+# swagger-api
 
+## Quick Start
 
+
 
+在项目中引入openapiv2
 
+
 
+```go
 
+import	"github.com/go-kratos/swagger-api/openapiv2"
 
+
 
+h := openapiv2.NewHandler()
 
+//将/q/路由放在最前匹配
 
+httpSrv.HandlePrefix("/q/", h)
 
+```
 
+
 
+支持generator进行自定义配置
 
+```go
 
+h := openapiv2.NewHandler(openapiv2.WithGeneratorOptions(generator.UseJSONNamesForFields(true), generator.EnumsAsInts(true)))
 
+```
 
+更多配置参见 https://github.com/go-kratos/grpc-gateway/blob/master/protoc-gen-openapiv2/generator/option.go
 
+
 
+
 
+启动应用后,在浏览器中输入 [http://\<ip>:\<port>/q/services](http://ip:port/q/services)，在顶栏右侧选框选取希望查看的服务名，即可浏览接口文档。
 
+![select service](/img/swagger.png)
 
+
 
+## FAQ
 
+#### 1. 如果启动时顶栏选框未显示可选的服务名，或访问/q/services出现报错，`failed to decompress enc: bad gzipped descriptor: EOF`的报错说明部分依赖的proto文件生成的路径不对导致的，
 
+比如:
 
+- api/basedata/tag/v1/tag.proto
 
+- api/basedata/article/v1/article.proto
 
+
 
+当 **api/basedata/article/v1/article.proto** import "api/basedata/tag/v1/tag.proto"时 ，生成的依赖为api/basedata/tag/v1/tag.proto 
+但是 tag.proto 生成的tag.pb.go文件中source是tag.proto（漏掉了api/basedata/tag/v1/）导致了依赖未找到
 
+
 
+此时需要生成tag.pb.go时kratos proto client api/basedata/tag/v1/tag.proto 补全proto的路径，这样生成的tag.pb.go文件中source就是正确的(api/basedata/tag/v1/tag.proto)
 
+
 
+#### 2. 给swagger api添加说明、examples
 
+请参考[a_bit_of_everything](https://github.com/grpc-ecosystem/grpc-gateway/blob/master/examples/internal/proto/examplepb/a_bit_of_everything.proto)，同时注意需要将[annotations.proto](https://github.com/go-kratos/kratos/blob/main/third_party/protoc-gen-openapiv2/options/annotations.proto)和[openapiv2.proto](https://github.com/go-kratos/kratos/blob/main/third_party/protoc-gen-openapiv2/options/openapiv2.proto)这两个proto文件复制到third_party/protoc-gen-openapiv2/options目录下
