Service Configuration

Overview

This paper describes how to use the go-Zero framework for gRPC client development.

RpcClientConf

Name	DataType	Meaning	Default value	Required?
Etcd	EtcdConf	Service finds configuration, when using etcd for service discovery	None	NO
Endpoints	String Type Array	RPC Server address list, used for direct link, configured when required for a rpc server cluster	None	NO
Target	string	Domain URL solved, please refer to https://github.com/grpc/grpc/blob/master/doc/naming.md	None	NO
App	string	rpc authenticated app name, only configured when rpserver opens authentication	None	NO
Token	string	rpc authenticated token, only configured when rpserver opens authentication	None	NO
NonBlock	bool	Whether to block mode, when true does not block rpc links	false	NO
Timeout	int64	Timeout time	2000ms	NO
KeepaliveTime	Time.Duration	Keepalive Time	20s	NO
Middlewares	ClientMiddlewaresConf	Enable Middleware	None	NO

EtcdConf

EtcdConf config service discovery when using etcd for service discovery.

Name	DataType	Meaning	Default value	Required?

InsecureSkipVerify	bool	Whether or not to skip certificate verification	None	NO

ServerMiddlewaresConf

ServerMidlewaresConf is configured as an intermediary, when control is required.

Name	DataType	Meaning	Default value	Required?
