使用NodeJS获取mpesa api中的授权令牌

Question

当使用nodejs从mpesa API获取access_token时，您可以运行如下代码

var request = require('request'),
    consumer_key = "YOUR_APP_CONSUMER_KEY",
    consumer_secret = "YOUR_APP_CONSUMER_SECRET",
    url = "https://sandbox.safaricom.co.ke/oauth/v1/generate?grant_type=client_credentials"
    auth = "Basic " + new Buffer(consumer_key + ":" + consumer_secret).toString("base64");

    request(
      {
        url : url,
        headers : {
          "Authorization" : auth
        }
      },
      function (error, response, body) {
        // TODO: Use the body object to extract OAuth access token
      }
    )

Node中弃用了用于生成Authorization过程中使用的auth值的Buffer方法。另一种选择是什么？

Answer 1

出于安全性和可用性方面的考虑，不建议使用

()和new Buffer()构造函数。请改用新的Buffer.alloc()、Buffer.allocUnsafe()或Buffer.from()构造方法。

我已经用同样的方法相当成功地接收到了访问令牌。以下是我的代码

​

const request = require('request');

exports.mpesaAuth = asyncHandler(async(req, res, next) => {
    const auth = new Buffer(
        `${process.env.MPESA_KEY}:${process.env.MPESA_SECRET}`
    ).toString('base64');
    request({
            url: process.env.MPESA_URL,
            headers: { 'Authorization': `Basic ${auth}` }

        },
        (err, response, body) => {
            if (err) {
                console.error(err);
            } else {
                res.status(200).json({
                    success: true,
                    body
                });
            }
        },
    );
});

我希望这能有所帮助。

以下是ES6中的代码：

  import axios from 'axios'
  const consumer_key = "YOUR_APP_CONSUMER_KEY";
  const consumer_secret = "YOUR_APP_CONSUMER_SECRET";
  const url = process.env.SAF_AUTH_URL;
  const Authorization = `Basic ${new Buffer.from(
    `${consumer_key}:${consumer_secret}`,
    'utf-8'
  ).toString('base64')}`;
  axios
    .get(url, {
      headers: {
        Authorization
      }
    })
    .then((response) => {
      // Handle Success
    })
    .catch((error) => {
       //Handle your error
    });
