企业微信实现消息本地存档

最近了解到企业微信开始内测会话存档接口，可以实现将企业微信所有聊天记录拉取到本地服务器上，进行消息的备份存档。测试调用成功后，先记录下过程。

首先在“管理工具”下打开“会话内容存档”接口

选择试用开通，目前可以试用30天，试用期结束后需要付费使用。

开通后需要填写几个参数用于接口调用

可信IP地址：需要调用接口的服务器公网IP

消息加密公钥：自己生成RSA公钥和私钥，公钥用于加密，私钥用于解密

Secret：用于获取接口调用token

点击API文档可以查看调用步骤以及下载官方sdk

sdk中有demo源码可以测试

通过更改args[0]的值实现获取消息，输出媒体文件及获取媒体信息

成功获取到消息记录
