguration];
  NSURLSession *session =  [NSURLSessionsessionWithConfiguration:config delegate:selfdelegateQueue:[[NSOperationQueuealloc] init]];

    //2> 上传任务
    //上传的文件的路径
    NSURL *fileUrl =   [[NSBundle mainBundle] URLForResource:@"01.Post提交用户隐私数据&MD5加密.mp4" withExtension:nil];
    [[session uploadTaskWithRequest:request fromFile:fileUrl] resume];

//   这是不用下载进度条的方法。 
//    NSURLSessionUploadTask *task = [session uploadTaskWithRequest:request fromFile:fileUrl completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//        
//        //把二进制数据转换成字符串
//      NSString *str =  [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
//        NSLog(@"str = %@",str);
//    }];
//
