好久沒更新文章了，近期在做通訊錄上傳，把它分享出來，送給需要的朋友。

寫了一個通訊錄工具類，直接放代碼吧，關鍵位置通過註釋來解釋。

這個工具類包含通訊錄獲取，加密，然後上傳操作。看不懂的可以留言

　　使用方法就是：

ContactReader.onContactURLReport();//上報通訊錄信息即可
上面解密後的數據日誌為(聲明：通訊錄數據都是假數據，如有雷同，純屬巧合，可聯系我刪除)：

原數據是上面這樣，中間是有點的，下面這個被編輯器去掉了

　獲取通訊錄需要權限，記著提前申請：

Manifest.permission.READ_CONTACTS

----------附上base64位加密後面附帶的參數解釋----

CRLF 這個參數看起來比較眼熟，它就是Win風格的換行符，意思就是使用CR LF這一對作為一行的結尾而不是Unix風格的LF

DEFAULT 這個參數是默認，使用默認的方法來加密

NO_PADDING 這個參數是略去加密字符串最後的”=”

NO_WRAP 這個參數意思是略去所有的換行符（設置後CRLF就沒用了）

URL_SAFE 這個參數意思是加密時不使用對URL和文件名有特殊意義的字符來作為加密字符，具體就是以-和_取代+和/
