Structure.
The invention provides a kind of application layer protocol carrying Distributed Calculation semanteme.The present invention extends http protocol 1.1
And above version, increase new function；Both make use of existing protocol, it also avoid formulation standard software storehouse and api interface etc. more
Add large order.
Detailed description of the invention
For making the present invention become apparent, hereby it is described in detail below with preferred embodiment.
In http protocol 1.1 and above release protocol, existing method comprises GET, POST, PUT, DELETE etc., with the addition of
Self-defining extended method, starting with classifying from the Method of extension HTTP illustrates each step:
1, storage resource
Step 1: initiate the request of storage resource: defining protocol massages head, below table is request header parameter:
Step 2: server end return to client response, return the parameter such as following table of response:
The return code of normal flow such as following table
2, resource is obtained
Step 1, initiation obtain the request of specific resources: defining protocol massages head, below table is request header parameter:
Step 2: server end return to client response, return the parameter declaration of response:
The return code of normal flow such as following table
3, obtain resource lock, needed to obtain relevant lock in advance before Resource Calculation:
Step 1: initiate to obtain the request of resource lock: defining protocol massages head, below table is request header parameter:
Step 2: server end return to client response, return the parameter declaration of response:
The return code of normal flow such as following table:
4, release resource lock, completes to need afterwards, at Resource Calculation, the lock that release is relevant:
Step 1, the request of initiation release resource lock: definition protocol massages head, below table is request header parameter:
Step 2: server end return to client response, return the parameter declaration of response:
The return code of normal flow such as following table:
5, Resource Calculation, for collecting that given data resource can carry out being correlated with, average polymerization calculates:
Step 1: initiate the request of release resource lock: defining protocol massages head, below table is request header parameter:
Except heading also needs to define the formula of calculating in body body, incoming parameter name and value, the value of output,
All these contents use xml form to be described.Computing formula can but be not limited only to use JavaScript language describe.
Background server resolves incoming computation requests, carries out correlation computations and is then back to result set.
Step 2: server end return to client response, return the parameter declaration of response:
Comprise the architecture of calculating in the return body of response, also use Xml form.
The return code of normal flow such as following table
