所以我使用nodejs从我的服务器访问API（图例api联盟），我测试了使用httpie（一个简单的http客户端）访问api的路由，一切正常，没有任何问题
当我想使用Jest + supertest为我的api编写测试时，当我测试访问远程LOL api的路由时，总是会出现此错误
Response for preflight has invalid HTTP status code 401
当然，当我使用http客户端或webbrowser
时，我从未收到此错误测试方法
test('exist route should return 200 if summoner exist', done => {
request(app)
.get('/summoners/exist/yaskillin')
.expect('Content-Type', /json/)
.expect(200)
.then(res => {
expect(res.body.exist).toBeTruthy()
done()
})
})
路线方法
private exist(req: Request, res: Response, next: NextFunction) {
let name: string = req.params["name"];
return this.riotService
.getSummonerByName(name)
.then(result => {
console.log(result)
res.json({ exist: true });
})
.catch(err => {
console.log(err.config)
res.json({ exist: false });
});
}
错误

默认情况下，jest是jsdom模式下的跑步者，这意味着jest在浏览器中是跑步者，默认情况下是envirement，
需要做的是将其配置为在服务器中运行，如envirement 你需要把它放在你的jest.config文件中
