使用Spray 1.3.1,我定义了Route
,如下所示:
val route: Route =
pathPrefix("v1" / "myapi") {
(path(Segment / Segment) & parameter("page".as[Int].?) & get) { (a, b, page) =>
...
} ~
(path(Segment / Segment) & entity(as[String]) & parameter("timer".as[Int].?) & put) { (a, b, body, timer) =>
...
} ~
(path(Segment / Segment) & delete) { (a, b) =>
...
}
}
现在,当我使用一堆字母作为Int
的解组参数时,我去测试错误时,我得到了我对GET
请求的期望:< / p>
$ curl -v -1 -X GET http://127.0.0.1:1234/v1/myapi/foo/bar?page="lalala"
...
< HTTP/1.1 400 Bad Request
...
'lalala' is not a valid 32-bit integer value
但是当我再次尝试PUT
时,会发生这种情况:
$ curl -v -1 -H "Content-Type:application/json;charset=utf-8" -X PUT -d '{"items": ["stuff", "stuff", "stuff"]}' http://127.0.0.1:1234/v1/myapi/foo/bar?timer="lalala"
...
< HTTP/1.1 405 Method Not Allowed
...
HTTP method not allowed, supported methods: GET, DELETE
这笔交易是什么?我应该补充说,如果数字格式正确,它会被解析并使用得很好。
答案 0 :(得分:4)
您应该在参数指令之前在路径匹配器中移动相应的方法指令,例如:
(put & path(Segment / Segment) & entity(as[String]) & parameter("timer".as[Int].?)) { (a, b, body, timer) =>
...
}
或者,而不是&amp;运营商,您也可以使用嵌套来组成路线:
val route: Route =
pathPrefix("v1" / "myapi") {
get {
(path(Segment / Segment) & parameter("page".as[Int].?)) { (a, b, page) =>
...
}
} ~ put {
(path(Segment / Segment) & entity(as[String]) & parameter("timer".as[Int].?)) { (a, b, body, timer) =>
...
}
} ~ delete {
(path(Segment / Segment)) { (a, b) =>
...
}
}
}
