我正在使用ktor v0.9.2,我想根据用户是否经过身份验证,为同一路由发送不同的内容。
我遇到的问题是我无法访问authenticate { }
区域以外的校长。
我的设置是这样的:
data class User(
val userId: Int
) : io.ktor.auth.Principal
fun Application.myApp() {
install(Authentication) {
jwt {
verifier(JwtConfig.verifier)
validate { credential ->
val userId = credential.payload.getClaim("userId").asInt()
when {
userId > 0 -> User(userId)
else -> null
}
}
}
}
install(DefaultHeaders)
install(CallLogging)
install(ContentNegotiation) {
jackson { }
}
install(Routing) {
authenticate {
get("/protected") {
// This works fine!!
val user = call.authentication.principal<User>()
call.respond(user)
}
}
get("/") {
val user = call.authentication.principal<User>() // -> User is always null here
if (user == null) {
call.respondText("Not Logged User")
} else {
call.respondText("Logged User")
}
}
}
}
/protected
路由正常,但在/
路由中,主体始终为空。我认为这是一些管道问题,但我有点失落。有人能提供一些见解吗?谢谢!
答案 0 :(得分:0)
您使用的是什么版本的ktor? 你能告诉我们你的auth设置吗?
你应该有这样的东西(0.9.2):
install(Authentication) {
jwt {
verifier(JwtConfig.verifier)
realm = JwtConfig.realm
validate {
val email = it.payload.getClaim("email").toString()
userRepository.findUser(email)?.let { user ->
val token = JwtConfig.makeToken(user)
user.copy(token = token)
}
}
}
}
如果验证过程成功,则用户将通过委托人获得。
这是0.9.3的更新代码。
从测试开始验证行为。
只需添加optional
标记。
class KtorTest {
@Test fun server() {
withTestApplication({ myApp() }) {
val userId = 918354853
val token = JwtConfig.makeToken(User(userId))
// The protected route
handleRequest {
uri = "/protected"
addHeader("Authorization", "Bearer $token")
}.let {
it.requestHandled shouldBe true
it.response.content.shouldNotBeNullOrBlank() shouldContain userId.toString()
}
// Optional route without token
handleRequest {}.let {
it.requestHandled shouldBe true
it.response.content.shouldNotBeNullOrBlank() shouldBeEqualTo "Not Logged User"
}
// Optional route with token
handleRequest {
addHeader("Authorization", "Bearer $token")
}.let {
it.requestHandled shouldBe true
it.response.content.shouldNotBeNullOrBlank() shouldBeEqualTo "Logged User"
}
}
}
}
data class User(val userId: Int) : Principal
fun Application.myApp() {
install(Authentication) {
jwt {
verifier(JwtConfig.verifier)
validate { credential ->
val userId = credential.payload.getClaim("userId").asInt()
when {
userId > 0 -> User(userId)
else -> null
}
}
}
}
install(DefaultHeaders)
install(CallLogging)
install(ContentNegotiation) { jackson { } }
install(Routing) {
authenticate {
get("/protected") {
// This works fine!!
val user = call.authentication.principal<User>()!!
call.respond(user)
}
}
authenticate(optional = true) {
get("/") {
val user = call.authentication.principal<User>() // -> User is always null here
if (user == null) {
call.respondText("Not Logged User")
} else {
call.respondText("Logged User")
}
}
}
}
}
