为 TOML 文件和 golang 解析表中的键值对

Question

我有以下 TOML 文件结构：[database]host = "localhost"port = 8086https = trueusername = "root"password = "root"db = "test"[cloud]deviceType = "2be386e9bbae"deviceId = "119a705fa3b1"password = "test"token = "dqpx5vNLLTR34"endpoint = "mqtts://mqtt1.endpoint.com"[gps]#measurement = "gps"  [gps.msgpack]  topic = "/evt/gps/msgpack"  [gps.json]  topic = "/evt/gps/json"[imu]#measurement = "imu"  [imu.1]    tag = "NODE1"    topic = "/evt/imu1/msgpack"  [imu.2]    tag = "NODE2"    topic = "/evt/imu2/msgpack"我只想在表和表中设置一次measurement键，而不是在and和 for and中冗余设置gpsimumsgpackjson12使用注释掉的键以下代码有效

Answer 1

你说：

我想在 gps 表中设置测量键并且只可变一次而不是在 msgpack 和 json 以及 1 和 2 中冗余

你不这样做是因为 TOML 格式的创建者说：

因为我们需要一种体面的人类可读格式，它可以明确地映射到哈希表，而 YAML 规范长达 80 页，这让我很生气。不，JSON 不算数。你知道为什么。

如果您需要对一个键具有相同的值，例如，measurement您必须在每个子表中指定您想要的

您正确的 TOML 文件：

[database]

host = "localhost"

port = 8086

https = true

username = "root"

password = "root"

db = "test"

[cloud]

deviceType = "2be386e9bbae"

deviceId = "119a705fa3b1"

password = "test"

token = "dqpx5vNLLTR34"

endpoint = "mqtts://mqtt1.endpoint.com"

[gps]

[gps.msgpack]

topic = "/evt/gps/msgpack"

measurement = "gps"

[gps.json]

topic = "/evt/gps/json"

measurement = "gps"

[imu]

[imu.1]

measurement = "imu"

tag = "NODE1"

topic = "/evt/imu1/msgpack"

[imu.2]

measurement = "imu"

tag = "NODE2"

topic = "/evt/imu2/msgpack"
