# LINGYUN.Abp.Dapr.Client |
||||
|
|
||||
|
实现了Dapr文档中的服务间调用,项目设计与Volo.Abp.Http.Client一致,通过配置文件即可无缝替代Volo.Abp.Http.Client |
||||
|
|
||||
|
配置参考 [AbpRemoteServiceOptions](https://docs.abp.io/zh-Hans/abp/latest/API/Dynamic-CSharp-API-Clients#abpremoteserviceoptions) |
||||
|
|
||||
|
## 配置使用 |
||||
|
|
||||
|
模块按需引用 |
||||
|
|
||||
|
```csharp |
||||
|
[DependsOn(typeof(AbpDaprClientModule))] |
||||
|
public class YouProjectModule : AbpModule |
||||
|
{ |
||||
|
public override void ConfigureServices(ServiceConfigurationContext context) |
||||
|
{ |
||||
|
// 注册代理类似于 Volo.Abp.Http.Client 模块 |
||||
|
context.Services.AddDaprClientProxies( |
||||
|
typeof(YouProjectActorInterfaceModule).Assembly, // 搜索 YouProjectActorInterfaceModule 模块下的远程服务定义 |
||||
|
RemoteServiceName |
||||
|
); |
||||
|
} |
||||
|
} |
||||
|
``` |
||||
|
## 配置项说明 |
||||
|
|
||||
|
* AbpDaprClientOptions.GrpcEndpoint Dapr暴露的Grpc端点, 对应 **DaprClientBuilder.GrpcEndpoint** |
||||
|
* AbpDaprClientOptions.HttpEndpoint Dapr暴露的Http端点, 对应 **DaprClientBuilder.HttpEndpoint** |
||||
|
* AbpDaprClientOptions.GrpcChannelOptions 通过Grpc调用远程服务的配置项, 对应 **DaprClientBuilder.GrpcChannelOptions** |
||||
|
|
||||
|
* AbpDaprRemoteServiceOptions.RemoteServices 配置Dapr.AppId |
||||
|
|
||||
|
```json |
||||
|
|
||||
|
{ |
||||
|
"Dapr": { |
||||
|
"Client": { |
||||
|
"HttpEndpoint": "http://127.0.0.1:50000" |
||||
|
} |
||||
|
}, |
||||
|
"RemoteServices": { |
||||
|
"System": { |
