Xmpp遇到的问题：openfire中发送某些特殊字符会断开xmpp连接的问题(3)

[java] view
plaincopyprint?





protected char more() throws IOException, XmlPullParserException {

final char codePoint = super.more(); // note - this does NOT return a codepoint now, but simply a (single byte) character!

if ((codePoint == 0x0) || // 0x0 is not allowed, but flash clients insist on sending this as the very first character of a stream. We should stop allowing this codepoint after the first byte has been parsed.

(codePoint == 0x9) ||

(codePoint == 0xA) ||

(codePoint == 0xD) ||

((codePoint >= 0x20) && (codePoint <= 0xD7FF)) ||

((codePoint >= 0xE000) && (codePoint <= 0xFFFD)) ||

((codePoint >= 0x10000) && (codePoint <= 0x10FFFF))) {

return codePoint;

}



throw new XmlPullParserException("Illegal XML character: " + Integer.parseInt(codePoint+"", 16));

}

由于openfire 对emoj表情的过滤导致，链接断开；因此稍微对源码做修改
