""" Method invocation: |
|
34
|
|
|
A remote method is invoked by sending a request to a remote service. |
|
35
|
|
|
The request must be a single object serialized using JSON. |
|
36
|
|
|
It has three properties: |
|
37
|
|
|
- service: A String containing the name of the method to be invoked. |
|
38
|
|
|
- params: A dict of objects to pass as arguments to the method. |
|
39
|
|

- id: The request id. This can be of any type. It is used to match |
|
40
|
|

the response with the request that it is replying to. |
|
41
|
|
|
Response: |
|
42

When the method invocation completes, the service replies with a |
|
43
|
|
|
response. The response is a single object serialized using JSON. |
|
44
|
|
|
It has three properties: |
|
45
|
|
|
- result: The Object returned by the invoked method. Null in case |
|
46
|
|
|
there was an error invoking the method. |
|
47
|
|
|
- error: An Error object if there was an error invoking the method. |
|
48
|
|
|
Null if there was no error. |
|
49
|
|

- id: The same id as the request it is responding to. |
