好久没更新文章了，近期在做通讯录上传，把它分享出来，送给需要的朋友。

写了一个通讯录工具类，直接放代码吧，关键位置通过注释来解释。

这个工具类包含通讯录获取，加密，然后上传操作。看不懂的可以留言

使用方法就是：

ContactReader.onContactURLReport();//上报通讯录信息即可

上面解密后的数据日志为(声明：通讯录数据都是假数据，如有雷同，纯属巧合，可联系我删除)：

原数据是上面这样，中间是有点的，下面这个被编辑器去掉了

获取通讯录需要权限，记着提前申请：

Manifest.permission.READ_CONTACTS

----------附上base64位加密后面附带的参数解释----

CRLF 这个参数看起来比较眼熟，它就是Win风格的换行符，意思就是使用CR LF这一对作为一行的结尾而不是Unix风格的LF

DEFAULT 这个参数是默认，使用默认的方法来加密

NO_PADDING 这个参数是略去加密字符串最后的”=”

NO_WRAP 这个参数意思是略去所有的换行符(设置后CRLF就没用了)

URL_SAFE 这个参数意思是加密时不使用对URL和文件名有特殊意义的字符来作为加密字符，具体就是以-和_取代+和/
