无效的有效负载-Slack API JSON [英] Invalid payload - Slack api JSON

问题描述

我正在使用groovy脚本通过松弛api发送POST，目前我正在返回 invalid_payload ，我认为这很可能是由于JSON格式所致，我知道松弛的api期望它带有双引号的JSON，但我似乎无法将变量传递到JSON对象中

I am using a groovy script to send a POST using the slack api, at present i am getting invalid_payload returned and i think this is most likely due to the formatting of my JSON, i know the slack api expects it JSON with double quotes but i cant seem to be able to pass a variable into the JSON object

SUCCESS_MESSAGE = '{"attachments": [{"color": "#2A9B3A", "author_name": ${DEV_NAME}, "title": "Build Status", "title_link": ${BUILD_URL}, "text": "Successful Build" }]}'
def response = ["curl", "-X", "POST", "-H", "Content-Type: application/json", "-d", "${SUCCESS_MESSAGE}", "https://hooks.slack.com/services/${SLACK_WEBHOOK}"].execute().text

有人知道我将如何正确格式化我的 SUCCESS_MESSAGE 变量，这样我就不会收到错误消息?

Does anyone know how I would correctly format my SUCCESS_MESSAGE var so i dont get the error ?

谢谢

推荐答案

1. 您需要引用 DEV_NAME 和 BUILD_URL 变量扩展名，以便JSON字符串有效.
2. 您的整个字符串需要用"而不是'括起来，以便实际上扩展变量

3. 您需要在字符串中 escape " ，以便它们出现在JSON字符串中.

1. You need to quote your DEV_NAME and BUILD_URL variable expansions so the JSON string is valid.
2. Your whole string needs to be enclosed in " instead of ' so the variables are actually expanded

3. And you need to escape the " inside your string so they appear in your JSON string.

SUCCESS_MESSAGE ="{\"附件\:[{\"颜色\:\"#2A9B3A \，\"作者名\:\" $ {DEV_NAME} \，\"标题\:\"Build Status \"，\"title_link \":\"$ {BUILD_URL} \"，\"text \":\"Successful Build \"}]}"`

SUCCESS_MESSAGE = "{\"attachments\": [{\"color\": \"#2A9B3A\", \"author_name\": \"${DEV_NAME}\", \"title\": \"Build Status\", \"title_link\": \"${BUILD_URL}\", \"text\": \"Successful Build\" }]}"`

或者，您可以通过更好的编程方式来生成JSON.如果您的通知变得更加复杂，这将很有帮助:

Alternatively you can generate the JSON in much nicer programmatic way. Which would be helpful if your notifications got a bit more complicated:

def notification = [
  attachments: [
    [
      color: "#2A9B3A",
      author_name: DEV_NAME,
      title: "Build Status",
      title_link: BUILD_URL,
      text: "Successful Build"
    ]
  ]
]

def response = ["curl", "-X", "POST", "-H", "Content-Type: application/json", "-d", JsonOutput.toJson(notification), "https://hooks.slack.com/services/${SLACK_WEBHOOK}"].execute().text
