问题描述
我刚刚使用快速基本身份验证在nodejs中创建了基本身份验证
I just created the basic authentication in nodejs using express basic auth
var express = require('express');
var app = express();
// Authenticator
app.use(express.basicAuth('testuser','testpassword'));
app.get('/home', function(req, res) {
res.send('Hello World');
});
app.listen(process.env.PORT || 8080);
我收到以下错误.我不知道我哪里出了错.
I got the following error. I dont know where i went wrong.
app.use(express.basicAuth('testuser','testpassword'));
^
TypeError: Object function createApplication() {
var app = function(req, res, next) {
app.handle(req, res, next);
};
mixin(app, proto);
mixin(app, EventEmitter.prototype);
app.request = { __proto__: req, app: app };
app.response = { __proto__: res, app: app };
app.init();
return app;
} has no method 'basicAuth'

推荐答案
如注释中所述,Express 4不再与中间件一起提供,您可以直接从
As mentioned in the comments, Express 4 doesn't ship with middleware any longer, you can either copy the implementation directly from the express repo or use a solution similar to this:
var express = require('express');
var app = express();
// Authenticator
app.use(function(req, res, next) {
var auth;
// check whether an autorization header was send
if (req.headers.authorization) {
// only accepting basic auth, so:
// * cut the starting "Basic " from the header
// * decode the base64 encoded username:password
// * split the string at the colon
// -> should result in an array
auth = new Buffer(req.headers.authorization.substring(6), 'base64').toString().split(':');
// use Buffer.from in with node v5.10.0+
// auth = Buffer.from(req.headers.authorization.substring(6), 'base64').toString().split(':');
}
// checks if:
// * auth array exists
// * first value matches the expected user
// * second value the expected password
if (!auth || auth[0] !== 'testuser' || auth[1] !== 'testpassword') {
// any of the tests failed
// send an Basic Auth request (HTTP Code: 401 Unauthorized)
res.statusCode = 401;
// MyRealmName can be changed to anything, will be prompted to the user
res.setHeader('WWW-Authenticate', 'Basic realm="MyRealmName"');
// this will displayed in the browser when authorization is cancelled
res.end('Unauthorized');
} else {
// continue with processing, user was authenticated
next();
}
});
app.get('/home', function(req, res) {
res.send('Hello World');
});
app.listen(process.env.PORT || 8080);
