,可以通过以下步骤实现:
handleError
方法来捕获异常并进行处理。import org.http4s._
import org.http4s.dsl._
import org.http4s.server.blaze.BlazeBuilder
import org.http4s.server.{Server, ServerApp}
import org.http4s.util.StreamApp
object MyServer extends StreamApp {
val service = HttpService {
case GET -> Root / "hello" =>
// 业务逻辑处理
Ok("Hello, World!")
}
def stream(args: List[String]): fs2.Stream[Task, StreamApp.ExitCode] =
BlazeBuilder.bindHttp(8080, "localhost")
.mountService(service, "/")
.serve
}
req.uri
来获取请求的URL。import org.http4s._
import org.http4s.dsl._
import org.http4s.server.blaze.BlazeBuilder
import org.http4s.server.{Server, ServerApp}
import org.http4s.util.StreamApp
object MyServer extends StreamApp {
val service = HttpService {
case GET -> Root / "hello" =>
// 业务逻辑处理
Ok("Hello, World!")
case req @ GET -> Root / "error" =>
// 模拟InternalServerError异常
InternalServerError("Something went wrong")
// 记录请求的URL
val url = req.uri.toString
// 进行日志记录或其他处理
}
def stream(args: List[String]): fs2.Stream[Task, StreamApp.ExitCode] =
BlazeBuilder.bindHttp(8080, "localhost")
.mountService(service, "/")
.serve
}
在上述代码中,当请求的URL为/error
时,会触发InternalServerError异常,并记录请求的URL。
注意:以上代码仅为示例,实际使用时需要根据具体的业务需求进行适当的修改和扩展。
