JSON RPC 2.0: response that is part error and part result

Question

What is the standard approach to returning a JSON RPC response when there is only partial failure? It appears that both 'result' and 'error' cannot both be set.

We have a case where a server is aggregating results across several sites running the same API. The reason for the aggregation is due to the Same-Origin Policy. Each site may respond with either a result or an error. If some respond with a result and others with an error, then what does the aggregation server return as the complete response to the original caller?

a =(method)=> b
              b =(method)=> c
              b =(method)=> d
              b <=(error)== c
              b <=(result)= d
a <=(??????)= b

Is it best to simply return two responses (one with any errors and no 'id' and one with the results and an 'id' suggesting this is the last response)?

服务器职责是聚合并返回可能包含错误的结果。这是您的客户所期望的。

--> {"jsonrpc": "2.0", "method": "getResults", "id": 1}

<-- {"jsonrpc": "2.0", "result": [ "success", "error" ], "id": 1}

如果服务器本身因任何意外原因无法处理请求，您应该返回错误。
