無密碼驗證可以讓你只輸入一個 email 而無需輸入密碼即可登入系統。這是一種比傳統的電子郵件/密碼驗證方式登入更安全的方法。

下麵我將為你展示，如何在 Go[1] 中實現一個 HTTP API 去提供這種服務。

流程

◈ 使用者輸入他的電子郵件地址。
◈ 伺服器建立一個臨時的一次性使用的程式碼（就像一個臨時密碼一樣）關聯到使用者，然後給使用者郵箱中傳送一個“魔法連結”。
◈ 使用者點選魔法連結。
◈ 伺服器提取魔法連結中的程式碼，獲取關聯的使用者，並且使用一個新的 JWT 重定向到客戶端。
◈ 在每次有新請求時，客戶端使用 JWT 去驗證使用者。

必需條件

◈ 資料庫：我們為這個服務使用了一個叫 CockroachDB[2] 的 SQL 資料庫。它非常像 postgres，但它是用 Go 寫的。
◈ SMTP 伺服器：我們將使用一個第三方的郵件伺服器去傳送郵件。開發的時我們使用 mailtrap[3]。Mailtrap 傳送所有的郵件到它的收件箱，因此，你在測試時不需要建立多個假郵件帳戶。

從 Go 的主頁[4] 上安裝它，然後使用 go version（1.10.1 atm）命令去檢查它能否正常工作。

從 CockroachDB 的主頁[5] 上下載它，展開它並新增到你的 PATH 變數中。使用 cockroach version（2.0 atm）命令檢查它能否正常工作。

資料庫樣式

現在，我們在 GOPATH 目錄下為這個專案建立一個目錄，然後使用 cockroach start 啟動一個新的 CockroachDB 節點：

  1. cockroach start --insecure --host 127.0.0.1

它會輸出一些內容，找到 SQL 地址行，它將顯示像 postgresql://root@127.0.0.1:26257?sslmode=disable 這樣的內容。稍後我們將使用它去連線到資料庫。

使用如下的內容去建立一個 schema.sql 檔案。

  1. DROP DATABASE IF EXISTS passwordless_demo CASCADE;
  2. CREATE DATABASE IF NOT EXISTS passwordless_demo;
  3. SET DATABASE = passwordless_demo;
  5. CREATE TABLE IF NOT EXISTS users (
  6.     id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  7.     email STRING UNIQUE,
  8.     username STRING UNIQUE
  9. );
  11. CREATE TABLE IF NOT EXISTS verification_codes (
  12.     id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  13.     user_id UUID NOT NULL REFERENCES users ON DELETE CASCADE,
  14.     created_at TIMESTAMPTZ NOT NULL DEFAULT now()
  15. );
  17. INSERT INTO users (email, username) VALUES
  18.     ('john@passwordless.local', 'john_doe');

這個指令碼建立了一個名為 passwordless_demo 的資料庫、兩個名為 users 和 verification_codes 的表，以及為了稍後測試而插入的一些假使用者。每個驗證程式碼都與使用者關聯並儲存建立時間，以用於去檢查驗證程式碼是否過期。

在另外的終端中使用 cockroach sql 命令去執行這個指令碼：

  1. cat schema.sql | cockroach sql --insecure

環境配置

需要配置兩個環境變數：SMTP_USERNAME 和 SMTP_PASSWORD，你可以從你的 mailtrap 帳戶中獲得它們。將在我們的程式中用到它們。

Go 依賴

我們需要下列的 Go 包：

◈ github.com/lib/pq[6]：它是 CockroachDB 使用的 postgres 驅動
◈ github.com/matryer/way[7]: 路由器
◈ github.com/dgrijalva/jwt-go[8]: JWT 實現
  1. go get -u github.com/lib/pq
  2. go get -u github.com/matryer/way
  3. go get -u github.com/dgrijalva/jwt-go

程式碼

初始化函式

建立 main.go 並且透過 init 函式裡的環境變數中取得一些配置來啟動。

  1. var config struct {
  2.     port        int
  3.     appURL      *url.URL
  4.     databaseURL string
  5.     jwtKey      []byte
  6.     smtpAddr    string
  7.     smtpAuth    smtp.Auth
  8. }
  10. func init() {
  11.     config.port, _ = strconv.Atoi(env("PORT", "80"))
  12.     config.appURL, _ = url.Parse(env("APP_URL", "http://localhost:"+strconv.Itoa(config.port)+"/"))
  13.     config.databaseURL = env("DATABASE_URL", "postgresql://root@127.0.0.1:26257/passwordless_demo?sslmode=disable")
  14.     config.jwtKey = []byte(env("JWT_KEY", "super-duper-secret-key"))
  15.     smtpHost := env("SMTP_HOST", "smtp.mailtrap.io")
  16.     config.smtpAddr = net.JoinHostPort(smtpHost, env("SMTP_PORT", "25"))
  17.     smtpUsername, ok := os.LookupEnv("SMTP_USERNAME")
  18.     if !ok {
  19.         log.Fatalln("could not find SMTP_USERNAME on environment variables")
  20.     }
  21.     smtpPassword, ok := os.LookupEnv("SMTP_PASSWORD")
  22.     if !ok {
  23.         log.Fatalln("could not find SMTP_PASSWORD on environment variables")
  24.     }
  25.     config.smtpAuth = smtp.PlainAuth("", smtpUsername, smtpPassword, smtpHost)
  26. }
  28. func env(key, fallbackValue string) string {
  29.     v, ok := os.LookupEnv(key)
  30.     if !ok {
  31.         return fallbackValue
  32.     }
  33.     return v
  34. }
◈ appURL 將去構建我們的 “魔法連結”。
◈ port 將要啟動的 HTTP 伺服器。
◈ databaseURL 是 CockroachDB 地址，我新增 /passwordless_demo 前面的資料庫地址去表示資料庫名字。
◈ jwtKey 用於簽名 JWT。
◈ smtpAddr 是 SMTP_HOST + SMTP_PORT 的聯合；我們將使用它去傳送郵件。
◈ smtpUsername 和 smtpPassword 是兩個必需的變數。
◈ smtpAuth 也是用於傳送郵件。

env 函式允許我們去獲得環境變數，不存在時傳回一個回退值。

主函式

  1. var db *sql.DB
  3. func main() {
  4.     var err error
  5.     if db, err = sql.Open("postgres", config.databaseURL); err != nil {
  6.         log.Fatalf("could not open database connection: %v\n", err)
  7.     }
  8.     defer db.Close()
  9.     if err = db.Ping(); err != nil {
  10.         log.Fatalf("could not ping to database: %v\n", err)
  11.     }
  13.     router := way.NewRouter()
  14.     router.HandleFunc("POST", "/api/users", jsonRequired(createUser))
  15.     router.HandleFunc("POST", "/api/passwordless/start", jsonRequired(passwordlessStart))
  16.     router.HandleFunc("GET", "/api/passwordless/verify_redirect", passwordlessVerifyRedirect)
  17.     router.Handle("GET", "/api/auth_user", authRequired(getAuthUser))
  19.     addr := fmt.Sprintf(":%d", config.port)
  20.     log.Printf("starting server at %s \n", config.appURL)
  21.     log.Fatalf("could not start server: %v\n", http.ListenAndServe(addr, router))
  22. }

首先，開啟資料庫連線。記得要載入驅動。

  1. import (
  2.     _ "github.com/lib/pq"
  3. )

然後，我們建立路由器並定義一些端點。對於無密碼流程來說，我們使用兩個端點：/api/passwordless/start 傳送魔法連結，和 /api/passwordless/verify_redirect 用 JWT 響應。

最後，我們啟動伺服器。

你可以建立空處理程式和中介軟體去測試伺服器啟動。

  1. func createUser(w http.ResponseWriter, r *http.Request) {
  2.     http.Error(w, http.StatusText(http.StatusNotImplemented), http.StatusNotImplemented)
  3. }
  5. func passwordlessStart(w http.ResponseWriter, r *http.Request) {
  6.     http.Error(w, http.StatusText(http.StatusNotImplemented), http.StatusNotImplemented)
  7. }
  9. func passwordlessVerifyRedirect(w http.ResponseWriter, r *http.Request) {
  10.     http.Error(w, http.StatusText(http.StatusNotImplemented), http.StatusNotImplemented)
  11. }
  13. func getAuthUser(w http.ResponseWriter, r *http.Request) {
  14.     http.Error(w, http.StatusText(http.StatusNotImplemented), http.StatusNotImplemented)
  15. }
  17. func jsonRequired(next http.HandlerFunc) http.HandlerFunc {
  18.     return func(w http.ResponseWriter, r *http.Request) {
  19.         next(w, r)
  20.     }
  21. }
  23. func authRequired(next http.HandlerFunc) http.HandlerFunc {
  24.     return func(w http.ResponseWriter, r *http.Request) {
  25.         next(w, r)
  26.     }
  27. }

接下來：

  1. go build
  2. ./passwordless-demo

我們在目錄中有了一個 “passwordless-demo”，但是你的目錄中可能與示例不一樣，go build 將建立一個同名的可執行檔案。如果你沒有關閉前面的 cockroach 節點，並且你正確配置了 SMTP_USERNAME 和 SMTP_PASSWORD 變數，你將看到命令 starting server at http://localhost/ 沒有錯誤輸出。

請求 JSON 的中介軟體

端點需要從請求體中解碼 JSON，因此要確保請求是 application/json 型別。因為它是一個通用的東西，我將它解耦到中介軟體。

  1. func jsonRequired(next http.HandlerFunc) http.HandlerFunc {
  2.     return func(w http.ResponseWriter, r *http.Request) {
  3.         ct := r.Header.Get("Content-Type")
  4.         isJSON := strings.HasPrefix(ct, "application/json")
  5.         if !isJSON {
  6.             respondJSON(w, "JSON body required", http.StatusUnsupportedMediaType)
  7.             return
  8.         }
  9.         next(w, r)
  10.     }
  11. }

實現很容易。首先它從請求頭中獲得內容的型別，然後檢查它是否是以 “application/json” 開始，如果不是則以 415 Unsupported Media Type 提前傳回。

響應 JSON 的函式

以 JSON 響應是非常通用的做法，因此我把它提取到函式中。

  1. func respondJSON(w http.ResponseWriter, payload interface{}, code int) {
  2.     switch value := payload.(type) {
  3.     case string:
  4.         payload = map[string]string{"message": value}
  5.     case int:
  6.         payload = map[string]int{"value": value}
  7.     case bool:
  8.         payload = map[string]bool{"result": value}
  9.     }
  10.     b, err := json.Marshal(payload)
  11.     if err != nil {
  12.         respondInternalError(w, fmt.Errorf("could not marshal response payload: %v", err))
  13.         return
  14.     }
  15.     w.Header().Set("Content-Type", "application/json; charset=utf-8")
  16.     w.WriteHeader(code)
  17.     w.Write(b)
  18. }

首先，對原始型別做一個型別判斷，並將它們封裝到一個 map。然後將它們編組到 JSON，設定響應內容型別和狀態碼，並寫 JSON。如果 JSON 編組失敗，則響應一個內部錯誤。

響應內部錯誤的函式

respondInternalError 是一個響應 500 Internal Server Error 的函式，但是也同時將錯誤輸出到控制檯。

  1. func respondInternalError(w http.ResponseWriter, err error) {
  2.     log.Println(err)
  3.     respondJSON(w,
  4.         http.StatusText(http.StatusInternalServerError),
  5.         http.StatusInternalServerError)
  6. }

建立使用者的處理程式

下麵開始編寫 createUser 處理程式，因為它非常容易並且是 REST 式的。

  1. type User struct {
  2.     ID       string `json:"id"`
  3.     Email    string `json:"email"`
  4.     Username string `json:"username"`
  5. }

User 型別和 users 表相似。

  1. var (
  2.     rxEmail = regexp.MustCompile("^[^\\s@]+@[^\\s@]+\\.[^\\s@]+$")
  3.     rxUsername = regexp.MustCompile("^[a-zA-Z][\\w|-]{1,17}$")
  4. )

這些正則運算式是分別用於去驗證電子郵件和使用者名稱的。這些都很簡單，可以根據你的需要隨意去適配。

現在，在 createUser 函式內部，我們將開始解碼請求體。

  1. var user User
  2. if err := json.NewDecoder(r.Body).Decode(&user); err != nil {
  3.     respondJSON(w, err.Error(), http.StatusBadRequest)
  4.     return
  5. }
  6. defer r.Body.Close()

我們將使用請求體去建立一個 JSON 解碼器來解碼出一個使用者指標。如果發生錯誤則傳回一個 400 Bad Request。不要忘記關閉請求體讀取器。

  1. errs := make(map[string]string)
  2. if user.Email == "" {
  3.     errs["email"] = "Email required"
  4. } else if !rxEmail.MatchString(user.Email) {
  5.     errs["email"] = "Invalid email"
  6. }
  7. if user.Username == "" {
  8.     errs["username"] = "Username required"
  9. } else if !rxUsername.MatchString(user.Username) {
  10.     errs["username"] = "Invalid username"
  11. }
  12. if len(errs) != 0 {
  13.     respondJSON(w, errs, http.StatusUnprocessableEntity)
  14.     return
  15. }

這是我如何做驗證；一個簡單的 map 並檢查如果 len(errs) != 0，則使用 422 Unprocessable Entity 去傳回。

  1. err := db.QueryRowContext(r.Context(), `
  2.     INSERT INTO users (email, username) VALUES ($1, $2)
  3.     RETURNING id
  4. `, user.Email, user.Username).Scan(&user.ID)
  6. if errPq, ok := err.(*pq.Error); ok && errPq.Code.Name() == "unique_violation" {
  7.     if strings.Contains(errPq.Error(), "email") {
  8.         errs["email"] = "Email taken"
  9.     } else {
  10.         errs["username"] = "Username taken"
  11.     }
  12.     respondJSON(w, errs, http.StatusForbidden)
  13.     return
  14. } else if err != nil {
  15.     respondInternalError(w, fmt.Errorf("could not insert user: %v", err))
  16.     return
  17. }

這個 SQL 查詢使用一個給定的 email 和使用者名稱去插入一個新使用者，並傳回自動生成的 id，每個 $ 將被接下來傳遞給 QueryRowContext 的引數替換掉。

因為 users 表在 email 和 username 欄位上有唯一性約束，因此我將檢查 “unique_violation” 錯誤並傳回 403 Forbidden 或者傳回一個內部錯誤。

  1. respondJSON(w, user, http.StatusCreated)

最後使用建立的使用者去響應。

無密碼驗證開始部分的處理程式

  1. type PasswordlessStartRequest struct {
  2.     Email       string `json:"email"`
  3.     RedirectURI string `json:"redirectUri"`
  4. }

這個結構體含有 passwordlessStart 的請求體：希望去登入的使用者 email、來自客戶端的重定向 URI（這個應用中將使用我們的 API）如：https://frontend.app/callback。

  1. var magicLinkTmpl = template.Must(template.ParseFiles("templates/magic-link.html"))

我們將使用 golang 模板引擎去構建郵件，因此需要你在 templates 目錄中，用如下的內容建立一個 magic-link.html 檔案：

  1. 

  2.  lang="en">
  4.      charset="utf-8">

<p style="word-wrap: break-word;margin-top: 1.5em;margin-bottom: 1.5em;line-height: 2em;">這些是如何去建立 JWT。我們為 JWT 設定一個 60 天的過期值，你也可以設定更短的時間（大約 2 周），並新增一個新端點去掃清令牌，但是不要搞的過於複雜。</p>
