-------------------------------------------------------------------------------- /nacos-tonic-discover/README.md: -------------------------------------------------------------------------------- 1 | 2 | # nacos-tonic-discover 3 | 4 | ## 介绍 5 | nacos_rust_client 对 tonic 服务地址选择器的适配 6 | 7 | ## 使用方式 8 | 9 | ```toml 10 | [dependencies] 11 | nacos-tonic-discover = "0.1" 12 | nacos_rust_client = "0.3" 13 | tonic = "0.7" 14 | ``` 15 | 16 | ### 地址选择器工厂 17 | 18 | 地址选择器工厂,背后会缓存channel,监听服务地址变更然后更新到channel。 19 | 20 | 1. 创建地址选择器工厂 21 | 22 | ```rust 23 | let discover_factory = TonicDiscoverFactory::new(naming_client.clone()); 24 | ``` 25 | 26 | 创建地址选择器工厂,后会把工厂的一个引用加入到全局对象,可以通过 `get_last_factory`获取. 27 | 28 | ```rust 29 | let discover_factory = nacos_tonic_discover::get_last_factory().unwrap();``` 30 | 31 | 2. 构建指定服务对应的 `tonic::transport::Channel` 32 | 33 | ```rust 34 | let service_key = ServiceInstanceKey::new("helloworld","AppName"); 35 | let channel = discover_factory.build_service_channel(service_key.clone()).await?; 36 | ``` 37 | 38 | 地址选择器工厂,背后会维护 `Channel`的最新有效地址;对同一个service_key实际只创建一个`Channel`,第一次构建，后续直接返回缓存拷贝。 39 | 40 | 3. 使用Channel创建service client,并使用 41 | 42 | ```rust 43 | let mut client = GreeterClient::new(channel); 44 | let request = tonic::Request::new(HelloRequest { 45 | name: format!("Tonic"), 46 | }); 47 | let response = client.say_hello(request).await?; 48 | ``` 49 | 50 | ## 例子 51 | 52 | 运行下面的例子，需要先启动nacos服务，把例子中的host改成实际的地址。 53 | 54 | 例子完整依赖与代码可以参考 examples/下的代码。 55 | 56 | 57 | 58 | 59 | ### tonic

-------------------------------------------------------------------------------- 1 | 2 | # nacos_rust_client 3 | 4 | ## 介绍 5 | rust实现的nacos客户端。 6 | 7 | nacos_rust_client是我在写[r-nacos](https://github.com/heqingpan/rnacos) (用rust重写的nacos服务)过程中实现的客户端，服务端与客户端相互验证，目前已比较稳定推荐使用。 8 | 9 | 0.3.x版本开始同时支持nacos `1.x`版http协议和`2.x`版本协议，支持在创建client时指定使用协议类型。 10 | 11 | 0.2.x版本只支持nacos `1.x`版http协议. 12 | 13 | 0.3.x版本兼容0.2版本api，建议使用nacos_rust_client都升级到0.3.x版本。 14 | 15 | 特点： 16 | 17 | 1. 使用 actix + tokio 实现。 18 | 2. 支持配置中心的推送、获取、监听。 19 | 3. 支持注册中心的服务实例注册(自动维护心跳)、服务实例获取(自动监听缓存实例列表)。 20 | 4. 创建的客户端后台处理，都放在同一个actix环境线程; 高性能，不会有线程膨胀，稳定可控。 21 | 22 | 23 | ## 使用方式 24 | 25 | 首先加入引用 26 | 27 | ```toml 28 | [dependencies] 29 | nacos_rust_client = "0.3" 30 | ``` 31 | 32 | ### 使用配置中心 33 | 34 | 1. 创建客户端 35 | 36 | 使用`ClientBuilder`创建配置客户端，支持设置集群地址列表，支持验权校验. 37 | 38 | ```rust 39 | use nacos_rust_client::client::config_client::ConfigClient; 40 | use nacos_rust_client::client::ClientBuilder; 41 | //... 42 | //兼容旧版本的创建方式，旧版本创建方式使用http协议 43 | //let config_client = ConfigClient::new_with_addrs("127.0.0.1:8848,127.0.0.1:8848",tenant,auth_info); 44 | let config_client = ClientBuilder::new() 45 | .set_endpoint_addrs("127.0.0.1:8848,127.0.0.1:8848") 46 | .set_auth_info(auth_info) 47 | .set_tenant(tenant) 48 | .set_use_grpc(true) //select communication protocol 49 | .build_config_client(); 50 | ``` 51 | 52 | 创建客户端,后会把客户端的一个引用加入到全局对象,可以通过 `get_last_config_client`获取. 53 | 54 | ```rust 55 | let config_client = nacos_rust_client::get_last_config_client().unwrap(); 56 | ``` 57 | 58 | 2. 设置获取配置信息 59 | 60 | ```rust 61 | let key = ConfigKey::new("data_id","group_name","" /*tenant_id*/); 62 | config_client.set_config(&key, "config_value").await.unwrap(); 63 | let v=config_client.get_config(&key).await.unwrap(); 64 | ``` 65 | 66 | 3. 配置监听器 67 | 68 | 实时的接收服务端的变更推送，更新监听器的内容，用于应用配置动态下发。 69 | 70 | ```rust 71 | #[derive(Debug,Serialize,Deserialize,Default,Clone)] 72 | pub struct Foo { 73 | pub name: String, 74 | pub number: u64, 75 | } 76 | //... 77 | let foo_config_obj_listener = Box::new(ConfigDefaultListener::new(key.clone(),Arc::new(|s|{ 78 | //字符串反序列化为对象，如:serde_json::from_str::(s) 79 | Some(serde_json::from_str::(s).unwrap()) 80 | }))); 81 | config_client.subscribe(foo_config_obj_listener.clone()).await; 82 | let foo_obj_from_listener = foo_config_obj_listener.get_value().unwrap(); 83 | ``` 84 | 85 | ### 使用注册中心 86 | 87 | 1. 创建客户端 88 | 89 | 使用`NamingClient::new_with_addrs`创建配置客户端，支持设置集群地址列表，支持验权校验. 90 | 91 | ```rust 92 | use nacos_rust_client::client::naming_client::NamingClient; 93 | use nacos_rust_client::client::ClientBuilder; 94 | //... 95 | //兼容旧版本的创建方式，旧版本创建方式使用http协议 96 | //let naming_client = NamingClient::new_with_addrs("127.0.0.1:8848,127.0.0.1:8848",namespace_id,auth_info); 97 | let naming_client = ClientBuilder::new() 98 | .set_endpoint_addrs("127.0.0.1:8848,127.0.0.1:8848") 99 | .set_auth_info(auth_info) 100 | .set_tenant(tenant) 101 | .set_use_grpc(true) //select communication protocol 102 | .build_naming_client(); 103 | ``` 104 | 105 | 创建客户端,后会把客户端的一个引用加入到全局对象,可以通过 `get_last_naming_client`获取. 106 | 107 | ```rust 108 | let naming_client = nacos_rust_client::get_last_naming_client().unwrap(); 109 | ``` 110 | 111 | 2. 注册服务实例 112 | 113 | 只要调拨一次注册实例，客户端会自动在后面维持心跳保活。 114 | 115 | ```rust 116 | let instance = Instance::new_simple(&ip,port,service_name,group_name); 117 | naming_client.register(instance); 118 | ``` 119 | 120 | 3. 服务地址路由 121 | 122 | 查询指定服务的地址列表 123 | 124 | ```rust 125 | let params = QueryInstanceListParams::new_simple(service_name,group_name); 126 | let instance_list_result=client.query_instances(params).await; 127 | ``` 128 | 129 | 查询指定服务的地址列表并按重选中一个地址做服务调用。 130 | 131 | ```rust 132 | let params = QueryInstanceListParams::new_simple(service_name,group_name); 133 | let instance_result=client.select_instance(params).await; 134 | ``` 135 | 136 | 如果要在tonic中使用服务地址选择,可以使用对tonic的适配 (nacos-tonic-discover)[https://crates.io/crates/nacos-tonic-discover] 137 | 138 | ### 其它 139 | 140 | 应用结束时，nacos_rust_client可能还有后台的调用，可以调用`nacos_rust_client::close_current_system()` 优雅退出nacos_rust_client后台线程。 141 | 142 | 143 | ## 例子 144 | 145 | 运行下面的例子，需要先启动nacos服务，把例子中的host改成实际的地址。 146 | 147 | 例子完整依赖与代码可以参考 examples/下的代码。 148 | 149 | 150 | ### 配置中心例子 151 | 152 | ```rust 153 |
