if (u.equals(otherUser)) {
message = message.replace("\"offer\"", "\"answer\"");
message = message.replace("a=crypto:0 AES_CM_128_HMAC_SHA1_32",
"a=xrypto:0 AES_CM_128_HMAC_SHA1_32");
message = message.replace("a=ice-options:google-ice\\r\\n", "");
}
//向对方发送连接数据
WebRTCMessageInboundPool.sendMessage(otherUser, message);
}
}
可以新建一个web项目部署一下试试。
