问题描述

将脚本移至其他服务器时发生错误.

Getting error when script move to other server.

当前版本:

Ubuntu 16.04.4 LTS  
Node - v10.9.0  
NPM - 6.2.0  

以前的版本:

Ubuntu 14.04.3 LTS
NPM - 3.10.10
Node - v6.10.3


exports.basicAuthentication = function (req, res, next) {
    console.log("basicAuthentication");
    if (!req.headers.authorization) {
        return res.status(401).send({
            message: "Unauthorised access"
        });
    }
    var auth = req.headers.authorization;
    var baseAuth = auth.replace("Basic", "");
    baseAuth = baseAuth.trim();
    var userPasswordString = new Buffer(baseAuth, 'base64').toString('ascii');
    var credentials = userPasswordString.split(':');

    var username = credentials[0] !== undefined ? credentials[0] : '';
    var password = credentials[1] !== undefined ? credentials[1] : '';
    var userQuery = {mobilenumber: username, otp: password};
    console.log(userQuery);
    User.findOne(userQuery).exec(function (err, userinfo) {
        if (err || !userinfo) {
             return res.status(401).send({
                message: "Unauthorised access"
             });
        } else {
            req.user = userinfo;
            next();
        }
    });

 }

推荐答案

new Buffer(number)            // Old
Buffer.alloc(number)          // New


new Buffer(string)            // Old
Buffer.from(string)           // New


new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New


new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New


注意,在当前的Node.js版本上,Buffer.alloc()也比新的Buffer(size).fill(0)更快,否则您需要这样做确保填零.


Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.
