公司网关改造,使用 Apisix 替换原有的 Springcloud Gateway,原来网关上自带了一个接口
逻辑比较简单,配置文件中有一个开关:
{
"status": 200,
"message": "分享登录开关打开",
"data": true,
"rel": true
}
{
"status": 200,
"message": "分享登录开关关闭",
"data": false,
"rel": true
}
希望保留原有逻辑,将该接口编写在 Apisix 中(当然,可以随便找个服务,补充这个接口,然后路由到上面,但是这里不想破坏原有逻辑)
查看官网资料可以看到,Apisix 可以通过 public-api
插件对外暴露接口
但是开启插件必须要与授权插件一起使用,orz___
只能通过自己的方式绕过它了
这里开发一个 名为 api-test
的插件,用于对外公开一个接口
local ngx = ngx
local core = require("apisix.core")
local consumer_mod = require("apisix.consumer")
local schema = {
type = "object",
properties = {
},
}
local consumer_schema = {
type = "object",
properties = {
key = { type = "string" },
switch = {
type = "boolean",
default = false
},
},
required = {"key"},
}
local plugin_name = "api-test"
local _M = {
version = 0.1,
priority = 35,
type = 'auth',
name = plugin_name,
schema = schema,
consumer_schema = consumer_schema
}
function _M.check_schema(conf)
if schema_type == core.schema.TYPE_CONSUMER then
return core.schema.check(consumer_schema, conf)
else
return core.schema.check(schema, conf)
end
end
local function getSwitch()
local consumer_conf = consumer_mod.plugin(plugin_name)
if not consumer_conf then
return core.response.exit(404)
end
local consumers = consumer_mod.consumers_kv(plugin_name, consumer_conf, "key")
local consumer = consumers[plugin_name]
if not consumer then
return core.response.exit(401, "Consumer Key Should Be Equal To Plugin Name")
end
local switch_flag = consumer.auth_conf.switch
core.log.warn("consumer_conf: ", switch_flag)
local tbl = { status = 200 , rel = true }
if switch_flag then
tbl["message"] = "分享登录开关打开"
tbl["data"] = true
else
tbl["message"] = "分享登录开关关闭"
tbl["data"] = false
end
return core.response.exit(200, core.json.encode(tbl))
end
function _M.api()
return {
{
methods = {"GET"},
uri = "/switch/getSwitch",
handler = getSwitch,
}
}
end
return _M
核心代码,这里需要保证 consumer 的名称与插件名称相同即可通过校验
local consumer = consumers[plugin_name]
添加自定义插件可以参考:apisix 开发自定义插件
curl http://127.0.0.1:9180/apisix/admin/consumers \
-H 'X-API-KEY: ' -X PUT -d '
{
"username": "api-test",
"plugins": {
"api-test": {
"key": "api-test",
"switch": true
}
}
}'
curl -X PUT 'http://127.0.0.1:9180/apisix/admin/routes/r1' \
-H 'X-API-KEY: ' \
-H 'Content-Type: application/json' \
-d '{
"uri": "/switch/getSwitch",
"plugins": {
"public-api": {}
}
}'
如果需要改动 lua 脚本,可以通过以下指令 热加载
curl http://127.0.0.1:9180/apisix/admin/plugins/reload -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT
然后就可以测试接口了
curl 'http://127.0.0.1:9080/switch/getSwitch'
返回结果
{
"status": 200,
"message": "分享登录开关打开",
"rel": true,
"data": true
}
