A) such as msgJsonOfTopicName.attrName3.attrName31, (the json node of Object type),
A new variable is converted by hash, it is assumed that is abcde.
B) such as msgJsonOfTopicName.attrName2 [0] (the json node of Array type) turns by hash
Turn to a new variable, it is assumed that be efghi.
C) simultaneously UI is shown structured message message, by traversing json object, is constructed the html page presentation of message, is given
Js event functions are arranged in each leaf attribute, and establish attribute alias and be really the mapping relations of attribute, configure people convenient for rule
Member's selection attribute of interest field and associated configuration relevant field data manipulation function.
D) it selects message field and configures output item, in UI display area, select attribute of interest and do required function configuration,
Such as selection attrName2 [0], data manipulation function is not configured.
E) selection message field and configuration condition item select attribute of interest and do required function configuration in UI display area,
Such as selection attrName31, configuration condition function attrName31！=" OFF ".
F) Response to selection behavior command, present case select the instruction of non-M2M type, and configuration backend application service adapter connects
Mouth dataStoreForIotDevice realizes that data are routed to storage service.
(3) execution of rule is completed.Rule executes logic, referring to shown in Fig. 6, in the present embodiment, is based on above-mentioned (two)
Rule configuration, output parameter is attrName2 [0], then the field in corresponding write-in rdTable table is efghi, conditional parameter
For attrName31, then the field in corresponding write-in rdTable table is abcde.
When this rule automotive engine system is partially received the message that topic is rulee/demod/devx in data receiver
Afterwards, depth structure message attributes msgJsonOfTopicName.attrName3.attrName31 will be searched from caching system
Even up after field, obtain value abcde, and write a value into rdTable and correspond to abcde field, it is right
The operation of msgJsonOfTopicName.attrName2 [0] is similar.So far, the insert operation of data is completed.
Then, the conditional information that rule is inquired from rule database, constructs regular SQL statement, in rdTable
Select operation is executed, is exported as a result, meeting the efghi field of rule；Finally, deleting the number to fail in rdTable
According to, usually presently written data, the release of safeguards system resource.
(4) the subsequent response instruction of rule definition is completed.Output result efghi in the present embodiment, after rule is executed
Field is called http interface dataStoreForIotDevice in a manner of POST, completes set number as main body of the packet content
According to routing.
