Property Detail

shenyu.httpclient config

This is the HttpClient configuration used to send proxy requests after proxying the Http and SpringCloud protocols in the ShenYu gateway.

Name	Type	Default	Required	Description
strategy	String	webcwebClient	No	The strategy of httpClientPlugin
connectTimeout	int	45000	No	Connection timeout (millisecond), the default value is 45000.
readTimeout	int	3000	No	Read timeout (millisecond), the default value is 3000.
writeTimeout	int	3000	No	Write timeout (millisecond), the default value is 3000.
wiretap	Boolean	false	No	Enables wiretap debugging for Netty HttpClient, the default value is false.
pool				HttpClient connection pool config
proxy				HttpClient proxy config
ssl				HttpClient ssl config

• pool config

HttpClient connection pool configuration:

Name	Type	Default	Required	Description
type	String	ELASTIC	No	Type of pool for HttpClient to use, defaults to ELASTIC. - ELASTIC: The connection pool can be cached and grown on demand - FIXED: The connection pool cache and reuse a fixed maximum The number of connections. - DISABLED: The connection pool will always create a new connection.
