代码中的一些key 相比如：

#define kAiAccessKey @"xxx"
#define kAliAccessSecret @"xxxx"
#define kAliBucketName @"xxx-face"
#define kAliImageURLPrefix @"https://xxx.oss-cn-hangzhou.aliyuncs.com/"
#define kAliEndPoint @"oss-cn-hangzhou.aliyuncs.com"

这些key自己去找项目经理要，或者在阿里云开发者后台里面都可以找到，就不一一解释这么多了。
使用到的地方：

            // MARK: - 上传图片至阿里云
            NSMutableArray *dataItems = [NSMutableArray new];

                [dataItems addObject:UIImageJPEGRepresentation(faceImage, 0.3)];
            }
            __block NSMutableArray *_imageUrls = [NSMutableArray new];
            dispatch_queue_t queue = dispatch_queue_create("com.Chan.uploadImageToAliyunServer.www", DISPATCH_QUEUE_CONCURRENT);

              //这里拿到的objectKeys就是图片在阿里云服务器上保存的位置地址URL，名字是用时间戳随机生成的（此处随自己意愿）
                    if (objectKeys && objectKeys.count) {
                        [_imageUrls addObject:objectKeys];
