如何从JSON响应中提取单个值？

使用

json.loads

使用以下命令访问字典值

['key']

resp_str = {  "name" : "ns1:timeSeriesResponseType",  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",  "value" : {    "queryInfo" : {      "creationTime" : 1349724919000,      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",      "criteria" : {        "locationParam" : "[ALL:103232434]",        "variableParam" : "[00060, 00065]"      },      "note" : [ {        "value" : "[ALL:103232434]",        "title" : "filter:sites"      }, {        "value" : "[mode=LATEST, modifiedSince=null]",        "title" : "filter:timeRange"      }, {        "value" : "sdas01",        "title" : "server"      } ]    }  },  "nil" : false,  "globalScope" : true,  "typeSubstituted" : false}

会翻译成python字典

resp_dict = json.loads(resp_str)resp_dict['name'] # "ns1:timeSeriesResponseType"resp_dict['value']['queryInfo']['creationTime'] # 1349724919000
