curl 结果与 Python 请求结果之间存在差异

Question

我正在查询 New Relic API，并试图从它们提供的指标中提取 CPU 利用率。当我运行以下 curl 命令时（导出正确的代理设置后），我看到以下信息（其中包含我想要的百分比值）-

 curl -X GET "https://api.newrelic.com/v2/applications/140456413/hosts/21044947/metrics/data.json" -H "X-Api-Key:myapikey" -i -d 'names[]=CPU/User+Time&values[]=percent&summarize=true&from=2018-07-15 16:22:30&to=2018-07-16 16:22:30'

{"metric_data":{"from":"2018-07-15T16:22:30+00:00","to":"2018-07-16T16:22:30+00:00","metrics_not_found":[],"metrics_found":["CPU/User Time"],"metrics":[{"name":"CPU/User Time","timeslices":[{"from":"2018-07-15T16:22:00+00:00","to":"2018-07-16T16:22:00+00:00","values":{"percent":9.52}}]}]}}

但是，当我尝试在 Python 请求模块中实现它时，我感兴趣的 "Percent" 值返回 0。这是我调用它的代码 -

options = {"names[]": "CPU/User+Time", "values[]": "percent", "summarize": "true", "from": str(end_date), "to": str(start_date - datetime.timedelta(hours=6))}
path = "applications/140456413/hosts/" + server_id + "/metrics/data.json"
api_key = "myapikey"

headers = {'X-Api-Key': api_key}
url = "https://api.newrelic.com/v2/" + path
r = requests.get(url, headers=headers, data=options, proxies=myproxy.proxies)

这就是我得到的（注意百分比值现在为 0）-

{u'metric_data': {u'metrics': [{u'timeslices': [{u'values': {u'percent': 0}, u'to': u'2018-07-17T01:35:00+00:00', u'from': u'2018-07-16T07:35:00+00:00'}], u'name': u'CPU/User+Time'}], u'to': u'2018-07-17T01:35:59+00:00', u'metrics_found': [u'CPU/User+Time'], u'from': u'2018-07-16T07:35:59+00:00', u'metrics_not_found': []}}

如何调整 python 请求以匹配与 curl 命令相同的输出？我们最初使用 = 而不是 key/value 对在 "options" 变量内部传递选项，但是请求模块不会以这种格式处理它们。

这些是我引用的文档页面 -

谢谢。

Answer 1

稍微更改一下选项：

"values[]": "percent"

至：

"values": ["percent"]
