name: "\U0001F4A1 Feature Request"
about: For ideas or feature requests, start a new discussion.
title: "[Feature]"
labels: feature
assignees: ''
---
Please see the FAQ in our main README.md before submitting your issue.
<!--
In order to accurately distinguish that the needs put forward by users are the needs of most users and reasonable needs, solicit community opinions through the process, and the features adopted by the community will be realized as new functions.
In order to make the proposal process as simple as possible, the process includes three stages: feature request - > proposal - > pull-request, where feature, proposal is issue and pull-request is the specific function implementation.
### Feature-request
In order to help the community correctly understand the requirements of the feature, the feature request issue needs to describe the functional requirements and relevant references or documents in detail. And the feature request issue can contain the basic description of the function, which can be used as a reference for the function implementation in the proposal.
### Proposal
Proposal contains the basic implementation methods of functions, such as interface definition, general usage of functions, etc.
### Pull-request
After the function is realized, a merge request will be initiated to associate the proposal issue with the function issue. After the merger is completed, all questions will be closed and the process will end.
### Decision process
When more than five maintainer members agree to implement the feature, a proposal issue will be created for detailed design. The status of the proposal is divided into: under discussion, finalized and abandoned. After reaching the final status, start specific implementation (PR can also be implemented synchronously during the discussion)
### Final decision maker mechanism
If the maintainer team members have major differences on a requirement, the final decision is made by @Terry Mao.
-->
### What problem is the feature used to solve?
<!--
example:
We hope to add event interface to Kratos framework to access middleware such as Kafka and rabbitmq
-->
### Requirements description of the feature
<!--
example:
The event interface should be added to Kratos. The interface should contain subscribers and publishers, and the message body should contain key value head
-->
### References
<!--
example:
- [nats](http://xxxxx)
- [kafka](http://xxxxx)
- [rabbitmq](http://xxxxx)

### Proposal description
<!--
example:
Add event interface for accessing message oriented middleware
-->
### Implementation mode
<!--
```go
example:
type Message interface {
Key() string
Value() []byte
Header() map[string]string
Ack() error
Nack() error
}
type Handler func(context.Context, Message) error
type Event interface {
Send(ctx context.Context, key string, value []byte]) error
Receive(ctx context.Context, handler Handler) error
Close() error
}
````
-->
### Usage demonstration
<!--
example:
```go
msg := kafka.NewMessage("kratos", []byte("hello world"), map[string]string{
"user": "kratos",
"phone": "123456",
})
err := sender.Send(context.Background(), msg)
```

# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
iammao@vip.qq.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage],
version 2.0, available at
https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
Community Impact Guidelines were inspired by [Mozilla's code of conduct
enforcement ladder](https://github.com/mozilla/diversity).

The kratos community wants to be helped by a wide range of developers, so you'd like to take a few minutes to read this guide before you mention the problem or pull request.
## Reporting Bug or Fixing Bugs
We use GitHub issues to manage issues. If you want to submit , first make sure you've searched for existing issues, pull requests and read our [FAQ](https://go-kratos.dev/docs/intro/faq).
When submitting a bug report, use the issue template we provide to clearly describe the problems encountered and how to reproduce, and if convenient it is best to provide a minimal reproduce repository.
## Adding new features
In order to accurately distinguish whether the needs put forward by users are the needs or reasonable needs of most users, solicit opinions from the community through the proposal process, and the proposals adopted by the community will be realized as new feature.
In order to make the proposal process as simple as possible, the process includes three stages: proposal, feature and PR, in which proposal, feature is issue and PR is the specific function implementation.
In order to facilitate the community to correctly understand the requirements of the proposal, the proposal issue needs to describe the functional requirements and relevant references or literature in detail.
When most community users agree with this proposal, they will create a feature issue associated with the proposal issue.
The feature issue needs to describe the implementation method and function demonstration in detail as a reference for the final function implementation.
After the function is implemented, a merge request will be initiated to associate the proposal issue and feature issue.
After the merge is completed, Close all issues.
## How to submit code
If you've never submitted code on GitHub, follow these steps:
- First, please fork items to your GitHub account
- Then create a new feature branch based on the main branch and name it features such as feature-log
- Write code
- Submit code to the far end branch
- Submit a PR request in github
- Wait for review and merge to the main branch
**Note That when you submit a PR request, you first ensure that the code uses the correct coding specifications and that there are complete test cases, and that the information in the submission of the PR is best associated with the relevant issue to ease the workload of the auditor.**
## Conventional Commits

## About Kratos
## Features
> The name is inspired by the Greek-mythology-based game "God of War". It tells the adventures of Kratos becoming a god of war from a mortal and launching a god-killing slaughter. * HTTP Blademaster:核心基于[gin](https://github.com/gin-gonic/gin)进行模块化设计,简单易用、核心足够轻量;
* GRPC Warden:基于官方gRPC开发,集成[discovery](https://github.com/bilibili/discovery)服务发现,并融合P2C负载均衡;
Kratos is a microservice-oriented governance framework implemented by golang, which offers convenient capabilities to help you quickly build a bulletproof application from scratch, such as: * Cache:优雅的接口化设计,非常方便的缓存序列化,推荐结合代理模式[overlord](https://github.com/bilibili/overlord);
* Database:集成MySQL/HBase/TiDB,添加熔断保护和统计支持,可快速发现数据层压力;
- The [communication protocol](https://go-kratos.dev/en/docs/component/api) is based on the HTTP/gRPC through the definition of Protobuf. * Config:方便易用的[paladin sdk](https://go-kratos.github.io/kratos/#/config),可配合远程配置中心,实现配置版本管理和更新;
- Abstract [transport](https://go-kratos.dev/en/docs/component/transport/overview) layer support: [HTTP](https://go-kratos.dev/en/docs/component/transport/http) / [gRPC](https://go-kratos.dev/en/docs/component/transport/grpc). * Log:类似[zap](https://github.com/uber-go/zap)的field实现高性能日志库,并结合log-agent实现远程日志管理;
- Powerful [middleware](https://go-kratos.dev/en/docs/component/middleware/overview) design, support: [Tracing (OpenTelemetry)](https://go-kratos.dev/en/docs/component/middleware/tracing), [Metrics (Prometheus is default)](https://go-kratos.dev/en/docs/component/middleware/metrics), [Recovery](https://go-kratos.dev/en/docs/component/middleware/recovery) and more. * Trace:基于opentracing,集成了全链路trace支持(gRPC/HTTP/MySQL/Redis/Memcached);
- [Registry](https://go-kratos.dev/en/docs/component/registry) interface able to be connected with various other centralized registries through plug-ins. * Kratos Tool:工具链,可快速生成标准项目,或者通过Protobuf生成代码,非常便捷使用gRPC、HTTP、swagger文档;
- The [standard log interfaces](https://go-kratos.dev/en/docs/component/log) ease the integration of the third-party log libs with logs collected through the *Fluentd*.
- Automatically support the selection of the content [encoding](https://go-kratos.dev/en/docs/component/encoding) with Accept and Content-Type. ## Quick start
- Multiple data sources are supported for [configurations](https://go-kratos.dev/en/docs/component/config) and dynamic configurations (use atomic operations).
- In the protocol of HTTP/gRPC, use the uniform [metadata](https://go-kratos.dev/en/docs/component/metadata) transfer method. ### Requirments
- You can define [errors](https://go-kratos.dev/en/docs/component/errors/) in protos and generate enums with protoc-gen-go.
- You can define [verification rules](https://go-kratos.dev/en/docs/component/middleware/validate) in Protobuf supported by the HTTP/gRPC service. Go version>=1.13
- [Swagger API](https://go-kratos.dev/en/docs/guide/openapi) is generated Automatically and embed Swagger UI endpoint can be started by adding [Swagger plugin](https://github.com/go-kratos/swagger-api).
### Installation
Kratos is accessible, powerful, and provides tools required for large, robust applications.
## Learning Kratos
Kratos has the most extensive and thorough [documentation](https://go-kratos.dev/en/docs/getting-started/start) and [example](https://github.com/go-kratos/examples) library of all modern web application frameworks, making it a breeze to get started with the framework.
We also provide a [modern template](https://github.com/go-kratos/kratos-layout). This template should help reduce the work required to setup up modern projects.
### Goals
Kratos boosts your productivity. With the integration of excellent resources and further support, programmers can get rid of most issues might encounter in the field of distributed systems and software engineering such that they are allowed to focus on the release of businesses only. Additionally, for each programmer, Kratos is also an ideal one learning warehouse for many aspects of microservices to enrich their experiences and skills.
### Principles
* **Simple**: Appropriate design with plain and easy code.
* **General**: Cover the various utilities for business development.
* **Highly efficient**: Speeding up the efficiency of businesses upgrading.
* **Stable**: The base libs validated in the production environment have the characteristics of high testability, high coverage as well as high security and reliability.
* **Robust**: Eliminating misusing through high quality of the base libs.
* **High-performance**: Optimal performance excluding the optimization of hacking in case of *unsafe*. 
* **Expandability**: Properly designed interfaces where you can expand utilities such as base libs to meet your further requirements.
* **Fault-tolerance**: Designed against failure, enhance the understanding and exercising of SRE within Kratos to achieve more robustness.
* **Toolchain**: Includes an extensive toolchain, such as the code generation of cache, the lint tool, and so forth.
## Getting Started
Create a kratos playground through [docker](https://www.docker.com/products/docker-desktop):
```shell
docker run -it --rm -p 8000:8000 --workdir /workspace golang
```
```shell
apt-get update && apt-get -y install protobuf-compiler
export GOPROXY=https://goproxy.io,direct
go install github.com/go-kratos/kratos/cmd/kratos/v2@latest && kratos upgrade
```
```shell ```shell
kratos new helloworld # Linux/macOS
cd helloworld/ && go mod tidy GO111MODULE=on && go get -u github.com/go-kratos/kratos/tool/kratos
kratos run
# Windows (Powershell)
go env -w GO111MODULE=on ; go get -u github.com/go-kratos/kratos/tool/kratos
# Windows (CMD)
go env -w GO111MODULE=on && go get -u github.com/go-kratos/kratos/tool/kratos
cd $GOPATH/src
kratos new kratos-demo
``` ```
Use a browser to open and visit: `http://localhost:8000/helloworld/kratos`, The kratos program is running!
If you need more, please visit the kratos [documentation](https://go-kratos.dev/en/docs/getting-started/start). 通过 `kratos new` 会快速生成基于kratos库的脚手架代码,如生成 [kratos-demo](https://github.com/bilibili/kratos-demo)
## Security Vulnerabilities ### Build & Run
If you discover a security vulnerability within Kratos, please send an e-mail to tonybase via go-kratos@googlegroups.com. All security vulnerabilities will be promptly addressed. ```shell
