// 2.初始化请求参数

NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
[dict setObject:imageData forKey:@"images"];

NSURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:nil parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    // 上传新获得的图片文件
    [formData appendPartWithFileData:imageData name:@"imgs_file" fileName:@"hao.png" mimeType:@"image/png"];
}];


// 发送请求上传文件
AFHTTPRequestOperation *operation = [client HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"失败");
}];

[operation start];

可以看下workerman(一个高性能PHP socket服务器框架)，里面有个例子是接收客户端传输文件的。
