以上代碼是我修改過的代碼，不會出現亂碼了，下面和大家分享下解決這個問題的心得體會。

問題描述：因為項目初期一直是支持英文的，所以這塊也沒考慮過中文或者其他國家的文字會出現亂碼的情況，不巧遇到一個越南客戶，越南文出現了亂碼。

排查問題，客戶端和服務器端都已經設置了UTF-8的編碼模式，但是服務器端收到的Android端的備份文件還是亂碼，但是IOS端確是正常的，有點迷茫之下開始查找解決方案。

Android和ios同時打印Http請求的頭部，發現問題所在：

Andorid  :  content-type:application/x-www-form-urlencoded;
IOS  :  content-type:application/x-www-form-urlencoded; charset=utf-8;

 

OK.找到問題解決之即可。

在Android客戶端Post請求的時候加上：postUploadSermonBackup.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
