Between data transmission；
Specifically include following steps：
Step 1：Spatial data request Agen1, which generates a spatial data transmission, to be asked and an xml document is written
Example1.xml, it is writeable then to change document properties；Start a watcher thread, judges whether the document attribute is only
It reads；
When spatial data request Agent1 obtains a file transmission request character string, by example1.xml files
Attribute changes are writeable, then call " writing XML methods " that transmission request character string is written in XML file, while by type
The value of node is changed to " C# " (indicating that C# programs are modified XML file), then starts a thread and monitors, when
It when the attribute of example1.xml files is writeable, calls " reading XML document method "；
Step 2：Whether the example1.xml document properties in spatial data transmission Agent1 judgment steps 1 are changed to can
It writes, then reads spatial data transmission request content in this way, and spatial data transmission request is sent to response by cloud platform
The spatial data transmission Agent2 at end；
One " reading XML behaviors " is designed in spatial data transmission Agent1, judges example.xml texts every 100ms
The attribute of part reads data transfer request content, on this basis if type nodes if this document is writeable attribute
Value is " C# " and the value of queryStr nodes is not that sky then starts " sending message behavior ", which is asked to put down by cloud
Platform is sent to the data transmission Agent2 of the other end；
Step 3：The spatial data transmission request content of reception is written one by the spatial data transmission Agent2 of responder
Xml document example2.xml, and example2.xml document properties are rewritten as writeable；
There are one the behavior of " receiving message " in the spatial data transmission Agent2 of responder, function is to receive data to pass
The message that defeated Agent1 is sent, normal condition are constantly in blocked state, wait message to be received.Once receiving message, the behavior
Start " writing XML behaviors " first, the attribute of example2.xml files is changed to writeable, then will come from request of data Agent1
File transmission request character string write in specified XML file, and by the value of type nodes be set as " Java " (indicate Java journeys
Sequence is modified XML file).Then start a watcher thread, when example1.xm2 files attribute be can
It when writing, calls " reading XML document method "；
