同步操作将从 iresty/Apache APISIX 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!

There are two plug-ins for serverless, namely serverless-pre-function
and serverless-post-function
.
The former runs at the beginning of the specified phase, while the latter runs at the end of the specified phase.
Both plug-ins receive the same parameters.
Name | Type | Requirement | Default | Valid | Description |
---|---|---|---|---|---|
phase | string | optional | ["access"] | ["rewrite", "access", "header_filter", "body_filter", "log", "balancer"] | |
functions | array[string] | required | A list of functions that are specified to run is an array type, which can contain either one function or multiple functions, executed sequentially. |
Note that only function is accepted here, not other types of Lua code. For example, anonymous functions are legal:
return function()
ngx.log(ngx.ERR, 'one')
end
Closure is also legal:
local count = 1
return function()
count = count + 1
ngx.say(count)
end
But code that is not a function type is illegal:
local count = 1
ngx.say(count)
Here's an example, enable the serverless plugin on the specified route:
curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"plugins": {
"serverless-pre-function": {
"phase": "rewrite",
"functions" : ["return function() ngx.log(ngx.ERR, \"serverless pre function\"); end"]
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
Use curl to access:
curl -i http://127.0.0.1:9080/index.html
Then you will find the message 'serverless pre-function' in the error.log, which indicates that the specified function is in effect.
When you want to disable the serverless plugin, it is very simple, you can delete the corresponding json configuration in the plugin configuration, no need to restart the service, it will take effect immediately:
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"methods": ["GET"],
"uri": "/index.html",
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
The serverless plugin has been disabled now. It works for other plugins.
