为什么我无法使用 devise_token_auth 和 curl 退出？

Question

我正在使用带有 devise_token_auth 的 rails-api 进行身份验证。我可以通过以下方式毫无问题地登录：

curl -i http://localhost:3000/api/v1/auth/sign_in -F email="user@nowhere.org" -F password="password"

但是，退出失败并显示 404 和错误“用户未找到或未登录”。通过：

curl -X DELETE -i http://localhost:3000/api/v1/auth/sign_out

我已经尝试过使用多种参数和标头值组合的命令变体，例如：

curl -X DELETE -i http://localhost:3000/api/v1/auth/sign_out -F email="user@nowhere.org" -H Access-Token="Ae1yaTYLkSAgdhz3LtPAZg" -H Client="9AmYF6NS8tP6EOD5nPSuxw" -H Expiry="1443073493" -H Uid="user@nowhere.org" -H Token-Type="Bearer"

无济于事。类似构造的 RSpec 测试也失败并出现相同的响应和错误，并且日志表明请求是通过 DeviseTokenAuth::SessionsController#destroy 作为 JSON 处理的。

当然，我实际上并没有使用 curl 进行身份验证；只是在编写相关代码之前验证请求结构。

Answer 1

回答我自己的问题，我没有通过 sign_out 请求正确返回某些 sign_in 响应标头值。

I found a related post 指出了一些关键的标头。诀窍是从 sign_in 响应中捕获访问令牌、客户端和 uid 标头值，然后将它们作为参数包含在 sign_out 请求中：

curl -i -X DELETE http://localhost:3000/api/v1/auth/sign_out -F access-token="Ae1yaTYLkSAgdhz3LtPAZg" -F client="9AmYF6NS8tP6EOD5nPSuxw" -F uid="user@nowhere.org"

这里有一个 RSpec 测试来说明和验证：

require 'rails_helper'

RSpec.describe "Authentication", type: :request do

  it "logs a user out" do
    user = User.create!(
      name: "Some Dude", 
      email: "user@nowhere.org",
      password: "password", 
      confirmed_at: Date.today
    )

    # initial sign in to generate a token and response
    post api_v1_user_session_path, {
      email: user.email, 
      password: user.password
    }

    expect(user.reload.tokens.count).to eq 1

    # sign out request using header values from sign in response
    delete destroy_api_v1_user_session_path, {
      "access-token": response.header["access-token"], 
      client: response.header["client"], 
      uid: response.header["uid"]
    }

    response_body = JSON.load(response.body)
    expect(response_body["errors"]).to be_blank
    expect(response.status).to eq 200
    # user token should be deleted following sign out
    expect(user.reload.tokens.count).to eq 0
  end

end

Answer 2

具体来说，请执行以下步骤：

第 1 步：

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST http://localhost:3000/api/v1/auth/sign_in -d "{\"email\":\"user@example.com\",\"password\":\"password\"}"

你会得到这样的回应：

* Connected to localhost (::1) port 3000 (#0)

> Host: localhost:3000

{"data":{"id":6,"provider":"email","uid":"user@example.com","name":"testuser","nickname":null,"image":null,"email":"user@example.com"}}%

第 2 步：

现在，您要注销用户。

curl -i -X DELETE http://localhost:3000/api/v1/auth/sign_out -F access-token="BqXcWQi0-9faLyxP1LnUKw" -F client="dYSqVgM9VT6fV9Y5MFWpJQ" -F uid="user@example.com"

你会得到这样的回应：

HTTP/1.1 200 OK
X-Frame-Options: SAMEORIGIN
X-Xss-Protection: 1; mode=block
X-Content-Type-Options: nosniff
Content-Type: application/json; charset=utf-8
Etag: W/"7363e85fe9edee6f053a4b319588c086"
Cache-Control: max-age=0, private, must-revalidate

Connection: Keep-Alive

{"success":true}%

在第 2 步中，我根据我们在第 1 步中收到的响应添加了 access-token 和 client（Access-Token: BqXcWQi0 -9faLyxP1LnUKw 和客户：dYSqVgM9VT6fV9Y5MFWpJQ）。

就是这样！ :)
