''' 这个json格式，sourceMedia、subscribeJobInfo两层目录 sourceMedia下面其实又嵌套了字典和key-value值,但是加了中括号的就得加索引，这样才能获取到'''

列表与字典的获取，在列表与字典多层相互嵌套的情况下，获取某个属性的值，必须分清楚嵌套层次，然后才能获取值。还有列表一定要加中括号[0]，列表里面包含字典！不然不识别的！从0开始！ response_list={ "result": True, "errCode": None, "msg": None, "data": { "kafkaConsumedParams": [{ "partition": "0", "lastestOffset": "", "lastestOffsetTime": "", "snapNotConsumed": "", "incrNotConsumed": "", "snapExtracted": "0" }, { "partition": "1", "lastestOffset": "", "lastestOffsetTime": "", "snapNotConsumed": "", "incrNotConsumed": "", "snapExtracted": "0" }], "captureInitStatus": [{ "connectorName": "10.37.153.4-RDRS-rdrssit_4_1544012992078.6638", "startTime": None, "updateTime": None, "endTime": None, "status": "unstarted" }, { "connectorName": "10.37.153.5-RDRS-rdrssit_5_1544012992078.6638", "startTime": None, "updateTime": None, "endTime": None, "status": "unstarted" }] } } # print(type(response_list)) # 字典类型 # varcaptureInitStatus0 = response_list['data']['captureInitStatus'][0] # varcaptureInitStatus1 = response_list['data']['captureInitStatus'][1] # print(varcaptureInitStatus1) # 这样获取的依然是个字典， # print(type(varcaptureInitStatus1)) for i in (0,1): varcaptureInitStatus = response_list['data']['captureInitStatus'][i]['status'] # 字典里面有列表 print(varcaptureInitStatus)
