本文介绍了在使用AMF连接发送Flex消息时,获取不支持的AMF版本错误的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
ClientStatusException $ b $我试图使用AMF连接API发送AMF消息,但得到如下所示的错误。 b消息:不支持的AMF版本
为此,我正在使用blazeds-core-4.0.1.21287.jar
以下是我的代码。
String url =https ://10.222.73.251:9443 /的vSphere的客户端/#;
尝试{
amfConnection.connect(url);
System.out.println(amfConnection.getUrl());
} catch(ClientStatusException cse){
System.out.println(Error connecting url:+ cse);
return;
try {
amfConnection.addHttpRequestHeader(Cookie,
6250CED9FBC7D5894B79973DEC1503A6);
amfConnection.addHttpRequestHeader(Content-type,
application / x-amf);
amfConnection.setAmfTrace(new AmfTrace());
//amfConnection.setObjectEncoding(3);
System.out.println(amfConnection.getObjectEncoding());
CommandMessage cmsg = new CommandMessage();
cmsg.setOperation(CommandMessage.CLIENT_PING_OPERATION);
cmsg.setMessageId(UUIDUtils.createUUID());
cmsg.setHeader(Message.FLEX_CLIENT_ID_HEADER,706E5399-D81A-11C8-11F7-BE5F1940632E);
cmsg.setHeader(Message.ENDPOINT_HEADER,amf);
AcknowledgeMessage ack =(AcknowledgeMessage)amfConnection.call(null,cmsg);
任何帮助表示赞赏。 :)
解决方案
我有同样的问题。原因是服务器期望一个独立的AMF数据包。
请参阅
意味着你需要在普通的AMF消息之前添加以下字节:
byte [] header =
{0x00,0x03,//版本
0x00,0x00,//要跟随的头部类型结构的数量(无)
0x00,0x01,//消息类型的nr (一)
0x00,0x04,// target-uri-length
0x6e,0x75,0x6c,0x6c,// target urinull
0x00,0x04, //响应uri长度
0x6e,0x75,0x6c,0x6c,//响应urinull
??,??,??,?? //正常消息的长度,32位
};
I am trying to send AMF message using AMF Connection API but getting following error as shown below.
ClientStatusException
message: Unsupported AMF version
I am using blazeds-core-4.0.1.21287.jar for this purpose.
Following is my code.
String url = "https://10.222.73.251:9443/vsphere-client/#";
try {
amfConnection.connect(url);
System.out.println(amfConnection.getUrl());
} catch (ClientStatusException cse) {
System.out.println("Error connecting url: " + cse);
return;
}
try {
amfConnection.addHttpRequestHeader("Cookie",
"6250CED9FBC7D5894B79973DEC1503A6");
amfConnection.addHttpRequestHeader("Content-type",
"application/x-amf");
amfConnection.setAmfTrace(new AmfTrace());
//amfConnection.setObjectEncoding(3);
System.out.println(amfConnection.getObjectEncoding());
CommandMessage cmsg = new CommandMessage();
cmsg.setOperation(CommandMessage.CLIENT_PING_OPERATION);
cmsg.setMessageId(UUIDUtils.createUUID());
cmsg.setHeader(Message.FLEX_CLIENT_ID_HEADER, "706E5399-D81A-11C8-11F7-BE5F1940632E");
cmsg.setHeader(Message.ENDPOINT_HEADER, "amf");
AcknowledgeMessage ack = (AcknowledgeMessage)amfConnection.call(null, cmsg);
Any help is appreciated. :)
解决方案
I had the same problem. The cause was that the server expected a "self-contained AMF packet".
See https://en.wikipedia.org/wiki/Action_Message_Format#AMF_self-contained_packet
This basically means that you need to add the following bytes in front of the "normal" AMF message:
byte[] header =
{ 0x00, 0x03, // version
0x00, 0x00, // nr of "header-type-structures" to follow (none)
0x00, 0x01, // nr of "message-type-structures" to follow (one)
0x00, 0x04, // target-uri-length
0x6e, 0x75, 0x6c, 0x6c, // target uri "null"
0x00, 0x04, // response uri length
0x6e, 0x75, 0x6c, 0x6c, // response uri "null"
??, ??, ??, ?? // the length of the "normal" message, 32 bits
};
