飞书开放平台-发送文本&富文本消息

前言

本文我们基于飞书开放平台提供了服务端SDK，来教下大家如何发送文本&富文本消息

代码示例

本文我们基于飞书开平提供的go-sdk进行展示，go-sdk的github地址为：
https://github.com/larksuite/oapi-sdk-go

代码示例如下：

package main

import (
    "context"
    "fmt"
    lark "github.com/larksuite/oapi-sdk-go/v3"
    larkcore "github.com/larksuite/oapi-sdk-go/v3/core"
    larkim "github.com/larksuite/oapi-sdk-go/v3/service/im/v1"
    "os"
)

func sendTextMsg(client *lark.Client) {

    // Build the text message content
    //content := "{\"text\":\"hello,world\\n加多\"}"
    content := larkim.NewTextMsgBuilder().
        Text("hello,world").
        AtUser("ou_c245b0a7dff2725cfa2fb104f8b48b9d", "加多").
        Build()

    resp, err := client.Im.Message.Create(context.Background(), larkim.NewCreateMessageReqBuilder().
        ReceiveIdType(larkim.ReceiveIdTypeOpenId).
        Body(larkim.NewCreateMessageReqBodyBuilder().
            MsgType(larkim.MsgTypeText).
            ReceiveId("ou_c245b0a7dff2725cfa2fb104f8b48b9d").
            Content(content).
            Build()).
        Build())

    if err != nil {
        fmt.Println(err)
        return
    }

    if !resp.Success() {
        fmt.Println(resp.Code, resp.Msg, resp.RequestId())
        return
    }

    fmt.Println(resp.Data.MessageId)
    fmt.Println(larkcore.Prettify(resp))
    fmt.Println(resp.RequestId())
}
func sendPostMsgUseBuilder(client *lark.Client) {
    // 第一行
    // 文本 &超链接
    zhCnPostText := &larkim.MessagePostText{Text: "第一行:", UnEscape: false}
    enUsPostText := &larkim.MessagePostText{Text: "英文内容", UnEscape: false}

    zhCnPostA := &larkim.MessagePostA{Text: "超链接", Href: "http://www.baidu.com", UnEscape: false}
    enUsPostA := &larkim.MessagePostA{Text: "link", Href: "http://www.baidu.com", UnEscape: false}

    // At人
    zhCnPostAt := &larkim.MessagePostAt{UserId: "ou_c245b0a7dff2725cfa2fb104f8b48b9d", UserName: "加多"}
    enCnPostAt := &larkim.MessagePostAt{UserId: "ou_c245b0a7dff2725cfa2fb104f8b48b9d", UserName: "jiaduo"}

    // 图片
    zhCnPostImage := &larkim.MessagePostImage{ImageKey: "img_v2_a66c4f79-c7b5-4899-b5e3-622766c4f82g"}
    enCnPostImage := &larkim.MessagePostImage{ImageKey: "img_v2_a66c4f79-c7b5-4899-b5e3-622766c4f82g"}

    // 第二行
    // 文本 &超链接
    zhCnPostText21 := &larkim.MessagePostText{Text: "第二行:", UnEscape: false}
    enUsPostText21 := &larkim.MessagePostText{Text: "英文内容", UnEscape: false}

    // 图片
    zhCnPostImage2 := &larkim.MessagePostImage{ImageKey: "img_v2_a66c4f79-c7b5-4899-b5e3-622766c4f82g"}
    enCnPostImage2 := &larkim.MessagePostImage{ImageKey: "img_v2_a66c4f79-c7b5-4899-b5e3-622766c4f82g"}

    // 中文
    zhCn := larkim.NewMessagePostContent().
        ContentTitle("我是一个标题").
        AppendContent([]larkim.MessagePostElement{zhCnPostText, zhCnPostA, zhCnPostAt}).
        AppendContent([]larkim.MessagePostElement{zhCnPostImage}).
        AppendContent([]larkim.MessagePostElement{zhCnPostText21}).
        AppendContent([]larkim.MessagePostElement{zhCnPostImage2}).
        Build()

    // 英文
    enUs := larkim.NewMessagePostContent().
        ContentTitle("im a title").
        AppendContent([]larkim.MessagePostElement{enUsPostA, enUsPostText, enCnPostAt}).
        AppendContent([]larkim.MessagePostElement{enCnPostImage}).
        AppendContent([]larkim.MessagePostElement{enUsPostText21}).
        AppendContent([]larkim.MessagePostElement{enCnPostImage2}).
        Build()

    // 构建消息体
    postText, err := larkim.NewMessagePost().ZhCn(zhCn).EnUs(enUs).Build()
    if err != nil {
        fmt.Println(err)
        return
    }

    resp, err := client.Im.Message.Create(context.Background(), larkim.NewCreateMessageReqBuilder().
        ReceiveIdType(larkim.ReceiveIdTypeOpenId).
        Body(larkim.NewCreateMessageReqBodyBuilder().
            MsgType(larkim.MsgTypePost).
            ReceiveId("ou_c245b0a7dff2725cfa2fb104f8b48b9d").
            Content(postText).
            Build()).
        Build())

    if err != nil {
        fmt.Println(err)
        return
    }

    if resp.Success() {
        fmt.Println(larkcore.Prettify(resp))
        fmt.Println(*resp.Data.MessageId)
    } else {
        fmt.Println(resp.RequestId(), resp.Msg, resp.Code)
    }

}

func main() {
    // 创建 api client
    var appID, appSecret = os.Getenv("APP_ID"), os.Getenv("APP_SECRET")
    client := lark.NewClient(appID, appSecret)

    // 发送文本消息
    sendTextMsg(client)

    // 发送富文本消息
    sendPostMsgUseBuilder(client)
}

运行后，机器人就会给指定的接受者发送两个消息，消息内容如下：
