最近项目需要对接企业微信把马上要超过预警值消息推送给相关用户，这里网上看了下对接企业微信提供的官方文档以及相关文章这里做一下整理。

# 一、准备 #

为了便于测试，在开始对接前注册一个企业微信。

注册地址：[https://work.weixin.qq.com/wework\_admin/register\_wx?from=loginpage][https_work.weixin.qq.com_wework_admin_register_wx_from_loginpage]

①注册完毕后我们可以得到企业微信的企业ID

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3ExNTEwMjc4MDcwNQ_size_16_color_FFFFFF_t_70 1][]

这个企业微信很重要，待会我们接口请求要用到。

②创建企业应用

这里创建完毕后可以得到Agentld和Secret，我们后面对接也会用到

# 二、开始接口测试 #

获取access\_token

用access\_token拼接接口推送企业微信消息

测试200成功，完毕！
