SDK v6.2.1 友盟分享网络图片出错

在6.2.1版本中，我在分享需要的平台的时候总是出现如下的错误

后来在文档中发现友盟明确说明如需使用网络图片，确保URL为HTTPS图片链接，

而我的基地址是以http开头的，总不能在把SDK换成老的版本吧。后来尝试过把网络图片转化为NSData也是行不通的，在最后通过直接从SDWebImage的缓存中找到需要分享的图片，要是找不到就分享本地图片。

NSString *urlKey = [[SDWebImageManager sharedManager] cacheKeyForURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",HOST_URL,shareImg]]];
    UIImage *image = [[SDImageCache sharedImageCache] imageFromDiskCacheForKey:urlKey];
    if (!image) {
        image = [UIImage imageNamed:@"login_Logo.png"];
    }

在最后附上分享的全部代码

.h中

/**
 *  弹出分享
 */
+ (void)presentSocialSnsIconSheetViewWithObject:(id)object
                                       shareURL:(NSString *)urlStr
                                      shareText:(NSString *)shareText
                                     shareTitle:(NSString *)shareTitle
                                       shareImg:(NSString *)shareImg;

.m中

+ (void)presentSocialSnsIconSheetViewWithObject:(id)object
                                       shareURL:(NSString *)urlStr
                                      shareText:(NSString *)shareText
                                     shareTitle:(NSString *)shareTitle
                                       shareImg:(NSString *)shareImg{

    //创建分享消息对象
    UMSocialMessageObject *messageObject = [UMSocialMessageObject messageObject];
    
    NSString *urlKey = [[SDWebImageManager sharedManager] cacheKeyForURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",HOST_URL,shareImg]]];
    UIImage *image = [[SDImageCache sharedImageCache] imageFromDiskCacheForKey:urlKey];
    if (!image) {
        image = [UIImage imageNamed:@"login_Logo.png"];
    }
    UMShareWebpageObject *shareObject = [UMShareWebpageObject shareObjectWithTitle:shareTitle descr:shareText thumImage:image];
    shareObject.webpageUrl = urlStr;
    messageObject.shareObject = shareObject;
    [UMSocialUIManager setPreDefinePlatforms:@[@(UMSocialPlatformType_Sina),@(UMSocialPlatformType_QQ),@(UMSocialPlatformType_Qzone),@(UMSocialPlatformType_WechatSession),@(UMSocialPlatformType_WechatTimeLine)]];
    [UMSocialUIManager showShareMenuViewInWindowWithPlatformSelectionBlock:^(UMSocialPlatformType platformType, NSDictionary *userInfo) {
        
        [[UMSocialManager defaultManager] shareToPlatform:platformType  messageObject:messageObject currentViewController:object completion:^(id result, NSError *error) {
            if (error) {
                NSLog(@"************Share fail with error %@*********",error);
            }else{
                NSLog(@"response data is %@",result);
            }
        }];
    }];

}
