How can you use cookies with superagent?
提问by Kuryaki
I'm doing cookie session management with express with something like this:
我正在使用 express 进行 cookie 会话管理，如下所示：
req.session.authentication = auth;
And I verify the authenticated urls with something like
我用类似的东西验证经过身份验证的网址
if(!req.session.authentication){res.send(401);}
Now I'm building tests for the URLs with mocha, superagentand should, however I can't seem to find a way to get/set the cookie with superagent. I even tried to request the login before the authenticated test but it is not working,
现在我正在使用 mocha、superagent和should为 URL 构建测试，但是我似乎无法找到使用 superagent 获取/设置 cookie 的方法。我什至试图在经过身份验证的测试之前请求登录，但它不起作用，
I have tried adding the request to the login in the before statement for the mocha BDD suite, however it is still telling me that the request is unauthorized, I have tested the authentication doing the requests from the browser, however it is not working from the suite any ideas why?
我已经尝试在 mocha BDD 套件的 before 语句中将请求添加到登录中，但是它仍然告诉我该请求未经授权，我已经测试了从浏览器发出请求的身份验证，但是它无法从套件任何想法为什么？

Use superagent.agent()(instead of plain old superagent) to make requests have persistent cookies. See 'Preserving cookies' in the superagent docs, or the code examples: agency.js, controller.test.js.
使用superagent.agent()（而不是普通的 old superagent）使请求具有持久性 cookie。请参阅superagent 文档中的“保留 cookie”，或代码示例：agency.js、controller.test.js。

Seems like following code works fine;
似乎以下代码工作正常；
req.set('Cookie', "cookieName1=cookieValue1;cookieName2=cookieValue2");
req.set('Cookie', "cookieName1=cookieValue1;cookieName2=cookieValue2");

If the issue is in sending cookies for CORS requests use .withCredentials()method
described here
如果问题在于为 CORS 请求发送 cookie，请使用此处描述的.withCredentials()方法
request
.get('http://localhost:4001/')
.withCredentials()
.end(function(err, res) { })

Since you mentioned you need to both get andset the cookie:
由于您提到您需要同时获取和设置 cookie：
Get:
得到：
const request = await Superagent.get('...')
const cookie = request.header['set-cookie']
Set:
放：
Superagent.post('...').set('Cookie', 'cookie_info')

A clean way to do it is:
一个干净的方法是：
- create a simple cookie store
- abstract set Cookie to send it in each request
- update the cookie only when needed
- 创建一个简单的 cookie 存储
- 抽象设置 Cookie 在每个请求中发送它
- 仅在需要时更新 cookie
Note I keep the same URL because I use graphql but you can make it a parameter:
注意我保留相同的 URL，因为我使用了 graphql，但您可以将其设置为参数：
const graph = agent =>
agent.post('/graph')
.set('cookie', cookieStore.get());
const handleCookie = res =>
cookieStore.set(res.headers['set-cookie'][0]);
let currentCookie="";
const cookieStore = {
set: cookie=>{currentCookie=cookie},
get: cookie=>currentCookie,
};
module.exports = {graph,connectTestUser,handleCookieResponse};
You can now just use graph(agent)to send a request and handleCookie(response)when you have a response that may update your cookie (set or clear), example:
当您有可能更新您的 cookie（设置或清除）的响应时，您现在可以使用graph(agent)发送请求和handleCookie(response)，例如：
graph(agent).end((err,res) => {
if (err) return done(err);
res.statusCode.should.equal(200);
handleCookie(res);
return done();
});
