Android:解決client從server上擷取資料亂碼的方法

標籤：

向server發送HTTP請求。接收到的JSON包為response，用String content = EntityUtils.toString(response.getEntity(),"utf-8");解碼還是出現了中文亂碼，在後面加了

        String name = new String(response.getBytes("iso-8859-1"), "UTF-8");  

也無濟於事。

想到server好像是用URLENCODER編了碼的。懷著試一試的態度在return後面加了條URLDecoder.decode(content,"utf-8");果然有效！

只是還是不太明確URLDecoder.decode(content,"utf-8")和EntityUtils.toString(response.getEntity(),"utf-8")在解碼的時候有什麼差別。以下是網路端的代碼：
