javascript - 尝试使用 mocha 登录时出现错误 : expected 200 "OK", 得到 401 "Unauthorized"

Question

我正在尝试使用 passport passport-jwt 和 passport-local 为安全 API 提供用户身份验证，测试是给我带来一些问题。我目前正在尝试测试当我使用授权 header 集调用 /meals 时会返回餐食列表。

目前在 Mocha 中，当我尝试运行我的套件时，我收到错误:预期 200“OK”，得到 401“未经授权”，但我不明白为什么。

代码片段如下:

meals.test.js

// NPM imports
const request = require('supertest');
const expect = require('expect');
const {ObjectID} = require('mongodb');

// Local files
const app = require('./../app');
const {Meal} = require('./../models/meal');
const {meals, validUsers, populateUsers, populateMeals} = require('./seed/seed');

function createAuthenticatedRequest(loginDetails, done) {
    let authenticatedRequest = request.agent(app);
    authenticatedRequest
        .post('/login')
        .send(loginDetails)
        .end(function (error, response) {
            if (error) {
                throw error;
            }
            done(authenticatedRequest)
        });
}

beforeEach(populateMeals);
beforeEach(populateUsers);

经过两天的摸索和刺激，我找到了一个解决方案，发布在这里供其他人将来引用，创建了以下函数来创建授权 header 并将其返回以供请求使用。

// Auxiliary function.
function createLoginToken(server, loginDetails, done) {
    request(server)
        .post('/login')
        .send(loginDetails)
        .end(function(error, response) {
            if (error) {
                throw error;
            }
            let loginToken = response.body.token;
            done(loginToken);
        });
}

然后调用如下:

it('should get all the meals', (done) => {
    createLoginToken(app, { email: validUsers[0].email, password: 'secret'}, function(header) {
        request(app)
            .get('/meals')
            .set('Authorization', header)
            .expect(200)
            .expect((res) => {
                expect(res.body.length).toBe(2);
            })
            .end(done);
    });
});
