| 系统/工具/插件 | 版本 | 说明 |
|---|---|---|
| ubuntu | Linux version 5.3.0-46-generic (buildd@lcy01-amd64-013) (gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)) #38~18.04.1-Ubuntu SMP Tue Mar 31 04:17:56 UTC 2020 | cat /proc/version |
| consul | Consul v1.7.2 Protocol 2 spoken by default, understands 2 to 3 (agent will automatically use protocol >2 when speaking to compatible agents) |
consul version |
| micro | micro version 1.18.0 | micro --version |
创建一个service-srv【service】和一个service-web【client】
consul
consul agent -dev
1.srv
1.创建目录，剥离pb.go文件
mkdir -p $GOPATH/src/com/kokutas/www/pb
2.srv创建
创建service【srv】服务，并自定义命名空间com.kokutas.www【默认是go.micro】
服务名称的最后一级不要使用下划线，否则生成的handler/最后一级目录名.go中的服务还要做修改，【protobuf生成的时候的服务命名规则问题】
micro new --type srv --namespace com.kokutas.www com/kokutas/www/user
go get -u -v google.golang.org/grpc
go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
go get -u github.com/micro/protoc-gen-micro
3.修改.proto文件
修改$GOPATH/src/com/kokutas/www/user/proto/user.proto不然老是编译的时候提示警告信息
package com.kokutas.www.srv.user;
option go_package = "proto/user;com_kokutas_www_srv_user";
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第1张图片](http://img.e-com-net.com/image/info8/22347c7139c6469ea986b33d8dafa265.jpg)
4.进行编译.proto
cd $GOPATH/src/com/kokutas/www/user
tree $GOPATH/src/com/kokutas/www/
protoc --proto_path=.:$GOPATH/src --go_out=plugins=grpc:$GOPATH/src/com/kokutas/www/pb --micro_out=plugins=grpc:$GOPATH/src/com/kokutas/www/pb proto/user/user.proto
5.go mod init [*.pb.go目录]
方便后续导包异常的处理【将proto文件从本地导入(pb.go文件所在目录)】
tree $GOPATH/src/com/kokutas/www
cd $GOPATH/src/com/kokutas/www/pb/proto/user/ && go mod init com/kokutas/www/pb/proto/user && cd $GOPATH/src/com/kokutas/www/user
6.go mod why
explain why packages or modules are needed(解释为什么需要依赖)
cd $GOPATH/src/com/kokutas/www/user
go mod why
com/kokutas/www/user imports
com/kokutas/www/user/proto/user: package com/kokutas/www/user/proto/user is not in GOROOT (/usr/local/go/src/com/kokutas/www/user/proto/user)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第2张图片](http://img.e-com-net.com/image/info8/7cd9c376f1a24a398891d5970646e953.jpg)
7.修改go.mod 文件
修改$GOPATH/src/com/kokutas/www/user下的go.mod 文件
追加【本地只能是相对路径(=>后面的部分必须是相对路径),换行符不要动】
cd $GOPATH/src/com/kokutas/www/user
tee -a $GOPATH/src/com/kokutas/www/user/go.mod <<-'EOF'
// 添加是针对proto文件的本地包导入问题处理：只有这个能被go mod why检测到
require "com/kokutas/www/user/proto/user" v0.0.0
replace "com/kokutas/www/user/proto/user" => "../pb/proto/user"
// 针对的是consul和consul/api版本不一致的问题
replace github.com/hashicorp/consul => github.com/hashicorp/consul latest
replace github.com/hashicorp/consul/api => github.com/hashicorp/consul/api latest
// 针对的是micro 1.8.0的包路径改变问题：
replace github.com/golang/lint => golang.org/x/lint latest
// 在执行go get -u -v github.com/micor/micro下载的时候已经出现:
// go get: github.com/mholt/[email protected] updating to
// github.com/mholt/[email protected]: parsing go.mod:
// module declares its path as: github.com/caddyserver/certmagic
// but was required as: github.com/mholt/certmagic
replace github.com/testcontainers/testcontainer-go => github.com/testcontainers/testcontainers-go latest
EOF
说明【仅作说明不执行命令】：
// 针对的在执行go get -u -v github.com/micor/micro下载的时候的问题：
replace github.com/testcontainers/testcontainer-go => github.com/testcontainers/testcontainers-go latest
// go get: github.com/mholt/[email protected] updating to

replace github.com/hashicorp/consul => github.com/hashicorp/consul latest
replace github.com/hashicorp/consul/api => github.com/hashicorp/consul/api latest
go: found github.com/micro/go-plugins/registry/consul in github.com/micro/go-plugins v1.5.1
../../../../../pkg/mod/github.com/micro/[email protected]/registry/consul/consul.go:14:2: ambiguous import: found package github.com/hashicorp/consul/api in multiple modules:

github.com/hashicorp/consul/api v1.2.0 (/home/wyf/workspace/go/pkg/mod/github.com/hashicorp/consul/[email protected])
再次执行
go mod why
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第3张图片](http://img.e-com-net.com/image/info8/32dce681f5e74bf5a837ff27b09425cf.jpg)
8.go mod tidy
add missing and remove unused modules(拉取缺少的模块，移除不用的模块)
cd $GOPATH/src/com/kokutas/www/user
go mod tidy
9.go mod verify
verify dependencies have expected content (验证依赖是否正确）
cd $GOPATH/src/com/kokutas/www/user
go mod verify
10.go mod graph【选择性操作】
print module requirement graph (打印模块依赖图)
cd $GOPATH/src/com/kokutas/www/user
go mod graph
11.修改main.go
修改的是$GOPATH/src/com/kokutas/www/user/main.go
原main.go文件：
package main
import (
"com/kokutas/www/user/handler"
"com/kokutas/www/user/subscriber"
"github.com/micro/go-micro"
"github.com/micro/go-micro/util/log"
user "com/kokutas/www/user/proto/user"
)
func main() {
// New Service
service := micro.NewService(
micro.Name("com.kokutas.www.srv.user"),
micro.Version("latest"),
)
// Initialise service
service.Init()
// Register Handler
user.RegisterUserHandler(service.Server(), new(handler.User))
// Register Struct as Subscriber
micro.RegisterSubscriber("com.kokutas.www.srv.user", service.Server(), new(subscriber.User))
// Register Function as Subscriber
micro.RegisterSubscriber("com.kokutas.www.srv.user", service.Server(), subscriber.Handler)
// Run service
if err := service.Run(); err != nil {
log.Fatal(err)
}
}
1.修改为grpc创建服务
原service的创建：
// New Service
service := micro.NewService(
micro.Name("com.kokutas.www.srv.user"),
micro.Version("latest"),
)
使用grpc的service的创建：
导入的是下面的包：【务必不要导错】
“github.com/micro/go-micro/service/grpc”
// New Service
// grpc新建服务
service := grpc.NewService(
// 服务名称
micro.Name("com.kokutas.www.srv.user"),
// 服务版本
micro.Version("latest"),
)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第4张图片](http://img.e-com-net.com/image/info8/0523884c1b3e4b3c92157ac4cdb2d249.jpg)
2.添加consul支持
添加完grpc支持没有做consul支持：
// New Service
// grpc新建服务
service := grpc.NewService(
// 服务名称
micro.Name("com.kokutas.www.srv.user"),
// 服务版本
micro.Version("latest"),
)
添加完grpc支持做了consul支持：
导入的是下面的包：【务必不要导错】
“github.com/micro/go-micro/registry”
“github.com/micro/go-plugins/registry/consul”
// 新建consul注册器
consulReg := consul.NewRegistry(
// 注册的consul信息
registry.Addrs("127.0.0.1:8500"),
)
// New Service
// grpc新建服务
service := grpc.NewService(
// 服务名称
micro.Name("com.kokutas.www.srv.user"),
// 服务版本
micro.Version("latest"),
// 服务添加consul支持
micro.Registry(consulReg),
)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第5张图片](http://img.e-com-net.com/image/info8/2d2fb2f0825f428f9960233144269678.jpg)
修改后main.go文件：
package main
import (
"com/kokutas/www/user/handler"
"com/kokutas/www/user/subscriber"
"github.com/micro/go-micro"
// grpc支持的包，千万不要导错
"github.com/micro/go-micro/service/grpc"
"github.com/micro/go-micro/util/log"
// 调用的protobuf生成的包
user "com/kokutas/www/user/proto/user"
// 添加注册插件
"github.com/micro/go-micro/registry"
// 添加注册插件的consul支持
"github.com/micro/go-plugins/registry/consul"
)
func main() {
// 新建consul注册器
consulReg := consul.NewRegistry(
// 注册的consul信息
registry.Addrs("127.0.0.1:8500"),
)
// New Service
// grpc新建服务
service := grpc.NewService(
// 服务名称
micro.Name("com.kokutas.www.srv.user"),
// 服务版本
micro.Version("latest"),
// 服务添加consul支持
micro.Registry(consulReg),
)
// Initialise service
// 服务初始化
service.Init()
// Register Handler
// 注册句柄：服务和User结构体绑定
user.RegisterUserHandler(service.Server(), new(handler.User))
// Register Struct as Subscriber
// 注册订阅服务的结构体
micro.RegisterSubscriber("com.kokutas.www.srv.user", service.Server(), new(subscriber.User))
// Register Function as Subscriber
// 注册订阅服务的方法
micro.RegisterSubscriber("com.kokutas.www.srv.user", service.Server(), subscriber.Handler)
// Run service
// 启动服务
if err := service.Run(); err != nil {
log.Fatal(err)
}
}
12.启动srv
为了避免使用consul而发生无法发现服务的情况，在运行srv和web的时候建议都加上【–registry=consul】参数
即【go run main.go --registry=consul】
cd $GOPATH/src/com/kokutas/www/user
go run main.go
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第6张图片](http://img.e-com-net.com/image/info8/54c24196d7a8489c99bfae59e02e470d.jpg)
1.运行后undefined: grpc.Xxx报错
报错如下：
../pb/proto/user/user.pb.go:554:7: undefined: grpc.ClientConnInterface
../pb/proto/user/user.pb.go:558:11: undefined: grpc.SupportPackageIsVersion6
../pb/proto/user/user.pb.go:570:5: undefined: grpc.ClientConnInterface
../pb/proto/user/user.pb.go:573:23: undefined: grpc.ClientConnInterface
1.查看本机的proto-gen-go版本
cd $GOPATH/src/com/kokutas/www/user
go list -json github.com/golang/protobuf/protoc-gen-go
或者使用如下命令查看：
cd $GOPATH/src/com/kokutas/www/user
go list -json github.com/golang/protobuf/protoc-gen-go| grep Version
2.查看本机的grpc版本
cd $GOPATH/src/com/kokutas/www/user
go list -json google.golang.org/grpc
或者使用如下命令查看：
cd $GOPATH/src/com/kokutas/www/user
go list -json google.golang.org/grpc | grep Version
3.降低版本
go get -u -v github.com/golang/protobuf/[email protected]
4.重新编译
cd $GOPATH/src/com/kokutas/www/user
tree $GOPATH/src/com/kokutas/www/
protoc --proto_path=.:$GOPATH/src --go_out=plugins=grpc:$GOPATH/src/com/kokutas/www/pb --micro_out=plugins=grpc:$GOPATH/src/com/kokutas/www/pb proto/user/user.proto
2.再次启动srv
cd $GOPATH/src/com/kokutas/www/user
go run main.go
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第7张图片](http://img.e-com-net.com/image/info8/9cda3fb632f946429d7fabe6ab2edfe1.jpg)
3.报错缘故
设备上的grpc的版本是v1.25.1
设备上的protoc-gen-go的版本是v1.4.0
[email protected]要求grpc的版本是v1.27及以后的，所以将protoc-gen-go进行降低版本到能匹配[email protected]的即可。
13.go.mod
$GOPATH/src/com/kokutas/www/user/go.mod
module com/kokutas/www/user
go 1.14

2.web
1.web创建
新开一个终端，创建client【web】服务，并自定义命名空间com.kokutas.www【默认是go.micro】
cd $GOPATH/src
micro new --type web --namespace com.kokutas.www com/kokutas/www/web
2.go mod why
explain why packages or modules are needed(解释为什么需要依赖)
cd $GOPATH/src/com/kokutas/www/web
go mod why
go: finding module for package github.com/micro/go-micro/web
go: finding module for package github.com/micro/go-micro/util/log
go: finding module for package github.com/micro/go-micro/client

3.修改go.mod文件
修改$GOPATH/src/com/kokutas/www/web下的go.mod 文件
追加【本地只能是相对路径(=>后面的部分必须是相对路径),换行符不要动】
tee -a $GOPATH/src/com/kokutas/www/web/go.mod <<-'EOF'
// 添加是针对proto文件的本地包导入问题处理：只有这个能被go mod why检测到
require "path/to/service/proto/web" v0.0.0

replace github.com/testcontainers/testcontainer-go => github.com/testcontainers/testcontainers-go latest
EOF
说明【仅作说明不执行命令】：
// 针对的在执行go get -u -v github.com/micor/micro下载的时候的问题：

github.com/hashicorp/consul/api v1.2.0 (/home/wyf/workspace/go/pkg/mod/github.com/hashicorp/consul/[email protected])
再次执行
go mod why
4.go mod tidy
add missing and remove unused modules(拉取缺少的模块，移除不用的模块)
cd $GOPATH/src/com/kokutas/www/web
go mod tidy
5.go mod verify
verify dependencies have expected content (验证依赖是否正确）
cd $GOPATH/src/com/kokutas/www/web
go mod verify
6.go mod graph【选择性操作】
print module requirement graph (打印模块依赖图)
cd $GOPATH/src/com/kokutas/www/web
go mod graph
7.修改main.go
修改的是$GOPATH/src/com/kokutas/www/web/main.go
原main.go文件：
package main
import (
"net/http"
"github.com/micro/go-micro/util/log"
"com/kokutas/www/web/handler"
"github.com/micro/go-micro/web"
)
func main() {
// create new web service
service := web.NewService(
web.Name("com.kokutas.www.web.web"),
web.Version("latest"),
)
// initialise service
if err := service.Init(); err != nil {
log.Fatal(err)
}
// register html handler
service.Handle("/", http.FileServer(http.Dir("html")))
// register call handler
service.HandleFunc("/web/call", handler.WebCall)
// run service
if err := service.Run(); err != nil {
log.Fatal(err)
}
}
添加consul支持
原web服务【client】未做consul支持：
// create new web service
service := web.NewService(
web.Name("com.kokutas.www.web.web"),
web.Version("latest"),
)
web服务【client】做了consul支持：
导入的是下面的包：【务必不要导错】
“github.com/micro/go-micro/registry”
“github.com/micro/go-plugins/registry/consul”
// 新建consul注册器
consulReg := consul.NewRegistry(
// 注册的consul信息
registry.Addrs("127.0.0.1:8500"),
)
// create new web service
// 新建web服务
service := web.NewService(
// 服务名称
web.Name("com.kokutas.www.web.web"),
// 服务版本
web.Version("latest"),
// 服务添加consul支持
web.Registry(consulReg),
// 指定web服务端口号
web.Address(":8080"),
)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第9张图片](http://img.e-com-net.com/image/info8/b5b80fc762364068a3a64c6d2a746fd8.jpg)
修改后的main.go
package main
import (
"net/http"
"github.com/micro/go-micro/util/log"
"com/kokutas/www/web/handler"
"github.com/micro/go-micro/web"
// 添加注册插件
"github.com/micro/go-micro/registry"
// 添加注册插件的consul支持
"github.com/micro/go-plugins/registry/consul"
)
func main() {
// 新建consul注册器
consulReg := consul.NewRegistry(
// 注册的consul信息
registry.Addrs("127.0.0.1:8500"),
)
// create new web service
// 新建web服务
service := web.NewService(
// 服务名称
web.Name("com.kokutas.www.web.web"),
// 服务版本
web.Version("latest"),
// 服务添加consul支持
web.Registry(consulReg),
// 指定web服务端口号
web.Address(":8080"),
)
// initialise service
// 服务初始化
if err := service.Init(); err != nil {
log.Fatal(err)
}
// register html handler
// 注册静态资源处理句柄
service.Handle("/", http.FileServer(http.Dir("html")))
// register call handler
// 注册/web/call服务请求处理句柄
service.HandleFunc("/web/call", handler.WebCall)
// run service
// 启动服务
if err := service.Run(); err != nil {
log.Fatal(err)
}
}
8.修改handler/handler.go
修改$GOPATH/src/com/kokutas/www/web/handler/handler.go
原handler/handler.go文件：
package handler
import (
"context"
"encoding/json"
"net/http"
"time"
web "path/to/service/proto/web"
"github.com/micro/go-micro/client"
)
func WebCall(w http.ResponseWriter, r *http.Request) {
// decode the incoming request as json
var request map[string]interface{}
if err := json.NewDecoder(r.Body).Decode(&request); err != nil {
http.Error(w, err.Error(), 500)
return
}
// call the backend service
webClient := web.NewWebService("com.kokutas.www.srv.web", client.DefaultClient)
rsp, err := webClient.Call(context.TODO(), &web.Request{
Name: request["name"].(string),
})
if err != nil {
http.Error(w, err.Error(), 500)
return
}
// we want to augment the response
response := map[string]interface{}{
"msg": rsp.Msg,
"ref": time.Now().UnixNano(),
}
// encode and write the response as json
if err := json.NewEncoder(w).Encode(response); err != nil {
http.Error(w, err.Error(), 500)
return
}
}
修改为grpc创建服务【客户端】
原service服务【客户端】的创建：
// call the backend service
webClient := web.NewWebService("com.kokutas.www.srv.web", client.DefaultClient)
rsp, err := webClient.Call(context.TODO(), &web.Request{
Name: request["name"].(string),
})
if err != nil {
http.Error(w, err.Error(), 500)
return
}
使用grpc的service服务【客户端】的创建：
导入的是下面的包：【务必不要导错，且要和srv的 导包一致】
“github.com/micro/go-micro/service/grpc”
// 使用grpc创建客户端服务
cli := grpc.NewService()
// 客户端服务初始化
cli.Init()
// 基于后端服务com.kokutas.www.srv.user创建web客户端
// NewUserService要和pb/protobuf/user/user.pb.micro.go的NewUserService方法名一致
// com.kokutas.www.srv.user也要和pb/protobuf/user/user.pb.micro.go的com.kokutas.www.srv.user的一致
webClient := web.NewUserService("com.kokutas.www.srv.user", cli.Client())
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第10张图片](http://img.e-com-net.com/image/info8/c1246a14d4a34f90abdb94c6605980a4.jpg)
修改后的handler/handler.go文件
package handler
import (
"context"
"encoding/json"
"net/http"
"time"
web "path/to/service/proto/web"
"github.com/micro/go-micro/service/grpc"
)
func WebCall(w http.ResponseWriter, r *http.Request) {
// decode the incoming request as json
var request map[string]interface{}
if err := json.NewDecoder(r.Body).Decode(&request); err != nil {
http.Error(w, err.Error(), 500)
return
}
// 使用grpc创建客户端服务
cli := grpc.NewService()
// 客户端服务初始化
cli.Init()
// 基于后端服务com.kokutas.www.srv.user创建web客户端
// NewUserService要和pb/protobuf/user/user.pb.micro.go的NewUserService方法名一致
// com.kokutas.www.srv.user也要和pb/protobuf/user/user.pb.micro.go的com.kokutas.www.srv.user的一致
webClient := web.NewUserService("com.kokutas.www.srv.user", cli.Client())
// call the backend service
// 客户端调用后端服务
rsp, err := webClient.Call(context.TODO(), &web.Request{
Name: request["name"].(string),
})
if err != nil {
http.Error(w, err.Error(), 500)
return
}
// we want to augment the response
response := map[string]interface{}{
"msg": rsp.Msg,
"ref": time.Now().UnixNano(),
}
// encode and write the response as json
if err := json.NewEncoder(w).Encode(response); err != nil {
http.Error(w, err.Error(), 500)
return
}
}
9.启动web
为了避免使用consul而发生无法发现服务的情况，在运行srv和web的时候建议都加上【–registry=consul】参数
即【go run main.go --registry=consul】
cd $GOPATH/src/com/kokutas/www/web/
go run main.go
10.go.mod
$GOPATH/src/com/kokutas/www/web/go.mod
module com/kokutas/www/web
go 1.14
require github.com/micro/go-micro v1.18.0
require (
github.com/micro/go-plugins v1.5.1 // indirect
// 添加是针对proto文件的本地包导入问题处理：只有这个能被go mod why检测到
path/to/service/proto/web v0.0.0
)
replace path/to/service/proto/web => ../pb/proto/user
// 针对的是consul和consul/api版本不一致的问题
replace github.com/hashicorp/consul => github.com/hashicorp/consul v1.7.2
replace github.com/hashicorp/consul/api => github.com/hashicorp/consul/api v1.4.0
// 针对的是micro 1.8.0的包路径改变问题：
replace github.com/golang/lint => golang.org/x/lint v0.0.0-20200302205851-738671d3881b
// 在执行go get -u -v github.com/micor/micro下载的时候已经出现:
// go get: github.com/mholt/[email protected] updating to
//github.com/mholt/[email protected]: parsing go.mod:
//module declares its path as: github.com/caddyserver/certmagic
// but was required as: github.com/mholt/certmagic
replace github.com/testcontainers/testcontainer-go => github.com/testcontainers/testcontainers-go v0.5.1
3.访问
1.consul web访问
浏览器打开：
http://127.0.0.1:8500
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第11张图片](http://img.e-com-net.com/image/info8/352aac4e05c04c318fcba0b635b33a47.jpg)
2.web service 访问
http://127.0.0.1:8080
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第12张图片](http://img.e-com-net.com/image/info8/2551ceeb2d044021b42a3d5fbe9c86d5.jpg)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第13张图片](http://img.e-com-net.com/image/info8/f736caf664884f11ac7f2d0e8c6b10a2.jpg)
1.未进行输出报500异常处理
1.打印异常信息
修改$GOPATH/src/com/kokutas/www/web/handler/handler.go
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第14张图片](http://img.e-com-net.com/image/info8/9bc39339eff74295816b443acbe03b4c.jpg)
2.添加错误打印并重启web
重启web服务后，再次进行交互测试
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第15张图片](http://img.e-com-net.com/image/info8/d583bc9f53e840bd9e8fd94401bcc9a3.jpg)
3.解决
重启web服务，重启的命令进行修改
go run main.go --registry=consul
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第16张图片](http://img.e-com-net.com/image/info8/6708b53a1f524d95afcfd61dc1c18fbe.jpg)
![Microservice(八)[微服务-micro-consul-protobuf-gRPC-ubuntu]_第17张图片](http://img.e-com-net.com/image/info8/1679e7300a8046a4910350513e3733bf.jpg)
2.异常缘由
因为micro已经不再将consul作为默认的服务发现，改而用mdns和etcd，所以不添加此–registry=consul参数运行，并不能发现srv服务，从而无法进行交互。
所以，为了避免异常，在运行srv和web的时候建议都加上【–registry=consul】参数
