Introduction:
With the development of mobile Internet, mobile applications have become an indispensable part of people's lives. Field management is one of the necessary workflows for many companies and organizations. As a popular enterprise-level communication and collaboration tool, DingTalk provides powerful interfaces and functions that can help us quickly implement mobile applications for field management.

This article will introduce how to use DingTalk’s interface docking function to develop a fully functional field management application.

DINGTALK.ready(() => {
DINGTALK.runtime .permission.requestAuthCode(function (result) {

fetch('https://oapi.dingtalk.com/gettoken?appkey=' + DINGTALK_SK + '&appsecret=' + DINGTALK_SK + '&code=' + result.code)
  .then((response) => response.json())
  .then((responseJson) => {
    const accessToken = responseJson.access_token
    // 保存accessToken并跳转到下一页
  })

})
})
