# 新增接口 假设要对下面这个接口提供开放能力。 ```java @RestController public class StoryDemoController { @RequestMapping("/story/get") public StoryResult getStory() { StoryResult result = new StoryResult(); result.setId(1L); result.setName("海底小纵队"); return result; } } ``` 只需要在方法上新增一个`@Open`注解，指定接口名即可 ```java // 添加一个@Open注解 @Open("story.demo.get") @RequestMapping("/story/get") public StoryResult getStory() { StoryResult result = new StoryResult(); result.setId(1L); result.setName("海底小纵队"); return result; } ``` 如果要加上版本号，指定`version`参数：`@Open(value = "story.demo.get", version = "2.0")` - 重启服务，这样接口就可以使用了。 ## 绑定业务参数 网关校验通过后，请求参数会传递到微服务上来，完整的参数如下所示： ``` 请求参数：charset=utf-8&biz_content={"goods_remark":"iphone6"}&method=goods.add&format=json&app_id=2019032617262200001&sign_type=RSA2&version=1.0×tamp=2019-04-29 19:18:38 ``` 其中biz_content部分是我们想要的，在方法上申明一个对象，对应biz_content中的内容即可完成参数绑定，并且对参数进行JSR-303校验。 **注意：接口方法必须有且只有一个对象参数，如果申明多个会出现参数绑定失败** ```java @Open("goods.add") @RequestMapping("/goods/add") public Object addGoods(GoodsParam param) { return param; } @Data public class GoodsParam { @NotEmpty(message = "不能为空") // 支持JSR-303校验 private String goods_remark; } ``` 一般情况下，只需要获取业务参数即可，如果想要获取更多的参数，可在后面跟一个`HttpServletRequest`对象。 ```java @Open("goods.add") @RequestMapping("/goods/add") public Object addGoods(GoodsParam param, HttpServletRequest request) { System.out.println(request.getParameter("method")); return param; } ``` ## 接口命名 接口命名没有做强制要求，但我们还是推荐按照下面的方式进行命名： 接口名的命名规则为：`服务模块.业务模块.功能模块.行为`，如： - mini.user.userinfo.get 小程序服务.用户模块.用户信息.获取 - member.register.total.get 会员服务.注册模块.注册总数.获取 如果觉得命名规则有点长可以精简为：`服务模块.功能模块.行为`，如`member.usercount.get`，前提是确保前缀要有所区分，不和其它服务冲突。 ## 测试接口 - 在sop-test工程下新建一个测试用例，`StoryDemoTest`，继承TestBase ```java public class StoryDemoTest extends TestBase { String url = "http://localhost:8081"; String appId = "2019032617262200001"; // 私钥 String privateKey = "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";
