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!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。
There are new requirements for API gateways in the field of microservices: higher flexibility, higher performance requirements, and cloud native.
APISIX is based on etcd to save and synchronize configuration, not relational databases such as Postgres or MySQL.
This not only eliminates polling, makes the code more concise, but also makes configuration synchronization more real-time. At the same time, there will be no single point in the system, which is more usable.
In addition, APISIX has dynamic routing and hot loading of plug-ins, which is especially suitable for API management under micro-service system.
One of the goals of APISIX design and development is the highest performance in the industry. Specific test data can be found here:benchmark
APISIX is the highest performance API gateway with a single-core QPS of 23,000, with an average delay of only 0.6 milliseconds.
Yes, in version 0.6 we have dashboard built in, you can operate APISIX through the web interface.
Of course, APISIX provides flexible custom plugins for developers and businesses to write their own logic.
For the configuration center, configuration storage is only the most basic function, and APISIX also needs the following features:
See more etcd why.
There are two possibilities when encountering slow luarocks:
For the first problem, you can use https_proxy or use the --server
option to specify a luarocks server that you can access or access faster.
Run the luarocks config rocks_servers
command(this command is supported after luarocks 3.0) to see which server are available.
If using a proxy doesn't solve this problem, you can add --verbose
option during installation to see exactly how slow it is. Excluding the first case, only the second that the git
protocol is blocked. Then we can run git config --global url."https://".insteadOf git://
to using the 'HTTPS' protocol instead of git
.
An example, foo.com/product/index.html?id=204&page=2
, gray release based on id
in the query string in URL as a condition:
here is the way:
curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"vars": [
["arg_id", "<=", "1000"]
],
"plugins": {
"redirect": {
"uri": "/test?group_id=1"
}
}
}'
curl -i http://127.0.0.1:9080/apisix/admin/routes/2 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/index.html",
"vars": [
["arg_id", ">", "1000"]
],
"plugins": {
"redirect": {
"uri": "/test?group_id=2"
}
}
}'
Here is the operator list of current lua-resty-radixtree
:
https://github.com/iresty/lua-resty-radixtree#operator-list
An example, redirect http://foo.com
to https://foo.com
There are several different ways to do this.
http_to_https
in redirect
plugin:curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/hello",
"host": "foo.com",
"plugins": {
"redirect": {
"http_to_https": true
}
}
}'
vars
with redirect
plugin:curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/hello",
"host": "foo.com",
"vars": [
[
"scheme",
"==",
"http"
]
],
"plugins": {
"redirect": {
"uri": "https://$host$request_uri",
"ret_code": 301
}
}
}'
serverless
plugin:curl -i http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"uri": "/hello",
"plugins": {
"serverless-pre-function": {
"phase": "rewrite",
"functions": ["return function() if ngx.var.scheme == \"http\" and ngx.var.host == \"foo.com\" then ngx.header[\"Location\"] = \"https://foo.com\" .. ngx.var.request_uri; ngx.exit(ngx.HTTP_MOVED_PERMANENTLY); end; end"]
}
}
}'
Then test it to see if it works:
curl -i -H 'Host: foo.com' http://127.0.0.1:9080/hello
The response body should be:
HTTP/1.1 301 Moved Permanently
Date: Mon, 18 May 2020 02:56:04 GMT
Content-Type: text/html
Content-Length: 166

This is an OS incompatible issue, you could fix by these two steps
brew edit openresty/brew/openresty
\ -fno-stack-check
in with-luajit-xcflags line.The default log level for APISIX is warn
. However You can change the log level to info
if you want to trace the messages print by core.log.info
.
Steps:
Modify the parameter error_log_level: "warn"
to error_log_level: "info"
in conf/config.yaml
Restart APISIX
Now you can trace the info level log in logs/error.log.
The Apache APISIX plugin supports hot reloading. If your APISIX node has the Admin API turned on, then for scenarios such as adding / deleting / modifying plugins, you can hot reload the plugin by calling the HTTP interface without restarting the service.
curl http://127.0.0.1:9080/apisix/admin/plugins/reload -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT
If your APISIX node does not open the Admin API, then you can manually load the plug-in by reloading APISIX.
apisix reload
