Question

与Splunk相比，这更像是一个python问题，但是如果有人这样做的话会有所帮助...特别是here，这里讨论了在单个POST中将多个指标发送到服务器。他们提供的示例是使用curl并将整个有效负载包装在单引号（'）中，例如

curl -k http://<IP address or host name or load balancer name>:8088/services/collector  \
-H "Authorization: Splunk 98a1e071-bc35-410b-8642-78ce7d829083"                         
\
-d '{"time": 1505501013.000,"source":"disk","host":"host_99","fields": 
{"region":"us-west-1","datacenter":"us-west- 1a","rack":"63","os":"Ubuntu16.10","arch":"x64","team":"LON","service":"6","service_version":"0","service_environment":"test","path":"/dev/sda1","fstype":"ext3","_value":999311222774,"metric_name":"total"}}
{"time": 1505511013.000,"source":"disk","host":"host_99","fields": 
{"region":"us-west-1","datacenter":"us-west-1a","rack":"63","os":"Ubuntu16.10","arch":"x64","team":"LON","service":"6","service_version":"0","service_environment":"test","path":"/dev/sda1","fstype":"ext3","_value":1099511627776,"metric_name":"total"}}'

我的问题是如何在python中做同样的事情-也就是说，您不能像curl命令中那样将多个JSON对象用单引号引起来-这只会使整个有效负载成为字符串。还有其他包装可以用于此目的吗？

所以，这可行：

payload = {"time": 1505501013.000,"source":"disk","host":"host_99","fields": 
{"region":"us-west-1","datacenter":"us-west- 1a","rack":"63","os":"Ubuntu16.10","arch":"x64","team":"LON","service":"6","service_version":"0","service_environment":"test","path":"/dev/sda1","fstype":"ext3","_value":999311222774,"metric_name":"total"}}

但这不是：

payload = {"time": 1505501013.000,"source":"disk","host":"host_99","fields": 
{"region":"us-west-1","datacenter":"us-west- 1a","rack":"63","os":"Ubuntu16.10","arch":"x64","team":"LON","service":"6","service_version":"0","service_environment":"test","path":"/dev/sda1","fstype":"ext3","_value":999311222774,"metric_name":"total"}}
 {"time": 1505511013.000,"source":"disk","host":"host_99","fields": 
{"region":"us-west-1","datacenter":"us-west-1a","rack":"63","os":"Ubuntu16.10","arch":"x64","team":"LON","service":"6","service_version":"0","service_environment":"test","path":"/dev/sda1","fstype":"ext3","_value":1099511627776,"metric_name":"total"}}

仅供参考，然后POST如下：

 resp = requests.post(splunkurl,json=payload,headers=headers)

好吧，“多个json对象”在它是对象的列表之前不是有效的json。

通常，python不在乎（就像其他任何网络工具一样），json只是数据格式，您需要使用其他格式。因此，您需要自己构造文本有效载荷，即OrderBy()，然后通过网络客户端将其作为“原始”数据发送。

我非常怀疑主流http库是否提供了这样的用例。

不确定拒绝的原因，即requests库（对于高级网络来说是一种标准的事实）具有有效处理有效载荷的功能：

json.dumps(payload1) + json.dumps(payload2)

Json与http本身无关，它只是序列化数据的一种方法。大多数客户最终都将使用requests.post(url, data={'v1': 1, 'v2': 2}) # will encode it as form data requests.post(url, json={'v1': 1, 'v2': 2}) # will encode as json requests.post(url, data="{'v1': 1}{'v2': 2}") # will send as-is，这根本不在乎，唯一的问题是库是否提供了一种简单的方式来发送原始数据

Python等价于将POST有效负载包装在单引号中
