我已经用声明性的方式配置了kong。我的服务和路线已配置为。
services:
- name: mock-service
url: http://mockbin.org/request
path: /
tags:
- example
routes:
- name: mock-route
methods:
- GET
hosts: ["mockbin.org"]
paths: ["/mock"]
我的服务和路线已注册，我可以看到响应为

finally i am able to resolve it.
sol :-
enter code here
#------------------------------------------------------------------------------
# DNS RESOLVER
#------------------------------------------------------------------------------
# By default the DNS resolver will use the standard configuration files
# `/etc/hosts` and `/etc/resolv.conf`. The settings in the latter file will be
# overridden by the environment variables `LOCALDOMAIN` and `RES_OPTIONS` if
# they have been set.
#
# Kong will resolve hostnames as either `SRV` or `A` records (in that order, and
# `CNAME` records will be dereferenced in the process).
# In case a name was resolved as an `SRV` record it will also override any given
# port number by the `port` field contents received from the DNS server.
#
# The DNS options `SEARCH` and `NDOTS` (from the `/etc/resolv.conf` file) will
# be used to expand short names to fully qualified ones. So it will first try
# the entire `SEARCH` list for the `SRV` type, if that fails it will try the
# `SEARCH` list for `A`, etc.
#
# For the duration of the `ttl`, the internal DNS resolver will load balance each
# request it gets over the entries in the DNS record. For `SRV` records the
# `weight` fields will be honored, but it will only use the lowest `priority`
# field entries in the record.

我遇到了同样的问题，并通过以下方式解决： 我正在使用以下配置： kong.yml
services:
- name: userapi-service
url: http://localhost:8082/userapi
tags:
- userapi
routes:
- name: userapi-route
paths:
- /userapi
访问http://localhost:8001/services
时进入下方{
"next": null,
"data": [
{
"host": "localhost",
"created_at": 1584710150,
"connect_timeout": 60000,
"id": "973c6d1e-b31b-5453-8424-20ad70a0c6c2",
"protocol": "http",
"name": "userapi-service",
"read_timeout": 60000,
"port": 8082,
"path": "/userapi",
"updated_at": 1584710150,
"client_certificate": null,
"tags": [
"userapi"
],
"write_timeout": 60000,
"retries": 5
}
]
}
以及访问路由时的以下内容：http://localhost:8001/services/userapi-service/routes
{
"next": null,
"data": [
{
"id": "3ba059ab-673e-5c4e-9eb6-eb5aa3437476",
"path_handling": "v0",
"paths": [
"/"
],
"destinations": null,
"headers": null,
"protocols": [
"http",
"https"
],
"created_at": 1584710150,
"snis": null,
"service": {
"id": "973c6d1e-b31b-5453-8424-20ad70a0c6c2"
},
"name": "userapi-route",
"tags": null,
"preserve_host": false,
"regex_priority": 0,
"strip_path": true,
"sources": null,
"updated_at": 1584710150,
"https_redirect_status_code": 426,
"hosts": [
"example.com"
],
"methods": null
}
]
}
并使用http://localhost:8000/-标头主机：example.com，并使用我的api调用的相对路径：http://localhost:8000/userapi/xxxxx/xxxx
