如何在 go 中测试验证 JWT 路由

Question

我想使用 JWT 身份验证测试受保护的路由。

已经尝试接收响应并尝试传递令牌，但它仅返回 401 作为代码响应。

package routes

import (
    "fmt"
    "github.com/stretchr/testify/assert"

    "net/http"
    "net/http/httptest"
    "testing"
)

func performRequest(r http.Handler, method, path string, t *testing.T) *httptest.ResponseRecorder {
    token := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6InJ1aWJsYWVzZUBnbWFpbC5jb20iLCJleHAiOjE1NTk0MjQxMjIsIm9yaWdfaWF0IjoxNTU5NDIwNTIyfQ.kdIRkLjRc63VQvDcHECId45_8rlCr8QlAmVBcEG2tlE"
    w := httptest.NewRecorder()
    req, _ := http.NewRequest(method, path, nil)
    req.Header.Set("Authorization", fmt.Sprintf("Bearer %v", token))
    r.ServeHTTP(w, req)

    assert.Equal(t, w.Code, http.StatusOK)
    return w
}

func TestStartRouter(t *testing.T) {
    // Assert we encoded correctly,
    // the request gives a 200
    // Perform a GET request with that handler.
    router := StartRouter()

    w := performRequest(router, "GET", "/",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "POST", "/api/v1/signin",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "POST", "/api/v1/signup",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "GET", "/user",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "GET", "/user/id",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "GET", "/customer",t)
    assert.Equal(t, http.StatusOK, w.Code)
    w = performRequest(router, "GET", "/customer/id",t)
    assert.Equal(t, http.StatusOK, w.Code)

}

现在当我运行 go test 时，我只得到代码 401，但想要得到 HTTP 响应代码 200。

只需使用验证您的令牌的函数，这是jwt-go的示例

func isValidToken(tokenString, yourSecret string) bool {
    token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
        if _, ok := token.Method.(*jwt.SigningMethodHMAC); !ok {
            return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
        }
        return []byte(yourSecret), nil
    })

    if claims, ok := token.Claims.(jwt.MapClaims); ok && token.Valid {
        return true
    }
    return false
}

当然，这取决于您使用的包，但我在处理程序中没有看到对令牌的任何测试。 它在标题内，但仅此而已。

也许您可以看看我如何为 JWT 包测试 JWT 包装器。 你可以在
