我正在使用BlazeDS java client从 this page 获取信息。 此页面中间有一个表单,当您选择类型时,按钮上的位置组合会更新。
我正在尝试使用 BlazeDS 在 java 中获取这些值。 我一直用Charles web proxy进行调试,这是来自 the request 的屏幕截图和 the response :
到目前为止我的代码如下:
// Create the AMF connection.
AMFConnection amfConnection = new AMFConnection();
// Connect to the remote url.
String url = "http://orlandoinfo.com/flex2gateway/";
try
{
amfConnection.connect(url);
}
catch (ClientStatusException cse)
{
System.out.println(cse);
return;
}
// Make a remoting call and retrieve the result.
try
{
// amfConnection.registerAlias("flex.messaging.io.ArrayCollection", "flex.messaging.io.ArrayCollection");
amfConnection.call("ColdFusion.getLocations", new Object[] {"consumer", "attractions", "ATTR"});
}
catch (ClientStatusException cse)
{
System.out.println(cse);
}
catch (ServerStatusException sse)
{
System.out.println(sse);
}
// Close the connection.
amfConnection.close();
当我运行它时,我得到:
ServerStatusException
data: ASObject(15401342){message=Unable to find source to invoke, rootCause=null, details=null, code=Server.Processing}
HttpResponseInfo: HttpResponseInfo
code: 200
message: OK
谁能发现问题所在吗?
感谢您的阅读!

我最终使用了 Charles Web Proxy。嗅探 AMF 参数并使用 -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888
我比较了这两个调用并修改为看起来相似。 工作代码如下所示:
String url = "http://www.theGateWayurl.com";
// Generates the connection to the amf gateway.
AMFConnection amfConnection = new AMFConnection();
// Must register the class that this library will use to load the
// AMF object information.
// The library will read AMF object variables and use setters from
// the java bean stated in this line.
AMFConnection.registerAlias("", new LabelData().getClass().getName());
try {
// Do the connection.
amfConnection.connect(url);
// This page requires a certain headers to function.
// The Content-type is used to sniff with Charles Web Proxy.
amfConnection.addHttpRequestHeader("Content-type", "application/x-amf");
// The Referer is used by the webpage to allow gathering information.
amfConnection.addHttpRequestHeader("Referer", "http://orlandoinfo.com/ws/b2c/sitesearch/customtags/comSearch.swf");
// The rest of the HTTP POST sent by this library is wrapped
// inside a RemotingMessage.
// Prepare the msg to send.
RemotingMessage msg = new RemotingMessage();
// The method called in the server.
msg.setOperation("getLocations");
// Where the request came from. Similar to referer.
msg.setSource("ws.b2c.sitesearch.components.myService");
// The destination is a needed parameter.
msg.setDestination("ColdFusion");
// Create the body with the parameters needed to call the
// operation set with setOperation()
msg.setBody(new Object[] {"consumer", "attractions"});
// This is needed but not used.
msg.setMessageId("xxxxxxxxxx");
// Send the msg.
AcknowledgeMessage reply = (AcknowledgeMessage) amfConnection.call("null", msg);
// Parse the reply from the server.
ArrayCollection body = (ArrayCollection) reply.getBody();
for (Object obj : body) {
LabelData location = (LabelData) obj;
// Do something with the info.
}
} catch (ClientStatusException cse) {
// Do something with the exception.
} catch (ServerStatusException sse) {
// Do something with the exception.
} finally {
amfConnection.close();
}
LabelData 只是一个带有两个变量的 java bean:Data 和 Label。 我尝试对每一行进行注释以便更好地理解。 考虑一下 Stu 在之前关于 crossdomain.xml 的评论中提到的内容,看看您是否有权执行此类操作。
