preface

Only by understanding the configuration of the gateway can we understand what can be done with the gateway, so that it can be better applied in product development.

The yml configuration written below refers to the configuration written in the configuration file, and the JSON configuration refers to the configuration using dynamic routing, where there is a database or nacos.

1. Predicates

The main role of Predicates is to configure rules for routing matching requests

1. Http-related

Path configuration matching rules for the request path

2. Cookie configuration pair

The first value in the cookie is key, and the second is value. The following example matches the cookie settingschocolate:ch.prequest

3. Header matching

The content set in the http request, http-header can be matched by setting X-Request-Id:\d+, and the second parameter is a regular expression

4. Host matching

http request host, matching all hosts**.somehost.comrequest

5. Method matches the Http request header

6. Query matching

The query parameter in the HTTP request can be matched by the request with param1=value in the request

7. RemoteAddr matching

RemoteAddr in the request

8. Time correlation

After setting the time, it can be accessed

Beforecan be accessed before setting the time

Before

9. Weight routing

At least two groups of routes can be configured with weight routes, and several routes will be randomly accessed based on the weights


2. Filters

1. Path rewriting

2. Modify the request header

3. Modify the request parameters

4. Modify the response parameters

5. Path prefix enhancement

6. Delete the path prefix

7. Request to keep the original host

8. Redirect

9. Circuit breaker

10. Integrate Redis native support request throttling

11. Delete the request header attribute

12. Delete the response header attribute

13. Rewrite the response header

14. Reset the request path

15. Set the response head

In the next process, change the response header X-Response-Foo to Bar

16. Set the HTTP status

17. Set the file transfer size

18. Fail and try again
