Python API调用的新手我在下面有JSON数据示例
我可以获取数据调用,例如(swell.*)
或(swell.minBreakingHeight)
,并且无需担心会返回所有swell数据。工作请求也好,
我似乎无法通过成功案例well.primary.height
缩小范围
显然,此处的格式不正确,并且不断返回[]
我如何获得额外的水平?
[{
timestamp: 1366902000,
localTimestamp: 1366902000,
issueTimestamp: 1366848000,
fadedRating: 0,
solidRating: 0,
swell: {
minBreakingHeight: 1,
absMinBreakingHeight: 1.06,
maxBreakingHeight: 2,
absMaxBreakingHeight: 1.66,
unit: "ft",
components: {
combined: {
height: 1.1,
period: 14,
direction: 93.25,
compassDirection: "W"
},
primary: {
height: 1,
period: 7,
direction: 83.37,
compassDirection: "W"
},
答案 0 :(得分:0)
使用您的数据代码:
data = [{
'timestamp': 1366902000,
'localTimestamp': 1366902000,
'issueTimestamp': 1366848000,
'fadedRating': 0,
'solidRating': 0,
'swell': {
'minBreakingHeight': 1,
'absMinBreakingHeight': 1.06,
'maxBreakingHeight': 2,
'absMaxBreakingHeight': 1.66,
'unit': "ft",
'components': {
'combined': {
'height': 1.1,
'period': 14,
'direction': 93.25,
'compassDirection': "W"
},
'primary': {
'height': 1,
'period': 7,
'direction': 83.37,
'compassDirection': "W"
}
}
}
}
]
In [54]: data[0]['timestamp']
Out[54]: 1366902000
In [55]: data[0]['swell']['components']['primary']['height']
Out[55]: 1
所以使用点符号,你应该打电话:
swell.components.primary.height
