使用CURL在InfluxDB中插入行 [英] Insert line in InfluxDB using CURL

问题描述

我有以下通过C＃完成的POST请求：

I have the following POST request which is done from C#:

POST http://192.168.123.27:8086/write?db=HWDB HTTP/1.1
Content-Type: text/plain; charset=utf-8
Host: 192.168.123.27:8086
Content-Length: 97
Expect: 100-continue
Connection: Keep-Alive

HARDWARE,CPU=1 count=91i 1456298998307783936
HARDWARE,CPU=2 count=92i 1456298998307783936

<我想使用CURL进行相同的请求。我正在使用以下命令：

I want to do the same request using CURL. I'm using the following command:

curl -i -XPOST http://192.168.123.27:8086/write?db=HWDB --data-binary "HARDWARE,CPU="1" value=91, CPU="2" value=92 1422568543702900257"

这将返回错误：

{"error":"unable to parse 'HARDWARE,CPU=1 value=91i, CPU=2 value=92i 1422568543702900257': invalid field format"}

我应该如何更改CURL命令的工作方式？我正在Windows上运行CURL，如果我使用的话：

How should I change the CURL command to work? I'm running CURL from Windows, if I use:

curl -i -XPOST http://192.168.123.27:8086/write?db=HWDB --data-binary "HARDWARE,CPU=1 value=91"

数据已正确插入DB中。还尝试使用InfluxDB文档中的示例从文件插入：

data is correctly inserted in DB. Also tried to insert from file using the example from InfluxDB documentation:

curl -i -XPOST http://192.168.123.27:8086/write?db=HDWB --data-binary @data.txt

这将返回：

{"error":"partial write:\nunable to parse 'cpu_load_short,host=server02 value=0.
67\r': invalid number\nunable to parse    'cpu_load_short,host=server02,region=us-w
est value=0.55 1422568543702900257\r': bad timestamp"}

data.txt的内容：

Content of data.txt:

cpu_load_short,host=server02 value=0.67
cpu_load_short,host=server02,region=us-west value=0.55 1422568543702900257
cpu_load_short,direction=in,host=server01,region=us-west value=2.0 1422568543702900257

推荐答案

关于 data.txt 文件，Windows是此处的关键因素。几乎可以肯定的是，在行尾引入了CRLF，而不仅仅是换行。请参阅

Regarding the data.txt file, Windows is the key factor here. It is almost certainly introducing a CRLF rather than just a linefeed at the end of the lines. See the InfluxDB docs for more.

至于帖子顶部的直接示例：

As for the direct example at the top of your post:

curl -i -XPOST http://192.168.123.27:8086/write?db=HWDB --data-binary "HARDWARE,CPU="1" value=91, CPU="2" value=92 1422568543702900257"

内容不是有效的线路协议格式，并且永远无法正常工作。每个点都必须换行，并且值不能在点之间共享。剥离 curl 语法，这是尝试的写法：

the content is not valid line protocol format and can never work. Each point must be on a new line, and values cannot be shared between points. Stripping out the curl syntax, this is the attempted write:

HARDWARE,CPU="1" value=91, CPU="2" value=92 1422568543702900257

实际的有效语法是：

HARDWARE,CPU="1" value=91 1422568543702900257
HARDWARE,CPU="2" value=92 1422568543702900257
