您好我想将 JSONArray 转换为 Base64 格式，并希望将其发布到服务器上 我正在给一个arraylist作为json数组的参数，如此
JsonArray jArray = new JSONArray(<<ArrayList NAME>>);

我试过这个，
String Encoded = new String(Base64.decode(jArray.toString(), Base64.DEFAULT));
以及在服务器上发布jsonarray的代码，
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(<<URL WHERE DATA IS POSTING>>);
try{
String Encoded = Base64.encodeToString((jArray.toString()).getBytes(), Base64.DEFAULT);
String param = Encoded;
sBuilder = new StringBuilder();
List<NameValuePair> list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("var1", param));
Log.d("Params", ""+list);
Log.d("Encoded Format", ""+Encoded);
decoded = Base64.decode(param, Base64.DEFAULT);
Log.d("decoded byte Format", ""+Encoded);
Log.d("Decoded Format", ""+Decoded);
httpPost.setEntity(new UrlEncodedFormEntity(list));
HttpResponse httpResponse = httpClient.execute(httpPost);
Log.d("HttpResponse", ""+httpResponse);
StatusLine statusLine = httpResponse.getStatusLine();
int i = statusLine.getStatusCode();
if(i == 200){
BufferedReader reader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));
String data = reader.readLine();
sBuilder.append(data);
}
Log.d("Getting JSON","JSON data DownLoad"+ "\n" + sBuilder);
isMailSent = true;
}catch(Exception e){
}
并且作为结果我得到了编码的字符串日志，例如： -
12-11 16:06:46.785: D/Encoded Format(6514): WyJ7cHJldmlvdXNfY29zdD1ObyBQcmV2aW91cyBDb3N0IEF2YWlsYWJsZSwgaWQ9QjAwUERCS0FU

等等。
我希望这些编码的字符串成为一个字符串，但它会编码成部分。 谢谢！
答案 0 :(得分：0)
方法Base63.decode()用于解码，即 base64 - ＆gt;表示JSONArray的字符串
你想要逆向转换。请改用Base64.encode方法
