+# bilibili-webapp
+
+微信小程序接口，使用protobuf生成的
+
+生成工具是[protoc-gen-go_api](https://github.com/dev-openapi/protoc-gen-go_api)
+
+
+## 如何使用
+
+在自己的项目中添加此包 github.com/dev-openapi/bilibili-webapp
+
+初始化包 `biliOauthService := biliwebapp.NewOauthService()`
+
+然后根据自己的需要，用`biliOauthService`去调用想用的接口
+
+## 如何添加新接口
+
+首先要安装protoc,protoc-gen-go和protoc-gen-go_api。前面两个如何安装，请参考网上教程搜索
+
+```shell
+go install github.com/dev-openapi/protoc-gen-go_api@latest
+```
+
+下载[protocol](https://github.com/dev-openapi/protocol)仓库
+
+下载本项目，与protocol是同一级目录
+
+然后根据文档在protocol项目中写好proto文件，再执行make bilibili-webapp会自动生成到本项目目录，最后提交两个项目即可
