访问Postgresql结果

Question

我编写了一个查询，它返回如下结果集，

result = [
{"total_requests" : "4", "requesttimestamp" : null}, 
{"total_requests" : "2", "requesttimestamp" : null}, 
{"total_requests" : "4", "requesttimestamp" : null}, 
{"total_requests" : "7", "requesttimestamp" : null}, 
{"total_requests" : "1", "requesttimestamp" : 1.37412742E9}, 
{"total_requests" : "1", "requesttimestamp" : 1.37412781E9}, 
{"total_requests" : "1", "requesttimestamp" : 1.374127424E9}
]

当尝试以如下方式遍历它时

result[i]["total_requests"] ,result[i]["requesttimestamp"] 

为了得到结果对，它给出了未定义的结果对。

那么如何分别检索值对呢？

Answer 1

可以通过resulti.total_requests、resulti.requesttimestamp
