redirect
Summary#
Name#
URI redirect.
Attributes#
| Name | Type | Requirement | Default | Valid | Description |
|---|---|---|---|---|---|
| http_to_https | boolean | optional | false | When it is set to true and the request is HTTP, will be automatically redirected to HTTPS with 301 response code, and the URI will keep the same as client request. | |
| uri | string | optional | New URL which can contain Nginx variable, eg: /test/index.html, $uri/index.html. You can refer to variables in a way similar to ${xxx} to avoid ambiguity, eg: ${uri}foo/index.html. If you just need the original $ character, add \ in front of it, like this one: /\$foo/index.html. If you refer to a variable name that does not exist, this will not produce an error, and it will be used as an empty string. | ||
| ret_code | integer | optional | 302 | [200, ...] | Response code |
Only one of http_to_https or uri can be specified.
How To Enable#
Here's a mini example, enable the redirect plugin on the specified route:
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{ "uri": "/test/index.html", "plugins": { "redirect": { "uri": "/test/default.html", "ret_code": 301 } }, "upstream": { "type": "roundrobin", "nodes": { "127.0.0.1:80": 1 } }}'And we can use any Nginx built-in variable in the new URI.
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{ "uri": "/test", "plugins": { "redirect": { "uri": "$uri/index.html", "ret_code": 301 } }, "upstream": { "type": "roundrobin", "nodes": { "127.0.0.1:80": 1 } }}'Test Plugin#
Testing based on the above examples :
$ curl http://127.0.0.1:9080/test/index.html -iHTTP/1.1 301 Moved PermanentlyDate: Wed, 23 Oct 2019 13:48:23 GMTContent-Type: text/htmlContent-Length: 166Connection: keep-aliveLocation: /test/default.html
...We can check the response code and the response header Location.
It shows that the redirect plugin is in effect.
Here is an example of redirect HTTP to HTTPS:
curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '{ "uri": "/hello", "plugins": { "redirect": { "http_to_https": true } }}'Disable Plugin#
When you want to disable the redirect 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 '{ "uri": "/test/index.html", "plugins": {}, "upstream": { "type": "roundrobin", "nodes": { "127.0.0.1:80": 1 } }}'The redirect plugin has been disabled now. It works for other plugins.
