批量替换markdown本地图片地址为七牛外链

平时用markdown写文章，直接截图粘贴非常快速，可要把本地的图片地址换成在线的，如果链接多了一一替换就比较麻烦了，所以直接用脚本批量替换，省时省力。

    #print("返回结果：%s %s %s" %(qiniu.key,qiniu.etag,qiniu.cloudfile))
    #False 只打印本地图片地址，True 将本地图片上传至七牛并替换成七牛外链 
    scanFilesInRootPath(inputRootPath,False)

使用步骤

1、修改Access Key 和 Secret Key等配置信息，如需上传本地图片并替换为七牛修改入口为scanFilesInRootPath(inputRootPath,True)

2、运行python3 QiniuUploader.py
