Goproxy

A minimalist Go module proxy handler.

Goproxy has fully implemented the GOPROXY protocol. The goal of this project is to find the most dead simple way to provide a minimalist handler that can act as a full-featured Go module proxy for those who want to build their own proxies.

Features

• Extremely easy to use
  • Three structs: goproxy.Goproxy, goproxy.GoFetcher, and goproxy.DirCacher
  • Two interfaces: goproxy.Fetcher and goproxy.Cacher
• Built-in support for GOPROXY, GONOPROXY, GOSUMDB, GONOSUMDB, and GOPRIVATE
• Supports serving under other Go module proxies by setting GOPROXY
• Supports proxying checksum databases
• Supports Disable-Module-Fetch header

Installation

• To use this project programmatically, go get it:

go get github.com/goproxy/goproxy

• To use this project from the command line, download the pre-built binaries from here or build it from source:

go install github.com/goproxy/goproxy/cmd/goproxy@latest

• To use this project with Docker, pull the pre-built images from here:

docker pull ghcr.io/goproxy/goproxy

Quick Start

Write code

Create a file named goproxy.go:

package main

import (
	"net/http"

	"github.com/goproxy/goproxy"
)

func main() {
	http.ListenAndServe("localhost:8080", &goproxy.Goproxy{})
}

Then run it with a GOMODCACHE that differs from go env GOMODCACHE:

GOMODCACHE=/tmp/goproxy-gomodcache go run goproxy.go

Finally, set GOPROXY to try it out:

go env -w GOPROXY=http://localhost:8080,direct

For more details, refer to the documentation.

Run from command line

Refer to the Installation section to download or build the binary.

Then run it with a GOMODCACHE that differs from go env GOMODCACHE:

GOMODCACHE=/tmp/goproxy-gomodcache goproxy server --address localhost:8080

Finally, set GOPROXY to try it out:

go env -w GOPROXY=http://localhost:8080,direct

For more details, check its usage:

goproxy --help

Run with Docker

Refer to the Installation section to pull the image.

Then run it:

docker run -p 8080:8080 ghcr.io/goproxy/goproxy server --address :8080

Finally, set GOPROXY to try it out:

go env -w GOPROXY=http://localhost:8080,direct

For more details, check its usage:

docker run ghcr.io/goproxy/goproxy --help

Modify

此工程改造了原始goproxy，增加了通过文件上传依赖功能，为其添加了/* POST接口，可通过任意HTTP路径，采用POST方法上传依赖文件，具体代码位于goproxy.go文件中的serveSync方法之中，可查询此方法进行修改。

若需重新编译并制作镜像，可在有网环境下执行docker build -t goproxy:v0.16-upload .命令制作镜像，然后进行使用。

Usage

手动上传依赖

1. 有网构建工程，下载依赖

   在有网环境中，构建简单的 go module 项目，通过 import 导入所需依赖，然后通过 go mod tidy 下载依赖到本机的 go env GOMODCACHE 目录之下

2. 打包依赖

   通过以下代码打包依赖

   tar -zcf download.tar.gz -C $(go env OMODCACHE)/cache/download .

3. 拷贝依赖包到无网环境

4. 上传依赖包

   1. 通过界面上传

      访问 goproxy 程序的 / 路径，通过界面选择文件进行上传即可

   2. 通过 curl 上传

      示例代码如下

       filePath=/home/test/download.tar.gz # 设置要上传文件路径
       proxyServer=http://localhost:8080/ # 代理地址
       curl --request POST --url ${proxyServer} --header 'content-type: multipart/	form-data' -F "file=@${filePath};type=file -b --mime-type ${filePath}"
