| ## 描述 |
| |
| `dubbo-proxy` 插件允许将 `HTTP` 请求代理到 [**dubbo**](http://dubbo.apache.org)。 |
| |
| ## 要求 |
| |
| 如果你正在使用 `OpenResty`, 你需要编译它来支持 `dubbo`, 参考 [APISIX-Runtime](../FAQ.md#如何构建-apisix-runtime-环境)。 |
| |
| ## 运行时属性 |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| | ------------ | ------ | ----------- | -------- | ------------ | -------------------------------------------------------------------- | |
| | service_name | string | 必选 | | | dubbo 服务名字 | |
| | service_version | string | 必选 | | | dubbo 服务版本 | |
| | method | string | 可选 | uri 路径 | | dubbo 服务方法 | |
| |
| ## 静态属性 |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| | ------------ | ------ | ----------- | -------- | ------------ | -------------------------------------------------------------------- | |
| | upstream_multiplex_count | number | 必选 | 32 | >= 1 | 上游连接中最大的多路复用请求数 | |
| |
| ## 如何启用 |
| |
| 首先,在 `config.yaml` 中启用 `dubbo-proxy` 插件: |
| |
| ``` |
| # Add this in config.yaml |
| plugins: |
| - ... # plugin you need |
| - dubbo-proxy |
| ``` |
| |
| 然后重载 `APISIX`。 |
| |
| 这里有个例子,在指定的路由中启用 `dubbo-proxy` 插件: |
| |
| :::note |
| |
| 您可以这样从 `config.yaml` 中获取 `admin_key` 并存入环境变量: |
| |
| ```bash |
| admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g') |
| ``` |
| |
| ::: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/upstreams/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "nodes": { |
| "127.0.0.1:20880": 1 |
| }, |
| "type": "roundrobin" |
| }' |
| |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "uris": [ |
| "/hello" |
| ], |
| "plugins": { |
| "dubbo-proxy": { |
| "service_name": "org.apache.dubbo.sample.tengine.DemoService", |
| "service_version": "0.0.0", |
| "method": "tengineDubbo" |
| } |
| }, |
| "upstream_id": 1 |
| }' |
| ``` |
| |
| ## 测试插件 |
| |
| 你可以在 `Tengine` 提供的 [快速开始](https://github.com/alibaba/tengine/tree/master/modules/mod_dubbo#quick-start) 例子中使用上述配置进行测试。 |
| |
| 将会有同样的结果。 |
| |
| 从上游 `dubbo` 服务返回的数据一定是 `Map<String, String>` 类型。 |
| |
| 如果返回的数据如下 |
| |
| ```json |
| { |
| "status": "200", |
| "header1": "value1", |
| "header2": "valu2", |
| "body": "blahblah" |
| } |
| ``` |
| |
| 则对应的 `HTTP` 响应如下 |
| |
| ```http |
| HTTP/1.1 200 OK # "status" will be the status code |
| ... |
| header1: value1 |
| header2: value2 |
| ... |
| |
| blahblah # "body" will be the body |
| ``` |
| |
| ## 删除插件 |
| |
| 当你想在某个路由或服务中禁用 `dubbo-proxy` 插件,非常简单,你可以直接删除插件配置中的 `json` 配置,不需要重启服务就能立即生效: |
| |
| ```shell |
| $ curl http://127.0.0.1:9180/apisix/admin/routes/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "methods": ["GET"], |
| "uris": [ |
| "/hello" |
| ], |
| "plugins": { |
| }, |
| "upstream_id": 1 |
| } |
| }' |
| ``` |
| |
| 现在 `dubbo-proxy` 插件就已经被禁用了。此方法同样适用于其他插件。 |
| |
| 如果你想彻底禁用 `dubbo-proxy` 插件, |
| 你需要在 `config.yaml` 中注释掉以下内容: |
| |
| ```yaml |
| plugins: |
| - ... # plugin you need |
| #- dubbo-proxy |
| ``` |
| |
| 然后重新加载 `APISIX`。 |
