企業微信實現消息本地存檔

最近了解到企業微信開始內測會話存檔接口，可以實現將企業微信所有聊天記錄拉取到本地服務器上，進行消息的備份存檔。測試調用成功後，先記錄下過程。

首先在“管理工具”下打開“會話內容存檔”接口

選擇試用開通，目前可以試用30天，試用期結束後需要付費使用。

開通後需要填寫幾個參數用於接口調用

可信IP地址：需要調用接口的服務器公網IP

消息加密公鑰：自己生成RSA公鑰和私鑰，公鑰用於加密，私鑰用於解密

Secret：用於獲取接口調用token

點擊API文檔可以查看調用步驟以及下載官方sdk

sdk中有demo源碼可以測試

通過更改args[0]的值實現獲取消息，輸出媒體文件及獲取媒體信息

成功獲取到消息記錄
