第一步:注册钉钉企业账号

打开链接：https://oa.dingtalk.com/#/login，注册账号即可

第二步：创建应用

以创建e应用为例：

还需要授权一个开发人员，并获取CorpSecret，需要把corpId和CorpSecret作为参数请求api接口获取AccessToken，后面的所有接口都需要AccessToken

第三步：接入接口

一、获取token

 1 const corpid = 'dingd***587da6ee21d35c2f4657eb63***';

 2 const corpsecret = '*********';

 3 const requestPromise = require("request-promise");

 4

 5 const getAccessToken = async (corpid, corpsecret) => {

 6   // https://oapi.dingtalk.com/gettoken?corpid={corpid}&corpsecret={corpSecret或开发授权码}

 7   const result = await requestPromise({ uri: 'https://oapi.dingtalk.com/gettoken', qs: { corpid, corpsecret } });

 8   console.log(result);

 9 };

10 getAccessToken(corpid, corpsecret);

二、promise请求接口封装

function request(url, method, params, headers = {}) {
const options = {
url,
method,
// timeout: 3000,
headers: Object.assign(headers, {
'content-type': 'application/json',
}),
rejectUnauthorized: false, // https
json: true,
};
switch (method) {
case 'POST':
case 'PUT':
options.body = params;
break;
case 'GET':
case 'DELETE':
options.qs = params;
break;
default:
break;
}
return new Promise((resolve, reject) => {
request(options, (error, response, body) => {
if (!error) {
resolve(body);
} else {
reject(error);
}
});
});
.catch (error => ({
msg: error.message,
}));
}

三、接口见代码（后端使用koa.js）

const host = 'https://oapi.dingtalk.com/';

以上针对的是钉钉企业内部应用

如果是ISV开发者应用，则需要通过接口获取企业的基本信息

nodejs签名实现

/*
* 把timestamp + "\n" + suiteTicket当做签名字符串， suiteSecret做为签名秘钥，
* 使用HmacSHA256算法计算签名，然后进行Base64 encode获取最后结果。
* 然后把签名参数再进行urlconde，加到请求url后面。
*/
const crypto = require('crypto');
const accessKey = 'suiteqh0ljtdheuee****'; // suiteKey
const suiteSecret = '******';
const suiteTicket = 'TestSuiteTicket';
const timestamp = Date.now();
const stringToSign = timestamp + "\n" + suiteTicket;
const hash = crypto.createHmac('sha256', suiteSecret)
.update(stringToSign, 'utf8')
.digest().toString('base64');
console.log(hash);
var request = require("request");
var urlencode = require('urlencode');
var options = {
method: 'POST',
url: 'https://oapi.dingtalk.com/service/get_auth_info',
qs: {
signature: hash,
timestamp: timestamp,
suiteTicket: suiteTicket,
accessKey: accessKey
},
headers: {
'Cache-Control': 'no-cache',
'Content-Type': 'application/json'
},

json: true
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
