我是 golang 的新手，我正在編寫一個腳本來使用傳入的 webhook 向 slack 發送消息。slackBody, _ := json.Marshal(SlackRequestBody{Text: msg, EventName: "xxx", AccountId: "xxx", EventTime: "xxxxx", UserName: "xxxx", yyy: "xx", Status: "xx"}) fmt.Println(string(slackBody)) //test := ioutil.ReadAll(bytes.NewBuffer(slackBody)) req, err := http.NewRequest(http.MethodPost, webhookUrl, bytes.NewBuffer(slackBody)) if err != nil { return err } req.Header.Add("Content-Type", "application/json") client := &http.Client{Timeout: 10 * time.Second} resp, err := client.Do(req)這個帖子請求只包含“req”請求的幾個字。你能幫我弄清楚這個問題嗎？

這里沒有錯bytes.NewBuffer() 。從 slack 的角度來看，它只識別“文本”字段提供的消息。你需要重新設計你的SlackRequestBody結構。當您使用 Webhook API 發送消息時，您的請求正文應遵循slack.
POST https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
Content-type: application/json
{
"text": ...
"blocks": ...
"attachments": ...
"thread_ts": ...
"mrkdwn": ...
... ... ...
}
所以，你的SlackRequestBody結構應該是這樣的：
package main
import (
"encoding/json"
"fmt"
"time"
)
type SlackRequestBody struct {
Text string `json:"text"`
Blocks []Block `json:"blocks,omitempty"`
ThreadTimestamp string `json:"thread_ts,omitempty"`
Mrkdwn bool `json:"mrkdwn,omitempty"`
}
type Block struct {
BlockID string `json:"block_id,omitempty"`
Type string `json:"type"`
Text Text `json:"text"`
}
type Text struct {
Type string `json:"type"`
Text string `json:"text"`
}
func main() {
var payload = &SlackRequestBody{
Text: "Your message",
Blocks: []Block{
{
Type: "section",
Text: Text{
Type: "plain_text",
Text: "User Name: XXXX",
},
BlockID: "username",
},
{
Type: "section",
Text: Text{
Type: "plain_text",
Text: "Event Time: " + time.Now().String(),
},
BlockID: "eventTime",
},
},
}
data, err := json.Marshal(payload)
if err != nil {
panic(err)
}
fmt.Println(string(data))
}
去游樂場
輸出：
{
"text":"Your message",
"blocks":[
{
"block_id":"username",
"type":"section",
"text":{
"type":"plain_text",
"text":"User Name: XXXX"
}
},
{
"block_id":"eventTime",
"type":"section",
"text":{
"type":"plain_text",
"text":"Event Time: 2020-03-29 14:11:33.533827881 +0600 +06 m=+0.000078203"
}
}
]
}
我會推薦你使用 slack 的官方go 客戶端。它將提供更大的靈活性?？鞓肪幋a。
