我试图让这个bash脚本运行speedtest
(speedtest-cli),然后通过curl将输出作为变量传递给pushbullet。
#!/bin/bash
speed=$(speedtest --simple)
curl --header 'Access-Token: <-ACCESS-TOKEN->' \
--header 'Content-Type: application/json' \
--data-binary {"body":"'"$speed"'","title":"SpeedTest","type":"note"}' \
--request POST \
https://api.pushbullet.com/v2/pushes
其他命令在使用此方法时运行良好(例如whoami
),但speedtest
和ifconfig
只会出现如下错误:
{"error":{"code":"invalid_request","type":"invalid_request","message":"Failed to decode JSON body.","cat":"(=^‥^=)"},"error_code":"invalid_request"}
答案 0 :(得分:0)
你的报错是错误的:
speed=$(speedtest --simple)
curl --header 'Access-Token: o.4q87SC5INy6nMQZqVHJeymwRsvMXW74j' \
--header 'Content-Type: application/json' \
--data-binary "{\"body\":\"$speed\",\"title\":\"SpeedTest\",\"type\":\"note\"}" \
--request POST \
https://api.pushbullet.com/v2/pushes
从这里阅读文档简化了引用:
speed=$(speedtest --simple)
curl --header 'Access-Token: o.4q87SC5INy6nMQZqVHJeymwRsvMXW74j' \
--header 'Content-Type: application/json' \
--data-binary @- \
--request POST \
https://api.pushbullet.com/v2/pushes <<EOF
{ "body": "$speed",
"title": "SpeedTest",
"type": "note"
}
EOF
但是,一般情况下,您不应该假设变量的内容是正确编码的JSON字符串,因此请使用jq
之类的工具为您生成JSON。
jq -n --arg data "$(speedtest --simple)" \
'{body: $data, title: "SpeedTest", type: "note"}' |
curl --header 'Access-Token: o.4q87SC5INy6nMQZqVHJeymwRsvMXW74j' \
--header 'Content-Type: application/json' \
--data-binary @- \
--request POST \
https://api.pushbullet.com/v2/pushes
这很容易重构:
post_data () {
url=$1
token=$2
data=$3
jq -n --arg d "$data" \
'{body: $d, title: "SpeedTest", type: "note"}' |
curl --header "Access-Token: $token" \
--header 'Content-Type: application/json' \
--data-binary @- \
--request POST \
"$url"
}
post_data "https://api.pushbullet.com/v2/pushes" \
"o.4q87SC5INy6nMQZqVHJeymwRsvMXW74j" \
"$(speedtest ---simple)"
