企业微信会话存档SDK（基于企业微信C版官方SDK封装），暂时只支持在linux环境下使用当前SDK。

1、安装 go module
go get -u github.com/NICEXAI/WeWorkFinanceSDK
2、从 github.com/NICEXAI/WeWorkFinanceSDK/lib 文件夹下复制 libWeWorkFinanceSdk_C.so 动态库文件到系统动态链接库默认文件夹下，或者复制到任意文件夹并在当前文件夹下执行 export LD_LIBRARY_PATH=$(pwd)命令设置动态链接库检索地址
3、把 module 引入到项目中即可使用
package main
import (
"bytes"
"fmt"
"github.com/NICEXAI/WeWorkFinanceSDK"
"io/ioutil"
"os"
"path"
)
func main() {
corpID := "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
corpSecret := "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
rsaPrivateKey := `
-----BEGIN RSA PRIVATE KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END RSA PRIVATE KEY-----
`
//初始化客户端
client, err := WeWorkFinanceSDK.NewClient(corpID, corpSecret, rsaPrivateKey)
if err != nil {
fmt.Printf("SDK 初始化失败：%v \n", err)
return
}
//同步消息
chatDataList, err := client.GetChatData(0, 100, "", "", 3)
if err != nil {
fmt.Printf("消息同步失败：%v \n", err)
return
}
for _, chatData := range chatDataList {
//消息解密
chatInfo, err := client.DecryptData(chatData.EncryptRandomKey, chatData.EncryptChatMsg)
if err != nil {
fmt.Printf("消息解密失败：%v \n", err)
return
}
if chatInfo.Type == "image" {
image := chatInfo.GetImageMessage()
sdkfileid := image.Image.SdkFileID
isFinish := false
buffer := bytes.Buffer{}
index_buf := ""
for !isFinish {
//获取媒体数据
mediaData, err := client.GetMediaData(index_buf, sdkfileid, "", "", 5)
if err != nil {
fmt.Printf("媒体数据拉取失败：%v \n", err)
return
}
buffer.Write(mediaData.Data)
if mediaData.IsFinish {
isFinish = mediaData.IsFinish
}
index_buf = mediaData.OutIndexBuf
}
filePath, _ := os.Getwd()
filePath = path.Join(filePath, "test.png")
err := ioutil.WriteFile(filePath, buffer.Bytes(), 0666)
if err != nil {
fmt.Printf("文件存储失败：%v \n", err)
return
}
break
}
}
}
