当我编码tex时,由于某种原因,它会截断一部分字符串...可能是什么问题?
DateFormat dateFormat =
new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a", Locale.ENGLISH);
Date date = new Date();
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.HOUR,+ 9);
String server_time = dateFormat.format(calendar.getTime());
String wmsAuthSign = "server_time=" + server_time + "&hash_value=U2QK9TLB55JWTZr3OKZHtg==&validminutes=120";
wmsAuthSign = "?wmsAuthSign=" + Base64.encodeToString(wmsAuthSign.getBytes(), Base64.DEFAULT);
我正在提交这样的内容:
server_time=02/18/2019 23:38:43 PM&hash_value=U2QK9TLB55JWTZr3OKZHtg==&validminutes=120
如果解码编码的文本,则会得到修剪后的结果:
server_time=02/18/2019 23:38:43 PM&hash_value=U2QK9TLB55J
答案 0 :(得分:3)
由于RFC-2045:
(5) (Soft Line Breaks) The Quoted-Printable encoding REQUIRES that encoded lines be no more than 76 characters long. If longer lines are to be encoded with the Quoted-Printable encoding, "soft" line breaks
源数据字符串:
server_time=02/18/2019 23:38:43 PM&hash_value=U2QK9TLB55JWTZr3OKZHtg==&validminutes=120
Base64编码为字符串:
c2VydmVyX3RpbWU9MDIvMTgvMjAxOSAyMzoxMjo1NiBQTSZoYXNoX3ZhbHVlPVUyUUs5VExCNTVK
V1RacjNPS1pIdGc9PSZ2YWxpZG1pbnV0ZXM9MTIw
与上面显示的完全一样:带有换行符。但是在接收方,您可能只解码第一行
c2VydmVyX3RpbWU9MDIvMTgvMjAxOSAyMzoxMjo1NiBQTSZoYXNoX3ZhbHVlPVUyUUs5VExCNTVK
即server_time=02/18/2019 23:12:21 PM&hash_value=U2QK9TLB55J
因此,不仅在第一行,还要在接收方解码整个接收到的数据。
或者您可能只将编码的Base64的第一行发送到接收方。
还要看看this的Mohammad Adil答案:
在android上,使用
Base64.NO_WRAP
代替Base64.DEFAULT
